Title: Lubricating device
Inventor: NAKADA MIKIO
IPC: B67D7/04
Filed: 1987-12-03
Abstract: PURPOSE: To prevent the deterioration of a hose even when the hose is pulled out by the maximum legal length for feeding, by winding a feeding hose in a hose case mounted on an upper portion of an oil feeder case and feedably storing the same. CONSTITUTION: A feeding hose 15 is wound on a take-up reel 13 when the hose is not used, and a feeding nozzle 16 is located on an upper position nearest to a hose case 4. When the oil feeding is performed at an oil feeding area A or B of an automobile, a down stitch SW1 mounted on the feeding nozzle 16 is turned ON by stretching an arm upward, whereby a reel motor 17 is normally rotated by the operation of a controller 11, as a result the take-up reel 13 is normally rotated, the feeding hose 15 wound on the same is fed out downward through a slot 14, and the feeding nozzle 16 is lowered. When the feeding nozzle 16 is lowered to the desired feeder height, the down switch SW1 is released, whereby the reel motor 17 is stopped, and the feeding nozzle is stopped at that position.  That is, the feeding hose 15 can be fed out by the length suitable for the feeding, and the hose 15 is not excessively fed out, so that the damage of the hose 15 can be minimized.

Inventor: NAKAMURA SACHIKO
IPC: H01L23/50
Filed: 1997-11-10
Abstract: PROBLEM TO BE SOLVED: To safely, efficiently and stably regenerate a waste liquid of a copper etching soln. containing an org. acid and cupric ion by bringing the copper etching waste liquid into contact with an acid phosphate or oxime extracting agent to extract and remove copper. SOLUTION: As the org. acid used for a copper etching liquid, formic acid, acetic acid or the like is used. An acid phosphate extracting agent is especially effective when the waste liquid is an acid soln., and for example, a diarylphosphate such as dioctylphosphate and didesilylphosphate are preferably used. An oxime extracting agent is especially effective when the waste liquid is an acid soln. or neutral soln. An oxime compd. expressed by the formula shows high extracting performance for copper. In the formula, R1 , R2 are each a hydrogen atom or hydrocarbon groups, and one of them has a hydroxyl group in its skeleton. By extracting and removing copper in the extracting agent waste liquid with sulfuric acid, the extracting agent can be reused.

Title: Picture drawing device
Inventor: NAKAMURA KAZUO
IPC: G06T11/20
Filed: 1989-11-27
Abstract: PURPOSE:To always select the nearest line to the line brought to picture drawing even in the case of reduction picture drawing by providing an approximating means for approximating two points to an integer value, and an arithmetic means for calculating a picture drawing coordinate between them, based on a prescribed algorithm by using to points before approximation. CONSTITUTION:At the time of executing reduction picture drawing, a divider 18 divides a coordinate value contained in coordinate information given from a CPU 12 by a reduction rate, rounds off 5 bits or below of its decimal place, and gives a value of 4 bits below the decimal place to a picture drawing device 11. The picture drawing device 11 receives this information and generates successively a coordinate of a point brought to picture drawing by a picture drawing coordinate generator 15. Accordingly, when the coordinate information shown by a value containing a number of the decimal place or below is inputted as the case of reduction picture drawing, a picture drawing coordinate between a start point and an end point is calculated, based thereon. In such a way, comparing with the case of calculating the picture drawing coordinate by using a value being approximate to an integer as usual, an approximate error decreases, and even in the case of reduction picture drawing, a picture drawing point being near a line brought to picture drawing can always be selected.
