    • A marine radar transmission and reception system in which first and second transmission pulse radar waves are emitted as first and second pulse radar waves from first and second radar antennae or a common radar antenna; reflected waves of the first and second emitted pulse radar waves are received as first and second received pulse radar waves by the first and second radar antennae or the common radar antenna; the modes of the first and second transmission pulse radar waves are selected in cooperation with those of the first and second radar antennae or that of the common radar antenna so that the first and second received pulse radar waves may be received by the first and second radar antennae or the common radar antenna independently of each other; a quotient or difference output corresponding to the quotient or difference of the first and second received pulse radar waves or the first and second received outputs based thereon is obtained; and sea clutter eliminated received pulse radar waves or outputs based thereon that signal components of the period--in which the quotient or difference output exceeds one predetermined threshold value or lies between two threshold values--are eliminated or suppressed, are obtained.

    • In a fixing device, when sheets of small width size are continuously passed and temperature rises in both side parts, a temperature control unit stops print control of an auxiliary lamp. When the temperature rise in both side parts continues after that, a drive control unit shifts the fixing device to a wait mode and pre-runs the fixing device. Moreover, in a low-temperature environment, when temperature rises in both side parts when sheets Ps of small width size are continuously passed, the temperature control unit switches temperature control of the fixing device to three-stage control.
