Filed: 1992-02-19
Abstract: PURPOSE:To efficiently and stably perform etching treatment at high reproducibility by automatically controlling an RF voltage to an arbitrary value in each etching step by processing the RF voltage as an electric signal during etching. CONSTITUTION:By forming plasma in a reduced-pressure container 2, a sample 11 placed in the container 2 is etched by using the plasma. In such plasma etching system, the etching is performed by automatically controlling an RF voltage to an arbitrary value in each etching step by processing the RF voltage as an electric signal during etching.

Title: Train group control simulation system
Inventor: ASUKA AKIRA
IPC: B61L27/00
Filed: 1992-02-19
Abstract: PURPOSE:To provide a simulation system which shows group control value settings and delay settings and simulation results with easy operation and supports the understanding of group control effect. CONSTITUTION:A simulation for trains is split for every station section to realize simulation setting, easily handled by operators. In other words, the delay of trains is set by changing initial data before entered into a routine, and when trains under simulation are not simulated at the first time in the station-to-station section, reference data out of signal status data for previous trains is taken out of the position and time of trains and then other simulation data are also used to perform usual simulation for train position and speed renewal. As a result of train position renewal, when a blocked section where trains exist is changed, signal change data for trains under simulation are written in accordance with a signal change rule. Such work is done until trains arrive at a station.

Abstract: PURPOSE:To obtain the optical transmission system in which a wavelength multiple number is extended and the system is economized. CONSTITUTION:A transmission terminal station forms a frame of a reference optical series whose wavelengths are lambda1, lambda2,..., lambdan with a time window tauref (a time when a reference light is sent) and a time window tauo (a time when no reference light is sent) and send the reference light through an independent reference light transmission fiber (frame time T (tauref+tauo)) or through the same fiber (frame time T (tauref+tauo+taus)) as for the signal light (time window taus for the signal light), and sends the wavelength multiple optical signal synchronously with the reference light series. Then the receiver side takes frame synchronization by detecting the time window tauo for which no reference light is sent, extracts a desired reference light based thereon, a narrow band optical filter takes tuning between the extracted reference light and signal light to obtain the signal light with a desired wavelength. Through the constitution above, the transmission system does not required a light source whose absolute wavelength is made stable, and the reception system does not need a narrow band optical filter of highly stable operation whose passing wavelength is warranted, and the wavelength multiple number is simply increased.
