Abstract: PURPOSE:To enable to perform the effective wide-band lighgt and electricity negative feed-back by preventing the leakage of the current from the light emitting element into the light-detecting element by separating a drive current path of the light emitting element from a light-detecting current path of the light- detecting element. CONSTITUTION:A light-detecting element consisting of PD20 is formed in annular shape and monolithicly on one surface of a light emitting element consisting of LED10. The light output from an active region 14 is detected partly in the PD20 as well as is outputted to the outside partly through a light penetrating part 30 or the outside of an electrode 17 and enters into the optical fibers 1-40. In this constitution, one electrode 17 of the LED10 is formed inside a light-detecting part 25a of the PD20 and one electrode 24 of the PD20 is arranged outside the light-emitting part 25, so that the electrode path 30 of the LED10 is present inside the current path 40 and these are independent of each other.

Abstract: PURPOSE:To obtain a resin molded body prevented from the separation of an inorg. filler and a resin by molding the resin molded body from a composite material consisting of the inorg. filler, the resin and a plasticizer in a specific ratio. CONSTITUTION:A resin molded body contains a base resin composed of a thermoplastic resin having an MW of 50,000-1,000,000, an additive resin composed of a resin having an MW of 1,000-50,000, an inorg. filler and a plasticizer. The ratio of these components is set so that the additive resin is 0.5-100 pts.wt. and the plasticizer is 0.1-10.0 pts.wt. per 100 pts.wt. of the base resin and the inorg. filler is 5-200 pts.wt. per 100 pts.wt. of the sum of the base resin and the additive resin. Even when short-time molding is performed using this composite material, the separation of the inorg. filler and the resins is not generated and a uniform resin molded body is obtained. When the MW of the base resin is smaller than 50,000-1,000,000, the strength of the molded body can not held and, when said MW larger than 50,000-1,000,000, the flowability of the composite material becomes bad. When the MW of the additive resin is smaller than 1,000-50,000, the additive resin is decomposed and, when said MW is larger than 1000-50,000, flowability at the time of molding is not enhanced and the inorg. filler is crystallized out on the surface of the molded body.

Abstract: PURPOSE: To obtain the titled compound useful as an intermediate for a perfume, an insecticide or a medicine, readily in a short stage, by condensing a readily available acetoacetic ester with a monohalogenoacetone, and saponifying and decarboxylating the condensate.  
     CONSTITUTION: An acetoacetic ester expressed by formula I (R is alkyl) is reacted with a monohalogenoacetone expressed by formula II (X is Cl, Br or I) in the presence of a base, e.g. an alkali metallic hydroxide or an alkali metallic alkoxide, in a polar solvent, at -10W25°C, to prepare 2-acetyllevulinic acid. When a polar nonaqueous solvent is used as the reaction solvent, the solvent is eliminated, and the 2-acetyllevulinic acid is saponified in the presence of a mineral acid, alkaline hydroxide, etc., and subsequently decarboxylated, to give the aimed compound. A mineral or organic acid which enables the simultaneous decarboxylation, may be preferably used for the saponification. When water is used as the reaction solvent, the saponification occurs at the same time with the acetonylation.

Abstract: PROBLEM TO BE SOLVED: To eliminate the variation of excellent linear luminance by synchronizing the polarization control signal of an AC polarization are discharge lamp with the color channel exposing timing signal of a CCD line sensor. SOLUTION: A scanner illuminating system 22 is additionally provided with an AC polarization are discharge lamp 36 driven by a square wave (Vlamp and Ilamp ) generated by an electronic lamp ballast 38.
