    摘要： An antenna circuit which is improved in the deterioration of amplitude characteristic in a strong electric field, an antenna circuit for AM broadcasting which can surely inhibit and damp FM-band signals in the strong electric field and amplifies to output AM-band signals, and an antenna circuit for AM/FM broadcasting in which AM-band signals are not damped by means of an FM-band filter. In the first antenna circuit, the output signal of an antenna (10) is supplied to the base of a transistor Tr2 forming a current amplification type amplifier having a high-input and low-output impedance and the emitter of the transistor Tr2 is grounded through a coil L6 and connected to an FM receiver (16) through a band-pass filter (38). In the second antenna circuit for receiving AM broadcasting, an input terminal is connected to an AM amplifier circuit (36) through coils L7 and L8 in series and to the gate G of a field effect transistor FET. The source S of the transistor FET is grounded and the connecting point of the coils L7 and L8 is grounded through a capacitor C15 and a coil L9 in series. The second antenna circuit inhibits and damps FM-band signals in a plurality of steps. In the third antenna circuit for AM/FM broadcasting, the output signal of an antenna is divided into two parts and one part is supplied to an FM-band filter (12) through a serial FM resonance circuit (30) composed of capacitors and coils. The other part of the output signal is supplied to an AM-band filter (34).

    摘要： A motor-driven antenna device in which an antenna element (10) has a short protruding length so that the outer dimension of the entire device is reduced, and in which damping of an AM-band signal by a signal path is restrained with a small stray capacitance. A rack cord (12) to be meshed with a pinion gear (24) is connected to a proximal portion of the antenna element (10) made of a helical coil over its entire length, and the antenna element (10) is caused to protrude and move to be housed by rotational driving of a motor drive section. The rack cord (12), the motor drive section and the pinion gear (24) are housed in a case (14), and a guide (26) to which the rack cord (12) is abutted and moves while bending is provided in the case (14). Thus, the rack cord (12) is abutted and moves to the guide (26) by the movement of the antenna element (10). In a protruding state, a linear conductor (30) is extended from the proximal end of the antenna element (10) to penetrate an earth conductive fitting (16), and electrically connected with a connection conductive fitting (32) at a position not in contact with the earth conductive fitting (16). A feeder conductive fitting (34) elastically contacts and is electrically connected with the linear conductor (30).

    摘要： A movable pin (11) having a movable projection length at the front end is disposed and a plurality of probes, such as a signal probe (3) and a power supply probe (4), are disposed to extend through a metal block (1) to allow the front end of the movable pin to project at one surface side of the metal block (1). A test subject device (20) is pressed against one surface side of the metal block (1) to contact the electrode terminals (21-24) of the test subject device with the front ends of the individual probes, thereby testing the test subject device for its characteristics. At least some of these probes are formed around the outer periphery thereof with a dielectric layer and a metal film, thereby providing a capacitor load type probe having a capacitor formed therein. As a result, noise elimination can be reliably effected, and using it as a power supply probe makes it possible to suppress voltage drop across the power supply terminals even if the output varies.

    摘要： An antenna for mounting on a vehicle which restrains damping of a signal voltage by reducing a stray capacitance of a signal path and has an improved antenna characteristic and a short physical length, and an antenna element which is suitable for an antenna for mounting on a vehicle and is flexible by using a helical coil of a large winding diameter are provided. In the antenna for mounting on a vehicle, with respect to a band signal having a short wavelength of a plurality of band signals to be transmitted/received, an antenna element (10) is caused to resonate with a physical length shorter than ¼ of the wavelength of the band signal. A linear line portion (12) is provided at the proximal end, and the antenna element (10) is provided at a predetermined distance from a vehicle body (14) and a conductive member of the same electric potential as the vehicle (14). The stray capacitance between the proximal end portion of the antenna element (10) and the vehicle body (14) is small, and a signal voltage is outputted without being damped. The antenna element (10) is formed by burying a helical coil (48) coaxially into a flexible insulating resin pipe (44). The pitch of the helical coil (48) is not shifted even when it is bent repeatedly. Also, no sink mark is generated in the insulating resin pipe (44).

    摘要： The antenna element (1) of a long conductor is formed with at least one returned portion (1a) arranged substantially in parallel to a longitudinal direction of the antenna element. In practice, a physical length of the antenna element in the longitudinal direction is determined to such a length as to be substantially resonated in a first frequency band, and the at least one returned portion (1a) is formed in such a way as to be resonated in a second frequency band twice higher than the first frequency band on the basis of an electric coupling with the adjacent antenna element. Further, the antenna can be constructed in such a way that: an antenna element (1) of a long conductor is formed with at least one returned portion arranged substantially in parallel to a longitudinal direction of the antenna element in such a way that an electrical length thereof is substantially 3/4 wavelength of a frequency band of transmitted and received signals; and at least half element (213) of an electrical length of substantially 1/4 wavelength of the frequency band beginning from an end portion of the antenna element on a side opposite to a feeder portion (30) side is formed as an extended antenna piece extending substantially in non-parallel to the substantially parallel-formed antenna elements (211, 212).
