Title: Drawing method of optical fiber
Inventor: NAKAHARA MOTOHIRO
IPC: G02B6/00
Filed: 1983-02-08
Abstract: PURPOSE:To cool efficiently an optical fiber by covering the surface of a capstan which draws out the optical fiber with a refrigerant liquid and drawing out the optical fiber via the film surface of the refrigerant liquid. CONSTITUTION:A base material 7 for an optical fiber is heated to about 2,100- 2,200 deg.C to soften the same with a heating element 1, and while the diameter thereof is measured without contacting with a device 8 for measuring the outside diameter of the fiber, the optical fiber 2 is introduced into a take-up part consisting of a capstan 7. A refrigerant liquid 9 is then ejected from a nozzle 10 in parallel with the traveling direction of the fiber 2 to fill the gap between the fiber 2 and a capstan 4 by following up the traveling speed of the fiber 2. The direct contact of the fiber 2 and the capstan 4 is thus prevented by the liquid 9 and the cooling of the fiber 2 is made possible without damage on the surface thereof. A plastic material is then coated on the fiber by a coating jig 8 of a horizontal type without inducing the thermal deterioration of said material, and the coated fiber is taken up on a drum 6.

Filed: 1987-01-29
Abstract: PURPOSE:To improve the yield of the title filter by hot-pressing a transparent colored photosensitive resin layer formed by a casting method on a substrate, and patterning the layer to eliminate the process wherein the photosensitive resin is directly coated on the substrate. CONSTITUTION:The transparent colored photosensitive resin layer 2 is formed on a base film 1 by a casting method, etc., a protective film 4 is formed thereon, and the film is wound. The protective film 4 is released, and the layer 2 is hot-pressed on the substrate 5 along with the base film 1. The layer 2 is subsequently exposed through a photomask 6, the base film 1 is released, and development is applied to form a transparent colored picture image pattern 8. The process is repeated, and transparent colored picture image patterns having different hues are formed. A transparent dyeable photosensitive resin layer is used instead of the transparent colored photosensitive resin 2 to dye the picture image patterns, and a transparent colored picture image pattern can also be formed.

Title: Oxygen concentration sensor with heater
Inventor: IKEGAMI SATOKO
IPC: G01N27/409
Filed: 1993-02-08
Abstract: PURPOSE:To enable the preventing of matters adhered from turning amorphous to cover the surface of a sensor with a vitreous material by cooling the sensor gradually after the stoppage of an internal combustion engine. CONSTITUTION:Signal lines 42 and 43 are so arranged to supply a potential difference to an electronic controller 30 according to a difference of the concentration of oxygen between internal and external spaces of a sensor element 31. An atmosphere in an exhaust manifold is introduced into the external space of the element 31 and the atmospheric air into the internal space. A ceramic heater 44 is energized through heater wires 45 and 46 to generate heat and heats the element 31. Various substances contained in an exhaust gas adhere to the surface of the element 31. When the substance adhered is cooled rapidly, it turns amorphous, namely, vitreous so that no oxygen molecule can reach the surface of the element 31. When the substance adhered is cooled gradually, it is crystallized to be porous allowing the passage of the oxygen molecules. So, after an internal combustion engine shifts to stoppage, the heater 44 is controlled with controller 30 to cool the element 31 gradually thereby achieving a heating control of the sensor 16.

Title: Diversity receiver
Inventor: KAWAMOTO NORIYUKI
IPC: H04B1/10
Filed: 1981-02-13
Abstract: PURPOSE:To eliminate the influence of a switching noise, etc., by reducing the frequency of the unnecessary switching of antennas, by lowering the switching sensitivity of the antennas in a weak electric field or intense electric field. CONSTITUTION:The output of a comparing circuit 16 is passed through a frequency-voltage converting circuit 17 having prescribed characteristics to give a reference voltage E's to the reference voltage source 14' of a comparing circuit 12. Consequently, when antennas 1 and 2 have enough sensitivity or when an enough SN ratio can not be secured in a weak electric field area, the reference voltae E's is applied from the circuit 16 via the circuit 17 to the circuit 12. Therefore, the reference voltage is high, so the circuit 12 becomes hard to operate. As a result, the frequency of the switching of the antennas is reduced through an  FF13 and linkage switching noises are reduced. Further, the frequency of the circuit 16 is reduced where the electric field is intense and a high SN ratio is secured, so the circuit 17 applies the low reference voltage E's to the circuit 12, so that a reception system operates as a high SN ratio system.

IPC: G01B11/08
Filed: 1992-02-06
Abstract: PURPOSE:To omit a grain size filter and to make the speed of measurement high by extracting the data corresponding to the diameters of the particles among the number of pixels obtained based on the binary-coded image data and the data on the number of particles. CONSTITUTION:The images or the projections of grains with a CCD camera 21 are binary-coded. The binary-coded image data are stored in a storage device 12. The number of continuous white pixels is measured with an operating device 23 for the scanning lines of the powder images from the highest level to the lowest level so as to obtain statistics. A circle, wherein the maximum number of pixels among one set of the binary-coded data is made to be a diameter, is obtained. The data of the numbers of pixels in the circle are subtracted from the statistic values obtained beforehand, and correction is performed. Thus, the data contained in the statistic value are only the data corresponding to the diameter of that particle. In this way, the operation from the longest data to the shortest data of the binary coded images of all particles is repeated, and the grain-size distribution curve for all the particles is obtained.
