Title: Discharging lamp lighting device
Inventor: NISHI KENICHIRO
IPC: H05B37/03
Filed: 1997-02-21
Granted: 2000-02-01
Abstract: This invention is to eliminate detection of wasteful lamp current due to performing feed back control for the full range of light adjustment signals, widen a dynamic range, and enhance detection precision of lamp current. A current detecting circuit 5 detects current passing the discharging lamp 4 and outputs the current as lamp current signal to in the feedback control circuit 7. Feedback control circuit 7 would amplify the difference between lamp current signal A and light regulating signal B and output the amplified signal D to an adder 12. Adder 12 would add the amplified signal D and light regulating signal B for forming control signal E and feedback to a high-frequency power source 2; but when comparison circuit 15 detects the light regulation degree with respect to the full light of the light regulating signal is above 40~60%, the feedback circuit is disconnected by using a switch 13 between an error amplifier circuit 9 and adder 12 to stop the feedback control and the range in which feedback control is performed for the full range of the light regulating signal B is limited and the detection range of the lamp current signal is narrowed, while a dynamic range is widened relatively, and the detection accuracy of the lamp current signal is enhanced. Also, for the discharging lamp ignition device having light regulator, normal discharge lamp would not be misjudged as one at the end of life, and the damage of the discharge lamp lighting device can be prevented by correctly determining the end of life of the discharge lamp. When the light level of a discharge lamp 4 is less than a predetermined value, first and second reference voltages 8a, 8b are switched by a two-stage switching circuit 9. A comparator 7 compares the detected voltage 6 of the discharge lamp 4 with the first reference voltage 8a or with the second reference voltage 8b and, if the voltage of the discharge lamp 4 is higher, a control signal 12 for shutting off or reducing the output of a high frequency power supply 2 is fed from a control circuit 10 to the high frequency power supply 2.

Title: Improved reverberatory screen for a radiant burner
Inventor: GRAY PAUL E
IPC: F23D14/16
Filed: 1998-01-26
Granted: 2001-02-21
Abstract: The present invention relates to porous mat gas fired radiant burner panels utilizing improved reverberatory screens. The purpose of these screens is to boost the overall radiant output of the burner relative to a burner using no screen and the same fuel-air flow rates. In one embodiment, the reverberatory screen is fabricated from ceramic composite material, which can withstand higher operating temperatures than its metallic equivalent. In another embodiment the reverberatory screen is corrugated. The corrugations add stiffness which helps  to resist creep and thermally induced distortions due to temperature or thermal expansion coefficient differences. Asan added benefit, it has been unexpectedly discovered that the corrugations further increase the radiant efficiency of the burner. In a preferred embodiment, the reverberatory screen is both corrugated and made from ceramic composite material.

Title: Method for measuring semiconductor device current density caused by kink effects
Inventor: YE MENG-LIN
IPC: H01L21/66
Filed: 1998-06-26
Granted: 2002-11-11
Abstract: A kind of method for measuring the influence degree of kink effects for the first semiconductor device includes the following steps. At first, the second and the third semiconductor devices having the same channel length and different channel widths are selected. A voltage is then added to the drain of each device, and the threshold voltage of each semiconductor device is measured. The threshold voltage is added to the gate of each semiconductor device, and a current flowing from the source to the drain is measured. A slope is then obtained from dividing the differential value of the first drain current by the differential vale of the first channel width. The differential vale of the first channel width is obtained from the difference between the second and the third semiconductor device channel widths. The differential value of the first drain current is obtained from the difference between the drain/source currents of the second and the third semiconductor device. A parasitic current can be obtained by subtracting a product, which is obtained by multiplying the slope with the first channel width, from the first drain/source current. At last, the influence index of the first semiconductor kink effect is obtained by dividing the parasitic current by the channel length of first semiconductor device.
