Filed: 1982-07-15
Abstract: PURPOSE:To obtain the maximum braking efficiency according to a road surface condition, by varying a pulse width of a pressure reduction signal in accordance with braking hydraulic pressure applicable at the time when wheels are locked. CONSTITUTION:A braking hydraulic pressure signal from a control hydraulic pressure sensor 9 is stored in a sample holding circuit 10 based on a signal from a wheel locking signal generating circuit 8, and hydraulic pressure proportional voltage V11 based on the stored signal becomes applicable by a voltage generating circuit 11. Saw-tooth voltage V12 is generated by a reference wave shape generating circuit 12, an output V13 having a pulse width corresponding to hydraulic pressure is generated by a comparison circuit 13 by comparing the voltage V12 with the voltage V11 and a pressure reduction signal V14 becomes applicable by a signal generating circuit 14. As a pressure reducing period of time varies according to braking hydraulic pressure applicable at the time when the wheel is locked, control efficiency is improved by reducing pressure for a short period of time on a road whose friction coefficient is high and for a long period of time on a road whose friction coefficient is low.

As a result, the output of the limiter regulator 2k is made active, and frequency is risen, and cross current is reduced.

Abstract: PURPOSE:To make it possible to manufacture a stable and high-quality molding excellent in properties of mixing with coloring agent or assistant with lower manpower and less costs, by forming a recessed part in the surface of an uncolored thermoplastic resin pellet, wherein the depth of said recessed part is larger than the width of said surface, mixing this pellet with powder coloring agent and agitating this mixture, forcing the coloring agent into said recessed part and then heating to fuse this pellet.

Title: Quantity regulator
Inventor: BENO PARETSUTA
IPC: B01L99/00
Filed: 1980-09-08
Abstract: The metering apparatus for small volumes of liquid in the milliliter and microliter range comprises a piston/cylinder system driven by a direct-current motor. The piston stroke is measured by means of an optical path-length measuring system. For this purpose, a slide-rule pulse scale provided with a regular line grid is affixed to the piston. The light from a light transmitter passes through the slide-rule pulse scale and a stationary scanning plate which likewise is provided with a regular line grid, and to a light receiver. The pulses of the light receiver are digitalized in a pulse conditioning circuit and fed to a counter adapted to be preset by means of a coding switch. The counter position acts upon a braking and rotative-speed regulating circuit in such a way that regardless of the preset desired value of the rotative speed the speed of rotation of the motor is reduced to a small value as the final value is approached. As soon as the preset volume has been metered and the counter has reached the zero position, the motor is brought to a dead stop through a motor-control logic circuit with the aid of a reverse voltage. During the stopping process the no-load voltage of the motor is measured by means of a zero-voltage comparator at regular intervals. A pulse monitoring circuit serves to measure and regulate the piston-stroke speed and to turn off the motor in case of a mechanical defect. Motor and electronic systems are supplied with current from dry cells or storage batteries, a power supply being optionally provided to charge them.

Filed: 1981-08-06
Abstract: PURPOSE:To obtain a 2-color image by use of the same developing machine, by using a  mixed developer consisting of an insulating magnetic toner, and a high resistance  magnetic toner having photoconductivity and a color which is different from the  former, and selectively charging an electrostatic latent image formed on the surface of  a photosensitive body. CONSTITUTION:A developing device 20 is formed by covering the outside circumference  of a roller-like magnet 13 with an electrically conductive carrier 14, and placing a  developing layer control plate 22, a developer charging charger 15 and a developer  exposure source 16. A black insulating magnetic toner TB(>=10<15>OMEGAcm) is mixed with a  red toner TR having photoconductivity and high resistance magnetism (dark resistance  10<8>-10<11>OMEGAcm), by which a magnetic toner De is obtained. It is magnetically adsorbed  like one layer by the control plate 22, and is charged 15 and is exposed 16. The black TB is charged, but the red TR is not charged. On a photosensitive body surface 11a, an  electromagnetic latent image of an original is formed, and at first, the black TB is  transferred. Subsequently, a bias electric power supply 18 is applied to a photosensitive  body substrate 11a, and the red TR is transferred to the latent image which has passed  through a red light absorbing filter 17, by which a copied image having 2 colors is  obtained.

Title: Position detection device for brushless dc motor using time-difference method without hall-effect device
Inventor: JIYON SHII DANFUIIRUDO
IPC: H02P6/18
Filed: 1991-05-28
Abstract: PURPOSE: To drive a motor in a correct direction by detecting a code of time difference at a induced voltage rising time after each phase is energized by a pulse, and establishing a table for surely determining a rotor position with respect to each phase of the motor. CONSTITUTION: A timer 22 is drive after a positive current is fed to each phase of a motor 14 by a pulse generator 10. The positive current is fed until a voltage of a detecting resistor 16 becomes larger than a reference voltage 20 of a comparator 18, and the time required is stored in a memory 24. On the other hand, the same phase is energized with a negative current, and the comparator 18 is triggered, when the voltage of the detection resistor 16 goes over the reference voltage 20. Then, the retriggerring is carried out again by a signal of the timer 22 or the pulse generator 10, and the current is stopped by the trigger of the comparator 22. The length of signal is stored in a memory 26, and the two time differences are substrated from each other. The code is stored in a memory position 30.  This process is repeated for each winding, and memory positions 31 and 32 are filled with the code values. These code values instruct a torque-up table 34 and show a sequence of phase excitation.

Title: Floating type fluid-operating actuator
Inventor: RARII ERU FUIIRUDO
IPC: F16K31/06
Filed: 1992-05-15
Abstract: PURPOSE: To provide a fluid-operated actuator capable of selectively advancing, retracting or holding in a predetermined position when power is applied to a system, fully retracting upon power failure; and being controlled by an extremely simple circuitry. CONSTITUTION: A hydraulic actuator 10 is provided with a pump 23 which is driven by an electric motor 25 and a piston 17 advanced by a hydraulic oil sucked from a low pressure chamber 15 of a cylinder 14 to a high pressure chamber 16, and the actuator is controlled by a floating single pole double throw switch. An exhaust valve 30 in the piston 17 is held in a closed position when a coil is energized, thus enabling pressurization of the high pressure chamber 16 of the cylinder 14. When a second coil is energized, a magnetic field of the first coil is negated and the exhaust valve 30 is opened, therefore the hydraulic oil is exhausted from the high pressure chamber 16 to the low pressure chamber 15, thus retracting the piston 17.  When currents to the pump motor 25 and the second coil are block off, the exhaust valve 30 is kept in the closed position, and therefore the piston 17 remains in a commanded position. When a current to the actuator 10 is blocked off, the piston 17 is automatically shifted to its fully retracted position.
