Inventor: FUJIOKA TETSUYA
IPC: H04N1/04
Filed: 1998-10-28
Abstract: PROBLEM TO BE SOLVED: To improve the efficiency by decreasing a first scanning time. SOLUTION: When a book original BO is placed on a book original platen 105 of a book tray 103 and the book tray 103 is pushed into a scanner main body and set, a carriage 200 immediately starts preliminary scanning to detect ends of left and right pages of the book original BO. Then the carriage 200 stops around a file margin of the book original BO and reaches a standby state. When a scanning instruction is received, the carriage 200 quickly moves to the read start position based on the page end position data obtained at the preliminary scanning to start reading.

Title: Method for recovering metal from printed circuit board
Inventor: SHIINO TORU
IPC: C22B7/00
Filed: 1996-11-20
Abstract: PROBLEM TO BE SOLVED: To easily recover solder and metal from a printed circuit board and to reutilize them by removing the oxide film on the surface of the soldered part of the board with a metal oxide film removing agent and then heating the board above the m.p. of the solder. SOLUTION: The entire printed circuit board is heated above the m.p. of the solder to melt the solder. In this case, the oxide film formed on the solder surface is previously removed by using a metal oxide film removing agent such as rosin-base resin acid. Consequently, the molten solders are again brought into contact with each other and fused together into a larger lump, and the parts packaged in the board are easily separated from the board. Further, when the board is crushed or pulverized and then treated as stated above, the conductor metals and the solders are more easily fused together, the grain shape of the metallic component is strikingly different from that of the resin, and the solder and conductor metal are easily separated from the board.

Title: Tapping screw
Inventor: ZAIKI MASAMI
IPC: F16B25/00
Filed: 1997-10-24
Abstract: PROBLEM TO BE SOLVED: To provide a tapping screw which can generate a certain fastening force by decreasing the imperfectly threaded portion on the screw leg in its part nearer the head and making it possible to drive into a comparatively thin work. SOLUTION: A material 1 for screw is composed of a head part 4 and a leg 2 formed in a signal piece therewith, and a trunk 3 having a slightly greater diameter than the leg 2 at its forefront is formed on the leg 2 on its side continued to the head 4, and threads are formed by rolling on the leg part 2 including the trunk 3, and thus a tapping screw is accomplished, wherein the threads on the part near the head engage certainly a thin work because the imperfectly threaded portion having lower thread height than the perfectly threaded portion in the center of the leg 2 is decreased in the threads formed in the leg part 2 near the head 4, and there is no risk that the threads of the work are crushed by the fastening force. Because threads are formed over the whole leg 2 including the trunk 3, the material can fill a thread forming groove in a rolling die, and it is practicable to make tall the threads sufficiently.
