Title: Cooler
Inventor: YAMAGUCHI SAKUTARO
IPC: F25B19/00
Filed: 1989-07-27
Abstract: PURPOSE:To evaporate water to perform a cooling operation and to supply the cooled water to a heat exchanger so as to cool air by a method wherein a vacuum pump is applied to reduce a pressure within a container having water therein. CONSTITUTION:As an interior part of a container 10 having water 11 contained therein is reduced in its pressure by a vacuum pump 14, an amount of evaporation of water 11 is increased. In particular, as an interior of the container 10 is less than an evaporating pressure of water, a boiling of water 11 is generated, the evaporating amount is remarkably increased and at this time the water 11 is retrieved from its evaporation heat and cooled and at the same time its water vapor is discharged from the vacuum pump 14. The cooled water is taken by a water pump 15 and sent to an indoor heat exchanger 17 through a piping 16. A heat exchanging operation is carried out between the air fed from a fan 18 rotated by a motor 19 and the cooled water, thereby the air is cooled and the cool air is fed into the room. The water heated through the heat exchanging operation passes through a piping 20 and it returned back to a container 10 and the water is further cooled again. The water evaporated is discharged and as the water 11 in the container 10 is decreased, the control device 25 properly opens a valve 13 in response to an amount of water measured by a water surface meter 21 and the water is replenished from an outer piping 12.

Title: Method for inhibiting blocking
Inventor: ONABE TAKAYUKI
IPC: C09J7/02
Filed: 1997-07-04
Abstract: PROBLEM TO BE SOLVED: To inhibit a hot melt adhesive from blocking by sticking a film being not pressure-sensitively adhesive on the side opposite to that of sticking to the exposed surface of a coated hot melt adhesive by a transfer process. SOLUTION: A laminated film for a transfer film comprising for example a supporting film (e.g. polyester), a release layer (e.g. paraffin wax), a protective layer (film to be transferred) (e.g. acrylic resin) and an adhesive layer (e.g. acrylic resin) is stuck to transfer its protective layer to the exposed surface of a hot melt adhesive based on for example an ethylene/vinyl acetate copolymer resin, a polyamide resin, a polyester resin, a thermoplastic elastomer or a polyolefin and optionally containing e.g. a tackifier or being of a type of NCO-terminated polyurethane. Deterioration in quality due to the deposition of dust on the exposed surface or the reduced productivity due to the reduced transferability of the bonded member, both of which are caused by the pressure- sensitive adhesiveness of the exposed surface, can be prevented.
