Title: Inkjet head
Inventor: HIGASHIMURA KOICHI
IPC: B41J2/055
Filed: 1988-07-21
Abstract: PURPOSE:To improve the efficiency by deforming a pressure generating member by Maxwell's force of an electric field extended between electric charges of reverse polarity injected into said pressure generating member and a corresponding electrode portion upon application of a voltage thereby to change the pressure of ink present in a gap between said pressure generating member and a nozzle forming substrate to discharge drops of ink from a nozzle. CONSTITUTION:A gap 15 between a pressure generating member 13 and a nozzle forming substrate 11 is secured by an electrically insulating spacer 16. When a voltage 17 is applied, an electric charge of reverse polarity is injected into the gap 15. A corresponding electrode portion 18 of the pressure generating member 13 is formed of a part of the substrate 11. When the voltage 17 is applied between the member 13 and substrate 11, electric charges of reverse polarity are injected to the member 13 and corresponding electrode portion 18. Because of the Maxwell's force of an electric field spread between the electric charges of reverse polarity, the pressure generating member 13 is deformed towards the substrate 11. This deformation of the member 13 increases the pressure of the ink present in the gap 15 between the member 13 and substrate 11, and consequently ink drops 19 are discharged out of a nozzle 12.

Title: Data backup system for disaster preventing system
Inventor: KANAZAWA YUICHI
IPC: G08B23/00
Filed: 1989-07-15
Abstract: PURPOSE:To simplify the backup of disaster preventing data by transferring disaster preventing data from a storage means when the disaster data stored in a RAM are broken and storing the transferred data in the RAM. CONSTITUTION:When a change in disaster data is necessary, a ROM card 10 on the system side 8 is changed and data are transferred. Even when data are broken on the receiver A side due to the temporary rewriting of disaster preventing data in the RAM 9 to execute debugging or a test or the exhaustion or battery capacity, the original disaster preventing data can be simply recovered by transferring data from the system 8 because the data are left in the system 8. Thereby, it is unnecessary to send the disaster data to a communication circuit in the receiver again by using a conventional data register.

Title: Window glass able to shield light
Inventor: HIROSE TORU
IPC: E06B3/66
Filed: 1989-07-14
Abstract: PURPOSE:To provide a window glass which makes it possible to instantly shield the light and restores transparency by placing parallelly two glass plates to form a very small gap therebetween and supporting the periphery thereof by a frame to feed colored liquid into said gap or to suck it out therefrom. CONSTITUTION:Two glass plates 1, 2 constituting a window glass are placed parallelly to form a very small gap 3 therebetween and supported by a frame 6, wherein a hole 7 is provided for venting air on the upper section of the frame 6. And a colored liquid 8 is put into a vessel 4 which is connected to the gap 3 through a motor-driven pump 5. When the pump 5 is driven in a normal direction to force the liquid 8 into the gap 3, the transparent glass assumes color to shield the light, whereas when the pump is rotated in a reverse direction, the liquid 8 is sucked out of the gap 3 and sent to the vessel 4, causing thereby the glass to restore transparency, while the air in the gap 3 flows out or in through the hole 7. As a result, a shield device which causes low noise and requires a limited amount of space for installation and acts quickly can be obtained.
