Title: Abnormality detector of shaft twist detecting apparatus
Inventor: HONMA NAOKI
IPC: G01M99/00
Filed: 1983-02-10
Abstract: PURPOSE:To automatically detect abnromality such as the change of circuit constant, by periodically operating a shaft twist detector by a dummy signal while comparing the limit value of the obtained signal with set real limit value. CONSTITUTION:In measuring shaft twist, a switch 5 is set to an (a)-side and the shaft twist signal (c) from a sensor 3 and a converter 6 is outputted to the outside through a terminal 12. In investigating the presence or absence of abnormality, the switch 5 is changed over to a signal (b)-side and the converter 6 is operated by the dummy signal (b) of a signal generator 4 while output (c) is inputted to a memory apparatus 8 through a imit value detector 7. The constant set to a setting device 9 imparts the dummy signal (b) to the converter 6 during normal operation and is the limit value obtained by the limit value detector 7. The content of the memory apparatus 8 and the content of the setting device 9 are successively compared by a comparator and the change of the circuit constant of the converter 6 can be detected.

Title: Rubber sheet
Inventor: MAYUMI KATSUMI
IPC: B29L7/00
Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To realize the favorable blocking resistance and adhesion of a rubber sheet by a method wherein at least one of a front and a rear surfaces is made into a roughened surface equipped with a large number of small projections so as to have a specified surface roughness. SOLUTION: At least one side of a rubber sheet is made into a roughened surface equipped with a large number of small projections so as to have a surface roughness Rmax of 50-300μm. This manufacturing method is to vulcanize in piles of desired matrices or continuously one side or both the sides of unvulcanized rubber sheets or of an unvulcanized sheet. When a continuos vulcanizer is employed, the surface itself of a heated roll, the surface of which is worked by a shot blasting method so as to have a desired surface roughness, is employed as a matrix so as to feed the unvulcanized rubber sheet between a steel belt and the heated roll in order to continuously vulcanize the rubber sheet under the condition that the surface unevenness of the heated roller is transferred to the rubber sheet. As a result, no hard separation develops under the condition that a pressure is applied to the piled-up rubber sheets. In addition, when the rubber sheets are connected to each other through an adhesive, the separation strength between bond areas becomes stronger. As the rubber sheet, a sheet made of natural rubber or of various synthetic rubbers is employed.

Title: Manufacture of high nitrile resin sheet
Inventor: UEKI TORU
IPC: B29K55/00
Filed: 1986-02-03
Abstract: PURPOSE:To obtain a manufacture of a sheet which maintains gas barrier properties and transparency and is superior in surface smoothness, by keeping high nitrile resin, which is supplied to a calender, kneaded beforehand. CONSTITUTION:The titled method is a manufacture of a sheet formed by making use of high nitrile resin, which has been kneaded beforehand,at the time of molding by making use of a calender. The high nitrile resin used herein is a copolymer having unsaturated nitrile such as acrylonitrile or methacrylonitrile as the main constituents and containing 50wt% or more of the unsaturated nitrile. High nitrile resin is kneaded by making use of a heating kneader. It is desirable to perform this kneading under a temperature range of 180 deg.C-220 deg.C normally. In other words, when the temperature is less than 180 deg.C, it is not desirable as torque increases at the time of the kneading and when the temperature is more than 220 deg.C, it is not desirable as the high nitrile resin pyrolyzes. Although the time necessary for the kneading vary according to a kneading machine and kneading temperature, they are normally 1-60min.
