Title: Color printing apparatus
Inventor: SASAKI ISAO
IPC: B41J2/30
Filed: 1989-06-30
Abstract: PURPOSE:To produce gradation in color printing by changing the striking force of a head pin to paper by changing the exciting time of the coil driving the head pin. CONSTITUTION:When a common signal is set to LOW, Q2 is turned ON through an inverter T1 and a driver T2 and Q4 is turned ON. When a gate signal is set to LOW, Q3 is turned ON through an inverter T3 and an AND circuit T4 when a data signal is Hi and turned OFF when the data signal is LOW. When the data signal is Hi, a current flows to a coil L and, when the data signal is LOW, no current flows to the coil L. When the common signal is set to Hi in such a state that the data signal is Hi, Q1, Q2 and Q4 are turned OFF and a current passes through the route of L   Q3 ground   diode D1  L to reduce by the quantity consumed in the coil L. When the gate signal is set to Hi, Q3 is turned OFF and a current flows through the route of L  diode D2 +34V. By changing the LOW time of the common signal, the current IL flowing to the coil L also changes and the striking force of a head pin to paper also changes to produce color gradation.

Abstract: PURPOSE:To effectively remove SO2 and SO3 by using magnesium oxide as an absorbent. CONSTITUTION:Magnesium oxide powder is sprayed from a magnesium oxide powder storage hopper 1 into a flue 5 in which SOx contg. gas flows. The magnesium oxide powder is guided to an absorber 9 while absorbing SO2 in flue gas in the flue 5. In the absorber 9, the magnesium oxide comes into contact with a circulating liquid from a spray line 7 and is collected by it. The circulating liquid absorbs SO2 in the flue gas to remove it while it falls in the absorber 9. The circulating liquid is circulated from the bottom part of the absorber 9 by a circulating pump 10. The sulfite ion concentration of the circulating liquid is detected by a detector 18. When the detected sulfite ion concentration is lowered, oxidation by an oxidizing blower 13 is restrained to improve the activity of the magnesium oxide by the presence of the sulfite ions in the liquid. The feed rate of the magnesium oxide is controlled by a control unit 14 based on signals given by a detector 16 for SOx concentration in gas, a gas flow rate detector 17 and a pH meter 15.
