Title: Chemical substance detecting method
Inventor: IWAMA AKIFUMI
IPC: G01N27/416
Filed: 1994-06-29
Abstract: PURPOSE:To identify chemical substances in gas phase. CONSTITUTION:Measuring electrodes 20, 22 and a reference electrode 26 are formed in the lower face of a measuring part 10 and a solution supplying pipe is opened in the lower face. Attributed to the surface tension, the electrolytic solution is kept on the electrolytic solution keeping surface 21 at the lower end of the measuring part 10 by suppling the predetermined electrolytic solution from the solution supplying pipe and thus a gas reception part is obtained. Since the electrolytic solution is directly exposed to air, substances in the gas phase (especially odorous substances) are diffused to the part. The electric condition alteration of the measuring electrodes 20, 22 attributed to the diffusion is detected. Since the electric condition alteration with the lapse of time is different depending on each chemical substance, the chemical substance in the gas phase can be identified by distinguishing the pattern.

Title: Printing correction system
Inventor: NISHIKAWA HARUYUKI
IPC: G06K15/10
Filed: 1987-06-15
Abstract: PURPOSE:To allow no dots to be printed at the left and right side of a character pattern and also a single dot to be omitted in the middle as far as circumstances permit by providing a shift register, flip-flops, a left end conditions determiner and a right end conditions determiner. CONSTITUTION:When a character pattern is input to a shifter register SR under a condition such as '001111' from the left, '0' is set to flip flops D0, D1 and '1' is set to flip-flops D2 to D5. At that time, AND gates 10, 14 output '0' each so that a transistor is set to 'OFF' state, performing no printing. After this, the character pattern is shifted by single dot, setting '0' at the flip-flop D0 and '1' at D1-D5 each. Under this condition, the AND gate 10 outputs '1' and a transistor of driver DR is set to 'ON' state, printing '1'. The above process occurs thereafter and left end dots and right end dots become '0', while an inner adjoining dot becomes '1'. Consequently, a printing pattern contains no 'continuous 1'.
