Title: Optical switch
Inventor: KOAKUTSU YASUMASA
IPC: G02B26/08
Filed: 1985-04-05
Abstract: PURPOSE:To form a small-size, simple optical switch by switching optical paths by utilizing the lens effect of a face plate, and reflecting projected light by a light reflector which contacts the face plate and switching the optical paths. CONSTITUTION:The face plate 3a and reflecting mirror 3b are arranged in one body between two couples of optical fibers 1a and 1b, and 2a and 2b having mutually opposite end surfaces. Those face plate 3a and reflecting mirrors 3b are moved up and down to project light signals of the optical fibers 1a and 2a from end surfaces of the optical fibers 1a and 2a and make them incident on end surfaces of the opposite optical fibers 1b and 2b when the face plate 3a face the end surfaces of the optical fibers 1a and 1b, and 2a and 2b. When the reflecting mirror 3b faces the end surfaces of the optical fibers 1a and 1b, and 2a and 2b, projected light beams are reflected by reflecting surfaces 31a and 31b, so that the light signal from the optical fiber 1a reaches the optical fiber and the light signal from the optical fiber 2a reaches the optical fiber 2b respectively.

Title: Manufacture of inorganic molding
Inventor: NOZAKI ZENJI
IPC: B28B7/34
Filed: 1998-03-19
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing an inorganic molding having no foam on its surface, having a mold face pattern transferred thereon with excellent reproducibility, and excellent in releasability. SOLUTION: In a method for manufacturing an inorganic molding by filling an inorganic composition having SiO2 -Al2 O3 , powder, alkali metal silicate, and water as principal components into a mold whose surface is formed of a synthetic resin or a rubber composition, a water-based wax thin film layer whose water content is set to 5-50 wt.% is formed along the mold surface, then the inorganic composition is filled into the mold. As a method for forming the water-based wax thin film layer, though there is no particular limitation, for example, brush coating, spray coating, and roller coating can be named. As for the coating quantity, 5-200 g/m<2> at solid content conversion is preferable. That is, when the coating quantity is smaller than 5 g/m<2> at solid content conversion, releasability lowers.  When the coating quantity exceeds 200 g/m<2> , the wax content fixes on the surface of the molding, thereby raising a fear of lowering of the hardness.

Title: Method and apparatus for measuring amount of optical displacement
Inventor: KOYAMA KATSUYA
IPC: G01B11/00
Filed: 1994-04-08
Abstract: PURPOSE:To provide a method for measuring the amount of optical displacement that is hard to be influenced by a disturbance light. CONSTITUTION:A light is emitted on a scale 90 that is provided with parts having different two optical characteristics which are periodically arranged one after the other so that a periodic image pattern is formed thereon. The periodic image pattern is detected by a one-dimensional image sensor 94, then the amount and the direction of relative displacement between the scale 90 and the image sensor 94 are judged from the variation of the periodic image pattern that is detected by the image sensor 94. The magnitudes of outputs of adjacent pixels of the image sensor are compared with each other so that a measurement pulse corresponding to the periodic image pattern is formed at a time point when the relationship of the magnitudes is inverted. The amount and direction of the relative displacement between the scale 90 and image sensor 94 are judged from the amount and the direction of movement of each unit of pixel of the image sensor 94 of the measurement pulse.

IPC: H04N5/91
Filed: 1983-04-22
Abstract: PURPOSE:To reproduce a magnetic tape recording a high speed phenomenon in a sufficiently low speed without causing disturbance of vertical synchronism and defect of picture. CONSTITUTION:Compressors CP-1-CP-5 being frequency converting means are inserted respectively between D/A converters DA-1-DA-5 and FM modulators MD-1-MD-5. The line scanning speed of analog image pickup signals VID-1-VID-5 obtained from the D/A converters DA-1-DA-5, i.e., only the horizontal frequency is compressed respectively into a multiple of (1+20/525) by using the compressors CP1-1-CP-5. Further, the carrier frequency of the FM modulators MD-1-MD-5 is selected to a multiple of 5(1+20/525) to the standard value. Moreover, rotary magnetic heads HA-HE are revolved at the standard number of revolutions and the magentic tape is run at a speed being 5 times the standard speed. Thus, the vertical blanking period of an image pickup signal of each field recorded on the magnetic tape is prolonged by 10H's share in this way.

Abstract: PURPOSE:To obtain the conducting copper alloy fiber having good conductivity and free from the deterioration of electromagnetic wave shielding properties in injection molded goods even if used for a long period of time at low cost by forming the copper alloy with the compsn. contg. specified amounts of Sn and P. CONSTITUTION:The copper alloy fiber contains, by weight, 0.1 to 10% Sn, <=0.5% P and the balance Cu. The copper alloy fiber is blended with thermoplastic resin and injection molding is executed, by which conductive injection molded goods can be manufactured by the conventional manufacturing process. In the fiber, Sn increases the electromagnetic wave shielding properties of the injection molded goods and prevents the deterioration of the above properties when used for a long period of time, but for the lower limit or less, the effect is insufficient, and for the upper limit or more, working into the shape of fiber of about <=0.1mmphi is difficult while the effect of improving the above properties is saturated as well. Furthermore, P moreover increases the effect of improving the above properties by Sn, improves the yield when Sn is added as its deoxidizer and effectively works on the prolonged stability of the above properties, but for the upper limit or more, working into the shape of fiber of about <=0.1mmphi is made difficult.

Abstract: PURPOSE: To attain color reproduction without occurrence of an unnatural contour and reducing the conversion precision by applying 3-dimension smoothing filter processing to a table generated based on color chart data and used to convert an RGB signal into a CMY signal so as to generate a lookup table. CONSTITUTION: A table used to convert an RGB signal into a CMY signal is generated based on color chart data obtained by using an image reader so as to read a color chart outputted from an image output device. A 3-dimension smoothing filter processing is applied to the table used to convert an RGB signal into a CMY signal to generate a lookup table. A filter 303 making up of three stages of filters connected overlappingly is employed for the 3-dimension smoothing filter processing. The filter size of the filter 303 is 3×3×3 and the filter 303 applies smoothing processing to color correction data of a grating point 310 of 9×9×9. Thus, continuous gradation is reproduced even in the presence of dispersion or the like in process conditions.
