  • Patent number: 7905562
    Abstract: To provide a liquid guiding device such that, when liquid is dumped onto a sloping guiding surface portion located in a region where ink is dumped, the liquid is easily guided to an ink absorber and no liquid remains on the guiding surface portion. A guiding surface portion 29 is provided in a liquid dumping region 23 in which ink absorbers 25 and 26 are provided and on the upstream edge of a downstream portion 24 of a platen. The upper surface of the guiding surface portions 29 slopes down toward the upstream side, that is, toward the liquid dumping region 23. In the guiding surface portion 29 is formed a guiding structure portion 31 that guides ink attached to the guiding surface portion to the ink absorber 25. The guiding structure portion may include an edge portion 31 that guides liquid by capillary action. The edge portion may extend to the ink absorbers 25 and 26.

  • Patent number: 7052995
    Abstract: A buried film and a barrier film are polished together using a slurry in which the polishing rate on a substrate material (in particular, silicon oxide), that on a buried-film material (in particular, tungsten) and that on a barrier-film material (in particular, titanium oxide) are substantially equal to one another. This can materialize a buried structure free from any step or steps, at a high polishing rate.

  • Patent number: 6309057
    Abstract: In an ink-jet type recording head including a nozzle plate provided with nozzle openings, a spacer provided with partitions for partitioning pressure generating chambers, ink supply ports and reservoirs, and a plate member sandwiched and fixed together. Displacement of the plate member is produced by piezoelectric vibrators to thereby generate ink droplets. The spacer is formed by anisotropic etching of a silicon single crystal substrate so that the pressure generating chambers, the ink supply ports and the reservoirs are formed as through-holes communicated with each other. Accordingly, etching conditions for the respective through-holes are made equal to each other. Particularly, through-holes small in sectional area such as the pressure generating chambers and the ink supply ports can be formed with a high accuracy.

  • Patent number: 5880497
    Abstract: A SRAM having its memory cell constructed to include transfer MISFETs to be controlled by word lines and a flip-flop circuit having driver MISFETs and load MISFETs. Plate electrodes of large area fixed on predetermined power source lines are arranged over the load MISFETs such that the plate electrodes over the offset region of the load MISFETs are formed with an opening. A silicon nitride film having a thickness permeable to hydrogen but not to humidity is formed over the transfer MISFETs and the driver MISFETs formed over the main surface of a semiconductor substrate and the load MISFETs formed of a polycrystalline silicon film deposited on the driver MISFETs.
