Title: Controlling method for multiple pwm converter
Inventor: TAMURA HIROAKI
IPC: H02M7/497
Filed: 1987-11-30
Abstract: PURPOSE:To promote its compact and lightweight design at a low cost by making the operating current (the maximum braking-current) for a power semiconductor equal among unit converters. CONSTITUTION:A controller of a triple-three phase PWM converter is equipped with AC current transformers (ACCT) 71-72, PWM controlling circuits 81-83 and a current operational circuit 104. A command value of the DC intermediate circuit voltage determined by a voltage setting 101 is compared with the output of a DC voltage detector 102 and is controlled by a voltage blind controller 100. The voltage blind controller 100 outputs the converter power Pc to the unit converter current operational circuit 104 so as to keep the voltage of the DC intermediate circuit constant. The operational circuit 104 derives a fundamental wave resultant current command value of a secondary winding from the converter power and the detection voltage ES. In addition, from the command value, a fundamental wave current command of each unit converter 41, 42, 43 is decided respectively. Accordingly, the maximum breaking-current value of each element can be equalized.

Abstract: PROBLEM TO BE SOLVED: To facilitate the detection of ink sagging or ink omission by moving a bar code printed at a unit of a print element in the case of printing a plurality of bar codes by a printing means for scanning in a direction substantially perpendicularly to the arraying direction of printing elements and printing. SOLUTION: When the part of a check digit 4 and less significant digit are removed in a bar code 1, ten bar codes of sequential numbers are the same. When the part of the digit 4 and two less significant digits are removed, the hundred bar codes of sequential numbers are the same. Then, the bar code 6 to be printed next to the code 1 is printed at the position moved by one (1 dot) of the printing element from the code 1. Thus, when the bar code is moved at the distance of the bar of the maximum width, the elements have conducted all the operation modes, and the elements can be checked from the printed bar codes during the period.

Inventor: SUGIURA AKIO
IPC: G06K7/10
Filed: 1991-11-15
Abstract: PURPOSE:To reduce the power consumption of a power supply means even in a read waiting state. CONSTITUTION:When the absence of a bar code is decided, the timer of a processing part 7 is started. Then the output state of the lighting signal applied to a driving part 2 is switched to an intermittent output state (a) set by a blinking pattern 1 from a continous output state when it is decided that the starting time (t) of the timer is larger than the first prescribed time T0. When it is decided that the time (t) is larger than the second prescribed time T1, the output state of the lighting signal is switched to an intermittent output state (b) set by a blinking pattern 2 having its intermittent time longer than the pattern 1 from the state (a). Thus the turn-off time is gradually increased as the time elapses so that the power consumption of a power supply means is gradually reduced.

Filed: 1988-11-29
Abstract: PURPOSE:To improve a high frequency characteristic and recording/reproducing speed by forming a second magnetic layer in a flat shape on the upper surfaces of a first rising part and a second rising part in one magnetic layer. CONSTITUTION:A lower magnetic layer M1 has a first rising part M1b and a second rising part M1c which rises from a base plate part M1a at the almost same height as the first rising part. An upper magnetic layer M2 faces to the upper surface of the first rising part M1b in the lower magnetic layer with interposing a gap layer G and forms a joint part in an interval with this lower magnetic layer M1 on the upper surface of the second rising part M1c in the other magnetic layer.
