Title: Vacuum valve
Inventor: KATO KAZUAKI
IPC: H01H33/66
Filed: 1993-06-02
Abstract: PURPOSE:To prevent reduction in the magnetic force of a permanent magnet by preventing the temperature rise in the permanent magnet provided on the front end of an electrode to give a vertical magnetic field between the electrodes. CONSTITUTION:When opened to open an electric line from a closed condition, a contact plate 6 is rapidly heated by arc discharge generated between the contact plates 6, 6. The front surface of a permanent magnet 10 is brought into contact with the contact plate 6 through a spacer it of small heat conductivity, and the quantity of heat conducted to the permanent magnet 10 is limited to a small level. Since the circumference and the back surface of the permanent magnet 10 are not brought into contact with the wall surface of a storage part 5a, the quantity of heat due to conductive heat is not fed thereto. The temperature increase in the permanent magnet 10 becomes slow thereby. The arc discharge is eliminated in a short period of time, and the temperatures of the contact plate 6 and a conductive shaft 5 are rapidly reduced. The opening operation of a vacuum valve is thus finished without increasing the temperature of the permanent magnet 10 to a large degree.

Title: Optical element
Inventor: YOSHINAGA YOKO
IPC: G02F1/17
Filed: 1986-07-07
Abstract: PURPOSE:To expand the visual field angle of an image screen and to improve distinctness by consisting an optical modulating body of a polymer gel contg. a solvent and fixing a light absorptive exothermic agent in the polymer gel so that the polymer gel exhibits light scatterability when heated and exhibits light transmittability when cooled. CONSTITUTION:The polymer gel perferable as the optical modulating body is formed by the N-alkyl substitution product of a crosslinked poly(meth)acrylamide and water and the light absorptive exothermic agent is exemplified by an electric charge transfer complex and metal phthalocyanines. The non-absorbed light 4 which is not absorbed by the light absorptive exothermic agent is mostly transmitted through an optical element 10 as it is and is radiated from a substrate 1. On the other hand, the (absorbed light) 5 which is absorbed by the light absorptive exothermic agent is absorbed by the light absorptive exothermic agent to generate heat and to heat the substrate polymer, by which the polymer gel is clouded to form light scatterable parts 6 to scatter the non-absorbed light 4. An image 6 conforming to an information source is, therefore, obtd. if the non-absorbed light 4 is projected over the entire surface and the absorbed light 5 is projected as information light to an arbitrary pattern from the same direction or the opposite side of the optical element 10.

Title: Cmos semiconductor device
Inventor: TAJIMA YUTAKA
IPC: H01L27/08
Filed: 1988-06-28
Abstract: PURPOSE:To prevent overvoltage surge from being absorbed from a drain region to a substrate region or a well and increase the strength to latchup by connecting drains of each p or n-type MOSFET between output terminals and each diode in the forward and reverse directions. CONSTITUTION:Diodes 22 and 23 are connected between drain regions 9 and 4 of each p or n-type MOS 13 and an output terminal 15 in parallel with resistor. When positive surge which is higher than power source voltage VDD or more flows in the terminal 15, the diode 22 prevents positive surge from being absorbed from the region 9 of p-type MOS 13 to an n-type substrate region and at the same time, surge escapes to the side of a power source terminal 16 through a diode 24. Further, surge flows from the region 4 of a MOS 7 to a p-type well 2 through the diode 23. However, no latchup takes place in the case where surge is positive. When negative surge which is low electric potential VSS or less flows in the terminal 15, the diode 23 prevents negative surge from being absorbed from the region 4 to the well 2; besides, it escapes to the side of low potential terminal 17 through a diode 25. Moreover, no latchup takes place if surge flowing into the region 9 is negative.
