Abstract: The present invention relates to a method of forming a ceramic or ceramic-like coating on a substrate, especially electronic devices, as well as the substrate coated thereby. The method comprises coating said substrate with a solution comprising a solvent, hydrogen silsesquioxane resin and a modifying ceramic oxide precursor selected from the group consisting of tantalum oxide precursors, niobium oxide precursors, vanadium oxide precursors, phosphorous oxide precursors and boron oxide precursors. The solvent is then evaporated to thereby deposit a preceramic coating on the substrate. The preceramic coating is then ceramified by heating to a temperature of between about 40°C. and about 1000°C. This coating, moreover, may be covered by additional passivation and barrier coatings.

Abstract: A process for the formation of material layers such as amorphous silicon is disclosed. When a precursor gas such as silane is utilized to form amorphous silicon, silicon crystals are often formed on top of the amorphous silicon layer. The crystals are created by the presence of low pressure silane in the reactor at the end of the deposition cycle. Formation of crystals is inhibited by lowering the temperature before silane flow is terminated.

Abstract: The optical circulator comprises : three birefringent crystal plates (22, 23 and 24) ; reciprocal nd non-reciprocal rotators (25) of a first group inserted between plates (22) and (23); reciprocal and non-reciprocal rotators (26) of a second group inserted between plates (23) and (24); and more than two beam incoming and outgoing ports (27, 28, and 29). The rotating directions of the rotators (25) of the first group are so set that the directions in which the oridinary beam and extraordinary beam are separated on the birefringent crystal plates differ among birefringent crystal plate (23) and birefringent crystal plates (22) and (24), and the electric field vibration directions of the beams agree at birefringent crystal plate (23). The rotating directions of the rotators (26) of the second group are set so that the polarization face of the beams are perpendicular to each other at birefringent crystal plate (24). Non-reciprocal operations can be realized in such a manner that beam radiated from a beam incoming and outgoing port "i" among a number N of beam incoming and outgoing ports (1≤ i ≤ N) is emitted from the beam incoming and outgoint port (i+1); and beam radiated from a beam incoming and outgoing port (i+1) is not emitted from the beam incoming and outgoing port "i" but from a beam incoming and outgoing port (i+2). Hence, there is no need to use angular prisms or polarization beam splitters.

Abstract: The invention relates to a method and a device for entraining solid particles of a liquid-jet cutting device in a fluidic cutting jet. Solid particles are to be prepared directly for entraining in the cutting jet and, if the jet flow is interrupted, the introduction of the solid particles is to be automatically interrupted and a directionally independent use of the charged cutting jet is to be made possible. According to the invention, provision is made for solid particles to be moved in a hollow space (6) of a housing (2, 3) of a cutting head and, after a cutting jet is switched on, for the solid particles to be introduced into a mixing chamber (33) by the cutting jet and for the solid particles to be entrained in the jet. In the process, a lower pressure compared with the ambient pressure of the cutting head is set in the carrier medium containing the solid particles in the hollow space. <IMAGE>

Abstract: A data recording disc 1 contains a CD area in which a signal such as an audio signal is recorded in digital form and a video area in which a FM-modulated video signal is recorded with a digital audio signal superimposed thereon. The disc is played back at different speeds for the CD and video areas. A system controller 47 supplies drive pulses to a driver 36 which biasses the pickup 3 detection point radially across the disc and a driver 40 which translates the pickup 3 radially across the disc. The position of a data detection point of a pickup 3 is monitored and a detector 46 detects whether the pickup 3 is over the CD area or video area. The controller 47 changes the width or amplitude of the drive pulses according to the signal provided by the detector 46. This enables the system to make shorter time jumps when over the video area to compensate for the accentuation of disc eccentricity at the higher video disc playback speed.

Abstract: The disclosure relates to an optical filter to be used for signal selection, removal of noise light, wavelength equalization of signal light, etc. in an optical communication, optical measurement or the like, and an optical amplifier employing such optical filter. Signal light is dispersed in different angles according to each wavelength by a diffraction grating and the dispersed light is selectively transmitted or reflected by a transmission type spatial filter or reflection type spatial filter, and is then coupled with an output fiber bundle as non-dispersed light by the diffraction grating. Thus, an optical filter capable of varying wavelength pass band characteristics and an optical amplifier uniform in wavelength amplification factor can be provided.

Abstract: Raster display memories are often arranged to output groups of pixels in progressive blocks, each having a plurality of pixels and each pixel having a plurality of fields. The fields in each pixel may provide color, overlay and cursor information for an individual position on a video screen. The numbers of bits in each pixel and in each field may be variable in different applications. In this system, control information indicates the starting position of each block, the location of each pixel in each block and each field in each pixel and the width of each pixel and each field in number of bits. Using this control information, the system recovers the pixels in each block and the fields in each pixel and processes such information to provide a display of the pixel information on a video screen. The number of bits contained in each field may be expanded to a width (e.g. 8) when the field width is less than eight (8) bits. In this expansion, the expanded field value has an error, compared to the field value before expansion, less than half of the least significant bit in the expanded field. Frequently, the bits in each field before expansion are provided in the positions of greatest binary significance in the expanded field. The unused positions in the expanded field are then filled in the order of progressively decreasing significance by the bits of progressively decreasing significance in the field before expansion, starting from the bit of greatest significance.
