Title: Lens control method for image forming device
Inventor: YAMADA SHUJI
IPC: G03G15/041
Filed: 1988-07-13
Abstract: PURPOSE:To control a lens rapidly and to stop the lens at a reference position accurately by moving the lens at high speed till passing the reference position from a present position and moving the lens in an opposite direction at low speed then stopping the lens at the reference position. CONSTITUTION:In case of the correction on the reference position, first, a zoom lens 24 is moved from an enlargement mode to a reduction mode at high speed, then after passing the reference position, is moved in the opposite direction at low speed in this time, and is stopped at the reference position at the time of switching off a photosensor 30.

Title: Sheet for transcribing buddhist scripture
Inventor: SHIMIZU SHINKICHI
IPC: B42D15/00
Filed: 1997-06-16
Abstract: PROBLEM TO BE SOLVED: To make it possible to easily transcribe Buddhist scriptures without overlapping of the copy of Buddhist scriptures on an outline by printing the copy as a character which can be seen through from the back in an opaque ink of the same color as a translucent sheet on the back face of the sheet. SOLUTION: This sheet 1 for transcribing Buddhist scriptures is a Japanese paper, a machine-made paper or a special paper which is thin and translucent and further, is of a crosswise rectangular shape, and has a rule printed on the front surface. On the back surface of the sheet 1, the copy 4 of the Buddhist scriptures is printed as a character which can be seen through from the back in an ink of the same color as the sheet 1. The copy 4 of the Buddhist scriptures cannot be visually recognized from the front in such a state that the copy 4 is apart from a blotting pad 2. Therefore, the copy 4 is stacked on the blotting pad 2 and thereby the black of the blotting pad 2 is seen through the front face of the sheet 1 and the printed part of the copy 4 is not transparent. Thus only the copy 4 is clearly seen whitely as if it were afloat.  The copy 4 is invisible by parting the sheet 1 from the blotting pad 2, so that the border line is not overlapped even when the outline is shifted and consequently, the transcript is finished neatly.

Abstract: PURPOSE:To prevent a base metal wire from being oxidized and to perform a firm junction by a method wherein a heat shielding plate, which is cooled, is provided on the way of the base metal wire travelling path between the clamper and the capillary. CONSTITUTION:A copper wire 2 passes through the hole 14 of a heat shielding plate 13 in between a clamper 5 and a capillary 6. The air or inactive gas is sprayed on the heat shielding plate 13 from the holes 21 of a nozzle 15 arranged in parallel to the heat shielding plate 13 and the heat shielding plate 13 is cooled. After the wire 2 is led out and is set, a heater 12 is conducted, N2 is made to flow in the nozzle 15 and a junction work is performed. A ball 8 is formed on the point of the wire using a torch bar 7. The ball is pressed by the capillary 6 and a thermocompression bonding, which is applied in combination with ultrasonic waves, is performed under a coation with the heat of the heater 12. Since the cooling plate 13 prevents a clamper 4 and the clamper 5 from being heated and prevents an oxidation of the wire, a favorable pole can be formed on the point of the wire and a firm juctions can be performed.
