A partial groove 14 is formed in an inner circumferential surface of an upper side bearing member 11 of a main bearing 5 which pivotally supports a main shaft 3A of a crankshaft 3, and a space D between an end portion of the partial groove 14 and each of crush reliefs 11b formed at both ends in a circumferential direction of the upper side bearing member 11 is provided within a range of 2 mm≦D≦main shaft diameter/3. Further, a depth gradually decreasing portion 14b having an arc-shaped section is formed at an end portion of the partial groove 14, and a radius r of the depth gradually decreasing portion 14b is provided within a range of 0≦r≦main bearing inner circumferential surface radius×0.5. Further, in a connecting rod bearing 6, a lubricating oil discharge passage 23, which discharges a lubricating oil outside a connecting rod 4 when communicating with an internal passage 3C formed in the crankshaft 3, is provided.An amount of the lubricating oil which is discharged from a sliding portion of the main bearing is suppressed, and damage to the main bearing and the connecting rod bearing due to a foreign substance in the lubricating oil can be prevented as much as possible.

An integrated transmission apparatus includes a plurality of optical supervisory channel (OSC) processing units for processing OSC signals contained in a wavelength division multiplexing (WDM) signal received from a WDM network and a switching unit for performing the path control of synchronous digital hierarchy (SDH) frames. An OSC processing unit transmits the SDH frame, containing wavelength information indicated by, to the switching unit. Another OSC processing unit acquires the SDH frame, containing wavelength information, from the switching unit and sets an OSC signal which is to be appended to the WDM signal to be transmitted, based on the wavelength information.

A saddle-ride vehicle includes an engine with a front cylinder extended forward and diagonally upward from a crankcase. The engine is mounted between a front wheel and a rear wheel. A space gradually vertically extended forward is provided between a fuel tank arranged on the upside of the front cylinder and a front head cover provided to an upper part of the front cylinder. A radiator upstream water passage extended backward from an upper part of a radiator is provided in front of the front cylinder and is arranged in the space. The radiator upstream water passage is covered with a front overhead cover attached to the front cylinder. With this configuration, vehicle body components are not exposed, thereby protecting the vehicle body components. In addition, the appearance of the vehicle is efficiently enhanced.

A wire is provided in a turn signal power cord drawn out from a turn signal indicator fixed to a front fork while achieving a good appearance. A turn signal indicator includes a lamp case housing a lamp, and a stay member coupled to the lamp case. The stay member includes an annular collar fitted around a circumference of a front fork shaft. A cord-housing groove is formed in an outer part of the annular collar. A turn signal power cord is drawn out from the lamp case to the annular collar through an arm part to the outside through the groove. The cord-housing groove is covered with a cover, which is formed integrally with a locking member that engages with a slot part of a top bridge, as an anti-rotation component of the apparatus.

In a solid state imaging device to be included in an imaging device such as a digital camera, a ramp run-up AD conversion circuit for AD converting a pixel signal is provided corresponding to one or a plurality of pixel columns. A column counter provided in each ramp run-up AD conversion circuit holds an upper bit, and a clock signal is supplied to one or plural latches for holding a lower bit. Thus, fast and accurate AD conversion can be realized while suppressing increase of clock frequency.

An image forming apparatus is provided, which prevents occurrence of conveying malfunction or image failure due to variation of conveying speed caused by endurance of a fixing unit or a conveying unit, variation of using environment, or a type of a recording material. The image forming apparatus includes: a fixing unit for heating and fixing a toner image on a recording sheet (P); a secondary transferring portion for conveying the recording sheet (P) to the fixing unit; a loop sensor for detecting a degree of a loop of the recording sheet (P) generated according to a speed difference between a conveying speed of the fixing unit and a conveying speed of the secondary transferring portion; a CPU for controlling the conveying speed of the fixing unit; a fixing deliver sensor for detecting a used amount of the fixing unit; and an EEPROM for storing information on the used amount of the fixing unit detected by the fixing deliver sensor. The CPU controls the conveying speed of the fixing unit based on the information of the used amount of the fixing unit stored in the EEPROM and a detection result of the loop sensor.

The present invention provides an electron beam apparatus for irradiating a sample with primary electron beams to detect secondary electron beams generated from a surface of the sample by the irradiation for evaluating the sample surface. In the electron beam apparatus, an electron gun has a cathode for emitting primary electron beams. The cathode includes a plurality of emitters for emitting primary electron beams, arranged apart from one another on a circle centered at an optical axis of a primary electro-optical system. The plurality of emitters are arranged such that when the plurality of emitters are projected onto a straight line parallel with a direction in which the primary electron beams are scanned, resulting points on the straight line are spaced at equal intervals.

When a retard roller is rotating in a sheet feeding direction, the rotation is transmitted to a pickup roller and the pickup roller rotates in a direction for conveying the sheet. When the retard roller is rotating in a direction opposite to the sheet feeding direction or is stationary, the pickup roller does not feed the sheet. Therefore, in a successive feeding operation, the sheet to be fed next is always conveyed such that the leading end thereof reaches a nip position between a feed roller and the retard roller. Therefore, the intervals between the sheets are uniform in the successive feeding operation.

A measurement cell (40a) is formed so as to extend in a direction along which a centrifugal force is applied, and a capillary area (47a) to which a sample liquid is sucked by a capillary force is formed on one of the side walls of the measurement cell (40a), the side walls being arranged in a rotational direction. The capillary area (47a) extends from the outer periphery position to the inner periphery of the measurement cell (40a), thereby reducing the size of an analyzing device. Further, the sample liquid in the measurement cell (40a) is sucked to the capillary area (47a) by slowing or stopping a rotation, and then the rotation is accelerated to return the sample liquid in the capillary area (47a) to the measurement cell (40a). It is therefore possible to achieve a sufficient agitating effect and conduct measurement with a small quantity of sample liquid.
