Title: Rivet forming tool for can lid
Inventor: OTSUKA HIDEO
IPC: B21D51/44
Filed: 1987-07-15
Abstract: PURPOSE:To prevent the generation of a flaw in the case of forming the org. film for corrosion-proof of the rivet inner face by composing at least a male die by a zirconia ceramic. CONSTITUTION:A pinch tab 3 is fixed by forming in the rivet 6 that the outer diameter d of a head 6a is larger than the inner diameter of a hole 3a by squeezing the vicinity of the head 2a of a projecting part 2 mainly by ascending an anvil 5. The org. film 7 for corrosion-proof is formed on the inner face side of a can lid 1. In case of squeezing, the head 2a of the projecting part 2 receives comparatively big compression deforming by being compressed by the bottom face 4a of a male die 4 and anvil 5. The film 7 of the rivet 6 inner face is hardly scratched by forming a male die at least by a zirconia ceramic because of a very small friction coefft. on the surface subjected to mirror finishing.

Title: Sheet feeding device
Inventor: KIKUCHI YUTAKA
IPC: B65H3/68
Filed: 1990-07-04
Abstract: PURPOSE:To avoid interference with the device body when a sheet cassette is loaded or removed and to reduce the overall height of the device by furnishing a cassette guide so as to be capable of moving vertically. CONSTITUTION:A cassette guide 35 mounted on a sheet cassette 26 with possibility of moving vertically is installed between a feed roller 31 and No.2 sheet transport path 33. The cassette guide 35 is energized upward with the resilience of a compression spring 36, and the upper part extends in the body frame. This cassette guide 35 forms a sheet feed path 4 to put a sheet P2 fed from the sheet cassette 26 by the feed roller 31 in continuity to the transport path 33. When the sheet cassette 26 is drawn out in the x-direction, the slope of the cassette guide 35 is depressed in the lower part of the body frame against the action of the spring 36 and is retreated. This avoids interference of the casette guide 35 with the body frame. Also the height of the inlet/outlet of the cassette can be lessened, which suppresses the overall height of the device.

Filed: 1986-07-28
Abstract: PURPOSE:To improve the stability of reproduction output in the longitudinal direction of a recording medium and the durable performance of the medium by subjecting a surface oxide layer to dry etching and forming a thin diamond- like hard carbon film immediately thereafter while moving a treating body disposed with a partially oxidized thin ferromagnetic metallic film on a high- polymer film along a rotary support. CONSTITUTION:While the treating body 6 disposed with the partially oxidized thin ferromagnetic metallic film 3 on the high-polymer film 1 is moved along the rotary support 10, the thin diamond-like hard carbon film 4 is formed on the surface oxide layer right after the dry etching of said oxide layer. The surface oxide layer is no longer etched and the thin film is controllable to the constant thickness in the process of forming the thin diamond-like hard carbon film 4. The magnetic recording medium which is stable in spacing is thereby obtd. The magnetic recording medium which is additionally improved in durability is surely obtd. if the spacing loss component by the surface oxide layer is equally distributed to the thickness component of the thin diamond-like hard carbon film 4.

Title: Composite mat
Inventor: SUGANAMI MASAJI
IPC: G06F3/039
Filed: 1996-06-04
Abstract: PROBLEM TO BE SOLVED: To prevent a slippage from occurring at a fitting position, and eliminate the problem of an elongation to a local stress, and further, prevent an environmental problem attributed to a noxious gas from occurring at the time of disposal by incineration by providing an anti-slip layer on one of the faces of a polyester elastomer resin sheet. SOLUTION: This composite mat consists of silicone resin 2 laminated as an anti-slip layer on one of the faces of a polyester elastomer resin sheet 1. The polyester elastomer resin sheet 1 causes a slippage at a fitting position, if it is used alone, hence an anxiety about its use. However, the anti-slip layer becomes part of a fitting member and allows the used of the composite mat without any anxiety. In addition, the composite mat is free from a soil sticking stubbornly to the surface of already existing articles and also a local elongation to be caused by the local stress which is unavoidably generated in an elastomer product because of its nature. Further, an environmental problem attributed to a noxious gas generated when the existing soft polyvinyl chloride resin product is discarded by incineration, is solved.

Title: Plasma cvd device and cleaning method for the same
Inventor: ARIYOSHI TOMOYUKI
IPC: H01L21/304
Filed: 1996-07-08
Abstract: PROBLEM TO BE SOLVED: To perform cleaning work in a short time by providing an impedance detecting means for detecting the change of impedance between a cathode electrode and an anode electrode. SOLUTION: When the films stuck on a cathode electrode 2 and an inner tank 5 are removed by self-cleaning, the capacitance of film is eliminated. Thus, the impedance between the cathode electrode 2 and the inner tank 5 is changed, so that the films stuck on the cathode electrode 2 and the inner tank 5 can be removed. Because of the removal, the increase rate or decrease rate of voltage Vpp or voltage Vdc temporarily becomes higher than a prescribed value and afterwards, when the films stuck on the cathode electrode 2 and the inner tank 5 are removed, the increase rate or decrease rate of voltage Vpp or voltage Vdc becomes lower than the fixed value. Therefore, the end point of self-cleaning can be detected. Thus, cleaning work can be performed in a short time.

Filed: 1999-06-24
Abstract: PROBLEM TO BE SOLVED: To enable quick convergent solution of an unconstrained minimization problem through Newton's method, by calculating a Jacobian matrix in advance through a power equation of the constraint with a demand balance, and by calculating gradient vectors and a Hessian matrix through using the Jacobian matrix. SOLUTION: After setting initial values (step 1), the unconstrained minimization of an extended Lagrange's function is executed subsequently, to denote the solution thereof by Kk (step 2). The comparisons of the specific values using the solution Xk with a threshold βCk are executed to check violation quantities with respect to an inequality constraint I or an equality constraint J. At this time, after calculating a Jacobian matrix in advance through a power equation of the constraint burdened by a demand balance, it is used to calculate gradient vectors and a Hessian matrix by Newton's method (step 3). Furthermore, by calculating search vectors dk (step 4), a linear search is conducted, and by calculating a step width t, the modifications of variables added by tdk are executed (step 5). Thereby, the optimum solution of a power flow can be calculated in a short time.
