Abstract: A household electric appliance and a household electric system are provided which are capable of quickly responding to the electric power demand in which the peak cut of the power consumption is requested. The household electric appliance comprises: a receiving unit that receives a request for a peak cut of power consumption at a predetermined rate from a remote controller and a mobile terminal; a drive unit that drives a power-consuming object to be driven; and a control unit that controls an action of the drive unit. The control unit, in the case of reception of the peak cut request from the remote controller or the mobile terminal, controls the action of the drive unit so as to cut a maximum value of the power consumption within the appliance based on the requested rate.

Abstract: To enable signal position detection, frequency offset compensation, clock offset compensation, and chromatic dispersion amount estimation in a communication system based on coherent detection using an optical signal, even on a signal having a great offset in an arrival time depending on a frequency due to chromatic dispersion. An optical signal transmitting apparatus generates specific frequency band signals having power concentrated on two or more specific frequencies and transmits a signal including the specific frequency band signals. An optical signal receiving apparatus converts a received signal into a digital signal, detects positions of the specific frequency band signals from the converted digital signal, estimates frequency positions of the detected specific frequency band signals, and detects a frequency offset between an optical signal receiving apparatus and an optical signal transmitting apparatus.

Abstract: A technical problem of this invention especially in the case of large-size bottles is to form a grip, without changing the bottle shape to a large extent, so that the body can be firmly held. The object of this invention is to provide a synthetic resin square bottle that can be used reliably because the bottle can be held firmly with a hand. A major means of solving the problem is a synthetic resin square bottle comprising a body having a rectangular shape in a plane cross-section and a groove-like waist portion disposed at a middle height of the bottle, wherein a pair of recessed portions for use as finger stops are formed in respective long side walls of said rectangular body over a predetermined area ranging from said waist portion downward to ensure that a plural number of fingers can be placed in at least one recessed portion for a finger stop purpose, and wherein a grip for holding the bottle is formed from both the pair of recessed portions and the waist portion.
