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:
A process for producing an ethylene copolymer which comprises polymerizing a predominant amount of ethylene and a minor amount of an alpha-olefin having 4 to 10 carbon atoms in the gaseous phase in the presence of a catalyst composed of (A) a transition metal catalyst component and (B) an organometallic compound of a metal of Groups I to III of the periodic table; characterized in that the copolymerization is carried out under the following conditions (i) and (ii),(i) at least 1 mole, per mole of ethylene, of a gaseous saturated hydrocarbon having 3 to 6 carbon atoms is caused to be present in the gaseous phase copolymerization system, and(ii) the gaseous mixture containing the unreacted olefin which has been discharged from the gaseous phase copolymerization system is cooled to a temperature at which the mixture is not liquefied, and the cooled gaseous mixture is recycled to the gaseous phase copolymerization system.
摘要:
A round-off type of numeric data display apparatus which has at least X, Y, Z and K registers, and which stores in said X register a previous data item obtained by a previous one of arithmetic operations convergently producing a result in turn, stores in said Y register an immediately succeeding data item obtained by an immediately succeeding one to said previous one of said arithmetic operations, stores in said K register that number of digit-place data items to be rounded-off of said immediately succeeding data item which has been obtained by the arithmetic operation in an arithmetic-operational section connected to said X, Y, Z and K registers, subjects said immediately succeeding data item to rounding-off operation in said arithmetic-operational section on the basis of the contents item of said K register and stores the result of said rounding-off operation in said Z register, transfers the contents item of said Z register and a decimal point code of said Y register to a display buffer connected to said Y and Z registers, and displays only numeric data of reliable digit-place number from a display section connected to said display buffer.
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.
