Title: Method for separating hydrogen gas
Inventor: SUMIDA TOSHIHIKO
IPC: B01D53/04
Filed: 2001-12-25
Granted: 2007-08-01
Abstract: Product gas (Gpro) is separated from material gas (Gmat) by a PSA process utilizing a plurality of adsorption towers (A-C) each loaded with an adsorbent. The separation of the product gas (Gpro) is performed by repeating a cycle comprising an adsorption step, a decompression step, a desorption step, a cleaning step and a pressurization step. In the decompression step, remaining gas (Grem) as cleaning gas is introduced from one adsorption tower (C) to another adsorption tower (B). The amount of the remaining gas (Grem) introduced is 2 to 7 times the volume of the adsorbent loaded in the adsorption tower (B) as converted into volume at common temperature and under atmospheric pressure. To remove both of carbon monoxide and carbon dioxide from the material gas (Gmat) by a single kind of adsorbent, use is made of zeolite having a faujasite structure with a Si/Al ratio lying in a range of 1 to 1.5 and a lithium-exchange ratio of no less than 95%.

Title: Self-correlation detection and in-band and out-of-band signal detection for automatic gain calibration systems
Inventor: HUSTED PAUL
IPC: H03G5/16
Filed: 2002-04-16
Granted: 2004-02-21
Abstract: An embodiment of the present invention provides an automatic gain control system for a wireless receiver that quickly differentiates desired in-band signals from high power out-of-band signals that overlap into the target band. The system measures power before and after passing a received signal through a pair of finite impulse response filters that largely restrict the signal's power to that which is in-band. By comparing the in-band energy of the received signal after filtering to the total signal energy prior to filtering, it is possible to determine whether a new in-band signal has arrived. The presence of this new in-band signal is then verified by a multi-threshold comparison of the normalized self-correlation to verify the presence of a new, desired in-band signal.

Title: Semiconductor device
Inventor: TOMITA KAZUO
IPC: H01L23/31
Filed: 2003-04-02
Granted: 2004-11-21
Abstract: It is intended to prevent a crack from occurring in a circuit region during dicing, while preventing oxidation and corrosion of a seal ring including a layer of copper as the uppermost layer thereof. A passivation film (120) has an opening (123) formed therein, The opening (123) is formed so as to reach an interlayer insulating film (109) and disposed so as to surround a periphery of a seal ring (110). As a result, a top face of a second interconnect layer (114) is completely covered by the passivation film (120), and is not exposed to an ambient air. Hence, it is possible to prevent an effect of protecting a semiconductor device achieved by the seal ring (110) from being reduced due to oxidation and corrosion of the second interconnect layer (114). Further, provision of the opening (123) does not allow a stress generated at a time of cutting a dicing region during dicing to easily propagate to a portion of the passivation film (120) present on the circuit region. This prevents occurrence of a crack in the circuit region.
