Patent JP-H01227320-A (JP)
Title: Thermostat
Inventor: SAKAMOTO TOSHIYUKI
IPC: H01H37/12
Filed: 1988-03-04
Abstract: PURPOSE:To facilitate assembly work and to simplify adjustment by twist- inserting a plate-shaped 1st stopper near the boundary between a close contact winding section and a pitch winding section of a tension spring and arranging such that the 1st stopper comes in contact with a 2nd stopper raised from a device frame just before a switch is turned on and that they part from each other just before the switch is turned off. CONSTITUTION:When a switch 40 is turned off, a cam 30 is turned to displace a cam arm 31 and to change the tension of a tension spring 32. The displacement, however, occurs only in a pitch winding section 36 and not in a close contact winding section 37. Still, the overall force of the tension spring 32 changes. As a result, turning off temperature changes. In the case of turning on, a 1st stopper 34 of the tension spring 32 comes in contact with a 2nd stopper 38 of a device frame 22 before the switch is turned on. After the contact, only the pitch winding section of the tension spring 32 displaces and impart bias force to a lever 25. Namely, the displacement of the pitch winding section 36 of the spring 32 becomes to have nothing to do with the turning on of the switch and the force for turning on, namely the temperature, becomes constant regardless of the position of a cam shaft 30.

Title: Protective device for electric rolling stock
Inventor: UJIIE AKIHIKO
IPC: B60L3/00
Filed: 1997-03-06
Abstract: PROBLEM TO BE SOLVED: To apply only gate-off for giving no circuit-breaker opening in detecting the temporary overcurrent of the secondary winding which is generated owing to normal disturbance. SOLUTION: This protective device for an electric rolling stock is formed so that the first overcurrent judgment means 9 may conduct its overcurrent judgment if the input current of a power converter becomes excessive, and according to this, the first signal output means 11 outputs a gate-off protective signal B to apply gage-off to a power semiconductor device. At the same time, the second overcurrent judgment means 10 conducts overcurrent judgment, a delay means 13 applies a constant delay to its output, and overcurrent discrimination output is applied to the second signal output means 12 if the input current of the power converter is not decreased so as to be lower than a reference value within the delay time, thus outputting a circuit-breaker open signal C.  It is thus possible to apply only gate-off for giving no unnecessary opening operation to a circuit breaker if the output current of the power converter becomes excessive due to normal disturbance.

Title: Solubilization of coal using olefin
Inventor: ARITA SEIJI
IPC: C10L9/02
Filed: 1978-04-28
Abstract: PURPOSE: To solubilize coal in a solvent, and manufacture a pollution-free, easy- handling, and easy-burning liquid fuel, by the heat treatment of coal dispersed in a heavy oil, under specific conditions in the presence of high pressure olefin, such as ethylene.  
     CONSTITUTION: Coal, esp. brown coal., is dispersed in a heavy oil, such as petroleum asphalt, etc., and heat treated under olefin pressure at 300W430°C for 30W150 min. with stirring. The presence of the olefin eliminates the necessity of catalysts, and gives higher solubilization rate under the milder conditions than the solubilization by hydrogen. Heavy oils derived from coal or petroleum can be used as the heavy oil, and the olefin may be a mixture of olefins. A fuel for a burner is produced by removing insoluble residue containing ash from the solubilized coal, and adding a proper amount of a viscosity controlling oil to the solubilized coal.
