Title: Multiprocessor system
Inventor: MAEDA KOJI
IPC: G06F12/00
Filed: 1988-12-15
Abstract: PURPOSE:To decrease the overall power consumption of a multiprocessor system by using each processor having the working and stand-by modes and keeping these processors in the stand-by mode except a specific processor. CONSTITUTION:A multiprocessor system includes two processors 2 and 3, a common memory 4 used in common by both processors 2 and 3, and a timing generating circuit 1 which controls the states of both processors. The memory 4 is connected in parallel to the processors 2 and 3 via a bus signal line 5. Each processor has a working mode and a stand-by mode having the smaller power consumption than the working mode. Then all processors are kept in the stand-by mode except a specific processor and at the same time the bus 5 is released. Thus the accessable state is repetitively secured for only the specific processor to the memory 4 while the specific processor is successively changed. As a result, the overall power consumption is decreased for a multiprocessor system.

Title: Semiconductor memory
Inventor: MATSUNO KATSUMI
IPC: H01L21/8246
Filed: 1993-12-17
Abstract: PURPOSE:To obtain a low noise, low power consumption, high integration non- volatile semiconductor memory which can retain information stably by employing a ferroelectric. CONSTITUTION:When the operation is ended, a selection transistor is turned OFF after equalizing the potentials, of data line and a plate electrode. At the time of waiting, potential at an information accumulating node is sustained close to the plate potential through the leak of the selection transistor and a ferroelectric capacitor. At the time of reading, data line isolation switches CSWa1,... are interrupted upon finish of amplification through sense amplifiers SAa1,... and a memory cell array is returned to waiting state. Consequently, information can be retained stably with low power consumption even if the plate potential is constant. Since the leak characteristic request of the selection transistor and ferroelectric film is not strict, memories can be fabricated easily with high yield. Furthermore, a memory requiring no formation of well can be obtained by employing a thin film transistor as the selection transistor.

Title: Reverse conducting gate turn on thyristor and its manufacture
Inventor: NIINOBU HIROHARU
IPC: H01L29/74
Filed: 1991-12-02
Abstract: PURPOSE:To reduce the power loss in a diode structure part without damaging the electric property at the electric structure part by thickening the second region existing in a diode area more than the first region existing in a thyristor area. CONSTITUTION:Since an n-type high concentration layer 11 exists between an n-type high concentration layer 4 and an r-type base layer 1 in a diode part Y, the thickness D1a of the center part 1a of the n-type base layer 1 in the diode part Y is thinner than the thickness D0 of the peripheral part 1b existing in a GTO part X. Accordingly, to thicken the peripheral part 1 of the n-type base layer 1 in the GTO part X, the increase of the residual carriers inside the center part 1a of the n-type babe layer 1 in the diode part Y can be suppressed. Therefore, the power loss at the diode structure part can be reduced without damaging the electric property at the thyristor structure part.

Title: Ink jet recording head
Inventor: FUKAZAWA NAOTO
IPC: B41J2/055
Filed: 1992-11-02
Abstract: PURPOSE:To increase the speed of ink discharging and reduce the size of a head. CONSTITUTION:An ink supply passage 6 is formed between an ink reservoir 7 and an ink pressurizing chamber 5. The passage 6 is formed of a groove formed on a board and of a sawtooth state in combination with straight lines perpendicular to an ink flowing direction and narrowed in a flowing direction. Further, shapes of grooves of both sides are formed symmetrically, thereby forming a fluid diode in an entire groove. That is, a resistance when ink flows is reduced in a forward direction of the ink flow with an arrow B, and a resistance when the ink flows reversely to an arrow W is oppositely increased. Thus, suction and discharge of the ink due to the chamber 5 are efficiently conducted.

Filed: 1990-11-22
Abstract: PURPOSE:To realize highly accurate airtightness inspection by casting scattered light on the surface of water so as to illuminate the surface, refracting and absorbing the scattered light at the recess parts of bubbles, forming a black level region, and detecting the bubbles. CONSTITUTION:One image frame is inputted from a TV camera. A black level region having a specified size (an image has a part protruding from the inside of a circle having a diameter d1 and contained into a circle having a diameter d2. d1 < d2) is extracted by image processing. Whether the outer periphery of the black level region has an arc shape or not is detected. Thereafter, whether the independent black level region having the above described size is detected or not is checked. When the region is detected, the defective airtightness is judged. When the region is not detected, the independent black points are extracted and counted. The independent black points in this case are the minute independent black level regions contained in a circle having the specified diameter d3 (d3 < d1) or less. When the independent black points are counted by the specified number as a threshold value, the defective airtightness is judged because the minute bubbles in the fog state is detected.

Title: Bumper mounting structure
Inventor: KUDO FUMIO
IPC: B60R19/24
Filed: 1989-12-08
Abstract: PURPOSE:To make it possible to avoid collision between the upper part of a bumper reinforce and a headlamp by mounting a side stay on the bumper reinforce, with the lower end of its point end edge positioned outside a car width direction from the upper end of the point end edge. CONSTITUTION:In the case of collision taking place from a diagonal direction outside a car width direction at the time of running, a distance between an upper end 23h and a point E is larger than a distance between a lower end 23g and a point G by the amount of a distance (d). Consequently, moment with the upper end 23h serving as a supporting point by impact force F, applied to the point E, becomes larger that moment with the lower end 23g serving as a supporting point by impact force F applied to the point G. Accordingly, a reinforce 2 is moved to the rear of a vehicle from a position, shown by a dotted line, by the impact force F at the time of collision so as to absorb the impact force F. The longitudinal wall part 2a and the upper surface part 2b of a collision part of the reinforce 2 are faced downward as shown by a solid line, and a lamp 4 is prevented from generation of damage by collision at both side parts in the car width direction of a bumper even in an automobile in which the headlamp 4 is arranged just above the reinforce 2.
