Title: Rolling bearing
Inventor: HATABU SHIYOUJI
IPC: F16C33/44
Filed: 1989-09-30
Abstract: PURPOSE:To form a transfer film of high polymer resin solid lubricant on the surface of a rolling element to lengthen the service life of a bearing by particularly specifying average coarseness of a center line on the surface of the rolling element. CONSTITUTION:By setting average coarseness of a center line on the surface of a rolling element to 0.01mum or more less than 1.01mum, which is coarser than conventional, high polymer resin solid lubricant as a material of a holder is scratched macroscopically by the rolling element and is made easy to physically attach to the rolling element, resulting in formation of a transfer film of the high polymer resin solid lubricant on the surface to secure a good sliding state. By making the surface of the rolling element coarse, deterioration in a service life and an increase in vibration acceleration are suspected, but a state of lubrication is improved and the average coarseness of the center line is set to less than 1.01mum, so that a bearing service life is extended in this range as well as there is no practical problem with respect to the vibration acceleration.

Title: Recording and reproducing device
Inventor: NAKAMURA MASAFUMI
IPC: G11B15/473
Filed: 1987-10-14
Abstract: PURPOSE:To perform control to keep relative velocity constant by reproducing a signal surely at a time when an area goes to the one on which the signal is recorded by setting large relative speed between a tape and a magnetic head in the area where no signal is recorded on the tape. CONSTITUTION:When an operation is started in the area where no signal is recorded on the tape 3, it is decided that no recording signal exists by a recording signal detecting means 8, and the rotating speed of rotary heads 2A and 2B are controlled so that the relative speed of the rotary heads 2A and 2B can be set higher than a constant value for the feed speed of the tape by a rotation control means 22. Therefore, when the heads enters the area where the signal is recorded, a signal level to be reproduced from the differential characteristic of the head is increased due to the high relative speed between the tape and the head. In such a way, it is possible to surely reproduce the recording signal.

Abstract: PURPOSE:To reduce the number of elements by adding delay time at a part of all the input terminals of logic elements constituting a logic circuit to the delay time of the logic element in a preceding step to drive the respective input terminals and executing simulation while replacing the delay of the input terminal added the delay time to the preceding step with zero. CONSTITUTION:The delay time at one part of all the input terminals of logic elements 1 and 4 constituting the logic circuit is added to the delay time of the logic element 1 in the preceding step to drive the respective input terminals, and the simulation is executed while replacing the delay of the input terminal IN added the delay time to the preceding step with zero. For example, delay elements 2 and 3 having propagation delay time d1 and d2 are inserted to the input terminal side of the logic element 4, and this delay element 2 is driven by the logic element 1 having propagation delay time (t). Next, the delay time of the logic element 1 in the preceding step is set to (t+d1) and the delay time of the delay element 2 is turned to zero. Thus, by executing the logic simulation in the state of omitting the delay element 2, the number of elements is reduced and counting time required for the simulation can be shortened.
