Abstract: PURPOSE:To enhance the high integration of a semiconductor integrated circuit by a method wherein a via hole used to connect interconnection layers to each other is arranged on a diffusion layer. CONSTITUTION:An N-type diffusion layer 2 is formed selectively on a P-type Si substrate 1; an oxide Si film 3 is formed on the surface including the layer 2. Then, a polycrystalline Si layer 6 is formed selectively on the film 3 in the central part of the layer 2. Then, an insulating film 4 is formed on the surface including the layer 6; the film 4 and the film 3 which are situated at the outer circumference of the layer 6 are etched sequentially to make a ring-shaped contact hole 5. Then, a contact electrode 7 is formed selectively on the surface including the hole 5 so as to be connected to the layer 3 in the hole 5. Then, an interlayer insulating film 8 is formed on the surface including the electrode 7; a via hole 9 is made in the film 8 on the layer 2. Then, an interconnection 10 extended on the film 8 so as to be connected to the electrode 7 in the hole 9 is formed. By this constitution, even when a pinhole produced at the electrode 7 passes the film 4, it is stopped by the layer 6 and it is possible to prevent the layer 2 from being etched.

Title: Forgery and falsification preventing card
Inventor: KOSUGI TAKUMI
IPC: B42D15/10
Filed: 1996-02-13
Abstract: PROBLEM TO BE SOLVED: To obtain a card which can be scarcely forged and prevent the falsification by arbitrarily embedding a perforated hole to write information by drawing an inner pattern so that the previously drawn pattern cannot be externally observed. SOLUTION: In the card such as a prepaid card, a pattern which cannot be externally observed is drawn therein to enhance the security. To prevent the falsification by incorrectly embedding a perforated hole to write information, the pattern is crossed at the hole so that the pattern is preferably difficult to be recovered even if the hole is embedded, and fine foire pattern, lattice foire pattern, oblique lattice foire pattern, network pattern, or waterdrop pattern can be used. As a method for drawing the pattern, a printing method, an etching method using a photoresist, or a method for optically curing by using a photomask is adopted.

Title: Negative radiation sensitive composition and pattern forming method by using the same
Inventor: UCHINO MASAICHI
IPC: C08L61/06
Filed: 1998-03-04
Abstract: PROBLEM TO BE SOLVED: To enable the formation of <=0.2 mm-sized fine patterns high in dimensional precision by using specified polyvalent phenol and tertiary polyhydricalcohol having a hydroxyl group on a C atom directly combined with an aromatic ring and an acid precursor. SOLUTION: This pattern forming method uses a negative radiation sensitive composition comprising polyvalent phenol obtained by condensing a phenol compound represented by formula I and a phenol compound represented by formula II with formaldehyde, tertiary polyhydricalcohol and an acid precursor. In formula II, R1 is an H atom or a CH3 or C2 H5 group. Since this poly-valeut phenol is smaller in molecular weight by about one order than the thermosetting resins used in conventional techniques, the roughness on the side walls of resist patterns can be remarkably reduced by using this polyvalentphenol as a matrix component. As this tertiary polyhydricalcohol, polyhydricalcohol having a hydroxyl group on a C atom directly combined with an aromatic ring, is preferable and the polyhydricalcohols having a molecular weight of <=200 and small sublimability are more preferable.

IPC: G01C3/06
Filed: 1994-03-23
Abstract: PURPOSE:To immediately recognize the position of an obstacle by marking an object interfering with vehicle traveling on an image in a monitoring area. CONSTITUTION:When there is no object on a road, a luminescent point(LP) obtained from a photographed spot is previously recorded in a reference data recording part 13. When image pickup is executed by a camera 11, an LP extracting part 14 successively reads out respective picture elements recorded in a frame memory 12, compares the picture elements with a prescribed threshold and extracts a low LP part. Then the extracting part 14 calculates the center-of-gravity position of luminance of each picture element surrounded by low luminance picture elements and records the center-of-gravity position as an LP position. Then a moving LP extracting part 15 compares the LP position recorded in the recording part 13 with a position obtained by photographing the periphery of a vehicle and records a moving LP. An object position calculating part 16 calculates the three-dimensional position of the moving LP, and when an obstacle judging part 17 judges the existence of danger of collision, an obstacle marking part 18 marks an obstacle.

Abstract: PURPOSE: Cylindrical metal member work hardening process utilizes a repeated plastic deformation into oval shape by using a specific, radial, symmetrical pressurization. Such process eliminates the need for conventional expensive equipments, enabling easy and positive work hardening.  
     CONSTITUTION: A cylindrical matal member 21 of plastically work hardenable material is pressed into an oval shape 21 by a pair of plate 21-having presses 22, 23 in the symmetrical direction 1-9 which is one of the equally devided cylinder's radial directions. Next, the cylinder is pressed in the direction 5-13 right angle to the direction 1-9, then in the direction 1-9 to recover its circular shape. Equally devided directions are used in sequence to plastically deform the cylinder material. The number of directions can be selected properly according to the height H. Thus, the process enhances high strength and abrasion resistance, high accuracy cylindrical metal member work hardness, without the need of pipe expansion and contraction as well as expensive tools and fixtures.
