Abstract: Disclosed is a mobile communication system whereby, to reduce the connection time, a mobile station closely located to a base wireless station is permitted to continue to use a common channel for exchanging signals, and to suppress an increase in interference, an individual channel is set for a mobile station located near the edge of a cell, and to obtain a stabilized communication quality and to prevent an increase in the connection time, the probability that the transmission power will reach an upper limit is reduced. When communication between a mobile station and a wireless base station is started, the wireless base station measures the transmission power and the communication quality in the communication with the mobile station and the utilization ratio for a common channel, and compares the obtained values with predetermined threshold values. When the obtained values are lower than the threshold values, the wireless base station continues to use the common channel for signal transmission/reception.

Abstract: Pressurized fuel of a common rail is introduced into a control chamber of a fuel injector. An electromagnetic valve opens or closes a fuel discharge passage of the control chamber to adjust a hydraulic pressure of the control chamber. Through a switching leak passage, bubble-containing fuel directly returns from a valve opening of the electromagnetic valve to a low-pressure return passage without passing through an armature chamber. Through a stationary leak passage, the fuel leaking from every slide portion returns to the return passage via the armature chamber. A downstream portion of the stationary leak passage opens to the upper portion of the armature chamber. A damper element is provided downstream of the electromagnetic valve in the return passage for canceling an increased fuel pressure.
