Title: Oxygen enricher
Inventor: ICHIKAWA KOJI
IPC: C01B13/02
Filed: 1995-09-11
Abstract: PROBLEM TO BE SOLVED: To improve oxygen enriching efficiency by providing an automatic stop valve between an adsorption bed for adsorbing the nitrogen in supply air and a surge tank for storing an oxygen-enriched gas and intermittently opening and closing the valve during the adsorption stage. SOLUTION: Air is supplied from a compressor to an adsorption bed packed with an adsorbent (e.g. molecular sieve zeoplite 5A) capable of adsorbing nitrogen in preference to oxygen. The gas enriched with oxygen in the bed is transferred to a surge tank through a duct provided with an automatic stop valve and stored. In this case, the automatic stop valve is intermittently opened and closed by a control unit while air is supplied to the bed in the adsorption stage. Consequently, the contact time of nitrogen with the adsorbent is prolonged in the adsorption stage, nitrogen is more efficiently adsorbed, and the adsorption equilibrium as the basic performance of the adsorbent is approached sooner. Accordingly, the amt. of oxygen remaining in the gas phase is increased, and the recovery of the oxygen-enriched gas is enhanced.

Title: Method and device for automatically pressing object against another object
Inventor: MISUMI KENJI
IPC: H02P29/00
Filed: 1994-09-28
Abstract: PURPOSE: To reduce the impact force when an object to be moved is brought into contact with an object to be contacted and, at the same time, to shorten the time required to obtain a force required for pressing the object to be moved against the object to be contacted (to position the object to be moved). CONSTITUTION: After a needle 5 (object to be moved) is brought into contact with a substrate CB (object to be contacted) by moving the needle 5 together with a needle holder 4 by means of a motor 12, the needle 5 is pressed against the substrate CB by further causing the motor 12 to generate a prescribed torque. A control command generating means 14 gives a speed command to a motor controller 13 to reduce the speed of the needle 5 to an allowable value Vb or lower until the needle 5 comes into contact with the substrate CB. When the speed of the needle 5 becomes equal to or lower than the allowable value Vb, the means 14 gives another speed command to again reduce the speed of the needle 5 after the speed is increased. Therefore, the motor 12 can generate the torque required to press the needle 5 against the substrate CB in a short time.
