Abstract: A multilayer ceramic capacitor includes a multilayer body including laminated ceramic layers, first and second principal surfaces in a height direction, first and second lateral surfaces in a width direction, and first and second end surfaces in a length direction, first and second internal electrode layers on the ceramic layers and respectively exposed to the first and second end surfaces, first and second external electrodes respectively electrically connected to the first and second internal electrode layers, and portions of the first and second principal surfaces and the first and second lateral surfaces. The first and second external electrodes each include an underlying electrode layer including a metal component, a plating layer on the underlying electrode layer, and a fatty acid on at least a surface of the underlying electrode layer.

Abstract: A portable telephone communications system has a portable telephone terminal (300) and a repeater unit (100), and a remote receiver unit (200), wherein the repeater unit (100) includes a main power supply control device which includes detection means triggered by a signal from the telephone terminal arising on receipt of an incoming call, and including infra-red transmission means for transmitting the signal as a frequency-modulated signal to the remote receiver unit; the remote receiver unit (200) includes an infra-red receptor, demodulation means (205) and means for outputting the demodulated signals as audible voice signals, and further comprises a noise level comparator (209d) which compares the voltage of noise generated when no infra-red signals are received with a predetermined level and delivers an output signal when said voltage exceeds the predetermined level, and a time counter (210) which outputs a reset signal when the output from the noise comparator has been generated for a predetermined time i
