摘要:
An image forming apparatus and an image forming method are characterized in that charged particle jumping can be controlled by applying signals having a small potential difference, and that low-voltage type switching devices can be used as switching devices for the power source. Control electrodes 16 are provided to move charged particles detached from a development roller 2 and to control the movement amount of the charged particles by generating a transfer electric field directly or indirectly between the development roller 2 and a rear electrode 8. A bias electrostatic field is generated between the development roller 2 and the control electrodes 16 by applying a voltage under a jumping start voltage, which is a voltage having the polarity opposite to the polarity of the charged particles and is lower than the jumping start voltage for detaching the charged particles from the development roller 2.

In an electric vehicle having front wheels braked by regenerative braking and hydraulic braking and rear wheels hydraulically braked, it is possible to check the magnitude of the regenerative braking force easily and accurately, by using a two-axle chassis dynamometer. Assuming that the front wheel braking force F.sub.2 ' detected by the chassis dynamometer is the total braking force C.sub.2 ' of the front and rear wheels, the total braking force C2' is broken down into component forces according to braking force distribution ratio data previously stored in a memory, to calculate a reference regenerative braking force A.sub.2 'D.sub.2 '. Based on the actually detected pedal depressing force A.sub.2 and the distribution ratio data, an imaginary pedal depressing force A.sub.2 ' is calculated that is required to produce a total braking force of the driven wheels and follower wheels equal to the braking force F.sub.2 ', generated by the driven wheels in the actual pedal depressing force A.sub.2. Based on the imaginary pedal depressing force A.sub.2 ' and the distribution ratio data, the imaginary regenerative braking force A.sub.2 'D.sub.2 ' that is produced by the driven wheels in the imaginary pedal depressing force A.sub.2 ', is calculated and then compared with the reference regenerative braking force A.sub.2 'D.sub.2 '.
摘要:
A transfer member includes a dyeing layer transfer member, which has a lubricating heat-resistant layer on the reverse surface of a first base material and laminated layers of a parting layer and a dyeing layer on the obverse surface, an ink transfer member, having a lubricating heat-resistant layer on the reverse surface of a second base material and the laminated layers of an adhesive layer and an ink layer, an intermediate member having a functional layer on a third base material, and an image-receptor. A thermal transfer printing method includes the steps of thermally transferring the dyeing layer onto the functional layer by setting a thermal head in contact with the lubricating heat-resistant layer of the dyeing layer transfer member, thermally transferring dye of the ink layer onto the dyeing layer that was transferred onto the functional layer in response to picture signals by setting the thermal head in contact with the lubricating heat-resistant layer of the ink transfer member, and thermally transferring the dyeing layer recorded with the dye onto the main surface of the image-receptor. Thus, pictorial images of high quality are formed on the image-receptor, and thermal transfer printing can be carried out repeatedly and stably.

A thermal printing apparatus includes an intermediate medium. A color developing layer transfer member includes a first base member and a color developing layer on a surface of the first base member. A dye layer transfer member includes a second base member and a dye layer on a surface of the second base member. The dye layer contains dye. At least a part of the color developing layer is transferred from the color developing layer transfer member onto the intermediate medium in response to at least one of heat and pressure. The dye is transferred from the dye layer of the dye layer transfer member onto the color developing layer on the intermediate medium to form a recorded picture on the color developing layer in response to both heat and pressure while the dye layer on the dye layer transfer member and the color developing layer on the intermediate medium are in contact with each other. The color developing layer with the recorded picture is transferred from the intermediate medium onto an image receptor. A releasing device is operative for implementing separation between the intermediate medium and one of the color developing layer transfer member and the dye layer transfer member. The releasing device includes a releasing blade and a belt support member associated with the releasing blade. The releasing blade engages one of the color developing layer transfer member and the dye layer transfer member. The belt support member supports the intermediate medium along one of a flat plane or an outwardly-projecting plane.
摘要:
An electric pump is turned ON and OFF by a main drive circuit including a negative pressure sensor for detecting a negative pressure in an accumulator, a first relay and a control device, and also turned ON and OFF by a back-up drive circuit including a negative pressure switch for detecting a negative pressure in an accumulator, and a second relay. For a period from the starting of the electric pump by the back-up drive circuit to the stopping of the electric pump by the main drive circuit, there is a period during which the electric pump is being driven only by the back-up drive circuit and a period during which the electric pump is being driven only by the main drive circuit. For each of these periods, a trouble of the main drive circuit and/or the back-up drive circuit can be determined by reference to a check signal indicative of the operational state of the electric pump. Thus, it is possible to reliably detect a trouble with the driving of the electric pump connected to the accumulator.

A thermal transfer printing method, in a combination of a transfer medium including a support on which at least a dyeing layer and a dye anti-diffusion layer (and a protecting layer) are provided separately from color layers, an intermediate medium, and an image-receiving medium, comprising steps of: transferring at least the dye anti-diffusion layer and the dyeing layer (and the protecting layer) onto the intermediate medium, thereby forming a sequential laminate on the intermediate medium; printing a thermal transfer image in the dyeing layer of the laminate formed on the intermediate medium; and transferring the laminate carrying the thermal transfer image thereon from the intermediate medium onto the image-receiving medium (and fixing it simultaneously, or after transferring), thereby finally forming a print image on the image-receiving medium. A novel image-forming layer transfer medium used in the above thermal transfer printing method, has various properties in area of each layer, thermal characteristics, arrangement of respective layers etc. According to the printing method and the image-forming layer transfer medium, the print image obtained causes no contamination by dyestuff and print density is not lowered by the loss of dyestuff, bringing high-temperature stability in maintaining the transfer medium in a wound condition, and/or realizing a low-temperature transfer operation of the image-forming layer onto the image-receiving medium.
