Title: Drive device and constant-speed movement servo method
Inventor: MITANI AKIRA
IPC: G11B21/08
Filed: 1998-10-09
Abstract: PROBLEM TO BE SOLVED: To provide the constant-speed servo method which is stable. SOLUTION: The best servo parameter is calculated (operation 1) from the state when constant-speed movement is performed by using an initial servo parameter as a certain fixed value and constant-speed servo is performed by using the calculated servo parameter to actualize a constant-speed travel (operation 4). Consequently, the constant-speed movement at certain speeds in a specific speed range is stably actualized irrelevantly to conditions such as characteristics and attitude state of the solid body of a recording and reproducing device.

Filed: 1988-11-16
Abstract: PURPOSE:To prevent the distortion of a sink chip level by lowering the demodulation efficiency of an FM demodulating circuit in response to the detecting output of a dropout detecting (DOC) circuit. CONSTITUTION:A demodulation curve is made smooth only during a noise period and the amplitude of a noise is relatively lowered. Thus, a noise generation period is detected by a DOC circuit 8. Namely, when a luminance signal to include the noise period to be a noise bar is impressed, the DOC circuit 8 generates the detecting output in response to the impression and the values of a variable current source 9 and a variable resistor are controlled in a direction, in which the values go to be small, in response the detecting output. In such a case, the characteristic of the demodulation curve is simultaneously adjusted by both axes. Thus, the noise to be generated at the time of VTR reproducing is reduced and the sink chip distortion of a reproducing luminance signal can be prevented.

Filed: 1997-10-23
Abstract: PROBLEM TO BE SOLVED: To eliminate the change of the thickness of a phase inversion layer so that the partial change of phase is eliminated by forming the surfaces of a light shielding layer and a base plate so that they are the same. SOLUTION: The light shielding layer 12 is formed inside a trench formed on the translucent base plate 10. At that time, the surface of the layer 12 is the same surface as that of the base plate 10.

Both end parts of the layer 14 are overlapped on the layer 12. Thus, since the surface of the layer 12 is formed to be the same as the surface of the base plate 10, the layer 14 is formed to have uniform thickness, and the error of the phase inversion of light passing through the layer 14 hardly occurs. Therefore, accurate transfer can be possible, and the reliable phase inversion mask can be obtained.

Title: Tubular resin molding and molding method thereof
Inventor: UZUNO YOSHINOBU
IPC: B29K101/12
Filed: 1995-11-09
Abstract: PROBLEM TO BE SOLVED: To prevent or reduce heat shrinkage of a resin material in a circumferential direction when the resin material which contains reinforcing fibers such as glass fibers is molded into a tubular shape by blow molding, by orienting the reinforcing fibers added to the resin material along the circumferential direction of a tubular molding. SOLUTION: In a resin product 4 molded by blow molding, all glass fibers 6 are oriented along the circumferential direction. In this case, as each glass fiber 6 displays an opposing force against a force to shrink, heat shrinkage of the resin product 4 in the circumferential direction hardly generates even under an atmosphere of high temperature, so that the inner diameter of the resin product 4 is not changed by heat shrinkage. Accordingly, a blow molding can be used also at a part where using of it has been difficult in fear of dimensional change due to heat shrinkage, thereby widening the scope of application of resin products.
