IPC: B29K105/12
Filed: 1989-12-12
Abstract: PURPOSE:To heat a block-shaped preform material uniformly in a short period of time and manufacture an FRP molded form having a high strength efficiently by a method wherein a dielectric loss improving agent is blended in the block- shaped preform material, in which reinforcing fibers are blended in plastic material, while high-frequency heating is applied, employing an electrode plate as a heating means. CONSTITUTION:Dielectric loss improving agent is added for the purpose of increasing the dielectric loss of a block-shaped preform material, in which glass fibers, carbon fibers or the like are blended into a plastic material as reinforcing fibers. The dielectric loss improving agent is a substance, whose own dielectric loss angle or dielectric loss factor is high, and therefore it shows a high dielectric loss factor while the same agent is constituted of silicon carbide, carbon black, various rubber materials and the like, for example. In this case, the blending amount of the dielectric loss improving agent is not specified especially. When the block-shaped preform material 1 is run on a belt 2 and a pair of high-frequency oscillators 3a, 3b is arranged so as to pinch the material 1 to project high-frequency, the temperature of the whole of block-shaped preform material may be risen uniformly within a short period of time.

Title: Computer
Inventor: OBA KUNIO
IPC: G06F12/16
Filed: 1988-12-21
Abstract: PURPOSE:To raise the reliability of a memory, and simultaneously, to shorten access time by writing previously the same data in plural addresses different from each other, and executing arithmetic processing only when read data more than a prescribed number are the same, and stopping the processing when the number of pieces of the same data does not fulfil the prescribed number. CONSTITUTION:A CPU 1 accesses the data in the memory 3 through a local bus 2. The CPU 1 writes one data previously at the time of initialization, for instance, in three different addresses of the memory 3 through the local bus 2. When those are read, each data is read out and compared, and if two or more data coincide with each other, the processing is continued. If not so, operation is stopped. Thus, since a parity bit generation/check circuit and a parity memory come to be useless, the simplification of a circuit and the shortening of the access time are advanced.

Title: On-board burn-in device
Inventor: GONDA TOMOHIKO
IPC: G01R31/26
Filed: 1996-12-05
Abstract: PROBLEM TO BE SOLVED: To obtain an on-board burn-in device that can apply a prescribed burn-in voltage with high accuracy, by inputting a voltage, in which a burn-in voltage and full-on voltage at an output transistor are added, to a voltage regulator circuit, and applying the prescribed burn-in voltage to an IC body. SOLUTION: In a normal operation, a switch 25 is connected to a GND, and an NPN bipolar transistor Q3 is turned off. As a result, an error in a voltage VCC at an IC body 3 is affected by an error in a resistance ratio R2 /R1 and in a voltage Vref2 on the basis of the relationship of VCC=(1+R2 /R1 ).Vref2 . In a burn-in operation, the switch 25 is changed over to the side of a voltage VB2 , and the transistor Q3 is turned on. As a result, a transistor Q1 is fully turned on without being affected by a collector current at a transistor Q2 . At this time, the voltage VCC at the IC body 3 in the burn-in operation is expressed as VCC = power - supply voltage VB1 - voltage VCE at the transistor Q1 . Consequently, the voltage VCE to which a burn-in voltage is added is input, as the power-supply voltage VB1 , to a Vign terminal 2, and the voltage VCC is used as the burn-in voltage.  Thereby, a prescribed burn-in voltage can be applied to the IC body 3.

Filed: 1988-12-23
Abstract: PURPOSE: To increase the supply quantity of toner by providing one carrying means with at least one aperture so that toner grains can be moved to a recording medium from the gap between a pair of carrying means. CONSTITUTION: The toner 34 is passed between a pair of charged toner conveyers 18 and 20 and the aperture 32 for passing the toner 34 carried between the conveyers 18 and 20 toward a printing head 14 is formed between the adjacent electrodes 24, 26 and 28 of one conveyer. Thus, the toner carried by the conveyers 18 and 20 and extracted from a toner cloud by a fringe electric field around the aperture can be increased. It is good that the electrode facing the aperture 32 is eliminated so that the toner 34 can be passed through the aperture 32 without obstructing the action of the conveyers 18 and 20 instead of such a case that the toner is passed between the adjacent electrodes 26, 26 and 28.

Title: Bump structure
Inventor: ASANO KOJI
IPC: H01L21/60
Filed: 1995-12-14
Abstract: PROBLEM TO BE SOLVED: To reduce the dispertion width thereby making feasible of the short time connection and the reduction in the occurrence of defective short circuit by decreasing the bump diameter on the connecting topmost stage on a substrate than that on the stage lower than the topmost stage. SOLUTION: Firstly, a bump 4 is formed on an electrode pad of a semiconductor device 1 in ball bonding mode. Later, another bump 3 in smaller diameter than that of the bump 4 is formed also in ball bonding mode. At this time, the laminated forming step of the bump 3 on the bump 4 brings about the effect of flattening the neck part of the bump 4 on the lower stage. Resultantly, the dispertion in the bump level as the whole bump depends only upon the bump level on the upper stage so that the dispertion width on the upper stage may be made narrower than that of the lower bump since the bump diameter of the upper bump 3 is smaller than that of the lower bump 4.
