Abstract: The toner contains binder resin-containing toner particles and silica fine particle S1, wherein the weight-average particle diameter of the toner is 4.0-15.0 ?m, both inclusive, peaks originating with the silica fine particle S1 are observed in 29 Si-NMR measurement of the silica fine particle S1, and, in the spectrum obtained by 29Si CP/MAS NMR or 29Si DD/MAS NMR, the peak area of a peak corresponding to the D1 unit structure in the silica fine particle S1, the peak area of a peak corresponding to the D2 unit structure in the silica fine particle S1, and the peak area of a peak corresponding to the Q unit structure in the silica fine particle S1 satisfy a prescribed relationship.

Abstract: To restrain an increase in the numbers of components and process steps and achieve an easy mounting and dismounting of a pivot shaft. An arm supporting member includes a pair of left and right plate members, a middle cross pipe extending between the plate members and a center pivot plate mounted to the middle cross pipe. A pivot shaft is supported by the plate member and the center pivot plate, and a drive shaft is arranged between the plate member and the center pivot plate. The middle cross pipe is arranged above the pivot shaft on a front portion of a vehicle. The center pivot plate is provided with an upright wall as a receiving portion for aiding the positioning of the bearing member by receiving the bearing member, more specifically, the collar when assembling the swing arm to the center pivot plate and the plate member.

Abstract: A fuel pump mounting arrangement for a motorcycle is provided in which the fuel pump is mounted to the vehicle body frame and in which the fuel pump is protected from impact without increasing the weight of a pivot plate. In the motorcycle, a main frame extends rearwardly from a head pipe, rear frames extend rearwardly from the main frame, and a central frame structure extends downwardly from the rear frames to form a space within the central frame structure. A pivot plate is mounted on a lower portion of the central frame structure, and a rear swing arm is supported on the pivot plate. In such a constitution, a fuel pump is arranged in the space which is formed by the central frame structure.

Abstract: A shroud is disposed outside a radiator. Ribs are provided which project from the inner surface of the shroud and abut the outer surface of the radiator so that portions other than the ribs are used as baffle passages for introducing running an air flow into air flow ports. Guide ribs for introducing an air flow in the air flow ports are provided which project from an inner surface of the shroud in front of the radiator, thereby enhancing the rectifying effect.

Abstract: To provide a motorcycle including a cooler disposed in such a manner so as to arcuately cover the front surface and the right and left side surfaces of a head pipe, wherein conduits connected to the cooler are disposed so as to prevent the need to reduce the capacity of a fuel tank and to prevent a thermal effect caused by the heated coolant. A cooler is provided on a head pipe positioned in front of a fuel tank. A first conduit for supplying coolant from the right side surface of an engine is connected to the upper surface of the right end of the cooler. A second conduit connected to the upper surface of the left end of the cooler passes along the upper surface of the cooler so as not to interfere with the fuel tank, and is connected to the right side surface of a tank. Wires and wiring cords extending from the steering handle extend along the left side surface of the head pipe to avoid the thermal effect of coolant at a high temperature.

Abstract: The present invention relates to a drive control circuit for controlling a driving system including, e.g., a carriage driving motor, a print head and others, which is to be employed in an apparatus such as a printer. More specifically, the present invention is concerned with a drive control circuit which can protect the driving system properly and prevent the driving system from being damaged, when a malfunction occurs in a ROM as in the case where the ROM in which a control program for controlling the driving system and a runaway detection program for the prevention of burning or the like which occurs in a driving motor as a result of the runaway of the control program have been written therein, is damaged or as in the case where no ROM is incorporated.
