| 20100077976 | Internal combustion engine with variable valve control system - An internal combustion engine is equipped with a variable valve control system which is operable to selectively actuate an engine valve using one of two cams of a camshaft, by sliding a rocker arm in the axial direction of a rocker-arm shaft. The system is capable of restricting the axial-direction movement of the rocker arm within a predetermined range, using a simple structure without unduly increasing the number of component parts. Position-restriction portions are formed in a rocker arm, and abut on a trigger arm to restrict sliding movement of the rocker arm within a predetermined amount, when the trigger arm is disengaged from the rocker arm. | 04-01-2010 |
| 20100077977 | Internal combustion engine equipped with a variable valve control system - The invention provides an internal combustion engine equipped with a variable valve control system which switches the actions of an engine valve by sliding a rocker arm in the axial direction of the rocker arm shaft, while enabling the restriction on the sliding movement of the rocker arm to be removed in accordance with the timings of the actions of the rocker arms irrespective of the engine speed. The internal combustion engine includes an actuator that moves a rocker arm shaft in its axial direction, a trigger arm that engages with a rocker arm to prohibit the sliding movement of the rocker arm, and a trigger pin which is configured to be activated by an axial movement of the rocker arm shaft to bring the trigger arm into action, and to disengage the trigger arm from the rocker arm. | 04-01-2010 |
| 20100077979 | Internal combustion engine having a variable valve control system, and method of using same - An internal combustion engine includes a variable valve control system which is operable to switch actions of an engine valve by slidably moving a rocker arm in the axial direction of a rocker-arm shaft, and which is capable of removing a restriction on the sliding movement of the rocker arm at accurate timings while employing a simplified configuration. When a trigger arm swings by a predetermined amount to the opposite side of a rocker arm, a left-hand engagement nail in engagement with an engagement groove disengages from the engagement groove, but a right-hand engagement nail still engages with an engagement groove. The left-hand engagement nail is placed on top of a left-hand deck-like portion. After that, when an action of the rocker arm makes the trigger arm further swing to the opposite side of the rocker arm, the right-hand engagement nail disengages from the engagement groove. | 04-01-2010 |
| 20100242874 | VARIABLE VALVE-ACTUATING MECHANISM FOR AN INTERNAL COMBUSTION ENGINE, AND ENGINE INCORPORATING SAME - In an internal combustion engine, a variable valve-actuating mechanism includes a trigger pin operable to permit axial movement of a rocker arm concurrently with a axial movement of a rocker arm shaft. A retention member has an insertion aperture formed therein, in which the trigger pin is inserted, and which slidably supports the trigger pin in the inserting direction. The trigger pin includes upper and lower expanded portions disposed on both sides thereof in the inserting direction. The upper and lower expanded portions of the trigger pin are operable to disable sliding motion of the trigger pin, relative to the retention member, beyond a predetermined range. The upper and lower expanded portions allow the trigger pin to be integrally assembled in the insertion aperture of the retention member, so as to be selectively retained therein. | 09-30-2010 |

| 20090255425 | SCREEN PRINTING APPARATUS AND SCREEN PRINTING METHOD - The invention provides a screen printing apparatus and a screen printing method with which the separability of the printing member just after printing a print material has been improved. This invention relates to a screen printing apparatus comprising: a printing means including, a printing member with elasticity and with soft magnetism, with opening corresponding to a pattern, with a print area to which a print material is supplied and in which said opening is included, with one face which is aligned with one face of said work in predetermined positional relation, and also including a supporter supporting said printing member, a feeding means supplying the print material while pushing the print area from another face of the printing member, formed so that the upper part of the printing member can move along one direction at least, and a magnetic force generating means pulling up the printing member synchronously with the feeding means, formed behind the feeding means to cover the print area along moving direction of the feeding means. The magnetic force generating means comprises two or more magnetic domains on one face facing the printing member, and magnetic poles of adjoining the magnetic domains are opposite to each other. | 10-15-2009 |
| 20100065020 | FUEL INJECTOR - To provide a fuel injector that has excellent durability with respect to pressure of high-pressure fuel and can accurately perform injection control even when injecting even higher pressure fuel. | 03-18-2010 |
| 20100108036 | COMMON RAIL AND METHOD OF MANUFACTURING COMMON RAIL - To provide a common rail that can prevent stress concentration from arising locally with respect to intersecting portions between a flow path and branching paths and can prevent damage such as cracks. | 05-06-2010 |
| 20110210483 | MOLTEN METAL SUPPLY CYLINDER, MOLTEN METAL SUPPLY APPARATUS INCORPORATING SUCH A SUPPLY CYLINDER AND MOLTEN METAL SUPPLY METHOD - An object of the present invention is to provide a molten metal supply cylinder that has a simple configuration if compared with the configurations of the prior art and can suppress mixing of oxide that is produced on the surface of a low melting point metallic material in a solid phase with molten metal. | 09-01-2011 |
