IPC: B41J2/30
Filed: 1987-06-29
Abstract: PURPOSE:To surely prevent the overheating of a printing head by detecting an individual voltage of a current flowing in each head coil. CONSTITUTION:When electricity is supplied considerably frequently to a specific head coil 8, the temperatures of the specific head coil 8 are gradually raised, with increasing the resistance value.

Abstract: PROBLEM TO BE SOLVED: To improve operability and maintenance in order to improve the reliability of a radio communication system against its partial failure by securing the automatic operation of another normal base station or base station controller when a specific base station or base station controller failes or stops its operation for maintenance. SOLUTION: When a base station 91, for example, discontinues its operation, a base station controller 7 detects this abnormality and a mobile communication exchange 1 recognizes the abnormality. When the operation of the station 91 is discontinued, the exchange 1 recognizes the base stations 81, 93, 84 and 82 which are adjacent to and complement the station 91 and obtains the complemental output data on every adjacent station in the abnormal state. Then the exchange 1 outputs these complemental output data to those stations 81 to 82 in radio waves via the base station controllers 6 and 7 and by the output of a designated level of the exchange 1. As a result, the service area of the faulty station 91 can be covered with no deterioration overall quality of the system, i.e., with prevention of the mutual interference.

Title: Signal transmitting method in cdma mobile communication system, mobile station device and base station device
Inventor: KAMIBAYASHI SHINJI
IPC: H04J13/00
Filed: 1996-06-20
Abstract: PROBLEM TO BE SOLVED: To provide a CDMA(code division multiple access) mobile communication system where a delay time till communication is established is short without transmission by excess power. SOLUTION: The transmission requesting signals RQ1, RQ2, RQ3,... of respective mobile stations, which are received by a common channel, only control the transmission power of an open loop so that control difference is large and the fluctuation of a reception level is also large. But reception power is a degree of 1/a in terms of an average as compared with communication signals MSG1, MSG2, MSG3,... so that interference quantity to the communication signals are suppressed to be low. The communication signals are transmitted in accordance with a transmission power control bit which is included in an outgoing signal ACK from a base station. After that, the transmission power of a closed loop is controlled so that the fluctuation of the reception level in the base station is suppressed to be low.  When the transmission power of the closed loop is controlled even during the transmission of an incoming signal RQ, interference quantity is, moreover, reduced. At this time, it is also adequate that a transmission power control signal is not included in the outgoing signal ACK from the base station.
