A battery is disposed close to a through-hole of a swing shaft that pivotally supports a swing arm on a vehicle body frame so as to be freely swingable at a position closer to the front of the vehicle body in the swing arm. An electric motor is disposed close to an axle of a rear wheel at a position closer to the rear of the vehicle body in the swing arm. The control board is disposed at a position outside of the battery in the vehicle width direction, and the heating element board is disposed at a position rearward of the vehicle body with respect to the control board and forward of the vehicle body with respect to the motor.

The present invention provides a surface treatment method for a water-absorbing resin comprising three steps of: 1) a humidifying and mixing step for mixing a base polymer and a surface cross-linking agent solution to obtain a “humidified substance”; 2) a pretreatment step for raising temperature of said humidified substance to obtain a “pretreated substance”; and 3) a surface cross-linking reaction step for cross-linking said pretreated substance to obtain a surface cross-linked “water-absorbing resin”; wherein dew point in the pretreatment step of the above 2) is from 50° C. to 95° C., and temperature of said humidified substance is raised from temperature below the dew point up to a temperature of 10° C. higher than the dew point.

To prevent semiconductor chips from adhering to the trays during transport, a method is employed which transports semiconductor chips in the following state. When trays provided with a plurality of accommodating portions having a recessed cross section for accommodating semiconductor chips on a main surface thereof are stacked in a plurality of stages, the semiconductor chips are accommodated in spaces defined by the accommodating portions formed over the main surface of the lower-stage tray and corresponding accommodating portions formed over the back surface of the upper-stage tray. Here, on bottom surfaces of the accommodating portions formed over the back surface of the upper-stage tray, isolated projections having a height which prevents the projections from coming into contact with the semiconductor chips are arranged in a scattered manner. In this way, it is possible to prevent the semiconductor chips from adhering to the back surface of the upper-stage tray.

A navigation system is mounted in a vehicle positioned in a facility, whose on-site passage data is unavailable for the system. In this case, the system determines whether a facility exit is learned. When the facility exit is learned, the system defines, as a facility exit coordinates, the learned coordinates. When the facility exit is not learned, the system defines, as the facility coordinates, a guidance coordinates, which is used to terminate a route guidance when the facility is designated as a destination. The system then retrieves a route using the defined facility exit coordinates as a departure position. Even when the on-site passage data is unavailable, defining the facility exit allows the system to highly accurately retrieve a route passing through the actual facility exit.
