Filed: 2001-02-09
Abstract: PROBLEM TO BE SOLVED: To provide a printing system where a digital camera and a printer are interconnected that has hardware having the same processing capability as that of conventional hardware to reduce the apparent print processing time. SOLUTION: When an operation section 105 of the digital camera 101 enters a print-state instruction, the printer 1 starts feed of paper, the digital camera 101 starts generating a yellow image signal that is a first recording color and transfers the generated signal to the printer, after the completion of its generation. While the printer conducts processing takes much time, such as paper feed and printing, the digital camera starts generation of magenta data that are a second recording color. Upon the receipt of the yellow data, the printer 101 immediately starts printing of a yellow image.

Title: Switching power circuit
Inventor: YASUMURA MASAYUKI
IPC: H02M3/28
Filed: 2001-03-05
Abstract: PROBLEM TO BE SOLVED: To reduce a design margin and ensure the breakdown voltage of switching a element at short-circuiting of a load. SOLUTION: In a composite-resonance converter, a self-exciting type is used for a primary-side voltage-resonance converter, and a control voltage variably controlled according to the level of a secondary-side direct-current output voltage is applied to a gate electrode of a MOSFET for a constant-voltage control. According to the state of conduction of the MOSFET, the capacitance to a self-oscillation circuit is varied, and a switching frequency is variably controlled. Thus, the switching element is switch-controlled by a combined control method wherein the conduction angle and the switching frequency of the switching elements are simultaneously varied.  In a load short-circuited state, or when power is applied, the switching frequency is controlled so as to be maximized within a control range or to exceed the maximum, and an excessive voltage is thereby prevented from being applied to the switching element.
