    摘要: A sampling circuit for a sampling oscilloscope comprises a sampling gate circuit receptive of an input signal to be sampled. A sampling pulse generator circuit develops narrow sampling pulses which are applied to enable the sampling gate circuit. Input signal samples from the sampling gate are applied to an amplifier which in turn applies input signal samples to another gate circuit. The other gate circuit receives gate signals developed in synchronism with the sampling pulses by a gate signal generator to enable the other gate circuit. When the other gate circuit is enabled an input signal sample is applied to a memory circuit which stores the input signal sample therein. A feed circuit and an output amplifier receive the output of the memory circuit. The feed circuit develops a first signal proportional to the input signal sample stored in the memory and applies the first signal to the other gate circuit when the other gate circuit is enabled to store a subsequent input signal sample in the memory circuit. The feed circuit develops a second signal proportional to the input signal sample stored in the memory by the same amount as the first signal and subtracts the second signal from the input signal to the output amplifier. The first and second signals developed by the feed circuit reduce amplitude fluctuations in the output of the sampling circuit.

    摘要: An attenuator for a wide range of frequencies has a dielectric plate supported within first and second outer-conductors. A rectangular resistive member is deposited on the surface of the dielectric plate and is contiguously interposed between two pairs of highly conductive electrodes. An impedance compensation member having substantially the same shape as the rectangular resistive member is deposited on either the inner surface of the first outer-conductor or the second outer-conductor so as to at least compensate for variation of the characteristic impedance produced when a high frequency current flows in the electrodes.

    摘要: An electrophotographic apparatus comprises supporting means for rotatably supporting a roll of paper, a mechanical system for advancing the paper through the apparatus, a roller rotatably mounted along the advancing path of the paper for eliminating the tendency of the paper to reroll; a cutting device for cutting the paper into separate sheets, and sensing means for sensing the consumption of the roll of paper. The supporting means comprises a rotatable shaft having a flange mounted on each end thereof for supporting therebetween the roll of paper. One end of the shaft is provided with a helical thread which cooperates with a pivotal lever on one flange to releasably and adjustably mount the flange on the shaft. A biasing spring urges the lever into engagement with the helical thread to releasably lock the flange on the shaft and the spring may be compressed by manually pivoting the lever against the spring force whereby the flange may be slid off of the shaft so that another roll of paper may be mounted thereon.

    摘要: A circuit for controlling an intensity of a scanning in an electromagnetic deflection type cathode ray tube generates an unblanking pulse only when a current change exists in a deflection coil of the cathode ray tube. The unblanking pulse is applied to an intensity modulation grid of the cathode ray tube thereby a fluorescent surface is maintained in an unblanking condition when the current change exists in a deflection coil and in a blanking condition when no current change exists in a deflection coil. As a result of this, an intensisty of a scanning can be in constant brightness independent of the scanning velocity and further, a burning of the fluorescent surface of the cathode ray tube can be prevented in case movement of a brightness spot is stopped.
