Patent number: 6750637Abstract: A DC—DC conversion switching power supply is provided, including a plurality of DC—DC converters connected in parallel. A three-times frequency waveform which is generated from a three-times frequency waveform generation circuit, and is in sync with an oscillation frequency of the DC—DC converters is superimposed on a control voltage which is compared with a switching current signal in a current mode control circuit for controlling the DC—DC converters, or a signal proportional to the switching current signal to control a switching current pulse. Since superimposing the three-times frequency waveform which falls over one period increases the control voltage decreased by switch-on noise of the other DC—DC converter, malfunction at a switch-on phase of the other DC—DC converter, caused by the decrease of the control pulse width, is prevented.Type: GrantFiled: November 19, 2002Date of Patent: June 15, 2004Assignee: Matsushita Electric Co., Ltd.Inventors: Toshikazu Nagaki, Yoshio Mizutani

Patent number: 6552480Abstract: In a color cathode-ray tube with a shadow mask stretched and held by supporters while being provided with a tensile force, a member with a substantially L-shaped cross-section is used for each of the supporters, which is obtained by forming of a strip plate material having a middle part and thinner thickness-deviation portions on both sides of the middle part by rolling of a metal material; and then bending and deforming of the strip plate material in its width direction by roll forming to form a bent and deformed portion in the middle part. The supporter obtained by such a method can be reduced in weight while maintaining substantially the same strength as that of a conventional product, can be processed economically in relatively simple steps, and has less thickness variation. Therefore, an inexpensive color cathode-ray tube having stable qualities and causing less color unevenness can be provided.Type: GrantFiled: November 14, 2000Date of Patent: April 22, 2003Assignee: Matsushita Electric Co., Ltd.Inventors: Hideharu Ohmae, Susumu Okuji, Makoto Okuji
