摘要： An antenna device for a radio transmission-reception apparatus is disclosed which comprises an antenna element which is to be electrically and mechanically connected to a printed-circuit board fixed in a housing of the radio transmission-reception apparatus, an inverted U-shaped hollow reinforcement spacer, an antenna cover and a retaining portion formed on the housing. The reinforcement spacer has a hole formed in the top portion thereof a diameter of which is substantially equal to that of the antenna element to slide therethrough, a slit formed continuously from the hole to a base end thereof through which said antenna element can be entered in the reinforcement spacer, and a flange formed around the outer circumference of the base end. The antenna cover is constituted to accommodate therein the antenna element with the reinforcement spacer, and has a flange formed around the circumference of a base end thereof. The flanges of the antenna cover and the reinforcement spacer are fixedly supported in the retaining portion provided on the housing in a state that said flanges are stacked upon each other. Since the most of forces caused by vibration and/or impact supplied to the antenna element are absorbed by the reinforcement spacer, a mechanically and electrically connected portion between the antenna element and the printed-circuit board will be effected by the forces and thus damage to the portion will be eliminated.

摘要： A highspeed scanning type radio receiver is disclosed which prevents an erroneous interruption of a scanning operation caused by high frequency noises produced from a clock oscillator and a local oscillator circuit employed therein. The highspeed scanning type radio receiver includes a highspeed clock oscillator, a lowspeed clock oscillator, and a clock switching circuit for switching these highspeed clock oscillator and lowspeed clock oscillator to be connected to a CPU. Normally, a searching operation is carried out by supplying the highspeed clock to the microcomputer. When a reception signal is detected in a certain channel, the highspeed clock is changed into the lowspeed clock to be supplied to the microcomputer, whereby a reception signal is again detected. When no reception signal is detectable, the microcomputer recognizes that the detection of the reception signal under operation at the highspeed clock is caused by high frequency noises, and commences a searching operation of the next channel.

摘要： To avoid deterioration of isolation between two distributed power outputs in higher and lower end portions of an available frequency region of a Wilkinson power distributor, plural stages of ferrite-loaded close-coupled parallel dual lines for providing a Wilkinson power distributor, an electric length of which lines is shortened within a range in which desired isolation can be obtained, are connected in cascade. As a result, two distributed power outputs having a constant phase difference with sufficient isolation throughout an extremely wide frequency range can be obtained.

摘要： For sufficiently shielding an undesired electro-magnetic wave from penetrating into a communication apparatus, for instance, a car telephone through stray coupling, or leaks therefrom, an electronic circuit substrate and a case of the communication apparatus are formed of flat plates which consist of insulating material comprising magnetic material. One side surface of the flat plates are covered with conductive films. The communication apparatus itself is accommodated in the case and an electric power source connecting cable is wrapped by a similar arrangement, so as to remarkably reduce obstructions caused by undesired waves and other communications in comparison with the conventional arrangement.

摘要： For receiving radar waves entering an antenna horn by the heterodyne method, the system is designed so that one of the local oscillation signals produced respectively by a local oscillator for the X- and K-band radar waves, a local oscillator for the Ka-band radar wave, and a local oscillator for leaked local oscillation waves can be selected to be used as the first local oscillation signal for beating down the radar waves at a first mixer. When a radar wave has been detected in the Ka-band receiving mode with the local oscillator for the Ka-band being selected, a signal processing circuit sets the heterodyne receiving system to the leaked local oscillation wave receiving mode, selecting the local oscillator for the leaked local oscillation waves as the first local oscillator. If a radar wave is detected in this mode, the signal processing circuit inhibits a warning apparatus from issuing the regular warning.
