Title: Method for desulfurizing coat gas and apparatus therefor
Inventor: HANAYAMA FUMIHIKO
IPC: C10J3/46
Filed: 1988-04-25
Abstract: PURPOSE:To readily recover an unreacted desulfurizing agent, simultaneously reduce amounts of the desulfurizing agent and waste desulfurizing agent and facilitate solidification treatment of slag, by dividing powder contained in desulfurized coal gas, successively collecting and separating powder starting from a group having a large grain diameter. CONSTITUTION:A powdery desulfurizing agent (e.g., CaO) is fed to treat coal gas produced in a jetting stream bed coal gasification oven and powder contained in the resultant desulfurized coal gas is divided into groups in at least 3 stages for each grain diameter and then successively collected and separated starting from the powder of the group having a large grain diameter for each group. For example, in the case of collection and separation in the 3 stages, coal char is collected in a dust collector in the first stage and almost all of the unreacted desulfurizing agent and part of the desulfurization product (e.g., CaS) are collected in the second stage. The desulfurization product and a trace amount of the unreacted desulfurizing agent are collected in the third stage.

Title: Color image reader
Inventor: ISHIDA TADASHI
IPC: G02B7/02
Filed: 1995-04-02
Abstract: PURPOSE: To prevent the contrast of a read image from lowering by providing a slit used to receive only a required luminous flux only into an optical path in the color image reader. CONSTITUTION: A light from a light source 1 is emitted to an original 6 placed on an original platen 61, a light reflected in a read position 63 is formed by a lens 3 via a reflection mirror 2 and the formed image is read by a photoelectric conversion element 4. Then a case 5 is provided to enclose other than a 1st slit 51 taking the reflected light and the transmitted light from an original face 62 and a 2nd slit 52 is arranged in front close to a lens 3 just before the photoelectric conversion element 4 in the case 5. Thus, even when an undesired light for image reading passes through the 1st slit 51, it is blocked by the 2nd slit 52, resulting that the contrast of the read image is improved in an excellent way to prevent the deterioration in reproducibility of a high density image especially.

Title: Priority determining circuit
Inventor: ISHIKAWA AKIHIKO
IPC: G06F3/00
Filed: 1983-06-08
Abstract: PURPOSE:To facilitate the alteration of priority by providing two priority determining circuits, a selecting circuit which selects the output of either one, and a switching circuit which switches the output of the selecting circuit. CONSTITUTION:When a JK-FF3 is reset with an external signal W to generate a Q output ''0'' , X=X1, and Y=Y1 regardless of the state of the JK-FF2, so that the priority determined by a priority encoder P1 is signified. Then when an FF2 is reset and the FF3 is set, X=X2, and Y=Y2, so the priority determined by a priority encoder P2 is signified. When the FFs F2 and F3 are both set, both gates G2 and G3 output ''1'', so X=X1 and Y=Y1, or X=X2 and Y=Y2 according to whether an FF1 is reset or set. The FFF1 is inverted every time request signals A and B are generated at the same time, so the priority level is changed every time contention occurs.

Abstract: PROBLEM TO BE SOLVED: To impart a cubic effect and feeling of high quality and at the same time prevent damage by providing a pattern display panel formed by laminating light absorption, carbon fiber textile pattern, and light transmission layers on a substrate. SOLUTION: For example, in a display plate 10 for a clock, on a substrate 11, a light absorption layer 12 that is a black coating film, a plating film, or the like, a carbon fiber textile pattern layer 13 where carbon fiber is woven in a pattern such as plain weave for hardening by a transparent resin, a pattern display layer 15 consisting of a light transmission layer 14 that is a resin coating film, a glass plate, or the like, and an index 16 for indicating an hour character. In the display plate 10 being composed in this manner, the intensity of reflected light appears at the minute uneven part of the pattern, and the intensity is changed into the shading of a color tone for achieving a cubic effect.  Also, when the reflected light from a texture pattern is transmitted through the light transmission layer, the reflected light is refracted, thus giving depth to the texture pattern, and changing the pattern according to an angle for viewing the pattern for visual recognition. Textile being woven by carbon fiber has superior strength and chemical characteristics, and cannot be easily broken.

