Abstract: PURPOSE:To attain efficient data compression in which deterioration in picture quality is suppressed, by dividing a two-dimensionally arranged data block into prescribed shaped unit blocks, and setting the number of encoding bits independently at every block. CONSTITUTION:A picture data inputted from the outside is written in double buffers 10a and 10b alternately by every unit block arranged two-dimensionally consisting of picture elements of 16X16, and hereafter, an encoding processing is applied on every block. Data read out from the double buffer 10, after being cosine-transformed, are stored alternately in double buffers 12a and 12b, and weighing processing are applied on them at a weighing instrument 14. Weighed data are inputted to an integer instrument 15 at the next stage, and after the decimal point parts of them are deleted, they are added on a re-quantizer 16.

IPC: F28D19/04
Filed: 1987-08-28
Abstract: PURPOSE:To make it possible to surely seal the outer circumference of a rotor by a method wherein a sealing surface molding instrument is pressed, at a fixed position, against the protrusion of a resin material protruded out of the surface of the rotor and the height of the sealing surface to be formed is made even so as to be slidably contacted with a sealing material. CONSTITUTION:After a rotor 1 is housed and disposed within a casing 3, a foaming filler 7 which acts as an anchor material is filled into the surface portion of the rotor 1 along the periphery of the rotor 1, with which a sealing material 4 is slidably contacted, and a resin material 8 is pushed in on top of said filler 7 to be filled so as to take a state wherein the resin material 8 is partly protruded out of the surface of the rotor 1. Thus, while rotating the rotor 1, a sealing surface molding instrument 9 such as a lancet or a trowel is pressed, at a fixed position, against a protrusion 8a, and the height of a sealing surface S is made even so as to be slidably contacted with the sealing material 4. Accordingly to this method, even when the surface of the rotor 1 is uneven, such unevenness is absorbed by providing the protrusion 8a of the resin material 8 filled into the surface portion of the rotor 1, and the sealing surface S formed on the protrusion 8a is leveled off so as to be in a flush state. Accordingly, the outer circumference of the rotor 1 may be reliably sealed by an extremely simple process.
