Title: Electrophotographic receptor
Inventor: YAMADA ASHIHIKO
IPC: G03G15/00
Filed: 1979-03-07
Abstract: PURPOSE: To obtain positive-positive and negative-positive images simply through changing over  of charging polarities by the use of the same developer by adding a resistance-control agent to the  intermediate insulation layer of the electrophotographic receptor subsequently laminating an intermediate insulation layer, photoconductive layer and surface insulation layer on a conductive substrate.  
     CONSTITUTION: An intermediate insulation layer 2 whose specific resistance is 10 10 W10 13 Ωcm is  formed on a conductive substrate 1 by adding a resitance-control agent (such as tetraheptyl  ammonium salt) to an organic macromolecular compound such as polyester of good charge carrier injection blocking characteristic. Next, a photoconductive layer 3 such as amorphous Se is  formed on the layer 2 and a surface insulation layer 4 thereon by polyester or the like, whereby  the photoreceptor is made. The layer 4 of this photoreceptor is subjected to charging to positive  or negative by the first corona discharger 5 then to uniform exposure 6 thence to charging to the  polarity opposite from the first with the second corona discharger 7, after which it is subjected to  the image exposure 9 of the original 8 to be formed with electrostatic latent images which are then  developed with toner 10, whereby the positive images are obtained when the first charging is positive and the negative images when it is negative, the latter owing to the peripheral electric field  effect. However, to obtain wide region negative images, the good images may be obtained if a developing electrode is used.

Filed: 1996-02-14
Abstract: PROBLEM TO BE SOLVED: To avoid engine speed from exceeding tolerance limit speed by change- over delay of a valve opening and closing characteristic at the time of shift down. SOLUTION: Engine speed after speed change is predicted (S3) at the time when a speed change demand of shift down is issued (S1, S2). Additionally, whether a valve opening and closing characteristic is required to change from for low speed over to for high speed or not is discriminated (S4) in accordance with engine speed after speed change predicted as mentioned above in the case when shift down is carried out. Hereby, in the case when change-over of the aforementioned valve opening and closing characteristic is required, change-over of the valve opening and closing characteristics are immediately started (S5), and starting of speed change is delayed (S6, S7) until change-over of the valve opening and closing characteristics is finished.
