Title: Method and apparatus for manufacture of metal oxide superconducting material layer
Inventor: IERUKU KIIZAA
IPC: C30B1/02
Filed: 1989-02-21
Abstract: PURPOSE: To manufacture a layer having a high critical current density freely to be regenerated by moving a reserve product at the predetermined speed in parallel with a surface of the layer through an area, which is formed with the positive maximum temperature gradient at 5K/mm (ΔT/Δx) measured in the moving direction and which is heated. CONSTITUTION: A reserve product V is moved at the predetermined speed (v) in parallel with a surface of a layer 3 through an area 14, which is formed with the positive maximum temperature gradient at 5K/mm (ΔT/Δx) measured in the moving direction. Namely in an area formed with the temperature gradient, in which the reserve product V is moved through the layer in parallel with the surface, forming of the anisotropic crystal structure is promoted in the current transmitting direction. As a result, the improved corresponding critical current density (current carrying force) exists in this direction. Critical current density in a coated board can be thereby desirably and easily improved.

Title: Motor drive
Inventor: MIYAZAKI HIDETO
IPC: H02P8/22
Filed: 1997-02-10
Abstract: PROBLEM TO BE SOLVED: To prevent step-out, abrasion of a gear, noise, and the like, of a stepping motor altering the exciting method to the exciting phase closest to the exciting phase before alteration if the exciting phase of exciting method before alteration does not exist in the exciting phases of an exciting method after alteration. SOLUTION: When a start signal is set to 1, a decision is made whether a current exciting phase is AB, /AB, /A/B or A/B. When the current exciting phase is any one of them, a pulse generator generates a two-phase excitation output. When the current exciting phase is different from any one of them, it is any one of AAB, A, AA/B, /BA/B, /B, /B/A/B, /A/A/B, /A, /A/AB, B/AB, B or BAB and the exciting phase is altered to a closest one in the rotational direction designated by that exciting phase. Consequently, the pulse generator generates a two-phase excitation output in synchronism with a motor drive pulse from a microprocessor.

IPC: G03F7/00
Filed: 1986-02-28
Abstract: PURPOSE:To eliminate the vacuum adhesion of a slip sheet onto the bach surface of a supporting body of a photosensitive printing plate and thereby to avoid an impediment inside an autoprocessor, by roughening the back surface of the supporting body of the photosensitive printing plate. CONSTITUTION:A method wherein paint prepared by dispersing powder in a dispersion medium is applied on the back surface of a supporting body, or a mechanical method such as a brushing method, is adopted as a method of roughening the back surface of the supporting body. In any case, a method according to which the roughened state of the back surface is eliminated before a printing operation is desirable. In the case when a coating method is adopted as a roughening means, the paint prepared by dispersing a roughening material by 1-40wt% in a dispersion medium such as water, an organic solvent, phenolic resin or water-soluble resin is applied on the back surface of the supporting body. In the case of a mechanical roughening method, a desirable condition is that average roughness on the center line be 0.2-20mum Ra. As for the roughening material, the particles of silicon dioxide, zinc oxide, synthetic high-molecular compound, organic foaming agent or the like are used therefor. The particle size of the roughening material is preferably 0.5-30mum. A photosensitive printing plate thus prepared is free from the vacuum adhesion to a slip sheet, since the back surface of the supporting body thereof is roughened.

Filed: 1985-03-04
Abstract: PURPOSE:To allow damping of dush pot without erroneous ignition or engine stoppage at the fastest speed possible by accelerarint damping speed when decline of engine rotation speed is judged to have come to an end. CONSTITUTION:At step 118, whether current engine rotation speed Ne is lower than memorized rotation speed NQR stored at step 112 or not is judged. When it is judged to be slower, the process goes ahead to step 120 since engine rotation speed Ne is declining, and after the current engine rotation speed Ne is reset at memorized rotation speed NQR, dush pot volume QREX derived at step 122 is damped at a normal rate. On the other hand, if current engine rotation speed Ne is judged at step 118 no to be less than memorized rotation speed NQR stored at step 112, dush pot is not required, and damping is carried out at steps 124 and 122, so that damping speed is twice as fast as the normal speed.

Abstract: PURPOSE:To make the area of a black spot or white spot (light absence) much less and improve the display quality of the element by employing such a columnar spacer that the width between the ends is narrower than the vertical width. CONSTITUTION:When the width of the upper or lower part in the section of the columnar spacer 12 is denoted as L1 and the width of the center part is denoted as L2, L2 may have any small value no matter how small it is on condition that strength which is large enough to hold the gap between substrates 11 and 41 uniform with necessary precision is obtained. Further, effect for light absence reduction is recognized when L2/L1<=0.95. Preferably, L2/L1<=0.8 so as to obtain remarkable effect. The part between the end and end, e.g. the center part of the columnar spacer 12 is recessed below the upper and lower ends to put a part where the orientation of liquid crystal at the peripheral part 12 of the columnar spacer 12 is disordered, specially, an area 44 where the disorder of liquid crystal orientation present at the cell center part expands most in the recessed part of the columnar spacer 12, so the spread of the part where the orientation is disordered can be suppressed.

Filed: 1986-02-28
Abstract: PURPOSE:To attain the operation at a high frequency without increasing number of pins for externally mounted components by constituting the titled circuit by a couple of NPN transistors (TR) to the bases of which oscillation signals are supplied in opposite phase to each other and a couple of NPN TRs whose emitters are connected in common. CONSTITUTION:Voltage signals generated across resistors R9, R10 respectively by the oscillation of an oscillation section are impressed to bases of TRs Q17, Q18.

In impressing a control voltage Vc in a direction increasing the base voltage of a TR Q22, the oscillated frequency of the oscillation section is controlled in the decreasing direction. Thus, through the constitution above, one pin P4 for an externally mounted component is enough, and since no PNP TR is employed, the operation at a high frequency is attained.
