Abstract: A method of manufacturing a hose coupling from an intermediate blank material, the hose coupling having an inner tube or tubular nipple portion, an outer tube or tubular sleeve portion and a head portion, all formed by plastic deformation from an intermediate blank material. The head portion is provided with a bore at an end opposite the end where the nipple portion and the sleeve portion are joined. In addition, the head portion is internally provided with a female thread and a conical seal portion.

Abstract: In an AV (audio and video) system, it is possible to suppress such a feeling of a user that he has to wait for an actual operation of an AV appliance after an operation instruction has been inputted until the AV appliance is actually operated. Upon receipt of a recording operation instruction of a VTR 3 issued from a remote controller 2, a CPU 12 first turns ON a power supply of the VTR 3. Thereafter, such a message indicating that the inputted instruction corresponds to the recording operation of the VTR 3 is displayed on a CRT 17. When a user inputs an instruction for confirming this message via a remote controller 2, the CPU 12 instructs the VTR 3 to start its recording operation.

Abstract: Apparatus for receiving super high frequency signals having an outdoor unit which includes a converter for converting super high frequency signals received by an antenna to ultra high frequency signals, a local oscillator for generating a local signal supplied to the converter a switch for switching the frequency of the local signal, and a detecting circuit for detecting an operating voltage supplied to the outdoor unit and the value of which is changed according to a band range of the super high frequency signals, the output of the detecting circuit controlling the switch, an indoor unit which includes a demodulator demodulating the ultra high frequency signals, and a circuit generating the operating voltage; and a coaxial cable supplying the ultra high frequency signals from the outdoor unit to the indoor unit and also supplying the operating voltage from the indoor unit to the outdoor unit.

Abstract: An antenna apparatus has a first wire-like antenna element formed into a rectangular planar loop and a second antenna element which comprises two L-shaped plates electrically connected to the loop and mounted to a rectangular planar base member. The loop is hinged to the planar base member along long sides of the respective rectangles so that the angle between the planes of the loop and base member is adjustable. The base member pivots about an axis on a mount which can be secured to a television receiver.

Abstract: A loop antenna apparatus is disclosed which includes a main conductive loop arranged on a first surface, a plurality of supplemental conductive loops connected to the main conductive loop and arranged on different surfaces from the first surface, respectively, a plurality of signal feeding points provided in different loops of the main and supplemental conductive loops, an output terminal and change-over switches for selectively connecting one of the plurality of signal feeding points to the output terminal.

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.
