Abstract: A planar small antenna and a small strip radiator are provided which have increased bandwidth. The small strip radiator has a main strip pattern and a plurality of convoluted strip patterns terminating the main strip pattern at each end. The plurality of convoluted strip patterns are arranged in mirror-symmetrical arrangement with reference to the longitudinal axis of the main strip such that one pair of convoluted strip patterns is convoluted clockwise while another pair is convoluted counterclockwise. As a result, an electrically small antenna radiator requires less metal or conductive material than conventional radiators, and also can operate without adversely affecting the radiation characteristics of the antenna.

Abstract: A multifunctional control device and method is used to determine a head channel selecting signal for playback heads of a video tape recorder and for controlling a phase shift direction of a video signal according to a desired reproduction mode. The video tape recorder has four heads, a first pair for use during standard play and a second pair for use during super long play. The heads read out recorded video signals and a first switch is connected to the first pair of heads and a second switch is connected to the second pair of heads for selectively providing outputs to corresponding amplifiers, under control of a servo controller. A third switch is connected to the outputs of the amplifiers for providing outputs under control of a microcomputer. The microcomputer controls the servo controller which in turn controls the speed of a drum motor and a capstan motor. The microcomputer also provides a phase shift direction controlling signal. An output of the servo controller is provided to the microcomputer along with an output of a comparator comparing the outputs of the amplifiers.

Abstract: A method of forming a pattern includes forming a mask pattern on a substrate; etching the substrate by deep reactive ion etching (DRIE) and by using the mask pattern as an etch mask; partially removing the mask pattern to expose a portion of an upper surface of the substrate; and etching the exposed portion of the upper surface of the substrate. In the method, when a pattern is formed by DRIE, an upper portion of the pattern does not protrude or scarcely protrudes, and scallops of a sidewall of the pattern are smooth, and thus a conformal material layer may be easily formed on a surface of the pattern.
