Filed: 1997-09-26
Abstract: PROBLEM TO BE SOLVED: To provide an ink package in which a negative pressure can be applied to ink being supplied to a print head without requiring an ink supply pressure regulating means. SOLUTION: When an ink package 30 is contained in an ink cartridge 40 and then the ink cartridge 40 is slid in the direction of an arrow X, an ink extraction member 22 is inserted into a through hole 42 and then the ink extraction member 22 is thrust into the ink encapsulating part 31 of the ink package 30.

Title: Output circuit
Inventor: UENO SHOJI
IPC: H03K19/00
Filed: 1989-10-06
Abstract: PURPOSE:To improve the load driving capability by using a 1st bipolar transistor(TR) to absorb a ringing at the level transition in which ringing is easily caused at the output in an IC comprising the bipolar TR and the MOS TR in mixture, and energizing a 2nd MOS with a large size after stabilization. CONSTITUTION:When a signal output node 12 is discharged to get an L level, it is executed by turning on a bipolar TR 15 to suppress production of output ringing. After an output signal OUT is made stable at an L level, a MOS TR 18 is turned on in addition to the TR 15 to discharge the output node 12. Thus, steady-state load driving capability is sufficiently increased and since no steady- state current flows between a power level VCC and a ground level GND, low power consumption equal to a conventional CMOS.IC is attained.
