Patent JP-S5733867-A (JP)
Title: Facsimile equipment
Inventor: ONO MASARU
IPC: H04L29/08
Filed: 1980-08-08
Abstract: PURPOSE:To separately divide a transmisstion control signal communication period and a data  transmission period, by sending back a response signal to a picture data receiving request, etc.  from the other equipment, after a transmission control signal to be transmitted to the other equipment from the own equipment has been sent out completely. CONSTITUTION:For instance, when only a FAX transmission from an equipment 21 to an equipment 22 is being executed, an original transmission request from the equipment 22 to the equpment 21 is executed. A picture transmission part 26b detects an original and informs to a control  part 24b of its fact. The control part 24b sends out an ENQ signal from a transmission control  signal transmission part 25b. When the ENQ signal is received in the equipment 21, a control part  24a makes preparations for sending out a receiving preparation confirming signal CFR in accordance with the status of a picture receiving part 32a and a picture transmission part 26a. When the  picture transmission part 26a finishes to transmit an original end signal RTC and informs to the  control part 24a of the fact, the control part 24a inquires of the picture transmission part 26a  whether an original to be transmitted is left or not, and in case there is still an original, a multipage signal MPS is sent out from a transmission control signal transmission part 25a, and after  that, the CFR signal is transmitted.

Title: Dry etching device
Inventor: ITO FUMIKAZU
IPC: C23F4/00
Filed: 1986-05-14
Abstract: PURPOSE:To enhance the selection ratio of etching and to prevent the damage of a substrate by impressing a high-frequency voltage wherein the higher voltage of the periodically changing voltages is low enough in comparison to the amplitude on an electrode to be loaded with the substrate to be etched. CONSTITUTION:A processing gas is introduced in a plasma treating chamber, and the electric power impressed on the upper electrode 3 by a high-frequency power source 1 through a matching box 2 is conducted to a grounding through a substrate electrode 6 and a capacitor 12 to generate plasma between both electrodes. The ion formed in the plasma is injected on the substrate 5 which is put on the substrate electrode 6 through an insulator sheet 4 to carry out etching. A synthetic voltage obtained by combining the voltage generated by passing a current I1 from a waveform generator 7 through a dummy load 9 with a voltage from a variable DC bias power source 10 is impressed on the substrate electrode 6 in the dry etching device. The higher voltage of the synthetic high-frequency voltage VA is made sufficiently close to zero V in comparison to the amplitude. Consequently, the distribution of the energy injected on the substrate 5 is reduced, and the high-energy ion is eliminated.
