Title: Manufacture of electrophotographic sensitive body
Inventor: TAKANO MASAHIDE
IPC: G03G5/082
Filed: 1987-09-17
Abstract: PURPOSE:To reduce variance of negatively chargeable characteristics by raising the temperature of a substrate to >=60 deg.C at the time of forming an interlayer to be interposed between a conductive substrate and a photosensitive layer in order to lower the dependency of the interlayer on Te concentration and film thickness. CONSTITUTION:The interlayer 2 made of an Se-Te alloy containing 25-50% Te is vapor deposited on the surface of the conductive Al substrate 1 kept at a temperature of >=60 deg.C, and then, a photosensitive layer composed of an electric charge transfer layer 3 and a charge generating layer 4 and a surface protective layer 5 are successively laminated. Microcrystals are properly produced in the interlayer 2 by elevating the substrate temperature at the time of vapor deposition of the interlayer for the purpose of promoting injection of positive holes to the layers 3, 4 from the side of the substrate 1, and the action of the injection of the positive holes can be made uniform even when differences occur in the Te concentration or the film thickness of the layer 2, thus permitting variance of the negatively chargeable characteristics to be reduced.

Title: Camera
Inventor: TAKAGISHI HIROAKI
IPC: G03B17/18
Filed: 1988-09-20
Abstract: PURPOSE:To make the structure of a main body thin by arranging a LCD, which displays information, on the plane perpendicular to a photographing optical axis.

IPC: C21B7/14
Filed: 1990-09-04
Abstract: PURPOSE:To safely, surely and automatically inject molten iron into a ladle by controlling the tilting of a tilting spout based on the tilting angular velocity calculated from the molten iron receiving rate. CONSTITUTION:When a tilting spout 2 is switched and tilted, a tilting angle is calculated by a computing element 10 from the molten iron receiving rate 12 at the spout 2 of the molten iron transferred from a molten iron runner and the tilting angle from a tilting angle detector 9 so that the amt. of molten iron remaining in the spout 2 when tilted is kept constant.
