    摘要: Considering the differential pressure .DELTA.P between pressures applied to both faces of a meniscus formation member, the differential pressure .DELTA.P becomes the maximum when an ink supply unit is left standing with the meniscus formation member placed upward. At this time, water head PH of ink attempting to fall due to gravity is applied to the inner face of the meniscus formation member in the same direction as negative pressure PR of a capillary member. Thus, the differential pressure .DELTA.P becomes .DELTA.P=PR+PH. The bubble point pressure PB of the meniscus formation member is set greater than the maximum value of the differential pressure, .DELTA.P=PR+PH, whereby air does not enter an ink tank through the meniscus formation member.

    摘要: An electronic watch including a watch circuit and display is provided which additionally includes an automatic time indication modifier. The modifier comprises a receiver, a filter for passing only that component of the signal from the receiver which has the same frequency as a time announcement signal, a pulse height discriminator for converting an output signal of the filter into a bi-level signal in accordance with the magnitude of the output signal above a threshold level, a time announcement pattern discrimination circuit responsive to the bi-level signal from the discriminator to determine the presence of a time announcement pattern on the basis of the duration of and the time interval between the bi-level signals, and a "seconds" indication modifying and control circuit for modifying a "seconds" indication of the watch in response to an output signal from the discrimination circuit.
