Filed: 1995-12-20
Abstract: PROBLEM TO BE SOLVED: To provide a refrigerating cycle which can realize a light and compact cooler to cool a cold storage medium built in a cold roll box. SOLUTION: High pressure air to be supplied from outside undergoes a heat exchange with return air from a cooling chamber 7 by a first air/air heat exchanger 3 to be cooled and is introduced into an expander 4 to be expanded adiabatically by a pressure chamber so that the temperature is lowered to supply low temperature air to a cooling chamber. In an air refrigerating cycle thus arranged, the return air from the cooling chamber 7 is heat exchanged with the air entering the expander 4 and then, introduced to a compressor 5. The heated air with a raised pressure by the compressor undergoes a heat exchange with ambient air by a second air/air heat exchanger 6 to be cooled and is made to converge with the primary air entering the first air/air heat exchanger 3.

Title: Hunting shot
Inventor: YAMAMOTO NOBORU
IPC: F42B7/02
Filed: 1992-12-15
Abstract: PURPOSE:To provide a less-expensive hunting shot which does not make any possibility to bring about pollution of lead poisoning even if the shot is accidentally eaten by birds and the like after the shot is launched at a hunting field and dropped onto the ground. CONSTITUTION:At least a surface of a shot 1 loaded in a ball cartridge of a hunting shot is made of ceramics. For example, an entire shot 1 is made of ceramics or the surface of metallic particle 2 is enclosed by an outer shell 3 of ceramics. There is no possibility that a lead poisoning occurs even after the shot is accidentally eaten by birds and the like. In the case that the shot 1 is of one in which the surface of the metallic particle 2 such as lead is enclosed by an outer shell 3 made of ceramics, the outer shell 3 of ceramics which is chemically stable prevents inner lead from being melted out, resulting in that even if the shot is accidentally eaten by birds and the like, lead does not melt out in the body of birds and the like, and so there is no possibility that a lead poisoning occurs. If the entire shot 1 is made of ceramics, the lead does not melt out even if the shot is cracked under a certain shock and so this shot is the most safe one.
