Title: Device for limiting speed of vehicle
Inventor: TAKASUGI KAZUHIDE
IPC: B60K31/18
Filed: 1988-05-19
Abstract: PURPOSE:To prevent a vehicle speed limiting means from operating during the stoppage or acceleration of a vehicle by adding the monitoring of engine speed to the conditions for operating the vehicle speed limiting means. CONSTITUTION:A comparator 30 as an idling detecting means detects that an engine 10 is at a speed above an idling speed. A timer circuit 36 outputs an A signal when the idling speed continued for above a certain time according to the output of the comparator 30, a vehicle speed discriminating means 42 outputs a B signal when a vehicle speed is within a defined speed range, and a comparator 54 as a maximum engine speed detecting means outputs a C signal when the engine speed is above a defined maximum speed. An AND circuit 58 outputs a vehicle speed limiting signal D on condition that all the A, B, and C signals are outputted to operate a vehicle speed limiting means. Thereby, a vehicle speed at which a vehicle is actually traveling at above the maximum speed can be surely distinguished and discriminated from racing in a stopped condition or accelerating.

Title: Playing machine
Inventor: UGAWA SHOHACHI
IPC: A63F7/02
Filed: 1990-05-09
Abstract: PURPOSE:To allow a worker of a game house to rapidly deduce the cause of operation failure of an electric playing device by judging that the voltage of the power supplied to the electric playing device is lowered below a preset determined voltage value by a voltage lowering judging means, and communicating this by a communicator means. CONSTITUTION:A power source circuit included in a common circuit base has a low voltage judging circuit, which mainly comprises a PUT(programmable unijunction transistor) 34, a Zener diode ZD35, resistances R3, R4, R10, a LED 36, and a capacitor C12. When the voltage is lowered below a determined value, the PUT 34 is turned ON, and the LED 36 is turned ON to perform luminous indication. It is judged by the PUT 34 that the voltage value of the power, supplied to an electric playing device, is lowered below a preset determined voltage value. When the LED 36 emits lights, a lower voltage indicator part 18 is lighted and indicated to indicate a reduction in the power for operating the electric playing device.

Title: Boat loader
Inventor: NAGATOMO HIROTO
IPC: H01L21/677
Filed: 1979-09-21
Abstract: PURPOSE:To permit a boat to be inserted into a process tube without touching with its inner wall by allowing the boat to swing about the mounting portion of the boat loader driving unit by the vertical movement of the lever holding one end of the boat. CONSTITUTION:A boat loader driving unit 9 is placed at a position so that a boat 10 never touches with the inner wall of a process tube, and the boat 10 is inserted into the process tube by the rotation of a moving motor 22. When a wafer 12 reaches the central position in the longitudinal direction of the process tube, the motor 22 stops and a swinging motor 30 starts rotation. A swinging cam 29 and a lever 28 cause the boat 10 to swing about a rotating shaft 24. The motor 30 stops when the bottom surface of the periphery of the boat 10 touches with the bottom surface of the inner wall of the process tube. The constitution permits the horizontal delivery of the boat 10 to be ready, because the boat 10, which is held by a boat holding plate 14 of the boat loader driving unit and a roller 26 on the process tube side, has a longer interfulcrum distance. Consequently, the inside diameter of the process tube is unnecessary to enlarge, and the boat 10 can be inserted into the process tube without touching with its inner wall.

IPC: C01B31/02
Filed: 1985-06-04
Abstract: PURPOSE:To produce carbon electrodes for already fired type aluminum smelting with reduced content of metal impurities, by adding an inorganic fluoride to a specific stage in kneading a carbonaceous material consisting of aggregate and binder, molding the kneaded material and firing the molded material. CONSTITUTION:A suitable aggregate raw material is sieved or aggregate raw materials previously sieved to the respective particle size are incorporated at a specific proportion, and the resultant material is normally preheated. A carbonaceous binder is then added thereto, and the mixture is kneaded while heating and then molded and fired. In the above-mentioned series of steps, an inorganic fluoride, e.g. NH4F, NH4F.HF or AlF3, is added thereto before the molding step thereof. The time of adding the inorganic fluoride is not particularly limited if it is before the molding step, but preferably the inorganic fluoride is added in the kneading step, particularly in the kneading step of only the aggregate before adding the binder. The addition of the inorganic fluoride permits the reduction in content of metal impurities in the finally obtained already fired carbon anode.
