Title: Composite member having excellent heat-resistance and oxidation resistance
Inventor: SAKAI MIKIO
IPC: C04B35/56
Filed: 1990-08-03
Abstract: PURPOSE:To produce a composite member having excellent heat-resistance and oxidation resistance by integrating ZrO2 to one surface of a formed carbon fiber article and ZrC to the other surface thereof and continuously changing the concentration from one surface to the other face. CONSTITUTION:A formed article 2 composed of Ir-coated carbon fiber is heated at about 900 deg.C. A raw material gas 13 for forming ZrO2 is passed through the formed article from one surface to deposit ZrO2 3 in the gap 2a between the fibers. Subsequently, a gas 14 for forming ZrC is passed through the formed article 2 from the other surface to deposit ZrC 4 in the gap 2a between the fibers. The composite material 1 produced by the above method contains ZrO2 3 and ZrC 4 having concentrations (concentration distribution) continuously varying in the direction of thickness. The composite material 1 keeps excellent heat-resistance and oxidation resistance even by exposing to high-temperature atmosphere.

Title: Noise eliminating circuit
Inventor: ANDOU MASANOBU
IPC: G01R29/027
Filed: 1981-12-23
Abstract: PURPOSE:To extract only a digital signal with prescribed pulse width even under a noise environmental condition by inputting a digital input signal to an AND circuit and a counter circuit together with clock pulses, and allowing the counter circuit to output the digital signal with the prescribed pulse width only when counting up to a prescribed pulse number. CONSTITUTION:When pulses 5 and 5 having pulse width Wo are inputted as a signal SA from an input terminal 1 to the AND circuit 3 while a noise signal 6 having less pulse width is mixed, they are ANDed with pulses SB from a clock pulse CK generating circuit 2 to output a signal SC. The number of CKS in the signals SC corresponding to pulse parts 5 and 5 in the signal SA is eight and that of the noise signal part 6 is two. When the reference CK number P0 of the counter circuit 4 is set to five, a signal SD of pulses 7 and 7 is outputted at the 5th pulse of the signal SC with regard to the pulses 5 and 5. The pulse width W is as wide as 4 CKs because the output of the signal SD is reset in trailing edges of the pulses 7 and 7 of the signal SA. The CK number 2 of the noise signal 6 is less than P0, so no output is generated corresponding to the to the signal 6. Therefore, the noise signal is discriminated and eliminated.
