  • Patent number: 7684922
    Abstract: A cam sensor is provided in a position opposing one surface side of a cam driven sprocket in a valve timing control device. When the valve timing control device is in a high revolution state, a weight is pivoted by centrifugal force caused by the rotation. This allows a projection at the weight to be detected by the cam sensor. In this case, for each rotation of the valve timing control device, the projection of the weight passes the detectable position of the cam sensor and a pulse is generated in a cam signal to be transmitted from the cam sensor to an ECU.

  • Patent number: 7673603
    Abstract: When an engine operates at low engine speed, the tip end of a cam nose of an intake cam is at a second position. As the engine speed increases and exceeds a first engine speed, the tip end of the cam nose of the intake cam moves to a first position. When the engine operates at high engine speed, the tip end of the cam nose of the intake cam is at the first position. As the engine speed decreases and becomes lower than a second engine speed smaller than the first engine speed, the tip end of the cam nose of the intake cam moves to the second position different from the first position.

  • Publication number: 20090114175
    Abstract: During a low revolution period, centrifugal force applied to a weight is small and therefore the rotating operation of the weight is restricted. This prevents a lock pin from being fitted to the lock pin fitting hole of a floating cam portion, and the floating cam portion idles around a cam fixing shaft. During a high revolution period, centrifugal force applied to the weight increases, and therefore the weight rotates around the rotation shaft. In this way, the tip end of the lock pin is fitted to the lock pin fitting portion of the floating cam portion. Therefore, during the high revolution period, the floating cam portion is fixed with respect to the rotating direction of the variable valve system by the lock pin.

  • Patent number: 5967904
    Abstract: A golf club head made of a hollow metal comprising a face and a body, wherein at least the face is made of a rapidly solidified Al-based alloy having a high strength, high elasticity and light weight. This golf club head makes it possible to stroke a ball without elastic deformation of its face and also to fly the ball farther with the initial speed thereof maintained, by using the Al-based alloy at least in the face. In addition, the use of the Al-based alloy makes it possible to form a large head and a long shaft so that balls can be stroked to fly over a long carry in an accurate direction.

  • Patent number: 5431214
    Abstract: A cooling mold has first and second water cooling jackets provided inside the mold. A primary cooling water jetting mouth is located at a distance between 15 and 40 mm from the meniscus of the molten metal. A secondary cooling water jetting mouth is located at an interval of 20 to 45 mm between a contact point of a primary jet of cooling water and another contact point of a secondary jet of cooling water on an ingot. The primary and secondary cooling water jetting mouths are respectively set at an angle of 15 to 30 degrees and of 30 to 60 degrees relative to the ingot surface. The primary jet of cooling water from the primary mouth impinges on the molten metal cooled in the cooling mold at a distance from the meniscus to establish a transition boiling zone and a film boiling zone. The secondary jet of cooling water impinges on initial zones of the transition boiling zone and the film boiling zone to break-out a vapor film.

  • Patent number: 5306730
    Abstract: A botulinum toxin neutralizer comprising at least one fatty acid having the number of carbon atoms of at least 12. Such a fatty acid may be any of saturated fatty acids such as lauric acid, myristic acid, palmitic acid, stearic acid, nonadecanoic acid, arachidic acid, and behenic acid or any of unsaturated fatty acids such as oleic acid. The toxin neutralizer acts as if it were an antagonistic receptor for botulinum toxin and, when encountering botulinum toxin in human body, directly combines with the toxin and disables the toxin from combining with the neuromuscular tissues of human body to prevent the outbreak of botulism. The toxin thus neutralized and affixed to the botulinum toxin neutralizer is excreted from the human body. The botulinum toxin neutralizer can be manufactured easily and economically from a naturally occurring glyceride and is thus far less costly then the known antitoxin of ganglioside GT1b produced from bovine brain.
