Title: Seal device for use in press assembly
Inventor: POORU EMU KADEISU
IPC: B30B15/16
Filed: 1991-05-09
Abstract: PURPOSE: To provide an improved seal device used for the cushion assembly of the press device. CONSTITUTION: The cushion device consists of a piston 44 vertically movably fitted into a cylinder 42. The piston segments upper and lower variable volume chambers 46 and 48. The upper variable volume chamber houses liquid pressure fluid and is communicated with an accumulator 52 through an orifice 56. The lower variable volume chamber is particularly filled by nitrogen and is coupled to the accumulator through a conduit and is so pressurized as to maintain the pressure in the lower variable volume chamber. The seal device 100 used for the cushion device has a high-pressure piston seal 102, a high-pressure cylinder seal 104 and low-pressure outer seal 106 so as to shut off the flow of the respective fluids according to the vertical movements of the piston.  The high- pressure piston seal shuts off the flow of the fluids between the upper and lower variable volume chambers and the high-pressure cylinder seal shuts off the flow of the fluid from the upper variable volume chamber along the piston rod 68. The external pressure seal prevents the contamination from outside.

Title: Torque sensor
Inventor: SAITO NAOKI
IPC: G01L3/10
Filed: 1990-08-31
Abstract: PURPOSE:To prevent the fluctuation of the measured results by providing variable inductance means for changing the inductances of coils in response to the relative rotations between the movable members. CONSTITUTION:When AC is supplied from an oscillation circuit 31 into an exciting coil 22, the magnetic flux corresponding to the current is generated. Electromotive forces are generated across both ends of detecting coils 20 and 21. Therefore, when the number of the turns of the detecting coils 20 and 21 and the like are suitably selected, the overlapping degrees of through holes 23 and 24 and a through hole 25 are changed in response to steering torque as described above. Therefore, mutual inductances M1 and M2 are changed with the direction and the magnitude of the steering torque. The exact reverse characteristics with respect to the time when the torque crosses at a zero time point are obtained. The electromotive forces generated across both ends of the detecting coils 20 and 21 are determined by the mutual inductances M1 and M2. When the electromotive forces of the detecting coils 20 and 21 are measured in the circuit shown in the figure 5, the steering torque generated in the steering system can be detected.

Title: Circuit breaker
Inventor: TAKAHASHI SUSUMU
IPC: H01H73/18
Filed: 1995-09-07
Abstract: PROBLEM TO BE SOLVED: To miniaturize an arc-extinguishing device, by making it possible to reduce a groove width of a U-shaped groove by employing a heat resistant magnetic arc- suppressing plate which allows a composite plating layer to be easily formed on an inner surface of the U-shaped groove. SOLUTION: A composite plating layer 7, is made in such a manner that ceramic particles of silicon carbide or boron nitride or the like are dispersed in a non- electrolytic nickel plating liquid and separated out, in a eutectoid manner, on a surface of an acid metal plate 71 . The silicon carbide has a subliming temperature of, for example, 2200 deg.C and a melting point higher than 2700 deg.C, while a subliming point at a normal temperature and a melting point at a higher pressure of the boron nitride are both 3000 deg.C, and therefore the composite plating layer 72 endures a high temperature generated by an arc.  This layer 72 only needs a thickness on the order of 10μm to produce a sufficient effect and a heat resistant magnetic arc-suppressing plate 7 can do substantially without a thickness beyond that of the magnetic metal plate 71 , and therefore disposition of a plurality of plates becomes possible and an arc- extinguishing device can be miniaturized. The composite plating layer 72 is not limited to the said composition, but any combination will do so long as it is of a metal, which is excellent in heat resistance without damaging arc-extinguishing property, and a ceramic.
