Abstract:
A single cell-culture chamber is provided that includes a dried vitrigel membrane covering and secured to one open end surface of a tubular frame. Also provided is a double cell-culture chamber that includes two tubular frames of substantially the same planar cross-sectional shape adhesively secured to each other with a dried vitrigel membrane interposed between the opposing open end surfaces of the tubular frames so as to form a first chamber and a second chamber via the dried vitrigel membrane.
Abstract:
The present invention provides a non-aqueous electrolyte solution that can be used as an electrolyte solution of a non-aqueous secondary battery to improve the discharge rate performance of the battery. The non-aqueous electrolyte solution comprises a non-aqueous solvent and a BF3-cyclic ether complex. The BF3-cyclic ether complex content is greater than zero part by mass, but less than 1 part by mass relative to 100 parts by mass of the total amount of other electrolyte solution components. Preferable examples of the BF3-cyclic ether complex include BF3-tetrahydropyran complex and BF3-dioxane complex.
Abstract:
A dried vitrigel membrane is produced by a method including the following steps of (1) a step of keeping a hydrogel in the inside of a wall surface mold with a shape the same as the desired shape disposed on a substrate, and discharging a part of free water within the hydrogel from a gap between the substrate and the wall surface mold; (2) a step of removing the wall surface mold from the top of the substrate; (3) a step of drying the hydrogel to remove the residual free water, thereby fabricating a vitrified dried hydrogel; (4) a step of rehydrating the dried hydrogel to fabricate a vitrigel membrane; and (5) a step of redrying the vitrigel membrane to remove free water, thereby fabricating a vitrified dried vitrigel membrane.

Abstract:
A variable-length encoder that feeds a Coded Block Pattern (CBP) as an input symbol to variable-length code output part. Coded symbol memory supplies CBPs in neighboring blocks as coding map table reference information to coding map table provider. Coding map table provider determines a coding map table used in coding of the CBP, based on these CBPs in the neighboring blocks, and provides a coding map table H4 to variable-length code output part. Variable-length coding table provider feeds a variable-length coding table to variable-length code output part. Then the coding target CBP is subjected to variable-length coding, and the resultant is outputted as coded data. This allows information source coding of coding symbols to be performed efficiently according to the coding condition and the property of image.
Abstract:
The invention provides an information recording medium including highly reliable power calibration areas, as well as an information recording and reproducing device utilizing it. The medium is an information recording medium having a recording layer including a data recordable area 50 for recording user information signals, a lead-in area provided on the inner periphery of the data recordable area 50, an inner power calibration area provided further on the inside of the lead-in area for recording test recording patterns, and a recording management area for recording management information related to the inner power calibration area. An outer power calibration area 70 is provided on the outer periphery of the final point of recording of the user information signal on the recording layer.
Abstract:
Provided is a contact lens of double thin type ensuring a comfortable wearing sensation, enabling improvement of oxygen permeability and tear exchange, and having a novel structure. An optical zone having no deviation of a center of gravity by a prism is formed. A pair of thin portions extending circumferentially and having a constant thickness are formed on both upper and lower sides of a peripheral zone, and a pair of thick portions extending circumferentially and having a thickness larger than that of the thin portions are formed on both left and right sides. One or more concavities are positioned symmetrically in a left-right direction during wear in a posterior surface of each of the thick portions. A minimum thickness at a portion where the concavity is formed is larger than the thickness of the thin portions.
Abstract:
A battery capable of improving the storage characteristics and the cycle characteristics is provided. The battery includes a cathode, an anode, and an electrolytic solution. The electrolytic solution is impregnated in a separator provided between the cathode and the anode. A solvent of the electrolytic solution contains a given sulfone compound such as bis(trimethylsilyl)-2,2-difluorosulfoacetate. Compared to a case that a solvent does not contain the foregoing sulfone compound, the chemical stability of the electrolytic solution is improved, and the decomposition reaction of the electrolytic solution is suppressed.
