Title: Clutch plate
Inventor: NAKANISHI YUTAKA
IPC: F16D13/62
Filed: 1993-12-28
Abstract: PURPOSE:To instantaneously transmit and interrupt power by forming a plurality of scattered projections each having height smaller than thickness of a rubber plate, which projections are made of resin having hardness compared to rubber on a surface of the rubber plate. CONSTITUTION:A rubber plate 1 having thickness of 1mm is cured by NBR having Shore A hardness of 50 degrees. Epoxy liquid resin is mounted semi- spherically on the surface of the rubber plate 1 by 0.5mm, and heated to form a projection 2. When the thus formed clutch plate is pressed against a flat reception part, the resin projection 2 enters the rubber plate 1 having small hardness. An end of the projection 2 has the same level of the surface of the rubber plate 1. The clutch plate is in close contact with the flat reception part. Sufficient frictional resistance is generated by the viscosity and elasticity of the rubber plate 1. Force such as rotation of a driving part is transmitted to the reception side. When the clutch plate is cut, compression of the driving part is abruptly eliminated. Compression of the rubber plate which is pressurized by the projections 2 is released. Frictional resistance is eliminated, and power transmission is instantaneously stopped.

Title: Correlation detector and correlation detection method
Inventor: USUI TAKASHI
IPC: H04J11/00
Filed: 1997-12-18
Abstract: PROBLEM TO BE SOLVED: To allow a correlation detector to accurately detect a prescribed code series from an input signal with a simple configuration. SOLUTION: An amplitude of an input signal (S40) is limited to a prescribed value and given to a matched filter means 71 so as to prevent that the matched filter outputs being in mistake a correlation value with a high signal level, even through the value is not a code series of a detection object. Thus, only the code series of the detection object is detected accurately and then the correlation detector is realized with a simple configuration, where a prescribed code series is detected from the input signal accurately.
