摘要:
An electrostatic actuator has: an upper structure that is connected, via an arm, to a supporting base provided on a substrate and is supported in a space existing over the substrate; a lower structure that is provided in a substrate position in such a way as to oppose the upper structure; an inclination structure that is provided with respect to either one of the upper structure and the lower structure so as to make small the distance between the upper structure and the lower structure; and one or more electrodes that are provided with respect to the other structure in corresponding relationship to the inclination structure.
摘要:
A microswitch is realized that can be driven by low voltage, and at the same time, that has increased impedance between switch terminals when the switch is OFF. The relation between upper electrode (4), lower electrode (6), contact electrode (7), and signal lines (8) is arranged such that the minimum distance between contact electrode 7 and signal lines 8 is greater than the minimum distance between upper electrode 4 and lower electrode 6 when the microswitch is in the OFF state.
摘要:
In an ink jet head including a substrate having a opening for a pressure chamber, a section of the opening is gradually increased from a front surface of the substrate to an intermediate level of the substrate and is gradually decreased from the intermediate level of the substrate to a back surface of the substrate. The opening at the front surface of the substrate serves as a nozzle.
