Title: Reference voltage generation circuit, a/d converter and semiconductor integrated circuit
Inventor: KOBAYASHI YOICHIRO
IPC: H03M1/36
Filed: 1999-07-12
Abstract: PROBLEM TO BE SOLVED: To improve the accuracy of an A/D converter. SOLUTION: The reference voltage generation circuit is provided with capacitors C1 to Cn connected to the reference voltage supply terminals of respective comparators 13-1 to 13-n, constant current sources 12-1 to 12-n for charging the capacitors C1 to Cn and switching circuits 11-1 to 11-n for intermittently supplying constant currents to the capacitors C1 to Cn. From the viewpoint of variation in manufacturing, the properties of the capacitors C1 to Cn and the constant current sources 12-1 to 12-n are deviated from the design values similarly to that of other elements in the A/D converter. Consequently, the accuracy of A/D conversion can be improved by offsetting the manufacturing variation of elements in the comparators 13-1 to 13-n.

Title: Scanning type aligner
Inventor: AOTO KAZUAKI
IPC: G12B5/00
Filed: 1996-07-26
Abstract: PROBLEM TO BE SOLVED: To expose the entire region of a mask pattern on a photosensitive substrate, in the state of best focus.

Title: Optical fiber, light source device and system
Inventor: OKUNO TOSHIAKI
IPC: G02F1/35
Filed: 1997-07-24
Abstract: PROBLEM TO BE SOLVED: To efficiently generate non-linear phenomenon light such as supercontinuum(SC) light with wide wavelength width and with high flatness in the wavelength width and idler light etc., by providing a dispersion reduction area that wavelength dispersion is reduced from a positive value according to advance of pulse light in the main generation area of the non-linear phenomenon light. SOLUTION: In an optical fiber 310, the wavelength dispersion DIN on an incident end of high peak pulse light from a light amplifier 200 is the positive value, and the wavelength dispersion D is reduced linearly along the longitudinal direction. When the high peak pulse light is inputted to the optical fiber 310, since the inputted light advances on the area of abnormal dispersion that the wavelength dispersion is the positive value, the more pulse compression is advanced in the abnormal dispersion area with a late group speed the more the wavelength is longer.  Although the light of the wavelengths of a wavelength range of a certain degree are incorporated in a compressed light pulse, the light are affected strongly by an effect of four light waves mixture due to an optical Kerr effect while a dispersion value is changed from the positive to the negative, and the light with the wavelengths of the further wider wavelength range are generated. In such a manner, the SC light is generated.
