Abstract: In a digital video compression and decompression method and system, matrices of pixels in RGB, YUV or CMYK formats are accepted for data compression. The data are rearranged in 8x8 pixel blocks, each block being of one pixel component type. The pixel data are then subjected to a discrete cosine transform (DCT). A quantization step eliminates DCT coefficients having amplitude below a set of preset thresholds. The video signal is further compressed by coding the elements of the quantized matrices in a zig-zag manner. This representation is further compressed by Huffman codes. Decompression of the signal is substantially the reverse of compression steps. The inverse discrete cosine transform (IDCT) may be implemented by the DCT circuit. The circuits may be implemented in a single integrated circuit chip. Three levels of compression rate control are provided during processing of video data.

Abstract: This is a method for preparing a substrate for semiconductor devices. 
     The substrate is prepared either by directly bonding a bonding wafer to a base wafer or by bonding the bonding wafer to the base wafer with an oxide film formed on at least the bonding surface of the bonding wafer or the bonding surface of the base wafer to make the finished semiconductor devices provided with an SOI structure. 
     Prior to the bonding operation as stated above, the bonding wafer and the base wafer are subjected to the following processes:
     (1) making the diameter of the bonding wafer smaller than the diameter of the base wafer,   (2) setting the beveling width of the back side (bonding side) of the bonding wafer at 50 micron or less, and   (3) beveling the front side of said base wafer so that the bonding surface of the base wafer is made equal in size to the bonding surface of the bonding wafer.   
     Thus, when the bonding wafer, which has been bonded to the base wafer, is subjected to polishing into a thin film, the peripheral portions of the bonding wafer form a smooth surface of the base wafer. This prevents the peripheral portions from chipping off.

Abstract: A flame retention plate (46) for a power burner (10) is designed to alter the direction of flow of air passing through openings (52, 54, 56) in the flame retention plate (46). The direction of air flow is altered by a ramped surface (58) forming a portion of each opening (54) in a ring of intermediate openings disposed between inner small openings (52) and outer large openings (56). The ramped surface (58) is oriented for directing air radially outwardly to mix with air flowing through the outer large openings (56). This action creates a partial vacuum at discharge orifices (49, 50) formed in a gas supply tube (20), with the orifices (49, 50) being disposed downstream of the flame retention plate (46), to actively suck gas out of the gas tube (20) to enhance mixing of gas with air. Highly efficient combustion of the mixed gas and air results, providing a flame close to the flame retention plate (46).

Abstract: Modulated data information having an individual one of different baud rates and aural information are converted at a transmitter from analog to digital form. A controller separately identifies the digitized aural and modulated data information and, if modulated data, identifies the baud rate of such modulated data. The aural information is separately transformed. For modulated data, the information is separately processed in accordance with the different baud rates. The individual ones of aural and modulated data are then introduced to a common line for packetizing. The beginning of each packet is labelled to identify whether the packet contains aural information (such as voice or music) or modulated data (such as modem or facsimile) and, if modulated data, the particular baud rate of such information. An individual code identifies the end of each packet. The packetized information is then multiplexed in a common bus with other packetized aural and data information. At a receiver connected to the common bus, the multiplexed information is separated into the different packets. The packetized information representing individual ones of aural information (such as voice or music) and modulated data (such as music or facsimile information) is separated, in accordance with the packet labels, into aural information and modulated data and, if modulated data, is introduced to an individual one of different modulators each operative at an individual one of the different baud rates. The aural information is then transformed substantially to its original form at the transmitter and the modulated data is separately processed in accordance with the different baud rates.

Abstract: In an optical wavelength converting apparatus, a laser beam serving as a fundamental wave (11) and having been obtained by pumping a solid laser medium (16) is caused to impinge upon a nonlinear optical crystal (10), and the type II of phase matching between the fundamental wave (11) and its second harmonic (12) is effected. The second harmonic (12) of the fundamental wave (11) is thereby radiated out of the optical wavelength converting apparatus. A solid laser medium (16), which produces a linearly polarized fundamental wave (11) in two longitudinal modes, is employed as the solid laser medium. A device (30,31,32,33) for adjusting a difference in phase of the fundamental wave (11) due to the nonlinear optical crystal (10) and a device (53) for adjusting the temperatures of the nonlinear optical crystal (10) and a resonator, such that the temperatures may be kept at predetermined values, are provided in order to work such that two directions of polarization of the fundamental wave (11) may intersect approximately perpendicularly to each other and may respectively incline approximately 45° with respect to an optic axis of the nonlinear optical crystal (10). The second harmonic (12) having stable output power and free of any noise is thus obtained.

Abstract: A main controller (20) installed in a distribution substation (10) of an electric power system sends a request signal to each of section controllers (30-1, 30-2, 30-3) installed in individual section switches (12-1, 12-2, 12-3, 12-4) upon detecting a distribution line fault. Each of the section controllers (30-1, 30-2, 30-3) performs fault detection individually. Each section controller (30-1, 30-2, 30-3, 30-4) judges whether its associated section switch is dividing the distribution line (11) between faulty and normal line sections on the basis of fault detect signals from the other section controllers (30-1, 30-2, 30-3, 30-4). If it is judged that its associated section switch is dividing the distribution line (11) between faulty and normal line sections, that section controller opens its associated section switch (12-1, 12-2, 12-3).
