Title: Comparator with offset voltage automatic correction function
Inventor: OSHIMA SHUNZO
IPC: H03K5/08
Filed: 2000-03-24
Abstract: PROBLEM TO BE SOLVED: To provide a comparator with an offset voltage automatic correction function that automatically corrects an offset voltage so as to enhance the comparison accuracy thereby accurately detecting an over-voltage and a very small voltage. SOLUTION: In this comparator, a resistor R73 is used to set a prescribed potential so that an output of the comparator is inverted when a potential at a noninverting terminal is equal to a sum of a potential at an inverting terminal and a prescribed potential. In the case that a 1st condition holds, where a clock CLK with a very low duty ratio is at an 'H' level and an output of the comparator is at an 'L' level, analog switches S71-S73 switch off the connection of a 2nd voltage to the noninverting terminal and connect the noninverting terminal to the inverting terminal, in the case that the 1st condition does not hold, the switching is made inversely to the above.  In the case that the connection state corresponds to the 1st condition that is established and the output of the comparator is at an 'L' level, potential correction means (C71, Q79, D11 or the like) reduce the prescribed potential.

Abstract: PROBLEM TO BE SOLVED: To efficiently and easily impart high transmittance to a synthetic quartz glass by irradiating a synthetic quartz glass having a specific OH group content with a vacuum ultraviolet light having specific wavelength, thereby improving the transmittance of light of a specific wavelength range. SOLUTION: A synthetic quartz glass having an OH group content of <=50 ppm is irradiated with vacuum ultraviolet light having a wavelength of <=180 nm to improve the transmittance of light having a wavelength of η165 nm. The light source for the vacuum ultraviolet light is e.g. a xenon excimer lamp using xenon as a medium (main wavelength: 172 nm) and a fluorine laser using fluorine as a medium (main wavelength: 157 nm). The xenon excimer lamp is preferable in the case necessitating the improvement of the transmittance at wavelength of <=165 nm over a wide range and the fluorine laser is preferable from the viewpoint of productivity. The transmittance of synthetic quartz glass can be improved at a small dose of ultraviolet irradiation when the glass has a hydrogen molecule content of >=3×1016 molecules/cm3.  The glass preferably has a fluorine content of about 100-2,000 ppm and is essentially free from reduced-type defects.
