Abstract:
An antenna system is disclosed which has a loop antenna divided into n conductive members at n pairs of divisional points where n is a positive integer not smaller than 2, n feeders connected to the n pairs of divisional points respectively, a signal feeding point, and at least one impedance element. In this case, electrical switching circuits are connected between the n feeders and the impedance element, and an electrical control circuit is connected to the electrical switching circuits for selectively connecting the feeding point to one of the n feeders and at the same time for selectively connecting the impedance element to another of the n feeders, so that the directivity characteristic of the antenna system is variable controlled.
Abstract:
In recording periodic information signals having first intervals and second intervals which are subdivisions of the first intervals, for example, the chrominance components of color video signals having field and line intervals, and which are recorded in respective areas or increments of successive parallel tracks on a record medium; interference due to crosstalk between signals recorded in next adjacent tracks is substantially reduced or eliminated by recording the information signals in such next adjacent tracks with first and second carriers, respectively, which have their phases changed in opposite directions by 2 pi /N and 2 pi /M, respectively, for successive second intervals, with each of N and M being a whole number greater than 2 which is negative to indicate a phase change or shift in the clockwise direction or positive to indicate a phase change in the counterclockwise direction, and with each of N and M being selected to satisfy the equation 1/N-1/M=1/2.

PROBLEM TO BE SOLVED: To provide a transmission line element and an electronic device which can increase variations in the capacitance to ground during signal transmission using a small size and a simple structure. SOLUTION: At least a part of a region corresponding to a hollow portion G in a conductive pattern layer 17 is displaceable with respect to a substrate surface by means of an electrostatic actuator including a lower electrode 121, an upper electrode 122 and a drive voltage supplier 19. Thus, the capacitance to ground with respect to the substrate surface can be easily varied in the conductive pattern layer 17 that serves as a signal line. COPYRIGHT: (C)2011,JPO&INPIT

Abstract:
PURPOSE:To prevent a touch panel device from turning to malfunction or non- operation state by forming an alternative beam when an element is damaged in the touch panel device, in which an optical beam lattice is formed by a light receiving element and light emitting element. CONSTITUTION:For an optical beam constituting a sense surface, an R beam BR37 is formed by a photo-transistor TR37 and light emitting diode DR37, for example. When the light emitting diode DR37 is damaged by any cause (samely as the photo-transistor TR37), a light emitting diode DR35 and photo-transistor TR39 are selectively driven by an R beam drive selector and a defective beam alternative beam BR37' is formed. Thus, even when the element is damaged and a defective beam is generated, the device can be prevented from turning to the malfunction or non-operation state.

CONSTITUTION:When an IC card 1 is inserted into an IC card fitting part 7 and an interactive button 8 is depressed, an interactive mode is obtained, the picture data from a ROM 2 is read, and a still picture is displayed on a monitoring screen 6a. When a user speaks to the monitoring device, the voice is detected through a microphone 10 with a voice detecting circuit 25 and a controller 15 and a voice synthesizing circuit 27 are operated. The controller 15 reads the voice data from a ROM 3. The voice data is added to the voice synthesizing circuit 27, a voice signal is synthesized and the voice signal is supplied to a speaker 11.
