Abstract: PURPOSE:To improve the strength and the corrosion resistance and measure accurately a very minute quantity of radioactivity in sample water by forming a part, with which sample water is brought into contact, with a synthetic resin reinforced by fibers having no radioactivity. CONSTITUTION:A lining layer 4 consisting of an unsaturated polyester resin reinforced by carbon fibers is formed on inside faces of a vessel 1 and a cover 2. A flow-in tube 5 and a flow-out tube 6 of sample water are formed with an unsaturated polyester resin hardened material reinforced by carbon fibers and are attached to the lining layer 4 of the vessel 1. Conduits 7 and 8 are formed with an unsaturated polyester reinforced by glass fibers and are so constituted that sample water is flowed into the vessel 1 through the conduit 7 and the flow-in tube 5 and is flowed out through the flow-out tube 6 and the conduit 8. Radiation shielding materials 9 and 10 have shells constituted with steel plates, and lead is packed in them. Consequently, since the part with which sample water is brought into contact is constituted with the synthetic resin reinforced by fibers having no radioactivity, the counting rate of the background is reduced considerably.

Title: Control device of heat pump system
Inventor: YASUI YOSHIAKI
IPC: F24F11/02
Filed: 1985-10-04
Abstract: PURPOSE:To prevent discrepancy between the operation mode and the set-up mode by judging an actual operation mode that corresponds to the position of a change-over valve from a temperature detection signal of the circulation water temperature. CONSTITUTION:A heat pump system control device is constituted with temperature detection means c which detects the temperature of at least one of the flow-in circulation water and the flow-out circulation water to a heat pump the operation of which is started by operation control means a in room cooling or in room heating, mode judgeing means d which judges the mode of the actual operation in the heat pump b from the temperature detection signal of the temperature detection means c, and abnormality judgment means f which compares the mode of the actual operation judged by the mode judgment means and the set-up mode set by operation means and, if both modes coincide, issues to the operation control means an instruction to continue the operation and, if both modes do not coincide, outputs a signal to take an action for abnormality. Since the operation mode is thus judged from the temperature of the circulation water, operating in a mode different from the one desired due to misoperation is prevented.

Abstract: PURPOSE:To improve the quality of a received picture under a signal input condition containing a ghost in a movable body by controlling a directivity switching device by comparing ratio between video signals before and after the directivity switching of the directivity switching device and a ghost signal. CONSTITUTION:After power is turned on and channel selection is completed, the output voltage of a ghost signal amplitude decision circuit 7 is held while an antenna directivity switch 2 is kept at initial setting, and after the directivity of the switch 2 is switched, the output voltage of a video signal amplitude decision circuit 6 and the output of the circuit 7 are inputted to an antenna directivity switching control circuit 8. The circuit 8 compares these two voltages, and switches the directivity according to a prescribed comparing condition. Thus, the directivity is switched into a direction where the ghost becomes less or an antenna signal input level becomes higher according to ghost signal amplitude ratio. Accordingly, the quality of the received picture in the movable body is improved.
