Patent JP-H02150621-A (JP)
Title: Electric range unit
Inventor: IZUMITANI TAMOTSU
IPC: F24C7/02
Filed: 1988-11-30
Abstract: PURPOSE:To prevent the damage of electronic components caused by thermal convection by installing a ventilation space between the upper part of a heatering case and the lower part of an electric range and a ventilation device in the rear part, a thermostat which operates the ventilation device on the top board of the heatering case on the opposition side of the ventilation space and positioning the thermostat in the front of the ventilation device. CONSTITUTION:An open air is adapted to flow into an oven base 28 from an suction air port 28a by the application of an electric oven 27, thereby producing heat convection which flows out from an exhaust air port 28b and tending to rise along the front of a main body 29 of an electric range unit. A thermostat 36 detects the temperature of a top panel of the oven base 28, turns on an inside contact, operates a drive motor 33a of a ventilation device 33, generates air convection. Since the air convection flows out into the open air from an ventilation exhaust port 34 passing through a ventilation space 32, the heat convection generated by an electric oven 27 forcedly flow out forward. As a result, an operation section 31 positioned above is not subjected to a rise in the temperature induced by the heat convection. Even when the operation section 31 is formed with an electric circuit, this construction makes it possible to prevent the electronic components from being damaged by the heat convection.

Title: Thermal transfer sheet
Inventor: YAMAUCHI MINEO
IPC: B41M5/392
Filed: 1989-11-27
Abstract: PURPOSE:To obtain a thermal transfer sheet which disables printing suited for alteration and forgery by providing a thermally melting ink layer containing sublimable dye on one surface of a base sheet. CONSTITUTION:Thermally melting ink consists of pigment, sublimable dye and vehicle, and also may be added with a variety of additives if necessary. A thermally melting ink layer 2 is formed on a base sheet 1 directly or indirectly. The ink layer 2 surface of this thermal transfer sheet is piled on the card base 5 in such a manner that the former faces the dye receptive surface 7 of the latter. Then these two parts are heated on the rear using a thermal head 3 and consequently, an ink layer 2 is transferred to the dye receptive layer 7. In this case, at least, part of the dye in the ink layer colors the interior of the dye receptive surface 7 due to heat during printing to form dye characters 9. If the ink characters 8 formed like this are physically peeled off, the ink layer 8 is removed but the dye characters 9 cannot be removed. Therefore, if other characters are formed on these dye characters 9, both never becomes piled on each other. Thus, any alteration or forgery cannot be concealed.

Title: Resin mold type high-voltage silicon diode
Inventor: YAMAGUCHI KESAMITSU
IPC: H01L23/29
Filed: 1986-12-22
Abstract: PURPOSE:To reduce air gap generating on the boundary between a lead wire and resin, and decrease the deterioration in backward characteristic with time, by setting the thermal expansion coefficient of an epoxy resin used for a mold in a specified range. CONSTITUTION:By fixing a plurality of Si diode pellets 1 with a wax material, a laminate is constituted, on both ends of which lead wires 3 made of oxygen free copper with a plated layer 4 are fixed. After the laminated is coated with a surface protecting layer 5, transfer molding is performed by applying an epoxy resin 6 having a thermal expansion coefficient in the range of 1.40X10<-5>-1.80X10<-5>/ deg.C. Thereby, air gap generating on the boundary between the lead wire of the diode and the resin can be reduced, while the initial backward characteristics of the diodes is kept satisfactory. As the result, the permeation of external moisture can be restained, and the deterioration of backward characteristics of diode with time can be remarkably decreased.

Title: Sheet feeding device
Inventor: MURAMATSU HIDEO
IPC: B65H3/46
Filed: 1987-12-02
Abstract: PURPOSE:To perform the feed of a sheet with high probability when a slip occurs to a feed roller by providing a control means which reverses the feed roller when a sensor does not detect arrival of a sheet and thereafter rotates it forward again. CONSTITUTION:When copying is started, a feed motor M1 is run forward, and sheets on a feed tray 42 are delivered through rotation of a feed roller 22. After a specified time starting from arrival of the sheet at a feed sensor 350 elapses, the feed motor M1 is stopped. When, the feed motor M1 is run for a time approximate two times as long as that in which the sheet is conveyed to the feed sensor 350, the sheet is not conveyed to the feed sensor 350 and the feed sensor 350 is not turned ON, the feed motor M1 is reversed for a short time once, and thereafter it is run forward to perform a feed motion. By this constitution, when a slip of the feed roller 22 on the sheet occurs, reversing of the fed roller 22 causes change of the state of the sheet, and the sheet is easy to deliver in a normal manner.

Title: Gear type variable speed device
Inventor: INOUE WAHEI
IPC: F03C2/08
Filed: 1998-10-28
Abstract: PROBLEM TO BE SOLVED: To reduce manhours and to constantly maintain sealing performance by making working fluid work in an engaging space between an external tooth gear and an internal tooth gear and providing a working fluid suction part on an axial direction one side end part of both of the gears and a discharge part on the other side end part. SOLUTION: An external tooth gear 4 of an axially supporting part 17 made of a cam decentered only by (e) from a shaft center by rotation of a driving rotation axis 2 is engaged with an internal tooth gear 3 by autorotating and revolving. Working fluid in an oil tank sucked from a suction pipe 18 enters an engaging space 40 of the gears 3, 4 from a comma-shaped suction hole of a rotating disc 5. Thereafter, working fluid flows in the axial direction and returns to an oil tank through a pressure chamber 20 and a discharge pipe 19 from a comma-shaped discharge hole of a rotating disc 6. When opening of a discharge pressure control valve is reduced, discharge pressure rises, torque of the gear 4 is transmitted to the gear 3, and a rotation axis 1 on the output side is converted in speed.  The disc 5 and the gear 4 and the gear 3 and the disc 6 are free to slightly move in the axial direction, slide on each other without making an excessive clearance by working fluid pressure and it is possible to maintain sealing performance. Additionally, assembly and adjustment are facilitated.
