Title: Methods and apparatus for downlink diversity in cdma using walsh codes
Inventor: BUEHRER R MICHAEL
IPC: H04J11/00
Filed: 2000-04-10
Abstract: Downlink diversity in a CDMA system is provided by employing Walsh codes in conjunction with M transmit antennas at a common base station serving K  mobiles, where M may or may not be to equal to K. The present invention provides methods and apparatus for improving downlink diversity in a CDMA system. Each transmit antenna transmits a signal representing the result of the modulation of Walsh codes by data signals for each of the K mobiles, assuming there is data pertaining to a particular mobile.  The assignment of Walsh codes is accomplished in accordance with a transmission matrix T. The transmission matrix maps the user data symbols onto the Walsh codes for each antenna and is preferably designed such that its columns are representative of the transmit antennas and orthogonal. Thus, at a given mobile, the mobile need only correlate with M different Walsh codes since each transmit signal received contains a component that is the result of M different Walsh codes having been modulated by a data signal associated with that particular mobile. The set of Walsh codes to select from includes 2[log2(K)] Walsh codes. However, with respect to any given mobile, there is needed only as many different Walsh codes as there are transmit antennas serving the particular mobile. The results of the respective M correlations are combined and, with obtained channel estimates, the receiver estimates the particular data pertaining to that particular mobile so that it can be provided to the user. Also, the present invention provides for various ways to estimate the respective channels between the M  transmit antennas and a mobile. It is to be appreciated that the downlink diversity techniques of the invention may be applied to the physical layer proposed in the IS95-C  physical layer draft proposal.

Title: Process for preparing a high purity chemical-free microcrystalline cellulose from a chemically produced cellulose
Inventor: JOLLEZ PAUL
IPC: D21C9/00
Filed: 1998-05-14
Abstract: A high purity chemical-free microcrystalline cellulose having a low degree od polymerization can be obtained by a process that does not require the use of any acids such as HCl, H2SO4 as are needed in conventional acid hydrolysis processes. This process comprises the steps of preparing a pulp by repulping, filtration and trituration of a chemically produced cellulose. The so-prepared pulp is subjected to heating through a steam explosion treatment in order to obtain a treated pulp. A shearing force is applied onto the pulp at the end of the steam treatment. The treated pulp is then filtered, washed and bleached thereby to obtain the high purity chemical-free microcrystalline cellulose.  With this process, one may produce chemical free microcrystalline cellulose by using chemically produced cellulose such as kraft or bisulfite cellulose as starting material. The high purity microcrystalline cellulose obtained from the present process may be used in the pharmaceutical and nutritional industries.

IPC: B30B15/14
Filed: 2001-01-09
Abstract: With a method of controlling synchronous drive of a plurality of pressing machines, each of the pressing machines has a motor, a drive shaft to which a torque of a flywheel driven by the motor is transmitted through a clutch and a slide driven by the drive shaft so that a rotational position of the drive shaft of each of the pressing machines is synchronous each other.        The method has a step of detecting actual velocity information of the motor and a step of detecting actual rotational-position information of the drive shaft. The detected actual rotational-position information is compared with the reference rotational-position information from a reference rotational position information generating section. Based on the result of the comparison, the reference velocity information from a reference velocity information generating section is compensated into characteristic reference velocity information of each of the pressing machines. The motor is controllably driven based on the characteristic reference velocity information and the actual velocity information.
