Title: Thermo-optical switch
Inventor: KIYONO MINORU
IPC: G02F1/313
Filed: 1984-08-28
Abstract: PURPOSE:To realize an optical switch device of high speed and high integration by constituting it so that a spacer layer is provided on a substrate consisting of a material having excellent thermal conductivity, and a heating element electrode is provided through the second spacer layer on an optical guide formed on the upper part of said layer. CONSTITUTION:Refractive indexes of optical guides 2A, 2B are larger than that of the first spacer layer 5 and the second spacer layer 6 on a substrate 4, therefore, when an optical signal is made incident on the optical guide 2B from a laser diode LD, it goes straight on and is emitted from an optical guide 2Bo of an output side. However, when a heating element electrode 7 is conducted electrically, a cross part of the optical guides 2A, 2B is heated and the refractive index is varied, and the incident signal light is switched to the other optical guide 2Ao. When the electric conduction is stopped, the temperature of the cross part falls, and the course of the signal light is switched again to its original optical guide 2Bo side. In this way, radiation is executed quickly, therefore, the optical switch can be operated at a high speed, and even if it is provided adjacently, an influence on the adjacent optical switches is suppressed.

IPC: F23N5/24
Filed: 1980-12-17
Abstract: PURPOSE: To improve the safety by a method wherein a thermal switch is put in operation by combustion heat and reverse current is rendered to be delivered to an electromagnet and permanent magnet combination type closing valve due to the cooling down of the thermal switch caused by the dying-out off fire owing to some trouble so as to close a gas passage.  
     CONSTITUTION: By turning an ingition knob, a forward current circuit switch 14 is closed and an electromagnet 4 is energized with forward current to attract a permanent magnet 5 to it in order to open the closing valve 8 and to flow gas 2 to ignite. At the same time a timer 15 is put in operation to keep a timer switch circuit 16 open until the contact of the thermal switch 17 is brought into contact by heating. After the elapse of time set in the timer 15, the time switch circuit is closed and a reverse current circuit is ready for operation. When the thermal switch 17 cools down by the dying-out of fire owing to some trouble during combustion, the contact of the thermal switch 17 is closed to form the reverse current circuit and the reverse current is delivered to the electromagnet 4. As a result, the permanent magnet 5 is released from the electromagnet 4 and the closing valve 8 is closed, resulting in shutting-off the gas 2.

Title: Manufacture of semiconductor device
Inventor: OKUMURA YOSHIKI
IPC: H01L21/336
Filed: 1990-07-05
Abstract: PURPOSE:To form respectively a high potential barrier at both ends of a channel region and to improve source/drain breakdown strengths by a method wherein the formation of ion-implanted layers for controlling a threshold voltage is performed by an obliquely rotating ion implantation method using a transfer gate electrode as a mask. CONSTITUTION:Boron ions which are P-type impurity ions identical with those in a semiconductor substrate 1 are obliquely implanted in the whole surface of the substrate 1 from the direction at a prescribed angle of inclination with respect to the direction normal to the substrate surface. Simultaneously with this, the substrate 1 is rotated centering around the normal of the center of a transfer gate electrode 5. By this obliquely rotational ion implantation method, P-type ion-implanted layers 4 for threshold voltage control use are formed using the electrode as a mask. It is desirable to set the angle of inclination for the ion implantation at 15 deg. or larger and 60 deg. or smaller and the ion implantation is normally performed at about 30 deg. or larger and about 45 deg. or smaller. Thereby, the concentration distribution of an impurity subsequent to diffusion can be made high remarkedly in the vicinities of a source and a drain at both ends of a channel region compared to that of the impurity in the vicinity of the center of the channel region.

IPC: B29B17/00
Filed: 1986-07-30
Abstract: PURPOSE:To make it possible to dispose of a combustible waste plastic safely and efficiently without catching fire, by sending a high-temp. superheating steam into a furnace and throwing the waste plastic into the furnace to thermally melt it by the high-temp. superheating steam and thereafter solidify. CONSTITUTION:A wet steam produced by a boiler 1 is sent to a superheating room 2 to superheat at 300-400 deg.C and then discharged downwards out of a spray pipe 3 to heat a furnace 4. After preheating the furnace sufficiently, an inlet door 6 is opened to throw a waste plastic 8 in it through an inlet 5. The melted waste plastic flows into a receptacle 6. As the superheating steam has 10 times energy as strong as a hot air, it can thermally melt the waste plastic efficiently, for its energy as a latent heat of varporization is exchanged with the waste plastic, and not a heat exchange of convection. Moreover, it is safe because a combustible substance never flames in the steam.
