Title: Formation of calibration curve in gas analyzer
Inventor: NAGANO TAKASHI
IPC: G01N35/00
Filed: 1992-07-18
Abstract: PURPOSE:To easily and exactly obtain a calibration curve and prove justifiability of the obtained calibration curve by approximating the calibration curve on the of an output value corresponding to gas concentration to a polynomial expression and finding an error of its primary differential. CONSTITUTION:Gas for calibration different in concentration is supplied to a gas analyzer 3 through a gas separator 2 and at the time 4 on move values of output corresponding to gas concentration are taken. A calibration curve is approximated to a fourth order or less polynomial expression f (x) (x indicates analyzer output for showing concentration) by means of the least square method based on the value of 4 or more. A primary differential f' (x) of an approximate expression f (x) is checked within 1.05 times as large as the concentration of zero to a full scale. And, when f' (x) >=0 is indicated, a full scale error and a leading point error are found and the approximate expression f (x) is accepted as a calibration curve if these is within a range of an allowable error determined in a specific standard. Beyond the allowable range these are returned to the start, the approximate expression is found in the next order (for instance, a tertiary expression is used when a first fourth- order expression is approximated).

Filed: 1984-10-12
Abstract: PURPOSE:To improve printing quality by optimumly driving a replaced ink ribbon, by automatically changing a driving system in a horizontal direction when a different kind of ink ribbons are replaced. CONSTITUTION:A character code and a control code are sent from an upper rank apparatus. In usual, these codes are decoded and edited by a printer control pat 2 through an interface control part 1 to perform printing. Because the indication of an ink ribbon to be used is not generally given from the upper rank apparatus, the difference of the ribbon is known on the basis of the signal from a mechanism 4 by a ribbon check part 5 at the ON-time of a power source. This information is sent to the printer control part 2 and, after said information is confirmed by the printer control pat 2, a different drive demmand in a horizontal direction is issued to a drive part 3 by the printer control part 2. The drive pat 3 decodes the drive dammand and performs the replacement of an internal table value to alter a drive system. Therefore, good printing is obtained.

Title: Forming method of al alloy thin film wiring
Inventor: HATTORI KEI
IPC: H01L23/52
Filed: 1994-09-08
Abstract: PURPOSE: To restrain generation of etching residue after an Al alloy thin film is etched, by heat-treating a metal thin film and the Al alloy thin film at a specified temperature after the metal thin film is formed on the Al alloy thin film containing Si. CONSTITUTION: On a silicon oxide film 12, a Ti thin film is formed, on which a titanium thin film 14 is formed. After a second Ti thin film 16 is formed on an Al alloy film 15, the films 15 and 16 are subjected to second heat treatment for reflow at 600 deg.C or lower for 3 minutes. As the result, Si does not condense in the Al alloy film 15 in the course of the second heat treatment, but Si in the Al alloy film 15 reacts with a part or the whole part of the second Ti thin film 16, so that titanium silicide is formed. Thereby generation of etching residue can be restrained when the Al alloy film 15 is etched by using photoresist 18 as a mask.
