Title: Channelized receiver
Inventor: MATSUBARA KOJI
IPC: H04B1/26
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To prevent two or more frequencies per received signal from being calculated by eliminating a rabbit ear signal passing through a surface acoustic wave SAW filter in the propagation process of the signal. SOLUTION: Analog comparator circuits 5 are connected to a SAW filter bank 1 configured by SAW filters with different center frequencies placed side by side via logarithmic amplifiers 2. A frequency calculation circuit 4 calculates the frequency of a received signal on the basis of signals passing through the analog comparator circuits 5. The receiver is provided with a slice level generating circuit 6 that covers the frequencies of the entire frequency band of the received frequencies. The slice level generating circuit 6 generates a slice level that distinguishes a rabbit ear signal from a main signal on the bases of the level of the received signal. The analog comparator circuits 5 compare the signals passing through the SAW filter bank 1 with each slice level to eliminate the rabbit ear signal.

Title: Electrophotographic recording method
Inventor: TETSUYA SHINJI
IPC: G03G15/04
Filed: 1987-04-03
Abstract: PURPOSE:To enable an optical write head to come into contact with a photosensitive body to miniaturize a device by developing an optical image by a developing machine to which a voltage is applied after writing the optical image on the photosensitive body consisting of a photoconductor whose light exciting carrier life is long. CONSTITUTION:A photosensitive body 1 consists of the photo-conductor whose light exciting carrier life is long, and the optical image is developed by a developing machine 4 to which the voltage is applied after being written on the photosensitive body and is transferred and fixed to a paper. Since it is unnecessary to electrify the photosensitive body 1 before write of an optical image 20, dispersion of the electric charge due to contacting is prevented. As the result, the head for optical write can be brought into contact with the photosensitive body. Thus, it is unnecessary to secure the optical path length demanded by the focal length of a lens and the device is considerably miniaturized.

IPC: H01M10/39
Filed: 1983-05-13
Abstract: PURPOSE:To obtain a beta-alumina thin film wherein the C-plane of the crystal is oriented perpendicular to the film face, by immersing an alumina thin film containing a small amount of the oxide of Mg, Li, etc. in a solution containing an Na compound, thereby impregnating Na into the thin film. CONSTITUTION:PVA and a small amount of the oxide of Mg, Li, etc. are added to an aqueous solution containing ultrafine colloidal particle of Al(OH)3 or AlCl3, and the mixture is dripped on a horizontal plate and dried. The obtained thin film is baked at about 1,400 deg.C in air to obtain an alumina thin film having a thickness of 1-100mum and containing a small amount of the oxide of Mg, Li, etc. The thin film is immersed in an aqueous solution containing an Na compound (e.g. NaOH), dried, and baked at about 1,250 deg.C in air to effect the diffusion of Na from the surface of the film to the inside of the film. A beta-alumina thin film having a thickness of 1-100mum and composed of crystals having C- plane oriented perpendicular to the film face can be manufactured by this process.

Title: Desulfurization of exhaust gas
Inventor: MICHIKI HIDEYUKI
IPC: B01D53/77
Filed: 1996-04-04
Abstract: PROBLEM TO BE SOLVED: To eliminate the difficulty mutually separating two kinds of crystals of magnesium hydroxide and gypsum dihydrate by returning a mixed slurry of magnesium hydroxide and gypsum dihydrate obtained in a double decomposition process to both of a desulfurizing process and an oxidizing process and taking gypsum dihydrate out of the system from the treated solns. of both processes. SOLUTION: The treated soln. returned to a desulfurizing column 1 and an oxidizing tank 3 from a double decomposition tank 4 is a mixed slurry of magnesium hydroxide and gypsum dihydrate but magnesium hydroxide in the treated soln. from a desulfurizing process is consumed as a desulfurizing agent and a hydrogen chloride removing agent. If the operation condition of the desulfurizing column 1 is held to concn. equal to or less than the solubility of formed magnesium sulfite, the suspended substance in the treated soln. of the desulfurizing process becomes only gypsum dihydrate.  Since magnesium hydroxide contained in the treated soln. of the oxidizing process and returned from a double decomposition tank 4 is consumed as a nuturalizing agent of sulfuric acid formed by oxidation to be converted to magnesium sulfate, the suspended substance in the treatment soln. of the oxidizing process is only gypsum dihydrate. Therefore, gypsum is easily separated from these treated solns.

Filed: 1980-06-20
Abstract: PURPOSE:To expel bubble between an intended material and an adhesive tape for more beautiful appearance and decorativeness by means of a positioning member adapted to position the part of an elastic sheet corresponding to the material properly above the material. CONSTITUTION:When a belljar 5 is lowered onto a base body 1, an elastic sheet 6 is so positioned to bridge the upper end of a block 11. At this point, as a vacuum pump is driven to vacuumize, the elastic sheet 6 hang like U especially between blocks 11 and 11 so much as to come into linear contact with an adhesive tape 9 at the lowest position 6a. With further vacuumization, the contact with the adhesive tape 9 spreads horizontally centered on the position 6a to cover the entire part of the adhesive tape 9, hence applying pressure entirely. This expels air present between the tape 9 and an intended material 7 thereby eliminating bubbles there.

Filed: 1982-05-17
Abstract: PURPOSE:To increase the damage strength of a protective diode without increasing the series resistors from a substrate to a junction by arranging a low density substrate on a line of P<+> type diffused region formed on a P type semiconductor substrate. CONSTITUTION:P<+> type diffused regions 8 of the same conductive type are formed on a P type semiconductor substrate, a low density substrate 7 is arranged on a line 15 of the region 8 which can be readily damaged, thereby alleviating the current which flows on the line 15 and preventing the concentration of an electric field of an electrostatic pulse. Since series resistors r from the substrate are arranged with P<+> at the periphery of the exposed part 19 of the substrate in a DC manner, they do not increase more than required, and can be controlled to suitable value by altering the size of the exposed part 19. In the drawing, an example of employing this invention can be employed in a protective diode between an N-ch, MIS-FET substrate and input, and can be employed similarly for a protective diode between P-ch, MIS-FET substrate and input.

Abstract: PURPOSE:To approximate a positioning error to zero while the gain of a control system can be maintained at a stable value regardless of a feed rate, especially a fine feed rate, by permitting a feed direction discriminator to switch an off-set drive force. CONSTITUTION:The direction discriminator 9 is comprised of a flip flop 21 to temporarily store the feed direction and an AND gate 22, and an off-set switch 10 comprised of analog switches 23 and 24. A feedback circuit 8 outputs off-set voltages VOSP and VOSR that can resist a frictional force FF at the time of moving a load 5 in a positive direction and a frictional force FR at the time of moving the load in the reverse direction. The direction discriminator 9 discriminates the feed direction, and the off-set drive force against the frictional force of the load in the direction is switched and given. As a result, how matter small the feed rate is, the positioning error can approximate to zero while the gain of the control system is maintained in a stable range.
