Title: Digital horizontal synchronizing circuit
Inventor: NAGAHISA HIDEO
IPC: H04N5/06
Filed: 1989-09-04
Abstract: PURPOSE:To eliminate jitter from a trailing part by using a 2nd polarity discrimination circuit to compare the polarity of a signal resulting from clamping, amplification and integration of an output of a 1st polarity discrimination circuit and of an output resulting from ANDing the output of the 1st polarity discrimination circuit and a signal subject to constant width pulse conversion and integration of the output of the 1st polarity discrimination circuit and discriminating the result of the comparison. CONSTITUTION:An output signal of a buffer circuit 40 is integrated by an integration circuit in a 1st polarity discrimination circuit 50A and reaches a low level of nearly constant potential. An output signal of a reception circuit 10 and the potential are fed to an input terminal of an exclusive OR circuit 51 in the circuit 50A, the level is discriminated and an output signal is obtained, A one-shot multivibrator circuit 60 is acted on the leading and outputs an inverting pulse with a constant width. When the pulse is inputted, a DFF circuit 3 outputs an output signal which descends in response to the leading of the above pulse and keeps a low level till the output signal rises in response to the trailing of the output signal of the circuit 50A. The output signal of the DFF circuit 3 is integrated by an integration circuit 20. An AND circuit 4 generates an output signal. The output signal and one input signal to the exclusive OR circuit 51 are inputted to an input terminal of an exclusive OR circuit 71 and a 2nd polarity discrimination circuit 70 generates an output signal whose trailing has no jitter.

Filed: 1982-12-27
Abstract: PURPOSE:To read data out of an optional address of a main memory of a system of the remote side by obtaining only an answer by a central processing unit at the remote side of a direct memory access data transfer system. CONSTITUTION:When a register access of a data transfer device of the remote side arrives at a connection control circuit 11 via a bus control circuit 10, the circuit 11 drives an answer time monitoring circuit 12 to monitor the answer sent from the data transfer device of the remote side for a prescribed period of time.

Title: Diamond probe and its forming method
Inventor: NISHIKAWA AKIRA
IPC: G01N23/00
Filed: 1988-09-13
Abstract: PURPOSE:To improve the resolution of the device used for the title method by precipitating a carbon film in which columnar diamond crystals and amorphous carbon components are mixed with each other at the front end section of a diamond probe material with a pointed tip and etching the amorphous carbon components only. CONSTITUTION:A carbon film in which columnar diamond crystals 2 and amorphous carbon components 3 are mixed is precipitated on the surface of the diamond probe material 1 obtained by working the front end of a rod wire to a conical form by a vapor phase synthesis method. Then oxygen plasma etching is performed on the carbon film in a microwave plasma CVD device by introducing oxygen gas into the device instead of a mixed gas of hydrogen and hydrocarbon. Since the etching speed of the carbon components 3 by oxygen plasma is overwhelmingly faster than that of the diamond crystals 2, the former is preferentially etched and, as a result, a diamond probe having an extremely sharp pointed tip with protruding diamond crystals 2 is obtained. When a conductive platinum film 4 having a thickness of about several tens Angstrom  is formed on the surface of the probe thus obtained, the probe of a detecting section for scanning tunnel type microscope can be manufactured.
