Title: Peak sample output circuit
Inventor: TOMIKAWA SHIGEO
IPC: G01R13/20
Filed: 1991-03-22
Abstract: PURPOSE:To obtain one peak (pulse) without generating output having two pulses with respect to pulse input. CONSTITUTION:An input signal is supplied to a positive peak detection circuit and a negative peak detection circuit. The output of either one of these peak detection circuits is supplied to a sample and hold circuit through a change-over switch. A positive pulse is detected from the output of the positive peak detection circuit by a pulse detection circuit 18. The output of the sample and hold circuit is compared with the input signal by a comparator 19. The output of the comparator 19 is set to the inclination polarity judging output of the input signal to be supplied to a switch control circuit 21 along with the output of the pulse detection circuit 18 and a sampling clock and, at the time of the positive inclination of the input signal, the positive peak detection circuit is connected to the sample and hold circuit and, at the time of negative inclination, the negative peak detection circuit is connected to the sample and hold circuit. When a positive pulse is generated in the case of the negative inclination of the input signal, the positive peak detection circuit is connected to the sample and hold circuit. The output of the comparator 19 and that of the pulse detection circuit 18 are supplied to the switch control circuit 21 through an OR circuit 28 and the output of the OR circuit 28 is processed as an inclination polarity judging signal.

Inventor: TANIMURA KOJI
IPC: B05D7/14
Filed: 1993-03-19
Abstract: PURPOSE:To enhance the close adhesiveness of an org. composite steel panel paint by forming a chromate film on the surface of a galvanized steel panel as a first film in specific quantity and forming a solid film of an epoxy resin containing SiO2 dispersed by boric acid and melamine cyanurate in specific amts as paint solids on the chromate film as a second layer. CONSTITUTION:A membrane org. composite steel panel is obtained by forming a chromate film 3 on the surface of a zinc plating film 2 of a steel panel 1 in quantity of 5-150mg/m<2> and applying a solid film of a water-soluble urethane modified epoxy resin 4 containing 10-40wt.% of SiO2 dispersed by hexametaboric acid and 0.5-10wt.% of melamine cyanurate as paint solids on the first layer in a thickness of 0.2-3.0mum as a second layer. When the adhesion amt. of the film 3 is below 5mg/m<2> as total chromium quantity, the close adhesiveness with the upper org. film is insufficient and, when the bonding amt. exceeds 150mg/m<2>, the close adhesiveness between the films is markedly lowered. When the thickness of the org. film is 0.2mum or less, corrosion resistance is insufficient and, when the thickness is 3.0mum or more, spot weldability is lowered.

Abstract: PURPOSE:To enable an excimer laser to be quickly controlled in power and to be improved in controllability of power by a method wherein an etalon and grating are provided together in an optical resonator, and the selection center wavelength is intermittently shifted so as to overlap the selection center wavelength of the etalon at overlapping control. CONSTITUTION:The center wavelength lambda and the center wavelength power P1 of a sample light detected by an oscillation center wavelength and center wavelength power detector 301 are inputted into a central processing unit (CPU) 302 which constitutes a wavelength controller. The CPU 302 shifts an etalon 101 in passing light center wavelength (selection light center wavelength) controlling the etalon 101 in angle or the like so as to set an output light or a sample light detected by the detector 301 to a required value in wavelength. An overlapping control is carried out in such a manner that the selection light center wavelength of a grating 106 is made to shift by a prescribed unit wavelength at a time so as to make the center wavelength power P1 detected by the detector 301 maximal enabling the selection center wavelengths of the etalon 101 and the grating 106 to overlap each other. Therefore, an excimer laser of this design is sharply improved in power controllability.
