Title: Optical system
Inventor: GOODFELLOW ROBERT CHARLES
IPC: H04J14/00
Filed: 2000-07-17
Abstract: PROBLEM TO BE SOLVED: To provide an optical system, where each add drop multiplexer can provide an add/drop function for a different WDM channel and a plurality of the ADMs are connected in parallel between an optical demultiplexer and a multiplexer for each wavelength multiplex channel, in a switching node in a wavelength multiplex (WDM) communication system. SOLUTION: One of the problems accompanying a present arrangement requires provision of an additional optical switching function, when switching of communication traffic from one optical channel to another is needed. This system provides a branch port to provide interconnection of the ADMs. Thus, a message and data from one of WDM channels are switched to other one of the WDM channels via the existing ADM branch port.

Title: Packaging bag for fruit and vegetable
Inventor: SUNAMURA HIROSHI
IPC: B65D85/50
Filed: 2000-08-28
Abstract: PROBLEM TO BE SOLVED: To keep fruit and vegetable fresh longer. SOLUTION: A bag 10 is formed by folding a polypropylene film so that two layers are opposite to each other and by sealing opposite edges. In the vicinity of one (lower end) of open ends 2 of the bag 10, band-like portions 1 by which the opposite layers are welded together are disposed so as to intermittently extend along two lines that are parallel to the end 2 and so as to form a staggering pattern on the two lines. Uncooked Shiitake mushrooms M are put into such a bag 10 from the other opening 3, and the opening 3 is sealed. An ethylene gas occurring from the uncooked shiitake mushroom M flows out of the bag 10 through spaces between the adjacent band-like adhered portions 1 disposed in the staggering pattern. To the contrary, the band- like adhered portions 1 disposed in the stagger pattern inhibit outside air from flowing into the bag 10.  Thus, decay of fruit and vegetable, which is caused by the ethylene gas and oxidization, can be suppressed.
