Title: Glow discharge cracking device
Inventor: HIGUCHI HISASHI
IPC: C23C16/24
Filed: 1986-01-31
Abstract: PURPOSE:To decrease powder contamination and to improve the yield of production by disposing two conductors to face each other to the side outer than a glow discharge region to form a lower discharge region. CONSTITUTION:The 1st conductor 24 which is electrically conducted to a substrate 15 and the 2nd conductor 25 which is electrically conducted to an electrode plate 14 are formed on the outside of the discharge region for forming the film of a-Si. The 1st conductor 24 corresponds to a base 13 and forms the lower discharge region 26 continuous with a main discharge region region 27 between the same and the 2nd conductor 25 facing said conductor. Part of the gaseous product by the glow discharge is discharged through the lower discharge region 25 and the balance sticks onto the electrode plate 14, the 1st and 2nd conductors 24, 25, thus growing to a film shape, in the stage of forming the a.Si layer. An etching gas is introduced into the vessel to generate the glow discharge and to remove the thin films formed on the surfaces of the electrode plate 14 and the conductors 24, 25 after the manufacture of an a-Si photosensitive drum, etc. The next amorphous semiconductor layer is formed without defects in the film formation by the above-mentioned mechanism.

IPC: G07B15/00
Filed: 1998-02-02
Abstract: PROBLEM TO BE SOLVED: To prevent illegal entering and leaving by specifying the owner of a card when entering/leaving by the card can not be permitted and informing the owner of that. SOLUTION: When a user enters a ticket examining passage P, a card C possessed by the user is held over a communication area 3 provided on the entrance side of the passage P. When the card C is held over the area 3, data are transmitted and received between a main body G and the card C to execute arithmetic processing of entering/leaving by the controller 6 of the main body G. When entering/leaving can not be permitted as a result of the arithmetic processing of entering/leaving, the name of the possessor of the card C is extracted and the extracted name and characters guiding that passing through is not permitted are displayed. Thereby, even in the case of a doorless type, the possessor of the card C is specified and the effect is guided when entering/ leaving is rejected. Thus, illegal entering/leaving is prevented.

Filed: 1994-02-18
Abstract: PURPOSE:To surely and easily obtain the stable reproducibility of extra highlight even when toner concentration in a developing device is changed in order to control the concentration at a middle/high concentration part to be constant. CONSTITUTION:When a power source is judged to come into on-state from off-state at a step Sl after it is turned on, humidity in an image forming part is measured by a humidity sensor at a step S2. Then, it is decided by an arithmetic unit whether the measured humidity is <=40%, between 40% and 70% or >=70% at a step S3. At a step S4, a chopping wave bias is set to be negative when the humidity is <=40%, set to be zero when it is between 40%, and 10% and set to be positive when it is >=70%. Then, the turning-on time of a laser is controlled based on the set chopping wave bias and the density of an image is adjusted. Thus, the density of the image at the extra highlight part is adjusted.
