A train speed control systemincludes a first non-contact sensorthat outputs measured first speed information, a first safety devicethat receives the first speed information from the first non-contact sensor, a second non-contact sensorthat outputs measured second speed information, and a second safety devicethat receives the second speed information from the second non-contact sensorand transmits the received second speed information to the first safety deviceat a predetermined timing. Then, when first second speed information is received from the second safety device, the first safety deviceevaluates soundness of the first speed information based on a speed difference between the first second speed information and first first speed information measured by the first non-contact sensorat substantially the same timing as the first second speed information, and determines control speed of a trainbased on a result of the evaluation.

A reinforcing sleeve for collectively reinforcing spliced portions of a plurality of optical fiber core wires disposed side by side includes a heat-shrinkable tube, a heat-meltable member, a tension member, and so on. The tension member and the heat-meltable member are inserted into the heat-shrinkable member. A thick portion is provided at a substantially center portion of a width direction of the heat-meltable member. Thus, on a cross section perpendicular to a longitudinal direction of the heat-meltable member, an amount of the heat-meltable member at proximity of the center portion of the width direction of the heat-meltable member is greater than an amount of the heat-meltable member at proximity of the end portions of the width direction of the heat-meltable member. This forms a flow of the heat-meltable member from the center portion toward the end portions in the width direction at the time of melting the heat-meltable member.

A reinforcing sleeve is a member for collectively reinforcing spliced portions of a plurality of optical fiber core wires disposed side by side. The reinforcing sleeve includes a heat-shrinkable tube, a heat-meltable member, a tension member, and so on. The heat shrinkable tube is a cylindrical member having an approximately circular cross section. The tension member and the heat-meltable member are inserted into the heat-shrinkable tube.

There are provided an object recognition apparatus that raises the recognition accuracy for a surrounding object and a vehicle control apparatus, and an object recognition method and a vehicle control method. An object recognition apparatus receives object data, which is a state value of the object, from a first sensor for detecting a surrounding object; compares estimation data obtained through estimation of a state value of the object, based on recognition data calculated in a past period, with the object data, and determines whether or not the object data is data in a low-resolution state; then, in accordance with the determination result, calculates the state value of the object by use of object data and estimation data and then generates the state value as recognition data, so that the recognition accuracy for an object is raised.

Object recognition apparatus, vehicle control apparatus, object recognition method, and vehicle control method

In this object recognition device, an association between a first object detection result and a second object detection result is taken in a region excluding an occlusion area. When the first object detection result and the second object detection result are determined to be detection results for an identical object, a recognition result of the surrounding object is calculated from the first object detection result and the second object detection result. Thus, occurrences of erroneous recognition of an object can be decreased as compared to a conventional object recognition device of a vehicle.

The main body part is a substantially cuboid member in which an optical fiber is disposed. One width-direction side of the main body part is provided with a lid part capable of opening and closing with respect to the main body part on a hinge. An installation part on which an optical fiber or the like is disposed is formed on the upper surface (the surface facing the lid part) of the main body part. The installation part comprises a reference surface and a recessed portion that is formed closer to the distal-end side than is the reference surface and that is formed at a lower position than is the reference surface. The reference surface is a region where the optical fiber or the like is pressed down by a pressing part. The recessed portion is a region where a drop cable is pressed in by a pressing part.

Optical-fiber-holding member, and fusing device

An optical fiber placement surface has formed thereon width-directional position restricting sections for partially restricting the position of an optical fiber ribbon in a width direction perpendicular to the axial direction of the optical fiber ribbon. A portion other than the width-directional position restricting sections serves as a width-directional position non-restricting section that does not restrict the position of the optical fiber ribbon in the direction perpendicular to the axial direction of the optical fiber ribbon. A pressing member is formed at a portion corresponding to the width-directional position non-restricting section. On the other hand, the pressing member is not formed at positions corresponding to the width-directional positional restricting sections. Thus, the optical fiber ribbon is not pressed at the width-directional positional restricting sections. Portions at which the optical fiber ribbon is not pressed by the pressing member are defined as non-main pressing sections.
