Title: Overhead-line deterioration inspection apparatus
IPC: H02G1/02
Filed: 1992-04-03
Abstract: PURPOSE:To install an apparatus easily and to perform an inspection stably by providing an AE sensor which faces a clamped overhead line wherein an acousting emission from an overhead line which has been vibrated is detected and the deterioration of the overhead line is inspected. CONSTITUTION:An acoustic emission which is generated from a defect part is superposed on vibrations; it is propagated in an overhead line 6; it reaches a position where a discharge clamp 2 as an overhead-line deterioration inspection apparatus 1 is attached. Here, the vibrations which are propagated in the overhead line 6 are propagated in a trunk part 8 at an upper-part clamp piece 4 from the bottom face 9 of the trunk part 8 at the clamp piece 4 which has been brought into close contact with the outer circumferential face of the overhead line 6; they reach the passage bottom part 17; in addition, they reach a sensor 19. The sensor 19 faces the overhead line 6 via the passage bottom part 17 at the clamp piece 4 and via silicone grease 18; it is provided with a prescribed acoustic transmission characteristic with reference to the overhead line 6. As a result, an inspection signal due to the vibrations is transmitted linearly to the sensor 19. Consequently, when the output signal of the sensor 19 is analyzed, whether the defect part exists or not and its position are detected.

IPC: G06F3/048
Filed: 1983-05-13
Abstract: PURPOSE:To recognize at a glance the data with which the present value is not displayed correctly by changing the data part obtained from a faulty device to a specific display color among the data on a display screen. CONSTITUTION:An electronic computer 4 feeds the extent state of process quantity from digital controllers 2a-2n via data transmitters 3a-3n and stores data in a table 5. A transmission monitor part 7 monitors the fault of transmitters 3a-3n by monitoring disconnection, the increase of noise, etc. Then the computer 4 shows a faulty transmitter to a display output control part 6 when the corresponding fault is detected. Thus the part 6 discontinues to extract the data on the faulty transmitter out of the table 5 and changes the screen color of a display device 8 at the area where the corresponding data is displayed. At the same time, a transmission monitor part 7 delivers the fault also to a fault alarm window 9 and lights up the corresponding window to inform the generation of the fault.

IPC: E03C1/122
Filed: 1996-04-04
Abstract: PROBLEM TO BE SOLVED: To quickly defarm bubbles generated in a drain horizontal pipe by forming a nozzle ejecting a liquid towards the downstream side on the upper side in the drain horizontal pipe. SOLUTION: A pressure detector 8 detects in-pipe pressure on the upstream side of a drain horizontal main pipe 4, and transmits a detected signal to an automatic controller 9. The automatic controller 9 operates a liquid delivery device 7 when the in-pipe pressure detected by the pressure detector 8 reaches a preset abnormal step-up level.

Title: Automatic profiling method for weld line
Inventor: IDE EIZO
IPC: B23K9/12
Filed: 1985-04-19
Abstract: PURPOSE:To increase the welding accuracy by operating the sum of the arc length and wire extension from the welding current, welding voltage and wire feeding speed and by controlling the welding torch based on the pattern of this variation in the distance between the tip and the body to be welded. CONSTITUTION:A current detector 35 detects the welding current and amplifier 32 finds the feeding speed of a wire 9 via the signal transmitted from the rotation detector 34 of a rotary encoder, etc. and inputs into a control device 25. The welding voltage V is inputted to the control device 25 from voltage detector 6. The control device 25 finds the sum of the arc length and wire extension from the welding current, welding voltage and wire feeding speed and controls a welding torch 17 via convertor 26 based on the variation pattern of this information value. The welding accuracy and operability are increased due to the torch 17 being enabled to be controlled automatically from the welding conditions directly.

Title: Microwave oven
Inventor: IWABUCHI YASUSHI
IPC: H05B6/78
Filed: 1988-04-04
Abstract: PURPOSE:To make microwave electric power which enters the inlet of a choke cavity smaller and enable the generation of heating and a spark in the vicinity of the inlet to be inhibited by fixing a flat inhibit plate to the lower portion of a bearing and making the interval between the inhibit plate and a heating chamber bottom surface smaller than the interval between the inhibit plate and a turn table. CONSTITUTION:A flat inhibit plate 9 of a metal plate which is fixed to the lower portion of a bearing 8 divides microwave electric power which enters space between a turn table 7 and a heating chamber bottom surface 1, into the upper and the lower. The smaller the interval h1 between the inhibit plate 9 and the heating chamber bottom surface 1 is made than the interval h2 between the inhibit plate 9 and the turn table 7, the more microwave electric power passing through between the inhibit plate 9 and the heating chamber bottom surface 1 and reaching the through hole 2 of the heating chamber bottom surface 1 is reduced. With this arrangement, abnormal heating and the generation of a spark in the vicinity of a choke cavity inlet provided in the through hole can be inhibited for a long time.

Title: U-shaped ferrite core
Inventor: HOSOZAWA TAKASHI
IPC: H01F27/24
Filed: 1996-04-04
Abstract: PROBLEM TO BE SOLVED: To obtain a gap having a high productivity and a high dimensional precision by making the abutting surfaces of legs form a continuous arc, and forming flat surfaces at the outside parts of the abutting surfaces of both legs. SOLUTION: A U-shaped ferrite core 1 has two legs 2, and the abutting surfaces of the legs are formed so as to have the shape of arcs 3. These surfaces 3 in the shape of arcs are formed on one virtual line. Flat parts 4 are formed at the outside parts of the abutting surfaces of both legs 2. And a gap is formed by the difference between each flat part 4 and the lowest part, and this gap is made so as to be equal to or longer than 1μm. For this working method, a cup diamond forming a diamond grinding stone is used, and its rotation axis is tilted against a perpendicular to the reference surface of a surface to be ground of the U-shaped ferrite core 1 by an angle θ. The cup diamond rotates, causes the U-shaped ferrite core 1 to pass in the direction of C or D, and works the whole abutting surfaces.  By doing this way, gap formation by only one continuous grinding becomes feasible, and it becomes possible to obtain a U-shaped ferrite core having high-precision gaps.

Filed: 1986-04-11
Abstract: PURPOSE:To increase the working area compared with a case where the locus control is performed by a specific arm only by selecting a pair where both two arms can be driven based on the angle signals supplied the prescribed priority. CONSTITUTION:The speed command signal set in a prescribed direction of the locus controlled system area is supplied to an angular velocity arithmetic means 60 from a command means 30 together with the angle signal showing the relative angle of each arm supplied from an angle detecting means 40. The means 60 selects a pair where both two arms can be driven according to the prescribed priority and based on at least the input angle signal out of those pairs of arms. Then the means 60 calculates the angle speed command signals of two arms based on both speed and angle command signal and outputs them. These speed command signals are converted into the input signals by an input signal arithmetic means 70 and outputted to a control part 50. The part 50 gives the locus control to a pair of arms 2 and 3 with priority. When the arm 3 reaches its stroke end, the locus controls is carried out by a pair of arms 1 and 2. Then the locus control is carried out by a pair of arms 1 and 3 when the arm 2 reaches its stroke end.
