Title: Ultrasonic flaw detector
Inventor: SUGA TETSUYA
IPC: G01N29/04
Filed: 1981-04-13
Abstract: PURPOSE:To permit flaw detection of a material to be examined which is welded partially in a circumferential direction automatically over the entire area by detecting the  flaws for one circumference of the entire part of said material including its unwelded  parts as a flaw detection range and subtracting a correction value from the results of  said flaw detection. CONSTITUTION:A material to be examined which is welded partically at plural joining  parts of a base metal 1 and a base metal 2 is rotated with a motor 5, and is subjected  to flaw detection with a probe 8 fixed in a water tank. The ultrasonic signal obtained  with the probe 8 is processed with a flaw detector 9, and from the results of the flaw  detection for one circumference, the sums of the number of defects in the weld zones  and the number of the false defects in the unwelded parts are counted in a defect  number counter circuit 10. On the other hand, the false defect number of the unwelded  parts determined from a test piece of the perfect weld zones is beforehand stored in a  memory 16 for correcting defect number and the content of the memory 16 is subtracted from the count value of the circuit 10 in a subtractor 17, after which it is compared with the output of a decision reference setter 18 in a non-defective/defective  decision circuit 12. Thereby, the weld zones welded discontinuously are detected of  flaw with virtually no unexamined areas.

Inventor: HASEGAWA MASATO
IPC: H04N7/167
Filed: 1997-03-10
Abstract: PROBLEM TO BE SOLVED: To more improve convenience for users by executing the reproduction of data in the state of automatic scramble only when it is desired by the user on the side of reproduction in the case of supplying and reproducing MPEG data. SOLUTION: In the MPEG data inside a TS supplied to an information reproducing device 100, key information showing whether or not outputting is to be allowed in the scramble state at the time of reproduction can be set to a scrambling contorl field inside a packet header. When the user operates a key input part 174, at the information reproducing device 100, outputting can be set for showing whether or not supplied MPEG data are to be outputted while being scrambled. At the time of reproduction, based on key information set to the scrambling control field and the state of output setting, only when the both are corresponding to the output in the scramble state, the supplied MPEG data are defined as the output of scramble state.

Title: Coated super hard alloy member
Inventor: HARA AKIO
IPC: C23C16/32
Filed: 1980-04-28
Abstract: PURPOSE:To obtain a coated super hard alloy member with enhanced bending strength, etc. for a tool, etc. by coating the surface of a hard alloy with a hard carbide layer having a specified thickness and further coating the layer with a specified metallic oxide as an outer layer.

IPC: H05K3/06
Filed: 1988-03-09
Abstract: PURPOSE:To uniformly eliminate and process sludge, by eliminating etching residue generated at the time of etching, by using a solution wherein hydrogen peroxide solution of volume concentration 5-35% and specified acid or alkaline solution are mixed. CONSTITUTION:On an insulating substrate 1, a thick film paste is formed, then a resist 4 is patterned, and a pattern 3 is formed by etching the resist 4. In this process, a component added in order to improve the adhesion of the thick film paste to the base insulating substrate is left as sludge 2 on the insulating substrate surface, without being etched. Therefore, after resist exfoliating process, the substrate is dipped in a mixed solution wherein hydrogen peroxide solution (volume concentration 5-35%) and nitric acid solution (volume concentration 30-100%) are mixed with volume ratio of 1:2, and sludge elimination processing is performed. As a result, a substrate surface without sludge is obtained, thereby enabling the uniform sludge elimination processing on the whole surface.

Title: Bend-working method for closed cross-section structural member and closed cross-section bending structural member
Inventor: MAGARA SHUICHI
IPC: B21D7/06
Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To bend a closed cross-section structural member without generating a recessed buckling on a bent surface even in bending the closed cross-section structural member in a post shape, and to increase an energy absorption quantity when an impact compressive load is acted on the bent closed cross-section bending structural member. SOLUTION: After forming plural holes 12 with a prescribed interval on a surface 11a scheduled to be bent of a closed cross-section member 11 in the post shape and on its opposite side 11b almost at right angle to a bending angle around a center point scheduled to be bent, since the surface scheduled to be bent is bent in the bending direction, the recessed buckling can be prevented from generating, and at the time of bending, workability can be improved by lowering the maximum value of bending resistance. Therefore, it is not necessary to prepare a lot of dies for bending, and little labor and time is required. Also, for the closed cross-section bending structural member 13, the plural holes 12 for absorbing an impact compressive force have been formed on the bent part of the bent closed cross-section bending structural member.  Therefore, the buckling is made to proceed in a bellows shape and by stepwise, and the energy absorption quantity at the time of an impact is remarkably increased. Also, when reinforcing the inside surface of the closed cross-section bending structural member 13 by lining a reinforcing member, reinforcing working can be easily performed because there are no projecting and recessing parts.

Abstract: PURPOSE:To reduce the number of gas monitoring section and necessary machine while ensuring power interruption range of bus or line at the time of maintenance or inspection by integrally setting line machines, bypass disconnector and an auxiliary bus disconnector in a first gas monitoring section whereas setting only a main bus disconnector in a second gas monitoring section. CONSTITUTION:A line disconnector 4, a bypass disconnector 6 and an auxiliary bus disconnector 8 are integrally set in a first gas monitoring section by employing insulating spacers 6a, 6b, 6c which can communicate gas freely, whereas only a main bus disconnector 7 is set in a second gas monitoring section. Consequently, construction of each machine and associated monitoring units can be simplified as compared with conventional system where each machine is set in individual gas monitoring section. Furthermore, since first and second gas monitoring sections are set independently at the sides of main bus 1 and auxiliary bus 2, power interruption is required at only one gas monitoring section at the time of maintenance or inspection of machine.
