Title: Current supplying circuit for high-capacity load driving in integrated circuit
Inventor: KEN MOBUREI
IPC: G11C11/406
Filed: 1992-01-23
Abstract: PURPOSE: To realize a power supply circuit for an integrated circuit memory, suited to a highly capacitive load by combining a current mirror circuit to a constant current source, so as to supply a fixed current at a high current level. CONSTITUTION: When the circuit is turned on, the voltage of a node 14 becomes VCC, and a first transistor 16 is turned off. On the other hand, a second transistor 18 is turned on, because a node 20 is at the ground potential. When the current starts to flow through a resistor 12 from VCC, a voltage at the node 14 drops due to the voltage drop at the resistor 12 for turning on Tr 16. Then as the continuity of Tr 18 is gradually lowered, the circuit becomes balanced so as to make it possible to give a constant current source. However, when the resistance value, etc., of the circuit varies due to the change in temperature, a current mirror circuit is provided so as to compensate this. Thereby, by amplifying a small current it makes possible supplying of an output at a desired high current level.

Title: Optical fiber unit
Inventor: HONSHIYOU MAKOTO
IPC: G02B6/44
Filed: 1989-02-13
Abstract: PURPOSE:To improve the separability between a coated optical fiber and a bundling material and to facilitate connecting operation by uniting a bundled body of silicone resin coated optical fibers with the bundling material of specific silicone resin. CONSTITUTION:The coated optical fibers 3 formed by coating optical fibers 1 with coating materials 2 of silicone resin are bundled into the bundled body 4. This bundled body is united with the bundling material 4 which is made of silicone resin based upon methyl phenyl siloxane containing a phenyl group or diphenyl siloxane. This bundling material resin has different properties from the dimethyl siloxane silicone resin used for the external layers of the coated optical fibers and never comes into contact, so the separability is improved. Further, when the refractive index which is correlative to whether the separability is good or not is set to >=1.42 and <=1.52 by adjusting the content of the phenyl group, excellent separability is obtained.
