摘要:
Provided are a receptacle attached with an optical isolator and a manufacturing method thereof, capable of easily performing position alignment among an end surface of a magnet, an end surface of a fiber stub, and a polarization plane of a polarizer and dimension calculating of the optical isolator without an increase in the number of parts. The optical isolator is constructed by fitting a fiber stub into which an optical fiber is inserted and of which end surface is formed to be slanted with a predetermined angle into a ferrule holder, by forming an end surface of the magnet to be slanted with the same angle as the predetermined angle, and by fixing the optical isolator element to the magnet. The receptacle attached with an optical isolator is constructed by integrally fixing the optical isolator to the end surface of the fiber stub by fitting the optical isolator into an inner diameter portion of the ferrule holder.

A transmitting/receiving unit receives vehicle information including type and speed of a vehicle and position information about present position of the vehicle sent from a terminal device carried on the vehicle. A vehicle control information generating unit generates vehicle control information for controlling vehicles statistically formed for each type of vehicle on the basis of the vehicle information and the position information. A storage unit stores the vehicle control information. On the basis of position information sent from the terminal device, the vehicle control information with respect to the traveling direction of the vehicle is sent to the terminal device from the storage unit and the traveling of the vehicle is thus controlled.

The purpose is to obtain efficiently, from a large piece of flat optical material, flat optical elements that allow for miniaturization of optical devices because they are octagonal, and that can be fixed securely in the inner opening of permanent magnets by brazing. Rounded openings 11, 12 . . . that are circular or elliptical in shape are made at intersections P1, P2 . . . of the cut lines C1, C2 . . . at which flat optical material 10 is cut vertically and horizontally; the flat optical material 10 in which the openings 11, 12 . . . have been made is cut vertically and horizontally; and a number of flat optical elements, each with a nearly octagonal outline with sides that are alternately four straight lines and curves, are obtained.
摘要:
A process for preparing a dialdehyde which comprises subjecting a glycol to oxidation-dehydrogenation in the presence of silver particles of which the surface is partially coated with a silicon carbide powder or a silicon nitride powder. According to the present invention, dialdehydes can be prepared from glycols in high conversion of the glycol in high selectivity into the dialdehyde, and the silver catalyst can be reused even if the reaction is stopped in a while since the silver particles are not aggregated during long time operation.

Provided are an awakened-state maintaining apparatus and an awakened-state maintaining method that maintain an awakened-state of a driver. In the awakened-state maintaining apparatus (100), a visual-stimulation control unit (107) calculates an initial displaying position that is in accordance with the product of initial setup time and detected vehicle speed. A displaying means displays on the initial displaying position a visual stimulation image pertaining to a visual-stimulation virtual object that will evoke an awakened-state, and also updates the visual stimulation image using a visual effect wherein the visual-stimulation virtual object is displayed so as to seemingly approach the vehicle at the detected speed, in accordance with the time elapsed since the visual stimulation image was first displayed. An audio signal control unit (105) outputs an audio signal and a vibration control unit (106) outputs a vibration, when the initial setup time has elapsed since the visual stimulation image was first displayed. Since, in such a way, a driver is able to sense that the vehicle that he/she is driving has run over the visual-stimulation virtual object, which was displayed so as to seemingly make a gradual approach to the vehicle, with his/her visual, hearing, and tactual senses, the awakened-state of the driver is able to be maintained.
摘要:
A guide system for delivering data between a guide apparatus and a terminal without installing a data carrier reader. This guide system comprises a guide apparatus and a radio apparatus that is a terminal communicating with the guide apparatus. In the guide apparatus, guide data is generated on the basis of conditional data transmitted from the radio apparatus, the guide data is transmitted to the radio apparatus, and the conditional data is received from the radio apparatus. The radio apparatus comprises a communication unit which receives the guide data generated by the guide apparatus and transmits the conditional data to the guide apparatus. Thus, the radio apparatus receives and utilizes the guide data transmitted by the guide apparatus.
