Title: Pressure detector
Inventor: NISHIDA MINORU
IPC: G01L9/04
Filed: 1986-06-11
Abstract: PURPOSE:To enhance the pressure receiving sensitivity of a detector and to facilitate the miniaturization, manufacturing and assembling of a housing, by providing an opening to the side wall of a sensing body and mounting a pressure receiving diaphragm comprising a ceramic plate to said opening so to cover the same. CONSTITUTION:A detector has a cylindrical housing 3 and a metal cylindrical sensing body 2 is held to the opening 21 provided to the leading end of the housing 3 faced to the interior of a pressure chamber in an airtight manner. The opening 21 is provided to the side wall of the sensing body 2 and a pressure receiving diaphragm 1 comprising a ceramic plate is mounted to the opening 21 so as to cover the same. Further, strain gauge elements 4A-4D are bonded and fixed to the inside surface of the pressure receiving diaphragm 1. Since the pressure receiving diaphragm 1 is arranged in parallel to the axis of the housing 3, it is unnecessary to enlarge the diameter of the housing 3 even when a pressure receiving area is enlarged in order to enhance pressure receiving sensitivity to make the detector large-sized and the detector can be miniaturized as a whole. Since it is unnecessary to mount the sensing body 2 in the housing 3, manufacturing and assembling can be easily performed.

Filed: 1989-05-29
Abstract: PURPOSE:To make it possible to prevent a jet head from becoming dry if printing is continued for a long time by allowing a carriage to move to an ink ejection position to eject ink from the head using a counter device, if a predetermined counter value is reached. CONSTITUTION:A counter is reset if a carriage 25 is located at a standby position 21. If the carriage 25 leaves the standby position, that is, if printing is started, the count begins. If a counter value reaches a predetermined level, a carriage position is stored in RAM 5, and the carriage 25 moves to an ink ejection position to eject ink from all the nozzles of the head 7. In this way, it is possible to prevent the unused nozzles from becoming dry. If the ejection of ink from all the nozzles is completed, the counter is reset to resume counting. Next a print resumption position is retrieved from a carriage position storage area in RAM 5, then a CR motor 3 is driven to return the carriage to its print resumption position and printing is resumed when the carriage has returned.
