Title: 2-position solenoid valve
Inventor: OOTOMO AKIHIRO
IPC: F16K31/06
Filed: 1989-02-10
Abstract: PURPOSE:To reduce the size and the weight of a valve, to eliminate a spacer, and to enable reliable execution of operation with high response by a method wherein the one of a core and a yoke is protruded from the end surface of the other, and the area of the end surface of the protruding one of the core and the yoke is reduced to a value lower than that of the end surface of the other. CONSTITUTION:Provided, under the non-energizing state of a solenoid coil 14, a gap between a core 12 and a plunger 16 is delta1 and a gap between a yoke 24 and the plunger 16 is delta2, a relation of delta1<delta2 is satisfied between the two gaps. Provided the area of the end surface, positioned facing the plunger 16, of the core 12 is S1 and the area of the end surface, positioned facing the plunger 16, of the yoke 24 is S2, a relation of S1/S2 is satisfied between the two areas. Since a 2-position solenoid valve 10 is formed in a manner described above, despite of the plunger 16 formed such that it is flat and has a low occupying volume and is reduced in size and weight, the plunger generates a high operation force higher than that of a cylindrical plunger and provides high response. Besides, the solenoid valve eliminates a spacer and enables reliable execution of a valve motion.

Title: Resistance ink for strain gage and strain gage
Inventor: MAEDA RYOICHI
IPC: G01B7/16
Filed: 1994-03-02
Abstract: PURPOSE:To improve a gage factor by a method wherein at least one out of graphite and a metal powder is diffused, as a main conductive material, to a thermosetting resin so as to form a resistance ink. CONSTITUTION:When graphite or a metal powder is used as a main conductive component, a gage factor is lowered when the mixture amount of the metal powder is too much, but a resistance becomes too high and unstable when the mixture amount is small. As a result, e.g. in the case of graphite and a pehnolic-resin binder, the content of graphite is set at 8 to 25vol.%. In addition, since the metal powder alone is stable and a high resistance is hard to obtain, graphite is mixed. In addition, when a thermoplastic resin is used as a binder, its hysteresis is large and it is unsuitable for a sensor. As a result, a thermosetting resin is used. An ink which is composed in this manner is printed on an insulation-treated phosphor bronze plate, it is heated and hardened, and a resistor is formed. Thereby, it is possible to obtain the printed resistor which is suitable for a strain gage.
