Abstract: Data about display start positions are stored in an H register. An H start counter counts an original oscillation signal ORGCLK after the termination of a flyback period, and a comparator detects a start position. Flip flops and NOR gates form a clock having a cycle one and a half times as long as that of the original oscillation signal from the start position, and either the signal having a 1.5-fold cycle or the original oscillation signal is selected according to the level of a mode signal MODE. Thus, it is possible to obtain a clock OSDCLK having a frequency the same as that of the original oscillation signal up to the start position and a clock OSDCLK having a frequency corresponding to magnification from a display position. Therefore, by controlling display of characters based on the clock OSDCLK, display start positions can be made even regardless of magnification.
Abstract: A prior-art electronic circuit component comprising an insulating film and a circuit conductive layer made of a superconducting metal suffers low reliability resulting from insufficient adhesion between these layers. An electronic circuit component of the invention comprises an insulating film made of a high polymer material having a dielectric constant of 2.5 or less, a base metal layer formed of copper on the insulating film, having a thickness of 0.01 to 0.3 .mu.m, and a circuit conductive layer formed of at least one of niobium and niobium nitride on the base metal layer. The electronic circuit component of the invention can accomplish an increased adhesion between the insulating film and the circuit conductive layer.
Abstract: An input buffer circuit is connected to a first power supply voltage pad for applying a first power supply voltage, and a first ground line. An internal circuit larger in power consumption than the input buffer circuit is connected to a second power supply voltage pad for applying a second power supply voltage, and a second ground line. The parasitic resistance of the first ground line is higher than that of the second ground line. By connecting a capacitance between a power supply line connected to the first power supply voltage pad, and the first ground line, fluctuations in first power supply voltage are suppressed to prevent the input buffer circuit from malfunctioning.

The side fins are symmetrically disposed relative to the longitudinal centerline and are so oriented that the center planes of the side fins pass through the foci of the hyperbolic side edges of the tail section.
Abstract: In order to automatically measure the thickness of coatings on a sample, a plurality of calibration curves are stored in a memory circuit beforehand, and X-ray fluorescence generated by irradiation of the sample with primary X-rays is detected by an X-ray fluorescence coating thickness gauge. The X-ray fluorescence is differentiated according to wavelength (energy) by a differentiating circuit. By this differential manipulation, the materials of a sample are identified. Based on the identified constituents of a sample, automatic selection can be made of the most probable and suitable calibration curve out of the plural number of calibration curves stored in a memory and finally coating thickness can be measured on the basis of the selected calibration curve and the intensity of X-ray fluorescence of the sample obtained by the coating thickness gauge.
Abstract: A structure for mounting a high-frequency device on an insulating board having a circuit on a top surface and transmitting signals to the high-frequency device. The high-frequency device is sealed within a cavity on a top surface of a dielectric board. The dielectric board has a first signal transmission line on its top surface and a second signal transmission line on its bottom surface, the first and second signal transmission lines overlapping each other over a portion where the signal is transmitted through coupling of the first and second signal transmission lines. A recess is formed at the top surface of the insulating board below the overlapping portion of the first and second signal transmission lines to suppress transmission loss of the high-frequency signal between the first and second signal transmission lines. The recess may be filled with air or a material having a dielectric constant low than that of the insulating board.

Abstract: In a nonvolatile semiconductor memory device, those sides of the gate insulating film and the floating gate electrode which oppose an inner side of a trench are oxidized to form an oxide film. The gate insulating film, the floating gate electrode, and that portion of semiconductor substrate which is near the gate insulating film oppose an insulator made of a first material buried in the trench via another insulator made of a second material difference from the first material buried in the trench. The first material has a low diffusability of impurities, and is, for example, silicon nitride, which effectively suppresses diffusion of impurities from the second material into the gate insulating film.
Abstract: An image scanning device including a flat bed, a cover for the scanning table, a scanning portion, a carriage for supporting the scanning portion, an automatic document feeder (ADF), a detector for detecting a communication control signal from a remote communication device, and a controller. Upon detecting of the communication control signal (e.g. DIS signal), the controller causes the carriage to move from a stand-by position to either a scanning start position of the ADF, or a scanning start position for scanning a document placed on the flat bed, depending on whether a document is present or not present at the ADF. The time required between the user's pressing the start key and the start of the scanning is reduced.

Abstract: An alkanethiol monolayer membrane is formed on a substrate having an Au layer using Au--S bonding, and a second layer constructed by a monolayer lipid membrane is formed on its surface to form a BLM. A gel layer is formed using agarose on the side of the BLM having the second monolayer lipid layer. In addition, a polymer layer is formed using the amino acid poly-L-lysine between the surface of the monolayer lipid membrane and the gel layer to immobilize the BLM. The use of this supporting constitution for holding and immobilizing the membrane extends the life-span of the BLM, while the gel layer keeps the electrolyte solution required for maintaining flexibility of the membrane and activating protein on the surface of the BLM. In addition, a BLM having a life-span of one month or more is obtained by arranging a membrane supporting portion that minimizes lifting of the membrane molecules due to buoyancy above the BLM arranged upright in an aqueous system.
Abstract: There is disclosed a method of manufacturing a silicon monocrystal in accordance with the Czochralski method in which a seed crystal is brought into contact with silicon melt and is then slowly pulled while being rotated in order to grow a silicon monocrystalline ingot below the seed crystal. In the method, there is used a seed crystal whose a tip end to be brought into contact with the silicon melt has a sharp-pointed shape or a truncation thereof. The tip end of the seed crystal is gently brought into contact with the silicon melt, and the seed crystal is then lowered at a low speed in order to melt the tip end portion of the seed crystal until the thickness of the tip portion increases to a desired value. Subsequently, the seed crystal is pulled slowly in order to grow a silicon monocrystalline ingot having a desired diameter without performance of a necking operation. During the growth of the silicon monocrystalline ingot, a part of the crystal is mechanically held.
