Abstract:
The present invention provides a method which is capable of mainly detecting the objective substance by mass spectrometry and can also be applied effectively to a sample to be measured without conducting enrichment process. A mass spectrometric method comprising: in a mass spectrometry specifically ionizing a specific substance to be measured contained in a mixture sample containing the specific substance and a substance other than the specific substance by using a matrix that is more likely to ionize the specific substance than the substance other than the specific substance, to selectively measure the specific substance from the mixture. Preferably, the specific substance is a peptide modified with 2-nitrobenzenesulfenyl chloride, and the matrix is a nitrobenzene derivative such as hydroxynitrobenzoic acid. The matrix is preferably used in combination with α-cyano-4-hydroxycinnamic acid.
Abstract:
At least one basic precipitant selected from the group consisting of NaOH, KOH, NH4OH, NH3, NH4HCO3 and (NH4)2CO3 is added to an indium salt solution, which contains 0.1 to 3 M of indium, in an adding time of not longer than 24 hours, while the solution is maintained at a temperature of 5 to 95° C. until the equivalent of the basic precipitant reaches an equivalent of 0.5 to 3. Then, a precipitate obtained from the solution by a solid-liquid separation is dried and calcined at a temperature of 570 to 780° C. in an non-oxidizing atmosphere which contains ammonia gas and water vapor.

Abstract:
The invention provides sound insulation members having enhanced sound insulating properties without increasing the thickness of the sound insulation members. The object is achieved by a sound insulation member having disposed inside a pouch-shaped film 1 with a resin coating a flat sound absorption material 2 formed of foamed porous material or fiber material and having its inner space communicated, and filling a filler gas 3 having a sound impedance that differs from air. According to the present invention, since the present sound insulation member is filled with gas having sound impedance that differs from air, the present sound insulation member has superior sound insulating properties since it reflects sound on the sealed surface and also absorbs the sound by the sound absorption material disposed therein.

A liquid crystal layer 4 is formed such that the thickness thereof varies in accordance with transmission wavelengths of color layers 6, 7 and 8 so that a very good display which does not exhibit any coloring in whichever direction it is viewed may be obtained.An active matrix substrate A includes a plurality of opposing electrodes 2, a plurality of pixel electrodes 3 parallel to the opposing electrodes 2, a thin film transistor, and an orientation film 23 all formed on a glass substrate 10. A color filter substrate C includes an orientation film 56 provided on one surface of another glass substrate 10 and an optical compensation layer 35 provided on the other surface of the glass substrate 10 and formed from a plastic film. The two substrates are disposed such that the orientation films thereof oppose each other, and polarization plates 34 and 5 are disposed on the outer sides of the two substrates, and a liquid crystal layer 4 having a positive refractive index anisotropy is provided between the orientation films 23. The optical compensation layer 35 has a negative one axial refractive index anisotropy and can cancel a retardation produced in the liquid crystal layer 4 thereby to suppress white floating of a black display portion.

Abstract:
An active matrix liquid crystal display device includes a pair of substrates that seal a liquid crystal, thin film transistors, display pixel electrodes, m/s (s and m are natural numbers that render m/s a natural number) drain bus lines, s×n gate bus lines, and a controller. The thin film transistors are arranged on one of said substrates to form a matrix of n rows×m columns. The display pixel electrodes are connected to source electrodes of said thin film transistors in one-to-one correspondence. The drain bus lines are connected to drain electrodes of the matrix-type thin film transistors in s-to-1 correspondence. The gate bus lines are connected to gate electrodes of the thin film transistors on each row in one-to-one correspondence. The controller selects n gate bus lines in each of s frames starting from an (s×t(t is an arbitrary positive integer)+1)th frame and ended with an (s×t+s)th frame to perform one-screen display with the s frames. A method of manufacturing this display device, and a method of driving the same are also disclosed.
