Title: Demodulator eliminates quadrature error
Inventor: IEMURA TAKAYA
IPC: H03D3/00
Filed: 2000-01-25
Abstract: A demodulator for signal (IF IN) which has been quadrature modulated includes a quasi-coherent detection section (1, 2, 3, 4, 5, 6), a demodulation section (7, 8, 9, 11, 16), a signal error detector (14), a phase error detector (12), a quadrature error detector (17) and a quadrature controller (15). The signal error detector (14) detects signal errors (Ei, Eq) and polarities (Di, Dq) of demodulated signals (I-ch5, Q-ch5). The detector (12) detects the phase error (Pd) of the demodulated signals (I-ch5, Q-ch5) based on signal errors (Ei, Eq) and polarities (Di, Dq). In the quadrature error detector (17), a quadrature error (Qd') after phase rotation executed in the demodulation section (7, 8, 9, 11, 16) is obtained by calculating Ei   Ò   Dq + Eq   Ò   Di, and thereafter a quadrature error (Qd) before the phase rotation is obtained by means of polarity switching based on the demodulated signals (I-ch5, Q-ch5) and a phase rotation angle signal (Ang) which is generated from the phase error (Pd). The quadrature controller (15) executes complex multiplication to quadrature components (I-ch1, Q-ch1) obtained by the quasi-coherent detection section (1, 2, 3, 4, 5, 6) based on the quadrature error (Qd), and thereby the quadrature error in the demodulated signals (I-ch5, Q-ch5) is eliminated.

Title: Rack-and-pinion gearing in an electric power steering apparatus
Inventor: SHIMIZU YASUO
IPC: F16H57/12
Filed: 2000-10-06
Abstract: An electric power steering apparatus has a motor for producing assist torque according to the steering torque and a rack and pinion mechanism for transferring torque assistance to the rack shaft. The pinion (33) and rack  34) of the rack and pinion mechanism are both helical gears with a curved arc tooth profile.

Title: Methods and System for Using Caches
Inventor: GRABINAR PAUL LIONEL
IPC: G06F17/30
Filed: 2002-05-29
Abstract: A method of communicating data objects, across a data communication network, between a cache (210) and a request server (225), operably coupled to a data store (230), in a remote information system (240). The method includes the steps of assembling at least one business object by the request server (225) from data in held in the data store (230) and storing a corresponding business object in the cache (210). A business object update is communicated between the cache (210) and the request server (225) to update data held in the data store (230) or the cache (210), wherein the business object update substantially comprises only one or more change to said data. Furthermore, the cache stores at least one business object comprising a plurality of data objects as one retrievable entity. In this manner, all business logic may be removed from an application and a cache, thereby making them easier to implement and increase the portability between the cache (210) and different data stores (130). Additionally, an improved cache management communications protocol removes the need for an application to recover from network problems, thereby making the application easier to write. Transactional integrity is also improved.
