Title: Sensor for measuring configuration
Inventor: SATO CHIKARA
IPC: G01B17/06
Filed: 1991-07-05
Abstract: PURPOSE:To grasp surface configuration of a specimen three-dimensionally by dividing a piezoelectric transducer of an ultrasonic probe into four parts, and providing patterns of combinations of transmission and reception between the vibrators from two directions X, Y. CONSTITUTION:A piezoelectric transducer of a configuration measuring sensor 1 is divided into four parts A, A', B, B' and a sensor 1 is installe on e.g. a specimen 4 having a slope in the X direction and ultrasonic waves are transmitted from the transducer A and the reflected waves from the (a) point are received at the A' point. Also, ultrasonic waves are transmitted from a piezoelectric transducer B and the reflected waves from the (b) point are received at the B' point. The intensity of the waves received at the A' point is compared with that of the waves received at the B' point so as to calculate the direction and gradient of the slope of the surface 5 of the specimen 4. When the gradient of the surface 5 extends in the Y direction this is the same as when the gradient of the surface 5 extending in the X diection is rotated by 90 degrees and in that case ultrasonic waves are transmitted from the transducers A' and A and received at the transducers B' and B, respectively. The waves are synthesized with each other whereby the surface configuration of the specimen 4 can be grasped three-dimensionally.

Title: Manufacture of aluminum foil base metal
Inventor: DOKOU TAKENOBU
IPC: B21B1/40
Filed: 1987-07-03
Abstract: PURPOSE:To eliminate structure difference in the longitudinal direction and to prevent variance in rolling characteristics by limiting a temp. of a rolled sheet and a holding time at the temp. after exceeding a specific drafting amount in course of hot rough rolling after soaking treatment of an A-Fe-Si-Cu alloy ingot having a specific structure. CONSTITUTION:An aluminum alloy ingot consisting of, by wt., 0.1-1.0% Fe, <=0.3% Si, <=1.0% Cu, and the balance Al is subjected to soaking treatment; then a temp. of the ingot is held at a temp. between 300-450 deg.C for >=1min. between a rolling pass after the total drafting amount exceeds 50% and the succeeding pass in course of hot rough rolling. The reason for limiting a temp. of a rolled stock and a holding time is such that holding treatment is performed after the total drafting amount exceeds 50%, stresses remain to facilitate deposition by the treatment, edge cracks of a sheet are generated at a temp. of <300 deg.C, and no effect is achieved at a temp. of >450 deg.C. If a holding temp. is held for >=1min., Fe and Si are deposited through the total sheet surface and the characteristics in the longitudinal direction are uniformized.

After this, an Al-Si alloy layer is deposited for interconnection for the second insulation layer 18. This procedure allows conductive surfaces to be exposed on the contact holes for the second insulation layer to both the first insulation layer and the substrate by successful reproducibility.

Filed: 1996-06-26
Abstract: PROBLEM TO BE SOLVED: To reserve a communication channel for maintenance for all electronic exchanges which cannot make communication with a maintenance terminal equipment directly or via a LAN on the occurrence of a fault in the LAN. SOLUTION: On the occurrence of a fault in the LAN, upon the reception of a maintenance from a maintenance terminal equipment 7 to an electronic exchange 2, an electronic exchange 4 discriminates it that communication to the electronic exchange 2 cannot be made via a LAN 10, and the maintenance command is transferred to the electronic exchange 2 through an RS232C interface and a speech charge management device 6. The electronic exchange 2 makes processing to the transferred maintenance command and returns the processing result to the electronic exchange 4 via the RS232C interface and the speech charge management device 6. The electronic exchange 4 sends the returned processing result to the maintenance terminal equipment 7 through a MODEM 8 and a data channel 9.  Thus, remote maintenance from a remote location to the electronic exchanance 2 disabled with LAN communication is executed by the maintenance terminal equipment 7.

Abstract: PURPOSE:To prevent the electric erosion due to working chips on the surface of a workpiece by removing the working chips from the upper surface of the workpiece by jetting fluid on the surface, in a wire-cut electric discharge machine for carrying out the electric discharge machining in an insulative working liquid. CONSTITUTION:When electric discharge work is carried out by applying the pulse voltage between and a wire electrode and a workpiece 2 in an insulative working liquid in a working tank 1, the generated working chips are discharged from the gap between the wire electrode and the workpiece 2, by the working liquid jetted from an upper part working liquid jetting nozzle 4 and a lower part working liquid jetting nozzle 5. The discharged working chips tend to be piled on the upper surface of the workpiece 2 which is separated from a working part and on which the flow of the working liquid is relatively gentle. However, the working liquid is always jutted on the whole of the upper surface of the workpiece 2 from a working liquid injection nozzle 13, and the piling of the working chips on the upper surface of the workpiece 2 is prevented. Accordingly, the workpiece 2 is prevented from being electrically eroded by the working chips.
