Patent JP-2002056492-A (JP)
Title: Sensing device for vehicle and detecting device for number or axles
Inventor: HIGUCHI KAZUTO
IPC: G08G1/04
Filed: 2000-08-09
Abstract: PROBLEM TO BE SOLVED: To sense a vehicle, preventing a sensing failure, by using fewer light emitting devices and light receiving devices. SOLUTION: Each of a plurality of light emitting devices 1-1 to n arranged in the vertical direction and a plurality of light receiving devices 2-1 to n arranged in the vertical direction is opposed across a vehicle passage. Each light beam 15 emitted from each of the light emitting devices 1-1 to n is received by three light receiving devices in total of the light receiving device having the same height as that of the light emitting device and light receiving devices upper and lower than the light emitting device by one in the vertical direction. A driving part 5 time-dividedly lights and drives the light emitting devices 1-1 to n by a prescribed period so that light beam from two or more than light emitting devices may not simultaneously make incident on each of the light receiving devices 2-1 to n, under the control of a light emitting control part 6.  A vehicle sensing processing part 11 outputs a vehicle sensing signal since any light beam is interrupted based on a signal showing each lighting timing for the light emitting devices 1-1 to n and a detection signal from each of the light receiving devices 2-1 to n.

Title: Method for connecting printed wiring board
Inventor: TOTANI MAKOTO
IPC: H05K3/36
Filed: 2000-08-04
Abstract: PROBLEM TO BE SOLVED: To suppress solder bridges between adjacent wiring patterns and, at the same time, to make the inspections easier for defect solder junctions. SOLUTION: The land 2a of a Cu pattern 2 formed on a flexible printed wiring board 1 using a thermoplastic resin as an insulating substrate material and the land 4a of another Cu pattern 4 formed on a rigid printed wiring board 3 are electrically connected to each other through solder. At the time of connecting the lands 2a and 4a to each other, a prescribed gap is formed between the end face of the flexible wiring board 1 and that of a protective film 6 formed on the Cu pattern 4 of the rigid wiring board 3. Consequently, the solder bridges, etc., between the adjacent Cu patterns 2 and 4 can be prevented, because, even when excessive solder moves on the patterns 2 and 4 when a pressure is applied to the junction between the wiring boards 1 and 3 by means of a thermocompression bonding tool 9, the gap becomes the relieving space of the excessive solder.
