Title: Magnetic head driving controller for magnetic recording and reproducing device
Inventor: OGAWA TOMIHISA
IPC: G11B21/10
Filed: 1989-04-04
Abstract: PURPOSE:To execute the movement to a target position at high speed by executing a positioning control mode by a finite time setting control system in an intermediate stage for driving a magnetic head to a target position by a sevo- system. CONSTITUTION:At a first stage for driving a head, an analog switch (A/S) 34 is turned on in a speed control mode and a speed error signal is sent to a VCM driver 24. When some time point elapses, a CPU 32 turns on an A/S 35 and detects a position of an actuator 15 from a position error signal from an ADC 31 and a speed signal estimated therefrom or a speed signal from an ADC 30. Subsequently, a result of operation for executing a positioning control mode by a finite time setting control system is outputted to a DAC 36, and the position error signal is sent to the driver 24. At the time of reaching the next time point, an A/S 33 is turned on, and the head reaches a target position in a conventional positioning control mode. In such a way, the driving controller which can position the head at high speed is obtained.

Title: Gate bias circuit for fet
Inventor: SHIBATA JUNICHI
IPC: H01L27/04
Filed: 1996-04-08
Abstract: PROBLEM TO BE SOLVED: To reduce the adjustment man-hours of the bias voltage of an amplifier employing a FET. SOLUTION: A signal via an input terminal 1 and an impedance matching circuit 2 is given to the gate G of a FET 11. The gate bias voltage of the FET 11 is determined by a bias adjustment circuit 12 and a bias resistor 3 according to the voltage from a gate bias application terminal 4 and the FET 11 amplifies the signal at an operating point depending thereon. The bias adjustment circuit 12 is formed in a FET chip 10 together with the FET 11 and is a resistor whose resistance is changed proportionally to the pinch-off voltage of the FET 11. Even when the pinch-off voltage of the FET 11 is changed, the resistance of the bias adjustment circuit 12 changes with the change in the pinch-off voltage so as to allow the gate G and a source S of the FET 11 to receive a voltage proportional to the pinch-off voltage at all times thereby allowing the FET 11 to be in operation at the same operating point.

Filed: 1980-06-24
Abstract: PURPOSE: To use effectively a monolithic type catalyst structure for cleaning automobile exhaust by continuously changing the Pt/Rh ratio of the catalyst from the inlet side of the exhaust to the discharge side.  
     CONSTITUTION: The Pt/Rh ratio of a monolithic type Pt-Rh ternary catalyst structure for cleaning automobile exhaust is continuously changed by adhering Rh high- densely and Pt low-densely on the exhaust inlet side of the honeycomb-structure support 3A of the catalyst structure and also adhering Rh low-densely and Pt high- densely on the discharge side of the catalyst support 3A. The honeycomb structure support 3A is set in a Pt-impregnating tank 4, an operation involving pushing up a Pt-containing liquid L up to the tank 4 by compressed air and soon forcing it down to a supplying portion 5 by an ejector is repeated until a desired adhesion density of Pt is obtained, and then support 3A is taken out and dried. Then, the exhaust inlet side (a) and the discharge side (b) of the support 3A is reversed and then subjected to the same operation using Rh-containing liquid instead of Pt-containing liquid. Thus, a catalyst structure having Pt/Rh ratio continuously changing in the flow direction of the exhaust can be obtained.
