Abstract: The invention provides a mobile communication system capable of swiftly performing handover involved in the change of wireless communication area in the minimum switching time required. Each of the base stations acquires from other base stations the traffic channel information of peripheral base stations in order to specify a user specific channel (USC) that can be used for the communication with the mobile station, and sends this traffic channel information to the mobile station located within its local wireless communication area by use of a slow associated control channel of its local traffic channel. The mobile station detects the receiving level of signal from the base station with which it is currently communicating. When the communication status is deteriorated, it switches to the USC of another base station on the basis of the traffic channel information of the peripheral base stations sent from the base station, and continues to communicate.

Abstract: An ink jet recording system for recording using a recording head which discharges heated ink onto a recording medium through discharge ports includes temperature detection of ink discharged through the discharge ports, position of the recording head so that a temperature of ink discharged through the discharge ports can be detected, detection of discharge or non-discharge of ink based on the temperature detection, variation of discharge of ink droplets, and control of the variation during discharge detection.

Abstract: If one page of recording is terminated, a carriage moves to a position at which a recording head is located opposite a cap. Then, the ink is discharged through nozzles of the recording head onto temperature detecting element within the cap. Temperature change of the temperature detecting element upon contact with the ink is output from a detecting circuit, and the normal discharge of ink is detected by discharge detecting means. In this way, the decrease in the ink remain or the detection of ink undischarge can be securely made.

Abstract: An image processor includes a first write device which serially inputs each of plural kinds of color component data for each pixel, and writes each color component data into a first line buffer for each line. A second write device reads in a unit of a line for each color component data written in the first line buffer, and writes each color component data corresponding to the plural lines into a second line buffer having a storage capacity which is larger than that of the first line buffer. A conversion device performs longitudinal-to-lateral conversion by using each color component data corresponding to the plural lines written in the second buffer. An output device serially outputs a visible image representing each color component data corresponding to the plural lines converted by the conversion device.
