Title: Fm sound recording signal reproducing circuit for vtr
Inventor: TAKAHASHI AKIRA
IPC: G11B5/027
Filed: 1988-04-15
Abstract: PURPOSE:To prevent the deterioration of a voice at the time of the high-speed reproduction of an FM voice recording by executing a changeover to a voltage lower than a DO comparing voltage at the time of reproducing the FM voice recording at a high speed in an FM voice demodulating circuit to interrupt a sound demodulated signal only in the omission period of the signal and to correct the signal. CONSTITUTION:When an omission is generated in an FM reproducing signal A, a level with an envelope signal extracted through a limiter amplifier 1 by a filter 2c in a DO detecting circuit 2 is made lower than a DO comparing voltage V01 in the omitted part. Then, the circuit 2 generates a DO detecting pulse D, a permanent-closed switch SW of a DO correcting circuit 3 interrupts a sound demodulated signal B only in such a period, and simultaneously, a signal level just before the signal B is supplied from a capacitor C2 to an audio amplifier 5. Thus, the interruption of the switch SW is canceled before the discharge of the capacitor C2 is completed, and the signal B is fed into the amplifier 5 again. Thus, for a sound signal E outputted from the amplifier 5, the omitted part of the signal can be corrected.

Title: Thyristor valve
Inventor: OTSUKA KYOICHI
IPC: H02M1/088
Filed: 1993-04-21
Abstract: PURPOSE:To secure the antiseismic and insulating abilities of a thyristor valve by press-fitting reinforcing members composed of insulating members having cruciform horizontal cross sections which are about two times or less than three times larger than the height of a flange to the insides of end sections of insulating columns. CONSTITUTION:Reinforcing pieces 7a are press-fitted to the insides of insulating columns 2 of the title valve and, when the valve is excited by seismic waves, etc., the whole body of the valve is deformed in a low-order mode of vibration, but the deformation occurs in the X or Y direction in many cases. When the whole body of the valve is deformed, the insulating columns 2 are bent, but, since the reinforcing members 7 having cruciform cross sections are press-fitted to the insides of the columns 2 in the X or Y direction of the valve, the deformation of the valve in cross section is suppressed even when bending moments are applied to the columns 2 due to the exciting force. As a result, the size of this thyristor valve can be reduced while the antiseismic and insulating abilities of the valve are maintained at prescribed levels, because the dropping of the flexural rigidity of the columns 2 is prevented and the antiseismic characteristic of the valve is improved.
