摘要:
The wireless sensor adds identification information peculiar to respective sensor modules to detection data of vibration, temperature, and soon, detected by the sensor modules respectively. The wireless sensor transmits the detection data with the identification information as a signal through a communication unit by radio waves. On the other hand, the management apparatus receiving the signal classifies and files the detection data on the basis of the identification information included in the signal. Then, the monitoring system is designed to make the management apparatus manage a plurality of wireless sensors attached to movable shafts of processing machines or the like.

摘要:
A rolling bearing apparatus with sensor includes a sensor unit retaining a plurality of types of sensors for detecting the status of a rolling bearing, in a single holder. The plurality of types of sensors are at least two types of sensors of a rotation speed sensor, a temperature sensor, and an acceleration sensor.
摘要:
The invention provides a solid electrolytic capacitor which comprises a capacitor element including an anode body having an anode leading member, and a dielectric coating layer, a solid electrolyte layer and a cathode leading layer which are formed successively over a surface of the anode body. The anode leading member has an anode terminal member connected thereto, the cathode leading layer has a cathode terminal member connected thereto, and the capacitor element is covered with a packaging resin portion. The cathode terminal member is connected to the cathode leading layer with current control means provided therebetween. The current control means comprises a current control layer reversibly increasable in electrical resistance with overcurrent or excessive heat, and a pair of electrode members each in the form of a plate or foil and having the current control layer sandwiched therebetween. The electrode members are joined to the cathode leading layer and the cathode terminal member, respectively.
