Title: Dry-etching method for semiconductor device
Inventor: IKEGAMI NAOKATSU
IPC: H01L23/522
Filed: 1999-09-09
Abstract: PROBLEM TO BE SOLVED: To provide a via hole of stable form while occurrence of bowing near the TEOS oxide film/SOG film interface is prevented by using a mixed gas containing a specified gas of specified flow-rate when forming the via hole, by dry etching, on an insulating film where an organic SOG film is provided on the TEOS oxide film. SOLUTION: After forming a metal wiring which is to be a lower layer wiring 12 on a silicon substrate 11, a via hole 17 for conduction between an upper layer wiring and the lower layer wiring 12 is opened using a resist pattern 16 on an insulating film, where a plasma TEOS oxide film 13 and an organic SOG film 14 which are to be an interlayer insulating film are sequentially deposited on the metal wiring by dry etching. For dry etching with the via hole 17, the mixed gas of CHF3/CH2F2/CO is used. The mixing ratio of CH2 F2/(CHF3+CH2F2) is about 50% or more. With the mixing ratio as this, the via hole 17 is almost vertical.

IPC: B23K37/00
Filed: 1992-08-31
Abstract: PURPOSE:To prevent air from intruding into a cover and to hold the inner part of a line cover in an oxidation preventing atmosphere by blowing oxidation preventing gas into the periphery of a tube body, in an uncontinuous opening part of the line cover. CONSTITUTION:The opening part 6 to pass a kicker 8 of the tube body springing out device is mounted on a conveyor line cover X for a high temperature tube body 1 and the air which intruds from a clearance (a) into the cover X cannot be prevented by only a trough type cover member. A gas blow-in hole 7 is mounted on the cover 3 facing a uncontinuous part of the line cover like this and nitrogen gas is blown to the tube body 1 to keep this periphery in a oxidation preventing atmosphere. In this way, the concentration of oxygen in the cover can be reduced to <=2% in the whole area of the line cover X.

IPC: B21K1/30
Filed: 1993-10-14
Abstract: PURPOSE:To simplify a working process by forging and heading and to improve strength and durability by forming supporting shafts by drawing both ends of almost columnar blank, forming a gear with a small diameter on one end side of the center barrel part of a blank, making the other end enlarge to a large diameter by upsetting in a following process, and forming a gear with a large diameter on the enlarged barrel part. CONSTITUTION:In the forming of a gear 22 with a large diameter and a gear 21 with a small diameter, the gear 21 with a small diameter, is formed on one end side of the center barrel part of a blank 1 on which supporting shafts 20 and 20 are formed on both ends. In a following process, the other end of a blank barrel part, is allowed to enlarge to a large diameter by upsetting, and in a following process, the gear 22 with a large diameter, is formed on the enlarged barrel part. Consequently, since a working ratio is small, the flow of the material of the blank l at the time of forging and heading is smooth, a material is sufficiently filled to the tips of teeth of a gear, and a gear with high precision can be formed. Also, since the gear 21 with a small diameter, the gear 22 with a large diameter and the supporting shafts 20, are formed from one blank l by forging and heading a working process can be simplified.

Title: Inclined backing fixture for reducing impact on light receiving body and insertable cleaner provided with impact absorbing material
Inventor: FORNALIK ANTHONY C
IPC: G03G21/10
Filed: 1998-09-10
Abstract: PROBLEM TO BE SOLVED: To reduce or prevent a defect in the kinetic characteristic of a light receiving body caused by the impact between a cleaner spacer of the light receiving body and a backing member in a printer, etc. SOLUTION: The distance between a cleaner brush and the light receiving body (an image pickup surface, a belt, etc.), when the cleaner brush is moved in the direction of an arrow 105, is prescribed by a spacer wheel 100 and an inclined backing fixture 115. An impact absorbing material 180 prevents the instantaneous great impact force between the spacer wheel 100 and the inclined backing fixture 115, which may cause the defect in the kinetic characteristic of the light receiving body. The inclined backing fixture 115 gradually reduces the speed of the spacer wheel 100 by the inclination structure of the fixture 115. Therefore, the defect in the kinetic characteristic caused by the vibration of the light receiving body due to the impact when contact occurs is prevented. Thus, sudden speed reduction of the spacer wheel 100 with respect to the backing fixture 115 is prevented.  Both of the impact absorbing material and the inclined backing fixture are used to provide a more suitable state.

Title: Marking method
Inventor: YOKOTA TOSHIO
IPC: G06K1/12
Filed: 1986-10-30
Abstract: PURPOSE:To perform the printing of which is bridge part is eliminated by a simple process, by a method wherein at least one pulse of a laser beam irradiates any one of the three, i.e. a stencil, a projection, or treating matter to be marked by moving a bridge in a direction to be eliminated. CONSTITUTION:When a laser beam is irradiated on a stencil 2, a meniscus lens 3, and treating matter to be marked 4 as they are fixed to, for instance, a square frame having a bridge 5, the square frame having the bridge is printed on the treating matter to be marked 4. Then, when the laser beam is irradiated for a fixed time by moving the meniscus lens 3 vertically to a position of a dotted line 3', a pattern punched on the stencil 2 is projected so as to fill up vertically the bridge 5 without generating any blur since it is not moved in the cylindrical axis (lateral direction) of a cylindrical lens 1. Therefore, the printing of which the bridge part 5 is not conspicuous can be achieved. Since the width of the bridge 5 is very narrow and the direction of a narrow width is made as a moving direction, the bridge part is eliminated and a character pattern is clearly printed.

Title: Post-processing method for ocr-inputted japanese sentence
Inventor: ITO NOBUYASU
IPC: G06K9/72
Filed: 1991-09-10
Abstract: PURPOSE: To execute the post processing of a Japanese sentence inputted from an OCR at sufficiently high accuracy and speed. CONSTITUTION: After searching grammatically formed passes based upon a recognition result and the restriction of Japanese, the cost of each available pass is calculated and a plurality of candidate passes having suitable cost values are selected. Then the conviction Cf of each character candidate (or plural candidates) of each column is calculated from the cost g (1) of a candidate pass passing the character candidate itself (or the candidates themselves) and the cost g (2) of a candidate pass passing another character candidate (or other character candidates). Thus the substitution of candidates or warning to an operator is executed, based upon the calculated value.
