IPC: G01R33/32
Filed: 1990-04-27
Abstract: PURPOSE:To achieve a higher resolving power by providing a noise remover comprising a memory element having a plurality of individual memories in a transmission circuit for a resonance signal or in a connection circuit for transmitting control signals to read and transmit memory data of the individual memories simultaneously by a reading signal having a time difference from a read-in signal. CONSTITUTION:Resonance signals sampled are stored into individual memories 21a, 21b,... and 21n by clock signals WRa, WRb,... and WRn for reading and noises carried on the resonance signal are frozen into the individual memories. Then the resonance signals stored respectively in the individual memories 21a-21n are called simultaneously by a short reading clock pulse RD to be outputted upon the end of the clock signals for reading to be transmitted to a computer 7. This makes available a function of freezing noises on the individual memories to block propagation of the noises and a function of suppressing phase differences by the synchronizion of a signal output.

Title: Servo control method
Inventor: NISHI YOUZOU
IPC: G05B19/19
Filed: 1984-06-04
Abstract: PURPOSE:To attain the proper servo control over an entire working area by varying the gain for compensation of each type of characteristics which is applied to a control system according to the current value of a motor-driven actuator that is controlled by the control system. CONSTITUTION:Both the old target position data e0'(t) and the speed command data v0(t) on an action shaft are read out of a memory 1. Then the target position data e0(t) is calculated 13, and a position deviation is calculated 14 from the data e0(t) and the present position data e(t) given from a position detector 2. The data e(t) is differentiated 15 for calculation of the revolving speed v(t) of the action shaft, and a deviation is calculated between the speed v(t) and the speed command data v0(t). The command acceleration alpha0(t) is calculated 17 together with the acceleration alpha(t) of each shaft. Then a deviation is obtained 19 between both said accelerations. The amount of integration is calculated 20 based on a position deviation. Then a gain constant is multiplied by each deviation for calculation of each compensation output. The change of the load state is shown as a change of the current flowing to a servomotor 28. Thus the gain of each characteristic compensation is changed according to the change of said current.

Abstract: PURPOSE:To attain complete erasure of an optical recording medium over the entire range by increasing always an erasure optical beam irradiating section than a recording optical beam irradiating section. CONSTITUTION:An erasure optical beam irradiation start position 7 is controlled to come earlier than the recording optical beam irradiation start position 8 by a half r/2 of the major radius of the erasure optical spot M or over and the erasure optical beam irradiation end position 9 is controlled always to come later than the recording optical beam irradiation end position 10 by r/2 or over. Then the erasure optical beam irradiation section is always larger than the recording optical beam irradiation section.

Abstract: PURPOSE:To maintain the shoe clearance at a constant value and the stroke constant, by supplying a hydraulic liquid to a wheel cylinder when the shoe clearance has become above a preset value. CONSTITUTION:Springs 7, 8 push respective pistons 3, 4 rearward. The spring 7 is greater than the spring 8 when the shoe clearance is adjusted in a prescribed range, and on the other hand when the shoe clearance exceeds the prescribed value, the spring 8 is made greater than the spring 7 by that increment. In a bore 16 of the piston 3, a check valve 12 is slidably fitted. The valve 12 is pushed rearward by a spring 14, but when the piston is restored, the valve 12 abuts on a stopper 17 and is opened. In a passage 25 connecting a liquid tank 21 and an auxiliry chamber 6 is provided a check valve 23 so that a liquid can flow only from the liquid tank 21 to the chamber 6. When the brake is applied in the state where the clearance has exceeded the prescribed value, the tension of the spring 8 becomes greater than that of the spring 7, and therefore when the brake is released, the piston 4 is quickly restored, a negative pressure is produced in the chamber 6, and the liquid is supplied from the tank 21.

Title: Cutting and bonding device for decorative-board tape terminal section for veneer
Inventor: RUDEI SUPERUDAASU
IPC: B27D5/00
Filed: 1989-05-10
Abstract: PURPOSE: To obtain a time and energy saving by using a pressure beam which is movable with respect to a fixed ground plate and held in a bridge which is vertically displaceable in order to apply a necessary pressure on extremities of decorative sheet tapes and an adhesive tape. CONSTITUTION: Two pairs of under knives 3, 4 are mounted on a fixed ground plate 1. Decorative sheet tapes 5, 5' for veneer are guided thereon and cut according to a desired saw tooth pattern. Upper knives 6, 7 cooperate with the under knives 3, 4. A hammer 13 of a pneumatic press exerts a necessary pressure on a pressure beam 10 in order to connect an adhesive tape by means of pressure and heat to the saw tooth shaped extremities of the tapes. The pressure is exerted by a pneumatic cylinder 28. The cylinder only has to be displaced over a very short distance during the pressurizing action, which signifies a sensible saving when the necessary time and energy for realizing that pressure build-up is taken into account.
