Title: Parallel arithmetic processing unit
Inventor: SASAKI TORU
IPC: G06F9/38
Filed: 1990-10-31
Abstract: PURPOSE:To enable more efficient processing to execute by providing an execution control part which controls the execution of an arithmetic result corresponding to a branch state to a branch control part for instruction words. CONSTITUTION:The branch control part 32 for instruction words is equipped with the execution control part 6 which controls the execution of the arithmetic result of an arithmetic unit, which performs the arithmetic of a part other than the branch control part, corresponding to the branch state. Consequently, not only instructions which are executed when branching requirements are not met, but also instructions which are executed when the branching requirements are met can be arranged in instruction words OP1 - OP3 by the specification of the execution control part 6. Therefore, the ratio of the numbers of the instructions which are executed when a branching process is performed and the instructions which are executed when not can be set corresponding to the probability of the branching and the frequency of the setting of NOP(No Operation) codes decreases. Consequently, the performance of the parallel arithmetic processor is improved without increasing the hardware quantity.

Title: Wheel velocity sensor
Inventor: OGURA MASANORI
IPC: G01P3/481
Filed: 1997-10-24
Abstract: PROBLEM TO BE SOLVED: To provide a wheel velocity sensor which can detect a velocity of wheels close to zero and prevent deterioration of detection sensitivity. SOLUTION: A transmitter 7 is arranged at a surface of an axle 9 to rotate together with the axle 9. A receiver 8 is fixed in the vicinity of the axle 9 to receive waves from the transmitter 7. A change of a detection level because of the rotation of the axle 9 is thus detected. A revolution number of a wheel can be detected because the detection level changes as a result of the rotation of the axle 9. A size of the change of the detection level at this time is constant irrespective of the revolution number, thereby enabling detection of even the revolution number close to zero. Since no magnet is utilized, detection sensitivity is not deteriorated by iron powder, etc. The transmitter 7 is preferably driven by a battery and more compact in outer diameter than the axle 9.

Filed: 1986-12-09
Abstract: PURPOSE:To simplify the manufacturing process while improving the freedom of designing as well as the degree of integration by a method wherein impurity is doped in self alignment by means of monitoring a layer formed on a semiconductor substrate. CONSTITUTION:The peripheral part of an ion implanted layer 4 on a semiconductor substrate 2 is scan-irradiated with feeble focussing ion beams 11 by an ion gun 10; the secondary ion beams 13 are entered into a mass analytical instrument; and the distribution of impurity on the semiconductor substrate 2 is confirmed by the secondary distribution of curvature radius of the secondary ion beams 13 entered into the mass analytical instrument 12. Then, the overall ion implanted layer 4 can be mapped accurately and later the accelerating voltage is boosted to repeatedly scan-irradiate the specified position only with e.g., focussing ion beams 11 intensified. Through these procedures, another ion implanted layer 9 can be formed in the former ion implanted layer 4 in self alignment without using a mask at all thus entirely eliminating the mask formation process.

SOLUTION: This liquid crystal display device has the signal electrodes 25 having the first metallic layers 25a on an insulative substrate 1 side, the second metallic layers 25b formed thereon and the first insulator layers 16 consisting of the anodically oxidized films formed thereon. The second metallic layers 25b and the insulator layers 16 have apertures 20. The exposed parts 23 of the first metallic layers 25a in the apertures 20 and the first upper electrodes 17a of the thin-film diodes are connected. As a result, the contact resistance of the signal electrodes 25 and the first upper electrodes 17a of the thin-film diodes may be lowered and the electric resistance of the wiring parts may be lowered.  The lower oxide of ITO is hardly formed at the boundary between both in the connection of the signal electrodes 25 and the first upper electrodes 17a of the thin-film diodes and, therefore, adhesive power is increased.

Title: Hand-wound spiral spring structure for portable mechanical watch
Inventor: AOKI WATARU
IPC: G04B1/20
Filed: 1995-10-16
Abstract: PROBLEM TO BE SOLVED: To reduce the possibility of the application of excessive energy to a hand-wound spiral spring structure by clearly sensitively detecting the wound state of the spring and, at the same time, to prevent the breakage of parts. SOLUTION: When the user of a portable mechanical watch further rotates the stem of the watch while the spiral spring of the watch is wound, the outer peripheral section 30A of the spring which is pressed against the internal surface 12B of an incense box 12 by a spring attachment 38 starts to slide on the surface 12B. However, the sliding torque between the section 30A and surface 12B is set at a large value, the sliding of the section 30A is obstructed and the obstruction is transmitted to the rotation of the stem. Therefore, the user can sense the wound state of the spring. When the user rotates the stem with a stronger force, the rotational force becomes stronger than the sliding torque between the section 30A and surface 12B and the section 30A slides on the surface 12B in the direction shown by the arrow F2.  Therefore, the excessive energy is released and the breakage of parts can be prevented.
