Title: Optical disc copy management system
Inventor: BLAUKOVITSCH REINHARD HERMANN
IPC: G09C1/00
Filed: 1998-06-30
Granted: 1999-11-21
Abstract: The invention relates to a method of obtaining a copy protected optical record carrier carrying information in different blocks, a method of accessing such a copy protected optical record carrier and such an optical record carrier itself. Access means for optical record carriers return different results when retrieving blocks, which contain incorrect address data in the corresponding subcode fields, A copy protection key will be implemented during manufacture of an optical record carrier by modifying the subcode address information of a predetermined pattern of blocks. It is normally not possible to copy incorrect address data onto an optical record carrier, since the address data will be newly generated during the copy process. Therefore, such a key can be utilized to distinguish between an original disc and a copied or non original disc. The key is preset before manufacturing of the optical record carrier itself and can therefore be used to encrypt the data stored on the optical record carrier. Upon accessing of the data, first the key is extracted from the optical record carrier and then the data can be decrypted utilizing this key.

Granted: 2002-05-21
Abstract: To provide a gas adsorber with the gas and moisture removing capacity kept high even when the air to be treated is at a high temperature and without the consumption of energy being remarkably increased. This adsorber is provided with a gas adsorption part having a gas adsorbing rotor for adsorbing the gas in the air to be treated, a treated air zone 6 and a regenerated air zone 7 for discharging the adsorbed gas. Water is sprayed to a gas stream to form a liquid-gas mixed stream containing foggy fine water droplets, the mixed gas stream passes through one passage of a heat exchanger 13 and the air to be cooled passes through another passage, and hence the sensible heat is exchanged between the mixed gas stream and the air to be treated while they pass through passages of the heat exchanger 13. Consequently, the water droplets in the mixed gas stream are vaporized as it is heated, the mixed gas stream is continuously cooled by the heat of vaporization, the air is also continuously cooled through the heat exchanger 13 in a cooling part, and the cooled air passing through the heat exchanger 13 is sent to the treated air zone 6.

Title: Small caliber non-toxic penetrator projectile
Inventor: HALVERSON HENRY J
IPC: F42B12/74
Filed: 1998-10-03
Granted: 2000-01-21
Abstract: A small caliber non-toxic penetrator projectile has a first core and a second core tandemly aligned and enveloped by a jacket. The first core has a hardness great than the hardness of the second core that has a Brinell hardness of between about 20 and about 50. The hardness of the second core is significantly higher than the hardness of lead and when the first core strikes a target, the second core resists compressive bulging. As a result, more kinetic energy is transferred to the first core rather than diffused along the surfaces of an armored target. The more efficient transfer of kinetic enables the use of lower density second cores, such as annealed copper.

Title: Cache architecture to enable accurate cache sensitivity
Inventor: FRANKE HUBERTUS
IPC: G06F12/08
Filed: 1999-05-28
Granted: 2002-11-01
Abstract: A technique of monitoring the cache footprint of relevant threads on a given processor and its associated cache, thus enabling operating systems to perform better cache sensitive scheduling. A function of the footprint of a thread in a cache can be used as an indication of the affinity of that thread to that cache's processor. For instance, the larger the number of cachelines already existing in a cache, the smaller the number of cache misses the thread will experience when scheduled on that processor, and hence the greater the affinity of the thread to that processor. Besides a thread's priority and other system defined parameters, scheduling algorithms can take cache affinity into account when assigning execution of threads to particular processors. This invention describes an apparatus that accurately measures the cache footprint of a thread on a given processor and its associated cache by keeping a state and ownership count of cachelines based on ownership registration and a cache usage as determined by a cache monitoring unit.

Title: Semiconductor memory device and method of manufacturing same
Inventor: NODA KENJI
IPC: H01L27/092
Filed: 2000-03-16
Granted: 2002-09-21
Abstract: A plurality of p wells and a plurality of n wells are formed in a p-type semiconductor substrate having a memory portion and a peripheral circuit portion. Next, a resist pattern is formed on the semiconductor substrate. The resist pattern has apertures which, as viewed from the direction normal to the plane of the semiconductor substrate, approximately coincide with the p wells, wherein the area of aperture openings on the top side of the resist pattern is different from the area of aperture openings on the bottom side of the resist pattern. By using the resist pattern as a mask, p-type ions are injected in a shape approximately the same as that of the aperture opening on the top side or bottom side, whichever has the smaller area. Thereafter, by using the same resist pattern as a mask, n-type ions having enough energy to pass through resist of a predetermined thickness are injected into the p-type semiconductor substrate through areas, located adjacent the apertures in the resist pattern, in which the effective thickness of the resist is small, thereby forming deep n wells so as to cover the p well regions.

Title: Method for fabricating an integrated circuit capacitor
Inventor: LEE KI-YOUNG
IPC: H01L21/02
Filed: 2000-04-17
Granted: 2001-08-21
Abstract: A method for fabricating a MIM capacitor of a MDL logic or analog circuit of a semiconductor device. A conductivity layer is formed on a semiconductor substrate having a first inter-level insulating layer. A capping metal layer having an etching rate higher than an oxide layer is formed on the conductivity layer. A lower electrode comprising a ""conductivity layer/capping metal layer"" deposition is formed by selectively etching the capping metal layer and the conductivity layer in order to expose a predetermined part of the surface of the first inter-level insulating layer. A second inter-level insulating layer is formed on the first inter-level insulating layer covering the lower electrode. A via hole is formed by selectively etching both the second inter-level insulating layer and the lower electrode thereby to expose a portion of the lower electrode so that a tapered capping metal layer remains along the lower edges of the via hole. A dielectric layer, devoid of step coverage defects and concentrated electric fields, is inserted in the via hole between the lower and upper electrodes thereby preventing current leakage and short circuits at portions of the dielectric layer. This has the beneficial effect of substantially improving product yield and reliability.
