Title: Production of hologram color filter
Inventor: MIYAJI YOSHIYUKI
IPC: G02F1/1335
Filed: 1995-08-28
Abstract: PROBLEM TO BE SOLVED: To decrease the unnecessary interference fringes occurring due to unnecessary reflection, etc., between both surfaces of an original plate hologram and between the original plate hologram and a hologram photosensitive material at the time of producing a hologram color filter by duplication. SOLUTION: The hologram color filter is produced by superposing the hologram photosensitive material 8 on the relief type computer hologram original plate 7 and making a laser beam 9 incident thereon from an original plate 7 side, thereby duplicating the hologram. In such a case, a wedge-shaped transparent member 15 is superposed on the incident side of the original plate 7 to make the incident side surface of the original plate 7 and the exit side surface thereof non-parallel with each other, thereby, the light (2) reflected by the incident side surface of the transparent member 15 and the light (1) advancing rectlinearly in the hologram original plate 7 are non-paralleled. Even if both light rays interfere with each other on the photosensitive layer 13, the interference fringes of a relatively narrow spacing are formed.  These interference fringes are obscure even if these fringes overlap on the displayed images. The degradation in the display quality is thus prevented.

Filed: 1997-08-13
Abstract: PROBLEM TO BE SOLVED: To provide a tracking control apparatus and method based on a 1-beam method which enables adaptively setting of the optimum servo coefficient for each optical disc. SOLUTION: A difference (E-F) between signals E and F and a sum (E+F) thereof from terminals 11 and 12 are found by an subtraction amplifier 13 and an addition amplifier 14 to find a standardized push/pull signal NPP =(E-≠)/(E+F) with a division circuit 20. The amplitude of the signal is detected by a signal amplitude detection circuit 30 and sent to a coefficient calculation circuit 50 through an A/D conversion circuit 40 to set a tracking servo coefficient K according to the amplitude of the NPP signal. A moving value signal CSL of an objective lens generated by top hold circuits 65 and 66 and a subtraction amplifier 70 is multiplied by the coefficient K using a multiplication amplifier 80 to make a cancel signal, which is subtracted from a pushpull signal PP by a subtraction amplifier 99. Thus, the offset of the signal PP is cancelled to obtain the optimum tracking error.

Title: Defect inspecting device
Inventor: DOI HIDEAKI
IPC: G01B11/30
Filed: 1985-10-03
Abstract: PURPOSE:To enable the easy discrimination of a defect and a foreign matter on a surface of an object to be inspected, by integrating a slant illumination microscope with a part of a phase microscope to compare two images of the object being inspected. CONSTITUTION:An illumination light of a light source 10 of a phase microscope lights an object 14 to be inspected via a filter 30 and a direct light 37 passing therethrough is attenuated and made interferable with a diffraction light 38 by a phase plate 16 to serve as a back ground light at a detection image of an image field 36. Illumination light 39 of a slant microscope forms an image on the image field 36 via a filter 33 which transmits a light with the wavelength differing from the filter 30. A foreign matter on the object 14 being inspected can be discriminated by comparing the two images. When both the images are detected, a foreign matter is identified and a defect is identified when the image alone with the phase microscope is detected. This enables the detection of a defect such as fine ruggedness and changes in refractive index on an object being inspected at a high accuracy.

Title: Driver for synchronous motor
Inventor: HASHIMOTO KAZUSHIGE
IPC: H02K7/118
Filed: 1995-08-04
Abstract: PROBLEM TO BE SOLVED: To prevent abnormal abrasion of a friction clutch by a structure wherein first and second rotators frictionally transmit the rotation of a rotor only in a predetermined direction and rotate integrally in case of reverse rota tion. SOLUTION: When a rotor 6 rotates in a predetermined direction, a first rotator 13 rotates in a predetermined direction. The rotation is transmitted through one way frictional rotation transmission mechanisms 14, 15, 16a to a second rotator 16 which is thereby rotated under no-load during a first idle interval. In this regard, the one way frictional rotation transmission mechanisms 14, 15, 16a do not rotate integrally but rotate frictionally and the second rotator 16 rotates, while sliding, in a predetermined direction with a lag behind the first rotator 13. This state is sustained until the rotor 6 is coupled with the second rotator 16. After being coupled with the second rotator 16, the rotor 6 sustains synchronous rotation.
