摘要： Along a region where a scribe line is formed on a surface of a glass substrate 50, a laser spot is continuously applied for heating at a temperature lower than a softening point of the glass substrate 50, and a region in the vicinity of the heated region is cooled. In this manner, a blind crack is formed along a line to be scribed. A detection unit 40 applies light to the blind crack, immediately after formed in the vicinity of to a cooling spot, through an optical fiber 41. When the blind crack has been formed, part of the light is obtained in the optical fiber 41 because of diffuse reflection. Therefore, detection of the level of this reflected light allows checking as to whether the blind crack has been normally formed or not.

摘要： Undesirable deflection of partitioning walls between ink pressure chambers is prevented during ink discharge operations even when the partitioning walls are made very thin to achieve a high density inkjet head. The diaphragms of the discharge nozzles of the inkjet head as well as the diaphragms of the non-discharge nozzles are all driven to contact the corresponding individual electrodes, and this diaphragm to individual electrode contact state is maintained in the non-discharge nozzles while the diaphragms of the discharge nozzles are released from individual electrodes to discharge ink. After printing is completed the diaphragms of the non-discharge nozzles are slowly released from the corresponding individual electrodes at a speed that will not cause undesirable ink discharge. By thus maintaining low compliance in the ink pressure chambers of the non-discharge nozzles, deformation of the partitioning walls between discharge and non-discharge nozzles due to change in the ink pressure can be reliably prevented. A drop in ink discharge performance due to such partitioning wall deformation can be reliably prevented, and printing with high resolution, precise print quality can be easily achieved.
摘要翻译：即使当分隔壁非常薄以达到高密度喷墨头时，在喷墨操作期间也防止了油墨压力室之间的分隔壁的不期望的偏转。喷墨头的排出喷嘴的隔膜以及非排出喷嘴的隔膜都被驱动以接触相应的单个电极，并且该隔膜保持在非排放喷嘴中，而隔膜保持在单独的电极接触状态的排出喷嘴从各个电极释放以排出墨。在完成打印之后，不排出喷嘴的隔膜以不会导致不期望的墨水排放的速度从相应的单独电极缓慢释放。通过这样维持在非排出喷嘴的墨压力室中的低柔顺性，可以可靠地防止由于墨压力的变化引起的排出喷嘴与非排放喷嘴之间的分隔壁的变形。可以可靠地防止由于这种分隔壁变形引起的喷墨性能下降，并且可以容易地实现具有高分辨率，精确打印质量的打印。

摘要： An ink-jet head ejects an ink droplet from an ink nozzle by the charging and discharging between a counter electrode and vibrating plates. The counter electrode comprises a main electrode and an auxiliary electrode, which is provided on the ink-nozzle's side in common with the vibrating plates. Auxiliary charging between the auxiliary electrode and the vibrating plates is effected to vibrate a meniscus in the ink nozzle without ejecting a useless droplet. Consequently, the ink is prevented from forming a film on the meniscus, and an increase of the viscosity of the ink due to evaporation of the ink solvent is prevented by diffusing the ink in the ink passage.

摘要： An electrostatic ink-jet head (1) in which the present invention is applied comprises a pressure chamber (6) communicating with an ink nozzle (21), and an atmospheric pressure chamber (12) opened to the atmosphere, with a vibrating plate (5) being provided on the base plane of the pressure chamber (6). Voltage applied between the vibrating plate (5) and an electrode (43) causes the vibrating plate (5) to vibrate due to electrostatic force, thereby discharging ink droplets. A vibrating chamber (41) communicates with a pressure compensating chamber (49), and a displacement plate (16) capable of being displaced in the direction outward from the plane according to fluctuations in the external, atmospheric pressure is formed at the base plane of the pressure compensating chamber (49). Displacement of the displacement plate (16) increases/decreases the volume of the pressure compensating chamber (49), and the internal pressure of the vibrating chambers (41) communicating thereof is adjusted to match the external atmospheric pressure. Accordingly, the vibration properties of the vibrating plate (5) can be maintained constant even when the external atmospheric pressure fluctuates, and proper ink droplet discharging action can be maintained.

摘要： Methods for manufacturing an electrostatic actuator that comprises electrode members having opposing surfaces with a gap disposed therebetween. In an ink jet head, a bottom surface of a diaphragm may be one of the electrodes (common electrode) of an eletrostatic actuator, the diaphragm forming a wall of an ink chamber in the ink jet head that is displaced relatively by an electrostatic force. A hydrophobic film, preferably hexamethyldisilazane (HMDS), is formed on at least one of the opposing electrode surfaces to improve the durability of the electrostatic actuator so that electrostatic attraction between opposing electrode members does not decrease and the opposing electrode members do not stick together. HMDS molecules are smaller than PFDA molecules, and a uniform, variation-free hydrophobic film can therefore be formed even when the gap between opposing electrodes is narrow. Durability and film stability of a HMDS hydrophobic film are also high. An electrostatic actuator with high durability and operating stability can thus be achieved.
