Title: Manufacture of ink jet head
Inventor: SUGA KIYOMITSU
IPC: B41J2/16
Filed: 1994-06-23
Abstract: PURPOSE:To maintain transparency of an ink jet head that is formed so that a glass diaphragm is heat-bonded to a passage substrate made of photosensitive glass and to prevent a crack of the diaphragm from being generated due to a thermal stress. CONSTITUTION:A photosensitive glass 1 is basically exposed and etched to form a passage groove and a diaphragm 3 made of a glass plate is brought into contact with a face where the passage groove is formed and they are heat-bonded with each other, thereby manufacturing the title device. Since a borosilicate glass of which melting point and coefficient of linear expansion are lower than those of the photosensitive glass is used for the material of the diaphragm 3, it is possible to execute the heat-bonding at a temperature of a crystallization point of the photosensitive glass (about 800 deg.C) or less. As a result, a non-exposure section of a passage substrate is not crystallized in the heat-bonding process so that transparency of the photosensitive glass is not lost, thereby it is convenient to observe an inner section of the ink passage. When a heat stress due to the difference of the coefficient of linear expansion between the diaphragm and passage substrate occurs, a crack does not generated because a compressing stress acts on a junction face of the diaphragm and passage substrate.
