Title: Wafer substrate of semiconductor integrated circuit
Inventor: MUNAKATA KOUNIN
IPC: H01L21/66
Filed: 1983-01-25
Abstract: PURPOSE:To enable two or four semiconductor integrated circuits to be tested simultaneously reducing the testing time by a method wherein several chips of the same pattern formed on a wafer are arranged so that the sides not yet formed of pad may come into contact with each other every two or four chips. CONSTITUTION:Bonding pads are formed on three sides and the directions of chips are reversed every other row. Resultantly the chips are arranged so that the sides not yet formed of pad of the two adjoining chips c1, c2 may come into contact with each other. At every assembly of two chips (c) on a semiconductor IC wafer substrate, pointers (a) for electric connection are mechanically connected with each other to perform electrical tests of the two chips simultaneously. Any defect such as dispersion of the length of pointers (a) may be corrected remarkably enabling two chips (c) to be tested easily although the sides being able to form the pads (b) are limited to the three sides of chips (c).

Inventor: MAKABE HIDEKAZU
IPC: G01N3/32
Filed: 1985-01-25
Abstract: PURPOSE:To measure the top end position of the crack of a fatigue test piece by microscopes with high accuracy without contact by detecting the reference position and the top end position of the crack from the luminance level and binary coded signal of an image signal which picks up the image of the fatigue test piece and calculating the distance between both positions. CONSTITUTION:The microscopies 20, 21 are disposed to face the surfaces on both sides of the fatigue test piece 10 on which a reference line for measuring the position of the crack are drawn. The image signal of the test piece magnified through the microscopes 20, 21 is fed to a means 32 for detecting the reference line and a means 33 for detecting the position of the top end of the crack. The means 32 integrates the luminance level of the image signal in the same direction as the direction of the reference line and detects the reference line position from the max. luminance level position. The means 33 codes the image signal to a binary value and detects the top end position of the crack from the discrimination on the continuity of a high level value. The distance between the reference line and the top end position of the crack is detected from the detected values of the means 32, 33 in a distance detecting part 40.

IPC: C02F1/44
Filed: 1998-01-26
Abstract: PROBLEM TO BE SOLVED: To provide a method capable efficiently dehydrating a sludge with a pressure dehydrator eliminating the need of a large-sized dehydrating machine or a membrane concentrating device.

Filed: 1981-01-29
Abstract: PURPOSE:To obtain the quantity of deposition of sand or the like and the deposition distribution, by providing many ultrasonic sensors at different fitting angles to radiate ultrasonic waves from a constant point on a waterway toward measure points on the waterway bottom. CONSTITUTION:A sensor fitting table 3 is provided at a constant point of a waterway 1 of a pond with sand or the like deposited, and many ultrasonic sensors 4a, 4b, 4c-4n are provided on this table 3. Sensors have fitting angles and directions different from one another to direct ultrasonic waves toward plural measuring points which are predetermined on the waterway bottom. For example, when the length from the sensor 4b to a measuring point, the length from the sensor to the surface of deposition, and the height of deposition of sand or the like are denoted as (l), l1, and l2 respectively, l2=l-l1 is true. Since a radiation angle (alpha) of ultrasonic waves of each sensor is set prliminarily, a height H of deposition of sand or the like in the vertical direction is obtained on a basis of equation H=l2Xcosalpha by an operating circuit. This height is operated to display quantities of deposition and the deposition distribution.

Title: Detection of accident section in overhead transmission line
Inventor: HASHIMOTO MAKOTO
IPC: G01R31/08
Filed: 1993-01-29
Abstract: PURPOSE:To heighten detecting accuracy in a method to locate an accident section in an overhead transmission line by using an accident electric current flowing to an electric power line. CONSTITUTION:Electric currents of the first and the second lines 4 and 5 are detected by using space magnetic field sensors 1 and 2. An electric current of an overhead earth-wire 6 is also detected by an electric current sensor 8. Since an overhead earth-wire electric current component being a cause of erroneous detection is contained in output signals of the sensors 1 and 2, the overhead earth-wire electric current component is found by using a signal of the sensor 8, and this quantity is removed from the signals of the sensors 1 and 2. Thereby, since only an electric power line electric current component remains, a change equivalent to the electric current component is extracted as an accident electric current, and an accident section is specified by location by a phase difference or the like. Thereby, detecting accuracy is heightened.

Filed: 1999-01-22
Abstract: PROBLEM TO BE SOLVED: To obtain a management system for trace information which facilitates maintenance operation and does not lose all trace information even if a fault occurs to a trace table by imparting the name of a function causing generation of the trace table and recording the contents of operations by the function. SOLUTION: Operation programs F1 to F3 calls a trace information acquiring program C1 at a proper time. The trace information acquiring program C1 when called obtains the execution processes of operations of the operation programs F1 to F3. Each time the trace information is obtained, trace tables T1 to T3 are newly generated on a disk drive M3 and the obtained execution processes (trace information) are registered in the trace tables T1 to T3. Thus, the trace tables T1 to T3 are generated by operations by operation functions, so even if a fault occurs to one table, trace information which is lost is limited to one operation.
