Title: Electrophotographic receptor constituent
Inventor: MATSUURA KAZUO
IPC: G03G5/14
Filed: 1979-08-14
Abstract: PURPOSE: To prevent crystallization of an Se photoreceptor, its abrasion, rise of residual potential, deterioration of sensitivity, etc., and to enhance electrophotographic characteristics of the photoreceptor, by adding an aromatic polyamideimide layer on the surface of the Se or Se alloy layer.  
     CONSTITUTION: A layer of a polyamideimide chiefly composed of repeated units represented by the formula shown (Ar 1  is a trivalent aromatic group and Ar 2  is a divalent aromatic group) is formed as a protective layer on a photosensitive layer made of Se or Se alloy on a conductive substrate, thus permitting an electrophotographic receptor to prevent crystallization of the Se or Se alloy layer, its abrasion, and further unfavorable influence on its acceptable potential and its dark decay, and to raise sensitivity and to little raise residual potential.

Title: Welding method of thin sheet member
Inventor: KOMOTO HIROSHI
IPC: B23K26/00
Filed: 1994-05-18
Abstract: PURPOSE:To make visual inspection at the clearance of joined face easy so as to prevent defective laser welding from being performed by providing the notched part in a flange part in such structure that a folded back flange part is formed at the edge part of sheet and sandwiching the opposite sheet inbetween. CONSTITUTION:An inner panel 3 is tentatively held by sandwiching the edge part 3a of an opposite inner panel 3 between folded back flange parts 2a. A semicircular notched part 4 is provided in the folded back flange part 2a along an end edge 2b. Instead of a semicircular notch, a notched part of a circular shape or oblong shape may be provided. Laser welding is executed after a clearance (a) between both sheets is visually confirmed from the notched part 4. When the clearance (a) is smaller than a prescribed value, since the melted substance of sheets due to laser welding is blown off by the gas pressure generated from vapor/gasified substance of oil film/rust preventive material on the surfaces of both sheets to cause defective welding, a laser welding point is corrected to an appropriate position. By this method, the defective laser welding resulting from too small clearance between joined faces of both materials is evaded.

IPC: G01B11/24
Filed: 1989-04-24
Abstract: PURPOSE:To detect the body, etc., over the entire periphery without rotating the body by equipping a lighting unit with a light source and lighting the surface of the body with light, which is narrower than the diameter of the body, in the axial direction of the body at a specific angle of incidence from outside in the peripheral direction of the body. CONSTITUTION:The lighting unit 7ab is equipped with the light source 8 and the surface of the body is lighted with the light, which is narrower than the diameter of the body, in the axial direction of the body at the specific angle theta of incidence from outside in the peripheral direction of the body. Therefore, even if the external surface of the body is uneven, light and shade due to the unevenness can be formed. Further, a lighting device 4 is constituted by arranging plural units 7ab annularly outside in the peripheral direction of the body. Therefore, even if the diameter of the body becomes large, the number of units 7ab is increased or the width is adjusted to enable the lighting, thereby eliminating the need to rotate the device 4. Further, a camera 5 is arranged at the angle theta outside in the peripheral direction of the body and receives an image of the body. Therefore, the camera 5 need not to be rotated. Then an image processor 6 converts the image received by the camera 5 into a binary signal and compares the signal with the normal article pattern of the body to decide whether or not the external surface is uneven.

Abstract: PURPOSE:To accurately perform calibration and detect a tilt angle by providing a couple of 1st and 2nd circular coils axially in front of and behind a uniaxial vector type magnetic sensor, suspended from a two-axial gimbals, at an equal distance and supplying specific currents. CONSTITUTION:When a switch 14 is placed on the side of its terminal (a), the positive voltage of a battery 15a is applied to a diode 13a to supply the currents to the coils 11a and 11b in opposite directions. A magnetic field is established in the detection direction of a magnetic sensor element 4 and this magnetic field is produced radially in the same circumferential direction even if the case of the element 4 rotates, so invariably correct calibration is performed. When the switch 14 is placed on the side of its terminal (b), the negative voltage of the battery 15b allows the currents to flow through the coils 12b and 12a in the same direction. Then the magnetic field produced by the element 4 has constant intensity in the axial direction of the coils, but is zero in the radial direction. The magnetic field which is produced axially allows a signal corresponding to the tilt angle of the case to be applied to the element 4, so this tilt angle can be measured.
