IPC: H04N7/16
Filed: 1997-06-05
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration of a system even if the emergency situation in a disaster and the like occurs by collectively supplying power to plural nodes connected to the center station of CATV through an optical fiber transmission line. SOLUTION: The center station 10 supplies AC 100 V to respective systems, namely, a CATV head end unit part, ant optical transmission part and a power supply system part, for example. A non-power cut device collectively supplies power by a commercial power source and collectively supplies power by the backup power of self-power generation at the time of power cut owing to the disaster. A branch part 30 branches one power cable into two power cables and connects the respective optical nodes in a loop form. The respective optical nodes are arranged in respective refuges at the time of the disaster one by one. Then, optical communication with the center station 10 is realized by collective power supply.  The branch part 30 controls the change-over of a switch in accordance with the instruction of the center station 10 and supplies power clockwise and anticlockwise from the center station 10 into the self-device and the respective optical nodes.

Title: Refill
Inventor: KASAHARA HIROYUKI
IPC: B43K7/02
Filed: 1999-05-27
Abstract: PROBLEM TO BE SOLVED: To externally discriminate an ink color by forming a highly transparent portion having better transmittance than the other portion of a light through an ink at a part of a pipe portion. SOLUTION: A small mount ink storage portion 15 is formed as a highly transparent portion in which a channel width is narrowed by collapsing a pipe portion 12 near a tip 11 at the portion 12. In this refill, since transmittance of a light 16 transmitting an ink layer of the portion 12 at a position of the portion 15 becomes good, a color discrimination of the ink contained in the portion 12 can be facilitated. Accordingly, it is not necessary to execute coloring of the same color as that of the ink at a writing instrument body for mounting the refill or a grip portion, and hence a manufacturing cost of the instrument can be reduced. Since a color discrimination of the refill itself can be conducted and facilitated, it can be easily avoided to erroneously mount the refill of different color at the body when the refill is used as a replacing refill.
