Title: Phase controlling synchronization circuit
Inventor: OOSAWA YOSHINOBU
IPC: H02M1/08
Filed: 1979-01-31
Abstract: PURPOSE: To perform stabilization and attain a high accuracy through a very simple circuit, by prescribing the constants of a phase transformer and an AC filter.  
     CONSTITUTION: Power voltage 1 is used to energize a polyphase thyristor converter. The power voltage is changed by a phase transformer 12 into a phase appropriate for synchronization of phase control. The changed voltage is shaped by an AC filter 13. The filtering time constant of the filter 13 is made large enough to set a phase delay angle of almost 90°. As a result, the phase delay angle is always in the vicinity of -90° despite frequency change. Thus, a phase control synchronization signal can be produced by generating the output signal 11 of a ring counter 8  synchronized with the output of the AC filter. A signal delayed by about 90° by the AC filter 13 is converted by the AC transformer 12 into a phase convenient for the controlling of the thyristor converter and is therefore synchronized.

Title: Operation of blast furnace
Inventor: NAKAJIMA RYUICHI
IPC: C21B5/00
Filed: 1990-01-19
Abstract: PURPOSE:To prevent the worsening of furnace condition caused by the blow-by of gas in a blast furnace and to stabilize the furnace condition by continuously measuring blowing pressures in plural tuyeres or pressures at plural positions in shaft part of the blast furnace and throttling a hot air control valve at the position where the pressure abnormally lowers. CONSTITUTION:At the time of operating the blast furnace the blowing pressures in plural tuyeres are continuously measured and in the case the blowing pressure in the specific tuyere lowers at >=0.08kg/cm<2> for 5min, the blow-by in the shaft part above the tuyere is predicted to prevent the blow-by by throttling the hot air control valve of the tuyer, then the lowering of temp. in the furnace caused by the blow-by is prevented. As the other way, the shaft pressures in plural positions having equal interval on the circumference of the shaft part of the blast furnace are continuously measured and in the case the lowering of pressure comes to >=0.05kg/cm<2> within 5min, the hot air control valve for the tuyere of just below the measured position is throttled to prevent the blow-by at this part, and the operational condition in the blast furnace is stabilized.

Title: Driving of ribbon
Inventor: ISHIDA HIROSHI
IPC: B41J33/36
Filed: 1988-01-21
Abstract: PURPOSE:To prevent the number of printing characters per a unit length of a ribbon from decreasing by a method wherein a feed speed of the ribbon is varied in response to a printing element driving frequency of a printing wire or the like of a dot printer head. CONSTITUTION:A ribbon driving motor 2 is attached to a carriage 1 and its driving force is transmitted to a ribbon cartridge 4 via a driving gear 3. Further, the cartridge 4 has a film ribbon 6 built-in. The film ribbon 6 is drawn from a lower roll 7 and wound on an upper roll 9 by a ribbon feed roller 9. Since a feed speed (v) of the film ribbon to be wound by the ribbon feed roller 9 is in proportion to the number of revolutions of the ribbon driving motor 2. By making comparison with a presetted memory a driving frequency of a printing wire is predetermined according to a printing mode such as high density printing, or high speed printing, and the kind of a character string to be printed. Therefore, the number of printing per one ribbon cartridge can be increased while printing quality is kept at a constant level.
