摘要:
The electrostatic information recording medium of the invention has on at least an electrode an information recording layer comprising a product obtained by contact of a polymer having a fluorine-containing aliphatic ring structure with fluorine gas, on which layer a latent image charge trap is retained. This electrostatic information recording medium enables electrostatic information such as an electrostatic latent image to be recorded in the form of a charge trap rather than an electrostatic charge, and so may be used as an electrostatic printing master by way of example.
摘要:
A charge carrier medium 1 including an insulating layer 11 laminated on an electrically conductive layer 12 with an electrostatic latent image 2 recorded on the insulating layer 11 is brought into contact with water, etc., to resurrect the attenuated potential. Alternatively, the charge carrier medium 1 is previously immersed in water, etc., to deposit onto the surface thereof charges opposite in polarity to those of the electrostatic latent image 2 generated by charging, thereby attenuating the surface potential. This makes any external access to the image information impossible. In reading the image information, a PET film 5 or the like is brought into close contact with the surface of the charge carrier medium 1, and is then peeled apart from that surface to remove the charges of the opposite polarity and thereby resurrect the image information for reading. This makes it possible to protect the image information against a third person's access thereto and provide an assured reproduction of the electrostatic latent image.

In the information recording an reproducing method and apparatus according to the present invention, a piece of picture image information is recorded as an analog quantity or a digital quantity an information carrying medium in a planar manner at a high density, charge potential is read for outputting electric signals to correspond to the recorded picture image information and then the outputted signals are printed out by means of various display unit or output device, with high quality and high resolution as well as ease processing of the information. The information carrying medium provides a long period of storage of information and enables stored picture image information to be repeatedly reproduced with a picture quality according to need. Particularly, it is, according to the present invention, possible to read and output local potential of an information carrying medium with predetermined scanning density at a desired time, and so pictures of high quality may be output as a silver salt photograph is taken and reproduced by optically scanning the film. Thus, the present invention may be applied to a wide field including photographing, copying and printing.
摘要:
A master electric charge retaining medium 2 having electrostatic charge information recorded thereon is disposed face-to-face with a reproductive electric charge retaining medium 3, and a voltage is applied between the respective electrodes of the two electric charge retaining media to induce an electric discharge, thereby inversely reproducing the electrostatic charge information on the reproductive electric charge retaining medium, as shown in FIG. 2(b). It is possible to effect the reproduction any number of times while preventing the lowering in the contrast of the master electric charge retaining medium by making the electrostatic capacity of the master electric charge retaining medium adequately larger than the electrostatic capacity of the reproductive electric charge retaining medium. In addition, a master electric charge retaining medium 2 having an insulating layer with a relatively high softening point and a reproductive electric charge retaining medium 4 having a thermosoftening resin layer 4a are disposed face-to-face with each other to induce electric charge on the thermosoftening resin layer in correspondence to the electrostatic charge image on the master electric charge retaining medium 2, and the thermosoftening resin layer is softened by heating to form a dimple pattern thereon, thereby enabling transfer development to be effected any number of times without leaking the electrostatic charge.

Plastic-worked lumber. PW1 and PW2 has air-dried specific gravity twice or more than those of lumber before processing NW1 and NW2 and acute crossing angles within a range of 45 degrees or less. The acute crossing angles are formed by all of annual ring lines RL on a butt end surface of the plastic-worked lumber PW1 or PW2 and a heart-side cross grain surface or a pith-side straight grain surface of the plastic-worked lumber PW1 or PW2. The plastic-worked lumber PW1 and PW2 is prepared by heating and compression to lumber NW1 or NW2 so that the lumber NW1 or NW2 is heated and compressed in a thickness direction thereof and plastically worked.

摘要:
A charge carrier medium (41) is successively fed to a rotating (or reciprocating) photosensitive material (40) in opposite relation thereto. Making use of a beam or linear slit scanning exposure system or a planar exposure system enabling one frame to be scanned every 1/60 sec., for instance, the exposure timing is allowed to synchronize with the movement of the photosensitive material (40) and the feed of the charge carrier medium (14) to record images successively on the medium by either voltage-applied exposure or short-circuit exposure in which the charge carrier medium is pre-charged, whereby the images can be picked up as moving images. At the same time, the photosensitive material (40) is irradiated with light from the charge-clearing light source (45) to clear it of a residual charged image. Alternatively, such leakage of charges may be achieved by bringing an electrically conductive member into contact with the photosensitive material, charging it uniformly as by d.c. or a.c. discharge, heating it or bringing it into contact with an electrically conductive liquid or vapor, whereby the residual image on the photosensitive material is rapidly decayed to eliminate the influences of the residual image on the photosensitive material, thereby making it possible to obtain electrostatic images of high quality continuously.
摘要:
The present invention provides an image-recording process wherein the voltage applied between a photosensitive member 2 and electrostatic information recording medium 1 is put off after the lapse of a given time from the closing of an exposure shutter 13. It is thus possible to move all the generated carriers onto electrostatic information recording medium 1 and accumulate them as charges in an amount corresponding to the quantity of exposure irrespective of a voltage shutter time. It is also possible to electrically charge electrostatic information recording medium 1 or the photosensitive member 2 in advance and put on-off an electrical connection between the electrodes of the photosensitive member 2 and electrostatic information recording medium 1 to control image exposure, thereby dispensing with any external high voltage power source and obtaining a positive image. In addition, it is possible to avoid the occurrence of inverse discharge and prevent the resulting image from falling into disorder by separating the photosensitive member 2 and electrostatic information recording medium 1 from each other, while voltage remains applied between the electrodes thereof, after an electrostatic image has been formed on the electrostatic information recording medium 1, and putting off the voltage impressed.
