Filed: 1995-10-18
Abstract: PROBLEM TO BE SOLVED: To attain a sufficient dust-proof effect through a relatively simple structure by forming an annular protrusion oppositely to a shield on a position regulating member for the inner ring of a bearing through a specified gap. SOLUTION: An annular protrusion 2b is formed, through a micro gap, on the base 2 serving as a position regulating member for the inner ring 4a2 oppositely to a shield 4a1 extending from the outer ring 4a3 to the inner ring 4a2 side. The annular protrusion 2b formed on the base 2 provides a pair of annular recesses 2a, 2b which define a space. When a rotator 5 rotates in a specific direction together with a disc, an air flow is generated in one recess 2a and the inner and outer rings of bearing are shielded thus preventing scattering of dusts. Similarly, the recess 2C functions to generate an air flow thus providing a singificant effect for preventing scattering of dusts. According to the invention, the dust seal effect for grease and the like can be enhanced through a simple structure.

Title: Mobile communication terminal
Inventor: SATOU TAKAAKI
IPC: H04W36/18
Filed: 1996-10-18
Abstract: PROBLEM TO BE SOLVED: To detect the change of receiving quality of peripheral cells and to instruct the soft handover to a mobile communication terminal by adding a receiving level measurement means to the mobile communication terminal to measure the receiving level of the signal received in a receiving band before the adverse diffusion in addition to a peripheral cell search constitution. SOLUTION: A mobile communication station acquires the spread code information which is used by peripheral cells and stores it in a spread code storage means 14. A peripheral cell search control means 15 sets a cell search execution cycle Δt1 and a receiving level measurement execution cycle Δt2 to the timers T1 and T2 respectively. When the timer T2 counts up its counting, the means 15 instructs a receiving level measurement means 17 to measure the receiving level and decides the value of RSSI change of a signal included in a receiving band based on the measurement result of the means 17. If the RSSI change is large, the spread codes which are used by the peripheral cells stored in the means 14 are successively set to a sequential inverse spread means 12. Then a receiving quality measurement means 13 measures the SIR received from every peripheral cell.
