A surface-treated metal according to an exemplary embodiment of the present invention can include a metal base material, and an inorganic-organic composite film formed on at least a portion of a surface of the metal base material. The inorganic-organic composite film may have a siloxane bond as a main bond in a main skeleton. The film may further have, in bonds of either or both of the main skeleton and/or a side chain, either or both of an ether bond and/or an amino bond. The film may also include an alkyl group having 1 to 12 carbon atoms, an aryl group, a carboxyl group, an amino group, and/or a hydroxyl group.

An inkjet printer capable of printing pictorial diagrams and characters clearly without smearing using a solvent ink. A preheater for preliminarily heating the medium forwardly carried toward below the traveling path of the printing head on a rear part of the platen and a print heater for heating the medium that has been carried onto the platen, on which the inkjet droplets ejected from the nozzles of the printing head are landed, are provided. Further, the ink droplets ejected from the nozzles of the printing head and landed on the surface of the medium are prevented from permeating the medium in the surrounding parts of landed points by heating and drying the ink droplets early on the surface part of the medium.

A swash plate compressor includes a cylinder block, a shaft rotatably supported in a central portion of the cylinder block a swash plate which rotates along with rotation of the shaft a crankcase for retaining the swash plate, and pistons each connected to the swash plate and sliding in a corresponding one of the cylinder bores as the swash plate rotates. Each of the pistons includes a hollow cylindrical portion for sliding within the cylinder bore and a bridge for rollably supporting the pair of shoes. The bridge projects radially outward with respect to the hollow cylindrical portion. The cylinder block is formed with a projecting portion projecting from a central portion of a front end face thereof toward the crankcase, within a range limited such that the projecting portion does not interfere with the connecting portion.

The present invention provides an evaporated fuel system diagnostic apparatus. The evaporated fuel system diagnostic apparatus includes a malfunction determination unit which determines whether a malfunction occurs in an evaporated fuel system, by introducing a negative pressure of an intake passage into a fuel tank. An operating condition setting unit sets, when the malfunction determination unit has started the introduction of the negative pressure of the intake passage into the fuel tank, an operating condition of an internal combustion engine in a predetermined condition that causes the negative pressure of the intake passage to be within a predetermined pressure range. Further, the present invention provides a vehicle control apparatus for an automotive vehicle equipped with the evaporated fuel system diagnostic apparatus.

摘要:
A test system for testing the quality of electric appliances includes a test line having an endless conveyer which is provided with a multiplicity of carts, a reception terminal for receiving electric appliances from a first assembly line on which the electric appliances were assembled, and an exit terminal for releasing the appliances to a second assembly line after they are tested. The reception and the exit terminals are connected with the assembly lines in response to a run signal instructing the operation of the test line. When the electric appliances are received at the reception terminal, they are each mounted on one of the carts for circulation in intermittent movement in response to the run signal. Located along the endless conveyor are a multiplicity of test stations, which are adapted to carry out required tests when the appliances are transported to the stations. Once a test is done on an electric appliance, the same test will not be repeated on the same electric appliance. The endless conveyor is disconnected from the assembly lines in response to a stop signal instructing the stopping of the test line, so that the conveyor becomes independent of the assembly lines and circulates the electric appliances in the test line. When the test line receives the stop signal, each of the electric appliances are allowed to make a complete circulation through the test line, starting from the position located at the time of reception of the stop signal, to complete pending tests, and then the test line is stopped. The test line may be incorporated in an assembly line, thereby improving the production efficiency of the lines.
摘要:
The present invention prevents a decrease in efficiency due to energy circulation in a power transmission path in a power output apparatus having an engine and a motor as power source. In the power output apparatus, a planetary gear 120 has a sun gear shaft linked with a generator MG1, a ring gear shaft linked with a motor MG2, and a planetary carrier linked with an output shaft of an engine 150. The power output apparatus carries out a control procedure to avoid energy circulation, which goes through the planetary gear 120, the motor MG2, and generator MG1, and the planetary gear 120, and thereby prevent a decrease in efficiency. The energy circulation occurs when the motor MG2 converts the power output from the engine 150 to electric power and the generator MG1 carries out power operation with the regenerated electric power. The control procedure monitors a torque command value of the motor MG2 and shifts a driving point of the engine 150 to another driving point of higher revolving speed when the torque command value is not greater than a threshold value Tref.
