Filed: 1983-08-31
Abstract: PURPOSE:To reproduce a chrominance signal whose frequency amplitude characteristic and group delay characteristic are good, by eliminating an unnecessary side band of a signal converted to a high band by a frequency converting carrier, by a comb line filter. CONSTITUTION:A signal reproduced by a video head 1 is inputted to a regenerative, pre-amplifying circuit 3 through a rotary tramsformer 2.

For temperature estimating operation, estimation of heating and cooling temperature of each pixel position when cross talk is not considered, is firstly performed, and this estimated temperature value is stored in a heating and cooling line buffer 28. This one line content estimated temperature value is averaged between adjacent pixels, and the estimated temperature value containing the cross talk is stored in a cross talk line buffer 42. Since the obtained estimated temperature value is increment from the temperature of the heat slinger, output is performed by adding temperature of each position.

Title: Rubber roller used in copying machine or the like
Inventor: ISHIHARA NORIYUKI
IPC: G03G15/00
Filed: 1979-12-10
Abstract: PURPOSE: To prevent the rubber layer of the titled rubber roller from being peeled off the edge faces of the core roller by making the diameter of rubber layer sections, smaller than that of other part, each having a predetermined distance from one edge of the layer in the longitudinal direction of the roller.  
     CONSTITUTION: Silicone rubber layer 2 is formed around metal core roller 1 by hot vulcanization. The diameter of layer 2 in distance (l) between a position near both edge faces and face 3 is gradually reduced toward each edge face 3 and made smaller than the diameter of other part, that is, a part contacting with a support. As a result, the outside of layer 2 in distance (l) does not contact with an opposite roller of contacts with it under a slight pressure as compared to the pressure which is received by other inside part, thereby reducing the expansive deformation pressure acting on both edge faces. The effective length of (l) is obtd. according to equation I [where P is pressure (g/mm) per mm of the surface of rubber layer 2, t is thickness (mm) of layer 2 and H is JIS hardness (degree) of the circumferential surface of layer 2]. Thus, layer 2 can be prevented from being peeled off the edge faces of core roller 1.

Abstract: PURPOSE:To make nearly almost constant the speed of revolution of an electric machine tool to its torque by a method wherein a switching element for phase control connected in series to a power circuit is controlled according to the value of the current sent to the tool. CONSTITUTION:An output of a commercial power supply input unit 1 is supplied to an electric machine tool 2 via a thyristor 4, a current detecting element 5 and a power supply connection unit 3. A continuity angle control circuit 6 inputs the voltage between both the ends of the current detecting element 5 through a large current limiting circuit 25 to control the continuity angle of the thyristor 4, so that the tool 2 may revolve at a nearly almost constant speed. A circuit 14 for detecting the damage of the element and another circuit 15 for detecting an abnormal current allow a pseudo-leak generating circuit 13 to operate when they have detected the abnormal current, making a leak breaker 12 operate. By so doing, it is possible to maintain the speed of revolution of the motor-operated tool almost constantly without the necessity of a means for detecting the speed of revolution.
