  • Patent number: 5423300
    Abstract: An internal combustion engine according to this invention is provided with intake ports each of which is formed to guide a flow of inducted air in a particular direction. Each intake port includes, in the vicinity of its corresponding intake opening to a combustion chamber, a bent port portion bent at a greater curvature than a port portion on a side upstream of the bent port portion. The bent port portion has a greater inner diameter than the inner diameter of the corresponding intake opening, whereby air can be inducted in a sufficient amount without deterioration to the directing function for air to be inducted into the combustion chamber.

  • Patent number: 5384368
    Abstract: The present invention relates to a process for producing water absorbent resin comprising a step of adding a high-molecular crosslinking agent which has at least 2 azetidinium salt groups in the molecule and has at least 1000 weight-average molecular weight to the water absorbent resin paticles having carboxylic groups and carboxylic acid salt groups and a step of efficiently crosslinking the vicinity of the surface of the water absorbent resin particles. In the process for producing water absorbent resin according to the present invention, the use of high-molecular crosslinking agent achieves less permeation of the crosslinking agent into the water absorbent resin particles and enables efficient crosslinking of the vicinity of the surface of the water absorbent resin particles. Consequently, the water absorbent resin having high water absorbency both under pressure-free state and under loading can be manufactured.

  • Patent number: 5379661
    Abstract: A loading cam device is constructed of a first cam surface, a second cam surface, a ring-shaped retainer disposed between the first and second cam surfaces and defining pockets at angular intervals, and rolling members maintained in contact with the first and second cam surfaces while rotatably held within the respective pockets. The circumferential width of each pocket is smaller at each side of the retainer but greater along a thicknesswise central axis of the retainer, both compared with the outer diameter of the rolling members. As an alternative, the thickness of the retainer is a little smaller at a location adjacent to each pocket but significantly smaller at a location remote from the pocket, both compared with the thickness the outer diameter.
