Title: Phase locking system
Inventor: YAMAZAKI MASAMI
IPC: G11B20/14
Filed: 1981-12-12
Abstract: PURPOSE:To facilitate an adjustment of a phase locking circuit and to improve its handling range by bringing a selector for characteristic selection under the automatic control of a central processing unit. CONSTITUTION:One of terminals 18-28 for characteristic selection is selected by a selector 13 for phase locking characteristic selection. Actually, a magnetic recording device 12 is operated to read data and in this case, the terminal 18 is selected firstly by the selector 13. Normally, when reading operation is performed while the terminal 18 is selected, or when a readout error occurs, a CPU10 controls the selector 13, which selects the succeeding terminal 19 to retry the reading operation. Thus, every time an error occurs, a succeeding terminal is selected successively. Backward selection is also possible.

Title: Shutter mechanism for precise irradiation and control method
Inventor: MORITA HIROSHI
IPC: H01L21/268
Filed: 1999-07-14
Abstract: PROBLEM TO BE SOLVED: To provide a laser annealing device which allows uniform processings by irradiating of stable laser light on a work. SOLUTION: A laser light Al from a laser light source 10 is shielded appropriately with a shutter device 40, so that during the period of the initial laser oscillations where energy fluctuation is large, no laser light Al is incident on the surface of a work W. Thus, the laser light AL of stable energy is supplied to the surface of work W at a required timing. At the alignment of irradiation regions on the work W to an irradiation optical system 20, a process stage device 33 is operated in stepping manner, however normally during the stepping operation, no laser light AL is emitted to stop the oscillation of the laser light source 10. Thus, the unnecessary operations of the laser light source 10 is reduced in number to prevent power loss, while degradation of a device is being suppressed.

Abstract: PURPOSE: To reduce color irregularity on a projection screen caused in the case of synthesizing a video and to obtain the video whose uniformity is high by arranging a virtual plane formed by the optical axes of projecting lenses on two liquid crystal projecting machines so that the virtual plane may be in parallel with the short side direction of the projection screen. CONSTITUTION: The first liquid crystal projecting machine 10 and the second liquid crystal projecting machine 20 are arranged so that the optical axis 12 of the projecting lens may cross at a right angle with the optical axis 22 of the projecting lens and the virtual plane including the optical axes 12 and 22 may be in parallel with the short side direction of the projection screen. A half-wave plate 30 for rotating polarizing direction by 90 deg. is arranged between the lens 11 of the projecting machine 10 and a polarizing beam splitter 60. Since the virtual plane including the optical axes 12 and 22 is in parallel with the short side of the projection screen, the incident angle of the polarizing beam splitter 60 toward a polarized light synthesizing surface 61 is about 45 deg.±10.4 deg. so as to make the difference of an incident angle small.  As a result, the influence of incident angle dependency on the polarization beam splitter 60 can be reduced.

Abstract: PROBLEM TO BE SOLVED: To suppress the flow of a resist by a step when a resist is applied on side walls of a recessed part on a substrate by forming one or more steps on the side walls and specifying the width of the steps. SOLUTION: A silicon substrate 10 as photoelectronic parts is provided with a recessed part 12 to house optical fibers or the like.

Filed: 1982-11-16
Abstract: PURPOSE:To obtain the absolute value of the difference in refractive indexes between the inside of a core or the center of the core and a clad by very simple operation, by converging light from a light source or convergent light from a condenser lens by a plurality of pin holes having different diameters. CONSTITUTION:A condenser lens 5 has an NA (aperture), which is sufficiently larger than the maximum NA of an optical fiber 1. The condenser lens is arranged in such a way that parallel light from a light source is converged and a focal point is formed on the end surface of the optical fiber 1. At the light source side of the condenser lens 5, a stop plate 6 is arranged. In this case, the stop plate 6 is rotated, and the central axial line of a pin hole 6a, whose diameter is smallest, is made to agree with the optical axis of the condenser lens 5. Then the light from the light source is converged to the smallest area by the pin hole 6a and enters the condenser lens 5. Thus the absolute value of the difference in refractive indexes between a core or the center of the core and a clad can be obtained by a very simple operation.
