Title: Method and device for recording and reproducing pcm signal
Inventor: FURUHATA TAKASHI
IPC: G11B20/10
Filed: 1982-01-11
Abstract: PURPOSE:To improve the S/N margin of a reproduced signal to a code error, by giving an FM modulation to a PCM signal and recording it after converting it into a bipolar code. CONSTITUTION:An FM signal (b'), i.e. an output given from a PCM signal is converted into a bipolar signal (c') and then delivered through 2. This signal (c') is recorded directly to a magnetic recording medium 100 with a constant current by a magnetic head 200 and amplified by a reproduction amplifier 4 to receive the equalization of waveform by a reproduction equalizer 5. An output signal (e') given from the equalizer 5 is delivered through output terminals 30 and 40 respectively after an FM signal (f') corresponding to the original signal (b') is restored by a limiter 7, etc. and then the data and the clock of the PCM signal are demodulated respectively. In such a way, a reproducing system requires no emphasizing circuit in particular. This can improve the S/N margin to a code error.

Title: Formation of wiring
Inventor: MIZUTA TAKAYUKI
IPC: H01L21/3205
Filed: 1992-01-09
Abstract: PURPOSE:To prevent wiring from being thinned by side etching and to prevent plated layers from being formed in other than wiring formation parts, when the wiring is formed on an insulating or semi-insulating board by electroless plating. CONSTITUTION:The title forming method for wiring has processes of applying photoresist 8 containing a catalyst for plating, of plasma calcination after transferring a wiring pattern, of removing a catalyst layer 11 remaining in other than the wiring pattern part by spatter etching, and of electroless plating after increasing adhesion by heat treatment.
