Abstract: A cowl top cover is disclosed that can be placed flush with a windshield and that makes it possible to efficiently absorb an impact load by appropriately allowing the windshield to deform, when the windshield is subjected to the impact load. The cowl top cover according to the present invention includes: a glass-parallel portion including an outer surface that is flush with the windshield at a rear end portion of a cover-main-body portion. The glass-parallel portion includes at least single linear fragile portion having a reduced thickness of the glass-parallel portion along the vehicle width direction. The fragile portion is configured to be deformable or breakable when the cover-main-body portion is subjected to a load equal to or greater than a predetermined magnitude.

Abstract: A cowl-top cover capable of restraining a resistance force with respect to a load from a direction crossing a front glass face while improving its related appearance is provided. A cover main body portion is provided with a cover mounting portion adapted to be inserted into and engaged with, in a direction crossing a front glass face, an engagement receptacle portion disposed along a longitudinal direction at an edge part of a front glass from one end part in the longitudinal direction. The cover main body portion is provided with a low rigidity portion along the longitudinal direction at a position spaced from the cover mounting portion to an opposite side to the front glass.

Abstract: A sub air chamber provided around outer circumferential surface of a well of a rim of a vehicle wheel includes an upper plate and a lower plate connected at edges thereof which are fitted into channels in first and second vertical wall surfaces formed on the rim. At least one of the upper plate and the bottom plate has orthogonally and diagonally aligned beads to vertical walls, extending in a circumferential direction of the wheel, supporting the sub air chamber, connecting parts locally connecting the upper plate and the bottom plate. The sub air chamber has a protruding part for communicating the sub air chamber with the tire air chamber and serves as a stopper of the sub air chamber.

Abstract: An instrument panel includes a panel body and a joint member. The panel body includes a core member and an outer layer that covers the core member, and is formed by reaction injection molding. The panel body includes a meter installed portion. A recess of the meter installed portion becomes an undercut at the time of molding. A core member is provided with a deformable portion which is elastically deformable. The molded panel body can be demolded by deforming the deformable portion. There is no need to provide a slide core with a molding die. A deformation of the deformable portion is prevented by installing the joint member onto the demolded panel body. According to the instrument panel, it is possible to improve a product quality and reduce manufacturing cost.

Abstract: A process for improving the fluidity of hydrocarbon fractions by dewaxing thereof. In the present process, hydrocarbon fractions are contacted with hydrogen in the presence of a specific type of catalyst, thereby lowering the pour point of the hydrocarbon fraction. The catalyst comprises a specific type of zeolite which is defined by a specific X-ray diffraction pattern and which has a predetermined range of mesitylene adsorption of not less than 1.6 wt %. The zeolite catalyst is obtained by providing an aqueous reaction mixture of SiO.sub.2, Al.sub.2 O.sub.3, an alkaline source as OH.sup.-, and a carboxyl group-containing organic compound having the following composition:______________________________________ SiO.sub.2 /Al.sub.2 O.sub.3 20-60 H.sub.2 O/SiO.sub.2 5-100 OH.sup.- /SiO.sub.2 0.1-0.35 ______________________________________and reacting the mixture until crystals are produced. Advantageously, the ratio of the carboxyl group-containing organic compound to aluminum oxide is about 1.0 to 100.
