Title: Microwave oven
Inventor: YAMAGUCHI MASAAKI
IPC: F24C7/02
Filed: 1989-05-15
Abstract: PURPOSE:To prevent a decrease in the sensitivity due to water drops by a method wherein the heat receiving surface of a pyroelectric element is tilted at more than a particular angle so that water drops flow down even if steam condenses on the heat receiving surface and turns into water drops. CONSTITUTION:A pyroelectric element 5 consists of a plane ceramic plate 24 having pyroelectric effect, electrodes 25 and 26 and a metal plate 27. When a high temperature gas comes in contact with the metal plate 27, heat is transferred to the ceramic plate 24 through the metal plate, and the ceramic plate 24 generates a voltage due to the pyroelectric effect. An item 6 to be heated in a heating chamber 7 is inductively heated by microwave generated by a magnetron 10. When temperature approaches to a temperature near the boiling point of water contained in the item to be heated, a lot of high temperature steam is generated, led to an air duct 9 after passing through a vent provided on the ceiling of the heating chamber 7, and brought in contact with the pyroelectric element 5. As the metal plate 27 as heat receiving surface of the pyroelectric element 5 is tilted at more than 15 deg. to the horizontal plane and water drops flow down before water drops of dew grow so large that they produce an influence on the sensitivity, a decrease in the sensitivity due to dew formation is prevented.

Title: Switch device
Inventor: WATANABE MAKOTO
IPC: H01H9/16
Filed: 1991-05-27
Abstract: PURPOSE:To fetch a state signal from the identical signal line and simplify the wiring by outputting a pulse signal of a pattern corresponding to a make- and-break of a switch and a detection and preview state of a failure. CONSTITUTION:Based on the output of a photoelectric switch 13, a control part 25 judges whether an output level is in a preset-on region or in a preset-off region or in a preset failure preview region of an effector. Pulse signals corresponding respectively to a normal on-and-off or to an on-or-off in a failure preview state are given to a transistor 26. In this way, as both states of a make-and-break of switch and a failure are displayed altogether, by means of the pattern of a pulse signal a switch signal line and a failure signal wire can be constituted as the same signal.
