    摘要： A semiconductor sensor of the present invention is capable of preventing a diaphragm portion of the sensor from being damaged if a weight collides against a semiconductor integrated circuit substrate of the sensor and is further capable of preventing the diaphragm portion from being bent significantly even when a semiconductor sensor element of the sensor is disposed inside a distorted or deformed casing. A rear surface of the semiconductor integrated circuit substrate 7 is joined onto a wall surface of the casing 9 that defines a receiving chamber of the casing. A support portion of the semiconductor sensor element is joined onto a front surface 7a of the semiconductor integrated circuit substrate 7. A shock absorbing layer is formed on the front surface 7a of the semiconductor integrated circuit substrate 7 at least on a part thereof facing the weight 3 of the semiconductor sensor element 7, for suppressing the bouncing of the weight 3 when the weight 3 collides against the semiconductor integrated circuit substrate 7.

    摘要： A duplex transmission and reception system wherein a local oscillator of the receiver is dispensed with by using the output of a modulated transmission oscillator, with its modulation cancelled, in lieu of a receiver local oscillator. The transmitter modulation signal is adjusted by appropriate level correction and phase inversion. The modulated output of the transmission oscillator is itself applied to a modulator, where it is modulated by the adjusted modulation signal. This results in substantially cancelling out the modulation component of the transmission oscillator output. This modulation-cancelled signal is supplied to the mixer of a superheterodyne receiver as a local oscillator signal.

    摘要： A semi-coaxial cavity resonator filter including a plurality of semi-axial cavity resonators, as constructed units, each of which has an adjustable device in which dielectric substrates having a specific dielectric constant of more than 1 are disposed in the gap between the inside wall of a tube-shaped outer conductor and the open end of an inner conductor provided on the inside wall of the outer conductor, and the electrostatic capacitance of the spaces interposed by the dielectric substrates is changed without steps by varying the area of the electrodes on the dielectric substrate. The filter is made by making an individual and predetermined frequency adjustment on the plurality of the semi-axial cavity resonators and then cascade-connecting those resonators in one block through shielding plates having a coupling iris so as to obtain desired filtering characteristics as a bandpass filter.

    摘要： A transmitter having a transmitting phase synchronizing system. To one input of a frequency mixer is applied the output of a phase synchronizing type digital frequency synthesizer, through a first frequency divider. A modulating signal is applied to another input of the frequency mixer. The output from the mixer is connected via a bandpass filter to a phase synchronizing system having in series, along a main route, a phase detector, a lowpass filter, and a voltage controlled oscillator, and thence to an amplifier system. In a feedback route from another outlet of the voltage controlled oscillator to the phase detector is a second fixed frequency divider. The digital frequency synthesizer itself may have a reference oscillator connected in series to a third fixed frequency divider, a second phase detector, a second lowpass filter and a second voltage controlled oscillator, from which a feedback circuit leads back to the phase detector via the first fixed frequency divider and a variable frequency divider.
