Title: Estimation method for failure of power semiconductor element due to thermal stress
Inventor: MATSUBARA SHUNSUKE
IPC: G01R31/26
Filed: 1996-07-24
Abstract: PROBLEM TO BE SOLVED: To obtain an estimation method in which the failure of a power semiconductor element due to a thermal stress is estimated by a method wherein, in a temperature change on the basis of a change in the current of the power semiconductor element, a prescribed relationship which exists between the temperature difference of the temperature change and the number of operatable cycles of the power semiconductor element is utilized. SOLUTION: A temperature detection block 11 receives temperature information from a power semiconductor element 10, it detects the temperature of the power semiconductor element 10 on the basis of the temperature information, and it finds a highest temperature, a lowest temperature and a temperature difference in one temperature change cycle on the basis of a change in the current of the power semiconductor element 10. Then, with reference to the found temperature difference, the number of operatable cycles N is read out on the basis of a characteristic which expresses the relationship between the temperature difference and the number of operating cycles. In addition, a counting block 13 counts the number of generations of the highest temperature so as to find the number of integrating cycles (n).  Then, the number of operatable cycles N is compared with the number of integrating cycles (n). When their difference exceeds a tolerance, it is judged that the power semiconductor element 10 is brought close to a failure, and a display such as a warning or the like is performed.

Filed: 1994-09-08
Abstract: PURPOSE: To obtain a uniform illuminance by eliminating the adjustment of a transmissive lamp with respect to a slit in a scanning direction and adjusting the illuminance in a direction orthogonal to the scanning direction. CONSTITUTION: Light emitted from a transmissive lamp 352 is made to be a distribution light whose illuminance characteristic is flat by a reflector and a diffusing plate incorporated in a transmissive light source unit 350, and the flat distribution light is guided to the exposure part of the image recorder through the slit. Thus, the flat distribution light passes through the slit, so that the adjustment of the lamp 352 with respect to the slit in the scanning direction need not be performed even when the lamp 352 is not aligned with a slit center C. Meanwhile, the height of both ends of the lamp 352 is adjusted by rotating a male screw screwed in a screw hole at the base part of a moving plate 380 in the direction orthogonal to the scanning direction. Thus, the uniform illuminance is obtained in the direction orthogonal to the scanning direction.
