Abstract: An outboard motor adapted to be mounted on a stern of a boat and having a propeller to propel the boat, a power source which produces rotational output, a drive unit including a vertical shaft which transmits the rotational output of the power source to the propeller through a gear mechanism, and an interlock unit which detachably interlocks the power source to the drive unit. The changeable power source includes one of an internal combustion engine, an electric motor and a combination of the engine and the motor. The interlock unit interlocks one of the engine, the motor and the combination of the engine and the motor to the drive unit as the power source for propelling the boat, thereby enabling to freely change its power source as desired in accordance with a user's current needs and purposes.

Abstract: An outboard motor is provided with a bar handle equipped with a throttle grip enabling push-pull operation and rotate operation by the boat operator, and one or the other of the engine and the motor is connected to the propeller in accordance with the push-pull operation of the throttle grip. Owing to this configuration, switching between the power sources can be performed using the throttle grip of the bar handle. In addition, the engine speed and motor speed are regulated in accordance with the rotating operation of the throttle grip, thereby avoiding degradation of operability and increase in outboard motor size.

Abstract: The optical apparatus of the present invention comprises: a body; a lens barrel provided in the body; a camera shake compensation mechanism that swings the lens barrel about two different rotation axes; and a connection portion for connecting the body and the lens barrel which connection portion is partly fixed to the lens barrel and disposed along the point of intersection of the two rotation axes of the lens barrel or an area formed in the vicinity thereof. By this, the amount of flection of the connection portion can be reduced so that the space for absorbing the flection can be extremely small, and further, the stress imposed on the connection portion can be made extremely small. Consequently, an optical apparatus having a small-size and highly reliable camera shake compensation mechanism is obtained.

Abstract: The present invention provides an image capturing apparatus capable of easily finding an unsatisfactory point peculiar to a group picture at the time of taking a group picture and capable of taking a group picture with which all of subjects to be photographed are satisfied.

Abstract: A digital camera has an operation portion including at least one main operation member and provided on the back surface of a camera body, and a slide portion including a main display device and provided on the back surface of the camera body. The slide portion is sidable between a housed position that covers the operation portion and an image capturing position that exposes the operation portion on the camera body.

Abstract: The present invention relates to a programmable-gate-array copy protection method and a system which prevent unauthorized copying of an FPGA program. A copy protection method for a field-programmable gate array, the method comprising a step of causing a user-specific gate array to boot a user circuit data to the field-programmable gate array, the user-specific gate array being connected to the field-programmable gate array and a memory device in which the user circuit data is stored and being pre-programmed at a semiconductor-vender's factory.

Abstract: A camera has a lens barrier which can move between a closed position where a taking lens is covered and an opened position where the taking lens is exposed, and the on/off state of a power source is switched interlockingly with the open/close state of the lens barrier. A housing for housing the camera has a barrier driving lever for driving the lens barrier. At the time of attaching the housing, the tip of the barrier driving lever is retained by a finger retaining part of the camera to move the lens barrier to the opened position. As a result, attachment of the housing in a power-off state made by the lens barrier can be prevented.

Abstract: The present invention provides an image capturing apparatus capable of efficiently transmitting image data to an external device and having improved reliability in data transmission. A data communication mode established between a data communication part and an external device is determined by a communication mode determining part. A compression ratio setting part sets a compression ratio adapted to the data communication mode determined by the communication mode determining part and sets the compression ratio to a compressor. The compressor performs a compressing process on image data to be transmitted on the basis of the set compression ratio. The compressed image data is sent to the data communication part and transmitted to the external device.

Abstract: A digital camera capable of optimizing the circuit board disposition in a relationship with other parts when an optical system having refracting means for refracting the subject light is adopted, comprising: a body having a shape being flat in a subject direction when photographing; a refracting optical system having refracting means for refracting incident light from a subject in a direction vertical to the subject direction of the body; a power source portion supplying power to the image forming apparatus; and a circuit board disposed so as not to overlap with the refracting optical system and the power source portion in a direction of a thickness in the subject direction of the body.

Abstract: An engine includes an engine block having a crankcase, which has a first bearing on one sidewall and an opening on the other sidewall to assemble a crankshaft. A case cover is coupled to the crankcase by a plurality of bolts to close the opening, and which has a second bearing. Two knock pins are fit into the crankcase and the case cover over their joint faces at locations closer to a cylinder bore in the engine block than the second bearing. The knock pins define the position for coupling the crankcase and the case cover to each other and contribute to an increase in rigidity of the case cover. The supporting strength for the crankshaft is increased and the weight of the case cover is reduced.

Abstract: A library apparatus having a rotatable cell drum adapted to store a plurality of recording media cartridges, the cell drum having a plurality of columns and each column having plural cells configured to receive the recording media cartridges. The library apparatus further includes a door configured to selectively provide direct operator access to all of the cells of a selected column without the assistance of a media transport device. The library apparatus is provided with a cell drum locking mechanism configured to selectively lock the cell drum and prevent rotational movement of the cell drum, and a door locking mechanism configured to selectively lock the door and prevent opening of the door. A link operably interconnects the drum locking mechanism and the door locking mechanism such that the cell drum locking mechanism must assume a locked state before the door locking mechanism may assume an unlocked state.

Abstract: A library apparatus for storage media such as optical disks includes a rotatable cell drum having several columns of cells for storing the storage media, a load/unload device for inserting and removing cartridges one at a time, at least one drive for reading from or writing to selected media, and an accessor which moves the storage media between the load/unload device and the cell drum, and between the cell drum and the drive. The load/unload device rotates in a collinear arrangement with the cell drum, and can rotate in unison with the cell drum, or independently of the cell drum. The collinear arrangement of the cell drum and the load/unload device reduces the overall size of the library.
