Inventor: KOSHIO YOSHIHIRO
IPC: G09F9/00
Filed: 1997-04-30
Abstract: PROBLEM TO BE SOLVED: To accurately detect the position of the both transparent substrates, which constitute of a liquid crystal panel, by clearly imaging plural alignment marks formed on the top and the bottom transparent substrates employing a single imaging unit. SOLUTION: A position detecting means 22 detects alignment marks 7 formed on the surfaces, which facing to each other, of top and bottom transparent substrates 2 and 3 of a liquid crystal panel 1 mounted on a positioning table. The means 22 has a lighting unit 30 and an imaging unit 31. The unit 31 images the marks 7 from the top of a liquid crystal panel 1. An objective lens 35 of the unit 31 is focused on the mark 7 provided on the bottom side transparent substrate 3. In order to image the alignment mark of the top side transparent substrate 2, a transparent glass 38 is freely inserted and taken out into and from an optical path at the position of the object side of the lens 35 of a housing 34 so as to compensate for the deviation in the focusing caused by the refractive index of the substrate 2.

Title: Optical scanner
Inventor: MINOURA KAZUO
IPC: H04N1/113
Filed: 1982-07-17
Abstract: PURPOSE:To eliminate the uneven pitch in scanning lines and to obtain an image having good quality by detecting a moving speed from the code signal provided on the surface of a medium to be scanned or a moving member for the same, and controlling the luminous flux from a deflection member to the auxiliary scanning direction. CONSTITUTION:A speed detector 9 consists of a light source 11 for detection for illuminating the bar code array 8 recorded in the end part of a medium 7 to be scanned with a lens system 10 and a photoelectric transducer 13 for detecting the light reflected from the array 8 with a lens system 12. When a change arises in the peripheral speed of the medium 7, a signal is outputted from the detector 9 at the time intervals corresponding to the change. A control circuit 15 for driving operates to drive a deflection member 3 so as to move the luminous flux L in a D1 direction. Even if the position of the luminous flux A on the surface of the medium 7 displaces according to the plane moving speed of the medium 7, the uneven space between the scanning lines A is corrected.

Filed: 1998-05-07
Abstract: PROBLEM TO BE SOLVED: To perform a seek operation or the like with high accuracy by generating a relative volocity signal of a light spot and a track from the product of a detected signal and a direction signal and driving an optical pickup using this product. SOLUTION: A seek servo performs a speed servo wherein the square root signal (S) of count values posterior to the calculation of a square root is defined as a target value, which is followed by a relative speed (P). When a following value reaches the target value, a number to target track-counter 50 informs a system controller 53 of the completion of a seek and switches 54, 55 are connected to third terminals by a mode changeover signal (W) from the controller 53. At these positions, a servo control is applied so as to make the relative speed zero and a braking acts strongly to drive an actuator. Then, the drawing of a high speed servo whose relative speed is sufficiently low and constant is performed by returning the switches 54, 55 with the mode changeover signal (W) from the controller 50 again a fixed time later.

Abstract: PURPOSE:To freely control a degree of hydrophile property with a excellent reproducibility by a method wherein a semiconductor substrate is soaked in a treatment solution of an organic solvent in which organic silane compound is dissolved at a fixed rate and an absorbent reaction of the compound is generated when a hydrophilic treatment is performed on the surface of an SiO2 film of the semiconductor substrate. CONSTITUTION:An SiO2 film 2 is coated on a semiconductor substrate 1, it is boiled using a mixed solution such as H2SO4 and H2O2 or the like and the impurities such as heavy metal molecules, Na molecules, etc., adhered on the surface of the film 2 are removed. But, when the above process is performed, the hydrophile property on the surface of the film 2 becomes too large, thereby generating troubles when a pattern is formed on said film. Therefore, the substrate 1 is soaked in a  treatment solution consisting of one organic solvent among butyle acetate, trichlene and methanol with a fixed amount of dissolved hexamethylene disilazane, and a desired value is obtained for a surface contact angle of the solution against the film. After that, an opening 4 having the desired taper angle delta can be obtained in accordance with the selected kind of solvent by performing an etching on the film 2 using a resist film 3 as a mask.
