Abstract: PURPOSE:To reduce the positional deviation after fixing of an optical fiber and to attain a long-time reliability by fixing a ferrule fixing member and a base material by welding after fixing a ferrule and the ferrule fixing member by welding. CONSTITUTION:A ferrule 4 to which an optical fiber 3 is fixed is inserted to the through hole of a ferrule fixing member 6 put on a substrate 5, and a YAG laser weld zone 7a is fixed with a YAG laser beam 8a by welding after the ferrule 4 is held with a manipulator or the like to adjust the position in the direction of the optical axis and the direction orthogonal to it. A YAG laser weld zone 7c is fixed with a YAG laser beam 8c by welding, and finally, the ferrule fixing member 6 is placed on the substrate 5, and a YAG laser weld zone 7b is fixed with a YAG laser beam 8b by welding after the position is adjusted only in the direction orthogonal to the optical axis. Thus, the positional deviation after fixing of the optical fiber due to the clearance of the through hole of the ferrule fixing member 6 to the ferrule 4 is eliminated to fix the optical fiber with a long-time reliability.

IPC: A46B3/08
Filed: 1993-11-22
Abstract: PURPOSE:To improve resilience, mechanical strength, chemical resistance, thermal resistance, and external appearance by molding polyacetal resin in such a manner that the thickness of a block head, length from the bottom of a bristle-planting hole to the rear surface of the head, and depth of the planting hole are specified according to specific dimenstions respectively. CONSTITUTION:A toothbrush consisting of a block head wherein a bundle of bristles is planted in a planting hole by a flat wire, a block handle, and a slender neck connecting the head and the handle is molded from polyacetal resin. In this case, the thickness of the block head is set 3mm or more and 4mm or less. And the length from the bottom of the planting hole to the rear surface of the head is made 0.2mm or more and 2.2mm or less. Further, the depth of the planting hole is 1.8mm or more. As a result, due to the inherent properties of polyacetal resin, the neck can be made narrow and long, so that elasticity can be given to the neck, whereby operability can be improved and cracks can be prevented from occurring during the planting of bristles.

Title: Magnetic head for vertical magnetic recording and reproduction
Inventor: SUGANO FUMIKO
IPC: G11B5/127
Filed: 1987-12-14
Abstract: PURPOSE:To shorten a distance between a main magnetic pole and an MR element and to ease the influence of spacing loss and azimuth loss by providing the MR element and the main magnetic pole through an insulating layer and an electromagnetic shielding film in the tip part of a head. CONSTITUTION:With providing the MR element 6 and the main magnetic pole 1 through the insulating layer 5 and the electromagnetic shielding film 4, an eddy current occurs inside the electromagnetic shielding film 4, and a magnetic flux thus occurred cancels a magnetic flux leaking from the side of the main magnetic pole 1. Since the magnetic flux passes through the main magnetic pole 1 and a recording return pass part 2 without leaking to the reproducing head but with efficiency, the distance L between the main magnetic pole 1 and the MR element 6 can be shortened. Thus, the influence of spacing loss and azimuth loss can be eased.

Title: Protection system for cross reference object of instruction code
Inventor: YUMIBA HIDEKI
IPC: G06F21/12
Filed: 1986-12-24
Abstract: PURPOSE:To omit a check logic and to avoid the increase of an object by referring to the instruction codes of the same value in place of a constant without generating a constant part and generating an object for the production of the instruction codes. CONSTITUTION:When an instruction code having the same value as that of a constant to which an instruction refers exists, an instruction code is produced so that a constant part is not generated and the instruction codes of the same value are referred to in place of a constant. Thus an object having the complicatedly tangled cross references among instructions is obtained. The performance is never deteriorated owing to the absence of a check logic and the object size is never increased. In addition, the generation of the object can be implemented as an object production algorithm of a language processor such as a compiler. As a result, no special task is required for protection.

Whether or not the measured value is less than a prescribed value N such as 0.4 sec or below is discriminated (S206). When the value is larger than N, it is discriminated that a call signal is a conventional one and a reply message 1 is selected. Otherwise, when the value is smaller than N, the call signal is discriminated as abnormal and a reply message 2 is selected. The reply message read from a memory (S207, 208) is, converted into a voice signal via a MODEM and sent to a telephone line (S209).
