Title: Semiconductor integrated circuit device
Inventor: SHIYUTOU HITOYOSHI
IPC: G05F1/56
Filed: 1982-07-05
Abstract: PURPOSE:To decrease the number of external parts, by incorporating an MOSFET which receives the voltage from a solar battery at its drain into a semiconductor IC together with a voltage comparator which compares the source voltage of the MOSFET with the reference voltage. CONSTITUTION:An MOSFETQ and a voltage comparator OP are incorporated into a semiconductor IC LSI which constitutes an electronic calculator that works on a solar battery E. The voltage -VE of the battery E is received at the drain of the MOSFETQ, and the source voltage -VDD of the FETQ is supplied to a noninverse input of the comparator OP to be compared with the reference voltage -Vref applied to the noninverse input. The output of this comparison is applied to the gate of the FETQ. Thus the impedance of the FETQ is controlled, and the voltage VDD is controlled so as to be coincident with the voltage Vref. Then a fixed level of voltage is supplied to a digital control circuit LOG. The display output of the LOG is transmitted to a liquid crystal display device LCD to perform a specific display. The clamp voltage can be set at an optional level by the voltage Vref.

Title: Method for controlling number of rotary displacement type compressor in operation
Inventor: SAWADA MASAO
IPC: F04C28/00
Filed: 1980-08-20
Abstract: PURPOSE: To save energy by a method wherein the number of the compressors counterbalanced to the consumed amount of compressed gas are put in operation.  
     CONSTITUTION: An unloader for the compressor is functioned to decrease the discharge volume from the compressor with the lowering of the suction pressure of the compressor C by throttling a suction throttle valve V. At first, all the unloaders of the compressors in operation out of a plurality of the compressors are functioned and as well as all the suction pressures of the compressors in operation are measured to be compared with the respective suction pressures at the rated operation of each of the compressors C and to calculate the respectiv marginal volumes Ai. When the overall marginal volume A, which integrates all the marginal volumes Ai of the compressors C in operation, exceeds the rated discharge volume of one compressor C, one compressor in operation is brought to stop. Or, when the marginal volume A decreases, one compressor is additonally brought to start in order to produce the compressed gas counterbalancing to the cosumed amount of compressed gas. An automatic start and stop discriminator circuit is provided to realize the method mentioned above by monitoring the overall marginal volume A and comparing the monitored volume A with the set upper limit value AH and the set lower limit value AL.

Abstract: PURPOSE: To brightly illuminate an image frame as a whole, even if an interchangeable lens having a different focal lenght is mounted, by equipping a camera body with detecting means for receiving the information of the focal length of a lens so that the imllumination angle of a strobo device may be automatically controlled in accordance with the information.  
     CONSTITUTION: If a taking lens having a short focal length is mounted in a lens mount 2, focal length detecting members 14 and 16 are shifted vertically of an image frame so that a lever 17 is turned counter-clockwise by the taper of the conical member 16. As a result, a wide panel 6 is protruded upward of a camera to a position, where a pin 30' and a protrusion 30' engage, until it is brought to a position where it covers the whole area of a controlling strobo unit 3. If, under this condition, the strobo emits a light, the resultant beam is scattered by a scattering plate 7 so that a wide covering power by a taking lens having a short focal length can be illuminated. Since, moreover, a scattering plate 8 is placed in front of the aperture 5 of the strobo unit, the covering power for control is enlarged so that the correct optical control can be accomplished even for the photography of the high coverling power
