Title: Method for concentrating solution
Inventor: INOUE KENICHI
IPC: B01D61/00
Filed: 1995-09-20
Abstract: PROBLEM TO BE SOLVED: To increase the concentration of insoluble components in raw water containing insoluble components such as solid suspended substances and colloid by the permeation of the medium of a low osmotic pressure solution to a high osmotic pressure solution through a permeable membrane. SOLUTION: A concentrator 1 is divided into a raw water vessel 3 for a low osmotic pressure solution and a salt water vessel 4 for a high osmotic pressure solution, and a permeable membrane 2 is set between the two vessels. Raw water 10 containing insoluble components is fed into the raw water vessel 3, salt water 11 containing salt which is not contained in the raw water 10 or the concentration of which is higher than that of the raw water 10 is fed into the salt water vessel 4, and they are allowed to stand. A medium, e.g. water, in the raw water 10 moves to the salt water 11 in the vessel 4 through the permeable membrane 2. As a result, the concentration of insoluble components in the raw water 10 in the vessel 3 increases, while the concentration of the salt water in the vessel 4 decreases.  In this way, the insoluble components in the raw water 10 can be concentrated without the use of external energy.

Title: Length measuring interferometer
Inventor: WADA YORIO
IPC: G01B9/02
Filed: 1991-09-20
Abstract: PURPOSE:To make a splitting optical element such as a polarizing prism small and to facilitate optical alignment without using a corner cube by obliquely casting convergent light into a length measuring interferometer. CONSTITUTION:The parallel luminous flux of incident light 1 containing two polarized-light components (linear polarized-light components which are mutually vibrated in the perpendicular direction within the vertical plane in the advancing direction of light) is condensed with a first lens 2 and obliquely cast into a splitting optical element 3. The transmitting and reflecting divergent lights, which are split in the element 3, are made to be the parallel luminous fluxes through second and third lenses 5 and 11. The luminous fluxes are cast into a vertically located moving mirror 7 and a fixed mirror 13 through 1/4-wavelength plates 6 and 12. The measuring light and the reference light of the parallel luminous fluxes reflected from the mirrors pass through the same wavelength plates 6 and 12 and the lenses 5 and 11 and become the convergent lights. The cat's eyes are formed, respectively, with a reflecting mirror 8 provided at a converging point and the lenses 5 and 11. Thus, the interval between the respective beams of the measuring light and the reference light can be widely set arbitrarily, and the alignment of the optical system is made easy.

Title: Method and device for controlling actuator in construction machine
Inventor: ASAKAGE TOMOHIKO
IPC: E02F9/20
Filed: 1996-09-12
Abstract: PROBLEM TO BE SOLVED: To make appropriate the actuation of a preventive means against shocks, by automatically judging an abrupt operation of an operational lever in a construction machine like a hydraulic shovel whether it is an operation caused by a singly manipulating motion or an intentional repeating motion. SOLUTION: When an operator manipulates manually an operation lever 11, an operation signal M is input in a controller 13 through a manipulated variables detector 12 and the working speed of a hydaulic actuator 21 is controlled. When an hourly variables of the operation signal M is larger than a preset value, it is converted to a restrictive signal suppressing it under the preset value to avoid a shock resulting from the abrupt operation, in the controller 13. But when the value of the operation signal M has crossed a specified number of times the basic value set at both positive and negative sides within a specified time interval, it is judged that the repeating abrupt operation has been intentionally done and the operation signal M is not converted to the restrictive signal. Accordingly, mud stuck on the machine can be removed done by vertically and vigorously shaking the bucket of a hydraulic shovel and vigorously moving the crawler back and forth.

IPC: G03C7/392
Filed: 1990-09-12
Abstract: PURPOSE:To obtain excellent aldehyde resistance, etc., without deteriorating film properties and to prevent the degradation in coating viscosity by using a specific compd. as an aldehyde scavenger. CONSTITUTION:At least one kind of the compds. expressed by formula are incorporated into at least any one layer of photograph constituting layers. In the formula, R<1> denotes a hydrogen atom or univalent substituent, for example, alkyl group; R<2> denotes a group having >=0.2 Hammette sigmap value, for example, cyano group. The Hammette sigmap value of the substituent is preferably >=0.2 and <=1.0. quinone diimine is consumed in, for example, the photosensitive material if the value is lower than this range. Such consumption leads to a degradation in the color developing density or is the cause for staining. On the other hand, the reactivity with the quinone diimine is ow but the reactivity with harmful materials, such as formaldehyde, is low and such is not effective if the Hammette sigmap value is higher than this range. Gelatin subjected t a cation exchange treatment is incorporated into at least one layer of the layers contg. the compds., by which the excellent formaldehyde resistance, etc., are provided and the problem of the degradation in the viscosity of the adding soln. is solved.

Title: Method for treating drainage containing dimethyl sulfoxide
Inventor: KITAGAWA MIKIO
IPC: C02F3/30
Filed: 1992-09-11
Abstract: PURPOSE:To prevent the generation of odor and to materialize low cost, high efficiency treatment by returning at least a part of sludge separated by a solid- liquid separator to an anaerobic treatment tank and an aerobic treatment tank as return sludge. CONSTITUTION:Drainage containing dimethyl sulfoxide (DMSO) and drainage containing organic compounds other than DMSO are fed into an anaerobic treatment tank 1 to be treated. DMDSO in the drainage is converted into dimethyl sulfide (DMS) by anerobic treatment without supplying oxygen. Since the gas generated by the anaerobic treatment contains DMS, the tank 1 has a completely closed structure. The gas is led to a biologically deodorizing device 4 to eliminate the odor. Effluent from the treatment tank 1 is transferred into an aerobic treatment tank 2, where DMS is further decomposed by oxidation. The exhaust gas is led into the biologically deodorizing device 4, and the gas removed of its odor components is discharged outside the system. The water treated is sent to a sedimentation vessel 3 for solid-liquid separation, while the sludge separated is returned respectively to the aerobic treatment tank 1 and the anaerobic treatment tank 2 as return sludge.

Title: Fastening tool for column and its method
Inventor: IRI CHIKA
IPC: E04G21/16
Filed: 1996-09-13
Abstract: PROBLEM TO BE SOLVED: To easily confirm the fastening completion of a screwlike fastener from the outside of a column by braking a brittle part provided on the screwlike fastener by the screwing a fastening tool having a claw part and installable only in one direction by a fixed torque to separate a screw body, and drawing only a tool engagingly fixing part out of the column. SOLUTION: A claw part 32 provided on a fastening tool 30 is pressed around a bolt 21 with extension, and reaches or passes a brittle engaging part 21F closer to a screw body 21A side from a tool engagingly fixing part 21E to nip the circumference of the tool engagingly fixing part 21E. When a fastener engagingly fixing part 31 is engagingly fixed by the tool engagingly fixing part 21E, the claw part 34 passes the brittle engaging part 21F and makes contact with a slit 21G. When a fixed torque is attained by the screwing operation of the fastening tool 30, the brittle engaging part 21F of the bolt 21 is broken, and the bolt 21 is screwed to a female screw part. The fastening tool 30 is pulled out while only the tool engagingly fixing part 21E from which the screw body 21A of the bolt 21 is separated is held thereby.  Since the fastening tool 30 does not hold the screw body 21A, the fastening completion of the bolt 21 by a fixed torque can be visually confirmed from the outside.
