Title: Optically functional film and its manufacture
Inventor: YOSHIHARA TOSHIO
IPC: G02B1/111
Filed: 1998-06-15
Abstract: PROBLEM TO BE SOLVED: To maintain a high function, high quality characteristics and productivity in an optically functional film and to put it into a practical use by forming a low refractive index layer directly or via other layer on a surface of a base material film, and forming the index layer as an SiO2 gel layer obtained by gelling an SiO2 sol having a molecular weight of a specific range. SOLUTION: A low refractive index layer 2 is formed on a surface of a base material film 1. An SiO2 gel layer is made of an SiO2 gel obtained by gelling an SiO2 sol having a molecular weight of 10,000 to 100,000 or preferably 20,000 to 50,000. When the molecular weight of the sol is smaller than this range, adhesive properties to the film is low and cannot be put into a practical use. When the molecular weight is larger than this range, an insoluble gel of a large quantity is generated, hence its solubility in a solvent is remarkably lowered and not preferable. Thus, the sol having the high molecular weight for improving the adhesive properties to the film while holding optical characteristics as they are can be sufficiently gelled at a temperature of the degree for not damaging the film.

Title: Digital output circuit
Inventor: YAMAMOTO MASAHARU
IPC: G09G3/12
Filed: 1990-06-26
Abstract: PURPOSE:To prevent a pulse noise from being induced in the output waveform of a segment terminal by making the time width of the output signal of a terminal other than the selected one the same time width, and in addition, making the time and the period of the rise and the fall of every output signal the same for every terminal. CONSTITUTION:The time width tD' of the high level of a digit terminal is made the same as the time width ts of the high level of the segment terminal. Namely, as for the output waveform S of the segment terminal, the period is T and the time width of the high level is ts. The periods and the time widths of the high level of the output waveforms D1, D2, D3 of the digit terminal are T and tD respectively, and at that time, the time widths are made ts=tD. Thus, at the time when the output waveform of the digit terminal in which an output current is large and impedance is low falls, if the output waveform of the segment terminal in which the output current is small and the impedance is high is made to fall simultaneously, the pulse noise is never induced in the segment terminal. Accordingly, the generation of the pulse noise of a high impedance side of the small output current can be suppressed.
