IPC: F16H59/56
Filed: 2008-07-11
Abstract: <P>PROBLEM TO BE SOLVED: To prevent damaging of a related synchronous meshing mechanism, when pre-shift is forced while an oil quantity in a clutch makes the pre-shift difficult due to dragging of a release-side clutch.  <P>SOLUTION: In S1, a determination is made that a release-side automatic clutch is a released state of having no fastening capacity. Also in S3, when determining that an oil quantity Q in the releasing side automatic clutch read in S2 is a preset oil quantity Qs or more, since the release-side automatic clutch generates dragging torque for hindering the pre-shift via oil on the inside, the gear position setting for the pre-shift is prohibited in S4. In Q≥Qs, the release-side automatic clutch generates large dragging torque, and though there is risk of damaging the related synchronous meshing mechanism when forcing the pre-shift, this problem can be eliminated by prohibition of the pre-shift.  <P>COPYRIGHT: (C)2009,JPO&INPIT

Title: System of controlling transmission power rise in wireless cdma system by utilizing short codes
Inventor: OZLUTURK FATIH M
IPC: H04B1/707
Filed: 2008-07-22
Abstract: <P>PROBLEM TO BE SOLVED: To improve a method of controlling transmission power rise during a communication channel setting period between a subscriber unit and a base station in a wireless CDMA communication system.  <P>SOLUTION: The system and method for transmission power control during the channel setting period in the CDMA communication system utilize transmission of a short code from the subscriber unit to the base station when the initial transmission power increases. The short code is a code sequence for detection by the base station which has a much shorter period than a conventional spread code. The transmission power rise starts from a transmission power level that is guaranteed to be lower than the required transmission power level for detection by the base station. The subscriber unit quickly increases the transmission power while repeatedly transmitting the short code until the signal is detected by the base station. Once the base station detects the short code, the base station sends an instruction to the subscriber unit so as to stop the transmission power rise.  <P>COPYRIGHT: (C)2009,JPO&INPIT
