IPC: H02H3/24
Filed: 1989-05-10
Abstract: PURPOSE:To prevent a power semiconductor device from being damaged by dividing a constant current driving signal and by stopping the operation of the power semiconductor device which the virtual junction temperature of the power semiconductor device is reduced to the maximum operation ambient temperature in abnormal heat emission based on the output signal of a comparator. CONSTITUTION:In case abnormal heat emission is caused to a power semiconductor device 1 when its virtual junction temperature is raised over the maximum virtual junction temperature, the voltage detected in a temperature detection section 31 and the threshold voltage of a comparator 6 as compared with the former will be the 1st threshold voltage corresponding to the maximum virtual junction temperature. Since the voltage detected in the temperature detection section 31 is less than the 1st threshold voltage, the output of the comparator 6 varies from a low level to a high level. During the period that the virtual junction temperature of the power semiconductor device 1 is reduced to its maximum operation ambient temperature, a constant current driving signal is divided into an output adjustment means 33 and the operation of the power semiconductor device 1 is stopped.

Filed: 1983-06-30
Abstract: PURPOSE:An aqueous synthetic resin dispersion excellent in adhesiveness, obtained by polymerizing a monomer mixture comprising vinyl chloride, vinyl acetate, and a specified compound in an aqueous medium in the presence of a vinyl chloride-soluble urethane polymer. CONSTITUTION:100pts.wt. monomer mixture comprising vinyl chloride, vinyl acetate, and an alkali metal or ammonium salt of allylsulfonic acid or methallylsulfonic acid and, optionally, other compolymerizable monomers is polymerized in an aqueous medium in the presence of 2-50pts.wt. vinyl chloride- soluble urethane polymer. When the amount of the urethane polymer is below 2pts.wt., the adhesive strength of the dispersion is low in bonding carried out at a temperature <=80 deg.C, and the tear strength of a film is low when used as a semi-adhesive coating, which is undesirable. On the contrary, when the amount of the urethane polymer exceeds 50pts.wt., the water and oil resistances are poor.

Title: Torque detecting device for rotary shaft
Inventor: GOTO YOSHIYUKI
IPC: G01L3/10
Filed: 1988-05-13
Abstract: PURPOSE:To obtain the high-accuracy device which has no temperature dependency by forming an oscillation circuit which oscillates at the resonance frequency of a resonance circuit by using the resonance circuit and a detection part and detecting a difference in rotation angle corresponding to torque as variation in oscillation frequency. CONSTITUTION:When a driven shaft 2 is rotated by a driving shaft 1, an elastic body 10 twists to generate the rotation angle difference on the rotary shaft. This angle difference allows the tip part of a metal core 32 to move in the cavity of a detection coil 31 in the entering or exiting direction and an eddy current generated at the core 32 varies to cause variation in the inductance of the coil 31. Consequently, the resonance frequency of the resonance circuit K coupled with a sensor part J varies and the oscillation frequency of a detection part provided outside the shaft varies. Then the quantity of the variation in the inductance of the coil 31 corresponds to the quantity of the torque, so the applied torque is detected from the quantity of variation in frequency. Consequently, the high-accuracy detecting device which has no temperature dependency is obtained.
