摘要： This torque limiter is configured from a ring body and a spring-form part provided in the ring body. The ring body comprises a band-form metal plate and is bent approximately into a C-shape along the circumferential direction of a motor shaft and a lock holder. The spring-form part is formed so as to be capable of radial elastic deformation. The spring-form part is configured from main protrusions arranged in a compressed state between the motor shaft and the lock holder, and from sub-protrusions arranged in a non-compressed state. Further, grease is stored in a part or all of the concavities formed by the main protrusions and the sub-protrusions.

摘要： The voltage output terminals of a semiconductor integrated circuit are connected to the first ends of resistors while the second ends of the resistors are connected to a common signal line. Taking advantage that the potential of the signal line presents the mean voltage value of the voltages output from all the voltage output terminals, the deviation of the potential at each voltage output terminal from the mean value and the difference of this mean value from the ideal value are determined, whereby the suitability of the output voltage from each of the output terminals is examined.

摘要： An electroless plating deposition speed measuring apparatus is provided with a sensor having an electrode couple whose pair of electrodes are opposed to each other and a sensor drive circuit that cyclically applies voltage to the electrode couple to measure a polarization resistance between the pair of electrodes of the electrode couple. Measuring data from the sensor drive circuit are supplied to a processing circuit. The processing circuit computes and processes the measuring data to find the plating deposition speed. Data of the plating deposition speed from the processing circuit are supplied to a display circuit to display the data of the plating deposition speed. In a preferred embodiment, each of the pair of electrodes of the electrode couple has a conductor and a non-conductor, wherein the surfaces of the conductors and the non-conductors of the respective electrodes are arranged in facing and opposite relation to each other. Each of the conductors is made of a noble-metal material, such as copper, gold, platinum, palladium or the like, while each of the non-conductors is made of an alkaliproof non-conductive material, such as epoxy resin, epoxy resin of a glass base material, or the like.
