摘要： PROBLEM TO BE SOLVED: To monitor the development of a crack in a wide range of a direction, by measuring the impedances of two extended electrodes constituted so as to pass a current to a resistance layer and the impedance of the resistance layer, and measuring the size of the crack in a processed article or a test piece from the measured values. SOLUTION: Curved electrodes or bus bars 2 are formed on the resistance layer 1 formed on a dielectric substrate 3. A detector is mounted on a processed article or a Lest piece. In the development of the crack of the processed article or the test piece, a crack is generated in the dielectric substrate 3 and the resistance layer 1 in the same pattern as the crack pattern of the processed article or the test piece. When the crack is generated in the resistance layer, the resistance layer 1 is reduced in its cross area to be increased in its resistance. Voltage is dropped between two bus bars 2 by the impedance of the resistance layer 1 and this voltage drop corresponds to the impedance of the resistance layer 1. The voltage drop has the linearity corresponding to a crack size by the curving ratio of the bus bars 2, and is made substantially regardless of a crack developing direction.

摘要： A method of forming a fine point or spike or array of fine points or spikes on a substrate (5) in which an electron beam (6) is focussed onto the substrate (5) at each point that a fine point or spike is required. The substrate (5) is positioned within a low pressure atmosphere, the atmosphere containing a precursor of the material for example a hydrocarbon or organo-metallic gas which forms the fine point or spike. The focussed electron beam (6) causes the deposition of material onto the substrate (5) to form the fine point or spike. An array of such fine points or spikes can be used as a field-emitter cathode surface in vacuum electronics.
摘要翻译：在基板（5）上形成精细点或尖峰或尖晶石或精细阵列的方法，其中电子束（6）在需要微小点或尖峰的每个点聚焦到基板（5）上。基材（5）位于低压气氛中，该气氛含有形成细微点或尖峰的材料的前体例如烃或有机金属气体。聚焦的电子束（6）导致材料沉积到衬底（5）上以形成细微点或尖峰。这样的精细点或尖峰的阵列可以用作真空电子器件中的场致发射极阴极表面。

摘要： A porous electrode for a fuel cell is made by dusting nickel powder of a particle size of 65 to 75 microns into a dish-shaped plate and sintering without pressure at a temperature between 1325 DEG C. and 1350 DEG C. for an hour in hydrogen or a mixture of hydrogen and nitrogen. A second layer having finer pores is then produced on the first layer by painting on it a suspension in alcohol of nickel powder having a particle size of 4 to 5 microns and sintering at 1000 DEG C. for half an hour. In an alternative method of making the first layer, nickel particles of size 7 to 9 microns or 4 to 5 microns are mixed with ammonium bicarbonate of 100-240 mesh in the proportion of 1 part by weight of the bicarbonate to 3 to 5 parts of nickel. The mixture is pressed at 4,000 lbs. per square inch and then sintered at 1000 DEG C. to 1150 DEG C. for half an hour to 3 hours. The Provisional Specification describes modifications of the sintering processes in one of which the temperature at which the coarser nickel particles of 65 to 75 microns are sintered is reduced to 1150 DEG C. by sintering in an atmosphere of hydrogen and nitrogen which has been passed through hydrochloric acid.
