A dot pattern 41a is formed by rotating the basic pattern, the result is quantized to generate a small cell and threshold level data are assigned to unit squares being components of the small cell. For example, threshold level data = 12 denoting a minimum value are added to the set of the basic threshold level data and the set of the threshold level data obtained as a result of the addition is assigned to the dot pattern 41a. In the case that the small cell has 8 unit squares, the threshold level data = 12 denoting a minimum value are deleted from the set of the basic threshold level data and the set of the threshold level data obtained as the result of deletion is assigned to the small cell with the 8 unit squares.

Title: Acid concentration measuring apparatus
Inventor: YAMAMOTO MASAAKI
IPC: G01N1/10
Filed: 1986-11-28
Abstract: PURPOSE:To measure the concentration of acid quickly, by a method wherein a sample liquid containing a volatile acid and a low volatile salt flows to an anticorrosive tube and the anticorrosive tube is heated to evaporate the volatile acid, which is made to flow out, to leave the low volatile salt in the anticorrosive tube. CONSTITUTION:A sample liquid 4 containing a volatile acid and a low volatile salt is passed through a tube 5 to be introduced into an anticorrosive tube 6 together with a carrier gas. The anticorrosive tube 6 is arranged within a water jacket and heated up to a fixed temperature. Here, the temperature is so adjusted that the salt then left as intact is prevented from thermally decomposed while the evaporated residue will not be fouled. The volatile acid flows cut accompanied by the carrier gas and cooled with a condenser 10 to liquefy. The acid condensation liquid is fed with pure water 11 and sent to a acid concentration measuring section 12 to measure the concentration of acid. After the measurement, a cleaning water is introduced at a water injection port 15 to wash the salt left in the anticorrosive tube 6. This allows the acid alone to flow out of the sample liquid, thereby enabling quick measurement of acid while facilitating the washing of the salt left.
