Title: Temperature controller for hot-air generator
Inventor: SUZUKI TOSHIAKI
IPC: F26B21/10
Filed: 1980-04-23
Abstract: PURPOSE: To maintain the temperature of the generated hot air at a given value in either case where a hot-air generator is changed over so as to generate a directly- heated air or an indirectly-heated air, by using a single temperature controller.  
     CONSTITUTION: The opening degree of a regulating damper 8 is regulated by means of a sensor which detects the temperature of a hot-air duct D. In the state where a directly-heated air is generated, the amount of the outside air, which is sucked from an intake 70 and sent into the hot-air duct D by means of a fan F in order to dilute the combustion gas, is regulated so that the temperature of the hot air formed from said combustion gas and the outside air is regulated. On the other hand, in the state where an indirectly-heated air is generated, the amount of the outside air taken into a heat exchanger E from the intake 70 is regulated so that said outside air becomes an indirectly-heated air through exchanging heat with the combustion gas in the duct of the heat exchanger E. Thereby, the temperature of the generated indirectly-heated air is regulated.

Title: Thyristor
Inventor: SHIMIZU YOSHITERU
IPC: H01L29/74
Filed: 1988-03-09
Abstract: PURPOSE:To improve a thyristor in a critical ON-current increase rate (di/dt) resistance and a switching power resistance by a method wherein an injection efficiency of the n emitter layer of a pilot thyristor region is made smaller than that of the n emitter layer of a main thyristor. CONSTITUTION:The impurity concentration of an n emitter layer 5 of a main thyristor is made higher than that of an n emitter layer 7 of a pilot thyristor, or the n emitter layer 5 of the primary thyristor is made thicker than the n emitter layer 7 of the pilot thyristor so as to make an injection efficiency of the n emitter layer 7 of the pilot thyristor region smaller than that of the n emitter layer 5 of the primary thyristor. In result, a current flows through the main thyristor more easily than the pilot thyristor, and when the pilot thyristor starts turning on, the current flows immediately to the primary thyristor. By these processes, the concentration of the current at the initial stage of turn-ON is prevented, so that a thyristor excellent in the di/dt resistance and switching power resistance can be obtained.

IPC: F16C27/00
Filed: 1980-04-25
Abstract: PURPOSE: To stabilize the damping characteristics of the bearing by a method wherein a communicating passage, opening one end thereof in an annular groove on a flat surface facing to a horizontal surface in a bearing box while opening the other end thereof at the lower part of an oil film chamber, is provided.  
     CONSTITUTION: The annular groove 11 is provided on a flat surface 10 and the communicating passage 12 opens one end thereof in the annular groove 11 and the other end thereof at the lower part of the oil film chamber 6 respectively. When a rotary shaft 2 is rotated, oil is bitten into a clearance 5 due to the function of screw grooves 3 and the pressure of the oil film chamber 6 becomes high. This pressure is propagated to a clearance 8 between the horizontal surface 9 and the flat surface 10 through the communicating passage 12 and the annular groove 11 and pushes up a floating board 7 to form an oil film. A vibration absorbing function is provided by utilizing the shear resisting force of this oil film section. The  pressure in the oil film chamber 6 is determined substantially by the thrust load of  the bearing 4, therefore, a force to push up the floating board 7 is constant substantially. Accordingly, the thickness of the oil film formed in the clearance 8 becomes  constant substantially thereby stabilizing the damping characteristics of the bearing.
