An optical path blockage detecting device includes optical conductive members located between light emitting elements and light receptor elements and extending parallel to optical paths defined between the light emitting and receptor elements. Each optical conductive member is combined with a light absorbing member which absorbs undesired beams of light so as to improve the optical directivity of incident light and improve the signal-to-noise ratio of the device.

A gap between end surfaces of optical converters provided at the ends of optical guide paths of optical fibers is maintained with a high accuracy and thereby optical coupling efficiency of such optical converters can be improved with an optical fiber connector comprising a plug engaging member at the end of optical guide path and a plug which is removably engaged with said plug engaging member having the structure that a spacer is provided between both surfaces of said optical guide path ends, an optical guide path hole is formed to said spacer and a constant gap is formed both end surfaces of optical converters provided at the surface of said optical guide path ends through said optical guide path hole.
摘要:
A touch-panel input device of the photoelectric system where a ray scans above a display face of a display unit. Respective coordinate values directed by bringing a finger tip onto the display face are detected by means of interrupted rays and displayed successively on the display face in the form of an index. The detected coordinate values are input into a processor unit when switching means is pushed by the finger tip.

A welding process using a laser beam for joining metals such as steel plates along a see-through groove 10 such as a square groove formed by laser welding between opposed edges of the two metals is disclosed, in which a filler wire 9 is supplied to the see-through groove 10 as shown in FIGS. 3a, 3b and 4 to increase the permissible gap of the see-through groove. A spot 11 of laser beam 1 with a power density of 5.times.10.sup.5 w/cm.sup.2 or above is formed in the see-through groove 10 on the same level as the surface of the metals 3. The filler wire 9 is inserted into a point coincident with the spot 11 of the laser beam 1, or the spot 11 of the laser beam 1 is formed on top of the filler wire 9 in the see-through groove 10. As the filler wire 9 is melted by the laser beam, a globule or droplet formed is formed from it and proceeds to and deposited on the opposed edge faces 12 defining the groove 10 to heat the edges 12 to effect welding.
摘要:
An azimuth determinating apparatus wherein the azimuth sensor is oriented to a specified direction, and the deviation of the two-component detection signals of the azimuth sensor from the pointing direction of the azimuth sensor are corrected by the adjustment of the two-component detection signals with the adjusting circuit in accordance with the indication on the amount of deviation indicated by the indicating circuit, whereby distortion of the output signals due to the residual magnetism of the azimuth sensor is corrected and the true azimuth can be determined.
摘要:
An accelerator pedal device for a vehicle, performing a pedal reaction force control method. The accelerator pedal device is provided with an engine speed detection unit that detects the engine speed (Ne) and a reaction force control unit that controls, on the basis of the engine speed (Ne), a pedal reaction force (Fr) applied by a reaction force application unit. The reaction force control unit limits the reduction ratio of the pedal reaction force (Fr) when the reduction ratio of the engine speed (Ne) is greater than or equal to a predetermined value.

摘要:
A single can-type composite heat source machine including a single can body including a first combustion section having a first burner and a hot water supplying first main heat exchanger located above the first burner, and a second combustion section having a second burner and a second main heat exchanger located above the second burner and used for a purpose other than hot water supply. The first combustion section and the second combustion section are partitioned from each other by a partition wall and juxtaposed in a lateral direction. The machine includes a first auxiliary heat exchanger and a second auxiliary heat exchanger both of a latent heat recovery type connected to upstream sides of the first main heat exchanger and the second main heat exchanger, respectively. An exhaust system can be miniaturized and simplified in spite of provision of the auxiliary heat exchangers.
摘要:
A steering system for rear wheels of a vehicle without a dead zone in the vicinity of the steering wheel zero. The steering system includes a steering controller and control units that control the rear wheels to be steered in accordance with the steering angle of the steering wheel. The steering system performs a reduction control to provide a smaller steering control amount for the rear wheels in a range where a steering angle becomes smaller than a predetermined value, compared to a steering control amount for the rear wheels in the other ranges of the steering angle. When an angle speed of the steering angle becomes greater than a predetermined value, the steering system performs no reduction control or the reduction control with less reduced steering control amount for the rear wheels even in the range where the steering angle becomes smaller than the predetermined value.
