Title: Method for forming internal screw part to casting
Inventor: NANJO HIDETOSHI
IPC: B22D19/00
Filed: 1985-11-15
Abstract: PURPOSE:To improve the adhesiveness between an internal screw and casting by screwing an external screw member and internal screw member consisting of a ferrous material having an iron and aluminum alloy layer on the surface, insert-casting the internal screw member in this state into the casting and screwing the external screw member and removing the same from the internal screw member after the casting solidifies. CONSTITUTION:The internal screw member 11 consisting of the ferrous material having the iron and aluminum alloy layer on the surface is screwed to the external screw member 13. The internal screw member 11 is installed into the cavity 15a of a casting mold 15. A molten metal 17 is poured into the cavity 15a and the internal screw member 11 is subjected to insert-casting. The casting is taken out of the casting mold upon solidification of the molten metal 17. The external screw member 13 is then removed by screwing and the internal screw part is thus formed to the casting. The need for a jig for forming the internal screw part is eliminated by such constitution and the adhesiveness between the internal screw member and the casting is improved. The seizure of the external screw member and the internal screw member is obviated.

Title: Fault point locating system
Inventor: MARUYAMA SHIRO
IPC: G01R31/08
Filed: 1990-09-28
Abstract: PURPOSE:To provide an information transmission system which can utilize information efficiently by a method wherein a fault point locating sensor is provided on a gas-insulted apparatus and connected to a substation monitor- control system through a control optical transmission network which is constructed inside a substation. CONSTITUTION:By inputting the information of a fault point locating sensor to the monitor-control system of a substation through an optical transmission network, block division and redundancy of a system such as a system 1 or system 2 can be realized easily. That is, if the fault point locating sensor information were independently inputted to a monitor-control CPU inside the main building of the substation, an optical transmission network would have to be composed of the fault location system only and that would cause system complexity and increase of a cost but, with this constitution, such inconveniences can be avoided and a simple and economical system can be constructed. Moreover, by taking data from the fault point locating sensor into various data of the monitor-control system, the variety of situations of the substation system can be accurately understood and the monitoring accuracy can be improved.

Then, the judgement data is taken out at the same time with the variation start of ordinary patterns, a winning judgement is conducted, and in the case of a big winning judgement, a big winning pattern at the moment of the judgement is displayed on a special pattern display part 3 as a stopped pattern of that time.  Then, when a game ball is mounted on a mounting part while a big winning port 7 is being opened, the big winning port 7 intermittently repeats an opening motion, and after the completion of the big winning state, the variation period of time for the ordinary patterns is shortened until the special pattern is variation-displayed a specified number of times.

IPC: H03K5/151
Filed: 1988-10-14
Abstract: PURPOSE:To detect that clock signals of different phases are simultaneously set to active levels in a short time by respectively adding malfunction detection circuits to final ends of each clock line. CONSTITUTION:In a malfunction detection circuit section 102, an AND/NOR gate G22 and NOR gate G23 constitute a flip flop.
