Abstract: The outdoor display system has a solar cell; an electricity storing unit which stores electricity obtained by the solar cell, and a display apparatus having a displaying portion displaying contents, wherein the apparatus is supplied an electric power from the storing unit or solar cell. The display apparatus may contain a display panel which displays contents; a receiving unit which receives contents transmitted wireless; a backlight which irradiates light to the display panel, and a control unit which controls the displaying of the received contents in the display panel. The control unit may perform the luminosity control of the backlight according to a residual capacity of the electricity storing unit.

Abstract: A display system has a solar cell; a battery unit storing an electric power; a display apparatus which displays image; a controller which controls the power supply of the electricity generated by the solar cell to the display apparatus and the battery unit, the controller further controls the power supply from the battery unit to the display apparatus, and a receiving unit which receives a weather information, wherein the controller controls the percentage among the power supplying to the display apparatus and the battery unit according to the weather information received by the receiving unit.

Abstract: The outdoor display system has a solar cell; electricity storing device which stores electric power; a display apparatus which displays information, and a control device which supplies the electric power obtained by the solar cell to the display apparatus or the electricity storing unit. The control device has an acquisition part which acquires weather forecast information, and an accommodating adjusting part which accommodates adjusts the ratio of the electric power supplying to the display apparatus or to the electric power storing to the electricity storing unit according to the weather forecast information acquired by the acquisition part.

Abstract: A method of refilling an ink bag that is used in an ink jet recorder, the ink bag is initially filled with ink through an opening in the bag, and is sealed after the ink bag is initially filled. The method comprises the steps of removing the ink bag from the ink jet recorder, positioning the ink bag, inserting an ink needle into a separate opening in the ink bag that is different than the first opening through which the ink bag is initially filled with ink, discharging ink from the ink bag through the second opening, and charging the ink bag through the second opening with a specified quantity of ink.

Abstract: A hydrotalcite-type compound [M2+1−xM3+x(OH)2]x+[An−x/nmH2O]x− (where M2+ is a bivalent metal ion, M3+ is a trivalent metal ion, An− is an anion of valency n and 0<x≦0.33) is mixed with a binder such as colloidal silica to obtain a film-forming composition. The film-forming composition can form strong coatings that exhibit hydrophilic properties. The hydrotalcite-type compound can disperse in water under acidic conditions, thus allowing its mixture with the binder. Once the hydrotalcite-type compound is dispersed with the acid, it can then be diluted with water or an alcohol. This makes it possible to obtain coatings containing titanium oxide, etc., that constantly exhibit hydrophilic properties with or without light irradiation.

Abstract: A method of manufacturing an ink cartridge for use in an ink jet recorder, comprising the step of providing an ink bag having a top end, and a bottom end below the top end, the top end being open and the bottom end having an ink feed port therein; moving the ink bag from a first position near a top edge thereof and positioning the ink bag in a vacuum chamber; depressurizing the vacuum chamber; charging a selected quantity of ink into the ink bag; sealing the open end of the ink bag at a second position below the first position; pressing the sealed portion of the ink bag to a selected thickness with press plates; sealing the bag in the pressed position at a third position below the second position; and cutting the ink bag between the second and third positions.

Abstract: A method of refilling an ink bag of an ink cartridge for use in an ink-jet recorder. The method includes first removing the ink cartridge and ink bag from the ink-jet recorder. The ink bag may then be refilled by positioning the ink bag on a surface, inserting an ink needle into a port of the ink bag, and by discharging ink from the ink bag and charging the ink bag with a specified quantity of ink.
