Title: Automatic equalizer
Inventor: IGA HIROYUKI
IPC: H03H15/00
Filed: 1983-05-17
Abstract: PURPOSE:To decrease the abnormal operation such as divergence and also residual distortion by providing always a required minimum value of leakage to a tap gain correcting control independently of the distorting state of an input signal. CONSTITUTION:A ghost component of a television set present at, e.g., input terminal 10 is eliminated by setting properly the tap gain of a transversal filter 20. The operation of correlation is attained by reading the content of an input waveform memory 41 and an error waveform memory 46 but the tap gain correcting control might be diverged because of the effect of the frequency characteristic of the transversal filter. If this divergence is not detected by an abnormal operation detecting circuit 63, its value is read from a tap gain memory 48, a leakage provision circuit 54 brings a main tape having the maximum tap gain to a predetermined value and provides leakage in the direction that the other tap is zeroed. When the divergence is detected, switches 60, 61 are changed over and the tap gain at divergence is reset by being shrinked proportionally. Then, the leakage amount is increased so as to prevent the divergence.

Title: Pneumatic slip coupling
Inventor: OKAMOTO MITSUO
IPC: F16D43/284
Filed: 1989-04-05
Abstract: PURPOSE:To operate a slip coupling with the same characteristic even in a severe temperature condition by converting differential rotation being produced between a shaft and an outer cylinder into reciprocating motion of a piston through a cylindrical cam mechanism and a plate cam, producing compressed air, and letting this compressed air act on a pressure piston of a multiple disk clutch. CONSTITUTION:When turning effort is added to an input shaft 1 in a state of load being imposed on an output shaft (order cylinder), differential motion starts between the shaft 1 and the outer cylinder 2. This differential motion is converted into reciprocating motion of a piston 7 by a cylindrical cam 6 and a cam roller 5, starting a compressive action of air. The compressed air is led to a cylinder 14 from a cylinder 9a, and it acts on a piston 15, turning to each pressure-sticking force of friction plates 3 and 4 of a multiple disk clutch. This pressure-sticking force produces frictional force, and thereby turning effort at the side of the input shaft 1 is transmitted to the side of an output shaft 10 as starting a slip. In differential speed between both input and output sides is large enough, reciprocation of the piston 7 comes furiously and discharge of the compressed air grows large, pressure goes high and the frictional force enlarges, thus transfer torque increases as well.

Title: Target and three-dimensional position and attitude measuring system using same
Inventor: YAMADA NAOSHI
IPC: G01S17/875
Filed: 1990-03-29
Abstract: PURPOSE:To make it possible to remarkably improve measuring accuracy by providing four or more marks and a spherical-surface reflector on the same plane of a target for measuring attitude. CONSTITUTION:Corner-cube reflectors 2a - 2d at four points are attached on a substrate 1 of a target 9, and a spherical-surface reflector 3 whose center of curvature is located at a point 7 is formed. When light from a light source 14 is projected on the refelctor 3, the light is refelcted from reflectors 2a and 2c. The images of the reflected light are formed on a solid-state image sensing element 18 through a lens group 17. Bright spots 20a and 20c are generated. The bright spots are also generated on the image sensing element 18 by the reflected light beams from other reflectors 2b and 2d and the center of the concave mirror 3. Thus, the total of five bright spots of 21 and 20a - 20d are obtained. The three-dimensional attitude is measured by using the bright spots. Thus, conventional projections are eliminated, the concealment of marks is eliminated and the risk in collision in docking is avoided.
