IPC: H01L23/02
Filed: 1981-07-10
Abstract: PURPOSE:To prevent the generation of a crack in an insulating base body by forming the cover member of an insulating frame body disposed while surrounding a semiconductor element by a material having a thermal expansion coefficient equal to a radiator arranged to the base body on which the semiconductor element is placed. CONSTITUTION:The semiconductor element 32 is fixed onto a metallized lyaer 33a shaped to the surface of the vessel base body 31 consisting of a ceramic material, the ceramic frame body 35 is disposed while surrounding the semiconductor element 32 on the vessel base body 31, the cover 36 is fastened onto the frame body, the radiator 38 is mounted to the lower surface of the vessel base body 31, and the radiator 38 and the cover 36 are made of the same member such as copper. Accordingly, since the cover 36 also expands and contracts in the same direction even when the radiator expands and contracts when heat treatment such as fixing is executed, stress applied to the vesel base only 31 is offset, and there occurs no crack in the vessel base body 31.

Abstract: In the outer periphery contact surface (8) of a butterfly disk (3) of a butterfly valve, the sealing area close to a shaft (2), provided for rotating the butterfly disk (3) into its open or closed position, respectively, is formed smaller than other sealing areas of the butterfly disk (3). Thus, when the valve is closed by the butterfly disk (3), the outer periphery contact surface (8) of the butterfly disk (3) starts almost simultaneously contacting a seat ring (5) throughout the periphery because the area of the contact surface (8) is smaller than other sealing areas. Therefore, a reliable sealing effect can be expected for a long time because the butterfly disk (3) is hardly scratched and the seat ring (5) is hardly abraded. <IMAGE>

Abstract: In a busbar protection method and a corresponding device, the maximum values of the currents in the outgoers are determined. The maximum values Ikmax of the current characteristics are extended by a certain hold time th. Subsequently, these current characteristics are processed further vectorially. With the aid of these current characteristics +E,uns Ik+EE  changed in such a way, a fault signal is calculated by means of a protection algorithm, preferably the current comparison method with current stabilization or the phase comparison algorithm. It can be uniquely determined on the basis of the extension of the maximum according to the invention whether an external fault or an internal one is concerned. The advantage of the method and of the device according to the invention resides, in particular, in that the localization of the fault is possible in a reliable fashion even in the case of strong saturation of the current transformers. Above all, false tripping can be reliably avoided even in the case of external faults.

Abstract: A balloon element for use in a catheter has a multi-layered single-walled structure and a compliance characteristic exhibiting a first, non-compliant region at low operating pressures and a secondary compliant region at higher operating pressures. The properties of the balloon element permit it to serve for both dilatation of bodily vessels and stent delivery and implantation. A method of manufacturing the balloon element involves extrusion of a tube of material, such as PEEK, which serves as an inner wall layer of the finished balloon element and provides the desired strength and compliance characteristics of the balloon element, and a post-extrusion over the first tube, which provides an outer wall layer in the finished balloon element imparting abrasion resistance and other desirable mechanical properties.
