Title: Magnetic head, magnetic head manufacturing method and magnetic disk
Inventor: MAKITA TOKIFUMI
IPC: G11B5/265
Filed: 1997-11-19
Abstract: PROBLEM TO BE SOLVED: To obtain the magnetic head having an excellent offtrack overwrite characteristic by forming the upper part magnetic layer, the recording gap layer, lower part and upper part high saturation magnetizing layers adjacent to the recording gap layer of a recording head part so as to have the same width in a track width direction. SOLUTION: Photoresist frames 21a, 21b having a track width 30 are formed on a lower part magnetic layer 1. Next, a lower part high saturation magnetizing layer 2, a recording gap layer 3 and an upper part high saturation magnetizing layer 4 are successively formed. Next, an upper part magnetic layer 5 is formed in the interval part having the track width 30 between the photoresist frames 21a, 21b. The lower part high saturation magnetizing layer 2, the recording gap layer 3 and the upper part high saturation magnetizing layer 4 formed in this manner are formed so as to have the same width as that of the upper magnetic layer 5 in the track width direction.  Thus, since the magnetic flux at the time of an information recording can be concentrated in terms of the same width and the track width direction, a recording blotting is reduced and a magnetic head having an excellent recording characteristic is obtained.

Title: Pattern lithographer
Inventor: TAKASHIMA SHINJI
IPC: G09G1/00
Filed: 1987-12-18
Abstract: PURPOSE: To increase the pattern drawing speed by providing a circuit which matches 1-line data outputted from a pattern storage device with drawing pixel coordinates and adjusting positions, pixel by pixel, and ORing the data with data in a drawing area. CONSTITUTION: Drawing data 18 outputted by a selector 15 are ORed by an OR circuit 16 with data read temporarily out of an area the be drawn, and drawn after being written. This is to protect data, drawn in an image memory 2 before, against disappearance due to pixel data other than 1-line data 12 in extension data 17. Thus, even a system which performs drawing to the image memory 2 in an X-coordinate direction only at certain intervals can draw plural pixels at the same time in pixel coordinate units. Consequently, the pattern drawing can be performed at a high speed.

Title: Pattern exposing method and electron beam exposure system
Inventor: OSHIMA TORU
IPC: G03F1/76
Filed: 1995-12-07
Abstract: PROBLEM TO BE SOLVED: To shorten the total exposing time by determining the split transfer number for X and Y sorting directions and arranging the field along the direction where the split transfer number is lower thereby correcting the block transfer number. SOLUTION: The split transfer number (BTN) is calculated for X and Y sorting (S) directions and the direction of a smaller number is designated as 3 correction. Exposure data(ED) is then decomposed and a field is arranged in the designated direction. Subsequently, the quantity of ED is compared with the capacity of the memory (KM) in an electron beam exposure system and when KM>=ED, all ED is transferred at once in the designated direction S and all data is exposed thus ending the operation. When KM<ED, a split ED for one time is transferred to the KM along the direction of the lower BTN and a decision is made whether a predetermined BTN has finished at the end of exposure. If it is not finished, the next split ED is transferred and exposed and all exposure is ended when the predetermined BTN is finished.

Title: Automatic focus adjustor
Inventor: NISHI HIDEO
IPC: G02B7/28
Filed: 1988-12-16
Abstract: PURPOSE:To preclude disablement of focusing in macrophotography and to attain high-accuracy automatic focus adjustment by providing an area setting means, a mode detecting means, and a control means and changing a detection area automatically between normal photography and macrophotography. CONSTITUTION:The signal from an image pickup element 20 is passed through a video signal processing circuit 21 and part of it is inputted to a contrast detecting circuit 22 through an area gate circuit 23. An AF control circuit 25 puts a lens in focus by sending its output to a lens driving part 26 so as to move the focusing lens 11 to the position where the contrast value is maximum with the output signal of the circuit 22. The circuit 23 switches a video signal with the signal of the circuit 25 to extract only the signal of a necessary area. Here, the circuit 25 detects macrophotography time (whether a macrophotography switch 19 is on or the lens is moved to the macrophotography side) and sends its output to the circuit 23 so that the detection area is widened at the start of AF operation. In the normal photography, the detection area is switched to a narrow detection area. Consequently, the failure in focusing in macrophotography is precluded and high-accuracy AF operation is enabled.

IPC: A61P1/02
Filed: 1990-11-21
Abstract: PURPOSE:To obtain a dentifrice for therapeutic treatment of pyorrhea capable of effectively curing pyorrhea without applying pain to the diseased part by using bittern as a main component. CONSTITUTION:The objective dentifrice is produced by using bittern as a main component, preferably kneading bittern with a proper amount of water to form a gel or further mixing 10-50% tooth powder based on 50-90% bittern. Since bittern is absolutely free from sodium chloride and is odorless and tasteless, the dentifrice does not cause pain at the diseased part of pyorrhea when tooth is brushed with a tooth-brush holding the dentifrice. Components of bittern such as magnesium salt, potassium salt, sulfate ion and bromine ion effectively act on the diseased part of pyorrhea to cure the disease.
