Title: Optical fiber cord holding structure
Inventor: KUROJI NORIO
IPC: G02B6/36
Filed: 1979-02-17
Abstract: PURPOSE:To obtain the optical fiber holding structure which gives the connection stable against temperature change and external force by containing and holding an optical fiber strand in an elastic material holding member having a curved through- hole. CONSTITUTION:A fiber strand 1 is secured to a terminal member 4 by adhesive material 3. An elastic optical fiber holding member 10 which has a curbed through- hole 11 and a space capable of containing a core wire 2 in the inside is secured to the terminal mamber 4 by means of an adhesive agent 12, the fiber strand 1 being passed through the inside of the through-hole 11. A tension-resistance member 5 is held secured to the holding member 10 by a clamping member 7. As against a temperature change in this state, the protrusion of the fiber strand owing to the shrinkage of the core convering may be absorbed by the deflection that the strand 1 can take within the curved through-hole 11. When tensile force is applied upon the fiber cord 8, the holding member 10 elongates and is able to adsorb the tensile force. In this way, the connection stable against temperature change and external force may be accomplished.

Inventor: KASUGA MASAO
IPC: G06F7/544
Filed: 1981-02-09
Abstract: PURPOSE:To prevent the generation of a noise due to an overflow by performing level clipping operation when an input digital signal overflows. CONSTITUTION:When a signal of the MSB of the output digital signal of a holding circuit 6 and a signal of the 2nd bit one bit higher than a bit constituting the 2nd bit of a final output differ in sign, an overflow occurs and the output signal of an exclusive OR circuit 13 has logic 0, so a data selector 14 performs switching to output a signal having a different sign from the MSB from an inverter 11 to input terminals A1-An-1. Thus, the overflow is detected securely to perform clipping without level variation, thereby preventing the generation of a noise.

IPC: H01F1/06
Filed: 1988-01-28
Abstract: PURPOSE:To obtain magnetic powder having minuteness together with high coersive force by making a molten metal flow to an inert gas flow per fixed period at a prescribed weight ratio.
