IPC: B01D53/04
Filed: 1985-12-23
Abstract: PURPOSE:To reduce drop of performance of the titled apparatus due to lowering of temp. without installing any particular device by selecting an adsorbent for N2 corresponding to respective temp. distribution in an adsorption column, and packing each adsorbent in the column in layers. CONSTITUTION:In the titled apparatus comprising plural adsorption columns 2 packed with adsorbent which adsorbs N2 selectively to be used by switching each column, adsorbent 21 for N2 comprising Na-X type, Na-Y type, or Ca-X type zeolite is packed in the inlet side of the feed gas, and adsorbent 22 for N2 comprising Ca-Na-A type zeolite is packed in the outlet side of the feed gas. Since a low temp. zone is formed at ca. 60%(vol) of the column near the inlet side of the feed gas, an adsorbent 21 having high selectivity at low temp. is packed in the low temp. zone at the inlet side, and an adsorbent 22 having high selectivity and large adsorption capacity at room temp. is packed in the high concn. oxygen zone at room temp. at the outlet side. By this constitution, drop of performance due to lowering of atmospheric temp. in winter and inevitable temp. drop of the pressure swinging adsorption method is reduced.

IPC: G03B5/08
Filed: 1987-11-20
Abstract: PURPOSE:To eliminate the need for a camera tripod universal bead by moving an optical sensor itself into a lens focal plane. CONSTITUTION:The optical sensor 2 is arranged on the focal plane of a condenser lens 1 and fixed on a fitting base 3, and a position adjusting mechanism 4 adjusts the position of the lens 1 in the focal plane of the lens 1.

Title: Germ-free adhesive foil for medical preparation
Inventor: WARUTAA HORUTSUAA
IPC: A61F13/02
Filed: 1989-11-09
Abstract: PURPOSE: To provide an adhesive foil which may give an advantageous influence over a medical treatment through its service in giving a medically effective substance to the skin at the part which is to receive a medical treatment. CONSTITUTION: Prior to adhesion to the skin, protective foil 5 is peeled off from adhesive foil 1. Then, adhesive foil itself 1 is adhered to a required part of the skin, whereat pressure-adhered foil 4 serves to keep adhesive foil 1 itself sanitary. Further, as the pressure-adhered foil 4 is kept fastened in place until the time immediately before the syringe needle is pierced into the skin, aspectic- deposited layer 2 is maintained in asepsis all this while. Peeling-off of this pressure-deposited layer 4 may readily be effected without preparing aspectic- deposited layer 2 to cover the entire upper face of the foil 4 itself, with an adhesion-free edge left behind.
