Patent JP-S624926-A (JP)
Title: Shaft joint of rotary machine
Inventor: ASAZU SEIICHI
IPC: F16B35/00
Filed: 1985-06-28
Abstract: PURPOSE:To prevent a slip of a joint area, by a method wherein a sleeve, longer than the length in the direction of the axis of a pair of shaft joint flanges and having plural circumferential grooves formed in an inner and an outer peripheral surface and alternately in a longitudinal direction, is situated in a gap between the bolt holes of the shaft joint flanges and the outer periphery of a fastening bolt. CONSTITUTION:A sleeve 10 is disposed in a gap 9 between bolt holes 4 and 5 of a pair of shaft joint flanges 1 and 2 and the outer periphery of a fastening bolt 6. Since the sleeve 10 is longer given amount than a total of lengths of the bolt holes 4 and 5, the sleeve is resiliently deformed by fastening of fastening nuts 7 and 8 and is forced into pressure contact with the fastening bolt 6 and the bolt holes 4 and 5. In which case, circumferential grooves 12 and 13 may be formed in the outer and the inner peripheral surface of the sleeve 11 alternately in an axial direction. Thus, a clearance 9, increased by fastening of the fastening nuts 7 and 8, is absorbed through deformation of the sleeve 10 or 11, and this enables prevention of a slip of a joint area.

Filed: 1981-09-11
Abstract: PURPOSE:To provide a compact motor-operated device which detaches and conveyes a wafer from a wafer cartridge, reduces a shock produced when detaching and conveying the wafer, and improves a cleaning property. CONSTITUTION:A wafer cartridge 3 is lowered in a pitch-feed manner by an elevator unit 1.

Abstract: PURPOSE:To control an electrostatically charged potential without receiving the influence of variance in a photosensitive body and without using any special device such as an electrometer by providing a detecting electrode on the down stream side of the coronode of a charger, detecting the current flowing in a constant voltage element and controlling a high voltage for charge. CONSTITUTION:The high voltage from a high voltage power source 5 is impressed to the coronode 2 of a charger 1, by which a photosensitive body 6 is charged. The value near the final value of the charged potential is detected with a detecting electrode 4 provided on the down stream of the coronode 2. The current corresponding to the charged potential of the photosensitive body is supplied via a constant voltage element 7 connecting to the electrode 4 and a resistor 8 to the comparator circuit 9 of the power source 5 and is compared with set current. The high voltage from the power source 5 is controlled and the charged potential of the photosensitive body 6 is feedback-controlled. The charged potential is thus controlled in accordance with the value near the final value of the charged potential which is less influenced by the variance in the photosensitive body without using any special device such as an electrometer or the like.

Title: Apparatus for detecting distance between vehicles
Inventor: ASAYAMA YOSHIAKI
IPC: G06T7/00
Filed: 1995-06-09
Abstract: PURPOSE: To stably detect a distance of vehicles even when a preceding vehicle comes close, and prevent an increase of a processing time, by setting an image of a predetermined part in a window where an image of the preceding vehicle is tracked to be a reference image for detecting the distance of vehicles when a detected distance value is smaller than a predetermined value. CONSTITUTION: When a distance between vehicles is reduced, an image of a preceding vehicle in a display screen 11 becomes large and a tracking window is always changed to a size surrounding the image of the preceding vehicle in accordance with a detected value by a distance detection means. However, the image of the preceding vehicle photographed by a lower image sensor 3 comes out of the screen, making it difficult to detect an image agreeing with the image in the tracking window surrounding an image of the preceding vehicle photographed by an upper image sensor 4 from an image in a memory 8. Therefore, if the detected distance value is smaller than a predetermined value, a distance-measuring window for detecting the distance is set based on an image in a memory 9 at a predetermined part in the window tracking the image of the preceding vehicle and, an image in the distance-measuring window is set as a refereence image to detect the distance between the vehicles.
