A microscope for virtual-slide creating system has a stage for holding the specimen, a transmitted-light illumination optical system for illuminating the specimen with transmitted light, an objective, a tube lens and an image capture unit. The objective is configured as a dry system of infinity-corrected type with an object-side numerical aperture of 0.8 or greater and a focal length for d-line rays in a range from 8 to 20 mm. The tube lens has a focal length in a range from 160 to 280 mm. The image capture surface of the image capture unit has a long side of 12 mm or longer and a pixel size (μm) satisfying the following condition: a (μm)≦(0.61×0.59 (μ/m))/NA′ where a is the pixel size, and NA′ is an image-side numerical aperture.

A power unit provided with a dry sump type lubricating device includes a power unit case that is covered in part by a power unit case cover and is divided into a front unit case and a rear unit case. The power unit also includes a crankshaft rotatably supported by a crank chamber that is formed by the power unit case and a shift shaft rotatably supported by a transmission chamber that is provided adjacent to the crank chamber. The power unit also includes an oil tank disposed on the crank chamber side of an anteroposterior outside surface of the power unit case cover and a hydraulic control device for controlling a shift clutch, disposed on the transmission chamber side of the anteroposterior outside surface of the power unit case cover.

To achieve downsizing of a power unit and the vicinity thereof by permitting compact axial arrangement in a straddle-ride type vehicle on which the power unit having a twin-clutch type transmission is mounted. The transmission has a pair of main shafts with respective different axes and corresponding clutches. One of respective axial centers of the main shafts is disposed on one (above) of the sides with respect to a line and the other is disposed on the other side (below), the line connecting an axial center of the counter shaft with an axial center of a pivot shaft, as viewed in side elevation from the axial direction of the main shafts and counter shaft.

A saddle type vehicle having mounted thereon a power unit is provided with a twin clutch type transmission including a pair of main shafts and a pair of clutches along different axes, to enable a compact layout of axes and a reduction in size of the unit and its surroundings. The axis center (first main axis) of a first main shaft is disposed rearwardly of the axis center (crank axis) of a crankshaft and forwardly of the axis center (counter axis) of a counter shaft, whereas the axis center (second main axis) of a second main shaft is disposed rearwardly of the axis center (counter axis) of the counter shaft and forwardly of the axis center (pivot axis) of a pivot shaft.
摘要:
In a vehicle power unit including a twin clutch type transmission that includes a pair of main shafts and clutches mounted on mutually different shafts, to enable compact shaft arrangements and to achieve a reduction in the size of the unit and the surrounding areas. Axial centers of a shift drum and a countershaft are disposed across a line that connects axial centers of main shafts in a side view as viewed from a direction of an axis of each of the main shafts and the countershaft.

There is provided a saddle-riding type small vehicle where a power unit is mounted on a vehicle body frame. The power unit includes a valve control device that controls the operation of valve-operation mode changing mechanisms capable of changing operation modes of engine valves, and a clutch control device that controls the operation of a clutch unit provided between a crankshaft and a shift mechanism so as to shift the connection/disconnection of power transmission. In the vehicle, the valve control device and the clutch control device are disposed to balance the center of gravity, so as to make a power unit compact. A valve control device and a clutch control device are disposed on left and right sides of a center line CB of a vehicle in a width direction of the vehicle.

In a motorcycle-use power unit in which a clutch device arranged in a power transmission path between a crankshaft and a drive wheel is housed in a clutch chamber which is defined between a crankcase and a clutch cover joined to a side surface of the crankcase, the maintenance of the clutch control device can be easily performed while preventing a lowering of oil-pressure transmission efficiency between the clutch device and the clutch control device and preventing an increase in the weight of the motorcycle. A clutch control device performs a changeover of engagement and disengagement of a clutch device by controlling the oil pressure applied to the clutch device. Oil passages for connecting the clutch control device and the clutch device with each other are mounted on a clutch cover.

A lubricating oil passage 113 includes an upstream oil passage 113a defined coaxially in a rotational shaft 71 for supplying lubricating oil to lubricated parts and a downstream oil passage 113b connected to the upstream oil passage 113a for supplying lubricating oil to canceler chambers 97, 107. The downstream oil passage 113b may be smaller in diameter than the upstream oil passage 113a and having at least a portion extending parallel to the axis of the rotational shaft 71. Control oil passages 111, 112 which have axes parallel to the axis of the rotational shaft 71 are defined in the rotational shaft 71 such that at least a portion of the control oil passages 111, 112 is disposed in a range wherein the downstream oil passage 113b is provided in a direction along the axis of the rotational shaft 71.
