Patent JP-H0331884-A (JP)
Title: Copying preventing method
Inventor: OGAWA TOMOKO
IPC: G03G21/04
Filed: 1989-06-28
Abstract: PURPOSE:To prevent the leakage of confidential documents, etc., by sticking an irregularly reflecting material so as to trim a line which composes a character or a pattern. CONSTITUTION:When the line 3 which composes the character or the picture is formed on a base material 1, the irregularly reflecting material 2 is stuck so as to trim the line 3. When copying is performed, scanning beams 4 for copying abuts strongly on the material 2 which trims the line 3, irregularly reflected 5. Therefore, the quantity of light irregularly reflected by the material 2 increases as well, and the line 3 tends to be thinned. Thus, normally, the reflected light quantity 7 of a base part does not generate surface staining the reflected light quantity 6 of a line part which has a similar reflected light quantity, and hardly reproduces a line, thereby preventing a picture from being copied.

Title: Horizontal deflection circuit of color television receiver
Inventor: ARAKI YASUHIRO
IPC: H04N3/16
Filed: 1983-09-08
Abstract: PURPOSE:To drive a horizontal deflection circuit at a low voltage by turning on a horizontal output transistor (TR) just after the end of a blanking period of a horizontal output circuit to match a damper diode current and a current flowing to the horizontal output TR. CONSTITUTION:When a negative pulse is given from a flyback transformer 17 to a circuit 100, the pulse is differentiated by a capacitor 102 and a voltage is produced across a resistor 106. This voltage controls a TR101 via a resitor 108 for limiting a drive current of the TR101. When the TR101 is turned on, even if an output is given to a horizontal drive TR3 from a jungle IC1, the TR3 is not turned on. Then the on-period of the TR3 is changed by controlling the duty ratio of the horizontal oscillation drive output pulse outputted from the IC1 to change the on-period of a horizontal output TR7 thereby smoothing the connection of the collector current of the TR7 and the current of a diode 8.

IPC: H01S5/00
Filed: 1995-07-03
Abstract: PROBLEM TO BE SOLVED: To enable a surface light emitting semiconductor laser to be enhanced in degree of freedom of selection of semiconductor material which serves as the component elements of the semiconductor laser by a method wherein a semiconductor graded layer which changes gradually in composition is provided between a substrate and a layer or layers where lattice mismatching occurs between them. SOLUTION: When lattice mismatching occurs between a certain conductivity-type reflecting mirror layer 2 and a clad layer 3 and between a second clad layer 4 and an opposite conductivity-type reflecting mirror layer 7, a graded layer 8 is formed between the layers respectively, whereby the first clad layer 3 and the opposite conductivity-type reflecting mirror layer 7 are relieved of lattice mismatching, so that a semiconductor laser of this constitution is enhanced in laser characteristics. Or, one of the two layers is gradually changed in semiconductor composition in place of providing the graded layer 8 so as to gradually change the layers in lattice constant, whereby film characteristics can be prevented from deteriorating.  Furthermore, even a surface light emitting semiconductor laser equipped with a dielectric reflecting mirror layer composed of two dielectric layers of different refractive indexes can be enhanced in laser characteristics by employing this constitution.
