Title: Controlling method for backward travel of nozzle in injection molding machine
Inventor: HARADA SUSUMU
IPC: B29C45/76
Filed: 1990-05-29
Abstract: PURPOSE:To remove the trouble in the adjustment work of a dog or a timer switch and enhance the accuracy of the backward travel of nozzle by working a selector valve by means of a metering completion signal or a cooling start signal and carrying out the backward travel of nozzle while the time or a counter is working when the hydraulic force in a movable cylinder becomes the pressure set in a pressure switch. CONSTITUTION:When the injection from a nozzle 2 into a mold cavity is completed and the metering for the following molding cycle is also completed, or when the cooling of a resin material filled in the mold cavity is started, a signal (a) is received by a control device 8 and a nozzle retreat start signal (b) works on a electromagnetic selector valve 6, and the nozzle retreat side of a movable cylinder 5 is raised up by the pressure shown in the drawing (A). When the pressure reaches the preset nozzle retreat pressure P, the pressure P is sensed by a pressure switch 9 and a timer 10 is worked by a sensing signal (c). As shown in the drawing (B), the retreat of the nozzle is started to move at the starting point A of the timer 10 which means that the pressure of the movable cylinder 5 reaches the nozzle retreat pressure P, and retreat is carried out by the set time T of the timer 10 to produce the distance L which is constant all the time.

Title: Ink feeder of ink jet printer
Inventor: YAMAMOTO YOUICHI
IPC: B41J2/165
Filed: 1977-11-18
Abstract: PURPOSE:To prevent clogging of ink jet nozzles owing to the insoluble precipitate deposited by metal ions by providing a filter device composed of chelate resins which absorb metal ions in the specified position of the ink feed line. CONSTITUTION:A chelate resin filter device is removably provided between the air trap 3 and pump 4 in the feed line of the ink feeder. Since the metal ions in the ink having been fed from the air trap 3 are absorbed in chelate resins 13, the ink perfectly absent of metal ions is fed to the pump 4. Hence, deposition of carbonate, etc. owing to the metal ions does not occur in a jet nozzle 9. Further this filter device is removable from the lead-out pipes 15, 16 of the air trap and pump by means of a cap nut 12, thereby permitting easy exchanging of the chelate resins 13. In this way, clogging of the nozzle by the insoluble precipitate may be prevented.

Abstract: PURPOSE: To considerably decrease the available chlorine concn. in waste liquid and save the using amount of hypochlorous acid by admitting the hypochlorous acid washing waste liquid of maldorous gases into an alkali washing process which is a fore-process thereof.  
     CONSTITUTION: The gas 1 to be treated contg. malodorous gases is admitted into the lower part of an alkali washing tower 3, and the alkali washing liquid 4 stored in the tower bottom is sprayed to this gas from the upper part of the tower 3. The gas 3 is then subjected to gas-liquid contacting with the washing liquid 4 in a packed bed 6 so that the malodorous components are migrated to the liquid side. On the other hand, the gas out from the tower 3 is sent to the lower part of a hypochlorous acid washing tower 8. In this tower 8, the hypochlorous acid washing liquid 10 circulated by a pump 9 is sprayed from the upper part and is contacted with gas admitted from the lower part of the tower 8 in a packed bed 11, so that the malodorous materials to be oxidized are oxidized and are migrated to the liquid size. On the other hand, the hypochlorous acid washing waste liquid 12 drawn from the bottom of the tower 8 is admitted into the alkali washing liquid storage part in the bottom of the tower 3. In addition, the alkali washing waste liquid 14 drawn from the tower 3 is sent into a waste liquid neutralizing tank 15, where it is neutralized with an acid 16 supplied, after which it is released 19 from the tank 15.

Filed: 1993-05-19
Abstract: PURPOSE:To simply evaluate the contact property of a ceramic thin film formed on the surface of a metal matrix by a method wherein the center of a test piece is impacted and bent at a prescribed angle to produce cracks in the ceramic thin film and its production range is measured. CONSTITUTION:A test piece 1 on which a ceramic thin film 2 is formed is impacted within a range in which a test-piece preform is not broken down, and the contact property of the thin film 2 can be evaluated. The less the thin film 2 is exfoliated or a crack 3 is produced the better the contact property of the thin film 2 is. The bend angle of the test piece 1 is desirably 2 to 8 deg. when the test piece 1 on which the thin film 2 is formed on the blow side is used. The damaged situation of the thin film 2 in the crack production region 3 produced around the blow center 4 of the test piece 1 after a test is observed by the naked eye of by using an optical microscope, and the production range L of the crack and the interval of cracks as required are measured. The dispersion of measurements which have been repeated 10 times under individual conditions is small at 10% or lower with reference to the individual mean values.

Title: Highly water absorptive concrete placing form
Inventor: ISHIGAMI SHINOBU
IPC: E04G9/10
Filed: 1993-05-19
Abstract: PURPOSE:To provide good drainage property by using rock wool in which mineral fibers are formed in pill-shaped grains having a prescribed diameter, and by hydrolytically hardening a composition mixed with Portland cement or the like for forming a form. CONSTITUTION:A composition in which 40 to 70 parts by weight of rock wool formed by making mineral fibers into pill-shaped grains of an outside diameter of 1 to 10mm, 35 to 55 parts by weight of Portland cement, and 15 to 30 parts by weight of dolomite plaster have been mixed, is hydrolytically hardened for forming a form. Since the rock wool has fine continuous pores, it retains water absorptivity and water retentivity; and when it is mixed with Portland cement or the like, rock wool having water absorptivity is dispersed into the composition and joined thereto. When this is used as a concrete-placing form, the water content in the concrete is absorbed by the rock wool, and the quality of concrete is greatly improved, and the development of strength can be quickened. In the case of necessity, permeable reinforcements are provided to the outside surface of the form.

Title: Production of sheet separation claw for fixing roll
Inventor: MATSUDA TAMOTSU
IPC: G03G15/20
Filed: 1996-06-03
Abstract: PROBLEM TO BE SOLVED: To prevent deformation, blister or chipping when a high temp. fixing roll is used by injection-molding an all aromatic thermotropic liquid crystal polyester resin in such a manner that the resin flows toward the top end of a separation claw. SOLUTION: The all aromatic thermotropic liquid crystal polyester resin is molded by injection in such a manner that the resin flows toward the top end of a separation paw 1. The all aromatic thermotropic liquid crystal polyester resin has such feature that it can be self-reinforced by the orientation of fibrous crystalline structure in the flowing direction, and especially the resin has excellent self-reinforcing effect at high temp. Thereby, thermal deformation or chipping of the separation claw 1 are hardly caused. Since the resin has low absorption, blister by heat is hardly caused at high temp. As for the all aromatic thermotropic liquid crystal polyester resin, for example, a polyester produced from p-oxybenzoic acid, 4, 4'-dihydroxydiphenyl and terephthalic acid, or a polyester produced by copolymn. of p-oxybenzoic acid and oxynaphthoic acid can be used.
