摘要： PROBLEM TO BE SOLVED: To prevent insufficient heating of a specified part of a rice cooker corresponding to an open part of a bottom heater by setting the concentration of heater wires of a part of a cover heater corresponding to the open part of the bottom heater. SOLUTION: In a heat reserving rice cooker provided with a bottom heater for reserving heat and a cover heater for preventing bedewing, a non-heating part 15 made by an open part of the bottom heater H is so formed as to be disposed on the left side in a rear part of a main body case 1 and an opening 31a of a cover heater unit 31 is so formed as to be disposed on the right side in the rear part of the main body case 1, Due to this structure, a specified part of the cover heater unit 31 which is opposite to the non-heating part 15 is located on the left of the opening 31a. By arranging heater wires 33 in high concentraion in this part of the cover heater unit 31, a calorific power by the heater wires 33 arranged in a part of the cover heater 31 which is right above the non-heating part 15 is increased and a specified part of a ring-shaped packing corresponding to this part is heated intensively.

摘要： PROBLEM TO BE SOLVED: To keep a display panel of a display panel from being clouded by a combustion exhaust leaked into an auxiliary chamber from a heating chamber within a body case while ascending through an exhaust path by arranging a sealing member between the periphery of a display screen at a display part and the rear of an operating panel corresponding to the periphery. SOLUTION: The peripheral part of a display window 14 forms a rectangular annular frame part 10a by being bent on the rear thereof and the tip face of the frame part 10a is made to face a peripheral part of a display screen of a liquid crystal display panel 16. A packing 5 is a rectangular annular body the same in size and shape as the periphery of the display screen of the liquid crystal display panel 16 and the thickness thereof is set slightly larger than the distance to the tip of the frame part 10a from the display screen of the liquid crystal display plate 16 while a double side adhesive tape 50 is applied on the enter area facing the display screen of the liquid crystal display panel 16. One adhesive surface of the double side adhesive tape 50 is applied on the periphery of the display screen of the liquid crystal display panel 16 and the packing 5 is mounted in such a fashion as to make a sealing between the display screen of the liquid crystal display panel 16 and the frame part 10a.

摘要： PURPOSE: To simplify the constitution of an operation switch device and shorten the time required for assembling by making an operation button of an elastic synthetic resin material, elongatingly forming a support piece on a part of a circumferential edge, and also providing a movable piece in the opposite side of the support piece. CONSTITUTION: A tip part of a support piece 21 of an operation button 2 made of elastic synthetic resin is fixed to an operation panel 1 in a cantilever state. A cover sheet 3 is stuck to the panel 1 in such a state as covering the button 2 so that the button 2 is positioned to the panel 1. A movable piece 22 is provided in the opposite side of the piece 21. The button 2 is thus returned to its initial position before the pressing by an elastic return force of the piece 21 of the button 2 so that the necessity of an elastic plate is eliminated and the button 2 is held to the panel 1 by the sheet 3 to that the constitution of the panel is simplified. Therefore, the whole device can be simplified and the time required fo assembling the device can be shortened. The anti-fatigue strength of the piece 21 fixed of the panel 1 becomes satisfactory so that a long-time stable operation of the button 2 can be secured.

摘要： PROBLEM TO BE SOLVED: To realize a thermosensitive device capable of guiding the vertical movement of a plate type member without using a guide rod. SOLUTION: The thermosensitive device comprises a substantially tubular case 4, a cover member 20 with which the upper opening of the case 4 is covered, the plate type member 7 vertically movably housed in the case 4, a lever 8 extending downward from the plate type member 7, ordinary temperature ferromagnetic and high temperature nonmagnetic ferrites 3a and 3b fixed to one of the cover member 20 and the plate type member 7 and a permanent magnet 5 fixed to the other of the cover member 20 and the plate type member 7. On the bottom of the case 4, a lever passing hole 4b is formed for permitting the vertical movement of the lever 8 and inhibiting the rotation of the lever 8 about an axis.
