Title: Pad bearing
Inventor: HISA SHIYOUICHI
IPC: F16C33/00
Filed: 1978-05-24
Abstract: PURPOSE: To enable a self-adjustment of a pad in the case of a high load operation as a result of forming a lubricating oil film at a back surface of the pad, by connecting together an oil storage part at a back surface of a bearing pad and an inner circumferential surface of the pad.  
     CONSTITUTION: An oil storage part 9 is formed at a central portion of a back surface of a bearing pad 20. A lubricating oil on each bearing pad 20 flows into the oil storage part 9 at the back surface passing through a connecting hole 11 due to a difference in the pressure between an inner surface of the bearing pad 20 and a back surface. An oil pressure being equivalent to the pressure of a lubricating oil film formed at the inner surface of the bearing pad is produced at the oil storage part 9 due to a squeeze effect provided between the back surface of the bearing pad 20 and the inner circumferential surface of a bearing outer ring 1, and each bearing pad 20 can freely and slidably move as a result of floating up slightly. And thus, the pad moves in the circumferential direction corresponding to the movement of a rotation shaft 3, and its position can be self-adjusted so that a compound pressure of the lubricating oil film will be dicided at a most suitable value corresponding to a load of the rotation shaft 3.

Title: Adaptive filter and interference elimination system using the adaptive filter
Inventor: OTA SHINJI
IPC: H04B1/7097
Filed: 1994-03-08
Abstract: PURPOSE:To improving the converging speed of an adaptive filter, to reduce the time loss caused by the relearning and also to improve the transmitting efficiency by deciding the initial value of the filter coefficient based on the mutual correlation between the spreading code of the user in charge of an input node and the spreading code of the user in charge of an output node. CONSTITUTION:When the calculated and estimated mutual correlation value 091 is equal to the mutual correlation value decided by the precedent learning, an adaptive filter control part 07 informs a memory part 10 of the output timing. Then the corresponding matched filter output value 041 are simultaneously inputted to each input node of an adaptive filter. If the value 091 is different from the mutual correlation value of the precedent learning, the value 091 is sent to an adaptive filter initial value generating part 08. Thus the part 08 decides the initial value of the filter coefficient based on the spreading code of the user in charge of an input node and the spreading code of the user in charge of an output node.
