Abstract: PROBLEM TO BE SOLVED: To prevent an object lens from touching an optical disc when the optical disc is warped by its own weight at the focus searching operation, etc. SOLUTION: If the focus locking-off are detected by a focus locking-off detection unit 22, the output of a downward lens transfer unit 25 is inputted to a focus driving amplifier 27 and an object lens is transferred to a position apart from an optical disc 40. Further, a tracking servo is released and the output of an inward sled transfer unit 30 is inputted to a sled driving amplifier 32 and an optical pickup 10 is transferred to the innermost circumference of the optical disc 40. At that position, the focus search is performed by a focus searching unit 24 and the focusing servo is applied by a focus feedback unit 23. Then the optical pickup 10 is transferred to the original tracking position by a sled servo unit 29 and the tracking is applied by a tracking servo unit 33.

Title: Detector for displacement
Inventor: SHIOZU HIROO
IPC: G01L9/04
Filed: 1984-06-15
Abstract: PURPOSE:To detect displacement by strain only in the direction of pull with high accuracy by fixing two OMEGA-shaped elastic plates, to which resistors for strain gages are fastened and which have different shapes, to a pedestal. CONSTITUTION:The ratio of the sensitivity of strain of the direction of pull to the direction of bending is increased extremely in order to easily compensate a detecting value by strain in the direction of bending regarding the OMEGA-shaped forms of an elastic plate 1 and a second elastic plate 4. A resistor 2a and a resistor 5a as strain gages are stuck to each curved surface section of the elastic plate 1 and the second elastic plate 4. Only a strain value of either of the direction of pull, the direction of compression or the direction of bending is detected by arithmetically operating a synthetic detecting value obtained from outputs from the strain gages.

IPC: G11B7/24079
Filed: 1991-04-24
Abstract: PURPOSE:To prevent double transfer by providing intermittent grooves disposed with mirror parts synchronized with sample marks at 0.25 to 0.75mm width on the inner and outer sides of a track region. CONSTITUTION:The groove regions 4, 5 formed with the mirror parts 3 of microsections respectively on the inner and outer peripheries are provided in proximity to the track region in correspondence to the sample marks 2. The groove regions 4, 5 are so formed as to be discontinuous with the mirror parts 3 of the microsections in-between and, therefore, the deviation in the sample marks by the molten resin material injected into metallic molds is supported by the groove regions 4, 5 and the double transfer is prevented. The gases generated from the resin material are simultaneously discharged smoothly along the sample marks 2 by passing the mirror parts constituted of the intermittent grooves. Since the track region is not affected by these gases, the resin packing rate is increased.

Abstract: PROBLEM TO BE SOLVED: To improve the joint efficiency with the propagated light from an optical fiber and the joining efficiency to a directly joined counter part element by forming a specific number or above of core layers on at least one of waveguide regions. SOLUTION: The waveguide regions A1, A2 varying in band gap from each other are formed to a butt joint structure directly connected with the each other's waveguides 2, 3 at a 5 juncture AO on a common substrate 1. An upper clad layer 4 is formed thereon. Two or more layers of the core layers are formed on at least either of the waveguide regions A1, A2. The structure in which spacer layers function as the clad layers between the respective divided core layers is adopted. The thickness as the effective core layers is increased and the coupling efficiency between both when the optical fiber of single mode is connected is improved by adopting such laminated structure. While the number of the layers of the divided core layers is not particularly limited, the number of the layers is determined by the relation with the thickness over the entire part of the core layers.  The upper limit of the thickness over the entire part of the core layers is set approximately at 1.5 μm.

Title: Liquid crystal panel and liquid crystal projection type television using the panel
Inventor: TAKAHARA HIROSHI
IPC: G02F1/1333
Filed: 1992-05-15
Abstract: PURPOSE:To provide the liquid crystal panel of a high brightness and high contrast display. CONSTITUTION:A thin film 17 is formed of a material having the specific dielectric constant lower than the specific dielectric constant of high-polymer dispersed liquid crystals 15 on a counter electrode 13. The refractive index of the thin film 17 is made to coincide approximately with the ordinary ray refractive index no of the liquid crystals. A refractive index difference  n is generated between the polymers and water-drop-like liquid crystals in the liquid crystal layer 15 and the incident light is scattered when a voltage is not impressed to the liquid crystal layer 15. The liquid crystal molecules orient and the refractive index of the liquid crystal layer turns to the ordinary ray refractive index no when several V or higher voltage is impressed to the liquid crystal layer. The incident light, then, advances rectilinearly and is emitted from picture element electrodes 14. Electric lines of force are generated within the liquid crystal layer 15 when 5 to 3V voltage is impressed to the liquid crystal layer 15, but the dielectric constant of the thin film 17 is low and, therefore, the electric lines of force bend near the thin film 17. The liquid crystal molecules orient along the electric lines of force if the electric lines of force have the prescribed intensity or above. The liquid crystal molecules orienting in the horizontal direction of the substrate 11 increase and the refractive index of the liquid crystals 15 increases and the  n increases as well if the electric lines of force bend. Then, the scattering performance is improved.
