IPC: G01H13/00
Filed: 1995-06-05
Abstract: PURPOSE: To measure the tension of a belt stretched between the pulleys of an engine with high accuracy and reproducibility without being influenced by the excited state of the belt by detecting the resonance point of the belt while the belt is excited from the outside by continuously changing the exciting frequency and calculating the tension of the belt by using the exciting frequency at the resonance point as the characteristic frequency of the belt.

Filed: 1993-06-10
Abstract: PURPOSE:To obtain a semiconductor device including an epitaxial layer of high surge breakdown voltage by forming an epitaxial layer having a specific thickness on a semiconductor substrate in such a manner it incorporates another epitaxial layer of the opposite conductivity type. CONSTITUTION:A phosphorus-doped N<->-type epitaxial layer 2 having a thickness of several tens mum to 200mum is formed on an antimony-doped N-type silicon substrate 1. Then, after forming a p-type layer 3 of the opposite conductivity by diffusing such an impurity as boron, etc., in the layer 2, an insulating film 4 composed of SiO2 is formed on the surface of the layer 2 and electrodes 5 and 6 are provided. Since the layer 2 is formed to a remarkably large thickness as compared with the conventional example in such a way, the resistance of the layer 2 is increased. Therefore, the layer 2 is not broken down by reverse power of about 15W, but the surge breaking down voltage of the layer 2 is increased to 55W.
