Title: Vehicle detecting device
Inventor: YONEMURA TAKAMOTO
IPC: B60R21/00
Filed: 1999-02-02
Abstract: PROBLEM TO BE SOLVED: To accurately determine the detection range of a preceding vehicle even in night-time driving or the like by determining a range for detecting the preceding vehicle based on a side position or the like on the road of an own vehicle. SOLUTION: A range for detecting a preceding vehicle is determined based on a side position or the like in the road of an own vehicle. More specifically, left and right detection ranges θL and θR of the vehicle are determined by a width W of a lane (own lane) where the own vehicle is driving, a distance P where the vehicle deviates from the center of the own lane, and a distance L to the preceding vehicle, thus determining a detection region from one end of the own lane to the other with a radar of a thin beam and hence improving the detection accuracy of the vehicle in the own lane. An own vehicle side position detection part detects a side position in the road of the own vehicle based on the shape (especially, the position of a white line on the road) of the road being captured by a camera.  The width W of the road can be obtained from the white line data of the road being captured by the camera.

Title: Analog-to-digital converter
Inventor: FUJITA TSUNEO
IPC: H03M1/36
Filed: 1982-02-18
Abstract: PURPOSE:To obtain an A/D converter of a high speed, by converting an output  to a Gray code by a code converting circuit, and after that, latching it, subsequently, converting it to a binary code, and after that, latching it in opposite  phase. CONSTITUTION:Analog input voltage VS is compared with a reference value by comparators 30-37. A position detecting circuit 50 detects a boundary by which an output of the comparator is changed to ''0'' from ''1'', and sets a gate output corresponding to a position of the boundary, among gates 40-47, to ''1''. The first code converting circuit 151 converts an output of the detecting circuit 50 to a Grary code. This converted output is latched by the latching circuit 351 in the first place, and after that, is inputted to the second code converting circuit 251. The second converting circuit 251 converts the inputted Grary code to a binary code, and the second latching circuit 451 latches an output of the second converting circuit 251 in opposite phase to the first latching circuit 351. In this way, A/D conversion can be executed at a high speed.

CONSTITUTION:Hot air is injected to the internal surface of the end section of a resin hose (6) to heat said internal surface, and the end section of the hose (6) is pressed to weld the heated internal surface. Accordingly, since hot air is injected to the internal surface of the end section of the hose (6) and said end-section internal surface is heated and melted, the molten sludge of a resin does not adhere on a heated cone as seen in conventional devices thus inhibiting the generation of a noxious gas due to the combustion of the molten sludge, then maintaining clean work environment.

Title: On-load tap changer
Inventor: MURATA HISAO
IPC: H01F29/04
Filed: 1984-02-16
Abstract: PURPOSE:To prevent short-circuit between taps by connecting and inserting in series a parallel circuit of fuse and oil-immersed auxiliary contact between a vacuum valve for resistance contact of each pair and vacuum valve for main points. CONSTITUTION:In case cut-off performance of valves WA, WB for resistance contacts is deteriorated and long arc is generated, short-circuit between taps can be prevented by detecting gas and oil flow due to overheat and melting of current limiting resistors RA, RB. In case the cut-off performance of both valves HA, HB for main contacts and WA, WB for contact resistance are deteriorated and longer arc is generated, the oil-immersed auxiliary contacts KA, KB open while the power is being supplied when the exchange proceeds and the arc is generated in the oil. A current flows into the fuses FA, FB by such oil-immersed arc voltage. While the power is being supplied to the fuses FA, FB, exchange loss increases. When the valves HB, HA for main contact in the remote side open, short-circuit is generated between taps. But the fuses FA, FB melt due to a circuit, current flowing in such a case and the short-circuit condition is cancelled. Thereby, tap change of transformer can be realized without giving damage to the tap changer itself under the loading condition.
