摘要:
Disclosed is an image pick-up device which uses a charge transfer type solid state image pick-up device, and further is provided with a shutter so as to form a high quality picture signal in such a manner that the smear is prevented by prohibiting the incidence of the light on the device while the charge is transferred in the device. Further, the device is driven by a clock signal for still photographing in order to obtain a high quality picture information for one frame surely. Further, the photographing parameter is automatically changed over or the monitor is changed over between the motion picture photographing mode and the still photographing mode.

In a photoelectric converting apparatus having a plurality of photosensors divided into an opening portion and a light shielding portion, a carrier eliminating structure to block the inflow of photosignals from the opening portion is provided between the photosensor in the light shielding portion and the photosensors in the opening portion. The photosensor comprises of a photoelectric converting transistor having a control electrode region to accumulate the carriers generated by the light excitation. The carrier eliminating structure has the same constitution as that of the photosensor. The potential of the control electrode region is fixed to a constant potential so as to attract the carriers from the opening portion.

In an optical operation apparatus, a light source emits a light intensity-modulated on the basis of a first electrical signal. A modulating device receives the light from the light source and intensity-modulates the light on the basis of the first signal, and a photoelectric converting device converts the light modulated by the modulating device into a second electrical signal. These functions are carried out by any of a number of different arrangements of filter elements, and electro-optical or acoustico-optical devices can be used for intensity modulation.

A radiation sensing device includes radiation sensor for generating an electrical indication indicative of the distribution pattern of received radiation, a storing device for storing the electrical indication generated by the sensor, and a read-out device for reading out the stored electrical indication from the storing device. The sensor includes a first plurality of sensing elements, while the storing device includes a second plurality of storage elements. The second plurality is fewer than the first plurality.

An image signal processing method and apparatus for practicing the method are capable of identifying and differentiating information not having tonal rendition such as characters and linetone images from information having tonal rendition such as photographs and pictures, based on the difference of signal characteristics, for example based on the fact that the spatial frequency distribution in portions of an image not having tonal rendition are in the higher frequency range compared to that of the portions of the image having tonal rendition. The method and apparatus are also capable of conducting different processes on the identified different images.

This disclosure describes an apparatus for interferometrically measuring the physical properties of test object in which a test object having at least two surfaces and a substantial thickness is illuminated by a source of broadband light beam, each of plural wave fronts then formed and having an optical path difference therebetween is split by the transmission of the light beam or by the reflection of the light beam thereby, the split wave fronts are superposed each other respectively to form broadband light interference fringes and the physical properties such as thickness and refractive index of the test object are measured from the broadband light interference fringes, and which is especially provided with means for forming broadband light interference fringe by superposing the split wave fronts tilted to each other, while forming an image of said test object in the position where said interference fringe is formed.

A method of preparing synthetic resin film having high writability and printability which comprises the steps of (I) carrying out reaction by either of the following two processes:The process A of reacting together1. alicyclic polybasic acid or anhydrides thereof, (2) polypoxides containing at least two epoxy groups and (3) a compound selected from the group consisting of (a) unsaturated monobasic acid, (b) glycidyl compounds containing a radical polymerizable unsaturated bond and (c) unsaturated polybasic acid.The process B of reacting together1. at least one compound selected from the group consisting of (a) polyepoxides containing at least two epoxy groups and (b) alicyclic polybasic acid or anhydrides thereof and (2) compounds containing vinyl and hydroxyl groups in the molecule; (II) mixing the unsaturated polyester compounds obtained in above process with fillers; (III) coating the mixture on the surface of synthetic resin film; and (IV) subjecting said coating to photopolymerization by irradiating ultraviolet rays.
摘要:
Data is compressed using content addressable memory without disruption despite error using a plurality of content addressable memories to detect sequentially repeating data elements of the data. Compression information is generated for each sequence of repeating data elements that repeat for at least a compression threshold without any one of the plurality of content addressable memories generating an indication of an error for a matching content addressable memory entry. Individual data elements are output for each of the data elements that do not repeat for the compression threshold. Compression information is generated for each sequence of repeating data elements that repeat for at least the compression threshold and then generating a currently searched data element that matches the repeating data elements when any one of the plurality of content addressable memories generates an indication of an error for a content addressable memory entry that matches the currently searched data element.
摘要:
Data encoded by replacing each of a plurality of characters with bit strings is received. On the basis of definition information, at least one of the characters is recorded as corresponding to each of the bit lengths, and decode information is generated based on the number of characters, wherein the decode information includes bit string information for sorting the bit strings in a bit length order that is a predetermined order associated with bit lengths. In response to receiving a particular bit length, character information in which the characters are sorted in the bit length order is generated by inserting a character corresponding to the particular bit length into a position corresponding to the particular bit length in an array in which at least one of the bit lengths.
