Title: Rear wheel steering device for vehicle
Inventor: OMURA HIROSHI
IPC: B62D113/00
Filed: 1989-11-22
Abstract: PURPOSE:To safely return rear wheels to the neutral position as far as no problem occurs by operating a motor to return rear wheels to the neutral position if at least two outputs of three detectors practically coincide when a rear wheel steering position detecting means fails. CONSTITUTION:A control unit 38 judges whether rear wheel steering angle sensors 120 or a rotary encoder 120a fails or not, if a failure occurs on rear wheel steering angle detectors, it judges whether all signals of three detectors are noncoincident or not. If all signals are noncoincident, clutches 49 and 50 are cut off, and rear wheels are returned to the neutral position by the action of a center ring spring means 36. If all signals are not noncoincident, the steering position of rear wheels is recognized by signals of two proprly-operating rear wheel steering angle detectors. A servo motor 32 is operated to return rear wheels to the neutral position.

Title: Handy type bar code scanner
Inventor: ICHIHARA NAMIKO
IPC: G06K7/00
Filed: 1989-11-22
Abstract: PURPOSE:To always grasp whether reading is correctly executed or not by providing first and second optical read parts, processing part to collate binary signals to be respectively outputted from these read parts, and output part to output one of collated results at least. CONSTITUTION:When an arbitrary bar code is read, first and second optical read parts 1a and 1b read reflected light from the same bar code at slightly different timing, convert the light to electric signals corresponding to respective levels, convert the signals to the binary signals of a serial form by comparison with a threshold value and transfers the signals to a processing part 2. The processing part 2 collates the binary signals of the serial form sent from the first and second optical read parts 1a and 1b while compensating the deviation of the timing each other. When the collated results are dissident, the read binary signals are not sent to a host device but an output part 5 displays the generation of erroneous reading or generates a signal tone. Thus, erroneous reading is prevented.
