In a method of obtaining a color correcting condition for a color image on an image frame, plural color component image signals are obtained for each pixel of the color image of the frame, and the frame is divided into plural blocks each of which is composed of plural pixels. A block color density value statistic is obtained for each block from the plural color component signals of the plural pixels of each block, wherein the statistic indicates a relationship between a density value and a number of pixels indicating the density value. A chroma level of each block is evaluated based on the block color density value statistic; a frame color density value statistic is obtained from the plural color component signals of the plural pixels of the plural blocks of the frame by reducing an influence of a block evaluated as a high chroma block; and the color correcting condition for the color image is determined based on the frame color density statistic.

Idle frames are transmitted from first and second nodes of ring network in response to a first link failure, and protection switching is performed to form a first loop between the first and second nodes via at least a third node on receiving idle frames and Bridged & Switched frames are transmitted to the first loop. At the third node, AU (administrative unit) squelching is performed in response to a second link failure in the first loop, and protection switching is performed at the third node to form a second loop between the second and third nodes, and VT squelch is performed at the third node and busy indication frames are sent from the third node to the second node until the VT (virtual tributary) squelch is completed. From the third node to the second node, Bridged & Switched frames are transmitted and the AU squelch is cleared upon completion of the VT squelch. At the second node, AU squelching is performed in response to the busy indication frames from the third node, and AT squelch is cleared in response to the Bridged & Switched frames from the third node. Alternatively, the third node performs AU squelching in response to the second link failure and performs protection switching to form a second loop between the first and third nodes, and transmits Bridged & Switched frames to the first node. In response, the first node performs AU squelching, performs VT squelching and transmits busy indication frames to the third node until VT squelching is completed, and dears the AU squelch upon completion of the VT squelching. The third node responds to the Bridged & Switched frames from the first node for clearing the AU squelch.

A heterojunction semiconductor device has a plurality of ordered phase alloy layers. Either the whole or a part of each of the ordered phase alloy layers has a crystal structure (triple-period structure) in which the ordered alloy is of a composition corresponding to the [111]A direction and an anion composition modulation period that is triple that of a disordered structure. The double-period structure may alternatively be used. The triple-period or double-period structure applied to the layer structure of the heterostructure semiconductor device results in a reduction of the bandgap.

Crude immunoglobulin G isolated from human blood plasma is treated according to a conventional technique (such as the tricalcium phosphate adsorption method) to remove aggregates therefrom to such an extent that they are not detectable by gel filtration analysis. In order to produce an aqueous solution of immunoglobulin G having a reduced anticomplementary activity, the resulting solution is then filtered through a porous polyolefin membrane having a pore size larger than the molecular size of immunoglobulin G, in the presence of a stabilizer having surface activity. The aqueous solution of immunoglobulin G so produced is suitable for use in intravenous injection because its anticomplementary activity is low.
