Patent CA-2091820-A1 (CA)
Title: Optical telecommunication method
Inventor: BIOTTEAU BERNARD
IPC: G02B6/00
Filed: 1993-03-17
Abstract: A phase-modulated carrier wave is injected by a laser semiconductor source (8, 10) into a line fibre (4) in order to carry digital information to be transmitted. An optimal value of a continuous parameter of this carrier wave, in particular its phase excursion, is to be redefined now and then owing to drifting of the characteristics of the source. This is done based on the variations in the power of a diffracted wave which is returned via this fibre by Brillouin effect in response to an incident wave emitted for this purpose by the same source. Application to telecommunications networks. <IMAGE>

Title: Ultra-high purity nitrogen and oxygen generator
Inventor: NAGAMURA TAKASHI
IPC: F25J3/04
Filed: 1993-03-26
Abstract: A generator produces ultra-high purity nitrogen and ultra-high purity oxygen simultaneously by the liquefaction and rectification of feed air. Feed air is rectified in a first rectification column (4), and nitrogen gas separated to the column top thereof is liquefied, in a nitrogen condenser (8), by oxygen-enriched liquid air separated to the bottom portion of the first rectification column. The oxygen-enriched liquid is fed to the upper portion of a second rectification column (5) having a reboiler (5a) in its column bottom, so that through its rectification in the second rectification column oxygen gas is fed from above a liquid reservoir to the lower portion of the third rectification column (6).  Through the rectification of the oxygen gas in the third rectification column, high purity oxygen gas, from which impurities having higher boiling points than that of oxygen have been removed by liquefaction, is fed to the center portion of the fourth rectification column (7) having a condenser (7e) in its top portion and reboiler (7a) in its bottom portion. Through the rectification of the high purity oxygen gas in the fourth rectification column, impurities having lower boiling points than that of oxygen are exhausted from the top portion thereof as non-condensed gas and ultra-high purity liquid oxygen is separated to the column bottom thereof.

Inventor: OTSUKA YUZO
IPC: B29C65/22
Filed: 1994-05-06
Abstract: There is provided a heat sealing bar (19) having a heating ribbon (35) which endures repeated sealing operations.  The heat sealing bar comprises a slender block-like bar body (31), an insulating layer (33) formed on the surface of the bar body (31), and a heating ribbon (35) fixed on the insulating layer (33).  A heat pipe (41) is embedded in the bar body (31) along the heating ribbon (35).  The heat pipe (41) transfers heat in the longitudinal direction of the heat sealing bar (19) from a portion of a small thermal load to a portion of a larger thermal load, thereby holding the entirety of the heat sealing bar uniform in temperature.  Accordingly, the opposite ends and central portion of the heating ribbon (35) fall in a stationary state in the same temperature range as that for the rest of the heating ribbon.  As a result, the heating ribbon (35) expands uniformly over the entirety thereof, and there never occurs the phenomenon of an inconsistency in expansion between the heating ribbons (35) and the insulating layer (33).
