Abstract:
An arc discharge metal halide lamp having a discharge chamber having visible light permeable walls bounding a discharge region supported electrodes in a discharge region spaced apart by a distance Le with an average interior diameter equal to D so they have a selected ratio with D exceeding a minimum value. Ionizable materials are provided in this chamber involving a noble gas, one or more halides, and mercury in an amount sufficiently small so as to result in a relatively low maximum voltage drop between the electrodes during lamp operation for a lamp dissipation sufficient to have the chamber wall loading exceed a minimum value or so as to maintain chamber luminosity above a minimum value for a selected operational duration.
Abstract:
A reference apparatus for determining a current or voltage of a semiconductor device, includes a plurality of reference cells having threshold values different from each other, and a selection circuit for selecting one of the plurality of reference cells. A current flowing in a semiconductor device can be determined by comparing the current flowing in the reference apparatus, with the current flowing in a semiconductor cell by means of a sense amplifier.
Abstract:
A ribbon and a bonding wire are connected respectively to a high-frequency input and output of a microwave circuit, the width of the ribbon and/or the thickness of the bonding wire being varied continuously or discontinuously at a portion other than a portion used for bonding. By applying the ribbon and bonding wire to a microwave circuit package including a metallic substrate and sealing therein an MMIC mounted to the metallic substrate, desired high-frequency characteristics of the MMIC can be obtained.
Abstract:
A MOS transistor includes a semiconductor substrate of a first conductivity type having a major surface, a source and drain of a second conductivity type formed on the major surface to define a channel region therebetween, and a gate arranged in the channel region via an insulating film. The MOS transistor includes an impurity-implanted region of the first conductivity type located at a substrate portion which is deeper than the channel region and is shifted to a source side from a region corresponding to the channel region.
Abstract:
A tunnel oxide film is formed on the surface of a p-type silicon substrate, and a floating gate electrode made from a polysilicon film is formed on the surface of the tunnel oxide film. On the surface of the floating gate electrode, a control gate electrode is formed via an NON film formed by sequentially stacking a silicon nitride film, a silicon oxide film, and a silicon nitride film. A side oxide film is formed on the side surfaces of the floating gate electrode and the control gate electrode. Source and drain regions made from an n-type diffused layer are formed on the surfaces of element regions of the silicon substrate on the two sides of the floating gate electrodes.

Abstract:
A radar module includes a high-frequency signal generator comprising upper and lower parallel conductive plates, at least one dielectric rod held between the parallel conductive plates, a metal diode mount held between the parallel conductive plates, a gunn diode member mounted on a side of the diode mount, and a printed-circuit board mounted on the side of the diode mount in covering relationship to the gunn diode member and having a bias supply circuit on its surface for supplying a bias voltage to the gunn diode member. One terminal of the gunn diode member extends through a through hole defined in the printed-circuit board, is exposed in the vicinity of the surface of the diode mount, and is connected to the bias supply circuit. The printed-circuit board has a rectangular metal pattern dimensionally adjustable for adjusting the oscillation frequency of the gunn diode member, and a varactor diode for modulating the frequency of a signal generated by the gunn diode member so that the high-frequency signal generator can function as an FM signal generator.
