摘要： A BiCMOS process which provides both low voltage (digital) and high voltage (analog) CMOS devices. The high voltage NMOS devices have a compensated drain formed by the NPN and PNP base implants. The PNP base plus the high voltage NMOS drain carrier concentrations are both optimized by adjustment of the two variables N base implant dose and P base implant dose; this determines the NPN base carrier concentration which turns out to provide good NPN characteristics. Low voltage NMOS source and drain implants employ a higher dose and may also be used for the high voltage NMOS source. The NPN emitter doping may also be used for a contact to the high voltage NMOS drain contact.

(.rho..sub.20) and T.sub.b (.degree.C.) is a temperature at which the resistivity is 10 times the resistivity at 20.degree. C. (.rho..sub.20). The PTC element is produced by a process comprising mixing a crystalline polyolefin and a conductive filler, molding the mixture into a conductive sheet, press bonding under heat a metallic foil to both sides of the conductive sheet, and repeatedly subjecting the conductive sheet to a heating and cooling cycle consisting of heating at a temperature of not lower than (the melting point of the crystalline polyolefin minus 5.degree.

C. and a high resistivity at a peak temperature, showing a very steep increase in resistance in a narrow temperature range.

摘要： An image data generating circuit of a color image processing apparatus generates multivalued image data for each color in accordance with density of each color of magenta (M), cyan (C) and yellow (Y). An M-screen threshold value generating circuit outputs a plurality of first threshold values, a C-screen threshold value generating circuit outputs a plurality of second threshold values, and a Y-screen threshold value generating circuit for outputting a plurality of third threshold values. A comparing circuit compares the multivalued image data outputted from the image data generating circuit with the first to third threshold values outputted from the M-, C- and Y- screen generating circuits for each color to output a comparison result in the form of a binary signal. The first and second threshold values is assigned to each pixel of an M multi-cell and a C multi-cell constituted by square matrixes having screen angles of .+-.tan.sup.-1 (q/p) and each side of .beta..multidot.p.multidot.q, respectively. For preventing coarse moire, p and q are any value of (11,3), (15,4) and (19,5), and the M multi-cell and the C multi-cell consist of N (=p.sup.2 +q.sup.2) sub-cells arrayed continuously in the directions of the screen angles of .+-.tan.sup.-1 (q/p) and having threshold values in accordance with the predetermined number of gradations. The third threshold value is assigned to a Y multi-cell constituted by a square matrix having a screen angle of 45 degrees and each side of .beta..multidot.p.multidot.q. The Y multi-cell consists of 2(p-q).sup.2 sub-cells arrayed continuously in the direction of the screen angle of 45 degrees. The first to fourth threshold values are repeatedly outputted in a cycle of .beta..multidot.p.multidot.q in synchronism with the multivalued image data of each color.

The two surfaces of the printed circuit board are connected to each other via a through hole to construct the distance measuring circuit. The protecting resin transmits light having specified wavelengths. The light reflected from a subject to be photographed is received by the optical sensor after passing through the protecting resin, and the distance to the subject is calculated on the basis of the received light data.

摘要： Two or more core wires are inserted into an approximately U-shaped barrel of a terminal and fixed to the terminal and each other. The terminal comprises a tab having serrations, formed on the upper and lower surfaces thereof, disposed along the boundary between the core wires so that the serrations shear an oxide film formed on the core wires in contact with the upper and lower surfaces of the tab and remove the oxide film from the core wires, whereby the core wires are electrically connected with each other via the tab. The tab is integral with or separate from a connector terminal or an inter-connecting terminal.
