Title: Distance measuring device
Inventor: TAKAGI MASAAKI
IPC: G01C3/00
Filed: 1983-06-03
Abstract: PURPOSE:To stop driving a lens once potentials at input terminals of a comparator become coincident with each other when the output of one photodetecting circuit attains to some set value, by varying the light emission frequency of a light emitting element to the center frequency of a band-pass filter circuit. CONSTITUTION:Output processing circuits of photodetecting elements 23 and 24 incorporate BPFs 27 and 28. The light emission frequency of the light emitting element 22 is varied to the center frequency of the BPFs within a specific time. When the output Vj of one photodetecting element circuit attains to some set value, the output state of the other photodetecting element circuit is stored as a voltage value and supplied to the inverted input terminal of the comparator 43. While the photographic lens is driven from its limit value to the other limit value, the potential (+) at the other input terminal of the comparator circuit is swept from the limit value to the limit value, and the photographic lens is stopped from being driven when the potentials at both input terminal coincide with each other. Thus, the distance measurement state is discriminated stably through such constitution that the light emission frequency of the light emitting element is varied to set the photographic lens at the specific position.

Title: Floating point arithmetic processor
Inventor: JIEFURII DAGURASU BURAUN
IPC: G06F7/38
Filed: 1990-04-17
Abstract: PURPOSE: To shorten the required time by checking decimal and exponent results of floating-point processing in floating-point multiplication and addition/ subtraction to check whether normalization and rounding processing can be skipped or not and shortening the succeeding processing at the time when required conditions are satisfied. CONSTITUTION: A new function to discriminate whether normalization and rounding processing are requested or not is given to a control logic 11. When the operation processing is addition of two numbers of the same sign, subtraction between two numbers having different signs, or multiplication, the most significant bit of the resultant decimal is checked, and a normalization request is completely forecasted by the result to determine whether normalization is not necessary at all, it can be executed by one-bit left shift, or it can be executed by one-bit right shift. Decimal and exponent results are checked to discriminate whether rounding processing is required or not; and the result is transferred to a floating-point register 14 when normalization neither rounding processing is not necessary. Thus, steps of normalization processing and rounding processing can be skipped to increase the operation processing speed.

Filed: 2022-02-23
Abstract: The invention belongs to the field of material processing and relates to the use of laser light to remove material from a workpiece and can be applied to the processing of transparent media, including glass. The laser radiation transforming device has a photonic element consisting of a transparent material base, the input and output planes which are arranged parallel to each other. There is a structural modification in the base volume of the transparent material between the input and output planes of the photonic element or at the surface of the photonic element. The structures recorded in or on a photonic element are geometric Pancharatnam-Berry phase structures with uniformly varying angles of their orientation, which at each point of the beam cross-section gives the change function of the orientation of the structures v = f (ϕ, r), where ϕ is the azimuthal angle of the element’s coordinates, varying from -π to π, and r is the radial coordinate. The polarization angle change function v = f (ϕ, r) is created in such an oscillating form that when the radiation exiting from the photonic element is focused, a photonic needle of the desired shape is formed, regardless of the polarization direction of the incident light field.
