Title: Production of indium-tin oxide sintered compact
Inventor: SASAKI TAKEO
IPC: C04B35/00
Filed: 1994-04-04
Abstract: PURPOSE:To efficiently produce a high density ITO sintered compact at a relatively low firing temp. in a short time. CONSTITUTION:When a mixture of an indium compd. with a tin compd. is compacted and fired in an atmosphere of air to produce an ITO sintered compact, part of oxygen in the air as a firing atmosphere is ozonized and the mixture is fired in an atmosphere of air contg. 100-20,000ppm ozone. Since the progress of a decomposition reaction represented by the formula SnO2 Sn+O2 is prevented by the high oxidizing power of ozone, the sinterability of the mixture is enhanced and the objective high density ITO sintered compact is obtd.

Abstract: PURPOSE:To protect viewer's eyes from being harmed by arranging plural stages near to each other or continuously arranging them and also disposing each stage capable of moving in a horizontal direction so that each stage can be selectively arranged on an illumination position. CONSTITUTION:Two stages 16 and 17 made of transparent glass for placing a film original F on it are freely attachably and detachably disposed on the upper surface of an original placing table 21 in a copying machine 2. And the placing table 21 is moved in the horizontal direction in a state that a new original F for replacing is placed on the stage 17, and then, the original F is arranged on an original illuminating position A. At this time, since each stage 16 and 17 is near to each other, the net original F on the stage 17 is gradually transferred to the illuminating position A in accordance with retreating the projected original F on the stage 16 from the illuminating position A. Then, either of the originals F on each stage 16 and 17 is always positioned at the illuminating position A, so that a screen can be prevented from rapidly becoming dazzling.

Title: Local solder leveling method
Inventor: FUKUDA HIROSHI
IPC: H05K3/34
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To provide a local solder leveling method best suited for narrow-pitch solder connections on a high-density electronic circuit board. SOLUTION: A target solder bump 2a on an electronic circuit board 10 is pressed by an objective top end of an electrode 3 while this top end is energized to heat above the solder m. p. During this heating, the bump 2a is molten to extrude the solder 4 out, wetting up on the side face of the top end of the electrode 3 and separating from a pad pattern due to the surface tension. When the heating current is cut off, the top end of the electrode 3 cools due to radiation to result in a solidified solder deposited on the side face of this top end. Then, the electrode 3 is lifted up, No flux is used during the processing.

Title: Indicator protector for vacuum cleaner
Inventor: KAWAKAMI HIROSHI
IPC: G01F1/28
Filed: 1978-06-01
Abstract: PURPOSE: To ensure that the outside air is sucked in when the negative pressure in a dust collecting box has increased and that a pointer returns instantaneously by providing a connection pipe which bypasses at a position nearer to a cover than the maximum displacement position of the pointer on the movement of the pointer.  
     CONSTITUTION: A connection pipe 30 is so arranged as to bypass a gap 27, which is formed between a pipe 20 and a pointer 21 and a cover 24, to a position nearer to the cover 24 than the maximum displacement position of the pointer 21. During cleaning, with a filter clogged or with suction means closed, the pointer 21 moves. From this time on, air flows into the pipe 20 through the connection pipe 30. When the pointer 21 has gone beyond the fitting position of the pipe 30, air does not flow in the pipe 30 and the pointer 21 moves to the maximum displacement position at a stroke. With the suction means released from closure, the pointer 21 returns instantaneously. Thus there is provided an indicator protector of good performance  capable of swift movement.
