摘要:
A device for the pressure fixing of a toner image contains a pair of pressure fixing rolls arranged in parallel to each other. An image record carrier is fed in between said pressure fixing rolls which, for the pressure fixing of the toner image, are pressed against each other through a pressure bar by means of a plurality of pressure generators. Said pressure generators are positioned displaceably in the axial direction of said pressure fixing rolls to adjust a load distribution depending upon the width of said record carrier.

A photoconductive member for electrophotography wherein an electric field is established across a light amplification layer comprising a first transparent electrode, a field-effect light-emitting layer, a second photoconductive layer and a second electrode after the first photoconductive layer has been uniformly charged when a light image impinges on the first photoconductive layer, the portion of the field-effect light-emitting layer corresponding to the light image emits light to the first photoconductive layer, whereby an electrostatic image is formed on the first photoconductive layer by both the light image impinged thereon and the light emitted from the field-effect light-emitting layer.
摘要:
After uniformly charging one insulator side of an insulator mesh the other side of which is subjected to electroconductive treatment, the ion flow controlled by recording signals is irradiated for a short period of time on the insulator mesh to obtain a charge distribution wherein the charge on the insulator side is neutralized corresponding to the dots to be recorded. Via mesh apertures which have been freed from the charge by neutralization, the ion flow is irradiated for a time far longer than the above-said short time on an insulating recording substrate, to obtain thereon an electrostatic latent image having an amplified charge distribution.

An L-amino acid can be produced by culturing a bacterium which belongs to the Enterobacteriaceae family, and has an enhanced ability to use a fatty acid. The bacterium is capable of producing the L-amino acid in a culture medium containing a fatty acid or a hydrolysate of an oil-and-fat as a carbon source, thereby producing and accumulating the L-amino acid in a culture.

An image pickup device provided on a base board, comprises an image pickup element provided on the base board and including a photoelectrically converting section in which pixels are arranged, a peripheral surface formed around the photoelectrically converting section and a side surface crossing the peripheral surface; an optical member including a lens section to form an image of an object onto the photoelectrically converting section of the image pickup element, a leg section to support the lens section and a contact surface to be brought in contact with the image pickup element, wherein the lens section, the leg section and the contact surface are made in a single body. The optical member is mounted on the image pickup element such that the contact surface is brought in contact with the peripheral surface or with a surface member when the surface member is provided on the peripheral surface.
摘要:
A camera for taking photographs by voice recognition operations. The camera comprises a microphone through which voiced command words of an operator are registered in a computer as a form of digital data. The computer identifies the same voiced command words in accordance with the registered data and operates the intended functions of the camera. The camera indicates the functioning of the computer for the registration and the recognition of the voiced command words with a display device so that the operator can confirm his operations on the camera.
摘要:
A range finder for measuring the distance of an object to be measured by the steps of radiating the spot light to the object, forming an image of the reflected ray of light by image forming means and measuring the distance of the object from the output of an element which is disposed at a position substantially corresponding to the image forming position and of which output varies in accordance with the light-receiving position on the light-receiving surface. PSD are used as the element. A focussing detector which includes a semiconductor position detection element PSD placed at a position corresponding to the film surface in a camera or the like and detects the focussing state on the basis of the electric output from the semiconductor position detection element PSD. A focussing detector which comprises image forming means for forming the image of an object; a PSD disposed in such an arrangement that the light-receiving surface thereof is eccentric with respect to the optical axis of an optical system including the image forming means and disposed at the back of the image forming means; and an operation circuit detecting the extreme values of the output of the PSD and producing a focussing signal.
