Inventor: TAKAHASHI YASUO
IPC: H04N7/015
Filed: 1996-04-02
Abstract: PROBLEM TO BE SOLVED: To separate a chrominance signal and a horizontal reinforced signal from a multiple signal. SOLUTION: A chrominance signal and a horizontal reinforced signal are extracted from each inter-frame difference signal through a 1st filter 103, 105, 115, 117, 119 and a 2nd filter 103, 105, 107, 109, 111. Respective vertical high frequency components of the chorominance signal and horizontal reinforced signal are extracted through a 1st vertical low pass filter(LPF) 123, 125 and a 2nd vertical LPF 129, 131 and outputted to the input terminal A of a comparator 137 and an adder 135. The adder 135 adds a fixed value α to the vertical high frequency component of the horizontal reinforced signal and outputs the added signal to the input terminal B of the comparator 137, which outputs a high level signal to the control terminal of a switch 139 when the signal of the terminal B < the signal of the terminal A or outputs a low level signal in the opposite case.  The switch 139 selects the horizontal reinforced signal when the signal inputted to the control terminal. is low or a value '0' at the time of inputting a high signal and outputs the selected signal to a subtractor 141. The subtractor 141 executes subtraction processing between the inter-frame difference signal and the output of the switch 139 and outputs a chrominance signal.

Title: Inspection method for optical material for excimer laser
Inventor: KUZUU SHIN
IPC: H01S3/08
Filed: 1993-03-17
Abstract: PURPOSE:To provide a method for selecting such a material as causing no absorption, when excimer laser light is transmitted for a long time by irradiating a synthetic silica glass with X-rays, easily in a short time. CONSTITUTION:Silicon tetrachloride is subjected to hydrosis in hydrogen flame and deposited directly to produce a synthetic silica glass sample which is then irradiated with excimer laser of KrF, ArF, F2, etc., or X-rays. In this regard, a linear relationship exists between absorption coefficients alpha derived through irradiation. Extent of absorption when the sample is subjected to 10<6> shots (about 2.8 hours) of 100HZ KrF excimer laser, for example, can be predicted by irradiating the sample with Rh target X-rays of 50mA, 5OkV for 10-15 min in the vacuum of about 10<-2>Torr. When X-rays are used, generation of 220nm absorption band can be decided in a short time and the extent of absorption can be predicted when the sample is irradiated with excimer laser having photon energy of 5eV or above. Consequently, a material causing no absorption even after transmission of excimer laser for a long time can be selected.
