Granted: 2001-04-21
Abstract: Disclose herein is a ferroelectric random access memory (FRAM) device which comprises a word line, a plate line, a bit line, and a ferroelectric memory cell. The ferroelectric memory cell is comprised of a ferroelectric capacitor and a select transistor. One electrode of the ferroelectric capacitor is coupled to the bit line through the select transistor, and the other electrode thereof is coupled to the plate line, and wherein a control electrode of the select transistor is coupled to the word line. The FRAM device further comprises a plate pulse generator for producing a plate pulse signal to be provided into the plate line. The plate pulse signal has different voltage levels according to modes of operation. So, ferroelectric material inserted between both electrodes of the ferroelectric capacitor associated with the plate line is completely polarized. Accordingly, a sensing margin of the memory cell is increased during the read operation, resulting in an reliability improvement of the ferroelectric random access memory device.

Title: Metallization process and method
Inventor: NAIK MEHUL B
IPC: C23C14/16
Filed: 1998-09-30
Granted: 2000-06-11
Abstract: The invention generally provide an improved process for providing uniform step coverage on a substrate and planarization of metal layers to form continuous, void-free interconnections in high aspect ratio, sub-half micron application. The invention provides a multi-step PVD process in which the plasma power is varied for each of the step to obtain favorable fill characteristics as well as good reflectivity, morphology and throughput. The initial plasma powers are relatively low to ensure good, void-free filling of the aperture and, then, the plasma powers are increased to obtain the desired reflectivity and morphology characteristics. The invention provides an aperture filling process comprising physical vapor depositing a metal over the substrate and varying the plasma power during the physical vapor deposition. Preferably, the plasma power is varied from a first discrete low plasma power to a second discrete high plasma power. Even more preferably, the plasma power is varied from a first discrete low plasma power to a second discrete low plasma power to a third discrete high plasma power.

Title: Arc deburring of electrochemical cell electrodes
Inventor: HOY WESLEY
IPC: B23K9/013
Filed: 1999-03-15
Granted: 2001-01-21
Abstract: The present invention provides devices and methods for deburring conductive articles. Particularly, the devices and methods are applied to deburr electrochemical cell electrodes prior to their assembly into completed cells. A electrode substrate is passed in a continuous motion between two discharge elements between which a high voltage potential is produced sufficient to arc a gap between the discharge elements and burrs on the edges of the substrate. A shaped discharge surface is provided to ensure arcing to burrs having a variety of orientations. The arcing voltage and current are controlled to provide power to erode and remove the burrs. The current and frequency of the power supply providing the arcing current are selected and controlled to distribute the deburring energy over the length of the substrate. By so doing, deburring is accomplished with minimized damage to the substrate and without producing additional burrs. Preferably, the frequency of the discharging current at least matches the frequency of the burrs passing the discharge elements. This is particularly applicable in deburring substrates made from foam or porous metals such as the nickel foams used in many secondary electrochemical cells. These method adapt well to commercial production of electrochemical cells in that the electrodes may be deburred quickly and easily. Due to the noncontacting nature of the deburring process, movement of the electrodes through a typical deburring device need not be carried out with great precision. An example device is provided which uses an inexpensive and easily obtained power transformer as a discharge power supply.

Title: The use of 4-H-1-benzopyran-4-one derivatives as inhibitors of smooth muscle cell proliferation
Inventor: PATTERSON WINSTON CAMPBELL
IPC: C07D405/04
Filed: 2000-01-25
Granted: 2007-02-21
Abstract: Smooth muscle cell (SMC) proliferation is a critical component of neointimal formation in many animal models of vascular injury, and in many human lesions as well. Cell cycle inhibition by gene transfer techniques can block SMC proliferation and lesion formation in many animal models, although these methods are not yet applicable to the treatment of human disease. Flavopiridol is a recently identified, potent, orally available cyclin-dependent kinase inhibitor. Given the role of smooth muscle cell (SMC) proliferation in vascular disease, we tested the effects of flavopiridol, a recently identified cyclin-dependent kinase inhibitor, on SMC growth in vitro and in vivo. Flavopiridol (75 nmol/L) potently blocked SMC proliferation, an effect that was associated with downregulation of cyclin-dependent kinase activity and cell cycle-related gene expression. We examined the effects of flavopiridol on SMC proliferation in vivo in the rat carotid injury model. Flavopiridol (5 mg/kg) decreased neointimal size by 35% and 39% at 7 and 14 days, respectively, after balloon injury. Flavopiridol may be a potential therapeutic tool in the treatment of SMC-rich vascular lesions. 4-H-1-benzopyran-4-one derivatives inhibit smooth muscle cell proliferation at low dosage levels.

Granted: 2001-01-11
Abstract: A rodless cylinder is coupled to an elongated base. The construction for coupling the rodless cylinder to the base includes a hollow duct formed in the bottom wall of the base and extending along the entire length of the base. A projection extending along the entire length of the duct is formed on the upper inner wall of the duct when the base and duct are formed by a drawing or extrusion process. After the base is formed, the longitudinal ends of the projection are cut off by a predetermined length from both longitudinal ends of the base. The portions of the duct from which the projections are cut off act as receiving portions into which mounting nuts are inserted, and the end faces of the remaining projection act as stoppers which abut the inserted mounting nuts to position them. The upper walls of the duct above the receiving portions are cut off to from slits opening to the upper face of the base. The slits act as mounting bolt passage of the rodless cylinder. The rodless cylinder is coupled to the base by inserting mounting bolts through bolt holes on end caps disposed on both ends of the cylinder. The bolts further pass through the slits and engage the mounting nuts placed in the receiving portions. By tightening the mounting bolts, the rodless cylinder is firmly coupled to the base.
