Abstract:
An electric charge holding medium (41) is fed successively at a predetermined speed in such a way that the medium (41) faces a photosensitive body (40) rotating (or reciprocating) as shown in Fig. 8. Using a system of beam-scanning exposure, linear slit-scanning exposure, or whole area exposure of, for example, one frame per 1/60 second, images can be photographed as frames of an animated cartoon by synchronizing the exposure timing with the movement of the photosensitive body (40) and with the feed of the electric charge holding medium (41) and by recording pictures on the medium successively through exposing with application of a voltage or with short-circuit lightening after charging the electric charge holding medium. Further, electrostatic images of high quality can be obtained successively attenuating rapidly an after-image on the photosensitive body and eliminating its effect, by erasing a residual charge image through projecting a light on the photosensitive body (40) with a light source (45) for erasing, by performing the removal of the electric charges or uniform charging through bringing a conductive member into contact with the photosensitive body, by performing uniform charging through DC or AC discharge, or by performing the leaking of the electric charges through heating, a conductive liquid or vapor, etc.
Abstract:
A photoconductive layer (5) of a photosensitive member (1) and a charge retaining layer (6) of a charge retain medium (2) are so disposed as to face each other with a predetermined distance (d). After a power source (8) is connected, light (9) having a predetermined wavelength is irradiated to the photosensitive member (1) to form an electrostatic latent image in the charge retaining layer (6) of the charge retaining medium (2). Next, the charge retaining medium (2) is disconnected from the power source (8), toner is applied onto the charge retaining layer (6) and development and fixing are carried out. Etching is then conducted using the resulting toner image (16) as a mask to remove the portions of the charge retaining layer (6) to which the toner (16) is not deposited. In this manner a printing plate having a scanned portion formed by the toner (16) and the charge retaining layer (6) on the conductive substrate (7) can be obtained. According to this plate, the toner image is formed directly on the charge retaining layer (6) of the charge retaining medium (2). Therefore, the toner image need not be transferred and a scanned portion having high resolution can be formed.
Abstract:
A photosensitive member having an electrode on the front surface thereof and a photoconductive layer stacked on the electrode. The member faces an electrostatic data recording medium which comprises a charge-holding layer having an electrode on the back surface. The photosensitive member may be in contact with the recording medium. When a voltage is applied across the electrodes, an exposure is carried out to form an electrostatic charge pattern in the electrostatic data recording medium, the electrostatic charge pattern being in correspondence with the exposure pattern. The layer structure of the photosensitive member and the photoconductive layer and the method of forming the photoconductive layer are improved, enabling the recording of electrostatic data on the electrostatic data recording medium with high sensitivity. Further, the contrast in charges of data between the exposed portion and the unexposed portion can be improved.
Abstract:
Connector housings (11, 12) to be mounted on a printed circuit board (100) have a plurality of rows of contacts (13, 14) extending from wall surfaces of the housings (11, 12). These contacts (13, 14) are soldered to conductive pads (23) of a flexible circuit (20). The flexible circuit (20), bent in a generally U-shape, is preferably inserted by a metallic guide member (30) between rows of contacts (50) of a mating connector (40) for interconnection therebetween. The guide member (30) preferably causes a ground conductor (176) on the reverse surface of the flexible substrate to groundingly engage conductive members (43, 124) positioned at both ends of the housing. In an alternate embodiment strengthening plates may be adhered to the flexible circuit between the opposed arrays of conductive pads and ground contact pads.
Abstract:
A photoconductive photosensitive member (2) and a charge retaining medium (1), which face one another at a predetermined interval, are exposed to light while a voltage is applied between them from an external power source (E). The discharge occurring in the exposed areas produces an electrostatic image on the charge retaining medium. In this method, the applied voltage is removed a predetermined time after a shutter (13) is closed so that all the carriers generated in the photosensitive member can be transferred to the charge retaining medium. Accordingly, the quantity of charge corresponding to an exposure quantity is stored in the charge retaining medium irrespective of the kind of the photoconductive member used. If the charge retaining medium or photosensitive member is charged in advance in this case, a positive image can be obtained with the external power source disconnected. Alternatively, the applied voltage may be removed after the photosensitive members are separated from the charge retaining member on which an electrostatic charge image has been formed. In this case, the image is prevented from distortion. On the other hand, if a spacer for keeping the photosensitive member and the charge retaining member in a spaced-apart relation is formed integrally with either the photosensitive member or the charge retaining medium, the discharge gap can easily be kept constant. Further, if the electrode of the photosensitive member or that of the charge retaining medium at a spacer portion is removed, it is effective to prevent dielectric breakdown which may be caused through the spacer.
Abstract:
A monolithic sensor (10) is constituted by epitaxially growing a high-resistance compound semiconductor (12) on a low-resistance compound semiconductor (11), and further forming a reflecting dielectric film (13) thereon. The low-resistance compound semiconductor (11) has a large band gap so that the probe light is not absorbed but passes therethrough. The semiconductor (11) has a lattice constant and a coefficient of thermal expansion close to those of the high-resistance compound semiconductor, and a resistivity of smaller than 10 ohm.cm so that it can also be used for an electrode. The high-resistance compound semiconductor (12) has a large band gap so that light of a short wavelength can be used, since a change in retardation increases with the decrease in the wavelength of the probe light. The semiconductor (12) has a large electro-optical constant and a resistivity of greater than 10 ohms.cm. Therefore, a sensor is constituted maintaining good workability and very high surface accuracy permitting less optical deterioration.
Abstract:
Secondary battery reuse method in which, when used secondary battery packs G and A in a lithium secondary battery 100 have become unusable, the resistances Ri and capacities Ci of a plurality of secondary battery stacks Ni constituting the secondary battery pack G are measured (step SP12) and a reusable secondary battery stack Ji is selected and separated therefrom by comparing these measured resistances Ri and capacities Ci with a resistance threshold value H and a capacity threshold value I, respectively (steps SP13, SP14). In addition, a new secondary battery pack is rebuilt (constructed) by combining the secondary battery stack Ji with a secondary battery stack that has been determined to be reusable in the secondary battery pack A in the same manner as in the secondary battery pack G (steps SP24, SP25).
Abstract:
A data recording medium (10) is manufactured by laminating an electrode (13) and a recording layer (11) of a pinene polymer having a molecular weight of 500 ∩ 10,000 on a support (15). By thermal development, a thermally stable frost image can be produced without causing attenuation of data charge generated on the resin surface. Transmitted or reflected light can be accordingly used for reproduction of the frost image, without provision of a photoconductive layer coloration of which has bad influence. Since voltage impression exposure is made, the degree of uneveness of the frost image changes in accordance with the exposure value. Therefore, a tone wedge effect can be provided and high resolution can be obtained. It is thus possible to produce high-quality and high-fidelity OHP transparencies, microfilms, slide films, and so forth.
