Title: Metal detector
Inventor: TAKAGI MIKIO
IPC: G01V3/11
Filed: 1980-02-20
Abstract: PURPOSE:To eliminate the dead angles of detection by providing three exciting coils disposed in three directions mutually intersecting and the receiving coils disposed as opposed thereto and driving the exciting coils successively time-dividedly. CONSTITUTION:Exciting coils XT, YT, ZT and receiving coils XR, YR, ZR opposing thereto are disposed on the respective sides of a hexahedron. Part of the outputs of an oscillator 1 are inputted via a synchronizing signal generator 2 to a pulse generator 3, which in turn generates 3 phases of square wave pulse signals. Based on these signals, change-over switches 4 for excitation are driven to excite exciting coils XT, YT, ZT successively time-dividedly. At the same time, change- over switches 6 of receiving signal are driven synchronously to take out the received signals. Thence, a display device 10 is operated by way of synchronous rectifiers 8 and an adder 9. Since the signals are processed synchronously, the dead angles of detection is eliminated irrespective of shapes and directions.

Title: Fail-safe error correction code system
Inventor: TAKAHASHI YUUJI
IPC: H04L1/00
Filed: 1984-02-08
Abstract: PURPOSE:To disable correction to a code with danger-side information and provide a fail-safe by setting a large/small relation between error correction codes previously, and preventing correction from a small signal to a large signal. CONSTITUTION:Circular blank parts in the center are areas where no error occurs and hatched parts encircled specified with dotted circles are area where errors are correctable. Then, only correction to a safety side is allowed as to patterns of transition to the correctable area of a different code among patterns of transition on transmission lines of a code part Fd(x) with danger information and a code part Fs(x) with safety information. For example, when 0 is converted into 0000 and 1 is converted into 1111, the number of each digit constituting 1 is much larger than that of each digit constituting 0. Namely, Fd(x)>F3(x). Thus, an error correction code is constituted and correction from 1 to 0 is allowed while correction from 0 to 1 is inhibited.

Title: Metal pouring nozzle un-opening prevention structure in steel receiving container
Inventor: OSUGI HITOSHI
IPC: B22D41/44
Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of a metal pour nozzle un-opening of a container, into which a metal can be stably poured under a given throughput, by composing at least a portion of a passage closing filler, which contracts with a molten steel, of an iron or an iron alloy granular matter. SOLUTION: A passage r2 of a bottom nozzle 2b and a passage r1 of an upper nozzle 2a are disagreed, and a metal pouring nozzle 1 is in a closed condition. When a molten steel is supplied into a ladle L, an iron granular matter 4 starts to be fused from a portion contacting with the molten metal, and seals over a filler 3 arranged in the passage r1 with the iron granular matter 4 being fused at some extent and solidified. Under this condition, since the filler 3 composed of a sand-like oxide is not sintered, such a bridge that cannot be destroyed by a molten steel static pressure is not formed. In order to supply the molten steel to a tundish, a sliding plate S2 is made to be slid together with the bottom nozzle 2b so that the passage r1 and the passage r2 are made to be agreed.  The filler 3 in the passage r1 drops and discharges the iron granular matter 4 being destroyed by the molten steel static pressure. Thereby, un-opening of the nozzle does not take place.

Title: Automatic screen frame feed device for printing machine
Inventor: TAKASU SHIGEHARU
IPC: B41F15/34
Filed: 1980-02-22
Abstract: PURPOSE: To arrange so that a screen may be fed by one frame under a simple mechanism by fitting an air suction coupler which supplies a compressed air to a printing cylinder mechanism on a screen frame, to an air blow-out coupler and arranging these couplers in an attachable/detachable fashion.  
     CONSTITUTION: If a drive start command from a control panel is issued to a cylinder 14, the cylinder 14 sinks its rod by a fixed length and moves a drive shaft 1 forward with the help of a roller truck 13 by one frame corresponding to one printing on a rail 12. On the way of this movement, an air blow-out coupler 2 is fitted to  a suction coupler 3, so that each pipe is seamed to the other. In addition, a vertical rod 4 is indirectly depressed by further advancing drive shaft 1 through coupler seaming, causing a screen frame B to run forward. If the cylinder rod 14 sank by a fixed stroke, the drive shaft 1 stops its movement, forcing the screen frame B to a halt. The stop position of this screen frame B can be controlled by a stopper mechanism.
