A clutch mechanism is provided between a drive wheel and an electric motor. In a high vehicle speed region, the electric motor is decoupled from the drive wheel to prevent the electric motor from over-speeding. In the high vehicle speed region, in which the clutch mechanism is switched to a disengaged condition, rotation speed control is executed on the electric motor when a state of charge falls below a predetermined lower limit value, and a motor rotation speed is maintained at a target rotation speed on a lower rotation side than an upper limit rotation speed. Further, the clutch mechanism is switched from the disengaged condition to a slip condition. Hence, a limited power generation torque is supplied to the electric motor, and thus the electric motor can be controlled to a regeneration condition while suppressing the motor rotation speed to or below the upper limit rotation speed.

Provided herein is a light-emitting apparatus which is capable of causing the light emitted at the entire face of a fluorescent material to be exteriorly emitted with no interference and with enhanced light emission efficiency, thereby attaining an exteriorly radiated high brightness light. A cathode electrode 10 is mounted on a periphery of a transmission member 30, the anode electrode 15 is also mounted on a domain opposite to a light transmission member 30, and the surface 16a of the fluorescent material 16 to be mounted on a top layer of the anode electrode 15 is formed with a concave face. In accordance therewith, even when the cathode electrode 10 is offset mounted on a periphery of the light transmission member 30 it can be caused to precisely face the surface 16a of the fluorescent material 16 and the excitation light from the entire face of the surface 16a of the fluorescent material 16 can made incident onto the light transmission member 30 without interference from the cathode electrode 10 or the like.
摘要:
An electron emitting source 6 is covered with a cathode mask 20 whose opening areas are substantially the same as those in a grid electrode 10, so that the areas for which the electrons are emitted from the electron emitting source 6 can substantially be the same as the opening areas in the grid electrode 10. Thus, substantially all the electrons emitted from these areas can be ensured to pass through opening portions 11 in the grid electrode 10 so as to be effective electrons that can contribute to light emission. In this way, power loss at the grid electrode 10 can be reduced. At the same time, harmful metallic sputtering caused at the grid electrode 10 toward a cathode electrode 5 can be reliably prevented, whereby damages on the cathode electrode can be avoided.

Provided herein is a light-emitting apparatus capable of achieving both improved durability and higher brightness with an inexpensive and simple construction. A heat resistant glass substrate 51 is mounted in a vacuum chamber 5, and while an anode electrode 8 (and a light emitter 20) is mounted on the glass substrate, the glass substrate 51 is separated from a glass substrate 11. This precisely protects the vacuum chamber 5 from thermal damage due to light emission upon excitation, even when the current density between the cathode electrode 6 and the anode electrode 8 is controlled at a high level to cause the light emitter 20 to emit light at high brightness. Accordingly, this eliminates the need to make the entire vacuum chamber 5 excessively heat-resistant, permitting construction from an inexpensive material such as soda-lime glass; consequently both improvements in the durability of the light-emitting apparatus 1 and enhancement in brightness thereof can be accomplished with an inexpensive and easy construction.

When impedance calculating conditions are satisfied after a system is started, the impedance of a battery is calculated using the current of the battery, a time variation in open circuit voltage thereof, a time variation in terminal voltage thereof, a time variation in current thereof, and a time variation in impedance thereof. The ratio of the calculated impedance to the initial impedance is calculated. The impedance ratio is subjected to weighting and averaging, thus obtaining a weighted average. When the system is terminated, an impedance-correction-coefficient learned value is updated using the weighted average. Thus, a change in impedance of the battery can be accurately grasped. Advantageously, parameters indicating the state of the battery, e.g., the remaining capacity thereof, reflect the change in impedance, resulting in accurate battery management.

Convergence angle information and image information of video cameras is transmitted from a multi-eye image-taking apparatus having two video cameras through a recording medium to a displaying apparatus. A convergence angle of display units in the displaying apparatus is controlled in accordance with the convergence angle information of the video cameras, permitting an observer to observe natural images. Since the convergence angle information is made ahead of the image information, the convergence angle of the display units can be changed with a natural feeling.

It calculates a capacity difference ESOC between a reference remaining capacity SOCV based on an open-circuit voltage and a final remaining capacity SOC in a previous one calculation cycle. It calculates a proportional correction amount and an integral correction amount according to a proportional-integral control by using this capacity difference ESOC, and requires a final remaining capacity SOC by adding a remaining capacity SOCI based on a current integration to these correction amounts. Thus, while making good use of the remaining capacity based on the battery open-circuit voltage, it can avoid the influence of the load fluctuation and require a remaining capacity always stable and accurate.
