Title: Power supply apparatus for plasma arc utilizing equipment
Inventor: MORIGUCHI HARUO
IPC: H02M9/00
Filed: 1997-11-13
Granted: 2000-09-21
Abstract: A power supply apparatus for a plasma arc utilizing equipment providing an output current nearly equal to an input current includes a first converter for converting an AC voltage to a DC voltage. The DC voltage is converted to a high frequency voltage by an inverter. The output of the inverter is converted through a second converter to a DC voltage which is applied between a torch and a workpiece. A current detector detects an output current flowing between the second converter and the workpiece. A voltage detector detects an output voltage between the torch and the workpiece. A multiplier multiplies the output current and the output voltage to provide a signal representative of an output power. A comparator compares the output power representative signal with a first preset value. A signal from the current detector is applied to an error amplifier when the output power representative signal is smaller than the first preset value, and, otherwise, the output power representative signal is applied to the error amplifier. The error amplifier controls the inverter such that the signal applied to the error amplifier can be equal to a second preset value set by a setting device.

Filed: 1998-04-03
Granted: 2000-06-01
Abstract: A microstrip leaky-wave antenna with microstrip-aperture coupled feeding, comprises two layers of substrate. The upper layer is designed into a first higher order mode of microstrip line. The lower layer is designed into a fed standard planar wave microstrip. The intermediate metal is a common earthing and is etched to form an aperture so that it has the function of coupling the energy between the lower layer fed line and the upper layer leaky-wave antenna. The signal is fed from the lower layer microstrip line and, through the aperture, excites the upper layer of the first higher order mode of microstrip line thereby achieving irradiation. The invented antenna is an antenna that effectively realizes the characteristics of a first higher order mode of microstrip line, and provides the following benefits: avoiding exciting the dominant mode, without the need of designing a matching circuit, the fed circuit and the leaky-wave antenna capable of being separately optimized, the field type of the leaky-wave antenna will not be affected by the fed and downstream circuit(s), and without the need of switching circuit when connecting to or measuring a balance circuit. Therefore, the invented antenna can fully exhibit the wideband and scanning characteristics of a leaky-wave antenna.
