Abstract: PROBLEM TO BE SOLVED: To make each of outer surfaces of bending parts of a flat tube-shaped film not be coated heavily with coating fluid and not to be left undried even when each of the outer surfaces of the bending parts are coated heavily to a certain degree with the coating fluid. SOLUTION: The coating and drying method forms a coat comprising a coating ingredient on both outer surfaces of a film F by a method wherein the flat tube-shaped film F is passed through the inside of a coating fluid tank 13 and then passed through the inside of a drying apparatus 5. In this case, excess coating fluid adhering to vicinity of both ends of the film F is scraped off by gas blown from a nozzle 14 toward the vicinity of both the ends of both the outer surfaces of the film F before the film enters into the inside of the drying apparatus 5 after the film F exits from the inside of the coating fluid tank 13. Sometimes the vicinity of both the ends of both the outer surfaces of the film F is overdried when the film F is passed through the inside of the drying apparatus 5.  Each of both the outer surface of the film F is pressed by a coating fluid-scraping bar 15 with specified pressure before the film F enters into the inside of the drying apparatus 5 after the film F exits from the inside of the coating fluid tank 13.

Title: Semiconductor power module and compound power module
Inventor: GOORABU MAJIYUMUDAARU
IPC: H02M7/5387
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To prevent a load from concentrating on a part of semiconductor power switching elements. SOLUTION: A diagnostic circuit PC of a module 10a (10b) judges whether abnormality is generated in a collector current, by comparing, e.g. a sensing signal SSE which is sent out from a sensing circuit Se and proportional to the collector current of an IGBT element with a reference voltage. When an abnormality exists, a cutoff signal SSD is sent to a cutoff circuit SD, and the IGBT element is cut off. At the same time, an abnormality detection signal SF01 (SF02 ) is sent to the other module 10b (10a). When the abnormality detection signal SF01 (SF02 ) is received, a diagnostic circuit PC of the module 10b (10a) sends a cutoff signal SSD to the cutoff circuit SD, and cuts off the IGBT element. Both timings of sending the cutoff signal SSD coincide with each other, so that both of the IGBT elements are simultaneously cut off.  Hence it can be prevented that either one of the IGBT elements is cut off in advance and a load concentrates on the other belated IGBT element.
