摘要:
An electrophotographic light-sensitive material is described, comprising an electrically conductive support, an amorphous silicon photoconductive layer on the support, and a layer of amorphous material containing at least carbon and halogen atoms is provided on the photoconductive layer. This material is free from a serious reduction in resolving power as is encountered in conventional electrophotographic light-sensitive materials when they are exposed to corona discharge, particularly negative corona discharge under high temperature/humidity conditions.

摘要:
A radiation image read-out apparatus comprises a linear stimulating ray source for emitting stimulating rays to a linear portion of a stimulable phosphor sheet carrying a radiation image stored therein, and a line sensor constituted by many solid state photoelectric conversion devices. The line sensor extends at least over the length of the linear portion of the stimulable phosphor sheet exposed to stimulating rays. Light emitted by the linear portion of the stimulable phosphor sheet upon stimulation thereof is received and photoelectrically converted by the solid state photoelectric conversion devices. The portion exposed linearly to stimulating rays and the line sensor are moved with respect to the stimulable phosphor sheet, and outputs of the line sensor are sequentially read out in accordance with the movement of the portion exposed linearly to stimulating rays and the line sensor with respect to the stimulable phosphor sheet.

A radiation image read-out apparatus comprises a stimulating ray source constituted by many point light sources for sequentially emitting stimulating rays onto a portion of a stimulable phosphor sheet carrying a radiation image stored therein, and a line sensor constituted by many solid state photoelectric conversion devices. The line sensor extends over the length of the portion of the stimulable phosphor sheet linearly exposed to stimulating rays. Light emitted by the exposed portion of the stimulable phosphor sheet is received and photoelectrically converted by the solid state photoelectric conversion devices. The stimulating ray source and the line sensor are moved with respect to the stimulable phosphor sheet in a main scanning direction normal to the array of the solid state photoelectric conversion devices, and then moved with respect thereto in the array direction each time one main scanning step is finished.

A radiation image read-out system comprises a point-source light for projecting a spot of stimulating rays onto a stimulable phosphor sheet carrying a radiation image stored therein, and a solid state photoelectric converter which is opposed to the spot-like portion of the stimulable phosphor sheet exposed to the spot of stimulating rays and is adapted to receive light from the spot-like portion. The point-source light and the solid state photoelectric converter are moved with respect to the stimulable phosphor sheet to two-dimensionally scan the stimulable phosphor sheet, thereby reading out the radiation image stored therein.
摘要:
A method for reading out signal charges in a solid-state image pickup unit providing either an improved resolution for a constant vertical integration density or a reduced vertical integration density while maintaining the same resolution. The photoelectric conversion elements of the unit are arranged in a matrix of rows and columns with m rows of photoelectric conversion elements being assigned to each scanning line. Signal charges generated in the photoelectric conversion elements during exposure are transferred to a vertical transfer section in the order of the m-th row to the first row in each scanning line, and then the charges are transferred to a horizontal charge transfer section using a four-phase driving method.

A method for producing a solid-state imaging device comprising a plurality of unit pixel sections, including a first unit pixel section, is provided. The method includes the steps of forming a first conductivity type well region of the first unit pixel section on a second conductivity type semiconductor layer provided on a first conductivity type semiconductor layer, the first conductivity type well region including a light receiving region for generating charges corresponding to an amount of light incident thereon and a charge transfer region capable of transferring the charges; and generating a charge accumulation region, for accumulating the charges generated in the light receiving region, in the charge transfer region. The step of forming the first conductivity type well region includes the step of implanting impurities such that the light receiving region and the charge transfer region in the first conductivity type well region have a substantially uniform impurity concentration.
摘要:
A range finding device having a lens holder with two tunnels, and two lens plates mounted in front of the tunnels. Two pins are formed on the front surface of the lens holder, the two pins being positioned on vertical positioning lines externally of the vertical center lines of the two tunnels. Each lens plate has an elongated hole extending in the direction of the vertical positioning line, a pin being inserted in the elongated hole. In a preferred embodiment, each lens plate has four holes formed therein. Two of the four holes are used for coupling with two pins. Of these two holes used for positioning, one is a round hole and the other is an elongated hole.
摘要:
An electronic still camera wherein midway through an exposure the charge signals impressed by incident light on an imaging section are transferred to a storage array while the exposure continues. Corresponding signals on the imaging array and the storage arrays are differenced to form error signals which are added to or subtracted from the two original signals before they are combined.
