  • Publication number: 20090266638
    Abstract: When activated, an actuator causes a piston rod in a cylinder to move forwards so as to support a receiving member for receiving an object to be protected. A lock mechanism for restricting a backward movement of the piston rod includes a lock ring which is accommodated in an accommodating groove on a piston portion and a locking stepped portion on the cylinder side. The locking stepped portion includes a locking and restricting surface and an outer circumferential restricting surface.

  • Publication number: 20090242308
    Abstract: A pedestrian protection system is mounted in the front portion of a vehicle, and includes a controller, a forward movement holding mechanism controlled in actuation by the controller, and a contact body that a pedestrian can contact. The controller, when having predicted a collision of a pedestrian with the vehicle based on a signal from a collision predicting sensor, actuates the forward movement holding mechanism to cause a forward movement of the contact body, and based on a signal from a turn sensor when the forward movement holding mechanism carries out an upward rotation or a downward rotation at the time of contact of the forwardly moved contact body with a pedestrian, controls actuation of the restraint body so as to correspond to a pedestrian moving to a front upper side of the vehicle and a pedestrian moving to a front lower side of the vehicle, respectively.

  • Publication number: 20090243268
    Abstract: The occupant protection system includes a catching body that is housed in a housing located between a near-by seat and a distant seat for upward deployment and a support body that supports the catching body. The catching body covers the impact side of a distant-side occupant to catch the occupant moving toward the impacted lateral and includes a distal end acting as a free end swingable in a left and right direction. The support body is located on a side of the near-by seat close to the impacted lateral for deployment to support the catching body when the catching body swings toward the impacted lateral after receiving the distant-side occupant.

  • Publication number: 20090223360
    Abstract: An actuator includes a cylinder, a piston rod which moves forwards within the cylinder and a lock mechanism for restricting a backward movement of the piston rod that has moved forwards. The piston rod includes a piston portion and a support rod portion which is made to extend from the piston portion. The lock mechanism includes an annular elastic element which is disposed with an inner circumferential edge made to project further radially inwards than an inner circumferential surface of the cylinder and a groove which is disposed so as to extend along an outer circumferential surface of the piston portion for the annular elastic element to be fitted therein.

  • Publication number: 20090216427
    Abstract: Methods and systems for controlling an internal combustion engine are provided. One example method may include closing an intake valve later during a cylinder cycle than a timing with which an amount of air inducted into a cylinder from an air intake passage would be maximized, and earlier during the cylinder cycle as a desired amount of air to be inducted into the cylinder increases, while an engine is operating at a given engine speed. The method may further include closing the intake valve earlier during a cylinder cycle as the engine speed increases when the desired amount of air to be inducted into the cylinder is at a maximum.

  • Publication number: 20090084620
    Abstract: An actuator AE1 includes a lock mechanism R1 configured to fill a gas G generated by operating a gas generator 35 at inside of a cylinder 22 and moving forward a piston 38 along with a support rod 40 for restricting a rearward movement of the support rod moved forward. The support rod 40 is arranged to be able to absorb a kinetic energy of a protection object person and capable of being plastically deformed when the protection object person is received by a receiving member after having been moved forward. A lock mechanism R1 is constituted by a diameter enlarging deformed portion 42 arranged at a piston and a locking stepped portion 24 capable of restricting the rearward movement of the piston.

  • Publication number: 20080247773
    Abstract: New information can be added to an information medium, and the information is certainly managed such that the information is not leaked when the information is outputted. An image reading section 2 reads the information medium and inputs images including a unique image and a code image. A detecting section 64 of a code processing section 63 determines the code image and the unique image from inputted images to detect the code image. An extracting section 65 restores the code image to obtain confidential information. Alternatively, the extracting section 65 restores the code image and obtains access information. A control section 7 accesses a management apparatus 8 based on the access information and requests confidential information related to the information medium. The management apparatus 8 transmits the specified confidential information to an image processing apparatus.

  • Publication number: 20080184946
    Abstract: A rocker cam is comprised of a first split body and a second split body, which are joined with a joint split face that contains an axial line of a cam shaft. The first split body has a first pin support portion that supports one end portion of the connection pin, and the second split body has a second pin support portion that is located so as to face the first pin support portion and supports the other end portion of the connection pin. The connection pin is supported at the first and second pin support portions at its both end portions. Accordingly, a separation force that acts on the first and second split bodies of the rocker cam during its repeated rocking movement can be reduced without improperly increasing its rigidity.

  • Patent number: 7320054
    Abstract: Disclosed is a multiprocessor system in which even if contention occurs when a common memory is accessed from each of a plurality of processors, the number of times the common memory is accessed is capable of being reduced. The common memory of the multiprocessor system is provided with a number of data areas that store data and with a control information area that stores control information indicating whether each of the data areas is in use, and each processor is provided with a storage unit equivalent to the common memory and with an access controller. The access controller of a processor that does not have access privilege monitors data and addresses that flow on the common bus, accepts data written to the common memory and data read from the common memory, and stores this data in the storage unit of its own processor, thereby storing content identical with that of the common memory.

  • Patent number: 6523510
    Abstract: A valve drive mechanism includes a tappet assembly which comprises a center tappet, a pair of side tappets between which the center tappet is interposed so as to move relatively to the side tappets, and a locking/unlocking mechanism operative to mechanically couple the center tappet to both of the side tappets and to uncouple the center tappet from both of the side tappets so as to selectively transmit rotation of a high lift center cam and low lift side cams to twin valves such as twin intake valves and twin exhaust valves per cylinder. Locking/unlocking of the center tappet and each side tappet is performed in a position which is in a vertical plane including a center axis of each side tappet and intersecting perpendicularly to an axial direction of a camshaft and is offset from the center axis of the side tappet.
