Abstract:
In a high-frequency coaxial cable (1), an internal solid layer (3), an insulation layer (4) made of a foam resin, an external solid layer (5), and an external conductor (6) are provided on the periphery of an internal conductor (2) in this order. The external solid layer (5) has a dielectric dissipation factor of 1.0×10−4 or less at 2 GHz. Thereby, the voltage standing-wave ratio and the attenuation of the high-frequency coaxial cable (1) are reduced.
Abstract:
An imaging apparatus in which positions of an X-ray image and optical image of a subject can be brought into registration with each other is provided. A half-mirror is provided between the X-ray source and subject and is configured to pass X-rays and reflect visible light. A TV camera captures the optical image of the surface of the subject reflected by the half-mirror. A display unit displays the optical image captured by the TV camera together with a reference mark indicating the reference position of this optical image, and displays, in superimposed form, an X-ray image obtained by capturing a prescribed reference object as a subject by using an X-ray imaging unit. An adjusting unit adjusts position and attitude of an X-ray detector in such a manner that the reference object displayed by the display unit will coincide with the reference mark.
Abstract:
The magnification of an image is set. The distance between the positions of two designated points on the image is measured. On the basis of the set magnification set and a measurement value, an actual measurement value on the object corresponding to the measurement value of the distance between the positions of the two designated points on the image is calculated. The set magnification, the measurement value, and the calculated actual measurement value are simultaneously displayed.
Abstract:
Diversity receiver 100 provided with receiving LSI device 10, antennas 11 and 12, RF circuits 25 and 26 and main CPU 27 is disclosed. Receiving LSI device 10 receives diversity signals through antennas 11 and 12 and RF circuits 25 and 26. One of ADCs 30 and 31 and a part of CDM 32 provided in demodulator 14 are only energized to save electric power consumption when a receiving quality of the diversity signals is acceptable, or both ADCs 30 and 31 and CDM 32 are otherwise fully energized. Bit-interleave circuit 15, Viterbi decoder 17 and receiving-quality-judgment circuit 19 connected in parallel with Viterbi decoder 17 are provided to detect an error rate for the receiving quality judgment. Further, byte-interleave circuit 20, Reed-Solomon decoder 22 and receiving-quality-judgment circuit 24 connected in parallel with Reed-Solomon decoder 22 are also provided to detect another error rate for the receiving quality judgment. Main CPU 27 is connected to receiving LSI device 10 to supply demodulator 14 with a control signal based on the error rates detected by receiving quality judgment circuits 19 and 24.

Abstract:
The travelling speed of a magnetic tape is controlled without considering a detection error caused by the slackening of a magnetic tape or the like. A microcomputer 10, immediately after starting a fast-feeding operation, starts a running rotation of feeding and winding reels 44, 45 (step S205), calculates an N value based on reel pulses and sets an acceleration target (step S210, S215) and simultaneously reads the N value immediately before the previous stop of the rotation from RAM and compares the read N value with the current N value (step S225, S230), prohibits the acceleration of the feeding and winding reels 44, 45 after confirming that the error does not fall within 25% (step S235) whereby when the videotape is rotated to the leader or the trailer, the videotape is prevented from being applied with an excessive load so that damages on the videotape can be reduced.
