Patent JP-H10159803-A (JP)
Title: Accumulator
Inventor: NOGAMI HIROSHI
IPC: F15B1/08
Filed: 1996-11-28
Abstract: PROBLEM TO BE SOLVED: To enable any large-sized metallic container to be unnecessary by making an accumulator directly connectable to a pump delivery pipe by providing a pressure variation absorbing member whose volume changed reversible to any change in the internal pressure along the longitudinal direction inside of a tube body in which fluid passes through. SOLUTION: Fluid discharged from the delivery port of a pump flows from the central hole 41A of the first end plate 41 into a flow passage 2 and is discharged from the central hole 42A of the second terminal plate 42. When a pressure in the flow passage 2 rises, the walls on the flow passage sides of air chambers 11a to 11d are pressed to the pipe wall side of a tube body 3 and volume variable parts 1a to 1d are contracted and also the sectional area of the flow passage 2 is enlarged. Thereby, any pressure rise in the flow passage 2 is absorbed.  On the other hand, when the pressure in the flow passage 2 descends, because the walls on the flow passage 2 sides of air chambers 11a to 11d are pressed to the central side of the tube body 3 by air pressure sealed in the air chambers 11a to 11d, the volume variable parts 1a to 1d are expanded, resultantly the sectional area of the flow passage 2 is contracted. Accordingly, any pressure drop in the flow passage 2 is absorbed.

Title: Printable information bulletin sheet
Inventor: IGAWA TATSUYA
IPC: H01F1/11
Filed: 1994-11-29
Abstract: PURPOSE: To make it possible to smoothly feed a printable information bulletin sheet to a general printer and to print the sheet with good printability by specifying the thickness, modulus of bending elasticity and surface magnetic flux density of the sheet to a specific value range. CONSTITUTION: This printable information bulletin sheet is a sheet formed by laminating a layer 4 to be printed on a flexible magnet layer 2. The thickness of this sheet is 0.1 to 0.4mm, the modulus of bending elasticity is 10 to 500kg/mm<2> and the surface magnetic flux density is >=50 gauss. While the sheet is wound around a platen in the printer, the sheet moves and is subjected to good printing by a printing head. At this time, the sheet to be printed for the printer has an adequate thickness, bending elasticity and magnetic force and, therefore, such things that the sheet fails to be wound around the platen prior to printing and conversely that the sheet is held wound around the platen and is hardly dischargeable after printing do not arise. The smooth sheet feeding is thus assured.

Title: Drum type running shearing machine
Inventor: KATO HEIJI
IPC: B23D25/12
Filed: 1991-11-07
Abstract: PURPOSE:To simply accelerate drums before shearing and to enable a plate into a shearing machine at a high speed. CONSTITUTION:A pair of upper and lower drums 11 may be elevated by links 19, 20, and the upper drum 11 is directly coupled to an eccentric shaft 24 which is rotated at a speed ratio of one to an integer number, with respect to a spindle for driving the drums so as to elevate the upper drum 11.
