Patent JP-S61104632-A (JP)
Title: Semiconductor device
Inventor: SAKAUCHI HIDEO
IPC: H01L21/60
Filed: 1984-10-29
Abstract: PURPOSE:To enable automatic wire bonding of high accuracy by a method wherein an electrode lead-out pad is shaped in slit or spiral form, so that irradiating light is irregularly reflected at the pad part, and that always a fixed amount of reflected light comes into a condenser. CONSTITUTION:Since an electrode pad 9 is shaped in slit 11, 12 or spiral 13, 14 form, incident light from an illuminating source 6 is irregularly reflected on its surface, and so reflected light always at a fixed level strength is converged by the condenser 7 regardless of the angle of the optical axis X-X' of the incident light and the condenser system. Accordingly, the position of the electrode pad 9 is accurately detected and recognized. Therefore, automatic wire bonding of extremely high accuracy is enabled without the need of either special assemblers or precise adjustments during assembly. In the case of using aluminum or its alloy as the electrode-forming material, it is laminated by sputtering or evaporation on the semiconductor substrate where emitter and base regions have already been formed; then, electrical contacts with the semiconductor layer and electrode lead-out pads are formed by photoetching.

Title: Vertical magnetic recording head
Inventor: NISHIMURA NOBUO
IPC: G11B5/187
Filed: 1984-10-30
Abstract: PURPOSE:To attain simple constitution not requiring a tunnel erase head by setting a track width at recording to a track width smaller by a prescribed width than that at reproduction. CONSTITUTION:Suppose that a track remained unerased (data area B) caused by a track position error exists at a side of a reproducing track (data area A) having a track width T over a width d1. In running a main magnetic pole in the state above, its reproduced area is an area shown in a middle part 21b having a length of d3 and a thickness of delta2 resulting from the subtraction of a part having a length of d2 and a thickness of delta1 from both ends of the track width T of the main magnetic pole. Thus, the recording track width T and the reproduced track width d3 are set differently, and a vertical recording head not requiring any tunnel erase head is realized by making the difference to a nearly similar value as the track position error.

Title: Safety device for automatic transmission
Inventor: HIRAMATSU TAKEO
IPC: F16H61/16
Filed: 1988-09-14
Abstract: PURPOSE:To disable achievement of reverse stage even if an operating state switching valve is switched to reverse position during drive operation by providing an oil path switching mechanism for discharging hydraulic pressure to be fed to a reverse friction element when the engine rotation is higher than a predetermined level and the operating state switching valve is switched to first position. CONSTITUTION:Upon erroneous switching of an operating state switching valve 1 to reverse position when the vehicle speed exceeds over a predetermined level, hydraulic pressure P1 flows between the lands 8, 9 in the switching valve 1 into oil paths 2, 3. A vehicle speed sensor 20 detects vehicle speed exceeding over a predetermined level, then a controller 18 controls a solenoid valve 17 based on an output from the sensor 20 to release pressure oil from an oil path 16 so as to slide a spool valve 11 to the left and bring to a hydraulic pressure discharging position. Consequently, pressure oil fed through the oil path 3 between lands 12, 13 of an oil path switching valve 10 is discharged through an oil discharge path 16 and not fed to a low reverse brake 5. Since reverse stage is not achieved even upon switching of the switching valve 1 to reverse position, abrupt braking or engine stall does not occur.
