IPC: B41J2/175
Filed: 1989-12-22
Abstract: PURPOSE:To detect a residual ink amount with superior accuracy by an inexpensive device by a method wherein a pair of flexible electrode members can displace through an ink bag in accordance with a change in ink amount, and the pair of flexible electrode members in contact with each other are separated from each other by displacing, and vice versa.

The members 6A and 6B are respectively provided with electrode members 7A and 7B. When a sufficient amount of ink 8 exists in the ink bag 2, the electrode members 7A and 7B are separated from each other. Therefore, when an electric signal is applied to the electric connection part 6 for detecting an residual ink amount, the resistance of the ink 8 prevents an electric conduction. On the other hand, as the residual amount of the ink 8 is reduced, the electrode members 7A and 7B are deflected to come into contact with each other through a contact part 7C. Thus, the contact state is electrically fetched through the electric connection part 6, whereby the exhaustion of the ink 8 is detected.

Filed: 1989-12-20
Abstract: PURPOSE:To automatically set an optimal threshold voltage under any condition by providing pieces of D-type FFs, setting the upper limit and the lower limit of a threshold level by two pieces, and setting an average value as a threshold level of the remaining one piece. CONSTITUTION:In the beginning, the output voltage of a threshold generating circuit THG 9, and an output of a THG 10 are set to the upper limit and the lower limit, respectively. In this case, in a D-type F/F 3, since a threshold voltage is high, an error is generated at the time when an input signal is '1', and in an F/F 4, an error is generated at the time of '0' due to a low threshold. Accordingly, a signal is generated in an EX-OR 6. These signals are compared by a comparing circuit CMP through an integrator 7, and in accordance with whether the value is large or small, the output of the THG 9 and the output of the THG 10 are varied to become smaller and larger, respectively. As a result, the F/F 3 and 4 do not generate an error, respectively, and when there is no error, an output of the EX-OR 6 becomes '0'. In this case, the outputs of the THGs 9, 10 are averaged by an average value circuit AV, and given to an F/F 5 as an optimal threshold voltage.

Title: Absorption structure to mask and disperse liquid
IPC: A61F13/15
Filed: 1992-12-14
Abstract: PURPOSE: To make liquid absorbed and transmitted and to cover an area to transmit liquid in maximum so as not to be visible from a wearer, by making an absorption structure be a structure with an upper nonwoven masking layer and a lower nonwoven dispersing layer. CONSTITUTION: This absorption structure is equipped with a nonwoven masking layer and a nonwoven dispersing layer.
