Backlight device

PROBLEM TO BE SOLVED: To provide a backlight device capable of easily checking whether set optical sheets are removed or not, and checking an order of lamination. SOLUTION: The backlight device comprises a support plate, a light guide plate 30 arranged on a front surface side of the support plate and emitting light from a light source introduced from an end surface to a front surface, a first optical sheet 40, a second optical sheet 30, and a third optical sheet 51 sequentially laminated on a front surface side of the light guide plate 30. The third optical sheet 51 includes a window part 52 on a lower end. In a laminated state of the first optical sheet 40, the second optical sheet 50, and the third optical sheet 51 in this order, a part of the first optical sheet 40 appears from the window part 52, and a part of the second optical sheet 50 appears from the window part 52 while covering the first optical sheet 40. A shape of the part of the first optical sheet 40 and a shape of the part of the second optical sheet 50 are different. COPYRIGHT: (C)2009,JPOandINPIT

Process for the manufacture of 7β-amino-3-cephem-3-ol-4 carboxylic acid compounds

7β-amino-3-cephem-3-ol-4-carboxylic acid compounds of the formula STR1 wherein R1a represents hydrogen or an amino protective group R1A and R1B represents hydrogen or an acyl group Ac, or R1a and R1b together represent a bivalent amino protective group, R2 represents hydroxyl or a radical R2A which together with the carbonyl grouping --C(=O)-- forms a protected carboxyl group and R3 represents hydrogen, lower alkyl or a hydroxyl protective group, and 1-oxides or 3-cephem compounds of the formula IA, and the corresponding 2-cephem compounds are prepared in that a compound of the formula STR2 wherein R1a, R1b and R2A have the meanings mentioned under formula IA, R3o represents lower alkyl or a hydroxyl protective group and Y represents a group which is removed, is treated with a base; also comprised are intermediate products.
