Specifically, the salt treatment is made while moving sliced fish continuously and/or in such a state that the sliced fish is arranged flat on a tray; the salt treatment is conducted in such a way that the sliced fish is sprinkled with a specified amount of salt and brought into contact with a liquid- absorbing sheet containing a specified amount of salt. The sheet is a water- absorbing fibrous sheet in the form of paper and/or nonwoven fabric and may have a liquid-absorbing layer including a liquid-absorbing material for drips of the sliced fish. The final sliced fish is vacuum-packaged with an air- impermeable film. The fish is pref. raw salmon.

Title: Releasing agent for metal spraying
Inventor: YUGAWA NOBUHIKO
IPC: B29C39/10
Filed: 1983-12-05
Abstract: PURPOSE:To simplify the releasing of a mold with a better attachment of sprayed metal by having a specified amount of an amphoteric ionic polymer contained with the rest mainly composed of a solvent for dissolving or dispersing the polymer. CONSTITUTION:More than 0.001wt% of an amphoteric ionic polymer A is contained with the rest mainly composed of a solvent B for dissolving or dispersing the polymer A. After the formation of a film of a releasing agent for metal spraying on a die surface, a metal spraying is performed on the film to ensure a better attaching property of metal sprayed while simplifying the work of withdrawing a metal-resin composite from a mold. When the amount of the amphoteric ionic polymer A is under 0.001wt%, this is not desirable because the attaching property of metal sprayed is so poor to readily cause such troubles as forming little metal film or peeling off of the metal film during the spraying work. There is no upper limit to the amount of using the polymer and it is used in any range unless enhanced viscosity makes the work difficult to do with an increase in the amount of use.

Title: Method and device for heat insulating picking device
Inventor: OSAWA AKIO
IPC: B65G1/137
Filed: 1996-08-29
Abstract: PROBLEM TO BE SOLVED: To cut off heat escaping outside through a casing, and prevent firing by overheat of a heating element and overheat of a part by covering a casing inner wall with heat insulating materials, and covering a part to contact with and come close to the heating element with a fire resistant heating insulating material. SOLUTION: In a casing 17, an inner wall is covered with heat insulating materials 23 and 25 composed of polycarbonate resin and a fire resistant heat insulating material 27 composed of rock wool felt. Since a flat heating element 31 fixed on the fire resistant heat insulating material 27 comes close to a connector 21, the connector 21 is covered with a fire resistant heat insulating material 29 so that heat radiated from the flat heating element 31 is not directly applied to the connector 21. The fire resistant heat insulating material composed of rock wool felt is rich in fire resistance, and even if it is brought into close contact with the flat heating element 31, damage by heat such as melting and damage by a fire is not caused. Since it contains air, there is an advantage that heat insulating performance is high.
