Title: Digital rotating phase servo device
Inventor: TABUCHI JUNICHIRO
IPC: G05B13/02
Filed: 1991-06-20
Abstract: PURPOSE:To provide a high-order lag-lend tipe filter used as a phase compensating filter with simple configuration by serially connecting and inserting plural first-order lag-lead filters in a phase servo loop. CONSTITUTION:First-order lag-lend type filters 31 and 32 are serially connected and inserted in the phase servo loop in place of second-order lag-lead filters. In order to constitute this connection with the software of a microcomputer, it is executed twice with the first-order lag-lead filters 31 and 32 as sub routines. In order to obtaining a desired phase compensating characteristic, in the case of executing the sub routine twice, coefficients K6-K8 of coefficient multipliers 43-45 can be made equal or different in the two times of execution. Delay time is made equal for delay equipments 41 and 42 in the two times of execution for executing the same sub routine, and the poles of the two first-order lag-lead filters are made completely coincident. Thus, neither oscillation due to deterioration in servo characteristic nor deterioration in performance of the high-order lag-lead filter is caused.

Title: Device and method for texture mapping
Inventor: TAKEMOTO TAKU
IPC: G06T15/00
Filed: 1999-05-27
Abstract: PROBLEM TO BE SOLVED: To execute inexpensive texture mapping of high quality by generating an LOD value with simple hardware. SOLUTION: When a point on a screen plane is moved by a small distance in a direction parallel to a cross line that a plane containing a polygon being the object of texture mapping and a screen plane make in an eye coordinate system (X, Y and Z), the logarithm of a ratio between the distance and a distance where a point on the texture plane, which corresponds to the point, moves is set to be an LOD value λ. Thus, a liner interpolation value generator 3 generates f1 (x, y) corresponding to the coordinate (x, y) generated by a pixel coordinate generator 1 and a logarithm unit 4 generates the logarithm log2  f1 (x, y)} of f1 (x,y). A subracter 6 can obtain λ by subtracting log2  f1 (x, y)} from log2 (k/Qz) preserved in a register 5. The logarithm is taken once and subtraction can be executed once and therefore λ can be obtained.  Thus, λcan be generated with simple hardware and the texture mapping of high quality can inexpensively be executed.

Abstract: PROBLEM TO BE SOLVED: To thin a base chassis and surely fix the base chassis without deforming the base chassis by forming the base chassis of a sheet metal. SOLUTION: A mount element 14 having a plurality of mount holes 15 is formed bending to a base chassis 5 of a sheet metal which holds a motor and an optical pickup. A plurality of mount stages 17 are provided on a supporting member 2, each having a bearing surface 20 on which a circumferential edge of the mount hole 15 of the mount element 14 butts, a first stepped projection 21 and a second stepped projection 22. A fitting screw 16 is clamped to the mount stage 17, thereby compressing an elastic washer 19 and fixing the mount element 14 to the bearing surface 20. In this case, a projection height (d) of the second stepped projection 22 is set to be smaller than a sum (b) of a thickness (a) of the mount element 14 and a thickness of the elastic washer.  Accordingly, even if a clamping force of the screw 16 is too strong, the base chassis 5 is prevented from being deformed and can be surely fixed to the supporting member 2.

Abstract: PURPOSE: To change much ultraviolet rays into visible rays and raise the luminous efficiency, by  gradually increasing the thickness of coating film of fluorescent substance on the reflector part of  a bulb for a reflection-type lamp toward the rear of the bulb when the coating film is electrostatically painted on the inside surface of the bulb.   
     CONSTITUTION: The outer bulb 1 for the reflection-type high voltage mercury lamp is put in a  heating furnace 8 so that the light-penetrated front part 2 of the bulb is heated at a temperature of  50 to 100°C and the reflector part of the bulb is heated at a temperature above 100°C. A sprayer  10 is inserted into the bulb. The grounded anode of an electrostatic power source 7 is connected  to the bulb 1. The cathode of the power source 7 is connected to discharge electrodes 12a, 12b on  a fluorescent substance powder projecting pipe 11. The position of the sprayer is lowered in the  bulb. Corona discharge is caused between the discharge electrodes 12a, 12b to charge the fluorescent substance ejected. Thereby, the fluorescent substance is electrostatically painted on the inside  surface of the bulb. Sine the temperature of the reflector part 3 is high and the position of the  sprayer 10 is low, the thickness of the coating film of the fluorescent substance is large on the  neck part 5 of the bulb but small on the light-penetrated part 2 and on the boundary between the  neck part and the light-penetrated part. Much ultraviolet rays are changed into visible rays by the  thick part of the coating film. Thereby, the luminous efficiency is enhanced.

Abstract: PURPOSE: To prevent lowering of a service life due to high temperature of a punch by directly spraying a lubricant on the part of the punch that is under thermal effect and thereby cooling the punch. CONSTITUTION: A heated material 10 to be worked is set between a centering die 6 and a punching die 7 while a slidingly lowered punch 1a, or 1b punches out the slug of the material in the hot region. The route of a cooling medium is preliminarily selected depending on the diameter of the slug of the material and, if the punch 1a with a large diameter is used, the flowing route of the cooling medium is secured from inside, so that the cooling medium is discharged to the side of the punch. If the punch 1b with a small diameter is used, the cooling medium is ejected intensively on the punch standing by at the top dead point after the slug of the material is punched out, from the outlet in the inner diameter part of a stripper plate 2.

Title: Automatic take-up tension adjusting mechanism of magnetic tapes
Inventor: MINAMI SHIGEO
IPC: G11B15/43
Filed: 1977-12-14
Abstract: PURPOSE: To accurately adjust the tension of magnetic tape by sensing the winding diameter of the mganetic tape in a reel with a sensor and actuating the tape column side wall according to the shange quantity of output thereby increasing or decreasing the pressure receiving area in the vacuum column.  
     CONSTITUTION: The winding diameter of a tape 2 is detected from the back pressure of the pressure being supplied to a sensor by the sensor 8 provided in opposition to the reel width of a tape reel 4, by which the change in the tape take-up diameter is detected as a change in back pessure value. This pressure is transmitted to the driving mechanism 11 of tape column side walls 9 through the pipe being a connecting mechanism 10. In the driving mechanism, the piston 12 coupled to one end of a spring being a comparator 13 moves as much as the change quantity of the pressure and is advanced or retreated to the position where the pressure and spring balance again and therefore the right side tape column side wall 9 moves to the right or left in parallel to the left side tape column side wall 15. As a result, the pressure receiving area on the tape 2 by a pump 7 changes and therefore the tension of the tape may be accurately adjusted.
