Title: Ink-jet recording apparatus
Inventor: AKAO YUJI
IPC: B41J2/165
Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To prevent ink from being wasted, by forming a butting part of an elastic body, butting the butting part to a nozzle formed in a head, and preventing ink injected into the nozzle from being dried with the use of a seal member which can tightly seal the nozzle. SOLUTION: A seal member is formed of an elastic body of rubber or the like, having projections 102 formed on a base 100 to tightly close nozzles. A head 2 has a plurality of nozzles 110, 112, 114 arranged in a vertical direction to a paper face to discharge a plurality of colors of ink. The inks are injected in corresponding nozzles. The projections 102 tightly adhere to a wall face of the head in the vicinity of the nozzles thereby maintaining the sealing. The projections 102 form a sealed space without touching the nozzles, so that the ink in the sealed space hardly evaporates. Discharging of the ink is ensured for a long term. Moreover, since the seal member seals with the small sealed space, the seal member can be formed in one body with a wiper and a cap.

Abstract: PURPOSE:To initialize automatically all bits to logical ''0'' or ''1'', by making numbers of elements of flip flop circuits constituting memory cells unbalanced to turn on one driving MOSFET at a power-on time. CONSTITUTION:The conductance of a storage MOSFET Q1 is made larger than that of a storage MOSFET Q2 as a method (1). A dummy capacity is added to the gate of the storage MOSFET Q2 to make the gate capacity value of the MOSFET Q2 larger than that of the MOSFET Q1 as a method (2). A resistance R1 for holding information is set to a resistance value larger than that of a resistance R2 as a method (3). A source or drain resistance means of said Q0 is inserted as a method (4). One of these methods is adopted or they are combined. By making element constants unbalanced by these methods, the potential of a node N2 to which the gate of the MOSFET Q1 is connected is raised to the high level more quickly than that of a node N1, to which the gate of the MOSFET Q1 is connected, at a power-on time to stabilize the MOSFET Q1 in the turn-on state and stabilize the MOSFET Q2 in the turn-off state. Thus, all bits are set to a desired initial state automatically to make an initializing program unnecessary.
