Inventor: AKAISHI MINORU
IPC: C09K3/14
Filed: 1985-11-07
Abstract: PURPOSE:To prolong the life of an apparatus and to obtain cubic boron nitride in a high yield by adding the nitride of a transition metal to pyrolytic boron nitride and holding them under conditions of high temp. and pressure within ranges in which cubic boron nitride is thermodynamically stable. CONSTITUTION:The nitride of a transition metal is added as a catalyst to pyrloytic boron nitride and they are held under conditions of high temp. and pressure within ranges in which cubic boron nitride is thermodynamically stable to convert the pyrolytic boron nitride into polycrystalline cubic boron nitride. The pyrolytic boron nitride used is highly oriented boron nitride synthesized by a special production method called a chemical vapor deposition method (CVD method). It is necessary to add the catalyst by >=0.1mol% of the amount of the pyrolytic boron nitride as starting material. In case of <0.1mol%, conversion into cubic boron nitride is not completely carried out. Even when the catalyst is added by an extremely large amount, the effect is not enhanced and the maximum effective amount is about 10mol%.

Abstract: PURPOSE:To attain an high speed arithmetic operation by providing a correction circuit that is provided before and behind the 2-input binary adder circuits at a first step and corrects input data for calculation with binary adder circuits. CONSTITUTION:To two inputs of respective adder circuits a1-a4 at the first step, the data by n-bit corresponding to the first and second decimal data are inputted, to their carry inputs the low-order one bit by the (n) bits corresponding to a third decimal data is inputted.

Title: Monitoring method for optical transmission line
Inventor: OMAE KAZUYA
IPC: H04B10/07
Filed: 1993-09-10
Abstract: PURPOSE:To avoid distortion from being caused in an output even when an excessive input os received by an optical receiver by modulating an optical pulse with a carrier having a higher frequency than a maximum frequency of a carrier of a video signal so as to prevent generation of beat noise even when the light of a same wavelength band is applied to a video signal and an optical pulse for monitor thereby decomposing the superimposition of optical pulse and video signal. CONSTITUTION:A monitoring optical pulse 2 from an OTDR system is sent to an optical transmission line 1. The optical pulse 2 is a signal of the same wavelength band as that of the video signal such as 1.3mum band or 1.55mum band and modulated by a carrier 7 whose frequency is twice or over of a maximum frequency of the carrier of the video signal. The width of the optical pulse 2 is decreased more than a transmission time per one picture sent by the video signal. After the reflected light of the optical pulse 2 from the optical transmission line 1 is converted into an electric signal by an O/E converter 5, a band pass filter 6 extracts only the carrier component of the optical pulse 2 and the component is detected by an OTDR 3 and a loss waveform in the lengthwise direction of the optical transmission line 1 is measured.
