Title: Electric water warmer
Inventor: HARA KAZUO
IPC: F24H1/18
Filed: 1990-06-08
Abstract: PURPOSE:To reduce wasteful discharge of hot water even when a hot water feed faucet is left unclosed and to prevent the occurrence of deficiency in hot water through ensurance of a given amount of hot water in a hot water storage tank by a method wherein supply of water is stopped through closing of a water feed pipe when water is raised to a level higher than that of a thermostat. CONSTITUTION:When hot water is continued to be discharged wastefully as a result of a hot water feed faucet 4 being left unclosed, when water is raised to the level of a second thermostat 7, the second thermostat 7 detects it to turn OFF a switch 8 and a solenoid valve 5 is closed to prevent further feed of water to a hot water storage tank 1. When the feed of water to the hot water storage tank 1 is stopped, hot water is not fed through the hot water feed faucet even when the hot water feed faucet 4 is left unclosed, whereby wasteful discharge of hot water is stopped even when the hot water feed faucet 4 is left unclosed. Even when the hot water feed faucet 4 is left unclosed, boiling hot water can remain at a level higher than the mounting position of the second thermostat 7 of the hot water storage tank 1. Even in this case, by turning ON the switch 8, the solenoid valve 5 is opened, and the hot water feed faucet 4 is opened and hot water can be immediately used.

Title: Cassette tape recorder
Inventor: HANAKAWA EIICHI
IPC: G11B15/07
Filed: 1984-07-20
Abstract: PURPOSE:To position accurately a cassette even with a lot of detections by allowing a plate shape projection being a part to be detected of a tape cassette to shut an optical path of a photodetector from a light source. CONSTITUTION:The light is made incident from an end face 23b of a prism 23, reflected in a full reflecting face 23a and reaches a photodetector 24 through the prism 23. The cassette is arranged so that the plate shape projection 13 shuts the optical path on the way of the optical path, that is, between both the prisms 22 and 23. Since the presence of the plate shape projection 13 shuts the light and no lights reaches the photodetector 24, no output of the photodetector 24 is generated. If no plate shape projection 13 exists, the light reaches the detector 24 and an output is generated. Through the constitution above, since no unnecessary force acts on the cassette main body for detection, the cassette is positioned accuracy regardless of a lot of detections.
