Title: Ion implantation apparatus
Inventor: MIZUTANI HIROSHI
IPC: H01L21/265
Filed: 1990-09-13
Abstract: PURPOSE:To improve the dose uniformity in a wafer face by deflecting ion beams horizontally and vertically by an electric field generated by application of voltage in sine wave with a prescribed amplitude to scan the beam on an eddy track, and making ion beams which are deflected by a prescribed magnetic field in parallel each other. CONSTITUTION:In two pairs of electrodes 3, 4 in horizontal and vertical directions, while ions pass the beam deflecting system, the track of the ion beam is changed horizontally and vertically and draws an eddy owing to an electric field by voltage in sine wave whose amplitude becomes smaller as time passes. Further, Lorenz-force works on the vertical direction against the ion proceeding direction as well as a magnetic field due to the magnetic field of a lot of permanent magnets 6a whose intensity and direction change synchronously with the displacement of this electric field and the proceeding direction is curved, so that the direction and the intensity of the magnetic field 14 are controlled synchronously with the deflection of the electric field and the ion beams become in parallel each other. Consequently, ion beams enter into a wafer with a constant incidence angle and the tracks of the beams do not cross and the dose uniformity in the wafer 1 face is heightened.

Title: Temperature controller for liquid crystal optical shutter
Inventor: INOUE HIDEAKI
IPC: G05D23/24
Filed: 1985-10-29
Abstract: PURPOSE:To shorten a warm-up time and to prevent overshooting by forming the 1st and 2nd control means for detecting temperate at a position close to a liquid crystal shutter and changing a current supplying ratio to a heating means in accordance with the temperature. CONSTITUTION:When a power supply for a recording device is turned on, current is continuously supplied to the heater 19 until the temperature of the liquid crystal optical shutter reaches 43 deg.C on the basis of the control operation of a heating control part 31 to heat the liquid crystal, optical shutter within a short period. Consequently, the warm-up time can be shortened. The current supply ratio to the heater 19 is reduced by the 2nd temperature control part 35 before the temperature of the optical shutter reaches the set temperature to prevent the generation of overshooting which may be generated when the temperature of the optical shutter is suddenly increased. When the optical shutter is heated up to set temperature 45 deg.C, accurate control is executed by the 1st temperature control part 34, and when the temperature of the optical shutter exceeds the set temperature, current supply to the heater 19 is stopped by the temperature control part 32. Thus, the operating characteristics of the liquid crystal optical shutter is stabilized and the density of a recording image can be prevented from dispersion.

Title: Picture processor
Inventor: TANIOKA HIROSHI
IPC: H04N1/40
Filed: 1983-12-26
Abstract: PURPOSE:To obtain a picture processor which can identify accurately a mesh picture from a character (line) picture by identifying accurately different image areas and performing the proper picture processing in response to the picture tone. CONSTITUTION:An original picture is read by a scanner SC and stored temporarily in a picture memory GM after A/D conversion. Then the picture element data is extracted out of the memory GM by a microprocessor GP to form a block of (8X8) picture elements. Each picture element data within each block is binary coded by the fixed threshold value, and the sum total S of inverting times is obtained and the picture is identified. It is judged that the corresponding block is equal to a mesh image area in case the total S is larger than the fixed value P1. The average density value of the block is obtained and replaced with each picture element data within the block. A character image area is judged when the total S is larger than a certain constant P1 and smaller than another constant P2. Then the binary data is extracted as it is.

Title: Metal oxide film for suppression of scale adhesion
Inventor: OHIRA TATSUYA
IPC: C25D11/38
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To lessen and prevent the adhesion of scale, such as magnetite, in water in atomic power, thermal power, chemical plants, etc., by forming metal oxidized films which have crystal structures different from the scale, i.e., cubic type crystals, have face bearings to make the oxygen arrangement point- asymmetrical and of which the metal atom species are chromium. SOLUTION: These metal oxidized film materials on apparatus surfaces are metal oxidized films which have the crystal structure different from the scale particle, has the face bearing to make the oxygen arrangement point- asymmetrical and of which the metal atom species are the chromium or titanium. If the metal oxidized films satisfying these conditions are formed, the energy barriers by the coulomb repulsion between the scale film boundary oxygen are easily formed and the iron oxide scale adhesion is suppressed. If the surfaces of the plant apparatus are coated with chromium, and the chromium is subjected to an oxidation treatment, the chromium oxide films (hexagonal crystals) are formed thereon. The adhesion of the scale of the iron oxide, etc., may be lessened and prevented by these films.
