Abstract: A dog clutch control apparatus for an automated transmission includes a rotary shaft, plural dog clutch mechanisms, each of the dog clutch mechanisms including a clutch ring, a clutch hub arranged next to the clutch ring, a sleeve fitted with the clutch hub, a dog clutch portion which is provided at the clutch ring and selectively meshes with a spline formed at the sleeve, an axial driving device for moving the sleeve, the dog clutch control apparatus includes a disengagement detecting portion for detecting disengagement before the sleeve reaches a neutral position and a control apparatus for controlling operation of the axial driving device, wherein in a case where the disengagement is detected at a time of shifting operation, the control apparatus starts a shift-related control.

Abstract: An automatic shift device for an automated transmission for a vehicle includes a rotation shaft, a clutch ring, a clutch hub, a sleeve, a dog clutch portion, a shaft moving apparatus, and a control portion. The control portion includes a push force reduction control portion performing a push force reduction control reducing a push force of the sleeve that the shaft moving apparatus applies on the clutch rear teeth in response to a back and forth movement of the sleeve after the sleeve reaches an end surface of the clutch rear tooth. The control portion includes a retry control portion performing a retry control that re-applies the push force of the sleeve in response to a predetermined retry condition after the push force reduction control is performed.

Abstract: An automatic shift apparatus includes a rotation shaft, a dog clutch gear shift mechanism, and a control unit. The control unit controls first moving speed to be faster than second moving speed on moving a sleeve in an engaged state engaged with one of a first clutch ring and a second clutch ring to a neutral position defined at a position between the first clutch ring and the second clutch ring where the first moving speed is a speed of moving the sleeve in the engaged state to a target position defined between the neutral position and the mentioned one of the first clutch ring and the second clutch ring the sleeve is engaged with and where the second moving speed is a speed of moving the sleeve from the target position to the neutral position.

Abstract: An automatic shift apparatus including a rotation shaft, a dog clutch gear shift mechanism, and a control unit. The control unit supplies a predetermined electric current to a shaft moving apparatus to move a sleeve in an engaged state engaged with one of a first clutch ring and a second clutch ring and supplies a braking electric current smaller than the predetermined electric current to the shaft moving apparatus to exert a braking force on the sleeve, the braking force directed in the opposite direction relative to a direction of movement of the sleeve, before a spline of the sleeve disengages from a first dog clutch portion or a second dog clutch portion of the mentioned one of the first clutch ring and the second clutch ring.

Abstract: An apparatus which is operated for opening and maintaining the flow of a gaseous fuel to a burner only after the fuel is ignited in a gas appliance, such as a gas room heater. More specifically, the apparatus has a lever with three operating positions, a starting position, an intermediate position, and a final position. From the starting position, which is an inoperative mode, the lever is capable of being moved in a first direction to an intermediate position wherein actuation of a valve to the fuel source occurs allowing fuel to enter into the burner, and a final position wherein ignition of the fuel in the burner is actuated. A continuous force urging the lever in a second or opposite direction is included as well as a locking mechanism for holding the lever in the intermediate position, which locking mechanism is activated only after the lever has first been moved to the final position, hence avoiding the condition where the burner is continuing to be supplied with fuel without ignition of the fuel.

Abstract: An operation control apparatus, in a combustion device, comprising an operation member (4) selectively settable at a stop position (A), an ignition position (B) or an open position (C); an electric member (10) and/or (15) which is energized by an electric power source (20) when the operation member is set in its ignition position; and a limited time operation circuit for affecting the operation of the electric member (10 and/or 15), either by itself energizing the electric member or by enabling the electric member to be energized by the power source (20), for a predetermined period of time. In the apparatus disclosed, the limited time operation circuit is inoperative for affecting the operation of the electric member (10 and/or 15) while the operation member (4) is set in its ignition position (B) and the electric member is energized by the power source (20).
