An image area discriminating method surely distinguishes a character image area and a halftone image area printed on a single document in response to image data outputted by an image reader. An image of interest is divided into N.times.N blocks and subjected to two-dimensional orthogonal transform block by block to produce an N.times.N coefficient pattern. The blocks each is compared with coefficient patterns prepared beforehand and matching the characteristics of character images to see if the block lies in a character image area or in a halftone image area. The N.times.N coefficients may be replaced with N.times.N vectors. Then, a necessary number of vectors are selected out of the N.times.N vectors to generate a .upsilon.-dimensional coefficient vector, and it is compared with vecotrs prepared beforehand for character identification and matching the characteristics of character images.

A method applicable to an image filing system or similar system for recording data representative of a halftone image by compressing the data and reconstructing the compressed data. In an input two-dimensional halftone image, the coordinates points where a difference of density changes in the x direction are determined to produce an x direction transition point pattern associated with the coordinates. A y direction transition point pattern is produced by effecting similar processing in the y direction. Further, an AND pattern of the x direction and y direction transition point patterns is generated. The pixels based on the AND pattern are determined to be the characteristic density and are coded, the densities of the other pixels being calculated at the time of decoding. The transition patterns are individually coded by transforming the differences of density data into Huffman codes.

The invention has for its object to provide a heat-shrinkable laminated film for deep drawing, which has an increased carbon dioxide transmission rate (CO2TR) and an enhanced ratio (CO2TR/O2TR) of carbon dioxide transmission rate-to-oxygen transmission rate (O2TR), and is less susceptible to pinholes. In the inventive heat-shrinkable laminated film for deep drawing, a polyamide resin composition layer (a) containing a polyamide resin mixture comprising 60 to 95% by mass of an aliphatic polyamide resin (A) and 5 to 40% by mass of a polyamide base resin (B) having a heat of crystalline fusion of 5 to 40 J/g is laminated onto a heat-sealing resin layer (a) containing a polyolefin resin via an adhesive resin layer (b).

Included are a testing step (S1) for determining the relation between the shear stress amplitude of a rolling contact metallic material and the number of loading by means of an ultrasonic torsional fatigue test, and a shear fatigue strength determining step (S2) for determining the shear fatigue strength τlim, within the ultra long life regime from the relation between the shear stress amplitude and the number of loadings, which relation has been determined during the test step (S1), in accordance with a predetermined standard. It is a completely reversed torsional fatigue test, in which torsional vibrations, respective torsions in the positive rotational direction and reversed rotational direction of which are symmetrical relative to each other, are applied to a test piece (1).
