Title: Induction motor controller for vehicle
Inventor: YASUDA AKIO
IPC: H02K16/02
Filed: 1993-07-02
Abstract: PURPOSE:To provide an induction motor controller for coaxial double rotor type vehicle which allows excellent stabilized running even at the time of turning or running on a rough road. CONSTITUTION:The induction motor controller for coaxial double rotor type vehicle decides whether the ratio or the difference of slip between both squirrel- cage rotors deviates an allowable range (106), and sets a frequency value and a voltage value based on the lower slip when the allowable range is not deviated otherwise on the higher slip(108-116). Since the frequency and voltage values are controlled at all times based on the lower slip, the other slip does not enter into a substantial zero region even if it is not monitored constantly. Even when one wheel slips to decrease the slip of associated squirrel-cage rotor significantly, the frequency and voltage values are controlled based on the other sound wheel thus ensuring an optimal torque for the normal wheel.

IPC: H01L21/3065
Filed: 1987-06-30
Abstract: PURPOSE:To find out the end point of etching by detecting self-bias during gas etching with SF6. CONSTITUTION:In order to remove silicon contaminating substance deposited on the inner wall face of a reaction chamber 1, when a dummy substrate 2a of the same shape as a drumlike substrate 2 is mounted instead of the substrate 2, SF6 gas is introduced into the chamber, and a high frequency power is similarly applied between the substrate 2a and an electrode plate 3, a glow discharge is generated, etching cleaning is conducted upon decomposition of the gas. When the gas etching is executed, a potential difference is so generated, since the area of the electrode plate is larger than that of the peripheral face of the substrate, between both that the electrode plate becomes positive. When such a self-bias is detected by a recorder 5 during the continuation of the etching, its bias value is varied at its end point (b). Thus, a plasma spectrum producing window may not be attached to an etching chamber, there is no necessity of providing a spectroscope and a lock-in-up, and the end point can be simply and inexpensively located.
