Title: Field emission device driven by bipolar pulse power supply
Inventor: PARK JEA YEONG
IPC: H01J63/06
Filed: 2005-11-17
Abstract: <P>PROBLEM TO BE SOLVED: To provide a more efficient field emission device that has improved power consumption versus field emission efficiency and greatly improves the lifetime of a carbon nanotube used as an emitter.  <P>SOLUTION: In the drive system of the field emission device, a plus/minus bipolar type pulse power supply is applied to a gate by grounding a cathode. The pulse power supply has a constant duty ratio. When a plus voltage and a minus voltage are applied to the gate, electrons are emitted from the emitter made of the carbon nanotube on a cathode electrode 13 to the gate and from the carbon nanotube on the upper surface of the gate to the cathode electrode 13, respectively. While electrons are being emitted alternately at both the sides from the gate and the cathode electrodes 12, 13, electrons that are emitted by applying a high voltage to an anode are accelerated, and the accelerated electrons hit against a phosphor with which the upper surface of the anode electrode 22 is coated to emit light. Since the electrons are emitted alternately at both the sides of the cathode and the gate, the effective area of the emitter in the entire substrate area is doubled to obtain effect for enlarging an emission region. At the same time, the lifetime of the carbon nanotube emitter is extended, thus improving efficiency in a surface light-emitting device.  <P>COPYRIGHT: (C)2006,JPO&NCIPI

Title: Second-quadrant drive circuit and magnetically levitation control apparatus
Inventor: NAGANO YOSHIHIRO
IPC: H02M7/48
Filed: 2005-11-18
Abstract: <P>PROBLEM TO BE SOLVED: To provide a second-quadrant drive circuit capable of preventing an average value of electromagnet currents from being reduced more than an intended average current value.  <P>SOLUTION: A PWM signal generating circuit 32 generates signals G1, G2 based on a reference clock signal P generated in a clock generating circuit 31. The reference clock signal P input in a delay circuit 33 is reset to an off-state in synchronization with the rise of the next signal G1 after executing delay processing. Therefore, in a signal G11 input in a transistor 351 of the second-quadrant drive circuit 35, an off-signal of a signal G3 is inserted in an off-period just before the rise of the signal G1. On the other hand, the signal G2 is input in a transistor 352. As a result, the state that one transistor is turned off and the other transistor is turned on is inserted between the state that both the transistors 351, 352 are turned on and turned off.  <P>COPYRIGHT: (C)2007,JPO&INPIT
