Title: Liquid crystal display device with picture read function and picture read method
Inventor: OKADA TAKASHI
IPC: H04N5/378
Filed: 1998-04-20
Abstract: PROBLEM TO BE SOLVED: To provide a device where high read picture element density is obtained and manufacturing cost and power consumption can be reduced by providing plural back light sources emitting the light beams of different colors. SOLUTION: The back lights 18 are provided with single color light sources 18a-18c emitting red, blue or green single color light. The lighting and lighting- out of single color light sources 18a-18c are independently controlled by a control part. The red, blue and green single light sources 18a-18c are sequentially and selectively lighted and a display operation similar to a monochrome picture display device is executed based on red, blue or green display data in respective lighting periods. Namely, red, blue and green components are time-divisionally displayed for respective unit picture elements and the color picture is displayed by the after image effect of sight. Thus, one single picture element can be operated as the color picture element and the picture element density of the color picture element can be made equal to the picture element density of the single picture element.

Filed: 1979-08-29
Abstract: PURPOSE:To obtain the diode which has preferable reverse characteristics and low positive voltage drop by coating a P<+> type layer in island shape on an N type layer on an N<+> type layer and coating Pt thereon. CONSTITUTION:The islandlike P<+> type layer 4 is formed on the N type epitaxial layer 2 on the N<+> type layer 1, the Pt layer 8 is deposited thereon, and a Schottky junction is formed between the layer 8 and the layer 2. Ni electrodes 5, 6 are formed respectively on the layers 1 and 8. When a voltage is appleid between the electrodes 6 and 5 and a forward voltage is applied to the P-N junction 3, the forward current will flow in parallel with the P-N junction and the Schottky junction 7.

Title: Oscillation damping device
Inventor: NOZAKI TAKEAKI
IPC: B63B39/02
Filed: 1995-05-09
Abstract: PURPOSE: To enhance the oscillation damping effects of a device which damps the oscillation of a ship or other objects through the oscillation of a weight in a phase that is π/2 delayed with respect to the oscillation of the object by braking, if the phase of rotation of an oscillating link is advanced from the phase of oscillation of the object, a buffer member which damps the rotary movement of the link. CONSTITUTION: When a ship S oscillates crosswise, a link 1 equipped with a damper CL 1 is put into apparent oscillation by the inertia of a weight W1 in the opposite direction to the direction of oscillation of the ship S, but is oscillated with a little delay from the oscillation of the ship S since there is a restoring force caused by a spring 7. Then a movable gear 3 is rotated relative to a fixed gear 2 as the link 1 oscillates, so the weight W1 is rotated at increased speed in the same direction as the oscillation side of the link 1, and the inertial effect of the weight W1 is enhanced.  The support point P4 of the spring 7 is provided within a guide groove 8a in such a way as to be free to move vertically, and the position of the spring support point P4 is adjusted by control of a cylinder CL2 in accordance with outputs from a rotation angle sensor S1 and an oscillation angle sensor S2.

Filed: 1994-04-25
Abstract: PURPOSE:To precisely detect foreign matter on a photomask surface by providing an optical means, first and second detectors and a correcting means, and correcting the light quantity on the photomask surface. CONSTITUTION:A scattered light 48 is detected by an optical detector (first) 46 through a convergence optical system 47. A beam light 41 is reflected by a beam splitter 39, and made incident on an optical detector (second) 38. A correcting system 35 conducts factor correction to provide a precise foreign matter size. Namely, when the light quantity I38 of the beam 41 is large, the transmissivity of a pelicle 50 is small, the light quantity cast on the foreign matter 44 is small, and the scattered light 48 quantity is thus reduced. Since a dust of a fixed size is precisely judged to the light quantity I46 inputted to the detector 46, the function of changing slice level is imparted to the correcting system 35 to change the slice level according to the signal of an electric amplification processing system 37. The gain of an electric amplification processing system 36 for amplifying the signal obtained by the detector 46 according to the signal output of the light quantity I38 detected by the detector 38 is changed.
