Title: Inverter control power source
Inventor: KASHIMA TAKAYUKI
IPC: H02M7/537
Filed: 1984-12-19
Abstract: PURPOSE:To suppress the current variation when a diode between the drain and the source is reversely recovered by inserting a current limiting reactor to the DC input side of an inverter. CONSTITUTION:An arc welding inverter control power source using power MOSFETs (FET) T1-T4 has a rectifier 1, a rush current preventing and smoothing reactor 2, a smoothing condenser 3, and a bridge type inverter 4, and supplies the high frequency AC output of an output transistor 5 through a rectifier 6 and a smoothing reactor 7 to a welding electrode 8. The output of a current detector 11 is compared with the set signal of an output current setter 12, and an FET is alternately controlled ON or OFF by a pulse width controller 13 so that the output current becomes constant. In this case, a current limiting reactor 14 and a flywheel diode 15 are provided at the DC input side of the inverter 4. Thus, since the abrupt reverse recovery between the drain and the source is suppressed, a stable operation can be performed without damaging the FET.

IPC: H04N5/202
Filed: 1996-10-08
Abstract: PROBLEM TO BE SOLVED: To completely absorb the variance of transmissivity of a liquid crystal light bulb by preparing a look-up table, which is used when the form of an input image signal is decided and an automatic gamma correction is applied to the image signal. SOLUTION: Every projection display device has a look-up table 2252, that is adaptive to a liquid crystal light bulbs 925 R, G, and B mounted on the display device. Thereby, the variance of transmissivity of the bulb 925 R, G, and B, if caused among these display devices, is completely absorbed. It is not necessary to prepare the look-up tables for all video signals that may possibly be inputted in the NTSC, PAL/SECAM and PC modes, etc. Instead, the signal forms are decided, when the video signals are switched, and the table 2252 is automatically updated. Thus, a single table 2252 is sufficient for each color.
