Title: Solenoid changeover valve
Inventor: YAMAMOTO MASAHIRO
IPC: H01F7/06
Filed: 1988-10-05
Abstract: PURPOSE:To prevent a defect of insulation by dew condensation when this winding is used for a very-low-temperature fluid by a method wherein an MI cable is used for the winding for driving use of a plunger. CONSTITUTION:An MI cable 10 is constituted as follows: an outer periphery of a cable conductor 11 is covered with an insulating material 12 such as magnesium oxide or the like; its outer periphery is covered with a metal sheath 13 furthermore; the cable conductor 11 is insulated electrically from the metal sheath 13. In this MI cable 10, the cable conductor 11 is covered doubly by using the insulating material 12 and the metal sheath 13; accordingly, when this cable is wound, an interlayer insulation-retaining property is remarkably excellent as compared with a conventional winding. This MI cable 10 is used for a winding for driving use of a plunger of a solenoid changeover valve. Thereby, even when dew condensation is caused when this cable is used for a very-low-temperature fluid, a defect of insulation between layers of the winding is not caused; an accurate switching operation can be secured.

IPC: H01L23/28
Filed: 1986-10-22
Abstract: PURPOSE:To relax the concentration of the stress to be exerted on a solder layer used to fix an electrode plate in such a way that the thermal expansion and the concentration of a gel-like filler are absorbed appropriately by an air layer formed in a vacant chamber at the inside of a case. CONSTITUTION:A vacant chamber 10 is formed at the inside surrounded by a side wall of a case body 1 which is sealed by two layers composed of a filling layer 7 made of a gel-like filler and a plastic-sealed layer 8 in such a way that its side (upper part) of said plastic-sealed layer 8 is sealed tightly and that an opening is made at its side (lower part) of the filling layer 7 made of the gel-like material. An air layer is formed inside the vacant chamber 10 in such a way that it can absorb the expansion and the contraction of said gel-like filler due to the change in temperature. In the case of a semiconductor device which is manufactured in this way, the expansion and the contraction of the sealing layer 7 made of the gel-like filler due to the change in temperature at the circumference of the device and due to the heat generated by the device can be relaxed by the vacant layer at the inside of said vacant chamber 10. Through this constitution, it is possible to relax the concentration of the stress by solving a conventional problem that the stress from an electrode plate 6 through the plastic-sealing layer 8 is concentrated on a solder layer 9 located at the upper part of a semiconductor device 4.

Title: Heating controller for cooker
Inventor: KATO TATSUO
IPC: F24C1/00
Filed: 1986-10-23
Abstract: PURPOSE:To reduce temperature ripple and permit cooking with the optimum temperature for a food, by a method wherein the conducting rate of a heating means is controlled by a first set temperature, a trough temperature, a time value through a counting means and the like. CONSTITUTION:The temperature T of cooking area is inputted from a temperature sensitive element 5 and heating is repeated with the conduction rate of 100% until the temperature of a food becomes slightly lower than a first set temperature T0, set by a variable resistor 11, but higher than a second set temperature TL. When the temperature T becomes higher than the temprature TL, time counting is continued while repeating the operation of a heating means 3 until the time T becomes higher than the temperature T0 while the time counting is finished when the temperature T has become higher than the temperature T0. The temperature speed or (T0-TL)/theta1 is obtained from a time value theta and a conduction rate eta with respect to a rated electric power is obtained. Here, the conduction rate etaH, larger than the reference conduction rate eta, and the conduction rate eta, smaller than the same, are obtained and the heating is repeated by the conduction rate eta while the temperature T is higher than the temperature T0, but the heating is repeated by changing the conduction rate etaL to etaH until the temperature T is turned to be risen when the temperature T0 becomes higher than or equal to the temperature T. When the temperature T is turned to be risen, the second set temperature TL is corrected to TL2 and the time counting is started. Here, the temperature T is inputted again and the same operation is repeated when the temperature T has become higher than the temperature T0.

Title: Liquid crystal element and production thereof
Inventor: MOCHIZUKI HIDEAKI
IPC: G02F1/1337
Filed: 1989-09-27
Abstract: PURPOSE:To realize a display state with which bistability is assured and which is uniform and is free from uneveness by using the protein formed by adsorption as the orientation control film of the liquid crystal in a ferroelectric liquid crystal element. CONSTITUTION:A transparent electrode (ITO electrode) layer 12 consisting of an indium tin oxide is formed on a glass or plastic substrate 11. The protein is adsorbed thereon. An important requirement for using the adsorbed protein film as the oriented film for the liquid crystal is that the protein film itself is subjected to an orientation treatment in a specified direction. The orientation treatment method is generally executed by subjecting the surface of the adsorbed protein to the orientation treatment, such as rubbing to form the orientation control film 13. A sealing resin 14 serving also as a spacer is screen-printed by leaving a part thereof as an opening part to be used at the time of injection of the liquid crystal. The oriented film consisting essentially of the protein and the ferroelectric liquid crystal are combined in such a manner. Thus, the liquid crystal element having the good initial orientation performance, switching performance and bistability of memory is obtd.

Title: Vehicular energy regeneration controller
Inventor: NAKAO YORITO
IPC: B60T1/10
Filed: 1999-09-07
Abstract: PROBLEM TO BE SOLVED: To prevent energy regeneration depending upon the drivers' demand from being disabled by an insufficient internal pressure of an accumulator where energy recovery accumulates pressure. SOLUTION: During brakeage, variable displacement hydraulic pump motors 3 and 4 interlocking with the rotation of driven wheels 1 and 2 convert vehicle deceleration energy into oil pressure and pass it to an accumulator 11 for energy recovery. The variable displacement hydraulic pump motors 3 and 4, except during brakeage, on the other, convert oil pressure accumulated in the accumulator 11 into drive energy and use it in driving the driven wheels 1 and 2 for energy regeneration, and at the same time force a controller 16 to decide the internal pressure of the accumulator 11 is below a level sufficient for the energy regeneration, whereupon an electric motor 14 is actuated to feed oil pressure from a hydraulic pump 13 to the accumulator 11 so that the internal pressure of the accumulator 11 is kept not falling below the level sufficient for the energy regeneration.
