摘要:
A carrier for cell culture is provided which improves the cell proliferativity in serum-free culture and which is free from risk from infection factor contamination. The gist of the features of the present invention is to be formed of a crosslinked poly(meth)acrylic acid (salt) particle (A) and an artificial polypeptide (P) having at least one cell-adhesive minimal amino acid sequence (X) in one molecule and to have a water retention value of from 2 to 50 g/g. The (A) is preferably a particle produced by reversed phase suspension polymerization of an aqueous monomer solution containing (meth)acrylic acid and/or an alkali metal salt of (meth)acrylic acid. The (P) preferably has at least one auxiliary amino acid sequence (Y) in one molecule of the (P). The (X) is preferably an Arg Gly Asp sequence.

The present invention provides a process for producing 2,3,3,3-tetrafluoropropene including the step of dehydrofluorinating 1,1,1,2,3-pentafluoropropane, wherein 1,3,3,3-tetrafluoropropene and 1,1,3,3,3-pentafluoropropane are supplied together with 1,1,1,2,3-pentafluoropropane to a reactor containing a catalyst to simultaneously perform dehydrofluorination reaction and isomerization reaction. According to the process of the present invention, 2,3,3,3-tetrafluoropropene (HFO-1234yf) can be efficiently produced by effectively using the by-products of the dehydrofluorination reaction.
摘要:
A noise reducing device captures image data obtained by capturing a field with an image capturing part and a plurality of blackout image data obtained by capturing the field with the image capturing part under a light shielded state. This device reduces non-correlative random noise in the plural blackout image data. With random noise reduced, fixed pattern noise appears more accurately in resultant as blackout image data B. This device reduces the fixed pattern noise in the image data by using this blackout image data B.

An optical pickup includes a first objective lens, a second objective lens having a numerical aperture different from that of the first objective lens, and an objective lens holder that holds the objective lenses. The first objective lens is attached to the objective lens holder via a spacer. The objective lens holder has a first fixture hole that receives the spacer with the first objective lens and a second fixture hole that receives the second objective lens. The first fixture hole is provided with a spacer supporting portion in which the spacer is inserted in a rotatable manner.

An imaging device has an image pickup section, a compression processing section, a correlation data holding section, and first and second calculating sections. The image pickup section generates photographic image data. The compression processing section performs compression processing on photographic image data. The correlation data holding section holds plural correlation data on changes in scale factor and compressed data amount of sample image data. The first calculating section calculates initial scale factors from standard correlation data generated from image data including high-frequency components most among sample image data and target compressed data amount. The second calculating section determines whether recompression processing by use of a different scale factor is necessary from a difference between target compressed data amount and compressed photographic image data amount and calculates the scale factor based on compressed photographic image data and correlation data at recompression processing such that the data compression rate decreases.
