Filed: 1988-11-30
Abstract: PURPOSE:To correctly measure distortion level of intermodulation of dielectric itself to be measured by providing non-contact structure at an input part with input signals radiated from two input loops. CONSTITUTION:Trap resonators 32 are placed between dielectric resonators 26 and input loops 22, and resonance electromagnetic field of the dielectric resonators 26 is enclosed between the trap resonators 32 so that one of the input loops 22 is free from influence of intermodulation signals from the other input loop 22. With a distance between the dielectric resonators 26 and the trap resonators 32 adjusted, both are critical-coupled. This realizes a useful method and a useful apparatus for measuring intermodulation distortion of dielectric materials in an RF band and enables correct estimation of dielectric resonators to be used as filters for commonly used transmission apparatuses of mobile communication stations.

Title: Magnetic recording and reproducing device
Inventor: ASAI SHIGEKI
IPC: G11B15/28
Filed: 1992-10-16
Abstract: PURPOSE:To prevent an oil from flowing into a tape contact part and to evade the generation of a problem such that the traveling of a tape traveling system is made unstable, by providing knurled parts at the positions holding the tape contact part of a capstan shaft in between. CONSTITUTION:When a flywheel 7 is rotated, the capstan shaft 4 integrated therewith is also rotated, thence the oil is gradually made to flow out on the surface of the capstan shaft 4 from an oil retaining bearing 3.

Title: Time base correcting device for video signal using dpsk signal
Inventor: OKADA KAZUO
IPC: G11B20/02
Filed: 1987-12-02
Abstract: PURPOSE:To compensate a time base variance component especially in the high band of a video signal by correcting the time base variance of the video signal based on a DPSK (differential shape-shift keying) superposed on the video signal by an electronic still camera standard. CONSTITUTION:A DPSK signal 28 included in a video signal 16 outputted from a disk reading part 10 is separated from the other video signal components by a band pass filter 20 and is inputted to a DPSK demodulator 30 and is outputted as a reference signal 34 and is supplied to a write control circuit 58. Since the DPSK signal 28 included the time base variance component of the video signal 16 and the write control circuit 58 generates a control signal 60 based on the DPSK signal 28, the control signal 60 includes the time base variance component. Consequently, video signal data is written in a storage position, which is corrected in accordance with the time base variance in memories 46 and 48. Thus, the time base variance of, especially, the high band component of the video signal 16 according with the electronic still camera standard is properly corrected.

IPC: G06F11/22
Filed: 1986-12-19
Abstract: PURPOSE:To improve the guarantee level of a check circuit by diagnosing a check circuit during the on-line operation of a system by utilizing the free time of a program. CONSTITUTION:When the program has a free time during on-line execution, an OS monitor 30a actuates a service processor SVP 20 and sets a CPU 10 so that an external interruption can not be initiated. Then latch data on test points of check circuits 11a-13a of the CPU 10 are saved.
