Abstract: PURPOSE:To form a gate electrode asymmetrically in a recess structure by simple steps by forming an insulating film partly covering an n<+> type conductive layer and an insulating film covering the entirety, then etching together with side etching to proceed underneath a resist layer, and forming an offset recess structure. CONSTITUTION:An insulating film 5a is formed on an ohmic electrode 4 and a channel layer 3, the film 5a of a position corresponding to a gate electrode is removed, and an insulating film 5b is formed thereon. Then, a substrate 1 loaded with a patterned resist layer 6 is reactive ion etched. In this case, the film 5b is etched at a region where the layer 6 is defective, then the film 5a is etched, and the films 5a, 5b are proceeded by side etching underneath the layer 6. With the films 5a, 5b as masks the layers 3, 2 are etched, and a gate electrode 7 is eventually formed.

Title: Demodulating device of chrominance signal
Inventor: KASAGI YOSHITAKA
IPC: H04N9/64
Filed: 1982-06-04
Abstract: PURPOSE:To simplify the circuit and to reduce the cost, by constituting the titled device so that the signal gain of the phase detecting circuit section does not change at the time of system switching and commonly using the element as much as possible for processing signals of each system. CONSTITUTION:When the system processes the PAL type television signals, a 1H-delayed chroma signal which is obtained by delaying a chrominance signal by 1H and a direct chrominance signal which is not delayed are matrix processed. By this matrix processing, components (B-Y) and (R-Y) are separated from each other and inputted into a (B-Y) demodulator 76 and (R-Y) demodulator 77, respectively. On the other hand, when the system processes the NTSC type television signals, an operation switch 74 is turned on and a 1H-delayed chrominance signal on a delay input lines 75a is earthed. A signal outputted from a PAL matrix circuit 75 is demodulated at the (B-Y) demodulator 76, the (R-Y) demodulator 77 and a (G-Y) demodulator 78.

Title: Controller for thyristor motor
Inventor: OKUYAMA TOSHIAKI
IPC: H02P6/20
Filed: 1978-08-09
Abstract: PURPOSE: To reduce the ripple of torque of a thyristor motor when it rotates slowly, by adjusting the control advancement angle depending on the level of the current of the motor  
     CONSTITUTION: An automatic pulse phase shifter 8 regulates the control delay angle of a cyclone converter 1 depending on the difference between the output signal of a current detector 6 and that of a speed deviation amplifier 5 which amplifies the deviation of a speed detection signal from a speed command signal. A speed discrimination circuit 12 discriminates whether the revolution speed of the motor 2 is high or low. A function generator 13 selects a characteristic corresponding to the output of the speed discrimination circuit 12 and generates a phase control signal corresponding to the input current to the cyclone converter 1. The automatic pulse phase shifter 10 compares the phase control signal with a position signal to regulate the control advancement angle of the cyclone converter 1 depending on the armature current of the motor even if the motor rotates slowly. The terminal voltage and the armature current of the motor are thus set at the same phase. This results in reducing the ripple of torque of the motor when the motor rotates slowly.
