Title: Approximating device for discontinuous broken line of full curvature function
Inventor: KATO REIKO
IPC: G06F7/548
Filed: 1986-02-05
Abstract: PURPOSE:To extract the flexion points, i.e., the features of the form of the spot train data on a 2-dimensional plane with high performance, by using a discontinuous point extracting part that extracts the segments of large gradient with priority as the discontinuous points out of a continuous broken line in case a broken line is approximated with another broken line including the discontinuous points. CONSTITUTION:Both the S direction displacement DELTASi and the theta direction displacement DELTAthetai are obtained to each segment Qi (points Pi-Pi+1) contained in a continuous broken line and the priority is set in the order of larger absolute value of the segment gradient ti(=DELTAthetai/DELTASi). The discontinuous points are extracted to the segments having DELTASi smaller than the threshold value in the order of priority. The positions of discontinuous points are set at the medium point of each segment like a case of a conventional device. However new discontinuous points are not extracted and integrated with those discontinuous points already extracted in case one of both segments connected to a noticed segment is already extracted as the discontinuous points. Then the noticed segment is not extracted as the discontinuous points in case both adjacent segments connected to the noticed segment are already extracted as the discontinuous points.

IPC: F27B7/16
Filed: 1994-02-22
Abstract: PURPOSE:To flatten element frequency response by improving the non-flatness of the frequency response at the low frequency (<GHz) of an optical semiconductor element. CONSTITUTION:Buffer layers consisting of superlattice are arranged at the boundaries between an undoped layer 2 and doped layers 1, 3.

Abstract: PROBLEM TO BE SOLVED: To reduce the low pressure-side piping resistance to reduce the in-pipe flow velocity of return oil and improve the efficiency of a hydraulic circuit by returning the return oil discharged from an actuator to a tank through two routes. SOLUTION: When a pump port 52 and a tank port 54 are allowed to communicate with a port 56 and a port 58, respectively, by switching a directional control valve 50, a hydraulic fluid is supplied from a pump 20 through a piping 32 to operate an actuator 30. The return oil discharged from the actuator 30 is passed through a piping 34 and discharged from a common return pipe 42 to a tank 40. Since the hydraulic fluid to be supplied has a pressure higher than the return oil, a return pipe selector valve 60 connects a return pipe 38 to a tank port 66 to be allowed to communicate with the common return pipe 44.  At this time, the return oil is discharged through two routes of the route extending from the piping 34 to the tank through the common return pipe 42 and the route extending from the piping 34 to the tank 40 through the return pipe 38 and the common return pipe 44, so that the piping resistance and in-pipe flow velocity of the return oil can be reduced.

Filed: 1984-02-14
Abstract: PURPOSE:To prevent positional error of a perforation in a printed plate out of tolerance limit by providing drill-breaking plate for breaking a drill whose positional error is out of the tolerance limit. CONSTITUTION:A drill-breaking plate 2 is formed of a metal plate or insulating plate having a perforation at a position corresponding to a perforating position on a printed plate to be perforated, and the perforation 2a has a diameter D of the amount of a predetermined hole diameter d that is drill diameter and positional allowable error and is formed by etching, drilling or the like.

CONSTITUTION:A photosensitive layer formed on a conductive substrate contains an azo compd. excellent in photoconductivity represented by formula [ I ] in which Q1, Q2 are each alkyl, alkoxy, ester, or optionally substd. phenyl; Y1, Y2 are each H, halogen, cyano, alkyl, or alkoxy; n is an integer of 0-2; A is one of formulae II-V; Z is an atomic group necessary to form an optionally substd. aromatic carbon ring or aromatic hetero ring; Q3 is optionally substd. carbamoyl or sulfamoyl; R1 is H, optionally substd. alkyl or amino or carbamoyl, carboxy, its ester, or cyano; a' is optionally substd. aryl; and R2, R3 are each optionally substd. alkyl or aralkyl or aryl. A photosensitive body can be obtained by forming on the conductive substrate the photosensitive layer formed by dispersing this azo compd. into a binder, but especially excellent results can be obtained by utilizing its especially excellent carrier generating ability and using it as a carrier generating material in combination with a carrier transfer material, and thus forming a so-called functionally separated type photosensitive body. This type photosensitive body may be of a dispersion type, but it is preferred to form a laminated type photosensitive body of a carrier generating layer and a carrier transfer layer.
