Filed: 1995-05-01
Abstract: PURPOSE: To highly precisely control exposure on a reticle surface, and improve the contrast of a projection pattern image, by mixedly outputting luminous fluxes from two light sources which output luminous fluxes different in half wavelength width from light source means. CONSTITUTION: When a device to be manufactured necessitates the most critical resolution, the spectrum width of a laser light as exposure light is narrower the better. In this case, Ar ion laser 31 whose spectrum width is very narrow is practically used to the utmost. When a process is not so critical, the output from an excimer laser 1 is effectively used. The output from the Ar ion laser 31 is set to be necessary and minimum, and the output of the excimer laser 1 is applied to the residual exposure amount.

Title: Controlling method for changing running setting of a rolling milling machone
Inventor: BAN SEIICHI
IPC: B21B37/00
Filed: 1991-05-07
Abstract: PURPOSE:To reduce the predicted error of a load and to reduce plate thickness deviations on the outlet side by making variable mill rigidity control where a mill rigidity coefficient is changed and treated by a roll gap conversion. CONSTITUTION:When the actual mill rigidity coefficient takes a full line position, a roll gap is compensated by DELTAP2.alpha obtained by multiplying a tuning parameter alpha to the predicted error DELTAP2 of the load, rolling is performed by treating the mill rigidity coefficient as the value showing the mill rigidity coefficient of the rolling mill with a dotted line. In this way, even when an actual plastic curve is a dotted line Q2, a plate deviation DELTAh2 is to be generated by a rolled load P'2, but actually, the rolled load shows <P'2>, the plate thickness deviation is reduced by DELTAh2 and the plate thickness deviation takes DELTAh2-DELTAh'2.

Title: Side chain chlorination of aromatic compound
Inventor: MORINO YUZURU
IPC: C07C41/22
Filed: 1993-06-02
Abstract: PURPOSE:To obtain an aromatic compound having a chlorinated hydrocarbon side chain by subjecting a compound having an alkyl group or an alkoxy group on an aromatic ring to chlorination in the presence of a specific solvent. CONSTITUTION:The side chain of an aromatic compound having an alkyl group or an alkoxy group as a side chain is chlorinated by contacting chlorine gas in the presence of a radical initiator or under the irradiation of ultraviolet rays by the use of a chlorinated benzotrifluoride as a solvent. The chlorinated benzotrifluoride is used as much as 0.5-50 pts.wt. to 1 pts.wt. of the compound to be chlorinated. The chlorinated benzotrifluoride is stable in the chlorination reaction and has a high solubility to an aromatic compound. Therefore, the required amount of the solvent is lowered and the solvent can be recycled. Since the chlorination reaction using the chlorinated benzotrifluoride is carried out almost in the same conditions as the case of carbon tetrachloride solvent, the conventional reaction vessel can be used. The aromatic compound having chlorinated side chain is a useful raw material for pharmaceuticals, agrochemicals, functional materials, etc., after hydrolysis, fluorination, etc.

Title: Nitrogen oxide low-generation premixing burner
Inventor: OTA KIYOSHI
IPC: F23D14/08
Filed: 1993-06-02
Abstract: PURPOSE:To restrain the generation of nitrogen oxides by effective recirculation combustion. CONSTITUTION:Burner port rows 2 comprising a large number of burner ports 3 are formed on a metal burner port plate 1 and an exhaust gas passage interval 4 is formed between adjacent burner port rows 2, and the plate 1 is formed into a corrugated shape, which plate is disposed in a burner port section 5 of a premixing burner. When a premixed gas is introduced into the section 5, the premixed mixture is ejected from each of the burner ports 3 so that flames 6 are formed. The flames 6 are generated in each row 2; however, since there is the interval 4 between the adjacent rows 2, when the premixed gas is ejected from each port 3, good negative pressure is formed in the interval 4 and part of combustion gas is drawn by ejection energy so that effective recirculation combustion is performed, whereby the generation of nitrogen oxides can be restrained. Such recirculation combustion is performed in each row 2; however, since a large number of ports 3 are formed in the row 2, the formed flames are numerous divided-flames. Consequently, thermal expansion is absorbed and the surface of burner becomes larger and hence recirculation can be performed effectively.

Abstract: PURPOSE:To improve accuracy of detecting the ignition timing so as to stabilize the engine output efficiency, by providing the ignition timing detector with a photoelectric conversion element which converts the combustion light passing the light detecting member into an electricity, and also with a filter means which shields the infrared light in the combustion light. CONSTITUTION:A light detecting member 1 transmits the combustion light in the combustion chamber into a photoelectric conversion member 3 which, in turn, converts the light signal from the light detecting member 1 to an electric signal. An infrared light shielding filter 10 has a function to screen off the waves with a wave length larger than 600nm. The signal detected and recognized by a light detector 100 is supplied to an electric control circuit 20 including an ignition timing detecting circuit 21 and this circuit drives a fuel injection pump 22. Thus, as the stabilized accurate ignition timing can be detected even when infrared light is emitted during high revolution and high load, fuel control is executed without failure constantly and thus engine output efficiency can be stabilized.
