Title: Positioning controller for magnetic head
Inventor: YAEGASHI KIMIHARU
IPC: G11B21/10
Filed: 1985-11-30
Abstract: PURPOSE:To shorten the movement time of a controller side by switching and using a speed signal based upon the current integral value of a carriage motor and a speed signal obtained by differentiating a position signal as specified and bringing a carriage under servocontrol. CONSTITUTION:When the position signal from a position detecting circuit 17 is switched, analog switches 13 and 22 are turned on and off respectively and a speed control signal from a current integration circuit 21 which integrates the current of the motor 15 for driving the carriage 16 is supplied to a feedback circuit. Then, when a transient state is entered, an analog switch 12 is also turned on to correct the speed signal and performs feedback control, and when a stable state is entered, only the switch 12 is turned on to perform position control under the feedback control of the speed signal through a detector 17 and a differentiation circuit 18. This constitution eliminates the need to set the speed to zero during position signal switching and a magnetic head is moved after the certain number of a pulses are received without receiving all pulses corresponding to the number of target cylinders. Consequently, the apparent movement time of the controller side is shortened and the processing time is shortened.

Title: Reverse recovery transient voltage suppressor circuit of thyristor
Inventor: SAOTOME HIDEO
IPC: H02M1/00
Filed: 1984-12-22
Abstract: PURPOSE:To suppress the reverse recovery transient voltage at turning OFF time of a thyristor by connecting an anti-parallel circuit of a series circuit of a saturable reactor and a diode and a series circuit of a capacitor and a diode in series with the thyristor. CONSTITUTION:If a switch SW22 is closed when a load current I0 flows through a communication reactor 20, a diode D32, a saturable reactor 30, and a thyristor 10, a thyristor current (i) starts reducing, and inserts in the direction. When the inductance LS of the reactor 30 when the current (i) is reduced until the saturation of the reactor 30 is released is sufficiently larger than the inductance L of the reactor 20, the both terminal voltages vL, vLS' of the reactors 20, 30 become vLapprox.=0, vLSapprox.=-E, and the voltage vC of the capacitor C becomes vCapprox.=E. Accordingly, after the thyristor 10 is turned OFF, the current (i) is not almost flowed. Thus, the reverse recovery transient voltage when the thyristor 10 is turned OFF can be effectively suppressed.

Filed: 1984-12-21
Abstract: PURPOSE:To measure the concentration of turbid substances in a sample liquid accurately by providing a temperature correction circuit which inputs a transmitting element and a received signal outputted from a receiving element in common to output a temperature correction signal. CONSTITUTION:When a transmitting signal for excitation driving a transmitting element 8 is applied to a first trigger pulse TP generator 28, an RSFF 32 is set to output a H signal. When a received signal is applied to a second TP generator 30 from a receiving element 10, and FF32 is reset and the signal output is inverted to L. A signal is outputted from the FF32 with the pulse width corresponding to the propagation time of an ultrasonic wave propagating through a sample liquid 4. As the pulse width of the output signal of the FF32 is a function of temperature, changes in the temperature of the sample liquid 4 causes variations in the pulse width. The output signal of the FF32 is converted into a DC voltage corresponding to the pulse width with a pulse width-voltage converter 34. Furthermore, the results are inputted into a multiplier 36, where it is multiplied by a coefficient of a fixed ratio to be converter into a temperature correction signal. An adder 38 adds the temperature correction signal from the amplification circuit 36 to the output concentration signal of an inverse logarithm amplifier 24 to correct the concentration signal in terms of temperature.
