Abstract: PURPOSE:To perform a work on a polycrystalline silicon film to obtain the line width of 1 micron or below in a highly precise and excellent reproducible manner by a method wherein the polycrystalline silicon film is processed into the desired form using an oxide film as a mask, and after a high temperature heat treatment is performed in a nitrogen atmosphere with the oxide film attached, an etching is performed thereon. CONSTITUTION:An impurity-doped polycrystalline silicon thin film 2 is provided on a silicon substrate 1, the protective film 3 such as a silicon oxide film and the like is formed on the polycrystalline silicon film 2, and the pattern of the protective film 3 is formed using a photolithographic technique. Then, an etching is performed on the polycrystalline silicon film 2 using the protective film 3 as a mask, and the pattern of polycrystalline silicon having the protective film 3 placed thereon is formed. When a high temperature heat treatment is performed in nitrogen gas, the property of the polycrystalline silicon located at the part which is directly exposed to the nitrogen gas changes, and the speed of etching becomes very slow. When the protective film 3 is removed and the polycrystalline silicon film 2 is removed by performing an ordinary etching method such as a dry etching and the like, all the part other than the modified part 4 can be removed.

IPC: G11B20/10
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To use proper signal detection points for both high and low sides of an asymmetrical signal by independently detecting the respective sides of the asymmetrical signal by using an algorithm. SOLUTION: The threshold value voltage (5V) of the high side of an asymmetrical signal is adjusted downward until it is detected, then recorded and reset to a value close to a maximum value 22. The threshold value voltage (-2,5V) of a low side is adjusted upward until it is detected, then recorded, reset to a value close to a minimum value 24 and an algorithm is repeated for continuously monitoring signals. The gain of the reading amplifier of a threshold value adjusting circuit is adjusted by a controller so that the peak of a reference burst 16 accordingly gain-amplified is approximately equal to a specified value. The controller also controls the first horizontal direction position of a tape head assembly 10 on a magnetic medium 14 by using the digital sample of a reference burst signal level.

Title: Method and device for encoding contour
Inventor: KIM JIN-HUN
IPC: G06V10/46
Filed: 1996-10-01
Abstract: PROBLEM TO BE SOLVED: To reduce data volume by suitably masking discrete sine transformation(DST) coefficients in accordance with an output from a polygonal approximation process. SOLUTION: A masking control block 600 including a length calculation block 610 and a masking range setting block 620 calculates the length of each segment based on vertex information on a line L10 and generates a masking range setting signal for controlling a masking block 500 by using the length of respective segments and the number N (N is a positive integer) of segments. Each masked DST coefficient group corresponding to a DST coefficient group is generated by masking a prescribed part of each DST coefficient group or executing no masking in all of each DST coefficient group in accordance with the length and the number N. Each masked DST coefficient group is converted into a quantized DST coefficient group and each quantized DST coefficient group corresponding to each segment is encoded. Thus DST coefficients can be suitably masked.

Title: Refill of ball-point pen
Inventor: KOBAYASHI SEIICHI
IPC: B43K7/02
Filed: 1995-09-14
Abstract: PROBLEM TO BE SOLVED: To prevent blur of writing caused by running out of ink following upward writing and entrapment of air just under a tip ball by a method wherein a spring is inserted into an inner hole of a tip, and the tip ball held freely rotatably to the tip part of the tip is pushed to make the tip ball close to an inner fringe of a ball holding part of the tip. SOLUTION: Under a state wherein a tip 21 is turned up by a refill 20, since a tip ball is close to an inner fringe of a ball holding part of the tip 21, ink does not reversely flow upwards. Further, even though the tip 21 is turned downward, a direct flow of the ink does not occur. Under a state wherein the refill 20 is stored in a shaft, a rear end of an outside axle part 49b abuts against a front end of an abutting pin to advance a rear end of a spring 25 by pushing. Therefore, the tip ball 22 is strongly close to the inner fringe of the ball holding part of the tip 21 to prevent surely direct flow, reverse flow, and drying of the ink. Consequently bulging, uneven ink flow, blurs do not occur, and writing properties are improved.

Filed: 1985-11-20
Abstract: PURPOSE:To enable highly accurate positional alignment even in a color record ing type thermal transfer recording apparatus for repeatedly reciprocating recording paper, by making the feed speed of the recording paper by a feed roller higher than the moving speed of an ink sheet by a pinch roller. CONSTITUTION:The feed speed of recording paper 13, that is, the moving speed thereof by a first feed roller 16 and a second feed roller 17 is made slightly higher than the feed speed of an ink sheet 2, that is, the moving speed (v) there of by a feed roller 8.
