Title: Manufacture of heat-sensitive lithographic printing plate
Inventor: HOTTA HISASHI
IPC: C25D11/18
Filed: 1999-12-22
Abstract: PROBLEM TO BE SOLVED: To suppress the formation of aluminum and to further suppress the adherence of aluminum hydroxide to an aluminum support by providing a photosensitive layer on the support obtained by treating an anodized aluminum base plate with a water solution having a specific pH. SOLUTION: An aluminum plate is a plate-like material of an aluminum alloy or the like containing pure aluminum or aluminum as a main component and an infinitesimal amount of heteroatom. As the heteroatom, that of silicon, iron, manganese, copper, magnesium, chromium or the like is used. In an anodized aluminum support, formation of aluminum hydroxide is suppressed, adherence to the support is suppressed, and to eliminate a fault of an appearance, it is treated with acid water solution having a pH of 1.5 to 5 or preferably 2 to 4. If the pH is lower than the 1.5, an anodized film is dissolved, and hence a deterioration of stain in association with an increase in a pore size of the anodized film feasibly occurs. If the pH is higher than the 5, the formation of the oxide film cannot be prevented, and a fault of an appearance cannot be suppressed.

Abstract: PROBLEM TO BE SOLVED: To prevent micro droplets remaining on the inner surface of the hat- sealed part of a pouch mouth. SOLUTION: A release sheet 18 supported on a holding plate 16 is spread in a suspended state over the front surface of the vessel press-holding surface 14 of a seal bar 10 having a heat element 11, and a specified heat insulation gap 20 is ensured between the press-holding surface 18 and the release sheet 18. A temperature of the release sheet 18 lowers ordinarily through the existence of the heat insulation gap 20, and the seal bar 10 is pushed in the direction of arrow 21 so as to press-hold a pouch 22 in between the seal for and an opposite material 13, and immediately thereafter, the pouch 22 has no abrupt temperature transfer. Accordingly, water vapour pressure adhered to the inner surface of the press holding part is not raised explosively, so that an escape time of moisture evaporation is saved through the small gap.

Title: Absorption type refrigerating machine
Inventor: HIROHATA OSAMU
IPC: F25B15/04
Filed: 1990-12-27
Abstract: PURPOSE:To enhance the cooling performance of an absorption type refrigerating cycle using ammonia. CONSTITUTION:An ammonia solution supply pipe 20 of bellows-like type is inserted in an L-shaped generating pipe 11a. During bending process of the ammonia solution supply pipe 20, the bellows-like part expands and contracts, preventing the ammonia solution supply pipe 20 from being compressed flat, so that the pipe friction loss of the ammonia solution supply pipe 20 is a little. Therefore, heat exchange between low-temperature ammonia solution in the ammonia solution supply pipe 20 and high-temperature lean ammonia solution in the generating pipe 11a is stimulated. The temperature of the lean ammonia solution falls and absorbs more ammonia gas in an absorber 15. The pressure of mixture gas entering an evaporator 14 drops, so that the pressure in the evaporator 14 falls and the evaporating temperature of ammonia is reduced.
