Abstract: PURPOSE:To prevent a breakdown of a partition due to a reaction of an extreme stress by forming the partition of a pressure chamber which surrounds pressure generating means from all-round direction and forming an ink supply passage in a clearance with a back face of a second plate, and forming the partition by a multilayer structure having thick wall at a base and thin wall at an end. CONSTITUTION:A partition 54 of a pressure chamber 33 has a two-layer structure having thin wall at an end 55 and thick wall at a base 56. Here, upper and lower pressure chamber layers 57 and 58 forming positions 55 and 56 of the partition 54 are made of photosensitive polyimide having about 5 - 15mum thick. The pressure chamber 33 is shaped in a square of which 1 side is about 70mum in length. The wall thickness of the base 56 is about 100mum and about 30mum at the end 55. In this ink jet printer head 53, a supply passage layer 59 is made of the photosensitive polyimide only at the peripheral circumference of the device having a layer thickness of about 10mum. therefore, a breakdown of the partition due to a pressure generated by pressure generating means can be prevented. Thus, an ink jet printer head having a simple structure and excellent durability and responsibility can be obtained.

Title: Character processor
Inventor: SAKAKIBARA ATSUSHI
IPC: G06F17/22
Filed: 1990-06-15
Abstract: PURPOSE:To easily offer a character string to be converted as a candidate by providing the character processor with a combinational information dictionary storing means constituted of respective fields and a means for converting an inputted 'KANA' (Japanese syllabary) reading string into a prescribed character string based upon the contents of the information dictionary storing means. CONSTITUTION:When field names in an example dictionary to be applied to 'KANA'/'KANJI' (Chinese character) conversion are displayed on a window display screen, an operator sets up a cursor position to a 'domestic medical field' e.g. by a cursor moving key. When the operator inputs the reading of the set contents by 'KANA' keys, displays the reading on an area for displaying the reading input of 'KANA'/'KANJI' conversion and then depresses a conversion key, 'KANA'/'KANJI' converted character string candidates are displayed. Since the cursor key is set up to the 'domestic medical field', a conversion candidate 'catch a cold' is displayed at first and other conversion candidates in the example dictionary are successively displayed. When the operator depresses a 'selection' key, the character string 'catch a cold' is inputted to a text buffer.