Title: Vertical furnace
Inventor: IMAOKA KAZUNORI
IPC: H01L21/205
Filed: 1984-05-21
Abstract: PURPOSE:To prevent economically shorter life even if the diameter of a furnace core tube is made greater and to reduce the deterioration of a wafer by heating the end zone contiguous to the bottom of a center zone with a lower heater which is different from an upper heater which heats the end zone contiguous to the top of the center zone. CONSTITUTION:If the length of a lower heater 4 is made longer than hitherto, the effect of heat dissipation of the lower end of a furnace core tube 1 against the lower part of a center zone (a) is reduced and the heating rate of the lower heater 4 can be reduced from hitherto and simultaneously, the maximum temperature at an end zone (b) can be lowered. By making the heating rate of an upper heater 5 equal to the heating rate of the lower heater 4, the length of the upper heater can be reduced and if the length of the lower heater is made longer, the length of the center zone (a) is not made shorter but can rather be made longer. Thus, even if the diameter of the furnace core tube 1 is made greater, the economically shorter life of a vertical furnace can be prevented and the deterioration of a wafer can be reduced comparing to hitherto even if the temperature of heat treatment is higher.

IPC: G02B6/35
Filed: 1982-06-16
Abstract: PURPOSE:To obtain an optical switch which decreases attenuation of light and is simple and inexpensive, by the constitution wherein the forward end parts of a pair of optical fibers disposed so as to face each other are immersed and are not immersed in deformable magnetic fluid having no light transmittivity. CONSTITUTION:An electromagnet 15 is not energized while a switch 8 is held open. The magnetic fluid 13 in a box body 11 in this stage is attracted downward by a permanent magnet 14 and optical fibers 1, 2 are held immersed in refractive index matching liquid 12. The light propagating in the fiber 1 is transmitted through the liquid 12 into the fiber 2. When the electromagnet 7 is energized by closing the switch 8, the magnetic fluid 13 concentrates toward the central part where the magnetic field in the box body 11 is strong, and the forward end faces of the fibers 1, 2 are immersed in the fluid 13. The light propagating in the fiber 1 is interrupted by the fluid 13. The attention of light is thus decreased and the simple and inexpensive optical switch is obtd.

IPC: G06F12/08
Filed: 1998-04-14
Abstract: PROBLEM TO BE SOLVED: To control a cache including a plurality of entries by substituting one alternative entry, which is different from an entry for substitution discriminated among entries, in response to a contention between a 1st and a 2nd caching operation request. SOLUTION: 1st and 2nd caching operation requests are received. Then one of entries in the cache is discriminated for substitution in response to the reception of the 2nd caching operation request. Here, if there is a contention between the 1st and 2nd caching operation requests, one alternative entry which is different from the entry for substitution is substituted in response. For example, a multiprocessor type data system 10 is equipped with more than one processors 12. Each processor 12 includes an on-board type level-1(L1) cache 14 which operates as a local storage device for instructions and data.

Title: Strain detector
Inventor: IKEDA HIDEO
IPC: G01L3/10
Filed: 1989-04-22
Abstract: PURPOSE:To prevent errors in strain detection from occurring by forming the bearing parts of the bearing of a driven shaft with nonmagnetic material. CONSTITUTION:Bearing parts 15 and 16 of bearings 2 and 3 are formed of nonmagnetic material such as copper, aluminum based alloy, ceramics or the like. Since the bearing parts 15 and 16 are formed of the nonmagnetic material, the bearing parts are not magnetized even if an external magnetic field is applied on the said parts. Therefore, magnetic fluxes are not generated from the bearing parts 15 and 16. The magnetic operating points of strain detecting layers 4 and 5 are not affected, and errors in strain detection can be prevented.
