Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for increasing the wall thickness of a work boss part in which the boss part can be formed by increasing a circumferential wall of a vertical cylindrical part of the work and the manufacturing cost can be reduced by one swaging operation without any more swaging operations.
SOLUTION: A plate part 10 of the work 1 is held by a work placement face 32 of a work supporting part 3 and a die 5 by performing one swaging operation to press the vertical cylindrical part 12 by a punch 6 in the swaging direction where L is the buckling preventive distance of preventing any buckling phenomenon of the vertical cylindrical part 12 of the work 1. In a state in which a wall thickness increasing space 65 is formed between a mandrel 4 and the vertical cylindrical part 12, the mandrel 4 is retracted in the swaging direction of a punch 6 while the material of the vertical cylindrical part 12 is allowed to flow into the space 65. The boss part is formed by increasing the thickness of the vertical cylindrical part 12 while maintaining the length of a swageable part of the vertical cylindrical part 12 to be within L, and the vertical cylindrical part 12 is swaged to shorten the length in the axial direction of the vertical cylindrical part 12.

Abstract: PROBLEM TO BE SOLVED: To suppress a structure defect by providing an aluminum oxide layer between a substrate and a piezoelectric body film. SOLUTION: A silicon substrate 2 whose surface is washed is installed in a vacuum tank for sputtering, and an Al target is used for forming an aluminum oxide thin film 4 by reactive sputtering. For an excitation gas, the ratio of oxygen to argon is set to 1 to 1. The sputtering is made by a DC power of 200 W for 30 minutes for obtaining the amorphous aluminum oxide thin film 4 with a thickness of approximately 100 nm. Then, the silicon substrate 2 is moved onto a PZT target, the excitation gas is set to pure argon, and the sputtering is made by an RF power 100 W for 90 minutes for forming an amorphous thin film. The silicon substrate 2 is taken out of a sputtering device and is subjected to annealing at 700 deg.C for two hours in oxygen atmosphere, the PZT is crystallized, a piezoelectric body film 6 is formed, and a lamination structure body 8 is obtained.

Abstract: PROBLEM TO BE SOLVED: To obtain a piezoelectric film in which temperature dependence of the characteristic values or the characteristics can be controlled while suppressing occurrence of defect by laminating piezoelectric layers of different composition or composition ratio through interfaces thereby forming a piezoelectric film. SOLUTION: A thin PLZT film (y=0.5) 8 of about 0.5 μm thick is formed on a thin platinum film 6 of about 10 nm thick formed on a silicon substrate 4, for example, and a thin PLZT film (y=0.65) 10 of about 0.5 μm thick is formed thereon. After repeating the film deposition process, a thin platinum film 12 of about 10 nm thick is formed on the thin PLZT film 10. It is then taken out from a sputtering system and thermally annealed in oxygen atmosphere to form a piezoelectric film 14 and a piezoelectric element. In such a piezoelectric film 14, even if a defect is present in one piezoelectric layer (any one of thin films 8, 10), it is confined within the film thickness and can be prevented easily from penetrating the entire piezoelectric film 14. Furthermore, a preferable dielectric constant can be obtained along with preferable temperature characteristics for resonance frequency.

Abstract: PROBLEM TO BE SOLVED: To execute sub-injection when temperature inside cylinders reach a target value. SOLUTION: Main injection of fuel is carried out from fuel injection valves 31 to 34 into cylinders 11 to 14 near a top dead center of compression. Post injection of the fuel is carried out from the fuel injection valves 31 to 34 into the cylinders 11 to 14 in an expansion process. In a fuel injection control device of such a diesel engine 1, the post injection timing is set at the time where the temperature inside the cylinders 11 to 14 are equalized to the target values. An ECU 100 obtains the post injection timing with reference to the compression dop dead center according to operation conditions of the diesel engine 1. The ECU 100 executes the post injection at this post injection timing.

