摘要:
A motion vector search unit determines a unit area of a bidirectional prediction frame for each motion vector of a backward reference frame to pass through, and stores information on the unit area to be passed into a pass area number holding unit. A reference vector prediction unit consults the pass area number holding unit to acquire the motion vector of the backward reference frame that passes a target unit area of the bidirectional prediction frame from a motion vector holding unit, and determines a reference vector to be applied to this target unit area. The motion vector search unit applies the reference vector to the target unit area of the bidirectional prediction frame, determines a forward motion vector and a backward motion vector of the target unit area by linear prediction, and makes a motion compensated prediction on the target unit area bidirectionally to generate a predicted image.

A local motion vector detection unit 66 obtains a local motion vector LMV for each macro block in a coding target frame image. A region setting unit 64 sets multiple global regions in the frame image. A global motion vector calculation unit 68 calculates a global motion vector GMV which indicates the global motion within each global region. A local motion vector difference coding unit 72 performs coding of the difference ΔLMV which has been obtained by making the difference between each of the local motion vectors LMV within the global region and the global motion vector GMV obtained for each global region. A global motion vector difference coding unit 74 performs coding of the difference ΔGMV which has been obtained by making the difference between each of the global motion vectors GMV obtained for corresponding global region and the reference global motion vector GMVB serving as a reference.

A motion vector detecting unit 24 detects a motion vector between an input image and a reference image. A reduced image creation unit 40 reads out pixel data of the reference image from the frame memory, and creates a reduced image at a lower resolution than that of the original reference image. A reduced image holding unit 42 stores a part or all of the reduced image thus created. A computation unit 44 performs matching computation between the input image and the reference image using the reduced images, thereby detecting an approximate motion vector. Subsequently, the computation unit 44 detects a motion vector using the images at the original resolution with reference to the approximate motion vector. When the computation unit 44 detects the motion vector using the reduced images, a part of the reduced image stored in the reduced image holding unit 42 is not newly created, and is read out from the reduced image holding unit 42.

An electrical contact for attachment to an insulated wire includes an insulator crimp section (11) having a pair of insulation engaging arms (12a, 12b) which are offset from each in an axial direction of the wire. The insulation engaging arms include facing edges (38a, 38b) which are arranged to contact each other along a spiral track when the insulation engaging arms are press-bonded to the insulation of the wire. Inside beveled surfaces (18a, 18b) and outside beveled surfaces (28a, 28b) serve to guide the insulation engaging arms into position and to facilitate sliding contact between the facing edges (38a, 38b) during the press-bonding. The inside beveled surfaces (18a, 18b) also provide a gap (4B) which serves as a relief area for compressed insulation. As a result of the press-bonding, the insulation engaging arms (12a, 12b) are formed into an integral unit and are strongly fastened to the insulation of the electrical wire.

The electrical connector of the present invention is equipped with contacts that are secured in a housing. The contacts are formed to have a pair of spring members surrounding a contact receiving opening. The housing has contact receiving cavities for accommodating each contact. Each contact receiving cavity is contoured to have a base wall, a mating contact receiving opening passing through the base wall and a rail projecting from the base wall, the rail extending along the base wall on opposite sides of the mating contact receiving opening. During contact insertion the spring members grip the rail to angularly orient the contact within the contact receiving cavity.
摘要:
A cellulose acetate membrane composed of a mixture comprising a cellulose triacetate and a cellulose diacetate and having an improved heat stability, which does not substantially show a melting peak of cellulose diacetate but substantially shows a melting peak of cellulose triacetate, in a differential thermal analysis. By mixing a cellulose triacetate and a cellulose diacetate at an appropriate ratio, crystallization or orientational crystallization of each component due to a high pressure stream sterilization can be avoided and a cellulose acetate membrane with improved water permeability and sieving coefficient of myoglobin after a high pressure steam sterilization can be obtained.

Isotropic tool steel consisting essentially of necessary elements as tool steel, less than 0.005 weight % of S and less than 30 ppm of O, the balance being substantially Fe. The necessary elements are, by weight, 0.10-0.70% of C, 2.00% or less of Si, 2.00% or less of Mn, 7.00% or less of Cr, 0.20-12.00% of W and/or Mo alone or in combination (1/2W+Mo), 3.00% or less of V. They may further include at least one of 4.00% or less of Ni, 6.50% or less of Co and 0.20% or less of N. The isotropic tool steel has cleanliness with respect to non-metallic inclusions defined by JIS G 0555 of dA60.times.400.ltoreq.0.010% and d(B+C)60.times.400.ltoreq.0.020%, and a ratio of transverse direction toughness to longitudinal direction toughness of more than 0.70. Since it is highly resistant to the generation and propagation of cracks and fracture, dies for hot working made therefrom can enjoy a long life.
