摘要:
An abrasive type vertical grain milling machine comprises a perforated cylindrical body which serves to define an outer periphery of a grain milling chamber and which has a plurality of vertically arranged resistance members projected radially into the grain milling chamber so as to impart resistances to motions of the grains in a circumferential direction of an abrasive type roll assembly, an amount of projections of each of the resistance members being made to be adjustable, and further has projection amount adjusting mechanisms for adjusting independently the respective amounts of projection in the radial direction of the plural resistance members located in different vertical positions, and therefore, it is possible to adjust independently the resistance imparted to the motions of the grains within the grain milling chamber in each of the upstream-side region and downstream-side region of the grain milling chamber.

An abrasive type vertical grain milling machine comprises a perforated cylindrical body having at least one perforated arcuate plate member which is formed therein with both a first group of elongated bran-removing holes serving to lead grain to be milled in a direction from an inlet side toward an outlet side of a grain milling chamber when the grain is rotated in the direction of rotation of a grain milling roll assembly within the grain milling chamber and a second group of elongated bran-removing holes serving to lead the grain to be milled in a direction from the outlet side toward the inlet side of the grain milling chamber when the grain is rotated in the direction of rotation of the grain milling roll assembly within the grain milling chamber, and therefore, grain can be milled highly efficiently and the progress of breakage of grains caused at the time of grain milling can be suppressed.

There is disclosed an abrasive type vertical grain milling machine in which a space formed between any two adjacent ones of abrasive rolls serves as a jet air groove. The space serving as the jet air groove is of such an axial size that grain to be milled can come into and out of the space. Preferably, an axial thickness of the abrasive roll is 1.5.about.4 times larger than an axial magnitude of the space.

Substantially all of the laser light emitted from laser chip(s) 11 toward optical disk(s) 17 may be transmitted through polarizing hologram(s) 13 and may thereafter be transmitted through quarter-wave plate(s) 15, and after being reflected at optical disk(s) 17, may again be transmitted through quarter-wave plate(s) 15 and be incident on polarizing hologram(s) 13. Accordingly, where laser light is transmitted twice through quarter-wave plate(s) 15, the direction(s) of polarization thereof may be rotated by 90 degrees before it is incident on polarizing hologram(s) 13. For this reason, even if laser light is p-polarized when it is transmitted through polarizing hologram(s) 13 from laser chip(s) 11, it may be s-polarized when it is again transmitted through polarizing hologram(s) 13 after being reflected from optical disk(s) 17. Laser light, after being made s-polarized, may be diffracted by polarizing hologram(s) 13, which diffracts only s-polarized light. Light of order ±1 produced as a result of diffraction of laser light by polarizing hologram(s) 13 may be incident on photodiode(s) 18.

Herein described are a motion estimation method and a motion estimation apparatus for calculating a motion vector to estimate a current picture based on a reference picture. The current picture is partially formed by a current block represented by pel values. The reference picture is partially formed by a search window represented by pel values and having a plurality of candidate blocks. There are provided processor elements and side register units arranged in the form of a matrix array. The pel values of the search window are fed to the processor elements and the side register units. The pel values of the current block are fed to the processor elements. Between the processor elements and the side register units, are shifted pel values of the search window. The processor elements are designed to calculate distortion values each indicative of a difference between the current block and each of the candidate blocks on the basis of the received pel values of the search window and the received pel values of the current block. The method and apparatus are characterized in that, at one of the adjoining two columns of the matrix array, the pel values of the search window are shifted only in an upward direction, while, at the other of the adjoining two columns of the matrix array, the pel values of the search window are shifted only in a downward direction.
