Title: Order wire radio communication system
Inventor: AKUTSU SHIYOUJI
IPC: H04B1/64
Filed: 1989-11-14
Abstract: PURPOSE:To improve the response of a compander and an expander by sending an out-band tone signal bringing the compander and the expander into the operating state only when there is no order wire signal to be sent. CONSTITUTION:A compander 2 and an expander 3 apply the compression of a transmission level and the expansion of a reception level with a gain corresponding to the level of the out-band tone signal by sending the out-band tone signal bringing the compander 2 and the expander 3 into the operating state only when an order wire signal to be sent is not present thereon.

Title: Inkjet head
Inventor: KITAHARA TSUYOSHI
IPC: B41J2/045
Filed: 1988-11-21
Abstract: PURPOSE:To offer an ink feed apparatus which is high in reliability and stability without leaking an ink by providing a pressure generating means for generating a pressure to an ink enabling said ink to fly in the form of ink drops, and constituting a nozzle forming member of a plurality of first plate members and a second plate member generally orthogonal to said first plate members via a narrow gap. CONSTITUTION:When a selective electric signal is applied to a vibrator 24, a piezoelectric element shrinks because of the piezoelectric effect, whereas a foil member which is high in rigidity is restricted to change its size. Accordingly, the vibrator is deformed and shifted to the side of a nozzle plate 21, whereby a pressure is generated at a very small gap between the vibrator 24 and nozzle plate 21. Since first plate members 29, 30, 31 placed orthogonal to a second plate member all communicate to a narrow gap D2 defined by the second plate member, the fluid resistance of a narrow gap D1 can be reduced for the flow of the ink 32 consequent to the consumption and discharge of the ink, thereby causing no shortage of the ink.
