  • Patent number: 8800400
    Abstract: A dog-clutch transmission system having dog-clutches is provided that can effectively lower the sound resulting from the engagement of dogs during the meshing of gears. A dog-clutch transmission system includes first gears installed adjacent to each other on respective shafts so as not to be rotatable relatively to the respective shafts and to be axially slidable; and second gears installed so as to be rotatable relatively to the respective shafts and not to be axially slidable. Each of the first gears has dog-teeth projecting in the axial direction and each of the other gears has dog-holes recessed in the axial direction. Speed-stages are switchable by bringing the dog-teeth and the dog-holes into engagement and disengagement. A speed-change ratio proportion of a change-speed ratio at an arbitrary n-speed speed-stage to a speed-change ratio at a (n+1)-speed speed-stage is set at 0.725 or more.

  • Patent number: 8727256
    Abstract: In case one of three clutch pawls protrudes outwardly from the side surface of a pawl base and engages with a clutch gear and the remaining two clutch pawls are not yet engaged with the clutch gear, the peripheral portion of a deforming through hole of the clutch pawl engaging with the clutch gear is plastically deformed and the clutch pawl is deformed in a substantially L-shape while engaging with the clutch gear. Then, the pawl base can be rotated further and the remaining two clutch pawls further protrude outwardly from the side surface of the pawl base and engage with the clutch gear.

  • Patent number: 8636126
    Abstract: A hydraulic clutch for preventing a drag of a clutch at the time of disengaging the clutch by decreasing an oil supply quantity between a plurality of clutch plates and a plurality of clutch discs thus decreasing a change hitting sound at the time of shifting. A hydraulic clutch is configured such that the superposition between an oil supply hole formed in a clutch pressure plate and an oil supply hole formed in a clutch center becomes maximum when the clutch is engaged.

  • Patent number: 8596567
    Abstract: In case a gas generating member of a pretensioner mechanism activates due to vehicle collision, a piston in a piston housing portion moves upwards from its normal position within a pipe cylinder. As a result, the piston comes in contact with a pinion gear portion and causes the pinion gear body to rotate abruptly. Further, a bottom end of a boss portion constituting one end portion of the pinion gear body is rotatably supported at a through hole of a base plate. Further, a support portion constituting the other end portion of the pinion gear body is rotatably supported at a support hole of a cover plate.

  • Patent number: 8555740
    Abstract: A transmission for an internal combustion engine that allows a fit length between a dog and a dog hole to be made longer and gear splines to be made longer, without having to increase an axial length of the transmission. A transmission selectively performs gearshifting by using a shift fork to slidingly move a shift gear of the transmission axially and by using a dog clutch to engage the shift gear with, or disengage the shift gear from, an adjacent gear. When the shift gear slidingly moves, a gear-side spline portion of the shift gear slidingly moves over a shaft-side spline portion.

  • Patent number: 8540178
    Abstract: When a pinion gear body (33) rotates co-axially with rotational axis of the take-up drum (6), a first rotation body (76) which is fixed to the pinion gear body co-axially rotates relatively to a second rotation body (77) which is mounted to the pinion gear body co-axially, as well, and does not rotate during initial rotation of the pinion gear body. Thereby, an engagement member (29) which is rotatably supported by the first rotation body and fitted to the first and second rotation bodies protrudes radially and outwardly. The engagement member that has thus projected gets engaged with the take-up drum. In this stage, the engagement member is pressed and moved by a guiding portion of the second rotation body in response to the relative rotation so as to be guided in an outward radial direction.

  • Patent number: 8463513
    Abstract: A transmission control apparatus for an automatic transmission to change a shift position automatically includes a cornering-state judging device, a modified shift-up table generator, and a gear-shift controller. The cornering-state judging device is configured to judge whether a vehicle has transitioned to a cornering state from a normal running state. The modified shift-up table generator is configured to generate a modified shift-up table when the vehicle is judged to have transitioned to the cornering state. The modified shift-up table makes a shift-up more difficult to occur than a reference shift-up table does. The gear-shift controller is configured to perform gear-shift control by using the reference shift-up table during the normal running state. The gear-shift controller is configured to suppress a gear shift by using the modified shift-up table instead of the reference shift-up table when the vehicle is judged to have transitioned to the cornering state.

  • Patent number: 8403365
    Abstract: A mounting concave portion with a predetermined depth is formed on a gas-pressure-receiving-side surface of a piston. Further, a plate-like sealing member includes a mounting convex portion which is erected at a position meeting with the mounting concave portion on the gas-pressure-receiving-side surface of the piston. When the piston and the sealing plate are assembled together, the mounting convex portion is fitted in the mounting concave portion. By merely pushing the mounting convex portion in the mounting concave portion, the sealing plate and the piston can be integrated, which improves productivity in assembly. Further, the sealing plate will not get twisted, deviated or displaced due to friction against inner wall of the pipe cylinder when the sealing plate and the piston are integrally inserted in the pipe cylinder. Deterioration of sealing function due to improper mounting of the sealing plate can be avoided.

  • Patent number: 8295268
    Abstract: An IP device (for example, network cameras 3a, 3b, and 3c) connectable to a router (for example, a router 2) makes a request to the router for assignment of a port number when a predetermined operation is performed, and notifies a management server 6 connected to a wide area network of address data containing an assigned port number when the port number is assigned from the router, wherein address data containing the port number can be registered in the management server 6 on the wide area network, so that, even when access is made from the terminal 4 on the wide area network side with a port number that is locally updated, access is made possible by transmitting address data of the IP device to the terminal 4.

  • Patent number: 8121878
    Abstract: The present invention calculates a predicted accumulative import amount for each chemical substance for each month by using information on a predicted monthly shipping amount and the amount of a chemical substance contained in the product and specifies the chemical substance whose predicted accumulative import amount exceeds a regulation threshold and the time when the import amount exceeds the regulation threshold. The present invention specifies the product containing the chemical substance, calculates the predicted shipping amount of the product from the threshold excess time of the chemical substance to the end of the year, and calculates the loss amount caused by the loss of sales opportunities from the profit per unit sales amount for each product when any regulation measures are not executed on the chemical substance. The present invention finally calculates the ratio of the expense necessary for the measures and the summed value, and displays the ratio.
