IPC: C10N60/00
Filed: 1999-02-01
Abstract: PROBLEM TO BE SOLVED: To obtain an unsulfided-alkali-metal-free additive for a lubricating oil by neutralizing a mixture of linear and branched alkylphenols with an alkaline earth metal base in the presence of a carboxylic acid and carboxylating the formed alkylphenate by the action of carbon dioxide. SOLUTION: An alkylphenol contains 35-85 wt.% linear one and 15-65 wt.% branched one. An alkaline earth metal base is selected among calcium oxide, calcium hydroxide, magnesium oxide, and a mixture thereof. The carboxylic acid used is a 50/50 mixture of a carboxylic acid with formic acid. The neutralization operation is performed at 200 deg.C. The pressure is gradually decreased to a subatmospheric pressure to remove the water of reaction. The molar ratio between the reactants is such that the alkaline earth base/alkylphenol ratio is 0.3:1 to 0.7:1. The obtained alkylphenate is carboxylated with carbon dioxide at 180-240 deg.C to such an extent that about 25% of the starting alkylphenol is converted into an alkylsalicylate to obtain the objective additive.

IPC: G01R33/07
Filed: 1989-03-15
Abstract: PURPOSE:To facilitate the determination of a position and to enhance signal accuracy by providing the attaching part of a Hall element at a molded frame, and attaching the Hall element to said attaching part. CONSTITUTION:When the cut part of a magnetic flux shutter 8 is located at a gap part G by the rotation of an internal combustion engine, the magnetic flux which is generated with a magnetic-flux generating member 7 forms mainly a magnetic path shown by a broken line A. The magnetic flux acting on a Hall element 2 is in a 'large' state. When the magnetic body part of the magnetic-flux shutter 8 is located at the gap part G, the magnetic flux which is generated with the magnetic-flux generating member 7 forms a magnetic path shown by a broken line B. The magnetic flux acting on the Hall element becomes a 'small' state. The change in magnetic flux in synchronization with the rotation of the internal combustion engine is imparted to the Hall element 2. An electric signal corresponding to the change in magnetic flux due to the Hall effect is generated. The electric signal is guided to an external circuit through a connector part 12, and the waveform is processed. Thus, the objective crank angle can be detected.

Abstract: PROBLEM TO BE SOLVED: To provide a wood composite board which is best suited as a flooring almost free from a recessed warping toward both ends of the flooring from the center part of its longitudinal direction and displays outstanding application properties. SOLUTION: A wood fiber board material 2 with a thickness of 0.5-2.0 mm and a specific gravity of 0.6-1.0 is applied to the front face side of a plywood base material 1 composed of a plurality of lumber veneers laminated adhesively to impart an appropriate rigidity to the surface of the plywood base material 1. At the same time, the generation of a recessed warping is suppressed by forming the wood fiber board material 2 thinly. Further, the fitting properties of the plywood base material 1 with a floor ground material are upgraded by applying a thin veneer 3 of conifer to the back face of the plywood base material 1. In addition, the trend of a projecting warpage is generated on the plywood base material 1 by the contracting force of the thin lumber veneer 3, so that the application properties are improved when the plywood base material 1 is fixedly nailed. Besides, the fiber direction of the wood veneers on both front and back face sides of the plywood base material 1 is made pliable widthwise.
