Filed: 1991-06-26
Abstract: PURPOSE: To provide a high-efficiency low-temp. plasma enhanced chemical vapor deposition(PECVD) apparatus for treating the surface of a substrate. CONSTITUTION: The surface treating apparatus comprises a tubular reaction chamber 1 including an electrode 4 for supporting a substrate 10 and tubular coaxial counter-electrode 3 to the electrode 4 surrounded by the counter- electrode 3.

Filed: 1996-07-11
Abstract: PROBLEM TO BE SOLVED: To provide a circuit access method by which such the disadvantage of the FDMA(frequency division multiple access) system that only the terminals of previously prepared channels can make simultaneously communication can be solved. SOLUTION: When a terminal 1 is not able to find a vacant channel after trying access to a channel, the terminal 1 accesses the channel with a restriction in accordance with an instruction from the center station. The terminal 1 prepares such a schedule that a transmitting section D1 and standby section D2 can alternately come by actuating a timer and is enabled to access the channel only in the section D1 in accordance with the CSMA (carrier sense multiple access) system. When the terminal 1 senses a carrier while the terminal 1 tries access to a channel during the transmitting section D1, the terminal resets the timer and restarts the scheduling from the standby section D2 after the carrier disappears.

IPC: G06F9/44
Filed: 1983-09-30
Abstract: PURPOSE:To estimate the convergence period of the development of a program easily from the transitio of update conditions by observing the mean movement value of the number of the mean number of updated records in every section during the update of the program. CONSTITUTION:A library 1 consists of a directory part 2 and members composed of record groups of respective modules 3-1-3-n. The modules have variable length records 4-1-4-m, and each record normally corresponds to one step of the program and is stored with update kind information. When a request to output convergence conditions is made, a main control part 5 actuates a history processing part 7 and a record input part 8 collects records in the library 1. An average arithmetic part 9 calculates the mean number of updated records and a mean movement arithmetic part 10 calculates for example, the mean value for several days. Consequently, variation in the number of updated records due to an external factor such as a day off of a person in charge is reduced to obtain the substantial transition of the number of records.
