IPC: H02J7/35
Filed: 2007-01-17
Abstract: <P>PROBLEM TO BE SOLVED: To solve such a problem that when solar radiation quantity is constant, output power from a solar battery changes like a P-I characteristic curve 31 according to output current, and when the extracted output current is I<SB>M</SB>, the maximum output P<SB>M</SB>at this solar radiation can be extracted, while the current is not necessarily controlled in such a manner conventionally, the extracted power was smaller than the maximum output P<SB>M</SB>, and the capability of the solar battery is not fully utilized.  <P>SOLUTION: A line obtained by connecting the maximum output points M of the P-I characteristic curves 31 for various solar radiation quantity is a maximum output point line 30. When current power generation state falls in a first region 32 where the maximum output point line 30 is larger than the P-I characteristic curve 31 (for example, Y point), the current is reduced to be close to the maximum output point M. Conversely, when it falls in a second region 33 where the line is smaller (for example, A point), the current is increased to be close to the maximum output point M. Thereby, the maximum output can be extracted. Even when the solar radiation quantity changes, the maximum output can be always obtained through the control as following a change in the solar radiation quantity.  <P>COPYRIGHT: (C)2008,JPO&INPIT

Title: Electric discharge machining apparatus
Inventor: MURAI MASAO
IPC: B23H1/02
Filed: 2007-01-18
Abstract: <P>PROBLEM TO BE SOLVED: To reduce the effect of the stray capacity of the cable of a voltage measuring circuit upon the surface roughness of a machined surface in finish machining.  <P>SOLUTION: Voltage between electrodes is measured by connecting a voltage measuring circuit 4 between an electrode 1 and the electrode of a workpiece 2 by means of a parallel reciprocation cable 3 via a resistor R. The parallel reciprocation cable 3 is formed such that two lead wires are so fixed as to be in parallel with each other at a constant interval with insulating and flexible materials, such as rubber and resin, like the feeder wire for a TV antenna. The stray capacitance of the parallel reciprocation cable is reduced by widening the interval between the two lead wires of the cable. As a result, the high frequency voltage in finish machining can be measured by the voltage measuring circuit without being attenuated. Further, the pulsation of the voltage to be input to the voltage measuring circuit can be suppressed because the resistor R is inserted therein. Because of the reduction of the stray capacitance, the electric discharge energy in the finish machining can be suppressed to be small, and the roughness of the machined surface can be improved.  <P>COPYRIGHT: (C)2008,JPO&INPIT
