In method of manufacturing a light transmitting plastic member having a desired optical characteristic distribution from a gelled base material having a rotation axis, the base material is places in a monomer having an optical characteristics different from that of the base material, and is rotated around the rotation axis thereof in the monomer so that the monomer is diffused into the base material while the base material is rotated. The light transmitting plastic member is made from the base material.

A motor-driven vehicle capable of increasing the degree of freedom of wiring for a motor. A drive wheel having a motor with a stator and a rotor serving as a drive source disposed in a wheel hub is rotatably supported on a wheel shaft between right and left forks. The stator is provided in a body-side retainer member fixed to a vehicle body, the rotor is rotatably supported on the wheel shaft, and wiring for the motor is passed through the body-side retainer member. The brake mechanism is provided on the drive wheel. As seen from a front of a vehicle body, the wheel hub is rotatably supported on the wheel shaft on one lateral side alone from a body center and the brake mechanism is disposed on one lateral side from a body center and the motor is disposed on the other lateral side from the body center.

A saddle seat type fuel-cell electric vehicle includes a motor for driving rear wheels, a secondary battery for supplying electric power to the motor, a carrier for carrying luggage and a seat for supporting an operator, the carrier is located behind the seat and above the rear wheels. The secondary battery includes a plurality of cells each having an elongated boxlike shape, and it is stored in the internal space of the carrier, thereby increasing the flexibility of the layout of the vehicle body. Spacings functioning as air passages are defined between the inner wall of the carrier and the secondary battery. The carrier is formed with air inlet openings for introducing an air flow into the internal space and an air outlet opening for discharging the air flow out of the internal space. The plural cells are arranged adjacent to each other with given intervals on the same plane.

摘要:
A control apparatus of an electric vehicle for effectively limiting the operation of the vehicle when it is determined that a driver of the electric vehicle is not sitting in the seat and an accelerator opening of the electric vehicle is in a position corresponding to a minimum value. A motor driving enablement circuit generates a motor driving command which selectively limits operation of the electric vehicle in accordance with these determinations. In addition, when a state in which the driver is not occupying the seat continues for a period of time exceeding a predetermined value, a motor halt controller issues a motor halt command for halting a motor of the electric vehicle. Based on the motor driving enablement command and the motor halt command, a power supply controller controls the supply of power to the motor of the electric vehicle.

A regenerative braking control system consumes energy generated in a period corresponding to an angle .theta..sub.1 which starts in a half of a period of an AC voltage produced in a drive motor during the braking of the drive motor. The regenerative braking control system also consumes energy generated in a period corresponding to an angle .theta..sub.2 that ends at the end of a half of a period of the AC voltage. The regenerative rate of braking control system utilizes a current induced in the driving coils of the drive motor at the end of the period corresponding to the angle .theta..sub.1 to recharge a battery. By utilizing two periods to carry out the regenerative braking process, the recharging energy and the braking force can be controlled individually. Moreover, a controller monitors the electric control system to determine whether a malfunction is present. If a malfunction is detected, an electrical brake electrically brakes the drive motor. This electrical braking after the detection of a malfunction in the electrical system provides satisfactory controllability of the electric vehicle.

摘要:
This invention relates to a halide-containing stimulable phosphor having improved moisture resistance and luminance, and a process for producing the same. The halide-containing stimulable phosphor is characterized in that, among elements constituting the outermost surface and inside of the phosphor, there is a difference in composition ratio of a halogen element between the outermost surface and the inside of the phosphor. A radiation image conversion panel, which has been improved, for example, in moisture resistance, luminance and image quality by using the phosphor, and a process for producing the same are also provided.
