Title: Ink jet record head
Inventor: FUKAZAWA NAOTO
IPC: B41J2/135
Filed: 1990-10-18
Abstract: PURPOSE:To stabilize jetting direction, make speed fast, and improve print quality by providing a nozzle having a constant depth, an open end whose width is the narrowest, a part whose width widens as it proceeds to the inside, and a parallel part subsequent thereto. CONSTITUTION:A nozzle 2 comprises a tapered part A and a parallel part B, and a depth D is common to them and constant. Since a pressurized ink is introduced by the comparatively long parallel part B, the direction of ink jet stabilizes. On the other hand, a flowing resistance reduces due to the width of the parallel part B and a loss of a pressure force supplied at a pressurized room reduces. When the ink moves from the parallel part B to the opening of the nozzle 2, a flowing speed at the opening of the nozzle increases due to a tapered throttle 2theta. When angles of each side face of the tapered part with respect to a center line of the nozzle are 20 deg.-30 deg., jet velocity becomes the fastest and flying distance becomes the longest, thereby improving print quality.

Title: Data storing method
Inventor: UEDA ETSUKO
IPC: G06F12/02
Filed: 1986-11-26
Abstract: PURPOSE:To avoid increase of the memory capacity even when a 2-byte character is processed by storing the data shown in the normal expression into a buffer after designating the number of working buffers for each data. CONSTITUTION:In a step 1 a buffer consisting of a CCL code storing area 1, a working buffer number designating area 2 and a data area 3 is designated. The area 3 is expanded and contracted in response to the quantity of the character data to be processed. In a step 2 the data shown in the normal expression is stored in a designated buffer. In such a way, the character data is not stored in a bit table but in a buffer whose capacity varies according to the data quantity. Therefore the memory capacity is never increased even with a 2-byte character.
