Patent JP-S63288847-A (JP)
Title: Conveying roller
Inventor: TAKEDA KAZUO
IPC: B65H27/00
Filed: 1987-05-21
Abstract: PURPOSE:To prevent the shortening of the life of the title roller due to the deposition of paper dust on a bearing by forming the diameter of the opposite part to the lower part of the cylindrical body of a supporting shaft larger than the diameter of the other part of the supporting shaft, within a gap between the inner wall of a cylinder and the outer wall of the supporting shaft. CONSTITUTION:In a roller 20, the diameter of the lower part of a shaft 21 installed on a base plate 7 is largely formed to make a gap created toward the inner face of a roller body 22 minimum within the range of not coming in contact with the inner face. And, sheets of paper which are held between the roller 20 and a belt 5 and conveyed produce paper dust (a) due to a frictional force with the belt 5, and the dust (a) enters from the gap between the shaft 21 and the roller body 22 and is deposited on a bearing 3b. However, since the gap is set to be minimum within the range of noncontact, the entrance of the produced paper dust (a) from the gap into the bearing 3b is greatly reduced. Accordingly, the shortening of life due to the deposition of paper dust (a) on the bearing 3b can be prevented.

Title: Brake liquid pressure generator
Inventor: SHIMIZU KAZUAKI
IPC: B60T13/52
Filed: 1979-09-25
Abstract: PURPOSE: To improve durability of a liquid-sealing seal, by a method wherein a piston portion of a brake master cylinder, protruding into a vacuum chamber in a vacuum type booster, is embraced with a dust boot made of a material being endurable to fuel.  
     CONSTITUTION: In a liquid pressure generator in which a vacuum type booster 1 and a brake master cylinder 2 are coupled together, operations necessary to couple together the device 1 and cylinder 2 are performed such that an opening end of a cylinder body 14 mates a cylinder opening 30 of a housing 4, and a flange 14 of the housing is joined to the housing 4 by means of bolts. A piston part 15, which protrudes toward the inside of a vacuum chamber 6 of the booster 1 is embraced with a bellows dust cover 33 made of a flexible material being endurable to an engine drive fuel. This allows a cover 3 to reliably prevent liquid-sealing seal from being exposed to fuel even if the fuel flows into the vacuum.

Title: Manufacture of cathode plate for alkaline storage battery
Inventor: HENMI TOSHIO
IPC: H01M4/26
Filed: 1986-05-28
Abstract: PURPOSE:To enlarge cathode capacity, by corroding a sintered nickel surface layer in an aqueous solution of raw-material salt so that it becomes an active material. CONSTITUTION:A sintered nickel surface layer is corroded in an aqueous solution of raw-material salt to become an active layer. And corrosion is promoted by heat decomposition of the raw-material salt so that the sintered nickel surface layer becomes an active material. Because the aqueous solution of raw- material salt is strong in acidity, its contact with sintered nickel particles on the sintered substrate causes a corroding reaction to raise PH in the vicinity of the reacting interface and then to generate NiOH(NO3) on the reaction surface, so that it becomes Ni(OH)2 by alkaline substitution. The corrosion layer formed of the sintered nickel particles is hence made to become the active material so that the capacity can be enlarged. Besides, corrosion reaction can be promoted by heating the raw-material salt in the small hole of the substrate after the preceded corrosion reaction.

IPC: G06T1/00
Filed: 1996-05-17
Abstract: PROBLEM TO BE SOLVED: To eliminate the destruction and overlapping of the characters of an original and to improve the recognition rate of an OCR by matching the line pitch of the original and the read line pitch of a scanner. SOLUTION: The original to be read is inserted from a paper feed stacker 50 to the scanner (S501), a read center is matched with a line center (S502) and whether or not to input setting for line feed is inquired from a processor (S504). In response to it, in the case of inputting the setting (Y), the height (N) of the character and the length (M) of a clearance (line pitch) are inputted (S504 and S505). The line for which the read center is matched with the line center is read (S506) and whether or not the line pitch calculated from an inputted setting value is larger than a read width is checked (S507). In the case of a line feeding amount at the time of the line pitch more than the read width (Y), the maximum read width and (the character height + clearance length = the line pitch)-the maximum read width are alternately line-fed.  For line feed at the time of the line pitch <= the read width, the line feed is performed by the set line pitch. When a line feeding instruction is not present, the line is fed by the maximum read width (S514).
