Title: Ink jet head
Inventor: HIGASHIMURA KOICHI
IPC: B41J2/14
Filed: 1988-06-03
Abstract: PURPOSE:To simultaneously improve various characteristics such as ink droplet discharging speed, amount and response by forming the side face of a nozzle of a substance having a specific angle to the ink. CONSTITUTION:When a voltage is applied to a piezoelectric element 13, the element 13 is contracted, a pressure generating member 15 is deformed to the direction of a nozzle forming board 11 by the bimetal action composed with a metal plate 14. Then, the pressure of ink presented in a gap 23 is enhanced, and ink droplet 24 is discharged from a nozzle 12. The suction of a nozzle meniscus 26 after discharging is recovered by the capillary force of the ink, and next voltage signal is waited for. In this case, since a substance having a contact angle of 90 deg. or more to the ink 16, i.e., a substance moistened with the ink 16 is employed on the side face 17 of the nozzle 12, the viscous resistance of the ink in the nozzle is held small, and the flow of the ink in a nozzle outlet opening is stabilized by the presence of the side face 17. Accordingly, various characteristics such as ink droplet discharging speed, amount and stability can be simultaneously improved.

Abstract: PURPOSE:To replace dopants to the positions of crystal lattices stably by adding isoelectronic impurities while adjusting their quantity so as just to ease the strain around superhigh-density dopants, when superhigh-density doping is done to compound semiconductor crystals. CONSTITUTION:Impurities workable as acceptors or donors are doped with superhigh-density to the crystals of compound semiconductors of two or more kinds.

When a mixed crystal is formed by adding isoelectronic impurities being the same as the doped crystal, to compensate this variation, individual bond distances forming the mixed crystal are made clear, and isoelectronic impurities are added suppressing the amount so as to compensate these distances specifying the bond distances of atoms around dopants, in a degree of not producing misfitting dislocation between the lower layer and the upper one.
