Title: Power source device
Inventor: HATANAKA HIROSHI
IPC: G05F1/56
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To avoid the generation of an over-current at the time of starting a power source by outputting a prescribed control current based on a reference current from a reference current source which generates a reference current and from a reference voltage source which generates a reference voltage so as to output a driving current to a load and adjusting the control current of a current amplifier circuit based on an output voltage added to the load and the reference voltage. SOLUTION: When the output voltage Vreg is lower than a voltage prescribed by the reference voltage Vref, a base current is not supplied for the transistor Q6 of a first current amplifier circuit 12 to turn-off the transistor Q6 to amplify the reference current Iref by a prescribed amplitude to make a controlled current Icont. When the output voltage Vreg exceeds the reference voltage Vref, a control circuit 16 supplies a base current equivalent to a voltage difference for the transistor Q6 to reduce the base current of a transistor Q4 and the reduce-controlled base current is amplified by a prescribed amplitude to operate feedback control to fix the output voltage Vreg.

Abstract: PURPOSE:To improve the dependency of the angle of visual field by constituting transparent fine elements having reflecting walls on the peripheries in a plate shape so that the respective walls are arranged at an angle perpendicular to or nearly perpendicular to the plane of a side where light is projected. CONSTITUTION:The above screen is constituted in the plate shape as the integrated body of the transparent fine elements 3 having the reflecting walls 2 on the peripheries and the reflecting walls 2 of the respective elements are arranged at the angle perpendicular to or nearly perpendicular to the plate surface of the light projection side. Light made incident on a certain fine element advances in the fine element 3 by multiple reflection by the reflecting wall 2 on the periphery of the fine element 3. And most of it is made incident on the adjacent fine elements 3, so that it does not become stray light. By the alteration of the direction of every reflection and with the roughness of the reflecting wall 2, it has the large distribution of angle. Thus, the projected light becomes diffused light having the wide distribution of angle and shows excellent screen characteristic without depending on the angle of the incident light.

Title: Thermal transfer sheet
Inventor: MURATA YUKICHI
IPC: C09B57/08
Filed: 1987-01-31
Abstract: PURPOSE:To obtain a thermal transfer sheet with a coloring matter applied uniformly and at high density by adding a color material layer containing a specific quinophthalon coloring matter. CONSTITUTION:A color material layer containing a quinophthalon coloring matter expressed by the formula (I) is provided on a base film. When a coloring matter of the formula (1) is applied on a thermal transfer sheet, an ink is prepared by melting or dispersing in the form of fine particles a coloring matter into a medium with a binder. Then the ink is applied to a base film and dried to form a color material layer on the base film. Because of its presentation of a sharp yellow color, the quinophthalon coloring matter is suited to full color recording having satisfactory color reproducibility by combining magenta and cyan colors properly. Furthermore, the coloring matter sublimates easily and has a high coefficient of molecular light absorption. Therefore, it does not give a heavy load on a thermal head, thus obtaining a record of high color density at high speed.
