IPC: H03K17/687
Filed: 2008-10-27
Abstract: <P>PROBLEM TO BE SOLVED: To drive an electric load including a capacitive component accurately with high power efficiency.  <P>SOLUTION: A target voltage waveform is output which repeatedly gradually increases and gradually decreases a voltage value within a prescribed voltage range, and an output voltage waveform to be output to an electric load is generated while switching a plurality of power supplies in accordance with the voltage value of the target voltage waveform. Furthermore, negative feedback control is performed in such a way that the output voltage waveform matches the target voltage waveform. When the output voltage waveform matches an application voltage of the electric load, the output voltage waveform is supplied to the electric load and when a target voltage is achieved, the output voltage waveform and the electric load are cut off. Thus, the electric load can be driven while collecting power accumulated in a capacitive component of the electric load. Further, since power sources are switched, a power loss at a circuit side can also be suppressed. In addition, since negative feedback control is performed in accordance with the target voltage waveform, the electric load including the capacitive component can be properly and efficiently driven.  <P>COPYRIGHT: (C)2010,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To enhance compression efficiency regardless of change in a flow rate condition from a low flow rate to a high flow rate, in a centrifugal compressor having a diffuser wall with vane.  <P>SOLUTION: A diffuser wall 18 with vane 26 is constituted to be moved in a direction getting close to or separated from a diffuser wall 17, according to a flow rate supplied from an impeller 4 to a diffuser 12. By the constitution, a difference in angle between a gas flow angle and an inlet angle of the vane 26 are maintained to be a certain level, even in the operation upon any of the flow rates from the low flow rate to the high flow rate. Since a whole width of a flow passage of the diffuser 12 is opened in high flow rate operation, the vane 26 does not block the flow of the gas flowing into the diffuser 12. Therefore, the compression efficiency in all of operation from the low flow rate to the high flow rate of the centrifugal compressor is enhanced.  <P>COPYRIGHT: (C)2010,JPO&INPIT
