A swing arm support structure is provided in a motorcycle, in which first and second support arm portions are provided on a front portion of a swing arm. The support arm portions are pivotally supported by a power unit through first and second pivot shafts, so that rigidity and strength of the paired support arm portions is ensured. A flange is formed on the first pivot shaft, which extends at least partially up to an outer edge of a power unit case and projects radially outwardly from an end portion of the first pivot shaft adjacent the case. The flange portion is removably attached to the case. An outer end of an output shaft extends through and is supported by the first pivot shaft, and this outer end projects outwards of the first support arm portion. A drive gear is fixed to the outer end portion of the output shaft.

The present invention provides a vacuum system including a vacuum pump capable of operating at a rotation rate controlled appropriately when a predetermined process is performed in a vacuum chamber, which contributes to energy conservation. The vacuum system serves as a semiconductor manufacturing system comprising a vacuum pump controller which has a gas flow mode and an auto-tuning mode for determining a rotation rate of a vacuum pump unit to set the rotation rate to a target value lower by a predetermined value than the full operation rate of gas flow rate control means under the condition that pressure within the process chamber is vacuum pressure necessary for the gas flow mode. The vacuum pump controller has means for reducing the rotation rate of the vacuum pump unit from a rated rotation rate in the auto-tuning mode under the condition that pressure within the process chamber is vacuum necessary for the gas flow mode, to determine whether or not the operation rate of an APC valve reaches a target value, and means for storing, as the rotation rate necessary for the gas flow mode, the rotation rate of the vacuum pump unit, which is obtained when it is determined that the operation rate of the APC valve reaches the target value.

The invention provides a low temperature probe having a high sensitivity by reducing a heat intrusion into a receive coil. A heat making an intrusion into a coil is suppressed by inserting a heat radiation shield in which a temperature is controlled at about 100 K to a portion between an outer container of a probe and a coil portion. A heat radiation shield bore sleeve is provided in a heat radiation bore, is connected to the heat radiation shield, and is cooled by a second heat exchanger. Further, the coil portion is cooled by a first heat exchanger. In preparation for a contraction at a time of being cooled, the outer container, the heat radiation shield and the coil portion are connected by using a fixing portion, and a heat relieving mechanism or a contraction relieving mechanism is provided in a root side (an opposite side to the fixing portion) of the heat radiation shield and the coil portion. The fixing portion is formed in a shape and made of a material having a small heat intrusion amount and having a small heat contraction.
