Title: Structure of supplying oil of rotary compressor
Inventor: GU CHI UK
IPC: F04C29/00
Filed: 1998-12-24
Abstract: PURPOSE: A rotary compressor is provided to perform compression smoothly by installing an oil pipe supplying oil between inner walls of a roller and a cylinder. CONSTITUTION: After power is fed to a motor assembly(315), a rotary shaft(317) starts to rotate by the electromagnetic interaction of a stator and a rotor(319). One end of the rotary shaft is installed and an eccentric part(322) installed in a cylinder(332) starts to rotate. By the rotation of the eccentric part, a roller(330) rotates. The roller is combined to the eccentric part integrally and thus the roller rotates eccentrically. The inner part of the cylinder is divided into two parts of suction and ventilation by the roller. While the roller rotates, the suction part becomes in a low pressure state. The oil stored in an oil tank(309) is sucked into an oil channel(356) and supplied to a gap(354) between the inner walls of the roller and the cylinder by passing through a muffler(358), an oil storage part(352) and the oil channel. By the oil, the roller smoothly contacts to the inner wall of the cylinder.

Abstract: PURPOSE: A channel hopping device for mobile stations and a base station is provided to solve the problem of how channels shall be allocated to the different connections between a base station and mobile stations that are located within the area covered by the base station. CONSTITUTION: A channel allocation(211) within the base station (BS1) generates channel hopping sequences that are transmitted via a control channel (SACCH) to hopping sequence lists(204-206) in the mobile stations (MS1-MS3). The hopping sequences are also transmitted to corresponding hopping sequence lists(201-203) in the base station (BS1). A channel hopping sequence is divided into a number of sequence intervals corresponding to the time between two adjacent channel hops within a channel hopping sequence. In the channel allocation(211) the attenuation of the connections (F1-F3) and the interference of the channels are continuously being observed within each sequence interval. The channel allocation(211) generates channel hopping sequences according to the principle that a connection that has poor connection quality will be allocated a channel hopping sequence with channels of high channel quality and connections with successively better connection quality are allocated channel hopping sequence having successively poorer channels.
