Title: Magnetic marker reader/identifier
Inventor: FUJII HIROSHI
IPC: G01V15/00
Filed: 1992-10-20
Abstract: PURPOSE:To ensure a uniform field region even if a ferromagnetic body is present on the periphery of the reader/identifier by employing only one exciting coil. CONSTITUTION:A rectangular exciting coil 5a is bent upward at the opposite winding parts corresponding to the long sides to form a U-shape and a magnetic marker 1 is passed between the windings on the long sides of the exciting coil 5a at substantially same position as the winding without coming into contact with the exciting coil 5a thus fixing the exciting coil 5a and a planar detecting coil 7 in a magnetic box housing 9. Since the magnetic housing 9 covers a part of a belt 4 which passes through the magnetic housing 9 from one end to the other end thereof, a uniform field is ensured by means of a single exciting coil 5a. Furthermore, since the magnetic housing 9 prevents leakage of the uniform field, field distribution in the housing is not affected by any ferromagnetic body present on the periphery but kept uniformly.

Filed: 1990-10-22
Abstract: PURPOSE:To easily control refractive index, improve heat resistance and decrease effect of OH vibration absorption along with moisture absorption by making both core section and clad section of polysiloxane. CONSTITUTION:A core section and a clad section are both made of polysiloxane. For this reason, plastic light conductive wave passage of various refractive indexes are obtained, and the refractive index is easily controlled.

Abstract: PURPOSE:To prevent the disturbance of an optical system and the decrease of adhesion strength of a spherical lens caused by air bubbles, and increase coupling efficiency, by forming a part in the direction wherein a side section is turned into an inverse mesa shape by etching, in which part the periphery of an engaging hole and the spherical lens are not in contact with each other. CONSTITUTION:A fine spherical lens 3 to thinly focus a radiation beam is mounted on the upper part of an engaging hole 2 by using epoxy based resin 4. As a result, air bubbles which have remained in a part turning to an inverse mesa shape in the engaging hole 2 are discharged outward from a part B where the periphery of the engaging hole 2 and the spherical lens 3 are not in contact with each other, so that the disturbance of an optical system and the decrease of adhesion strength of the spherical lens 3 are prevented, and stable coupling characteristics can be obtained. In particular, as to the optical system, coupling efficiency about 10 percent higher than the conventional ones in which air bubbles are left can be obtained by eliminating the air bubbles. Thereby the disturbance of the optical system and the decrease of adhesion strength of the fine spherical lens caused by remaining air bubbles can be prevented.
