Title: Manufacturing of etched part
Inventor: YAMAMOTO TATSUHIKO
IPC: C23F1/00
Filed: 1995-03-14
Abstract: PURPOSE: To provide a manufacturing method for a etched part, which is free from a faulty etching process, by cutting the right and left end areas of a metallic member so as to be removed after a regist film forming process but prior to an etching process. CONSTITUTION: Two paired circular knives 2 which are rotated in the direction identical to the carrying direction of metallic raw material 1 while being interlocked with a drive motor 4, are positioned at both plate end sections of the metallic raw material 1 respectively, and the plate end sectional areas are thereby cut and removed while the metallic raw material is passed through each paired circular knives 2. And only the area where the thickness of its regist film is as specified, and furthermore the regist film is uniform in thickness, is permitted to be passed through.  By this constitution, the area where the regist film is thin in the plate end sections 5 is prevented from being unnecessarily etched, the regist films at the plate end sections which are peeled off are prevented from being adhered again onto the metallic raw material, and thereby faulty etching is prevented, which is caused by adhered matters preventing etching to the metallic raw material.

IPC: A63B102/02
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To make the surface side and the rear side of a face give different repulsive and rotational forces to a ball, respectively by providing a double face by providing two rows of holes at necessary positions of the frame of a racket and passing strings each having a different diameter, into the holes. SOLUTION: A face 3 is provided doubly by providing two rows of holes at necessary positions of the frame of a racket and passing strings 2 through the holes. At such time, the strings 2 differing in diameter are used for the surface and rear sides and thereby gives different repulsive and rotational forces to a ball, making it possible to make different shots. One whose backhand swing is weak can select to hit a ball with a softly tensioned face. As the diameter of the strings can be made smaller than a single face by aligning the strings of a double face, a low air resistance easy swing can be made.

Title: Connector heat-crimping method
Inventor: ONIZUKA YASUTO
IPC: H05K3/36
Filed: 1997-03-10
Abstract: PROBLEM TO BE SOLVED: To provide a connector heat-crimping method in which elongation control of a resin film at the time of heat crimping can be properly performed to eliminate positional dislocation of a terminal on a substrate to a lead on a connector for improving production yield. SOLUTION: A width size of a terminal line 30a on a substrate 11 is set to be a little larger than a width size of a lead line 31a on a connector 12, heat-crimping is performed by a heat-crimping load to allow thermal expansion of the connector 12 while detecting above two sizes in an optical way, and when the two sizes coincide with each other, heat-crimping is performed at such a strong heat-crimping load that thermal expansion is not allowed. Size difference between the lead line 31a on the connector 12 and the terminal line 30a on the substrate 11 can thus be corrected in a simple method of changing the heat-crimping load to reduce generation of defectives by dislocation of a terminal 30 on the substrate 12 from a lead 31 on the connector 12, and improve production yield.

Title: Acaricide
Inventor: TANAKA YUICHI
IPC: A01N37/02
Filed: 1990-03-06
Abstract: PURPOSE:To obtain a new acaricide having excellent action on Dermatophagoides and Tarsonemidae, being a naturally occurring component, having high safety to human and animals, comprising a benzyl acetate as an active ingredient. CONSTITUTION:A new acaricide comprising a benzyl acetate as an active ingredient. Since benzyl acetate as the active ingredient of the acaricide vaporizes by itself and has acaricidal actions, benzyl acetate can continuously be scattered by self-vaporization as a composition having surface area corresponding to width of room to be sprayed. Consequently, the number of places injected with the acaricide in TATAMI (mat) can be lessened. The acaride in cotton of FUTON (thick bedquilt) can effectively be controlled and the residual acaride after treatment can be eliminated in a short time because of rapid vaporization. The acaride is safe to human and animals because of a naturally occurring substance.

Title: Electron beam apparatus
Inventor: ISHIZUKA TOSHIHIRO
IPC: G01R19/00
Filed: 1988-03-10
Abstract: PURPOSE:To improve accuracy in voltage measurement, by arranging a pair of lead-out electrodes on both sides of the maximum value of a magnetic field, and arranging a buffer electrode in the vicinity of the maximum value of the other magnetic field, and inputting secondary electrons into an analyzing electrode approximately vertically. CONSTITUTION:A pair of lead-out electrodes 43A and 43B are arranged on both sides of a first maximum value BZ1 which is located at the side of a sample to be checked 15. The same voltage phi is applied to the electrodes 43A and 43B. An equipotential space is formed between both electrodes. As a result, secondary electrons 20 emitted from the electrode 43A advance in an equi-strength electric field to the electrode 43B. Therefore, the dispersion of the secondary electrons is effectively prevented. Therefore, the speed of the secondary electrons is reduced with a buffer electrode 45 and condensed in the vicinity of the electrode. At this time, since a second maximum value BZ2 of a magnetic field is present in the vicinity of the electrode 45, the condensing degree is small. Thus, the secondary electrons passed through the electrode 45 maintain the approximately collimated state. As a result, the electrons are inputted into an analyzing electrode 47 approximately vertically, and the problem of 'slant input' is resolved. In this way, accuracy in voltage measurement is improved.
