Abstract:
A semiconductor optical logical device comprises two light-emitting elements (2a, 2b) formed on one main surface of a transparent substrate (1), and two light sensitive elements (3a, 3b) formed on the other main surface faced to the light emitting elements (2a, 2b), respectively. The two light sensitive elements (3a, 3b) are comprised of amorphous semiconductor and are electrically connected in series. On the other hand, the light-emitting elements (2a, 2b) are driven responsive to individual input signals, respectively. If and when two input signals are applied simultaneously, the two light-emitting elements (2a, 2b) emit light simultaneously, so that an output is obtained from the two light sensitive elements connected in series. If and when only one input signal is applied, no output is obtained. Thus, an optical logical product circuit is provided.

Abstract:
The invention discloses a novel flat display panel suited for use with computer terminal equipment, television sets, or the like. The flat display panel first confines light in a core layer of a light wave guide, and then diminishes refractive index in part of the core layer by applying a specific vltage to it. Light transmitted from part of the core layer having diminished refractive index is then outputted outside from the light wave guide. Using the externally outputted light, the flat display panel displays figures. The flat display panel embodied by the invention minimizes the total thickness of the display panel itself. It effectively allows display of figures in a sizable visual area, and yet, allows display of figures at an extremely fast speed as well.
Abstract:
An electrostatic latent image forming apparatus includes a dielectric drum (10) a surface of which is uniformly charged in a predetermined polarity by a charging corotron (16). A recording head (18) includes a transparent base plate (30), a transparent electrode (32) and a photoconductive layer (34) composed of an amorphous silicon are formed on the transparent base plate in this order. A plurality of discharging electrodes (36) are formed on the photoconductive layer. A bias voltage (46) having a reverse polarity of the charged polarity being charging by the charging corotron is applied. When a light signal in accordance with an image to be formed is entered on the back surface of the transparent base plate, carriers, that is, holes and electrons are generated in the photoconductive layer, the carrier having the same polarity as the bias voltage is discharged onto the dielectric drum through the discharging electrodes. Electric charges are removed or reduced at a portion on the dielectric drum where such discharge occurs, and therefore an electrostatic latent image in accordance with the light signal being entered is formed on the dielectric drum.
Abstract:
An electrostatic recording apparatus comprises a photosensitive drum. The photosensitive drum comprises a bulk layer of amorphous silicon formed on a support, and in the bulk layer, a first layer region is formed at the support side and a second layer region is formed at the surface side. The first layer region is formed in a manner of comprising hydrogen of 0.01-40 atomic %, oxygen of 0.1-40 atomic % and boron of 5.times.10.sup.-6 -1.0 atomic %. On the other hand, oxygen and boron are not doped virtually in the second layer region and generation of carrier traps is suppressed in this non-doped second layer region. Furthermore, the peak wavelengths of the lights irradiated onto the photosensitive drum from both a light source for exposure and light source for discharge are set shorter than 650 nm, and preferably shorter than 600 nm. Light of short wavelengths shorter than 650 nm is almost absorbed in the second layer region, and generation of carriers in the first layer region is small, and thereby capture of carriers in traps is suppressed.
