IPC: H04N1/23
Filed: 1985-10-22
Abstract: PURPOSE:To realize a printing system in which a printer head part having plural diagonally arranged light emission dot groups is scanned in the row direction to print by rearranging the printing data supplied according to a printing block of a photosensitive drum in accordance with the number of columns of the light emission dot groups of the printer head part and the arrangement of the dots in the row direction. CONSTITUTION:A rotation direction of the photosensitive drum B is set to a direction of F and the printing blocks P (L, M) of a paper E and the photosensitive drum are addressed by reference making a left upper corner shown in the paper E a reference. Therefore, the arrangement of the printing data applied with respect to one scanning of a vacuum fluorescent tube A is obtained in such a manner that while only values corresponding to the number of columns of the emission dots are skipped with respect to the row direction, the printing data is rearranged in an increasing direction and while only values corresponding to multiples of pitches of the light emission dots in the row direction to the dimension of the light emission dots are skipped with respect to the row direction, the printing data is rearranged in a decreasing direction.

Title: Combustion device
Inventor: KURODA YOSHIYUKI
IPC: F23N5/12
Filed: 1984-11-09
Abstract: PURPOSE:To make a precision sensing of a flame condition and to provide a combustion device with a high safety by a method wherein a flame sensor is positioned in an oxidization flame formed between a plurality of flame holes made in a burner head and at an interrupted part of the flames. CONSTITUTION:When a flame 22 is lifted due to an excessive air or a reduction in concentration of oxygen, the oxidation flame 22a between the flame holes 18 is completely separated, the extremity end 23 of the flame rod 20 is positioned at the interrupted portions of the oxidation flame 22a and reduction flame 22b. As a result, a resistance value between the burner head 16 and the extremity end 23 of the flame rod 20 is rapidly increased and the lifted condition of the flame can be apparently detected. Since the extremity end 23 of the flame rod 20 is positioned between the flame holes 18 and placed out of the flow of the flame, so an effect to restrict the lifting of the flame is not produced. Therefore, it is possible to perform a better precise sensing of the condition of the flame, resulting in providing a combustion device with a high safety characteristics.

IPC: B08B3/10
Filed: 1993-09-22
Abstract: PURPOSE:To clean the filter without detaching it by discharging the water in a water injection nozzle by the pressure generated when the water is heated by a heater and bubbled. CONSTITUTION:When a filter 7 is increasingly contaminated, a signal is transmitted to a water feed pump 13 from a microcomputer having received a detection signal from a contamination sensor 19, the pump is started to suck up the water in an auxiliary tank 9, and the water begins to discharge from the tip of a water injection nozzle 15. A heater 16 is then energized by the microcomputer, hence the water in the nozzle 15 is heated, and the water in the nozzle 15 is instantaneously bubbled. Consequently, the water in the nozzle 15 is instantaneously increased in pressure, and the water in the nozzle 15 forms a waterdrop bullet by the pressure which is discharged against the filter 7 at a high speed. The dust stuck to the filter 7 is removed by the impact of the bullet, dropped into a drain pan 17 and discharged outside along with the drain water.

Title: Disk for recording
Inventor: KATO YOSHITAKE
IPC: G11B23/00
Filed: 1990-09-10
Abstract: PURPOSE:To prevent centering from being missed by forming a a circular arc shaped contact part with a rotary shaft for the positioning side of a rotary shaft inserting hole and providing a circular arc shaped part having a contact on the outside rather than the midpoint. CONSTITUTION:Circular arc shaped parts 10 and 11 are formed at positioning sides 6a and 6b and on the outside of a midpoint 10a of the circular arc shaped part 10, however, the circular arc shaped part 10 is formed so that a contact P can be positioned. Therefore, since an angle theta formed by lines/dropping from a central point O1 of a rotary shaft 8 to respective contacts P and P is larger than 90 deg., an area surrounded with this angle theta is wider than the conventional area. Thus, since the direction of the reaction of force operated onto a hub can be settled within this area, the hub is moved and centering can be prevented from being missed.

Title: Collision preventing method of wheel spindle stock side part portion with work table side part portion in cnc cylindrical grinding machine
Inventor: YAMAMOTO MASARU
IPC: B23Q11/00
Filed: 1998-08-24
Abstract: PROBLEM TO BE SOLVED: To prevent both part positions from colliding with each other by providing a measuring device for measuring the turning angle of an upper table to be one part of a work table, and obstructing approach over an allowable range between the part positions of a wheel spindle stock side and the work table side based on the measured information of the control device. SOLUTION: When the turning angle of an upper table 6 is zero, the coordinate values of a point positioned on the right end of the front end edge of the upper table 6 as a specific part position on the work table side are set to be (u, v). Next the coordinate values of a fixed longitudinal shaft 5 are set to be (a, b), The coordinate values of the specific part position p1 on the wheel spindle stock side in the Z-X coordinate system are set to be (S, T). The movable range in the x-axis direction of the wheel spindle stock 3 without generating collision is obtained from a formula: T>(u.cosθ-V.sinθ)tanθ+V/cosθ+b. Where, θ is the turning angle of the upper table 6 measured by a rotary encoder 10. Hereby, the specific part portion p1 on the wheel spindle stock side and the specific part portion p2 on the work table side do not approach exceeding respective allowable ranges for movement, and hence collision is prevented.

IPC: G11B5/64
Filed: 1986-10-06
Abstract: PURPOSE:To obtain a titled medium having excellent magnetic characteristics such as coercive force and squareness ratio of the medium even if a film forming speed is increased by incorporating chromium (Cr) and nitrogen (N) simultaneously into a thin magnetic cobalt nickel (CoNi) film. CONSTITUTION:The thin magnetic film consists of <=30atom% Ni, 2-20atom% Cr, and the balance essentially Co and contains 7-20atom% N (nitrogen). The thin alloy film contg. nitrogen is formed on a substrate by a film forming method such as sputtering in a gaseous Ar atmosphere contg. N2. The film is thereafter subjected to a heat treatment to release the required quantity of the nitrogen by which the magnetism is realized. The content of the nitrogen in the thin film to be formed on the substrate is preferably adjusted to 30-50atom%. The thin film consisting of a fine amorphous or crystalline substance is formed if a large quantity of the nitrogen is incorporated into the thin film at the time of sputtering in the above-mentioned manner. This thin film forms the magnetic recording medium having the adequate coercive force Hc and the high squareness ratio by crystallization or grain growth in the heat treatment of a post stage.
