Abstract: The present invention provides a production method of a metal foil comprising the steps of: depositing component particles from a deposition source material consisting of predetermined metal components in a vapor phase onto a substrate disposed to face the deposition source material and having an inert surface moving continuously, by a physical vapor phase deposition method in vacuum or in an inert gas atmosphere so as to form sequentially a thin film having a predetermined film thickness; and peeling off the thin film from the substrate surface to obtain a metal foil. The metal foils thus obtained may be in the state of an amorphous phase, a crystalline phase or a composite thereof by adjusting the gas pressure inside the apparatus, the distance between the substrate surface and the deposition source material, etc. Particularly, metal foils having at least 50 vol.% of an amorphous phase or a surface roughness (Rmax) not greater than 0.2 µm are very useful for various industrial applications because of their superior properties.

A ferrous metal strip (40) is provided, shiftable between an interference position between the permanent magnet and the HED and a clear position not between the permanent magnet and the HED. The indicator is connected so as to be lit when the HED is producing a current within the predetermined range, and not lit when the HED is not producing a current within the predetermined range. Also disclosed is a method for testing the operativeness of a HED. The method includes supplying a testing apparatus as described atove. The apparatus is connected to inputs of the HED, and the indicator observed. The metal strip is then positioned between the permanent magnet and the HED, and the indicator observed, to determine whether the HED is producing a current of at least the predetermined level. In a disclosed embodiment, the HED constitutes part of a vehicle engine distributor, and the ferrous metal strip may be a distributor rotor vane.

Abstract: An interlaced scanning, in which every adjoining plural scanning electrodes (L) are rewritten at the rate of one scanning electrode and all of the picture elements (A) are rewritten in plural fields, is conducted at a constant period. Furthermore, during the transcribing operation of the picture elements (A), a selective voltage (VCA) is applied to the scanning electrode (S) where data to be displayed on the picture elements of liquid crystal display device (20) has changed, and a signal voltage (VSC, VSD, VSG) is applied to the signal electrode responsive to, whether the picture elements on the selected scanning electrode should be changed from a bright display state to a dark display state, or from the dark display state to the bright display state, or the bright and dark display states are not changed. By bringing the field frequency of the transcribing operation above 30 Hz, even when the sixteen adjoining scanning electrodes are rewritten at the rate of one scanning electrode, the display with little flickers can be accomplished.

Abstract: In a method of evaluating pathological conditions, which involves a change in the composition of body fluids, an isolated nerve is initially conditioned in standard electrolyte solution and then a measuring chamber is alternately supplied with a calibration fluid and a test fluid. One then allows a stimulus impulse to act on the nerve by means of electrodes in contact with the nerve and measures the action potential of the nerve actuated by the stimulus impulse for the concerned fluid. 
     The evaluation of the pathological conditions is performed according to the differences in the action potentials between calibration fluid and test fluid or between various test fluids.

Abstract: An infrared emitter 2 whose surface temperature is kept constant during measurement is used to irradiate a measurement region 4 on a roughened material surface with heat with an oblique angle of incidence of the rays. The temperature of the reflected thermal radiation is measured by means of an infrared thermometer 3 which is arranged above the measurement region in such a way that the reflected radiation impinges in the field of view of the infrared thermometer. The overall measurement region of the material surface, which is situated in the field of view of the infrared thermometer, must be irradiated with heat. The measured temperature characteristic of the reflected radiation as a function of the known surface roughness of the material is stored in a comparator 7. This comparator 7 is fed a desired value for the desired surface roughness. The infrared temperature of a material surface which is at first unknown with regard to its surface roughness is measured and compared with the stored temperature characteristic in order to determine the magnitude of the surface roughness. The value thus obtained is used in conjunction with the desired value fed in to form a difference signal which is fed via the output 8 of the comparator 7 to a control unit 9 of a processing device for the material.

Abstract: In known fuel injection valves, the front face of a nozzle body for adjusting the static amount of fuel delivered during the stationary opening state of the fuel injection valve is ground off until the actual amount measured corresponds to the predetermined reference amount of fuel. This method of adjustment has the disadvantage, however, that the front face of the nozzle body can be ground off only when the valve is partially dismantled. In the method according to the invention, the static amount of fuel is adjusted directly on the otherwise finally assembled fuel injection valve, so that the dispersion of the static amount of fuel of the individual fuel injection valves is minimised. For this purpose, a throttle device (87), which serves for metering of the fuel and whose free flow cross-section (89) is variable, is provided upstream of the valve seat. The method according to the invention is suitable for fuel injection valves of various types. <IMAGE>
