Title: Inverter operation lead-in controller of motor
Inventor: MASUDA HIROYUKI
IPC: H02P23/07
Filed: 1984-04-27
Abstract: PURPOSE:To switch shocklessly a motor when switching to an inverter operation by a commercial power source by reducing an inverter frequency command by a level corresponding to the decrease in the rotating speed of the motor. CONSTITUTION:A multiplier 40 input a fvrequency correction signal DELTAVfm, and outputs a voltage signal V having a magnitude obtained by multiplying the value of the signal DELTAVfm by a constant. The signal V is added by an adder 42 through an analog switch 41 to the signal DELTAVfm, and the sum is supplied as an inverter frequency command to an oscillator 28. The switch 41 is closed by a lock detection signal of a lock detector 33. Thus, an inverter frequency command is corrected by the signal V siumultaneously upon reapplying of the voltage to decrease stepwisely. Accordingly, an increase in a slip until a torque is established is suppressed, and since the inverter output current is accordingly reduced, an overcurrent trip is prevented.

Abstract: PURPOSE:To reduce the manufacturing cost of contact type and complete contact type image sensors using a thin type, and to realize miniaturization by forming a capacitor having structure, in which an insulating film is held between a first thin-film electrode and a second thin-film electrode constituting a photoelectric transducer.

Filed: 1978-07-19
Abstract: PURPOSE: To improve reliability in a plastic seal type particularly by covering a device with a semiconductor surface and glass film and insulation film and setting the width of the glass film at a value less than 500μ.  
     CONSTITUTION: When a glass film is formed on an insulation film, if the width W of the glass film is too great, the film thickness is uneven and a pinhole is occurred in the thin portion, and this trend is intensified in the width over 500μ. In a SCR element, a SiO 2  film 8 is left on the end 6 and the upper face of a n-type and p-type guardring 4 and 5 in a n-type base, the other is covered with aglass 9. The glass film is divided and a guardring is arranged to restrict the width W less than 500μ. The width of the SiO 2  interleaved between the glass films is set at a value more than 40μ to prevent a compassing of the glass film. Because the SiO 2  film 8 has a low surface potential inclination in the guardring portion, it can be used for the surface protective film, the filmthickness is made thick in the other high potential inclination portions and a high reliability can be sustained by a glass film useful for protecting of the surface even if a plastic seal is performed.
