摘要： A corrugated clamp includes a base section, a lid section, and a bracket section. The base section and lid section are provided on their inner peripheral surfaces with concavo-convex portions to be fitted to an annular concavo-convex portion of a corrugated tube. The bracket section projects from an exterior of the base section to be engaged with a vehicle body. A ground wire is drawn out from a wire harness extending through the corrugated tube. A core wire is exposed from the ground wire by stripping an insulation sheath of the ground wire. The exposed core wire is brought into contact with an inner surface of the concavo-convex portion of the base section and is fixed between the inner surface of the base section and an outer surface of the corrugated tube. An latch piece projected from and integrated with a vehicle body panel is inserted into and engaged with the bracket section to contact the bracket section and the vehicle body panel with each other, thereby electrically connecting the ground wire to the vehicle body panel.

摘要： A transmitting signal from a signal generator is divided in seven transmitting signals in a divider, and the phase and the amplitude of each of divided transmitting signals are changed in a phase shifter circuit and an attenuator circuit. The respective transmitting signals from the attenuator circuit are radiated from scatterer antennas. A receiver receives a multiple wave of radiated radio waves by using a receiving antenna. A computer substantially simultaneously starts operations of a D/A converter, the signal generator, and the receiver by using a trigger generator circuit.

摘要： A grommet is provided with a small diameter tube portion which receives a wire harness therein in a fitted condition, and is provided with an enlarged diameter tube portion which continues in a generally conical tube shape from one end of the small diameter tube portion. A recessed portion for hooking on an automobile body panel is provided on an outer peripheral surface of the enlarged diameter tube portion. The height of first and second peripheral side walls on opposite sides of the bottom surface of the recessed portion is established so that the height of the second side wall of the small diameter tube portion side in the opposite side is about 50% to 35% of the height of the first side wall of the opening end side of the enlarged diameter tube portion side. Furthermore, the width dimension of the recessed portion between the first side wall and second side wall is greater than the height dimension of the second side wall, and the second side wall deforms inwardly into the recessed portion. Thus, the grommet can be easily installed in a single push-in motion of the grommet into the penetration hole of the automobile body panel.

摘要： An antenna apparatus includes a slit provided on an antenna element between first and second feed ports; and a series resonant circuit provided at a location along the slit, with a distance from an opening of the slit. When the antenna apparatus operates at a first isolation frequency identical to a resonance frequency of the series resonant circuit, the series resonant circuit is short-circuited, and only a section of the slit from its opening to the series resonant circuit resonates, thus providing isolation between the feed ports at the first isolation frequency. When the antenna apparatus operates at a second isolation frequency lower than the first isolation frequency, the series resonant circuit is open, and the entire slit resonates, thus providing isolation between the feed ports at the second isolation frequency.

摘要： An antenna element has first and second feed ports, and is simultaneously excited through the feed ports so as to simultaneously operate as first and second antenna portions respectively, associated with the feed ports. The antenna element is excited at one of a first frequency and a second frequency higher than the first frequency. An antenna apparatus is provided with: a slit that provides isolation between the feed ports; a trap circuit that allows the slit to provide isolation at the first or second frequency when the antenna element is excited at the first or second frequency; and a reactance element that shifts a frequency at which the slit provides isolation between the feed ports, to the first frequency, when the antenna element is excited at the first frequency.
