    摘要: Disclosed herein is a method and sensor for easily detecting the thermal history (or the change in state by heat) of a specimen. The sensor is made up of a pair of electrodes 1, 1, a diffusion layer 2 of insulating material disposed between the electrodes, and an electrically conductive metal 3. The electrodes are electrically isolated from each other in the beginning. As the sensor experiences heat history, the electrically conductive metal diffuses into the diffusion layer 2, thereby changing the resistance of the diffusion layer. When in use, the sensor is placed in or near the atmosphere to which the specimen is exposed. In response to the change of the specimen by heat, the electrically conductive metal 3 diffuses into the diffusion layer 2 to such an extent that the electrical resistance across the electrodes extremely decreases after a certain period of time. Thus it is possible to detect the deterioration or life of the specimen by monitoring the change in electrical resistance of the sensor.

    摘要: A data communication system which includes a data distributor, a communication station and a plurality of front-end-processors. These front-end-processors are connected with a computer through a common bus. The distributor distributes the data received by the station to one available front-end-processor, which preprocesses the received data, and transfers the pre-processed data to the computer through the bus. By operating the front-end-processors in parallel with respect to successively received packets of data, the processing speed of the system is increased.

    摘要: An infrared sensor switch of the invention comprises an infrared sensor with a detection range, and a controller that uses the sensor to try to detect whether or not a person is present in the detection range and controls an ON or OFF state of a corresponding load unit based on each detection result obtained from the sensor. The switch further comprises a sensor block comprising the sensor, and a housing that is mounted in a wall and retains the block so that the center axis of the detection range can be rotated about a horizontal axis and as well as rotated up to at least 40 degrees downward from a forward direction of 0 degrees.
