Title: Method for separating dried easily adsorbable gas from gaseous mixture containing hygroscopic moisture
Inventor: HATANO TAKAHARU
IPC: B01D53/04
Filed: 1990-02-13
Abstract: PURPOSE:To miniaturize an apparatus and to reduce power consumption by roughly separating hygroscopic moisture from raw material gas under low pressure by a cooling type dryer and subsequently concentrating the gas to take out a small volume of gas as a product and dehumidifying this gas in a pressurized state equal to or more than atmospheric pressure. CONSTITUTION:A moisture-containing gaseous mixture composed of multi- component gas is separated into hardly adsorbable gas (e.g. O2) and easily adsorbable gas (e.g. N2) according to a pressure swing method using an adsorbent, and the dried easily adsorbable gas is separated as product gas. At this time, hygroscopic moisture is roughly separated from raw material gas under a low pressure condition of 1kg/cm<2>G or less by a cooling type dryer 2. Next, the raw material gas is supplied to pressure swing type gaseous mixture separators 3A-3D and the easily adsorbable gas separated by the separators 3A-3D is dehumidified by dehumidifiers 8A, 8B using a pressure or temp. swing type adsorbent and the adsorbable gas in a dried state is separated in a pressurized state equal to or more than atmospheric pressure. As a result, the apparatus can be miniaturized and power consumption can be reduced.

Filed: 1978-03-17
Abstract: PURPOSE: To prevent piping from corrosion cracking due to stress by simple operation in which both ends of pipe are closed only to cool and freeze liquid within the pipe.  
     CONSTITUTION: On the periphery of austenitic steel pipe 3 put between a coolers 5, 51 is mounted similarly a cooling container 13 provided with a liquid nitrogen inlet 7 and a heat insulator 6. Unfrozen water sandwiched between cut-off frozen portions 10, 11 is cooled and frozen to form frozen portion 12 while bringing about approximately 4% expansion of volume. Since it is constrained in the longitudinal direction by the frozen portions 10, 11, said expansion of volume is directed radially to give the steel pipe 3 about 2% strain. Next, frozen portions 10 to 12 are heated to be returned to water while the inner surface of the steel pipe 3 is subject to residual compressive stress rather than residual tensile stress, one of causes of corrosion cracking due to stress, to prevent satisfactorily same.

Abstract: PURPOSE:To minimize rusting of constituent parts of hot well constituting parts of a condenser, by preventing stagnation of condensate in recessed portions of a hot well box. CONSTITUTION:A means for preventing stagnation of condensate, consisting of a sparger 8 connected to a water conduit 1, is disposed in a hot well box 4 consisting of a condenser body 2 and a bottom plate 3, in the manner that it is extended along the condenser body 2, and many ports 9 for ejecting condensate are provided on the wall surface of the sparger 8. Condensate carried into the hot well box 4 via the water conduit 1 is ejected toward the condenser body 2 from the ports 9 of the sparger 8, and  after being distributed in the box 4 while flowing toward the corner portions of the condenser body 2, reinforcing plates 7 and the hot well box 4 and recesses formed at the root portion of the reinforcing plates 7, is then discharged to the outside from an outlet pipe 6 via an outlet sump 5. Thus, since the recesses formed at the corners of the hot well box 4 and the root portions of the reinforcing plates 7 are always subjected to vertical movement of condensate, it is enabled to eliminate stagnation of condensate at these recesses that is caused in the conventional arrangements in which the condensate flow is horizontal. Therefore, rusting of the constituent parts of the hot well box 5 can be minimized.

IPC: A61B6/00
Filed: 1984-02-22
Abstract: PURPOSE:To obtain the processing capable of realizing a data compression ratio efficient for various pictures by extracting directional components from a partial construction of a picture, and selecting automatically the most suitable picture scanning system from the information. CONSTITUTION:After a picture read from a film reader unit 61 is A/D-converted, it is stored in a magnetic disk 63. An image processor 62 chops a partial picture from a picture in the magnetic disk 63 and extracts directional components with gradient. Then histgrams of values exceeding the specific threshold are generated in each direction, and peaks of these histgrams are extracted. The image processor 62 decides whether or not the overall picture is completely processed. When the processing is finished, the next partial picture is set and the similar processing is executed. The result is encoded and the partial picture is stored in an optical disk 64. By repeating such processing by one picture, compressed pictures are stored in the optical disk 64.

Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To provide a method to convert the surface of a substrate such as glass and metals into an excellent water-repellent and oil-repellent surface in normal air. SOLUTION: A solid substrate 1 having active hydrogen on its surface such as glass or metals is dipped in a soln. of a fluoroalkyl trialkoxysilane compd. containing a mono- or ditrichlorosilane compd. which is stable in air. After taking out of the substrate from the soln., the substrate is dried to remove the solvent and then subjected to heat treatment. During drying and in the initial stage of drying of the substrate, the mono- or di-trichlorosilane compd. reacts with the active hydrogen on the substrate surface to produce hydrogen chloride, which is used to promote the reaction of alkoxysilane therewith to produce silanol and the reaction of the silanol with the active hydrogen on the substrate surface. Thus, a silane compd. having fluoroalkyl groups is formed with conjugate bonds to the substrate surface with high density.

Title: Reel motor driving circuit for tape recorder
Inventor: SHIGEMATSU NANA
IPC: H02P29/00
Filed: 1986-02-14
Abstract: PURPOSE:To enable the detection of a brush pulse free from a noise, by a method wherein a part of driving current flowing through a reel motor is drawn with a current mirror circuit and the current detected is made to flow to a reference potential point through a resistor. CONSTITUTION:In the forward driving of a reel motor 11, a transistor TrQ1 is turned ON by an output of a forward rotation side differential amplifier 17. A part of output current IC of the TrQ1 is supplied to a base of a TrQ4 through a resistance R5 and a TrQ5 of a current mirror circuit CM1 to turn ON the TrQ4. A part of the current IC flows in the direction of the solid arrow as driving current IRM of a motor 11. On the other hand, as the potential of an output terminal 16 varies with a brush pulse generated in the motor 11, a brush pulse P can be detected by checking the voltage of the terminal 16 with respect to the ground. At this point, for example, even when a noise happens to overlap a power source voltage VCC and further is carried on the current IRM and IB and a detection current IDET through the TrQ1, the pulse P detected at the terminal 16 will be converted into an earth reference thereby minimizing the effect of the noise.

Title: Take-up apparatus for tape
Inventor: INOUE HISAYOSHI
IPC: B65H23/18
Filed: 1980-03-10
Abstract: PURPOSE: To simplify the constitution of a take-up apparatus for a tape and facilitate the loading thereof by controlling the reel torque according to the angular velocity of the reel when the tape travel speed is constant while according to the signal obtained by multiplying the angular velocity and the tension together in case of a transitional travel.  
     CONSTITUTION: When the speed of a tape 1 changes transitionally, the tape tension changes, causing a tape tension detecting post 9 to fluctuate, so that the signal of a magnetism-sensitive element 11 changes. Through a high-pass filter (not shown), said signal is multiplied by the detection signal of a roll diameter detecting unit comprising a light-emitting element 14, a light-receiving element 15, an optical encoder 13 and an apparatus which is not shown. Then, said multiplication signal is added to the roll diameter detecting signal in order to control a reel driving unit 3. When the speed of the tape 1 is constant, no output is generated from the magnetism-sensitive element 11, so that the driving unit 3 is controlled according to the speed of the reel 2. Thereby, the tape travel route is simplified, and the loading of the tape 1 is facilitated.
