Title: Driving circuit of switching transistor
Inventor: HORIGAMI KOUICHI
IPC: H03K17/04
Filed: 1982-12-10
Abstract: PURPOSE:To attain the reduction in storage time and trailing edge time with less driving power by adopting the back bias current feedback system to a back bias circuit of a main transistor (TR). CONSTITUTION:When the main TR21 is conductive and a TR29 is conductive with a trigger pulse applied to a terminal 33, a voltage is induced in windings 25, 24 of a transformer 23 and the stored charge of the TR21 is discharged as a collector current of the TR29 via the transformer 23. Since the collector current of the TR29 flows to a winding 31 of a transformer 30, a voltage is induced in a winding 32 to supply a bias current to the base of the TR29. Thus, the conductive state is maintained until the stored charge of the TR21 finishes discharge. Then, when a TR27 is made conductive by applying a positive voltage to a terminal 28, the stored charge of the TR21 is discharged at the conduction of the TR27, the TR29 is cut off by cutting off the TR21, then an exciting energy is stored to the transformer 23. When the TR27 is cut off in this state, the TR21 is made conductive.

Title: Removing anchor and method of removing-anchor construction
Inventor: HIRABE TOSHIMITSU
IPC: E02D5/80
Filed: 1995-08-03
Abstract: PROBLEM TO BE SOLVED: To remove an unnecessitated tensile steel material easily by machining a free length section arranged around a cylindrical body in an unbonded manner and using the tensile steel material, in which a fixing length section is not machined in the unbonded manner. SOLUTION: A removing anchor 1 after sheathing operation, etc., is removed by peeling and extracting each PC steel stranded wire 5 of a fixing length section fixed onto a bedrock. The removing space of PC steel stranded wires 5 in the removing anchor 1 is ensured by removing a large-diametral PC steel stranded wires 3 arranged to the axial center of the removing anchor 1. The large-diametral PC steel stranded wire 3 is drawn out easily without introducing large tensile force by machining overall length in an unbonded manner at that time. The PC steel stranded wires 5 of the fixed length section are isolated from a solidifying material in the removing space having a large diameter.  Since tensile force is applied in the direction slipped off from the horizontal direction of each PC steel stranded wire 5, the fixing surfaces of the PC steel stranded wires 5 can be isolated by small force, and all isolated PC steel stranded wires 5 are extracted and removing operation is completed.

The security sheet 22 is configured similarly and its scramble area 26 is arranged in a complementary way to the security sheet 2. The transmitter side sends two images obtained by overlapping the security sheet onto the original.  The receiver side overlaps the security sheet 2 or 22 turned its front side back onto the received image and the result is copied to a transparent sheet while the scrambled characters are erased. The original is restored by overlapping the two sheets.
