Filed: 1988-12-09
Abstract: PURPOSE:To connect an optical element to a face plate without a wiring and to eliminate the need of a special wiring process by forming metallic wires having conductivity of at least >=2 systems by mixing them with a fiber along the optical axis direction of an optical waveguide body. CONSTITUTION:The necessary number of conductor metals 3, for instance, wires of Au, Cu, Ni, Ag, covar, etc. are allowed to exist along the optical axis direction of a face plate between a fiber and a fiber for constituting face plate 12, 13.

Abstract: PURPOSE: To prevent supercooling state and frosting of a cooling plate, by conducting cold air into an ice house through an air vent on the outer periphery of the cooling plate and allowing a part of the conducted cold air to flow along the cooling plate. CONSTITUTION: When an ice tray 15 is housed in an ice house 22 and an ice- making switch is pressed, the upper surface of the ice tray 15 is heated by a heating plate 12 of a heater 11 while the lower surface thereof starts to be cooled by a cooling plate 13. Major part of cold air passing through a ventilation flue 14 flows along the bottom surface of the cooling plate 13 to cool the same, while a part of it flows through a vent 23, along the bottom of a first ice tray 15 and the upper surface (water surface) of the first ice tray 15, and through a front opening to return to a return air duct 19. In due course of time, the temperature of water in the ice tray 15 reaches 0 deg.C when the water infallibly starts to freeze due to wind slightly flowing along its surface without being supercooled.  On the other hand, water vapor evaporated during the formation of transparent ice cannot stick to the heating plate 12 because it has a high temperature, while cold air from the air vent 23 is slightly flowing along the cooling plate 13 to prevent it from being frosted.
