Title: Driver for electromagnetic actuator
Inventor: YAKURA TOSHIAKI
IPC: G05B11/26
Filed: 1985-08-29
Abstract: PURPOSE:To attain the linear control of an electromagnetic actuator by using a pulse signal having a desired duty ratio after performing the integration of deviation through a capacitor between said pulse signal and the detecting signal for the current flowing to the electromagnetic actuator. CONSTITUTION:An operational amplifier OP2 detects the current flowing to a linear solenoid 2. While a transistor (TR)3 which receives the pulse signal having a desired duty ratio from a CPU3 delivers the pulse signal obtained by inverting an input pulse signal. Then a capacitor C1 performs the the integration of deviation between the output of the OP2 and the output of the TR3. The both-terminal potential of the capacitor C1 is supplied to an operational amplifier OP1 and therefore the output of the OP1 is varied to H and L in accordance with the charging direction of the C1. Both the TR1 and TR2 are turned on and off by the output of the C1. Thus the solenoid 2 is turned on and off and driven by a constant current with the frequency equal to the duty frequency.

Title: Amplifier of semiconductor integrated circuit
Inventor: FUKUYAMA MAKOTO
IPC: H03F3/181
Filed: 1982-10-28
Abstract: PURPOSE:To reduce a transient sound at the switching of output/output stop of an amplifier by providing the titled circuit with the 2nd amplifier generating the same output DC voltage as the 1st amplifier for signal amplification in addition to the 1st amplifier. CONSTITUTION:Since the same amplifier 200' is connected to terminal Vc1 and Vc2, there is almost no output current voltage difference between the terminals Vc1 and Vc2 at the application of DC voltage. In case of AC operation, a signal inputted from a terminal VIN is amplified by resistors 37, 36 and the amplified signal is obtained from an output VOUT. Since an ALC circuit 50 to be used for detection and rectification is connected to an amplifier 200, the DC-like resistance of a transistor (TR) 49 becomes saturated resistance and is turned to the status connected with a resistor 23 in parallel. Said status means the variation of the output DC voltage VOUT, and the AC operation can be compendated in the same manner as the DC operation by the output DC voltage at the signal input (ALC operation) to a bias amplifier which is the 2nd amplifier 200'. Thus the transient sound due to a switch can be reduced and removed.

Title: System for recording three-level fm signal
Inventor: MATSUMURA OSAMU
IPC: G11B5/027
Filed: 1988-08-01
Abstract: PURPOSE:To improve a resolution by recording an FM signal with a waveform, in which a positive polarity pulse and a negative polarity pulse are alternately arranged, on a recording medium. CONSTITUTION:When an FM signal B modulated by a video signal A is counted to the frequency of a half by a counter driven with the fall edge, an FM signal C is obtained. In the same way, when the signal B is counted to the frequency of the half by the counter driven with a rise edge, an FM signal D is obtained, the FM signal with the waveform of E is obtained by superposing both waves of C and D, and it is recorded through a recording head onto a magnetic tape. Namely, since the FM signals C and D maintain a phase difference at 90 deg. mutually and they compensate the lacking of the opponent mutually, a beat disturbance can be improved by the waveform indicated by the E in which the waveforms of C and D are superposed. Thus, the resolution can be improved.
