摘要： A laser scanning optical system converts a plurality of beams emitted from the laser diode (LD) into parallel light using a collimator lens, shapes the parallel light using an aperture, and executes exposure of a plurality of lines simultaneously on a photoreceptor drum. To cause a necessary emitting point interval d determined uniquely from the magnification of the optical system to coincide with an emitting point interval of the LD used, the LD is rotated by an angle θ against the main optical axis plane thereof. In this case, a converting device that converts the aspect ratio of a profile of the light beam emitted from the LD is provided. A conversion characteristic of the converting device is adjusted such that the characteristic is matched with a condition within a predetermined region following a characteristic of the optical system.

摘要： An image forming apparatus includes a charging roller for charging a surface of a photoconductive layer in a photoreceptor so as to have a prescribed polarity, a first exposing unit which is arranged on a downstream side of the charging roller on the basis of a direction in which the photoreceptor moves, a developer unit which is placed on a downstream side of the first exposing unit and which keeps toner, to which a charge with a polarity opposite to the prescribed polarity is applied, in contact with a photoconductive layer, and a second exposing unit for directing light generated according to an image signal to a back of the photoconductive layer at a contact position of the toner and the photoconductive layer. The first exposing unit directing light reflected from a document to which a light is applied to the surface of photoconductive layer so as to form a first electrostatic latent image. The second exposing unit forms a second electrostatic latent image by interlocking or synchronizing with the developing operation of the developer unit. This makes it possible to easily form a synthetic image at a high speed by superimposing characters printed by a printer function onto a copy image formed by a copying function, for example.

摘要： A straddle type vehicle includes a protrusion which is displaced together with a throttle valve, a lever pulley which is displaced in response to the rotation of a throttle grip, a spring and a control device. The spring generates elastic force to return the protrusion to a first original position when the lever pulley is in a second original position. The spring maintains the lever pulley in the second original position by being elastically deformed until the protrusion reaches a predetermined position in which the protrusion is displaced from the first original position in such a direction that the throttle valve opens when the lever pulley is in the second original position. The control device opens the throttle valve by displacing the protrusion until the protrusion reaches the predetermined position in a gear shift change when the throttle grip is fully closed.

摘要： An image forming apparatus in accordance with the present invention is provided with a unit composed of members such as a photoreceptor drum and an optical system, the unit being attachably and detachably provided with respect to the image forming apparatus main body. With the arrangement, the replacement of the photoreceptor drum can be made at the user's end with ease. It is not necessary to carry out fine adjustments at the user's end for positioning the photoreceptor drum and optical system with respect to the image forming apparatus main body. Thus, professional skill is not required for the replacement of the photoreceptor drum, thereby resulting in that the operations such as maintenance can be effectively made. It is preferable that a cleaner is further provided for removing any contaminated materials adhering to the inner surface of the photoreceptor drum. With the cleaner, the contaminated materials can be removed from the inner surface of the photoreceptor drum, thereby avoiding that the exposure of the photoreceptor drum is not appropriately carried out.

摘要： A motorcycle sets a target slip value based on an accelerator operation by a driver, and prevents a significant decrease in the output torque of the drive power source during execution of traction control to provide a comfortable ride. The motorcycle includes a target slip value calculating section that calculates a target slip value, based on an accelerator operation by a driver; and an actual slip value calculating section that calculates an actual slip value, based on the difference between the rotation speed of the front wheel and the rotation speed of the rear wheel. The motorcycle further includes a drive power source controller arranged and programmed to reduce the output torque of the drive power source, based on the difference between a criterion value different from the target slip value and the actual slip value when the actual slip value is lower than the target slip value.

摘要： In an image forming apparatus, flying of toner from a toner holder towards a counter electrode is controlled by giving a potential to a control grid according to an image signal. Here, a distance between the control grid and the toner holder is set so as to be shorter than a pitch of a gate. The toner passes through a plurality of gates which is a passing section of the toner in the control grid and adheres to a sheet so as to form an image on the sheet. Furthermore, in the image forming apparatus, image signals to be inputted serially from an image reading unit are distributed to odd lines and even lines so as to respectively stored into the odd memory and the even memory. The image signals are stored into the odd memory and at the same time the image signals stored in the even memory are read out.
