IPC: C02F3/00
Filed: 1989-03-14
Abstract: PURPOSE:To ensure prevention of water pollution due to waste effluent by recycling the waste water purified in a purifying tank instead of running it off. CONSTITUTION:The waste water resulting from the water usage for a toilet 1, a washtub 2, a bathtub 3, a cleaner 4 with miscellaneous tools, a washing stand 5 and a kitchen 6 is sent through a waste pipe 7 and an inlet 8 into a purifying tank 9. This waste water flows from a first chamber 10 and through an inlet pipe 11 into a second chamber 12 and, from there, it flows through an inlet pipe 13 into a third chamber 14 intended for contact aeration, where it is purified until the regulatory values set forth by the Japanese government are attained with a wide margin. The water thus purified flows through a sterilization tank 15 and an inlet pipe 16 into a water tank 17 for storage. The water thus stored in the water tank 17 is supplied to the toilet 1 and the washtub 2 by a pump 18 actuated by turning on a faucet 19 for the toilet 1 and the washtub 2. The resulting waste water is sent back into the purifying tank 9. This cyclic water supply is repeated. Moreover, a very fine screen 20 is provided in the sterilization tank 15 to further improve the water quality. When the amt. of waste water is decreased as it is concentrated with its increasing cyclic use, it is replenished with drinking water.

CONSTITUTION:At a guide roller 2a immediately before passage of a rotary dust removing member 3, one side of a support 1 is uniformly coated with solvent by a solvent coating device 6. Between guide rollers 2a, 2b, dust removal is made by the rotary dust removing member 3 which is capable of being in contact at a certain lap angle to the support 1 on the side coated with the solvent and is rotated at a low speed in the direction B opposite to the running direction A of the support 1. The rotary dust removing member 3 is provided with a plurality of cutting edge surfaces 10 at the periphery, and each cutting edge surface 10 is helical at an inclination angle beta to the rotary shaft 11, and a groove 12 has an appropriate rake angle alpha in the rotating direction. Therefore the dust or the like intrudes quickly into the groove 12 together with the solvent and is extruded by sideways flowing of the solvent within the groove 12.

Title: Production of high-mw polymer
Inventor: NARIMATSU SHINZO
IPC: C08F2/10
Filed: 1987-03-20
Abstract: PURPOSE:To obtain a water-soluble high-MW polymer of a high degree of polymerization, by performing aqueous solution polymerization in the presence of a catalyst while adjusting the maximum reached temperature to a specified temperature by cooling the polymerization system and drying and grinding the polymer. CONSTITUTION:A water-soluble high-MW polymer is produced in the presence of a radical polymerization catalyst by an aqueous solution polymerization process in the following manner. Namely, the maximum reached temperature in the polymerization system is adjusted to a temperature which is lower by at least 5 deg.C than the maximum temperature reached when the polymerization is performed in an adiabatic system by cooling the polymerization system from its inside and outside. The product is dried and ground to obtain the purpose high-MW polymer. The cooling is performed according to the state of polymerization by using warm water or water while the temperature is being controlled so as not to prevent polymerization. Usually, the polymerization is started after the temperature of the aqueous monomer solution is adjusted to -10-30 deg.C.

Title: Measuring method of anisotropy
Inventor: FUJISAWA KAZUO
IPC: G01N29/07
Filed: 1984-03-30
Abstract: PURPOSE:To measure exactly the anisotropy of a material to be inspected by using a spiral transmission coil and propagating the transversal ultrasonic wave polarized in the diametral direction into the material by an electromagnetic ultrasonic wave method. CONSTITUTION:When DC current is passed to an excitation coil 3, a DC magnetic field is applid to a steel plate P. On the other hand, a pulse current generating circuit 5 emits pulse current according to the trigger signal from a synchronizing pulse generating circuit 6 and passes the same to a spiral transmission and reception coil 4 by which the magnetic flux in the radial direction of the coil 3 is changed by a steel plate P and eddy current is generated on the surface of the plate P. Strain is generated in the plate P by the eddy current and magnetic field and the transversal ultrasonic wave polarized in the diametral direction is generated from the surface of the plate P. The transversal ultrasonic wave is reflected by the rear surface of the plate P and arrives at the front surface which generates the eddy current. The eddy current is detected as the voltage induced by the eddy current in the coil 4 and the detected signal is amplified 7 and is fed to a gate circuit 8. A trigger signal from the circuit 6 is applied to the circuit 8. The circuit 8 opens a gate for prescribed time and the input signal from the amplifier 7 is subjected to frequency analysis 9 by which the measurement of the anisotropy of the plate P is made possible.

IPC: A61M16/06
Filed: 1994-03-07
Abstract: PURPOSE:To prevent the fit of asthma and realize a quiet sleep by connecting directly to a hood body a positive pressure generator that creates a positive pressure atmosphere zone by sucking outer air and feeding air made clean into the hood body. CONSTITUTION:When a positive pressure generator 3 connected to a hood body 1 that covers the upper half part of a body including a head portion is operated, a fan 3b is driven by means of a motor, and pure air is delivered under pressure. That is, when outer air is sucked in by the drive of the fan 3b, it is forcedly passed through a filter 3a, so dust, pollen, ticks or the like in the air are filtered and purification is carried out. As the pressure of the hood body 1 inside is increased due to the blowing-in of the outer air, the old inside air is driven out, and a positive pressure atmosphere zone is created on the hood body 1 inside from which dust, ticks or the like have been discharged to the outside. Breathing is conducted in this, so the prevention of the fit of asthma can be effectively carried out, and at the same time a quiet sleep can be induced with the easy posture of lying, and a pleasant sleep is realized.
