Title: Method of sealing vacuum vessel
Inventor: MATSUNAGA HIROYUKI
IPC: H01J9/26
Filed: 1984-09-28
Abstract: PURPOSE:To prevent oxide films from being applied on a rod and an end plate as well as simplify a process of cutting by effecting processes of evacuation and brazing at the same time. CONSTITUTION:A rectangular groove 11 is provided in the middle of a rod A1, around whose groove 11 a brazing material 16 is wrapped in a state of the brazing material being fitted into said groove.

A weight 10 is placed on the upper surface of the end plate A3. Throwing the captioned vessel into a vacuum exhaust device and heating it to temperature from 800-1,100 deg.C while evacuating it, a vacuum is formed in the vessel, while the end plate A3 is released from the stoppage thereof owing to melting of the brazing material A16. Accordingly, the vessel is lowered due to downward force of the weight 10 to be brought into contact with a brazing material B17, brazed onto the upper end of the insulating cylinder 5, and hence sealed by the end plate A3.

Title: Electrophotographic photoreceptor substrate and electrophotographic photoreceptor
Inventor: YAHAGI HIDETAKA
IPC: G03G5/00
Filed: 1998-07-16
Abstract: PROBLEM TO BE SOLVED: To provide a photoreceptor substrate having a good coating film without causing any crack by applying a current for a specified time in the anodic oxidation process to form an aluminum anodically oxidized film. SOLUTION: An aluminum substrate 11 having an aluminum anodically oxidized film of 5 to 12 μm thickness, preferably 8 to 10 μm on its surface is used. If the thickness of the film 12 is less than 5 μm, the photoreceptor has poor blocking property during electrification. If the film thickness exceeds 12 μm, cracks are easily produced. The energizing time in the anodic oxidation treatment to form the film 12 having the specified film thickness range above described is controlled to >=30 min and <=40 min, preferably >=30 min and <=35 min. By controlling the film thickness to 5 to 12 μm in the energizing time above described, the current density for the electrolysis can be decreased and the electrolytic voltage can be decreased, which results in high cell density, namely, high energizing hole density as the film property of the oxidized film.  Thereby, even when the sealing rate is increased, production of cracks in the oxidized film by heat treatment is prevented.

IPC: G05B13/02
Filed: 1988-08-12
Abstract: PURPOSE:To apply a controller to all environmental condition inducing the characteristic variation of a process by successively updating a gain schedule curve based upon many twin data each of which consists of a matching factor and an adaptive index. CONSTITUTION:A matching ability deciding means 4 inputs an operation variable to be the output of a controller 2 and the output of a process 3 and operates a matching factor e.g. every fixed period. On the other hand, gain corresponding to an adaptive index is found out by a scheduling factor 7 based on a gain schedule curve. The control parameter of the controller 2 is determined based on a multiplied value between the gain and the matching factor and the process 3 is controlled by the controller 2. When the number of twin data stored in a data base reaches an optional value, all the stored twin data are analyzed and a gain schedule curve updating means 6 updates the gain schedule curve in accordance with the analyzed results. Consequently, an always optimum control parameter can be adjusted.
