Filed: 1996-04-25
Abstract: PROBLEM TO BE SOLVED: To reduce the write time and manhours required when data to a redundant cell are substituted by changing over only metallic wirings in a mask ROW having a redundant function. SOLUTION: When there is a defective bit by a selection test, the defective bit is detected at a processing step S3, a minimum substitutional unit, in which there is the defective bit, is indexed at a processing step S4, and the number of the cells of on-bit and off-bit in the minimum substitutional unit is compared at a processing step S5. The cells in a smaller number are selected and used as write data to a redundant cell at that time, but the consistency of the write data and an expected value is decided at a processing step S7, and a test flow, in which an output variable circuit is operated, is employed at the time of discordance, thus reducing the write time and manhours and improving production efficiency.

Filed: 1979-08-21
Abstract: PURPOSE:To prevent contact between wires when wiring is performed using long wires by a method wherein bonding wires, which connect between bonding terminals, are aligned using V-grooved arraies. CONSTITUTION:When a connection between an LED array 1 and a driving circuit element 2 is performed using a wire bonding, a pitch P of a wire 4 is smaller than the diameter L of pads 3a and 3b for the purpose of performing a high density wiring. Also, pads 3a and 3b are so arranged that they will no overlap each other by changing the length of the wire 4 successively. And, a V-groove is provided with a groove pitch equal to a pitch P of the array, and as the array 8 has a heavier thickness than that of the crystal of the array 1 and the array 2, the wire 4 can be fixed easily in the V-groove. As a result, contact between wires can be prevented even when long wires are used and the high density wiring can be performed.

Title: Servo circuit
Inventor: SUZUKI AKIHIRO
IPC: G05D3/12
Filed: 1994-04-20
Abstract: PURPOSE:To eliminate unnatural motion caused by a backlash of a gear of a driving system and perform accurate driving exactly as driving systems are operated when they are operated at the same time. CONSTITUTION:For the servo circuit which performs speed control over a motor, a time t1 for driving by the backlash generated by a gear of, for example, a pan, tilt, zoom, or focus driving system is set and at the time of reverse driving, the motor is driven with a small speed control voltage in the backlash driving time t1. For a joy stick, a backlash operation area is provided, and speed control for the backlash is performed in the operation time of the operation area. Consequently, the rotational frequency of the motor is prevented from increasing before substantial driving. Further, when plural driving systems are controlled at the same time, the respective driving systems are equalized in substantial driving start time after the driving by the backlash.

Title: Valve gate device for injection molding die
Inventor: HOSONO NOBUYOSHI
IPC: B29C45/28
Filed: 1991-05-10
Abstract: PURPOSE:To eliminate the generation of flash in a gate trace of a molded product. CONSTITUTION:A gate 23 is formed in the tapered shape getting thinner toward a cavity 13. The end of a valve 26 is protruded from the gate 23 into the cavity 13 when the gate 23 is blocked. The length (c) in the axial direction of a contact section of the peripheral face of the gate 23 with the valve 26 is made as close as possible to zero (0). As the gate 23 is of tapered shape, resin in the peripheral sections in said gate 23 is returned as shown by the arrow mark when the gate 23 is getting closer. As the length (c) in the axial direction of the contact section is very small, the resin is almost not pushed out to the side of the cavity 13 from between the peripheral surface of the gate 23 and the valve 26. The generation of flash can be prevented by said arrangement. Nevertheless, the gate 23 can be closed securely by making the valve 26 protruded into the cavity 13.

Abstract: PURPOSE:To oscillate a first active layer of a semiconductor laser in a lateral basic mode and to obtain an output of a lateral basic mode from a second active layer by resonating an optical wave only in the first layer, and merely conducting optical amplification due to an induction discharge in the second layer. CONSTITUTION:An epitaxial layer 46 on a substrate 44 is formed of upper and lower buried layers 38, 50, an intermediate current blocking layer 48, and active layers 34, 36, and the layer 48 is formed between the active layers 34 and 36. Electrodes 40, 42 are formed in the shapes and disposed at positions to inject currents to the layers 34, 36, and an electrode 52 is attached to the substrate 44. An optical wave discharged by the current injection is reciprocated in the layer 34 to resonate the optical wave. The wave is partly guided to the layer 36, inductively discharged in the layer 36, and the optical wave coincident in the phase and the wavelength to those of the optical wave reciprocated and guided in the layer 34 is discharged. An optical amplification due to the inductive discharge is merely conducted in the layer 36, and the optical amplification is increased together with the injection current amount. Accordingly, when the layer 34 is oscillated in a lateral basic mode, the optical wave of high output is obtained in the basic mode from the layer 36.

Abstract: PURPOSE: To attain high-reliability comparative decision operation by allowing CPU in a R/C mode between a couple of CPUs to make a comparison.  
     CONSTITUTION: Different microprograms are loaded into CPUs 101A and 101B, which operate in different CPU modes.

Next, CPU 101B in a R/C mode can only read data from main memory 102 and CM 105A. Although CPUs 101A and 101B execute exactly the same program, CPU 101A in the R/W mode is given priority without fail. This is realized by starting the service by memory common-bus 103 from the side of CPU 101A in the R/W mode.
