Title: Cleaning device for bathtub
Inventor: MIKUCHI HIROSHI
IPC: B01D35/027
Filed: 1986-02-10
Abstract: PURPOSE:To secure cleaning of bathtub water and also grade up quality of installation of unit by providing a bathtub with a cleaning unit of special structure and a heater of bathtub water with a circulation pump for circulating bathtub water. CONSTITUTION:By circulating water by a circulation pump 16, an ejecting action is generated in a nozzle section having an ejecting fountain head 8a, by which supernatant of bathtub is sucked into a suction section consisting of a suction pipe 22 and the like through a filter 17. Refuses such as hair, dirt and the like are removed from supernatant containing floatings 6 sucked at that time, and water without refuses is returned to a bathtub 1 by ejecting action at the nozzle section. On the other hand, installation of said cleaning unit is completed simply by installing a cleaning unit 3 consisting of said nozzle section, suction section and the filter 17 to the bathtub 1 and connecting a heater 13 for bathtub water with the bathtub.

Title: Liquid crystal device and electronic apparatus
Inventor: SAKATA HIDEFUMI
IPC: G02F1/1343
Filed: 1999-02-04
Abstract: PROBLEM TO BE SOLVED: To provide a technique capable of suppressing the occurrence of light leakage and a disclination line by suppressing the occurrence of an abnormal alignment region at the time of voltage impression. SOLUTION: The liquid crystal display device constituted by holding liquid crystal (30) between a pair of substrates (an active matrix substrate 10 and a counter substrate 20) and forming electrodes (pixel electrodes 12) to at least one substrate of a pair of the substrates is formed with slopes (tapers 12a) inclined with respect to one substrate plane at the electrodes. As a result, the light leakage from the boundary parts between the pixels may be prevented when the voltage is impressed to the electrodes. Such prevention is achieved by controlling the electric lines of force of the transverse electric fields impressed between the electrodes by the slopes formed at the electrodes. The light leakage from conventional abnormal alignment region can be suppressed by the formation of the slopes.

Title: Light signal waveguide device
Inventor: CHRISTOPHER RICHARD DORR
IPC: G02B6/34
Filed: 1998-02-09
Abstract: PROBLEM TO BE SOLVED: To occupy only small physical volume and to actualize spectrum response having nearly one dominant pass band by monotonously varying the angles between the center axis of a waveguide coupler and waveguides from one waveguide to another. SOLUTION: A pass band set other than the dominant pass band is suppressed by specifying differences in length among waveguide grating arms 103, 105, and 107 according to such a mathematical function that the differences in length among waveguides increase or decrease. In this case, a difference (ΔL) in length between two adjacent waveguides (m) and (m-1) is equal to the sum of an arbitrary constant (k) and (A×m) to the respective waveguides. Here, A is a positive or negative real number. Further, the angle a(m) that an (m)th waveguide has to the center axis of a 2nd waveguide coupler 102 is a nonlinear function, (j) is an arbitrary constant, and B is a real number; and the angle Δαin angle between the (m)th waveguide and (m-1)th waveguide is nearly equal to j+B×M.

Title: Instantaneous operation lift tool
Inventor: TAKAHASHI ATSUSHI
IPC: B66D3/18
Filed: 1996-01-08
Abstract: PROBLEM TO BE SOLVED: To enable locking and unlocking of drop force of hung object for a string by locking a rotary body which guides the string and a cylindrical body on which the string is wound by using a ratchet teeth and regulating the movement of the rotary body itself by a heart cam. SOLUTION: A compression spring presses a gear having a spiral groove in its inside diameter, and the gear rotates for a screw shaft having an opposing spiral groove to convert force of the compression spring to rotation force. The rotation of the gear is transmitted to a first gear part, a second gear part, and a gear part of a drum to apply a hoisting force to a lift string 7 which is wound around a drum. The stop and movement of the lift string are done by locking and releasing of a claw part 8a of a rotary body 8 for a ratchet tooth part 5a provided in a part of an operation gear.  Since an operation string 9 which is wound in the spiral groove of the operation gear moves in contact with the rotary body 8, a guide 8 moves centered on a shaft part of a first case due to its contact force, the locking and releasing are done due to the movement of the claw part 8a based on the relation between a link 10 provided in such a manner that it is in the interlocking relationship with an arm part 8b and a heart cam part 3b of the first case.

Title: Vaporization of liquefied natural gas and its energy recovering method
Inventor: KUBOTA TAKASHI
IPC: F01K25/10
Filed: 1979-03-14
Abstract: PURPOSE:To enhance energy recovering efficiency, by using as medium a mixture of soft hydrocarbons having a composition the condensation curve of which is substantially equal to the vaporization curve of liquefied natural gas (LNG). CONSTITUTION:As a medium, there is used a mixture of soft hydrocarbons having a composition the condensation curve of which is substantially equal to the vaporization curve of LNG. Here, if vaporizing temperature of LNG is raised by increasing vaporizing pressure of LNG, for instance, from 8.5kg/cm<2>-70kg/cm<2>, vaporization curve of LNG is made to closely conform to the condensation curve of medium, so that cold heat possessed by LNG can be recovered most efficiently. At the same time, by causing linear expansion of re-gasified natural gas and thereby recovering cold heat of LNG in a lower temperature region, energy possessed by LNG can be recovered more efficiently.

Title: Magnetic recording medium
Inventor: SHINOHARA KOICHI
IPC: G11B5/738
Filed: 1987-02-10
Abstract: PURPOSE:To decrease an error rate at the higher density of digital recording by laminating a thin barium ferrite film and thin ferromagnetic metallic film onto a high-polymer film having an under coating layer. CONSTITUTION:This recording medium is constituted by disposing the thin barium ferrite film 6 on the high-polymer film 4 having the under coating layer 5 and disposing the thin ferromagnetic metallic film 7 thereon. The noise and error rate arising from the nonuniformity which is generated by the under coating layer 5 are uniformized by the thin barium ferrite film 6 and, therefore, the characteristics of the thin ferromagnetic metallic film 7 on the magnetic recording layer are sufficiently effectively utilized. The good error rate is thereby assured without fluctuating said rate at the time of executing the high-density digital recording.

IPC: C01G49/02
Filed: 1982-02-26
Abstract: PURPOSE:To efficiently obtain high purity iron hydroxide from an aqueous iron chloride soln. in a simple and economical manner by oxidizing iron ions in the soln., subjecting the soln. to extraction with a solvent causing ionic association and back extraction with water, and neutralizing a separated aqueous soln. phase. CONSTITUTION:An aqueous iron chloride soln. having >=3mol/l chlorine ion concn. is treated to oxidize bivalent iron ions to tervalent ions. The oxidized soln. is mixed with a solvent causing ionic association, and the mixture is separated into an aqueous soln. phase and a solvent phase after solvent extraction to purify the iron chloride soln. The separated solvent phase is mixed with water, the mixture is separated into a solvent phase ad an aqueous soln. phase after back extraction, and the separated aqueous soln. phase is neutralized to obtain iron hydroxide. When the chlorine ion concn. of the iron chloride soln. is <3mol/l, it is difficult to extract tervalent iron ions by solvent extraction, so in case of <3mol/l concn., it is desirable to adjust the soln. to >=3mol/l concn.
