Title: Sheetlike sorptive body having regenerating function and activating function and laminate for sorption
Inventor: KUMA TOSHIMI
IPC: B01D53/04
Filed: 1993-03-26
Abstract: PURPOSE:To rapidly desorb adsorbed matter, to shorten the time required to regenerate an adsorptive body and to increase the efficiency of regeneration by impregnating and fixing an adsorbent into the inside and on the surface of a sheet with a built-in heating element or chemically synthesizing and fixing an adsorbent, connecting terminals to both ends of the heating element and carrying out regeneration or activation by resistance heating. CONSTITUTION:A heating element 2a such as a heating fine wire is built in a sheet, preferably a low density sheet 1 based on inorg. fibers, an adsorbent or absorbent is fixed on the sheet 1 and the sheet 1 is allowed to heat by supplying electric current to the heating element 2a to enable desorption and regeneration. Zeolite, silica gel, alumina gel or active carbon may be used as the adsorbent and it is impregnated and fixed with an inorg. binder. Since the resulting adsorptive body can directly be heated from the inside by the heating element 2a, adsorbed matter is rapidly desorbed and the time required to regenerate the adsorptive body can be shortened.

Abstract: PURPOSE:To smooth speed change at the time of stoppage and to reduce the time base fluctuation of a reproducing signal, by generating a reverse torque signal for braking in several number of times at the time of applying stoppage control on a motor for driving a recording medium. CONSTITUTION:When a capstan motor 3 is rotated at a stationary speed by the control of a servo control signal generating device 1 and a decelerating brake signal is outputted from a timing generation circuit 6 to a capstan motor drive circuit 2, the motor starts to decelerate the speed steely.

Afterwards, the circuit 6 outputs the decelerating brake signal again at a prescribed timing. By repeating such operation for several times, a decelerating operation can be smoothed, and the change of the time base fluctuation can be reduced.

Abstract: PURPOSE:To be applicable from small to large flow rate with a small size of a valve by disposing a vertical displacement element which displaces in the axial direction of a valve rod and horizontal displacement elements at the top and bottom ends of the vertical displacement element which horizontal displacement elements displace in the direction perpendicular to the valve rod axis in a housing, and constituting those element so that they are brought into successive cooperative motion. CONSTITUTION:When a horizontal displacement element A is energized, the element A displaces in the direction of the arrow, presses against the inner wall of a guide bore 9a, and is secured. When a vertical displacement element B is energized, it lowers an element C in the direction of the blank arrow. When the horizontal displacement element C is energized, it is secured at the lowered position against the guide bore 9a.

The element A is then actuated again to repeat the cooperative motion in succession to move the elements downward. Because the actuator 12 is moved up and down as described above, a wide range of flow rate control is possible with a single valve with an increased stroke.
