IPC: H01L23/12
Filed: 1985-09-26
Abstract: PURPOSE:To improve the hermetic properties and the heat dissipating properties, by sealing an eyelet with glass through an iron oxide produced on a metal coating film. CONSTITUTION:A coating film 22 of a metal which can produce an iron oxide, for example an iron plated film, an iron-nickel-cobalt alloy plated film or an iron-cobalt alloy plated film is formed on the surface of an eyelet 10 which is to be sealed with hard glass 14. After the coating film 22 is heated in the atmosphere of an oxide to produce an iron oxide on the film 22, the eyelet is sealed with the hard glass 14. A lead line 12 and an earth lead line 16 which are also sealed with the hard glass 14 are also coated previously with a metal oxide film by means of the oxidation. The eyelet 10 is formed of copper-tungsten alloy, which has a rate of thermal expansion relatively close to that of the hard glass 14. Further, the adhesion properties between the glass 14 and the iron oxide is extremely high. Accordingly, desirable hermetic properties and desirable heat dissipating properties can be obtained even after the heating treatment.

Abstract: PURPOSE:To effectively perform the self-recovery to a failure by use of a case in which recovering work is described. CONSTITUTION:Cases CS1-CS5 are hierarchically classified according to failure symptoms, failures and classes A-C, and a case suitable to a caused failure is selected to perform recovering work. Application priorities are given to the classes A-C, and when the applicable case is present in plural classes, the application priorities are referred to at need. When the application of the case is successful, the application priority of the class to which the case belongs is raised to make this class easy to apply. When the failure can not be recovered by the case application, the work is inferred by qualitative inference to recover the failure. When it is successful, the inferred work is registered as the case of a new class.

Abstract: A dictionary retrieval apparatus and method for retrieving a TRIE (Tree Retrieval) dictionary based on a lattice as a key, in which each candidate character of a recognition result is handled as a data node, and the character lattice is structured by connecting each of candidate characters with the control nodes. Based on control node connection information, character strings corresponding to each of the paths are retrieved by traversing the data nodes of a character lattice from a head to a tail. According to this method, a higher retrieval efficiency is achieved in comparison with the processing in which matching with the dictionary is implemented after all retrieval keys contained in the character lattice are generated.

Abstract: An electrosurgical system and method allow the surgical team to perform electrosurgical interventions, such as ablation and cutting of body structures, while limiting the depth of necrosis and limiting damage to tissue adjacent the treatment site. The system includes an electrosurgical probe having a shaft with a proximal end, a distal end, and at least one active electrode at or near the distal end. The active electrode includes at least one active portion having a surface geometry configured to promote substantially high electric field intensities and associated current densities between the active portion and the target site when a high frequency voltage is applied to the electrodes. These high electric field intensities and current densities are sufficient to break down the tissue by processes including molecular dissociation or disintegration. The high frequency voltage imparts energy to the target site to ablate a thin layer of tissue without causing substantial tissue necrosis beyond the boundary of the thin layer of tissue ablated. This ablative process can be precisely controlled to effect the volumetric removal of tissue as thin as a few layers of cells with minimal heating of or damage to surrounding or underlying tissue structures.

Abstract: In summary, the invention is related to the discovery of a class of compounds which inhibits the reaction of a polyepoxide with a curing agent at low temperatures. An epoxy resin composition contains a) a polyepoxide; b) an amine or amide curing agent for the polyepoxide; c) at least about 15 meq (per equivalent of polyepoxide) of a catalyst for the reaction of the polyepoxide with the curing agent; and d) a cure inhibitor selected such that: (1) at about 171  DEG C the composition has a gel time that is at least about 50 percent longer than a similar composition without the inhibitor, and (2) at about 175  DEG C and higher the composition cures in no more than about 50 minutes. The composition can cure rapidly with high crosslink density because it has a high catalyst loading, but the inhibitor lengthens the gel time to permit laminating and other processing.
