Title: Substrate-cleaning method and manufacture of semiconductor device
Inventor: KATO TOSHIO
IPC: H01L21/306
Filed: 1997-09-09
Abstract: PROBLEM TO BE SOLVED: To lessen chemical liquid in consumption and to remove contaminants in a groove which is narrow in opening width and large in depth by a method, wherein one of the vapors of sulfuric acid, hydrochloric acid, a nitric acid, a chlorosulfonic acid and the like is used to clean the surface of a substrate. SOLUTION: A processed substrate 30 is cleaned with a cleaning chemical vapor. A chlorosulfonic acid liquid 102 is poured into a flask 101 and kept without being heated at a normal temperature. Nitrogen gas is made to pass as a carrier gas through a chlorosulfonic acid liquid 102 via a piping 103 and guided into a chamber 106 which houses the processed substrate 30. A nitrogen gas which contains chlorosulfonic acid is sprayed at the surface of the processed substrate 30 for a prescribed time. Moreover, when a hydrochloric acid is used, a hydrochloric acid vapor is fed directly from a hydrochloric acid cylinder to spray against the surface of the processed substrate 30.  Through this setup, a chemical liquid is turned into molecular form, so that the chemical liquid is capable of penetrating easily into a narrow and deep groove, enhanced in contaminant removing effect, and markedly lessened in consumption.

Title: Frame synchronizing system
Inventor: NIIHORI KOICHI
IPC: H04N19/70
Filed: 1987-09-30
Abstract: PURPOSE:To shorten a time required for synchronization establishment and to decrease a time change by incorporating a main frame synchronization information bit to establish the synchronization of the main frame and a unit frame information bit to indicate the transmission sequence of the unit frame into the unit frame in the previously set transmission sequence out of the plural unit frames. CONSTITUTION:In respective unit frames 17, main frame synchronization information bits 19a to consist of code rule violation bits are provided at the top bits of the respective units frames 17 of every eight unit frame of first, ninth,... 41st ones. At the respective 6 bits from the second to the seventh ones of the respective unit frames 17, unit frame information bits 19b to indicate a binary- displayed number is set. When a subscriber line terminal 2b on a receiving side to receive the said data detects the information bit 19a, the synchronization of a main frame 18 is established. Further, when the unit frame information bit 19b is detected, the synchronization of the unit frame 17 is established. In such a way, since the synchronization of the unit frame 17 is established simultaneously with that of the main frame 18, the time required for the synchronization establishment can be drastically shortened.

Title: Method for forming recognition dictionary
Inventor: YAMAGATA HIDEAKI
IPC: G10L15/06
Filed: 1990-09-14
Abstract: PURPOSE:To make it possible to form a recognition dictionary (RD) of high performance from the small number of RD records by forming a feature variable to be registered in the RD from a cluster obtained by clustering and repeating processing to be registered in the RD to form the RD. CONSTITUTION:A seed point setting part 40 detects the feature variable of a RD to be a misrecognition source and the feature variable of a RD most frequently generating mesrecognition out of misrecognized RDs and sets up these values as an initial cluster. A clustering processing part 50 executes clustering based upon ISODATA method by using the set initial cluster. An RD forming part 60 forms the average feature variable of each cluster from the obtained cluster and registers the formed feature variable in an RD memory 80 as a dictionary. Then, recognition processing is executed again by using the formed dictionary. When a recognized result exceeds a required recognition rate, the RD forming processing is ended. Consequently, the RD of high performance can be formed from the small number of RD records.
