Abstract: PURPOSE:To form a flat Al wiring layer by a method wherein an Al film with the thickness enough to fill up a groove formed on an interlayer insulating film is formed; successively overall surface is coated with photoresist; and finally the photoresist and the Al film are removed by etching process at uniform rate. CONSTITUTION:An interlayer insulating film 2 1.6mum thick formed on a substrate 1 is evenly coated with a photoresist film 3 1.6mum thick. Then a groove 0.8mum deep is formed by reactive ion etching process on the interlayer insulating film 2 using the photoresist film 3 as a mask. Next an Al film 4 with the same thickness as the depth of groove is formed on the interlayer insulating film 2 by MOCVD process. Successively the Al film 4 is spin-coated with photoresist 5 making the surface flat. Finally the photoresist 5 and the Al film 4 are removed by the reactive etching process at uniform rate to leave an Al wiring layer 6 only buried in the groove.

Abstract: PURPOSE:To keep the transmission electric power at a fixed level by controlling the attenuation value of a variable attenuator based on the desired transmission output level of each modulator performing a transmitting action as well as the non-linear input/output characteristics of a large electric power amplifier and compensating the gain fluctuation due to said input/output characteristics. CONSTITUTION:The desired transmission electric power of each carrier and the non-linear input/output characteristics of a large electric power amplifier 5 are previously written and stored into a transmission gain control computing element 7. The ON/OFF states of the transmission carriers are controlled by modulators 11-1n and these control information are supplied to the element 7. The element 7 calculates the total transmission electric energy and the desired gain controlled variable and controls the attenuation value of a variable attenuator 4 to compensate the gain fluctuation due to the non-linear input/output characteristics of the amplifier 5. Thus the transmission gain fluctuation is corrected and the transmission electric power of each carrier is kept at constant level.

Title: Method and apparatus for removing air from ink jet type print head
Inventor: THOMAS P CORTONY
IPC: B41J2/015
Filed: 1998-05-14
Abstract: PROBLEM TO BE SOLVED: To remove an air pocket effectively from the reservoir in an ink jet print head using a pressure reduction technology. SOLUTION: A print head 12 comprises a nozzle 27 and a reservoir 34 wherein the reservoir inlet 32 is applied tightly to a cartridge 10. When a high vacuum pressure 15 applied from a high vacuum source 22 to the nozzle 22 and a vent 18 of the cartridge 10, air pockets in the head and the cartridge are enlarged through pressure reduction. Since the fluid resistance of a channel to the nozzle 27 is lower than that of the reservoir inlet 32, the air pocket in the reservoir 34 is passed through the inlet 32 and combined with the air pocket in the cartridge 10. The air pocket in the cartridge 10 is reduced upon release of vacuum and the air pocket in the reservoir 34 having adverse effect on the print quality is eliminated. The vacuum source may be coupled with a container containing a plurality of cartridges 10 or accessories including the vacuum source may be fixed to a printer.
