Abstract: PURPOSE:To provide a boost converter having a reduced size, which can operate at a high frequency and with a high efficiency and accompanied by a low noise. CONSTITUTION:Both the ends of a power supply 1 are connected by the series circuit comprising switches 5, 13. Both the ends of the transistor 13 are connected by the series circuit comprising a diode 12, a capacitor 14 and a coil 2. Both the ends of the capacitor 14 are so connected by a diode 16 as to constitute a parallel circuit. Also, both the ends of the series circuit comprising the capacitor 14, the coil 2 and the transistor 5 are connected by the series circuit comprising a diode 8 and a capacitor 10, and the voltage across the capacitor 10 is made the output voltage of a boost converter. The transistors 5, 13 are ON-OFF-controlled complementarily at a frequency corresponding to the output voltage of the boost converter. Thereby, in the ON-OFF transition time caused by the transistors 5, 13, the current flowing through the coil 2 can be made zero, and therefore, the boost converter can operate at a high frequency and with a high efficiency and accompanied by a low noise.

Title: Driving method for dot printer
Inventor: OMAE KOJI
IPC: B41J2/30
Filed: 1997-11-07
Abstract: PROBLEM TO BE SOLVED: To prevent print quality from deteriorating by feeding a coil intermittently with a minimum necessary release current and decreasing the release current being fed to the coil thereby preventing generation of heat and energy consumption of the coil from increasing while sustaining the printing force of a print hammer. SOLUTION: When a release current is fed intermittently to a coil 7 at a dot print hammer mechanism section, the current is interrupted temporarily at an almost flying timing and the necessary current can be reduced when a current 15 fed again. More specifically, the current is interrupted temporarily while floating the dot print hammer slightly from a nonprint position with the initial current supply, the dot print hammer can be released completely even if the magnitude of current being fed next is smaller than that of a conventional current. Since total current consumption can be reduced as compared with a conventional one, generation of heat from the coil can be prevented from increasing.

Title: Continuous annealing method for stainless steel strip
Inventor: HAGIWARA TOSHIYA
IPC: C21D9/56
Filed: 1995-11-27
Abstract: PROBLEM TO BE SOLVED: To uniformize the mechanical properties and the structure of a steel strip to be treated, at the time of welding a stainless steel strip to a plain steel dummy material and then applying continuous annealing, by controlling furnace temp. on the basis of the differences of heat absorptivity and emissivity between the stip and the dummy material at the time of passing the jointed part through the furnace. SOLUTION: A stainless steel strip, jointed to a dummy material, is annealed. When the set furnace temp. is adjusted to a proper temp. for the stainless steel strip and held constant as in a straight line 6 at this time, furnace temp. temporarily rises as in a curve 8, at the time of transfer from the dummy material to the stainless steel strip by plate feeding, and during the time interval until when conforms to the set value, from the difference of heat absorptivity between the dummy material and the steel strip, the temp. of the steel strip changes as in a curve 2 by the difference of emissivity and temporarily falls below the permissible temp. and, as a result, an incompletely annealed part is produced.  Therefore the set furnace temp. is controlled so that it is higher, as in a curve 5, by (α) deg.C at the time of the passing of the dummy material than that at the time of the passing of the stainless steel strip and lower by (α) deg.C at the time of the change to the steel strip. By this method, the furnace temp. and the steel strip temp. can be changed as in a curve 7 and a curve 1, respectively, and the steel strip can be annealed in a proper temp. range over the whole length.
