Title: Regenerating method of permselective membrane
Inventor: KAMIYAMA YOSHIYASU
IPC: B01D65/06
Filed: 1982-09-24
Abstract: PURPOSE:To restore easily the decreased performance of a permeable membrane by treating an org. material having a carboxylic group deposited strongly on a membrane surface with a neutral aq. soln. of alkali metals and/or alkaline earth metals. CONSTITUTION:Ethylenediamine modified polyepichlorohydrin and isophthaloyl chloride are crosslinked on a polysulfone ultrafilter membrane, whereby a flat film-like composite film is obtd. When such membrane is mounted in a flow type cell and the process liquid extract of a medical plant consisting essentially of org. materials having carboxylic groups is supplied to the cell continuously for 199hr under 40kg/cm<2> at an ordinary temp., the rate of permeation decreases from initial 0.67m<3>/m<2>.day to 0.38m<3>/m<2>.day. Thereupon, when a 2wt% aq. soln. of magnesium sulfate is circlated and supplied to the cell for one hour under the conditions of 30 deg.C and 5kg/cm<2> pressure, the rate of permeation is restored up to 97% of the initial rate.

Title: Optical recorder and reproducer
Inventor: YOSHIDA TOMIO
IPC: G11B7/09
Filed: 1980-11-27
Abstract: PURPOSE:To secure focus control by providing a means of starting, stopping and restarting the focus drawing operation of irradiating light according to the states of a focus control signal and a guide-track traverse signal. CONSTITUTION:When a signal FON is inputted to a terminal K, switches 24 and 26 turn on between terminals p2 and r2, and p3 and r3, allowing an aperture lens to approach a disk. When a focus error signal DI increases above the Vthl of a comparator and the disk is judged to be within focus drawing range, the signal Q1 of an FF29 goes down to an L to turn off switches 26 and 26, and a switch 22 turns on between terminals p1 and r1 to turn on a focus control loop I. As a recording material surface is brought under focus control, a guide- track traverse signal inputted to a terminal S decreases below the set value Vth2 of the comparator 37 and the delay pulse G of a delay pulse generating circuit 31 is intercepted by an AND gate 34 to hold a focus-controlled state, but when the signal S is high, the focus drawing operation is repeated through the output of the gate 34, thus performing the focus control securely.

Abstract: PROBLEM TO BE SOLVED: To enhance efficiency by connecting a heat exchanger, which is used as a hot water supply source and provided in an exhaust gas passage of an exhaust gas case connected to a hot water boiler and its exhaust gas opening to a snow melting element which uses hot water as a heat supply source. SOLUTION: A road surface snow melting element 4, a roof snow melting element 6 and a first snow melting element in a snow melting tank 8 are connected to a hot water boiler 2. Then, a heat exchanger 13 is set up to an exhaust gas passage in an exhaust gas case 12 connected to an exhaust opening of the hot water boiler 2, thereby connecting the heat exchanger 13 to a second snow melting element in the tank 8. Then, hot water from the boiler 2 is circulated through the snow melting elements 4 and 6 and the first snow element in the tank 2 while hot water from the heat exchanger 13 is circulated through the second snow melting element in the tank 8. Since the hot water from the hot water boiler 2 and the heat exchanger 13 is circulated through the snow melting element in the tank 8, a snow melting capacity is enhanced.  This construction makes it possible to make the most use of heat energy with a single boiler without any waste and melt snow effectively.

Title: Current command generator for synchronous motor
Inventor: IMAZEKI TAKASHI
IPC: H02P21/22
Filed: 1984-08-13
Abstract: PURPOSE:To suppress a starting current flowed to a motor without pulsating of a motor torque by reducing a slip target frequency at motor starting time. CONSTITUTION:A slip frequency command generator 42 has a slip frequency calculator 48, a slip frequency corrector 50. The corrector 50 calculates a slip frequency command WS controlled to be reduced from the normal frequency at the motor starting time. Thus, the slip target frequency is reduced at the starting time of the motor 10, thereby decreasing a drive current flowed from an inverter main circuit 12. Accordingly, an excess motor drive current is not flowed at the motor starting time, thereby preventing a defect due to the cause. Since the amplitude control of a conveying triangular signal is not performed and the slip frequency WS decreases, no pulsation occurs in the motor torque.

CONSTITUTION:A case, a plurality of magnets 12, and a cover 14 are inserted into a yoke 11. A thin caulking portion 19 is formed at the outer circumferential side. Then the caulking portion 19 of the yoke 11 is folded toward the inner circumferential side. Consequently, the tip of the upper flange section 43 of the cover 14 is pressed toward the inner circumference and secured to the yoke 11. Consequently, the upper flange section 43 of the cover 14 functions as a resilient body for pressing the top of the magnet 12, and the magnet 12 is secured to the yoke 11. By such arrangement, the magnet 12 is secured reliably and the work process is shortened.

Abstract: PURPOSE:To eliminate the need for resetting the correspondence between a commodity selection switch and a commodity storage column despite rearrangement of the sample commodities by providing a means which memorizes the correspondence between the sample commodities and the commodity storage column numbers, a communication means which performs the communication with a secondary control means, and a means which controls the secondary control means. CONSTITUTION:A 1st control means 1b of a submicrocomputer 1 temporarily stores a switch signal when a commodity selection switch 4 is pushed. When a request is received from a main microcomputer 2 for data, the means 1b decides whether the signal of the switch 4 is stored or not. If stored, the data on the sample commodities are transmitted through a communication means 1c. If not stored, a signal showing the absence of data is transmitted. When the data on the sample commodities are received by the microcomputer 2, a 2nd control means 2b selects the sales commodity data that are coincident with the sample commodity data out of a sales commodity data storage means 2a and sells the commodity of the corresponding column through 8 commodity transfer means.
