Abstract: An electromagnetic valve for opening and closing a fluid flow passage by operating a plunger under a magnetic force of a solenoid. The valve comprises a valve head provided at one of opposite ends of the plunger, and a fixed valve seat including an orifice providing a fluid flow passage. The valve head is adapted to abut against the valve seat to close the orifice. A spring resiliently presses the valve head in a direction for abutment of the valve head against the valve seat to close the orifice. Either one of the valve head and the valve seat is formed from a metallic material and the other is formed from a non-metallic material having a greater hardness than the metallic material. It is preferred that the metallic material be a highly corrosion-resistant metal alloy containing Ni in a high amount ratio, and the non-metallic material be of a ceramic type.

Abstract: An actuator operated by a solenoid and a force amplifying means utilizing hydraulic pressure are used in combination with a diaphragm, to thereby provide a diaphragm valve made of Teflon™, and which is compact in size, has low power consumption, and which is capable of exerting a large force. The force amplifying means mainly comprises a cylinder including cylinder portions having different cross-sectional areas and oil filled in the cylinder. A force amplification ratio is equal to a ratio between the cross-sectional areas of the cylinder portions. A plunger which receives a biasing force of a spring is provided on an upper side of the force amplifying means. The plunger is operated by a solenoid, and a driving force of the plunger is amplified by the force amplifying means and transmitted to the diaphragm, thus adjusting a degree of valve opening.

Abstract: In the ink jet head unit of the present invention, an ink jet head for emitting ink in a formof droplets from nozzles formed in a nozzle face and a driving circuit for driving the ink jet head are mounted on the same surface side of the base board. A groove section is formed in the surface, extending from the nozzle face of the ink jet head to the driving circuit. In the ink jet head, a temperature measuring section is positioned in the groove section. Furthermore, there is provided a sealing member in the groove section, to prevent the flow of ink emitted from the nozzles, into the driving circuit. The sealing member is partly formed of an elastic body. Therefore, since the elastic body can restrain a change in the volume of the sealing member likely to be caused by a temperature change, it is possible to prevent the temperature change from impairing the ink jet head, consequently realizing ink projection stability.

Abstract: An object of the present invention is to provide a vehicle backward movement assisting apparatus during parking, in which a steering assisting guide display is performed so that a driver can easily comprehend a steering rate and time frame, a steering amount or a backward movement amount in parking a vehicle. When a vehicle starts a turn, a detecting means of a rotation speed difference between a right wheel and a left wheel detects a rotation speed difference between a right wheel and a left wheel. When the difference becomes the predetermined value or larger, it is recognized that the vehicle starts the turn. The angle speed, which is detected by a yaw rate sensor since the start of the turn, is added as a yaw angle. Then, the vehicle is stopped and a shift lever is operated so as to be set to a backward movement position, whereby the yaw angle at this time is detected as the turn angle since the time of starting the turn.

Abstract: A connector for a memory card 11 comprises the housing 12, the plate 14, the guide plate 16, the lock system 18, and the connector pin keeping part 20. Because the connector pin keeping part 20 is formed as horizontally bridged to a rear surface of the housing 12, and also the press-fitting part 40d of the connector pin 40 is press-fitted with a perpendicular state, the connector for a memory card 11 not only can be miniaturized but also can achieve a reduced thickness by restricting an amount protruding to a rear side within a small volume. Therefore, because a shape of the connector pin 40 is bent like a L-shape and the fixing hole 20a of the connector pin keeping part 20 is extended in an up-down direction and formed in the housing 12, it can promote the miniaturization and reduced thickness of the connector for a memory card 11. As a result, reducing a weight of the connector for a memory card 11 can also be attained.
