Title: Electric inertia control device for power transmission system tester
Inventor: ITO JIRO
IPC: G01M13/02
Filed: 1991-07-19
Abstract: PURPOSE:To compensate inertia over a wide range with high response by providing an electric inertia control means constituted so as to calculate inertia resistance corresponding torque according to a specific formula. CONSTITUTION:When input torque T1 is outputted by an output command device 108, an input motor 101 receiving adjusted voltage 104 outputs the same torque as the input toreque T1 to rotate an input shaft 1a by N1-times. An electric inertia control means calculates the torque T2 generated by rotating an output shaft 1b N2-times by multiplying the command value T1 by a rotation ratio i=N1/N2 by a multiplier 10 and further subtracts running resistance corresponding toreque TR set by a setting device 208 by a subtractor 11 to calculate difference DELTAT. The value obtained by multiplying the difference DELTAT by the output = object tested inertia Im/vehicle equivalent inertia quantity Ic of a divider 14 by a multiplier 12 is subtracted from the difference DELTAT by a subtractor 13. That is, an operation formula TA=T (1-Im/Ic) is operated to calculated the inertia resistance corresponding toreque TA of the output shaft 1b and an output motor 201 is controlled on the basis of the torque TA and the angular velocity of rotation coinciding with the inertia quantity Ic can be calculated and a differentiator becomes unnecessary and response can be improved. Since the operation of the torque TA is performed outside torque control systems on input and output sides, the limit of an inertia compensation range is eliminated.

Title: Forming method of insulating thin film
Inventor: TSUNEKAWA SUKEYOSHI
IPC: H01L21/31
Filed: 1980-12-22
Abstract: PURPOSE:To reduce damage affected on a semiconductor element even if a negative voltage is induced in a substrate during thin film formation by a method wherein in the formation of an insulating thin film by a high frequency sputtering method, a temperature of a substrate is maintained at a specific value. CONSTITUTION:According to the experimental result on the effect of a substrate temperature on a high frequency sputtering method, when the substrate temperature is maintained to be 200 deg.C or below, a variation in a flat band voltage after formation of an SiO2 film is high, but because of restoration of the flat band voltage to an initial value through heat-treatment, a substrate temperature should be maintained at or below approximately 250 deg.C to minimize an effect on a characteristics of an element. On the other hand, because an etching speed is heightened and the film is degraded when the substrate temperature is lowered, a lowest limit of the substrate temperature should be set at or above 150 deg.C that is within a range in whcih an effect on a substrate bias by a fine configuration of an SiO2 film is not canceled.
