Abstract: An optical fiber protective unit includes: a reticulated tube; and a tubular member that is inserted through the reticulated tube and that is configured to accommodate a plurality of optical fibers. The reticulated tube is disposed on an outer periphery of the tubular member in a state folded in a longitudinal direction. Both end parts of the reticulated tube are located on the outer periphery of the tubular member.

Abstract: Provided is a manufacturing method of an axial-type magnetic. The manufacturing method includes a press molding step and an injection molding step. The axial-type magnetic encoder includes a wrap-around binding part wrapping around from a sensor-opposed surface to a back surface of an inward flange part of an annular fixing member. A separated inner peripheral part separated from a rotating body is formed at an inner diameter-side portion of the inward flange part while an outer diameter-side portion of a back surface of the inward flange part is abutted against the rotating body. The inner peripheral part of the annular plastic magnet wraps around to a back surface of the separated inner peripheral part.

Abstract: An axial-type magnetic encoder includes an annular fixing member that is fabricated by press molding, and an annular plastic magnet that is attached by injection molding to a sensor-opposed surface of the annular fixing member. When the annular fixing member includes a cylindrical part and an inward flange part extended radially inward from an end edge of the cylindrical part, the magnetic encoder has a high-form accuracy surface on the sensor-opposed surface more radially outward than a range of a diameter (d?2·r) determined by an inner diameter d of the cylindrical part and a radius r of a corner between the cylindrical part and the inward flange part. An outer diameter of the annular plastic magnet is positioned on the high-form accuracy surface.

Abstract: Provided is a magnetic encoder that improves reliability of binding of the annular fixing member and the annular plastic magnet even when the magnetic encoder is to be attached to an outer ring. An axial-type magnetic encoder 1 includes a wrap-around binding part C wrapping around from a sensor-opposed surface A to a back surface B of an inward flange part 2B of an annular fixing member 2. A separated inner peripheral part D separated from a rotating body 10 is formed at an inner diameter-side portion of the inward flange part 2B while an outer diameter-side portion of a back surface of the inward flange part 2B is abutted against the rotating body 10. The inner peripheral part of the annular plastic magnet 3 wraps around to a back surface of the separated inner peripheral part D.

Abstract: Provided is a magnetic encoder in which the outer diameter of an annular plastic magnet is increased to widen a magnetic force stable region, and a manufacturing method thereof. An axial-type magnetic encoder 1 includes: an annular fixing member 2 that has a cylindrical part 2A attached to a rotating body and an inward flange part 2B extended radially inward from an end edge of the cylindrical part 2A and is fabricated by press molding; and an annular plastic magnet 3 that is attached by injection molding to a sensor-opposed surface of the annular fixing member 2. The magnetic encoder 1 has a high-form accuracy surface (outer diameter FD of a flat surface) on the sensor-opposed surface more radially outward than a range of a diameter (d?2·r) determined by an inner diameter d of the cylindrical part 2A and a radius r of a corner between the cylindrical part 2A and the inward flange part 2B. An outer diameter MD of the annular plastic magnet 3 is positioned on the high-form accuracy surface.

Abstract: Travel information of a target vehicle is stored in time sequence and, on the basis of the travel information and pre-stored travel information of a professional driver's vehicle, a travel position of the target vehicle and a travel position of the professional driver's vehicle are displayed in animation. In such a manner, the driver can visually recognize the travel positions of the displayed target vehicle and the reference vehicle and understand how much the target vehicle is deviated from the ideal travel position.
