A synchronizer for coupling a corrective servo mechanism to a pneumatic altitude sensor in an aircraft to provide a display with a positive pressure altitude indication. The synchronizer has a first rotor retained on a shaft with gear teeth that are positively engaged with the servomotor. The synchronizer has a second rotor concentric to said first rotor with gear teeth that positively engage the altitude sensor. A coil in the synchronizer is energized and lines of magnetic flux developed which ...

In a semiconductor device having a capacitor and a method of fabricating the same, the semiconductor device comprises a semiconductor substrate and an insulating layer on the semiconductor substrate, a contact plug electrically connected to the semiconductor substrate and formed in the contact hole, a buffer conductive layer pattern electrically connected to the contact plug and formed on the insulating layer and the contact plug, an etching stopping layer formed on the buffer conductive layer p...

An integrated circuit structure includes a digit line and an electrode adapted to be part of a storage cell capacitor and includes a barrier layer interposed between a conductive plug and an oxidation resistant layer. An insulative layer protects sidewalls of the barrier layer during deposition and anneal of a dielectric layer. The method includes forming the conductive plug recessed in an insulative layer. The barrier layer is formed in the recess and the top layer. An oxidation resistant condu...

A method for forming double-sided capacitors for a semiconductor device includes forming a dielectric structure which supports capacitor bottom plates during wafer processing. The structure is particularly useful for supporting the bottom plates during removal of a base dielectric layer to expose the outside of the bottom plates to form a double-sided capacitor. The support structure further supports the bottom plates during formation of a cell dielectric layer, a capacitor top plate, and final ...

A method for manufacturing capacitors is disclosed. The method is applicable to a capacitor whose upper electrode area is smaller than the lower electrode area. It is featured in that a material, such as a TiN hard mask, is inserted between the conventional electrode metal layer and photo resist layer. This enables one to perform the in-situ photo resist layer removal step after dry etching the upper electrode metal. Since the photo resist layer removal step uses oxygen plasma, the surface of th...

It is a light weight device that can be disasembled in a very short time to allow a person to move it from one floor to another. The platform can be used as a dolly when not being use as a lift or a work bench to hold screw gun and supplies when using as a lift. It saves the overhead of extra manpower by enabeling one man to raise the material all the way from the floor to the ceiling and hold it in place. Anyone can use it, no technical skills required. If desired the winch can be replaced with...

A method is described for making an array of dynamic random access memory (DRAM) cells having both a trench and a stacked capacitor within each cell. The method involves forming a trench in the silicon substrate at the capacitor node contact area of the DRAM cell, and depositing an N+ doped polysilicon layer to form an N+/P diode capacitor in the trench. Another N+ doped polysilicon layer is deposited and anisotropically etched back over a patterned silicon nitride/silicon oxide layer in the tre...

A method for increasing cardiotonic contractility in humans or other animals using a class of benzodiazinone-pyridazinone and hydroxy-pyrazolyl compounds and pharmaceutical compositions including the same.

Low-k dielectric materials are incorporated as an insulator material between bit lines and an inter-level dielectric material. The device is first processed in a known manner, up to and including the deposition and anneal of the bit line metal, using a higher dielectric constant material that can withstand the higher temperature process steps as the insulator between the bit lines. Then, the higher dielectric constant material is removed using an etch that is selective to the bit line metal, and...
