摘要： A subsample signal processing apparatus includes a wide-band D/A converter receiving a digital television signal which is compressed in band by subsampling. A signal processor subjects a video signal portion of an output signal from the D/A converter to wide-band processing. The signal processor subjects a sync signal portion of the output signal from the D/A converter to narrow-band processing. An output terminal of the signal processor and an input terminal of a subsequent A/D converter are coupled with wide-band coupling characteristics.

摘要： An image signal processing apparatus is provided which is applicable to a motion adaptive Y/C separation of an NTSC signal and a time-domain/spatial interpolation of a high definition television signal band-compressed by sub-Nyquist sub-sampling. The apparatus includes a still image processing circuit having frame memories, a motion image processing circuit having a line memory, a mixing circuit for mixing outputs of these processing circuits, a circuit for detecting image motion of an input image signal and applying a resultant control signal to the mixing circuit, and a signal mode control circuit for selectively adapting the image processing circuits for the processing of the NTSC signal or the high definition television signal. The motion detecting circuit includes a narrow band detecting circuit for producing a one-frame interval difference signal of a signal spectrum of a pure low frequency component from the NTSC signal or the high definition television signal respectively, a wide band detecting circuit for a two-frame interval difference signal and a composition circuit for composing outputs of these detecting circuits. The still image processing circuit, motion image processing circuit and mixing circuit are adapted to operate for the Y/C separation with the NTSC signal and for the interpolation of the high definition television signal, respectively.

摘要： A television receiver is provided with two field memories for storing movement control signals, an OR circuit, a frame memory for storing the present and previous fields, a pair of switches controlled by a freeze signal, a switch controlled by the output signal of the OR circuit, and another switch for changing over its output signal to and from the output signal from the switch controlled by the OR circuit and the signal from the frame memory representing the present field. One frame's worth of video signals of the present field and the previous field are stored in the frame memory by a freeze signal. The signals stored in the frame memory provide a freeze picture having no multi-line dimness by virtue of using the present field and the previous field for the still picture image portion and the present field for the moving picture image portions of the present field and the previous field.

摘要： An optical disc signal processing device includes a focus position determining section, wherein when test recording is performed while changing a focus position through a plurality of positions, the focus position determining section obtains an optimum recording focus position based on recording qualities of regions on the optical disc where the test recording has been performed. The focus position determining section includes: a recording state measuring section for measuring, for each focus position, a recording quality of a region on the optical disc where the test recording has been performed; and a determination section for determining, according to a predetermined criterion, whether laser power during the test recording is suitable for obtaining the optimum recording focus position, based on the recording quality obtained for each focus position by the recording state measuring section. When it is determined by the determination section that the laser power during the test recording is not suitable for obtaining the optimum recording focus position, the optical disc signal processing device controls the optical pickup so that the test recording is performed again with the laser power changed.

摘要： A chemical vapor deposition method that utilizes conventional CVD equipment to deposit silicon dioxide films is provided. The method is capable of producing excellent step coverage on substrates with steep step portions. Tetra-ethoxy-ortho-silicate, acetic-acid, and water are independently gasified by gasifiers and are fed into a reaction chamber. The mixed vapor is heated in the chamber to activate a chemical reaction so that high-fluidity tetra-hydroxy-silicon can be uniformly deposited on a semiconductor substrate containing step portions. Subsequently, two water molecules are detached from tetra-hydroxy-silicon in a dehydration process thereby forming silicon dioxide.

摘要： In sputtering equipment, a pair of targets are positioned in spaced apart relation defining a space therebetween. Each of the targets forms an electrode that is connected to a voltage supply unit. The voltage generates an electric field between the target pair. Furthermore, a process gas is supplied to the space between the targets. As the gas flows through this space, the electric field excites the gas into a plasma state. The plasma, being proximate the targets, causes the material comprising the targets to be sputtered. Additionally, to increase the plasma density in the space between the targets, a magnetic field is applied orthogonally to the electric field. A substrate, upon which the target material is sputtered, is positioned within the sputtering equipment opposite the targets. Further, because the target surfaces from which the material is sputtered are not parallel to the substrate, sputtered particles strike the substrate from an oblique angle. Such oblique striking angles produce a thin film upon the substrate having improved step coverage.

摘要： A plasma generator having two groups of interleaved electrodes to which power is allied at high or radio frequency, to form a plasma in a region sufficiently removed from a substrate to avoid damage and unwanted exposure of the substrate to the plasma. In one embodiment of the invention, the electrodes are flat parallel plates. One group of electrodes includes all the odd-numbered plates and the other group includes all the even-numbered plates. In another embodiment of the invention, the electrodes are concentric cylinders instead of flat plates. In either case, plasma generation makes use of a relatively large electrode surface area in a small volume, and the resulting plasma is not in direct contact with the substrate being processed.
