Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To render a screen to be flame-retardant by laminating such a polarizing film that has a reflection plane on its lower surface and the upper surface is subjected to light diffusion treatment on the upper surface on a supporting member with an adhesive. SOLUTION: A polarizing film 2 (such as a PET dye) having a reflection plane 2a on its lower surface and the upper surface of which is subjected to light diffusion treatment is laminated with an adhesive (such as a transparent urethane adhesive) on the upper surface of a base body 1 (such as a PET film). It is preferable to use a member having excellent flame-retardant property for each structural member. For example, a polyvinylchloride film or polycarbonate film can be used instead of the PET film for the base member 1 to obtain more excellent frame retardant property. The reflection plane 2a is formed by sand blasting the lower surface of the polarizing film 2 to form a matted surface and then depositing aluminum (or silver) by vapor deposition thereon. An adhesive is not preferably used between the matted surface and aluminum so as to prevent absorption of light.

IPC: F25C1/18
Filed: 1988-01-26
Abstract: PURPOSE:To prevent an ice making time for clear ice as well as normal ice from being prolonged by disposing a separating plate having multiple holes in it under a cooling plate, and forming a first air passage between the cooling plate and separating plate and a second air passage between the separating plate and a second ice making tray. CONSTITUTION:Cold air cooled in a cooling unit 5 flows into a first air passage from an air inlet 28 by the forced draft of a fan 6 to cool a cooling plate 13, and a first ice making tray 15 is cooled indirectly from under. At the same time, the first ice making tray 15 is heated from above by a heater 11 via a heating plate 12. Thus, the freezing gradually advances from the bottom to make clear ice. Since the leading end of the first air passage is closed by the L-shaped bend of the separating plate 23, cold air passes through multiple small holes 27 in the separating plate 23 to enter a second air passage 26, i.e. the space above a second ice making tray 16. As the cold air passes through the second air passage 26, the water surface in the second ice making tray 16 is cooled to make normal ice.

IPC: H05B6/68
Filed: 1983-01-31
Abstract: PURPOSE:To make a variable resistance for correction unnecessary, and to enable the correction of an original resistance value to be easily effected, by changing, if the resistance value of a sensor for a prescribed gas concentration has changed with time, the changed resistance value to the reference value, that is, to a detection level. CONSTITUTION:Detection level change-over means 18 is connected to a fourth input section IN4 of a central processing unit 10. The detected level change-over means 18 consists of a decoder 19 and a plurality of change-over switches SW1, SW2...SWn for changing over codes of the decoder 19. The selective closing of the change-over switches SW changes over arbitrary the detected level for the central processing unit 10. That is, since the sensitivity of the sensor (S) has changed, when the resistance value of the sensor at the gas concentration C' becomes R', in response to the sensitivity of the sensor (S) a detected level K' changes the detected level from (K) to K', and this change-over is performed by selecting the switches SW of the detected level change-over means 18.

IPC: G21D3/06
Filed: 1989-01-24
Abstract: PURPOSE: To enhance the performance of a nuclear reaction boiler by forming a protection system of three or more independent protection systems. CONSTITUTION: The system includes protective systems, a secondary processing circuit, and a nuclear reaction limiting means. Each protective system at least two neutron flux detector spaced apart at an angular interval of 90 deg. or more, two temporary processing circuit coupled with respective detectors, and an intermediate processing circuit. A falling signal being fed from the output of protective system and received by the secondary processing circuit is formed of an intermediate falling signal. In case of falling of one reaction suppressing elements, one system is faulty when the decrease of neutron flux being received by a plurality of relatively remote detectors from a cavity for receiving the falling reaction suppressing element does not exceed a predetermined threshold variation rate.  Consequently, a secondary falling signal can be provided even when a detector relatively close to the cavity can not feed one falling signal temporarily.
