摘要:
A circuit for processing a maximum value conversion and a minimum value conversion of a digital image data to extract the feature of the image. A range N.times.N of the image data is processed by a simple circuit construction which comprises a horizontal row maximum value selection circuit for selecting the maximum value along N data and N numbers of maximum value selection circuits for comparing N vertical column data with the output data of the horizontal row maximum value selection circuit.

Provided is a floor structure of a railcar in which thickness of a heat insulating material can be reduced while having predetermined heat resistance. The floor structure of the railcar includes a underframe having a pair of side sills extending in a railcar longitudinal direction and a cross beam arranged between the side sills and extending in a railcar width direction, a structural floor provided on an upper surface of the underframe, and a first heat insulating material arranged on a lower side of the structural floor via an air layer for the structural floor.

A crash energy absorber is provided at a front portion of a carbody of a railcar and configured to crush by a load from a front side to absorb crash energy. The crash energy absorber includes: a main absorbing portion extending in a front-rear direction; and a pair of sub absorbing portions respectively provided at upper and lower sides of the main absorbing portion. Each of the pair of sub absorbing portions is formed integrally with the main absorbing portion via breakable portions each extending in the front-rear direction.

An underframe structure of a railcar capable of reducing a deformation amount of a cross beam supporting an underfloor equipment upon underfloor fire. The underframe structure of the railcar includes an underframe having a pair of side sills extending in a railcar longitudinal direction and a cross beam arranged between the side sills and extending in a railcar width direction, a structural floor provided on an upper surface of the underframe, and an underfloor equipment suspended down in a center part in the railcar width direction of the cross beam. The underframe structure includes a passenger cabin floor provided on an upper side of the structural floor, the passenger cabin floor forming a lower surface of a passenger cabin S, and floor receiving members supporting the passenger cabin floor and extending in the railcar longitudinal direction between the structural floor and the passenger cabin floor.

An image processing apparatus includes a separating unit, a setting unit, and a determining unit. The separating unit separates an image into types of partial images other than a specific type, which is likely to be erroneously separated. The setting unit makes setting designating whether or not predetermined two types of partial images of the separated partial images are to be easily determined to be partial images of the specific type. The determining unit determines whether or not at least one of the predetermined two types of the partial images is the partial image of the specific type or not based upon the setting.
