摘要:
A composite ceramic material which is available by sintering a mixed powder of a dielectric material and a magnetic material, and contains a third component serving to inhibit a chemical reaction between the dielectric material and the magnetic material during sintering of the mixed powder and reduce the sintering temperature, and particularly, an EMI filter, a composite LC pan and a composite LC chip part made from such a composite ceramic material. The starting end and the terminal end of the inductor are exposed on the both end faces of the bare chip, and signal electrodes are provided at these ends. Ends of the conductors for grounding are exposed on the other both ends of the bare chip, and grounding electrodes are provided at these ends. The conductors for inductor are spirally connected in succession in the thickness direction of the bare chip via throughholes provided in the sheets within the bare chip to form an inductor. The conductors for grounding are adjacent to, and spaced apart by a distance sufficient for insulation from the conductors for inductor in a plane within the bare chip and piled up alternately with the conductors for inductor to form capacitors each between a conductor for grounding and a conductor for the inductor.

A reservoir for holding fluid of a vehicle includes a tank and two brackets integrated with the tank to install the tank in the vehicle in an upper portion of the engine compartment. An attaching portion is arranged with each of the brackets to be fixed to the vehicle. A connecting portion is arranged with each of the brackets to connect the attaching portion to the tank. One of the connecting portions has a notch that is deformed or fractured so that the tank can be moved with respect to the vehicle to absorb an impact force that acts on the tank when the tank receives an impact force larger than a predetermined value. The attaching portion has a plurality of rib portions that is deformable or fracturable so that the tank can be moved with respect to the vehicle to absorb force that acts to the tank when the tank receives a force larger than a predetermined value.

In order to supply a heat exchanger of the passenger room heating system with sufficiently heated liquid coolant of the boiling liquid engine cooling system, the coolant inlet conduit of the heat exchanger is connected to a coolant jacket of the engine at a position close to highly heated portions of the engine (such as, the combustion chamber walls, exhaust port walls or the like defined in the cylinder head of the engine).

In order to quickly bring the temperature of both the engine and the engine lubricant up to desired operational temperatures and subsequently prevent overheating of the same, an oil cooler is integrated with an evaporative type engine cooling system in a manner that the temperature of the engine oil is controlled essentially in parallel with engine coolant. The engine load and/or engine speed are sampled and the cooling system operated in a manner to vary the boiling point of the coolant in accordance therewith.

A supercharged engine intercooler includes a coolant jacket in heat exchange with the hot compressed air from the supercharger. The coolant in the jacket is permitted to boil and the vapor condensed in a radiator. The rate of condensation during high engine load is maintained sufficiently high to induce sub-atmospheric pressures within the radiator and coolant jacket which lowers the boiling point of the coolant, while during low load operation the rate of condensation can be reduced to raise the pressure in the coolant jacket and thus the boiling point of the coolant to rise above 100.degree. C. Upon stoppage of the engine, the coolant jacket and radiator are completely filled with liquid coolant to prevent contaminating atmospheric air from leaking into the system.

A cylinder block comprises an upper section having a plurality of engine cylinder bores therein, the upper section having first and second oppositely disposed wall members, and a skirt section having a cavity defining a crankcase for an engine crankshaft, the skirt section having first and second oppositely disposed walls which are integral to and in straight alignment with the first and second wall members of the upper section, respectively, thereby effectively preventing noise radiation from the skirt section and improving the torsional and flexural rigidities of the cylinder block.
摘要:
In an engine system wherein the engine coolant is permitted to boil and the gaseous coolant used as a vehicle for removing heat from the engine, a heating jacket associated with the induction conduit of the engine is supplied with gaseous coolant via a control valve during cold engine starts and during modes of engine operation wherein it is advantageous from the view point of fuel economy to raise the temperature of the engine and/or the incoming fuel charge. The supply is terminated under other modes of operation to avoid heating the incoming charge and reducing charging efficiency.

An internal combustion engine comprises a cylinder block having a plurality of main bearing bulkheads, and a skirt section. Each bearing bulkhead is formed with through-holes each of which as an upper end opening to the skirt section and a lower end opening to the bottom surface of the bearing bulkhead. The bearing bulkhead is formed at its bottom surface with a depression. Each of a plurality of bearing caps is installed to the bearing bulkhead in a manner to fit in the bearing bulkhead depression. Additionally, bolts are disposed respectively in the bearing bulkhead through-holes, each bolt having an upper end section located on the skirt section and a lower end section located in the hole formed in the bearing cap, thereby eliminating the need for excess structure on the bearing cap to sharply reduce the weight of the bearing cap.

A cylinder block of an internal combustion engine, comprises a plurality of main bearing bulkheads, two oppositely disposed oil pan installation flange portions which are integral with the bearing bulkheads and made of a light alloy same as the bearing bulkheads, and a reinforcement member cast in and embedded throughout each oil pan installation flange portion and each main bearing bulkhead bottom section, the material of said reinforcement member being different from and high in mechanical strength than the light alloy, thereby greatly improving the rigidity of each bearing bulkhead bottom section to prevent each bearing bulkhead bottom section from vibrating.
摘要:
A sampling pulse generator circuit for a stereo demodulator circuit of a sample and hold system is disclosed. The pulse generator circuit uses pilot signals of an FM stereo broadcast as an input and produces output sampling pulses, which are phase-synchronized to the stereo subcarrier but have a 180.degree. phase difference to each other. The pulse generator circuit comprises a phase lock loop circuit having a multiple number of frequency dividers arranged in cascade. Selected outputs of these frequency dividers are logically summed to produce the output sampling pulses with a predetermined and stable pulse width.
