IPC: G06F15/16
Filed: 1992-05-26
Abstract: PURPOSE:To make the parallel conversion operation of a loop sentence efficient by converting a subscript in the loop sentence by describing a descriptor to the loop sentence. CONSTITUTION:It is decided whether data operated by the loop sentence (FOR sentence) is distributed previously all together or finely-separately to each cell of a parallel computer as a data distribution type 1. Besides, the subscripts 3a to 3d indicating loop operation alloted to the each cell are generated in accordance with the separation type of the loop sentence and the separation type 1 of data. The loop sentence to be parallel-processed is selected from a source program and the descriptors 2a to 2d indicating the separation type are added before the loop sentence in accordance with the distribution type of data. At the time of converting the source program including the loop sentence added with the descriptors 2a to 2d into an intermediate program, the prepared subscripts 3a to 3d are selected in accordance with the descriptors 2a to 2d to convert the loop sentence into that having subscripts (p, q) corresponding to parallel processing.

Title: Manufacture of semiconductor device
Inventor: YABUSHITA TETSUO
IPC: H01L21/60
Filed: 1990-05-23
Abstract: PURPOSE:To reduce the pitch between pads and to reduce the size of a semiconductor chip by a method wherein the shape of balls bonded to the pads is formed into an elliptical shape extended in the directions perpendicular to the sides of a semiconductor element, which is provided with electrodes arranged on all sides. CONSTITUTION:The shape of a pressure bonding ball 2 bonded to a pad 1 is formed into an elliptical shape extended in the direction perpendicular to a side 4 of an IC 3. This is effective to make the diameter of the ball small, which is formed when the ball 2 is pressed and bonded to the pad, but when the diameter is made too small, a reduction in a strength of pressure bonding is generated. Therefore, the strength of pressure bonding can be held by forming the shape of the ball 2 into the elliptical shape extended in the direction perpendicular to the side 4. Thereby, in a plastic package, which is needed the arrangement of a multitude of pads and is provided with a multipin, the pitch between the pads can be made small and a reduction in the size of a semiconductor chip becomes possible.

Title: Semiconductor device
Inventor: MOGI JIYUNICHI
IPC: H01L27/04
Filed: 1978-10-30
Abstract: PURPOSE:To prevent adverse effects by a small number of carriers to other circuit portions on a semiconductor substrate, by inhibiting the injection of few carriers to the substrate by forming a region with high concentration to a junction region with the substrate of a substrate bias generating circuit. CONSTITUTION:A coefficient of injection of a small number of carriers is decreased by changing a semiconductor substrate portion 8 just nuder a region 4, in which junction with a substrate 1 of a substrate bias generating circuit is brought to a forward potential condition, into a P-type region with high concentration, the injection of few carriers to the semiconductor substrate 1 in the case when junction between the region 4 and the semiconductor substrate 1 is put to the forward potential condition is suppressed and the inflow of a small number of carriers to a memory element dynamically operating and a joint of high impedance is prevented. Regions 9, 10 in a conduction type opposite to the semiconductor substrate 1 are made up around transistors Q1, Q2 for the substrate bias generating circuit, and few carriers diffused into the semiconductor substrate 1 are absorbed by applying proper bias voltage to the regions 9, 10.

Title: System for thinning line of diagram
Inventor: TANAKA NAOYA
IPC: G06V10/34
Filed: 1989-05-25
Abstract: PURPOSE:To generate a line-thinned diagram free from distortion in a point adjacent area where a circular graphic component is in contact with another figure by separating the circular graphic component from a diagram picture and re-synthesizing them after line-thinning each of the circular graphic component and other components separately. CONSTITUTION:A circular graphic component separating part 17 cuts off the picture existing within the distance of the sum of a radius and the length of line width from the central coordinate in respect of a circular isolated white picture element area. Since the picture obtained by cutting off the area B from the figure A generates the distortion such as the break or the thinning of a line at the point adjacent area, the distortion is corrected by a graphic correcting part 18, and then, the figure C is obtained. Then, the circular graphic component and the diagram are line-thinned separately by line-thinning processing parts 2 and 3. A position correcting part 41 corrects a position into the position of contact. A graphic synthesizing processing means 4 re-synthesizes these two kinds of the figures. Then, a graphic synthesizing part 42 executes re-synthesis while comparing the figure with an original graphic picture so that the circular figure preserves the topological property of the original graphic picture.

Title: Electromagnetic tripping device for circuit breaker
Inventor: HIRAKI SHUNKAI
IPC: H01H71/74
Filed: 1988-05-31
Abstract: PURPOSE:To prevent mistripping due to rush current by energizing a plunger, which is driven by the coil current toward the yoke, in the opposite direction to plunger driving with a pressure spring, and by pressing in the plunger driving direction by a spring through a lever which is to drive a contact opening mechanism. CONSTITUTION:When the force of a pressure spring 9 is set greater than the force of a spring 11 of a stopper 13, a plunger 8 heaves one end 10a of a lever 10. When a current over a set value flows through a coil 2, an attraction force is applied to drive the plunger 8 downward. If at this time the current flowing through the coil 2 increases, the attraction force increases also, and the speed at which the plunger 8 is driven downward becomes greater. However great the plunger 8 attracting speed becomes, the revolving speed of the lever 10 round a shaft 12 remains a speed determined by the inertia moment of the lever 10 and the pressing force of the spring 11. When the lever 10 rotational angle exceeds a certain value, one end 10b actuates the contact opening mechanism of the circuit breaker.

Filed: 1989-05-26
Abstract: PURPOSE:To prevent an incongruous noise when performing on-hook from being sent by squeezing a transmission sound volume with a sound volume adjusting circuit just before performing the on-hook by detecting the on-hook operation of a handset with a sensor. CONSTITUTION:When the handset 2 is brought close to a telephone set main body 1 to perform the on-hook after ring-off, the sensors 22 and 12 are operated, then, the approach of the handset 2 is informed to the sound volume adjusting circuit (AMP) 11. The AMP 11 increases an attenuation quantity according to the approach of the sensor 22 to the sensor 12, and the attenuation quantity goes to infinity just before performing the on-hook. Thereby, it is possible to prevent the incongruous noise from being heard from a transmitter 21 when the onhook of the handset 2 is performed, and also, to prevent the noise from being sent to a speech line.

Title: Fixed optical member for rod lens
Inventor: FUKUDA KAZUYUKI
IPC: G02B7/02
Filed: 1990-05-25
Abstract: PURPOSE:To fix a rod lens and a holder easily, securely, and stably for a long period by pressing one end surface of a joining member with a die which is thinner than the joining member and joining the rod lens and holder together, and then heating them for mutual diffusion. CONSTITUTION:One end surface of the joining member 2 is pressed with the die 4 which is thinner than the joining member 2 to charge the joining member 2 in the gap part between the rod lens 1 and holder 3, which are treated thermally to cause the mutual diffusion between a surface processing member 13 and the joining member 2, thereby joining and fixing them. Therefore, the applied pressure is reduced by the deformation of the ring-shaped joining member 2 and surface processing material 3, so the rod lens 1 does not break and even if there is an uncharged part in the gap part between the rod lens 1 and holder 3, the adhesive strength is increased by the mutual diffusion between by the surface processing member 13 and joining member 2 by the heat treatment. Consequently, the rod lens can be fixed easily, securely, and stably for a long period.
