Planar capacitor memory cell and its applications

InactiveUS7209384B1Less complicated to fabricateImprove performanceTransistorSolid-state devicesHemt circuitsEngineering
A capacitor memory is realized, wherein a capacitor stores data and a diode controls to store data “1” or “0”. Diode has four terminals wherein first terminal serves as word line, second terminal serves as storage node, third terminal is floating, and fourth terminal serves as bit line, wherein back channel effect is suppressed adding additional ions in the bottom side of third terminal or applying negative voltage in the well or substrate. A capacitor plate couples to second terminal, which plate has no coupling region to first, third and fourth terminal. With no coupling, the inversion layer of plate in the storage node is isolated from the adjacent nodes. In doing so, the plate can swing ground level to positive supply level to write. As a result, no negative generator is required for controlling plate. Word line and bit line keep ground level during standby, and rise to supply level for read or write operation. In this manner, no holding current is required during standby, and operating current is dramatically reduced with no negative generator. Write has a sequence to clear the state of cell before writing to store data regardless of previous state. Refresh cycle is periodically asserted to sustain data. The present invention can be applied for destructive read, or for nondestructive read adding pull-down device to bit line. The height of cell is almost same as control circuit on the bulk or SOI wafer.

Conversion of carbohydrates to hydroxymethylfurfural (HMF) and derivatives

A method of producing substantially pure HMF, HMF esters and other derivatives from a carbohydrate source by contacting the carbohydrate source with a solid phase catalyst. A carbohydrate starting material is heated in a solvent in a column and continuously flowed through a solid phase catalyst in the presence of an organic acid, or heated with the organic acid and a solid catalyst in solution to form a HMF ester. Heating without organic acid forms HMF. The resulting product is purified by filtration to remove the unreacted starting materials and catalyst. The HMF ester or a mixture of HMF and HMF ester may then be oxidized to 2,5-furandicarboxylic acid (FDCA) by combining the HMF ester with an organic acid, cobalt acetate, manganese acetate and sodium bromide under pressure. Alternatively, the HMF ester may be reduced to form a furan or tetrahydrofuran diol.

Heart valve prosthesis and method of manufacture

A cardiac valve prosthesis having a frame and two or more leaflets (preferably three) attached to the frame. The leaflets are attached to the frame between posts, with a free edge which can seal the leaflets together when the valve is closed under back pressure. The leaflets are created in a mathematically defined shape allowing good wash-out of the whole leaflet orifice, including the area close to the frame posts, thereby relieving the problem of thrombus deposition under clinical implant conditions.

Golf club head

A metal wood golf club head is provided having a front face with an impact zone including a compliant area. Preferably, the compliant area is disposed in an upper portion of the front face. Preferably, a through-slit is provided in the front face to form the compliant area. The through-slit may be an elongated slot substantially parallel to a top of the front face and may include an elastomeric reinforcement. The compliant area creates an ultra-low center of gravity relative to the geometric face center, resulting in higher launch angles and spin rate ratios. The compliant area upwardly shifts the coefficient of restitution to the geometric center of the face and thereby increases the carry distance of a golf ball hit off the club head.

A sonic actuator including a multi-layer membrane having a non-metallic elastomeric dielectric polymer layer with a first surface and a second surface, a first compliant electrode layer contacting the first surface of the polymer layer, and a second compliant electrode layer contacting the second surface of the polymer layer. The actuator further includes a support structure in contact with the sonic actuator film. Preferably, the non-metallic dielectric polymer is selected from the group consisting essentially of silicone, fluorosilicone, fluoroelastomer, natural rubber, polybutadiene, nitrile rubber, isoprene, and ethylene propylene diene. Also preferably, the compliant electrode layer is made from the group consisting essentially of graphite, carbon, and conductive polymers. The support structure can take the form of grid having a number of circular apertures. When a voltage is applied to the electrodes, portions of the film held at the aperture of the support structure can bulge due to the electrostriction phenomenon. The resultant “bubbles” can be modulated to generate sonic vibrations, or can be used to create a variable surface for airflow control.

Golf club head with progressive face stiffness

A metal wood golf club head adapted for attachment to a shaft, with a body comprising of a first body portion and a second body portion, each portion constructed of a different density material. Combining a high density material in the first body portion with a low density material in the second body portion, creates an ultra-low center of gravity relative to the geometric face center, resulting in higher launch angles and spin rate ratios. Thickening the lower area of the front face lowers the center of gravity and upwardly shifts the coefficient of restitution to the geometric center of the face.
