Title: Method for driving motor
Inventor: FUJII MASAHIRO
IPC: H04B7/26
Filed: 1990-02-26
Abstract: PURPOSE:To minimize weight and to make the motor compact in size by providing a voltage control circuit varying a voltage applied to the motor at a certain period and assisting the change in the speed of revolution of the motor to amplify the vibration caused by the rotation of the weight placed eccentrically. CONSTITUTION:The resistance of a resistor in a voltage control circuit 1 is varied periodically by using an external signal through a control terminal 1A to vary a voltage applied to the motor 4 as shown in waveform diagram in the Figure 3(a) with respect to time, thereby varying the speed of revolution and the angle of rotation of the motor. A voltage change in the motor for a period longer than that of a rotating angle 360 deg. (one period) is applied to the motor to allow the vibration caused by the drive of the weight placed eccentrically to be amplified.

Title: Gain variable amplifier
Inventor: HAYASHI SHIGEYOSHI
IPC: H03G1/00
Filed: 1983-03-19
Abstract: PURPOSE:To drive a gain variable amplifier at a low voltage by adjusting a value of a constant current applied to a differential amplifier whose amplification gain is adjusted depending on the increase/decrease of an operating current in response to a control voltage. CONSTITUTION:An intermediate frequency signal from terminals 8, 20 is given to a base of a couple of transistors (TRs) 8, 10 of the differential amplifier 2. The operating current of the amplifier 2 is given by a TR28 of a constant current circuit 4, the amplification gain of the amplifier 2 is set, and an input signal is amplified based on the amplification gain and extracted from output terminals 22, 24. When the amplified output is detected and given to a control input terminal 54 as a gain control voltage Vagc, a current of a TR50 of a current control circuit 6 is absorbed into a TR42 by the current mirror effect. As a result, a synthesized current of the current I of a constant current source 32 and a current of the TR24 flows to a TR30 of the circuit 4 and the synthesized current adjusts the current of a TR28 by using the current mirror effect. Thus, a prescribed proportional relation is kept for the gain of the circuit 2 and the voltage Vagc and the AGC operation is performed by a low voltage.

Title: Motor speed control method and motor speed control equipment
Inventor: IMAI YUUGO
IPC: H02P29/00
Filed: 1996-03-04
Abstract: PROBLEM TO BE SOLVED: To provide a control method provided with a current compensation means which can avoid the influence of external disturbance upon motor speed without depending on the gain value of a current amplifier. SOLUTION: This method controls the speed of a motor by using a control equipment having a current control loop for controlling an armature current IM as a minor loop, to a speed control loop for controlling a motor speed. The estimation value of motor torque is obtained by multiplying the armature current IM of a motor and the nominal value KTn of a torque constant KT. The inverse model of integration characteristics of the moment of inertia JM of the armature 14 of the motor is simulated and a differentiator 23 is constituted. From the above estimation value of the motor torque, the estimation value of the motor torque obtained by differentiating a motor speed detection value by using the differentiator 23 is reduced, thereby obtaining the estimation value Td0 of external disturbance torque.  By using a proportional differentiator 4 constituted by simulating the inverse model of a current loop and an amplifier 3 having a gain equal to the inverse of the nominal value of a motor torque constant, specified operation is applied to the estimation value Td0 of the external disturbance torque. The obtained value is adopted as the compensation value ΔIC of a current command value.

Title: Covering and heat insulating material for molten metal
Inventor: TAKASHIMA TADASHI
IPC: C22B9/00
Filed: 1979-04-19
Abstract: PURPOSE:To enable the prevention of cooling and oxidation of molten metal by using a calcined product or soot ash having a specific particle size which ia obtainable through high-temperature incineration of the waste sludge from paper making process of paper and pulp. CONSTITUTION:The waste sludge discharged from paper making process of paper and pulp is fired at about 600-1,000 deg.C (about 300-1,000 deg.C by conventional methods). The resulted calcined product or soot ash of <20mm grain size is used as the heat insulating material for a molten metal. The soot of the ash obtainable by this method consists essentially of coke material and is hardly combustible because it is produced by a quick heating process. Hence, if this is added to the surface of the molten metal to form a covering layer, the covering layer maintains difficult solubility to retard the consumption of C for a long time and this makes possible to maintenance the molten metal surface in a reducing atmosphere for a long period of time.

Title: Image reproducing device
Inventor: HIROTA YOSHIHIKO
IPC: G03G15/01
Filed: 1995-03-07
Abstract: PURPOSE: To provide a device reproducing a single color accurately as intended by allowing an operator to select and set a desired mixing ratio of R, G, B so as to control gradation data for single color reproduction. CONSTITUTION: The copying operation of a full color copying machine is set by selecting an automatic color selection(ACS) mode or any of four kinds of original modes by an operation panel 154. When the ACS mode is selected, any of the four original modes is automatically selected by the decision of an original type through preliminary scanning. When an original is judged to be a black/white original, either the single color standard mode or the photographic mode is automatically selected. When the single color standard mode/the photographic mode is selected, the operation menu changes into a single color mode operation menu and a mixing ratio of R, G, B data deciding the single color gradation data as an original parameter is set manually. Thus, the operator easily sets a desired mixing ratio and a monochromatic copy without a sense of incongruity is obtained.
