Title: Adaptive reference equalization device
Inventor: UESUGI MITSURU
IPC: H04B3/06
Filed: 1987-12-08
Abstract: PURPOSE:To obtain an equalization effect equivalent to that of a modem in which no reference level changes in the modem in which the reference level changes if it is constant amplitude modulation by varying the reference level adaptively by a reference level setting device. CONSTITUTION:When a baseband signal is inputted to an input terminal 1, a signal equalized by an adaptive equalizer 2 is normalized by the reference level setting device 6, and the reference level is set. Also, an equalized signal is decided by an identification device 7, and an identification value multiplying an identified result by a set reference level by the identification device 7 is outputted from an output terminal 4 to a decoding circuit as a reception signal. Simultaneously, an error between the output signal of the adaptive equalizer 2 and that of the identification device 7 is calculated by an error information feedback device 8, and when its result is fed back to the adaptive equalizer 2, the adaptive equalizer 2 corrects a tap coefficient so as to minimize the square of the error. In such a way, it is possible to obtain the equalization effect equivalent to that of the modem in which no reference level changes if it is the constant amplitude modulation.

Title: System for reproducing document
Inventor: STEPHEN J HARRINGTON
IPC: G06V10/00
Filed: 1997-11-11
Abstract: PROBLEM TO BE SOLVED: To maintain a difference of colors when a monochromatic printer is used, by processing a text printed by a color printer to print or generate an expression of lines or strokes in a format whereby colors are maintained while a distinguishing center line overwritten on the strokes is included. SOLUTION: When a stroke is a colored one, whether it is dashed is checked (S110). When the stroke is not dashed, an outline or a boundary of the stroke is generated at a module stroke boundary (S113). After the outline is generated, the interior of the stroke is processed (S114). A black or white pattern of a narrower width than a width of the stroke is set at the center of the stroke when a dash pattern is arranged. Therefore, a remaining part of the stroke can be filled with a required color, so that a large part of impacts of the color can be preserved.

Title: Preparation of acrolein and acrylic acid
Inventor: KIYOURA TADAMITSU
IPC: C07C27/12
Filed: 1989-11-30
Abstract: PURPOSE:To maintain the amount of oxygen in a fed gas in a state less than the stoichiometric amount of the oxygen required for propane to be converted and re-use the catalyst after again oxidized when the propane is oxidized on a multicomponent oxidation catalyst to prepare the subject substances. CONSTITUTION:When propane is subjected to a gaseous phase oxidation reaction on an oxidized state catalyst containing Bi, Mo and one or more elements selected from V, Ce, Nb, Co, Cr, Fe, Ag, etc., or an oxidized state catalyst containing vanadyl pyrophosphate and one or more elements selected from Ce, Nb, Bi, Mo, Ag, etc., to prepare the subject substances, the amount of oxygen in a fed gas is controlled so as to be less than the stoichiometric amount of the oxygen required for the total amount of the propane. The catalyst thus reduced is separated from the reaction system, thermally oxidized in air and subsequently again employed. The method does not have any danger of explosion because the oxygen required for reaction is supplied from the oxidized state catalyst.

Title: Optical information detecting device
Inventor: MATSUURA KEIJI
IPC: G02B21/00
Filed: 1995-11-28
Abstract: PROBLEM TO BE SOLVED: To make it possible to correct the optical length of a double made region to a desired length with a small voltage by making the optical length of the time when the voltage is not impressed from the electrode of one of the double mode channel waveguides of optical information detecting optical system different from the optical length of the other. SOLUTION: At least one of the double mode channel waveguides of the optical information detecting optical systems is so formed as to differ in the optical length when the voltage is not impressed from the electrode from the optical length of the other. For example, 20 sets of the optical information detecting optical system 101a to 101t are arranged in parallel on a lithium niobate 13 to constitute the optical information detecting device 6. These trunk double mode channel waveguides 7a to 7t are so designed as to have different values in the geometrical length by 20μm each. The reason thereof lies in that the perfect coupling length of the trunk double mode channel waveguides 7a to 7t is 400μm.

Title: Optical amplification device for wavelength multiplex transmission
Inventor: ISHIDA OSAMU
IPC: H04B10/50
Filed: 1996-11-20
Abstract: PROBLEM TO BE SOLVED: To hold light intensity per wave in remaining signal light even if arbitrary signal light extincts by individually detecting light and setting light intensity becoming maximum to be a prescribed level. SOLUTION: The outputs of respective pilot tone detectors 33-1 to 33-n are amplified in invertible amplifiers 51-1 to 51-n and are outputted as negative voltage values. Then, they are inputted to an invertible amplifier 53 through the diodes 51-1 to 51-n of inverted connection. Only a diode connected to the amplifier whose negative voltage value is the largest becomes a forward direction and it is turned on. The other diodes become the voltage state of an inverted direction and they are turned off. Since the input voltage value of the invertible amplifier 53 is matched with the largest absolute value among the negative voltage values which the invertible amplifiers 51-1 to 51-n output, the invertible amplifier 53 selects and outputs the largest value in detected signal light intensity.  A differential amplifier 71 detects a difference between the value and reference voltage, inputs it to a controller 73 and negatively feeds back/controls an exciting laser 14. Thus, the largest light intensity of signal light is kept to the prescribed level.

Title: Process for separating gas component by vacuum swing adsorbing method
Inventor: RABUI KUMAA
IPC: B01D53/047
Filed: 1993-11-16
Abstract: PURPOSE: To provide such an operation method which can yield a production gas at a high recovery rate and reduce the consumption of adsorbents and electric power consumption per production amount when separating and acquiring gaseous components from a gaseous mixture by a vacuum swing adsorption method using many adsorption beds. CONSTITUTION: When a less strongly adsorbable component is acquired as a product by using a plurality of the adsorption beds packed with the adsorbents capable of selectively adsorbing a strongly adsorbable component, this acquisition is superposed on the counter-current-like exhaust stage in a plurality of the adsorption beds after the initial decompression operation for supplying a purge gas. The pressure equalization operation between the adsorption beds is carried out by using the counter-current-like exhaust gases simultaneously discharged from the at least two adsorption beds and the gaseous mixture composed of the less strongly adsorbable component and the feed gas for repressurization of the adsorption beds in combination, by which the component gaseous product is obtained at the high recovery rate.

Thus, the smells of the fixer are decreased and the working environment and equipment corrosion are decreased. In addition, the residual thiosulfate and the after-colors are decreased and the good photographic processing is possible.

Title: Method and device for heating tube material or the like by high-frequency induction heating
Inventor: HASHIMOTO YASUO
IPC: B29L23/00
Filed: 1997-10-23
Abstract: PROBLEM TO BE SOLVED: To heat quickly a material to be heated which is long axially, such as a tube material made of hard synthetic resin and used for an oil piping or a water piping of an automobile, with uniformity as a whole and without causing deformation and distortion. SOLUTION: High-frequency induction heating is applied so as to heat quickly. A material A to be heated is held by a holder 3 which is made of a material incurring a heat loss little by a high frequency, such as fluoroplastic, and this is disposed between an upper electrode 1 and a lower electrode 2. While the holder 3 holding the material A to be heated is rotated, a high-frequency voltage is impressed. Thereby the material is heated uniformly, while deformation and distortion are not brought about since the external force of rotation does not work on the material to be heated.
