Title: Automatic focus controller
Inventor: SHIBATA ITARU
IPC: G02B7/28
Filed: 1982-09-30
Abstract: PURPOSE:To execute good focus control by setting a level of a focus shift signal at the point of time when a reproducing information signal becomes maximum, to a target value of a focus servo-loop, and closing the servo-loop, in an optical disk device which focuses an optical beam to a discoid recording medium and records and reproduces information. CONSTITUTION:When an objective lens and a disk medium face enter into some range, a focus shift signal (b) is obtained, and when the best focus state, namely, a disk medium face 4 comes to a focal position of the objective lens, a reproducing information signal (c) indicates a peak value. Therefore, a level of the focus shift signal (b) in this case is held, and a focus servo-loop is closed by setting said level to a target value. Also, in this case, a signal (a) of a triangle wave applied to the objective lens sero-system is detached from the objective lens servo-system. That is to say, when a peak of a reproducing information signal (c) is detected by a peak detetor 12, a switch SW1 is closed by switching a switching signal to H from L, and the focus shift signal (b) in this case is held. A switch SW2 selects a focus control signal (e).

Title: Vibration reduction device for vehicles
Inventor: UCHIDA HIROSHI
IPC: B60R11/02
Filed: 1993-06-18
Abstract: PURPOSE:To optimize the vibration for reduction in units of 1 period, i.e., to enhance the effect of the reduction of vibration when the period is changed. CONSTITUTION:The periodic first vibration generated due to the rotation of an engine 8 is reduced by the interference action of the second vibration (vibration for reduction) outputted from a loudspeaker 11 installed in a cabin 2. The second vibration is set in units of 1 period of the first vibration, and the vibration energy of the second vibration is corrected in accordance with a signal from a microphone 12 for detecting a vibration in the cabin 2 and the transfer characteristics between the microphone 12 and the loundspeaker 11. If the phase of the second vibration deviates from an adequate value due to the fluctuation of the rotation period of the engine 8, the phase of the second vibration is adjusted so as to compensate the deviation of the phase. The adjustment of the phase is executed in accordance with the dominant order-component by which the noise level is made higher, e.g. in accordance with the 6th component in the low rotation region and the 3rd component in the high rotation region when the engine 8 is of V type 6-cylinder.

Filed: 1981-10-28
Abstract: PURPOSE:To obtain a reader with extremely high reading resolving power, by arranging poly Si having photoelectric effect in an array and providing electrodes by pinching each film. CONSTITUTION:The poly Si film 3 in approx. 5,000Angstrom -3mum is evaporated on a ceramic substrate 1 so as to lie over the pairs of electrodes 2A, 2B, and both ends of the electrode are forced out of both sides of the film 3 and covered with transparent protection film according to necessity. The film 3 is divided into a many film sections 3A consisting of units of regions each between the electrode 2A and 2B, and, when some of the film sections 3 are irradiated, the resistance value of the film 3A section greatly decreases. When a voltage is kept  impressed across the film 3A, a photocurrent flows between the electrodes 2A,  2B on both sides of the film. The photocurrent is read by moving the array of  the film 3A in a direction at right angle with the array and scanning it on the surface to be irradiated. The film 3A is formed in approx. 12mum and the reading resolving power can be extremely enhanced. Besides, when a long converging lens is provided on the surface, and each film 3A is projected, the sensitivity  can be improved.

Title: Method for measuring tilt angle of liquid crystal molecule
Inventor: NISHINO TOSHIHARU
IPC: G02F1/13
Filed: 1991-07-12
Abstract: PURPOSE:To measure the tilt angle of the liquid crystal molecule of the twist arrangement liquid crystal cell to be measured between a pair of substrates by arranging a photoelastic modulator and detecting the intensity of transmitted beam while the liquid crystal cell to be measured is rotated around an optical axis. CONSTITUTION:A photoelastic modulator 14 is arranged between a polarizer 13 and a liquid crystal cell 20 and the cell 20 is rotated around an optical axis O. The output beam of laser 11 passes through the polarizer 13 to become linear polarized beam which is, in turn, modulated in its polarized state corresponding to modulation frequency by the modulator 14 to enter the cell 20. This beam is further changed in its polarized state by the double refraction property of a liquid crystal 24 during the transmission through the cell 20 to enter a photodetector 12 through an analyser 15. The photodetector 12 detects the intensity of the beam to output the signal corresponding to said intensity to an operation part 17. The operation part 17 calculates the apparent double refraction property of the liquid crystal from the intensity of the transmitted beam and calculates the tilt angle of the liquid crystal molecule of the twist arrangement liquid crystall cell from the calculated value and known values, that is, the thickness of the liquid crystal layer, the twist angle of the liquid crystal molecule and the abnormal and normal beam refractive indexes of the liquid crystal.

Abstract: PURPOSE:To realize high brightness and low power consumption by effectively utilizing the light of a back light. CONSTITUTION:A microlens array 5 is a polymer molding united with a substrate 2. Namely, the transmission type dot matrix liquid crystal display device which has the back light 3 on the back surface uses a polymer film for a substrate 2 at least on the side of the back light 3 and also uses the microlens array united with the substrate 2 corresponding to display dots on the surface of the polymer film substrate on the side of the back light 3.
