Filed: 1983-06-23
Abstract: PURPOSE:To reduce man-hour required for making a failure diagnosis or remote maintenance by sending out a required maintenance command at a prescribed time and automatically performing recording and statistical processing on a returned executed result. CONSTITUTION:When a diagnostician starts a diagnosis after setting the wake- up time of each diagnostic command generating section 11 from an operating section 12 in a controlling procedure setting section 13 in advance, the controlling procedure setting section 13 wakes up required one of the diagnostic command generating sections 11 at the prescribed time set in advance. Upon receiving a diagnostic command from the generating section 11, an electronic exchange 1 executes a prescribed diagnostic process and transmits the diagnosed information to the information receiving section 14 of an input-output device for maintenance, through which the information is stored in a storage section 15. A diagnosed information analyzing section 16 executes diagnosis analyzing process based on the diagnosed information stored in the storage section 15 and stores a suspected troubled part in the storage section 15. An output controlling section 17 extracts the suspected trouble part from the storage section 15 and outputs and displays it to a display 18 or printer 19.

Abstract: PURPOSE:To maintain oil in a compressor at the restarting of said compressor and prevent the loss of a mechanical part by installing a detection means which detects an operation status of the compressor, and an expansion valve control means which extends a throttling variable of the expansion valve which controls a circulation volume of refrigerant when the compressor is in suspension. CONSTITUTION:A compressor operation status control means 3 is adapted to input a signal transmitted from a compressor operation status detection means 2, judges the operation halt of a compressor 1 while an expansion valve control means 4 inputs a signal transmitted from a compressor operation status discrimination means 2 and controls a throttling variable of an expansion valve 5 so as to full open the valve during the suspension of the compressor. A compressor operation time memory discrimination means 6 counts the operation time of the compressor, generates a full open signal of the expansion valve 5 during the suspension of the compressor only when it exceeds a specified time while an expansion valve full open time memory discrimination means 7 counts a full open time of the expansion valve 5 during the suspension of the compressor. When it comes to a specified time, the means 7 generates a signal which turns the throttling variable of the expansion valve into a specified volume. A sensor input discrimination means 9 inputs the suction pressure of the compressor 1 and a signal from a discharge pressure sensor 8 and outputs a signal which directs an expansion valve 4 to open full during the suspension of the compressor when there exists a differential pressure of more than specified value.

Title: Radiation detector
Inventor: YOSHIDA YUZO
IPC: A61B6/03
Filed: 1989-05-08
Abstract: PURPOSE:To widen sensing areas and photograph the whole image by varying the sensing areas of respective detecting elements, which constitute a detection unit, to incident radiation according to the size of a body to be photographed. CONSTITUTION:When each detecting element 15 is rotated by an angle theta so as to vary aperture width, the detecting element 15 increases in element-to- element distance on a slide line at the time of the rotation, so the detecting elements are moved in parallel along the arcuate groove 22 of a support frame 21. Therefore, when theta = 30 deg. and d1 = 1mm, d2 = 1.15mm and when the total number of channels of the detector is 500, 1.15 X 500 = 757mm, so that the photographable area at the position of the detector is widened as compared with the initial state. Therefore, when a large body to be inspected is photographed, the sensing areas are widened and the whole image can be photographed.

Title: Electrophotographic sensitive body
Inventor: HAGA KOICHI
IPC: G03G5/08
Filed: 1985-05-28
Abstract: PURPOSE:To enhance adhesion between an amorphous silicon layer and a substrate by forming a porous Al2O3 layer between the substrate and the amorphous layer and using a material made of silicide as a pore sealing agent at the time of treatment of the pores of the porous layer. CONSTITUTION:The porous Al2O3 layer 2 is formed on a substrate 1 and the pores of the layer 2 is sealed with the silicide sealing agent 2'. When needed, the silicide is removed to disclose the surface of the substrate 1 by etching or the like, and the amorphous silicon a-Si layer 3 is deposited. Since H2O chemically bonded in the Al2O3 layer 2 exists in an extremely minute amount and an amount of H2O to be diffused into the a-Si layer 3 is almost negligible, the characteristics as the electrophotographic sensitive body are stable for a long period, thus permitting adhesion between the substrate 1 and the a-Si layer 3 to be remarkably enhanced by the anchor effect of the silicide intruding into the pores.
