Title: Switching element testing apparatus
Inventor: UEDA SHINJI
IPC: G01R31/26
Filed: 1983-05-16
Abstract: PURPOSE:To make it possible to perform the ON-testing of a switching element without actually operating a relay, by selecting timing for applying a test pulse in synchronous relation to AC voltage applied to the switching element. CONSTITUTION:Voltage applied to a switching element is converted to a rectangular wave by a detection circuit 7 to be inputted to a monostable multivibrator 8a which is, in turn, triggered by the falling of the rectangular wave 7a while a monostable multivibrator 8b is operated to output a signal 8c. When an enable signal TEN is one-level, the signal 8c is allowed to pass and sent out as a signal 9a. This signal 9a is applied to the gate of the switching element 3 through an OR gate 1 and a trigger circuit 3 and the switching element 3 is turned ON from the time when the signal 8c is generated to the time when the voltage of an AC power source 6 reaches zero. The phase of the signal 8c can be arbitrarily set by adjusting the pulse width of the monostable multivibrator 8a. Test pulse generating timing can be arbitrarily made synchronous to the AC power source and the function of the switching element can be tested without operating a relay.

Title: Rubber roller
Inventor: NOMA HIDEYUKI
IPC: B41J11/02
Filed: 1984-04-28
Abstract: PURPOSE:To prevent metallic sound from being generated due to impacts and corrosion resistance from being deteriorated due to rusting, by a method wherein a shaft obtained by molding a bulk molding compound (BMC) around a metallic core is covered by a rubber metal. CONSTITUTION:A BMC obtained by incorporating a reinforcing material into a blended resin prepared by dispersely mixing a thermoplastic resin into a matrix of an unsaturated polyester resin is moded around the metallic core 4 to form the shaft 5, which is then covered by a rubber material. The sound generated by an impact on the molded BMC is in a low frequency region, and generation of a standing wave in the shaft body can be prevented by setting the length of the body to be relatively small, so that harsh metallic sound can be prevented from being generated, and the musical scale and volume of the impact sound can be lowered. In addition, since the BMC also has excellent corrosion resistance, the rubber roller obtained by covering by the rubber the shaft formed by molding BMC around the metallic core consisting of a rod of a metal such as iron and aluminum is light in weight and is free of danger of corrosion due to rusting.
