Filed: 1996-05-28
Abstract: PROBLEM TO BE SOLVED: To obtain paste containing clay as a main component which is of high concentration and homogeneous and has good dispersibility by heat- concentrating aqueous dispersion liquid having a specified content of clay. SOLUTION: A mixture in which 10.5-25.0wt.% of clay such as montmorillonite is dispersed in water is concentrated by heating at 100 deg.C or below while stirring slowly to prevent kneading effect to obtain paste containing clay as a main component which is homogeneous and has good dispersibility.

Filed: 1993-06-04
Abstract: PURPOSE:To improve the characteristic of hot water feed when a shower bath and the like are intermittently used in resuming the operation of a hot water feeder and improve convenience for use of the same. CONSTITUTION:A hot water feeder comprises a water passage providing a water flow rate detector 2 and a gas passage providing a solenoid valve 5, a proportioning valve 6, a fan 7, an ignitor 8 and a burner 9. Furthermore, when the operation of the hot water feeder is resumed, a controller 10 increases a revolving speed of the fan 7 to the number of revolutions of the fan at the time of maximum combustion and then controls it to the number of revolutions required for ignition when the solenoid valve 5 is opened. By this method, the number of revolutions of the fan can be reduced so as not to cause any explosive sound at the time of ignition and so as not to cause any blowout and noise after the stopping of operation. Accordingly, a temperature drop at the time of the resumption of operation can be minimized, and large fluctuations of a temperature of hot water to be supplied can be prevented.

Filed: 1982-08-03
Abstract: PURPOSE:To decrease the outside diameter of a lens barrel and to attain smooth operation by the constitution wherein a moving frame is moved together with an operation ring in an optical axis direction and rotational and rectilinear motion is induced in front and rear zooming frames by the movement of the moving frame. CONSTITUTION:If an operational ring is moved forward from the short focal position shown in (a), a moving frame 2 formed in one body thereto via a helicoid cylinder advances together with the 4th lens group in an arrow direction as its pin 2c is guided by the groove 1c of a stationary lens barrel 1. Therefore, the overlap position of the groove 1a of the barrel 1 and the groove 2a of the frame 2 and the groove 6a of the zooming cylinder in a rear part as well as the overlap position of the groove 1b of the barrel 1 and the groove 2b of the frame 2 displace pins 6b, 7a to the position (b). Thus the 3rd lens group of the zooming frame in a rear part moves forward and the 2nd lens group of the zooming frame in a front part moves backward, so that the frames are set in a long focal position. Thus the outside diameter of the lens barrel is reduced and the operation is smoothed.
