Patent JP-H11227214-A (JP)
Title: Manufacture of ink jet recording head
Inventor: MATSUZAWA AKIRA
IPC: B41J2/045
Filed: 1998-02-13
Abstract: PROBLEM TO BE SOLVED: To prevent crosstalks by setting a thickness of a base substrate larger than a height of an ink pressure chamber, etching the base substrate in conformity with a formation pattern of a piezoelectric layer, forming a pattern of the ink pressure chamber and etching thereby reducing a total thickness of the pressure chamber of the base substrate. SOLUTION: A total thickness H1 of a base substrate 10 is maintained within a range where no problem is brought about in handling the base substrate in a manufacture process. Since the base substrate is divided to individual chips, the rigidity is not lost even when the thickness of the substrate 10 is reduced. The film thickness of the base substrate can be freely controlled by controlling a film thickness of a silicon dioxide mask 102, and therefore the film thickness of the base substrate of an inkjet type recording head can be reduced eventually while the rigidity of the base substrate is maintained. In consequence, a compliance of an ink pressure chamber can be decreased and crosstalks can be prevented. The base substrate can be thinned without obstructing the handling during the manufacture.

Abstract: PURPOSE:To decrease the power consumption of a semiconductor memory device by performing the precharging and balancing operations when the word line of a selected block has a fall immediately before said block is set under a non-selection state after a group of bit line pairs is divided into plural parts and data are delivered. CONSTITUTION:The (m X n) pairs of bit line groups are divided into (m) pieces of blocks by (m) pieces of logical gates NOR1-NORm and a timing generating circuit 14 receives the change of the address input signal AiY and controls the output timing of a column decoder.

Here the logic is secured by both gates NOR1 and NOR2 between the precharging/balancing signal pulse phi and both outputs Y1 and Y2. Then precharging/balancing signals phi1 and phi2 are produced. On other words, the signal phi1 (phi2) is produced only at a block 1 (2) immediately before this block 1 (2) is set under a non-selection state and by the change of address input signals AiX and AiY.
