Title: Power seat device for automobile
Inventor: UMEDA KAORU
IPC: B60N2/22
Filed: 1986-06-26
Abstract: PURPOSE:To prevent an electric power source on vehicle from being wasted by providing a circuit controlling current to a motor whereby controlling the current consumption by the motor to be equal to or less than a certain value. CONSTITUTION:When a switching circuit 502 is turned on a relay coil (611) side, current flows from an elective power source terminal B to a power source terminal E through a diode 615. As a result, the transistor 634 of a breaker circuit 630 is energized for actuating a relay contact 611' correspondingly. Said actuation caused current to flow from the power source terminal B to the power source terminal E through the transistor 621 of a current limiting circuit 620 for starting a motor 303. In this case, the starting current of the motor 303 is kept to a value equal to or less than a certain value by the current limiting circuit 620. Owing to this constitution, as the motor 303 can be used in a range of high efficiency there is no need for use of a great capacity of motor and an electric power source on vehicle is not wasted. In addition, in case of over loading, the motor is de-energized for preventing a driving device from being destroyed.

Title: Apparatus for measuring vector quantity
Inventor: KITAYOSHI HITOSHI
IPC: G01R27/02
Filed: 1991-06-21
Abstract: PURPOSE:To reduce the load of a microprocessor and to shorten a measuring unit time by mounting a sequence controller controlling measurement. CONSTITUTION:A microprocessor (MP) supplies a defined command to a sequence controller (SC) to start measurement. The SC responds to the supplied command to operate an integrating section control circuit and an ADC in defined order. The ADC transmits the completion of A/D conversion to the MP as an interruption signal and the MP stores the data subjected to A/D conversion in the corresponding memory of the AD/ID outputted from the SC and transmits the completion of the taking-in of data to the SC. The SC confirms the completion of the taking-in of data of the previous time by the MP at the time of the completion of integration to start the next A/D conversion. As mentioned above, the control of measurement is entrusted to the SC and the MP issues a command for the SC to start measurement to perform the operation of the measured value of the previous time or the processing or display of data. As a result, a measuring unit time can be shortened.

Abstract: PURPOSE:To obtain a small-size printer applying printing to plain paper with high image quality, generating no environmental pollution and reduced in noise by using a photochromic material whose surface hydrophilicity is reversively changed by the irradiation with light as a latent image forming material. CONSTITUTION:A shutter 6 is opened after a latent image forming process is completed. A thin membrane surface is formed on a photochromic sheet l by the rotation of a drum 2 in a clockwise direction. The exposed part of the photochromic sheet 1 shows hydrophilicity but the flocculation force of ink is low because of low viscosity and the ink is in a state non-separable between the hydrophilic part and hydrophobic part on the photochromic sheet l. Next, an electric field is formed by a power supply 11 so as to go toward the photochromic sheet 1 and the drum 2 from a transfer roller 7, an electrode 9 and a fixing roller 10. The viscosity of the ink at this part changes to one hundred and several tens P. The ink increased in viscosity of a non-image part is peeled off by the transfer roller 7 and the ink bonded to the transfer roller 7 becomes low in viscosity in a region of a non-strong electric field to be separated.
