IPC: C08F20/00
Filed: 1987-04-28
Abstract: PURPOSE:To obtain a cement composition capable of readily adding to concrete, slightly forming undissolved lump of flour and capable of kneading with a simple mixer and improve the workability, by blending a readily flowable polymer dispersion as a thickener to a cement. CONSTITUTION:A homopolymer of sodium acrylate, aluminum sulfate, sodium sulfate and ion exchange water are charged into a separable flask having five mouths and equipped with stirrer, thermometer, reflux cooling tube and nitrogen inlet tube and dissolved and then acrylamide is charged thereto, heated and nitrogen-substituted. An aqueous ammonium persulfate solution and sodium hydrogensulfite solution are added thereto and polymerized while stirring to afford a polymer having fine particle dispersed in the aqueous salt solution. The polymer dispersion is blended as a thickener to a cement to provide the viscous cement composition. The composition has good workability, because the composition is a dispersion having low viscosity and good flowability and a conventional quantitative pump can be used thereby.

Abstract: PURPOSE:To enable prolonged use in a hot and humid environment and a highly accurate measurement in a wide-range of humidity area, by applying an output of an oscillation circuit to a voltage dividing circuit composed of a resistor and a temperature sensor to compare an output voltage of the voltage dividing circuit with a reference voltage. CONSTITUTION:Carbon particles are dispersed into a sol produced by hydrolysis of silicon alkoxide and the sol is gelatinized and dried and sintered to form a humidity sensor 1. An output A of an oscillation circuit 2 is connected to a CK input of a D-FF3 and two analog switches 4 are driven by an output thereof to switch a direction of connecting the sensor 1. An output of a circuit 3 is applied to a voltage dividing circuit comprising the sensor 1 and a reference resistance Rr. An output voltage B of the voltage dividing circuit is compared with a reference voltage C by a comparator 5 to make an output D as oscillation sound output using an oscillation circuit 6, a transistor 7 and a speaker 8. Thus, as the direction of connecting the sensor 1 is switched by a cycle of the output of the oscillation circuit, electrolysis can be avoided thereby minimizing changes in and degrading of characteristic even in a prolonged use.

Title: Device for varying sectional area of stack top portion
Inventor: KOSHIHARA TOSHIO
IPC: F23L17/02
Filed: 1986-05-08
Abstract: PURPOSE:To automatically adjust an area where an exhaust gas passes to set the flow speed of the gas to a substantially predetermined value thereby to positively prevent a whistling phenomenon and a down washing phenomenon from occurring by suspending a cone end of which is formed in a sectional rhombic shape by means of a spring fixedly mounted on a smoothing plate and the large-diameter portion of which is larger than the diameter of the smoothing plate disposed at the innermost part, between the smoothing plate and the stack top part. CONSTITUTION:A cone 6 which has kept balance because there is no exhaust gas and a downward force is substantially zero is pushed upward by the pressure of the passing exhaust gas, and the spring 7 contracts and the cone 6 keeps balance with the pressure of the exhaust gas in a floating state. The exhaust gas passes through a cylindrical portion formed by a straight nozzle 3 and a second smoothing plate 5, and then is smoothed and discharged. At this time, the area where the exhaust gas passes assumes an opening area a4. This is because the cone 6 moves up and down depending on the amount of the exhaust gas. That is, when the amount of the exhaust gas is large, the cone 6 is pushed up to increase the opening area a4, whereas, when the amount of the exhaust gas is small, the cone 6 falls to decrease the opening area a4. Therefore, the flow speed at which the exhaust gas passes the cone 6 becomes substantially constant.
