Title: Noise eliminating circuit for video signal
Inventor: OZAKI HIDETOSHI
IPC: H04N5/21
Filed: 1986-12-09
Abstract: PURPOSE:To improve the noise cancelling effect by extracting respectively a moire component and high frequency components constituting a noise separately so as to apply noise cancel based on the small amplitude part of the high frequency components and the moire component. CONSTITUTION:A filter 12 filters a moire component having a frequency nearly twice the low frequency chrominance carrier frequency from a difference signal corresponding to the level difference of the luminance signals at preceding present one horizontal scanning periods and a detecting means 15 detects it when the reproduced chrominance signal is larger than the reference level. On the other hand, a high frequency component generating means 4 subtracts the output signal of the filter from the high frequency components of the difference signal during the detection period and gives an output to a limiter 5 and outputs the high frequency components of the difference signal to the limiter 5 as it is in other period. A noise component generating means 20 generates a signal being the sum of the output signal of the filter and the output signal of the limiter 5 as a noise component during the detecting period and outputs the output signal of the limiter 5 as a noise component in other periods.

Title: Disconnection detection device of power conversion apparatus
Inventor: SUZUI KOSUKE
IPC: H02H7/122
Filed: 1990-10-29
Abstract: PURPOSE:To enable disconnection to be detected with a simple circuit configuration by detecting generation of disconnection based on a state of resonance phenomenon which is generated at a switching element and a coil. CONSTITUTION:For example if it is set so that a negative input value (reference value) of a converter 40 is not available at an output when it is normal and is available in the case of a disconnection, an output of an AND 42 outputs H value when either connection out of connections 28 related to each drive circuit 24 is disconnected. A controller 22 takes in this output as a disconnection signal and detects disconnection of the connection 28. Therefore, even if a plurality of pairs of transistors are used for phases 12U. 12V, and 12W of a power conversion apparatus 12, generation of disconnection can be detected by resonance which is generated at one coil 36 per each of the phases 12U, 12V, and l2W, thus enabling the disconnection to be detected without increasing circuit configuration.
