Abstract: A high-resolution image sensor uses integrated arrays of photosensitive elements in connection with a lens system which projects, onto the arrays, an erect, unmagnified, unreversed real image of the object being sensed (such as a line of a document). The arrays are staggered in two or more rows so that a single, large integrated array need not be used, yet the entire width of the document line can be covered by photosensitive elements while a 1:1 ratio is maintained between object size and image size. The real image is produced on the two or more rows of arrays by two or more optical systems which have a large depth-of-focus to allow for some variation in object distance. The sensor has a high image quality and is capable of detecting color.

Abstract: An unrecorded portion detecting apparatus for a record player. The apparatus has a device such as light-emitting diode for applying light to disc surface and a pair of light-sensitive devices such as phototransistors for sensing light reflected by the disc surface mounted on the tone arm. The pair of light-sensitive devices are separated from each other along a tracing line of the tone arm. The apparatus further has a circuit for producing a detecting signal at the time when the tone arm detects the unrecorded portion, resulting in an output signal from the leading device of the pair of light-sensitive devices. The circuit includes means for uniforming levels of the output signals of the pair of the light-sensitive devices under the same condition, means for differentiating the uniformed signals by a predetermined extent and means for comparing level relationship between the output signals.

Abstract: A computer system includes a memory appearing to a user to have representative addresses and non-representative address. The data word is accessed in parallel at the representative address and a data bit of the representative address is fetched from a non-representative address of memory. The computer system is implemented by using the lower three bits of the address from the CPU to identify the location of the bit in the word; the address of the word in memory is the upper bits of the address from the CPU.

Abstract: In a mark position-detecting apparatus, a rectangular reference mark is performed on a workpiece or photomask. The apparatus includes a movable table for supporting the photomask, a stationary light source for radiating light for forming a light spot on the photomask, a photodetector for detecting a change in light component transmitted through the mask, and a computer control section. The table moves forwardly and reversely in a Y-direction so that the photodetector scans two opposite edges of the reference mark in opposite directions in the Y-direction. The table is then moved forwardly and reversely in a X-direction so that the photodetector scans other two opposite mark edges. The signal detector thus produces edge position data representing the four mark edge scanned. The computer control section computes the coordinates of the mark center based on the edge position data.

Abstract: An optical disc apparatus is disclosed, which comprises an optical head for obtaining an information signal from an optical disc through photoelectric conversion and an accessing section for moving the optical head to a position corresponding to a desired track of the optical disc.
