Title: Inspecting method for remainder of passivation film
Inventor: YOSHIDA HIDEAKI
IPC: H01L21/66
Filed: 1997-07-22
Abstract: PROBLEM TO BE SOLVED: To make it possible to confirm easily and surely whether or not a passivation film is perfectly bored by etching a bonding pad in which holes have been bored, inspecting whether or not this etching has been performed, and inspecting passivation film remainders on the basis of this. SOLUTION: A bonding pad 22 is formed on the surface of an Si chip 21. After holes are bored in a passivation film 23 formed on the bonding pad 22, metal used in the bonding pad 22 is etched. At normally-bored parts of the passivation film 23, the bonding pad 22 is etched, but at parts where there are passivation film remainders 24 the bonding pad 22 remains without being etched. So, it is possible to detect the passivation film remainders 24 by observing the bonding pad 22 by a microscope, etc.

Title: Reducing method of earth pressure of arch type culvert
Inventor: NAKAGAWA YOSHIHIRO
IPC: E03F3/04
Filed: 1992-06-12
Abstract: PURPOSE:To reduce working earth pressure, to decrease the thickness of a member and to diminish the quantity of a reinforcement used by forming the joining section of the arch member and bottom plate of an arch type culvert in hinge structure, in which a material shrunk by the pressing of foamed styrene, etc., is held. CONSTITUTION:The joining section of an arch member 1 and a bottom plate 2 is formed in hinge structure, in which shrinking materials 3, 4 composed of foamed styrene, etc., are held. When an arch type culvert is banked, axial tension is generated in the arch member 1 by the working of earth pressure, and the arch member 1 compresses the shrinking materials 3, 4. The lower end of the arch member 1 is sunk with the compressive deformation of the shrinking materials 3, 4 while being horizontally moved at that time. Consequently, the arch member 1 is displaced toward the inside of an arch. Soil is displaced while following up the displacement of the arch member 1, strain in the arch circumferential direction in soil in the vicinity of the arch is increased by the displacement, and stress in the same direction is augmented. Component force in the direction of the radius of curvature of the arch of the increased stress resists stress in the same direction, thus reducing working earth pressure.

Filed: 1981-12-04
Abstract: PURPOSE:To change the running direction of a strip safely and assuredly by sequentially disposing multistage rolls for guiding the strip vertically after a pay-off reel of line equipment and radially at a running direction changing corner portion. CONSTITUTION:A strip 2 drawn out from a pay-off reel 1 passes through rolls 3, 3-1, and then gets to a roll 3-2 a little inclined to the changing direction at a running direction changing corner portion to change its running direction a little. The strip is guided to upper and lower rolls 3-3, 3-4,...3-10 disposed radially centering around the center of the corner radius with phase sequentially shifted so that the course of the strip is changed to a desired direction, and the strip is rolled round a reel 4. By tension worked upon the strip in the widthwise at the corner portion, the end portion of the strip 2 is stretched out corresponding to the inclination of the rolls as against the central portion thereof, so that if the stress of the end portion is lower than the stress of yield point, the strip can be free from plastic deformation and turned to a different direction without the smallest strain.

Then, a fin 18 is gradually widened and its biting into the top part of the lock section 9 is started. Fitting of the fin is facilitated with a chamfered section 10 and it reaches the maximum biting force or it is reaching this value. Then, biting of the biting fin 18 at the lock section 9 is carried out well when a forced insertion of the sealing ring 16 into an orifice 6 is promoted and an inserting force caused by the snap-on effect is not yet produced. Lastly, the sealing ring 16 is well fitted into the orifice 6 and the biting fin 18 merely performs a sliding motion within either the recess or the slit and the pushing of the cap base 4 into the neck 2 can be carried out smoothly.

Title: Method of automatically inserting paper
Inventor: YOTSUTSUKA KOUSUKE
IPC: B41F33/06
Filed: 1985-09-04
Abstract: PURPOSE:To enable automatic paper insertion to be easily performed without requiring difficult control, by feeding a continuous paper at a velocity lower than the circumferential velocity of a transfer cylinder when inserting the paper through a gap between the transfer roller and a restricting member. CONSTITUTION:While an impression cylinder 11 is reset to a position apart from a blanket cylinder, a pin feed tractor 13 starts paper feeding at a low velocity of, for example, 1/4 of the velocity at the time of printing. Since the paper feeding velocity at the time of inserting the continuous paper 12 is extremely low, the paper 12 is struck in the moving direction thereof by the blanket cylinder 2 and the impression cylinder 11 when passing through the gap while making contact with the cylinder 11 under its own weight to be fed toward a suction conveyor 14. Accordingly, automatic paper insertion can be easily performed without any difficult control and without crushing the end of the continuous paper 12 even when a paper-discharging roller 206 is provided.
