Transfer paper for outputting color images, suitable for use as a transfer member used in a color electrophotographic apparatus capable of forming a multi-color toner image by using at least two colors of single-color toner. The paper has a whiteness degree of 85% or more and an opaqueness degree of 90% or more. A method of forming a color image includes the steps of transferring a color toner image to transfer paper having a whiteness degree of 85% or more and an opaqueness degree of 90% or more, and heatingly fixing the color toner image.

A tracheal airway apparatus includes an insert tube and an endoscope. The endoscope includes a body and an insert portion extending forwardly of the body and inserted into the insert tube. The insert portion is of a double tubular structure. An inner tube of the insert portion is flexible and receives an illumination light transmission element and an image transmission element. An outer tube of the insert portion has a semi-hard property and is detachably attached to a front end part of the body. A space is formed between an inner periphery of the outer tube and an outer periphery of the inner tube.

An image forming apparatus comprises a photoconductor on which a toner image is formed, an intermediate transfer drum disposed opposite to the photoconductor for holding a sheet on its circumferential surface, and a transfer charger disposed opposite to the photoconductor through the intermediate transfer drum for transferring a toner image from the photoconductor onto a sheet held on the intermediate transfer drum. A separation charger is disposed at a downstream side of the transfer charger in the rotational direction of the intermediate transfer drum for separating the sheet from the intermediate transfer drum, the output of the separation charger being set corresponding to the number of times the toner image is transferred.

A controller apparatus for an electric vehicle includes a power supply, a power converting section for converting power supplied from the power supply, a motor which receives an output from the power converting section to drive the electric vehicle; an accelerator opening detector for detecting an accelerator opening; a controller section for controlling said power converting section in response to a detected output from said accelerator opening detector; a current detector for detecting the current supplied to the motor from the power supply; and failure decider for deciding that the controller suffers a failure when the output from the current detector is not smaller than the reference value previously determined in accordance with the accelerator opening, thereby stopping the drive of the motor. In such a structure, the torque not smaller than that required by a driver is produced so that it is possible to prevent the electric vehicle from running away.

A torque transmission device of a four-wheel drive vehicle having a pair of drive shafts includes a hydraulic pump for transmitting torque to both drive shafts through a variable oil pressure generated therein according to the difference in rotational speed between both drive shafts, and a multiple disc clutch for transmitting torque to both drive shafts by a frictional coupling power. The hydraulic pump has a casing and a rotor housed therein. The casing is rotated by one of the drive shafts. The rotor is rotated by the other drive shaft through a transmitting member, a hydraulic piston mechanism and a rotary sleeve. The transmitting member has a clutch operating portion for operating the clutch. When the transmitted torque exceeds a predetermined level, the hydraulic piston mechanism is adapted to move the transmitting member to operate the multiple disc clutch with no intermediary of the casing.

A protective tube covering an insertion portion of an endoscope is shorter than an inner structure of the insertion portion, and a protective tube covering a bending portion is longer than an inner structure of the bending portion. The front end of the protective tube of the insertion portion, as well as the rear end of the protective tube of the bending portion, is disposed a predetermined distance rearwardly from a portion of connection between the inner structure of the insertion portion and the inner structure of the bending portion. The protective tube of the bending portion covers not only the inner structure of the bending portion but also the above connection portion and the front end portion of the inner structure of the insertion portion. Since the protective tube of the bending portion is softer than the protective tube of the insertion portion, the front end portion of the insertion portion covered by the former protective tube is more flexible and bendable than the other portion of the insertion portion, and serves as an insertion guide portion. In order to restrain a slack of the protective tube of the bending portion, a portion of this protective tube intermediate the opposite ends thereof is fixed to the outer periphery of at least one of the inner structure of the insertion portion, the inner structure of the bending portion and the connection portion.

An endoscope includes an electric device attached to a rigid portion provided at a distal end of the endoscope, and signal conductors extending from the electric device. The signal conductors are bent at a bending portion of the endoscope so as to reduce a bending resistance of the bending portion. Each signal conductor has an intersecting portion extending in a direction intersecting the longitudinal direction of the bending portion. A jig for processing or bending the signal conductors includes a plurality of pairs of first and second engagement portions provided on each of opposite sides of the jig. The first engagement portions as well as the second engagement portions arre arranged in a row, and spaced from one another in the longitudinal direction of the jig. Each pair of first and second engagement portions are disposed in a straight line intersecting the longitudinal direction of the jig.

A method of reverse development for depositing the toner particles to the light potential area of a photosensitive member. The developer used contains magnetic carrier particles and toner particles. An alternating electric field is formed in the developing position or zone. A relative volumetric ratio Q (%) of the magnetic carrier particles in the developing position satisfies 15.0.ltoreq.Q.ltoreq.28.0. The relative volumetric ratio is defined asQ=(M/h).times.(1/.rho.).times.C.sigma./(T+C)where M (g/cm.sup.2) is an amount of applied developer on a developing sleeve surface per unit area, h (cm) is a height of space in the developing position, .rho. (g/cm.sup.3) is a true density of the magnetic carrier particles, C/(T+C) (%) is a weight ratio of the carrier particles in the developer on the surface of the sleeve, and .sigma. is a ratio of a peripheral speed of the sleeve relative to the peripheral speed of the photosensitive member.

Provided is a control apparatus for an internal combustion engine, which can adequately perform the control of a fuel injection amount even when an abnormality, a disconnection or the like of a fuel pressure sensor occurs and thereby accurate fuel pressure information is not able to be obtained.A fuel injection valve (26) is provided which is capable of directly injecting fuel into a cylinder. If a target fuel injection amount is smaller than a minimum fuel injection amount that is minimum and is capable of injecting during one opening and closing operation of the fuel injection valve (26), the start timing of fuel injection is set within a period in which an exhaust valve is opened during an exhaust stroke.
