Abstract: PURPOSE:To obtain 1-octene in good selectivity by reacting butadiene with water in the presence of a Pd compound and phosphonium salt to give octa-2,7- diene-1-ol and hydrogenating octa-2,7-diene-1-ol to afford n-octanol and then dehydrating n-octanol. CONSTITUTION:Butadiene is reacted with water in the presence of a Pd compound (e.g. Pd acetylacetonato) and phosphonium salt expressed by the formula (X is OH, O-CO-OH or O-CO-R; R is hydrocarbon group; Y is allyl; Z is tri- substituted phosphonic group) at 60-80 deg.C to give octa-2,7-diene-1-ol, which is then hydrogenated in the presence of a hydrogenation catalyst to afford n- octanol or further n-octanol is dehydrated in the presence of an inorganic acid, etc., to provide 1-octene. In the reaction of the above-mentioned butadiene with water, induction period is not followed and toxicity of catalyst is not also brought out. 1-Octene is useful as a modifier for polyethylene.

Title: Washing machine
Inventor: MURAKAMI SUIKOU
IPC: D06F33/02
Filed: 1996-11-22
Abstract: PROBLEM TO BE SOLVED: To reduce time a required for intermediate dewatering in a good drainage condition. SOLUTION: At the initial state when a power plug is inserted, a time is reduced when increasing a rotation speed slowly at the initial stage of an intermediate dewatering (pattern a), and after a high speed dewatering rotation occurs, the rotation failure of a washing/dewatering drum caused by a foam resistance is detected according to a rotation speed after a specified time is elapsed. If a rotation failure is detected, a slow rising period is prolonged at the next intermediate dewatering (pattern b), and a detergent water dewatered is not trapped at the bottom of an outer drum and is easily drained. This allows a time required for intermediate dewatering to be reduced under the installation environment where a drainage from the outer drum is smoothed, and washing time can be reduced.  While, a time required for the intermediate dewatering is not reduced under the installation environment where a drainage is not smoothed, however, a rotation failure caused by a foam resistance can be prevented.

Abstract: PROBLEM TO BE SOLVED: To correct gradations by avoiding partial deterioration in contrast by deciding the area that image data belong to according to the feature quantities of respective pixels and correcting the pixel values of the image data according to a correction coefficient. SOLUTION: A feature quantity filter 9 detects and outputs feature quantities as to respective pixel values x(i,j) by using an image pickup result VT. An area decision filter 10 decides the area that the input image data belong to based on the detected feature quantities xmax(i,j) and outputs the decision result. A coefficient calculating circuit 11 generates contrast correction coefficients g(i,j) from a specific coefficient calculation function corresponding to the signal levels of low-frequency components r(i,j). Further, a multiplying circuit 12 multiplies the pixel values x(i,j) by the generated contrast correction coefficients g(i,j) to correct the signal level of the image pickup result VT by the contrast correction coefficients g(i,j) and output the result.
