    Abstract: The battery pack (1) is connected to an external device (9) and to a power supply circuit (10) for the external device (9), and it energizes the external device (9) or is charged by the power supply circuit (10). Communication is made between a microcomputer (11) inside the battery pack (1) and the external device (9) through terminals (8) and at least information representing a present residual charge of a battery (4) is transmitted from the microcomputer (11) to the external device (9). This residual charge is calculated by the microcomputer (11) using the current, voltage, internal resistance and temperature of the battery (4). In this way, the residual charge can be obtained with a high level of accuracy on the side of the external device (9).

    Abstract: The present invention is to provide an on-demand type ink-jet printer which is free from the risk such that the nozzle is stopped and which is also free from the maintenance. An ink-jet print head comprises a liquid chamber (2) into which a carrier liquid (7) is filled, ink-jet driving means (3), (4) disposed within the liquid chamber (2), a nozzle (14) communicated with the liquid chamber (2) and a mixing unit (14a) disposed in the vicinity of the nozzle (14) for mixing an ink (9) into the carrier liquid (7). The ink (9) is mixed into the carrier liquid (7) in the liquid chamber (2) by the mixing unit (14a), pressed by the ink-jet driving means (3), (4) and then ink-jetted from the nozzle (14). Since the carrier liquid (7) is constantly filled into the nozzle (14), the nozzle (14) can be prevented from being choked up.

    Abstract: A coordinate position digitizing system incorporates apparatus for detecting the X and Y positions of a voltage detecting device relative to a position determining plate employing apparatus for generating data corresponding to the X and Y positions of said voltage detecting device on said plate at successive sampling times, means for calculating the difference corresponding to the difference in the indicated position at two successive sampling periods, and rejecting signals indicating positions which differ from previous positions by distances which are greater than a predetermined amount, corresponding to the maximum distance that the voltage detecting device can be moved between successive sampling periods. In this way, position-indicating signals which are corrupted by noise pulses or the like are rejected.

    Abstract: PURPOSE:To carry out the intermediate tone printing having the uniformity of image by a method wherein an ink ejection nozzle ejecting an ink and a transparent solvent ejection nozzle ejecting a transparent solvent are closely located and the ink and the transparent solvent are mixed outside of the nozzles. CONSTITUTION:On the starting of the printing, a pulse type do voltage is applied on opposing mesh electrodes provided on the each surface of an electric permeation membrane 16 of an ink reservoir section 5 to supply a specified amount of ink 4 from an ink supplying passage 7 to an ink ejection nozzle 13 of a mixture nozzle section 8 so that the ink is not ejected from an ink nozzle 15 to stay at an outlet with being a ball shape. Next, a specified voltage is applied on opposing electrodes 11a of an electrostrictive vibrator 11 to reduce a volume of an ink reservoir 3 by the distortion of the electrostrictive vibrator 11 so that a transparent solvent 2 is ejected from a transparent solvent nozzle 14. At that time, the ink ball is influenced by the movement of the transparent solvent 2 and they are unified with each other to form a mixture liquid which is ejected from a mixture nozzle section 8 and spouts. The pressure applied on the ink reservoir 3 is effectively transferred to the mixture nozzle section 8 without hindering a transparent solvent supply passage 6 by means of a one way valve 9 disposed therein.