Abstract: PROBLEM TO BE SOLVED: To provide a temperature estimation device for a vehicular frictional engaging device, capable of enhancing the estimating accuracy for temperature. SOLUTION: Temperature Tempc of an electromagnetic clutch 30 is estimated by a temperature estimating means 210 on the basis of each heating state of a bearing (input side) being situated in a peripheral part of this clutch 30 and rotatably supporting an input shaft and another bearing (output side) rotatably supporting an output shaft, from which this clutch is rotated as receiving load in the axial direction or a direction orthogonal with the shaft whereby each heating state of bearings generating relatively much heat is taken into account, and thus the temperature Tempc of the electromagnetic clutch 30 is more accurately estimated.

Abstract: PROBLEM TO BE SOLVED: To recover pressure rapidly by suppressing a fuel pressure from lowering immediately after the start of injection. SOLUTION: A pressure regulating passage 28 to connect a first fuel feed hole 27 to back pressure chamber 45 is provided, and a regulating valve 30 and a spring 31 are stored in a valve storing hole 29 installed half way in the pressure regulating passage 28. At the beginning of the opening of a control valve 10, fuel is delivered from the first fuel feed hole 27 to a fuel delivery passage 41 through a second fuel feed hole 40 and a back pressure passage 39, and fed from the first fuel feed hole 27 to the back pressure chamber 45 through the pressure regulating passage 28, a communicating hole 34 in the regulating valve, and the valve storing hole 29. Therefore a pressure drop inside the back pressure chamber 45 becomes slower, and an injection rage becomes lower. At the latter part of the injection, because the regulating valve 30 is brought in contact with the downstream end of the valve storing hole 29 so as to close the pressure regulating passage 28, fuel supply to the back pressure chamber 45 through the pressure regulating passage 28 is eliminated. Thus a pressure drop inside the back pressure chamber 45 becomes faster, and the injection rate becomes higher.

Abstract: PURPOSE: To shorten the operation time by obtaining the fuel injection timing to the top dead center according to the amount of time from the generation of a reference position signal of a crankshaft in the set time before fuel injection is started to the generation of an injection signal and the amount of time from the generation of a reference position signal to the top dead center. CONSTITUTION: A fuel injection timing measuring device comprises a lift sensor 1 for detecting the lift amount of a needle valve for adjusting the fuel oil consumption, a reference position sensor 2 and a crank angle sensor 3, wherein output signals of the sensors are taken in an injection timing monitor 100. In an operating part 120, before fuel injection from a fuel injection valve is started, a reference position signal for a crankshaft is generated in a preset time in the region of 30 to 90 deg. CCA. Subsequently, the amount of time from the generation of the reference position signal to the time when the lift sensor 1 generates an injection signal and the amount of time from the generation of a reference position signal to the top dead center are measured by using a crank angle signal generated by the crank angle sensor 3 to measure the fuel injection timing.

Abstract: PURPOSE:To prevent both a connecting pipe and a joint member from being excessively stressed when the connecting pipe is connected to a main pipe with the joint member. CONSTITUTION:A connecting pipe 3 is connected to a high pressure fluid flowing main pipe 1 with a joint 4. The joint 4 is furnished with a joint member 9 and with a fastening nut 10 which is threadedly fitted in the joint member 9. A projected rib 12 in a circular arc shape in cross section extended in the circumferential direction is formed over the circumferential surface of the main pipe 1. The hole 13 of the joint member 9 is coupled on the projected rib 12. The tip end surface 17 of the connecting pipe 3 is formed into a spherical one, so that the tip end spherical surface 17 is seated in a conical recessed groove 15 which is formed on the outer circumferential surface of the main pipe 1. When the fastening nut 10 is rotated to the fastening direction, fastening force is transmitted to the tip end section of the connecting pipe 3 via a spacer 20, so that the tip end spherical surface 17 of the connecting pipe 3 is brought into contact with the conical recessed groove 15 with pressure.
