Title: Liquid setting promoter for hydraulic binder and production and usage of the promoter
Inventor: MATSUURA SHIGERU
IPC: C04B22/08
Filed: 1999-04-26
Abstract: PROBLEM TO BE SOLVED: To obtain the subject promoter having good preservation stability and setting promotive performance without getting solidified even after stored for a given period by wet grinding of a mixture of a component I as an aqueous solution or aqueous suspension of aluminum sulfate and a component II consisting of at least one kind of calcium aluminate-based compound powder to react the component II with water. SOLUTION: The component II in this promoter is CA, C2A, C3A, C12A7, CA2, CA6, C4AF, C2ASiO2, C3A3X, C4A3X, or a mixture thereof. In this liquid setting promoter, the component II is entirely reacted with water into dihydrate gypsum and noncrystalline aluminum hydroxide by wet grinding, therefore this promoter does not get solidified through liquid deterioration even after stored for a long period of time. The component II accounts for <=40 wt.%, pref. 15-40 wt.%, on a dry solid basis, of the total of the components I and II. In this promoter in the form of an aqueous solution, it is preferable that the pH is <=4 and the alkali component content is 0.5-5 wt.% calculated as the corresponding alkali metal oxide(s).

IPC: H01H21/36
Filed: 1989-05-10
Abstract: PURPOSE:To make it possible to continuously use a switch by thinning it and increase a set rotary stroke width of an operating lever by providing a second plunger to pushingly drive a push button portion of a basic switch and an auxiliary coil spring to absorb the shaft driving of a first plunger from the time when the push button portion is pushed in. CONSTITUTION:When a detected hits against a roller 15 and an operating lever 14 rotates clockwise or counterclockwise, the second plunger 18 responds thereto with the result that a push button portion 5a of a basic switch 5 is pushed in and the basic switch 5 is turned on. When the operating lever 14 further rotates, an auxiliary coil spring 21 is further compressedly deformed, and the second plunger 18 and a holding plate 20 are relatively displaced so that the shaft drive of the first plunger 8 is absorbed. As the operating lever 14 is arrangedly installed within the thickness W of a switch case 1, if is possible to continuously connect a plurality of switches as thin ones. Thereby, it is possible to use continuously connected switches by thinning them so that the rotary stroke of the operating lever can be widened; in other words, it is possible to certainly detect a detected with a large movement.

Title: Switch
Inventor: INOUE RYUICHI
IPC: H01H31/28
Filed: 1996-05-14
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of the impossibility of opening-closing operation without increasing open circuit operation force by arranging a contact pressure reducing means to reduce contact pressure of movable contactors to a fixed contactor at open circuit operation starting time of the movable contactors. SOLUTION: When closed circuit operation is performed from a closed circuit, an insulating rod 9 is driven rightward, and a lever 21 connected to this is rotated in the anticlockwise direction with a bolt 11 of a second contact pressing means 8 as a shaft. Therefore, inclined faces 21a and 21b act so as to expand an interval between plate members 6a and 6b of a pair of movable contactors 6, and in a condition where contact pressure is reduced, tip parts 6c of the movable contactors 6 slidingly move on a fixed contactor 4a, and separate from the fixed contactor 4a thereafter.  In this case, reduction in contact force of the second contact pressing means 8 by the expansion of an interval between the movable contactors 6 can be attained by small operation force by the principle of the lever, and even when a friction coefficient between the movable contactors 6 and the fixed contactor 4a becomes high at closed circuit time, separating operation can be smoothly started by small operation force.

Abstract: PROBLEM TO BE SOLVED: To make opening of an inner stopper with a holding member easy by a method wherein an arc-shaped holding member is provided integrally at a side wall part with a pair of separated connecting parts that are smooth at their inside, and the holding member is provided in extension at the side of a circumference that is longer than the other out of the circumferences between the connecting parts. SOLUTION: For an inner stopper, an arc-shaped holding member 4 is provided integrally at a side wall part 2 with a pair of separated connecting parts 5 that are smooth at their inside, and the holding member 4 is made to extend to the side of a circumference a that is longer than the other out of the circumferences a and b between the the connecting parts 5. The connecting structure for the holding member 4 and the connecting parts 5 is such that each of the connecting parts 5 is made thicker in thickness as compared with the side wall part 2 and the holding member 4 and made hardly expandable when the holding member 4 is pulled, and thereby a tensile force is easily transmitted to the side wall part 2. Thereby, opening of the inner stopper by the holding member 4 becomes easy and progressive smoothly, and seal break can be made, preceding opening of the stopper.

Abstract: PURPOSE:To maintain a sufficient yield of ozone and to prevent an accident in a generating apparatus for ozone by measuring the temp. of an adsorbent in an adsorption tower of the apparatus to detect a rise in the dew point of air and by giving a warning. CONSTITUTION:Starting material air to be fed to an ozonizer is passed through one of 2 adsorption towers. While moisture is being adsorbed in one of the towers, an adsorbent is regenerated in the other. Temp. switches 6h, 6i are attached to the adsorption towers 6a, 6b, respectively tomeasure the temp. of the adsorbent at the end of a heating stage, and when the temp. is reduced to below the set temp. value, a warning signal is sent to the outside. At this time, the relation between the temp. of the adsorbent at the end of the heating stage and the dew point of dry air in an adsorption stage is established beforehand, and it is used as the warning setting value. A control circuit which stops the generation of ozone and the operation of the ozonizer as soon as it receives the warning signal is installed. Thus, a simple and inexpensive generating apparatus for ozone can be constructed without installing a dew indicator.
