A steering handlebar apparatus for a vehicle includes a rod-shaped steering handlebar having a hand grip at a distal end thereof, and also includes both a clutch lever and a hot start lever mounted thereon at a position proximal to the hand grip. A switch holder for holding various switches is mounted to the steering handlebar at a position proximal to the hand grip. The hot start lever is journaled on the lower surface of the switch holder so that the user can operate the hot start lever with the thumb of the hand which is holding the hand grip, and can simultaneously turn off the clutch lever with other fingers of the same hand. The inventive arrangement provides a steering handlebar apparatus for a vehicle which facilitates simultaneous operation of a handle lever and a hot start lever using the hand which is holding a hand grip of a steering handlebar.

An image forming apparatus includes an image bearing member for carrying an electrostatic image, a contact charger for electrically charging the image bearing member while contacting to a surface of the image bearing member, the contact charger forming an oscillating electric field having a frequency of 100-600 Hz; a developer for developing the electrostatic image on the image bearing member with a developer comprising toner and a carrier having a volume resistivity value of 106-1010 &OHgr;.cm, while contacting chains of the carrier to the image bearing member, the developer including a developer carrying member, opposed to the image bearing member, for carrying the developer and electric field forming device for forming an alternating electric filed between the image bearing member and the developer carrying member; wherein the following relationship are satisfied: 5×10−5
摘要:
A motor control device for an electric vehicle is capable of protecting component units from damage and also protecting a storage battery from deterioration or breakage by preventing an excessive increase in a regenerative braking amount of a motor. An auxiliary controller controls the regenerative braking amount of the motor so that the voltage of the storage battery, which is detected by a voltage detector, stays at a predetermined voltage value or less at the time of regenerative braking of the motor.
摘要:
An image forming apparatus has an image forming device for forming an image on a recording material in response to an image on a document. The apparatus also has a glossiness detection device for detecting from the document the level of glossiness of the document image. The image forming device is controlled based on an output from the glossiness detection device. With this construction, the level of glossiness in response to the document image can be reproduced on the recording material, thus improving the quality of reproduced images.
摘要:
This invention has as its object to provide an image processing apparatus and method, which can obtain high image quality by adjusting an image forming parameter or parameters in consideration of a variation in image forming condition. In order to achieve the object, the gradation characteristics of an image to be recorded are adjusted on the basis of information obtained by forming a gradation characteristic adjustment test pattern on a recording medium, and reading the formed test pattern. Subsequently, the color reproduction characteristics of an image to be recorded are adjusted on the basis of information obtained by forming a color reproduction characteristic adjustment test pattern on a recording medium, and reading the formed test pattern.
