Title: Treatment of fly ash
Inventor: SHIMAOKA TAKAYUKI
IPC: B09B3/00
Filed: 1999-05-14
Abstract: PROBLEM TO BE SOLVED: To suppress the elution of heavy metals in fly ash to an environmental reference value or below by adding one or >=2 of sulfate, aluminum-containing material and alkaline material to the fly ash and water, kneading both and blowing carbon dioxide into the mixture. SOLUTION: One or >=2 of the sulfate, aluminum-containing material and alkaline material are added to the fly ash and water and these are kneaded. The carbon dioxide is then blown to this mixture. The carbon dioxide is so blown to the kneaded matter in such a manner that its pH value attains <=1O. More preferably the pH value is confined to <=9. Not only the pure carbon dioxide but the carbon dioxide in exhaust gases of an incineration furnace, etc., as well are used as the carbon dioxide for blowing. Potassium sulfate (gypsum), sodium sulfate, etc., are used as the sulfate. Aluminum oxide, aluminum hydroxide, etc., are used as the aluminum oxide. While the alkaline material is not particularly restricted, various kinds of Portland cement essentially consisting of calcium oxide and mixed cement containing these are also used in addition to slaked lime and quicklime.

Filed: 1978-10-31
Abstract: PURPOSE: To enhance the seal property between the title corner seal and an apex seal at the time of a temp. rise of an engine by extensibly press.-contacting the corner seal, at all times, made of sintered Fe alloy of a specified compsn. contg. Ni, Cu and C to the inside of a groove for the corner seal cut in a rotor.  
     CONSTITUTION: Each corner seal 1 is made of high thermal expansion sintered alloy consisting of Ni 8W25%, Cu 3.5W10%, C≤2.0% and the balance Fe. This alloy has a thermal expansion coefficient higher than that of rotor 3 and a density of 5.5W6.8g/cm 3 . At the time of a temp. rise of an engine, groove 4 for seal 1 extends owing to thermal expansion of rotor 3, yet a gas leak is prevented by expanding seal 1 in a direction for narrowing space S between seal 1 and apex seal fixing groove 1a and controlling the extension quantity of space S to a quantity equal to or smaller than the thermal expansion quantity of seal 1. By raising the density of seal 1 wear resistance is provided to seal 1, and the durability of seal 1 is enhanced.

IPC: H01J9/48
Filed: 1984-07-02
Abstract: PURPOSE:To enable incandescent-type fluorescent lamps of various types to be automatically assembled by using a switching mechanism for maintaining the center and height of lamps with different shapes and sizes. CONSTITUTION:The entire body of a jig for feeding an incandescent-type fluorescent lamp is slidden on a rail 7 by pulling a chain 3. When an incandescent-type fluorescent lamp 9 with a different diameter is mounted on this jig, a slide plate 13 is slidden by half of the change in lamp diameter before the slide plate 13 is again fixed to a plate 14 by inserting a lock pin 11. This process is performed without changing the center of the lamp 9. When an incandescent-type fluorescent lamp 9 with a different height is mounted on this jig, a lamp receiver 10 is extracted and the position of a holder 19 with a step is changed by the change in lamp height. The upper surface of the holder 19 is provided with several circular grooves which have different depths and can be attached to the lamp receiver 10. Consequently, the height of the upper surface of the lamp 9 is not changed.

Filed: 1985-06-20
Abstract: PURPOSE:To make fast reproduction stable and accurate by controlling a track read-in linear speed along tracks among relative running speeds of a rotary head for a magnetic tape in normal reproduction and fast reproduction to a constant speed. CONSTITUTION:Playback signals of both heads are inputted to a detection part 2 through an input terminal 1.

Consequently, a speed along tracks among relative running speeds of the head for the tape in the normal reproduction and fast reproduction, i.e. track read-in linear speed is detected directly. Then, the rotating speed of the head or the running speed of the tape is controlled by a servocontrol part 10 so that said detected speed is constant, thereby making the fast reproduction stable and accurate.
