Title: Production of chitin derivative
Inventor: KAMITSURA MASAYOSHI
IPC: C08B37/08
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To selectively and efficiently effect, e.g. the reaction of forming N- phthaloyl by allowing N-deacetylated chitin and an acid anhydride to initiate reaction under acidic conditions and then to continue the reaction under basic conditions after some time on the way to thereby form a chitin derivative. SOLUTION: N-deacetylated chitin is dissolved in a methanol/water mixture, and the pH of the solution is adjusted to 5.5 or lower by adding acetic acid or the like. An acid anhydride represented by, e.g. formula I, such as phthalic anhydride, is added to the solution to initiate reaction at 20-80 deg.C. After some time on the way, sodium carbonate or the like is added to render the solution basic with a pH of 8.5 or higher so that the amino groups of the N-deacetylated chitin is acylated to give a chitin derivative represented by, e.g. formula II. The chitin derivative is made to effect ring closure at 150-300 deg.C to give a chitin derivative represented by, e.g. formula III. The N-deacetylated chitin is obtained by deacetylating the N-acetyl groups in the N-acetylglucosamine residue of chitin. In the formulas, X is a monovalent group except for H; and n is an integer of 1 to 10.

Filed: 1996-04-10
Abstract: PROBLEM TO BE SOLVED: To make it possible to deal with a trend toward a wider visual field angle by relieving the luminance difference in the intra-surface direction of substrates. SOLUTION: The liquid crystal display device of an MIM diode system is constituted by elevating the on current of the MIN diode existing on a bright viewing side 101 (for example, on the 12 o'clock side of a watch) in the intra- surface direction of the substrates 10 and lowering the on current of the MIN diode existing on a reverse bright viewing side 102 (for example, 6 o'clock side of a watch). The angle θ2, θ3 formed by the liquid crystal molecules 32 existing on both of the bright viewing side 101 and the reverse bright viewing side 102 and visual lines L2, L3 are, therefore, approximated to the angle θ1 formed by the visual line L1 on the normal and the liquid crystal molecules 32 and the luminance difference is relieved.

Title: Light radiating device
Inventor: KAWASUMI KENICHI
IPC: H05B41/16
Filed: 1988-04-13
Abstract: PURPOSE:To make it possible to make a light emission strength constant while operation and make a light acting period constant without increasing the cost of a lighting circuit of a light source by making the light emission strength constant by controlling the steam pressure of light emitting material. CONSTITUTION:For a light source 1 having inactive gas and light emitting material enclosed, its light emission strength decreases gradually while operation. For the decrease of light emission strength while operation, the steam pressure is increased gradually corresponding to decrease of the light emission strength while operation so as to make the light emission strength constant while operation by using the change of light emission strength by change of the steam pressure of the light emitting material until the steam pressure is increased up to a steam pressure corresponding to the maximum light emission strength by the steam pressure of the light source. The light emission strength can thus be constant while operation, and an acting time using the light wavelength effect can be constant during the life of the light source 1.

Title: Isdn terminal equipment
Inventor: UEJIMA YOSHIYUKI
IPC: H04M11/00
Filed: 1991-03-29
Abstract: PURPOSE:To prevent a TEI from being double registered at the plural ISDN terminal equipments. CONSTITUTION:An ISDN terminal equipment 13 is equipped with a ROM 14, and this ROM stores random number initial values peculiar for the respective terminal equipments. When the terminal equipment is started, a CPU 13b applies the random number initial value to a random number generation part 13d as a random number generating command. While responding to the random number generating command, the random number generation part 13d applies a random number to an ISDN exchange 11 as a TEI allocating request. Since each terminal equipment generates the random number based on the random number initial value, the TEI can be prevented from being double registered.
