An electric toothbrush wherein the number of revolution of a motor shaft is in match with the frequency of reciprocating motion of the brush. A motor () housed in a tubular case () is coupled to a reciprocating shaft () slidably extending through the forward end of the case by a scotch yoke mechanism () for converting one turn of rotation of the motor shaft () into one stroke of reciprocating pivotal movement of a pivotal body (), and by motion conversion means () for converting one stroke of reciprocating movement of the pivotal body () into one stroke of linear reciprocating motion of the reciprocating shaft ().

A heat pump type air conditioner having a heat gas engine having a radiator and a cooler, an outdoor heat exchanger provided in an outdoor unit and an indoor heat exchanger provided in an indoor unit, is further provided with a heat exchanger in the outdoor unit and/or the indoor unit, and control means for controlling water flow in first and second passages so as to perform cooling/heating operation. When slightly-heating or slightly-cooling dry operation or defrosting operation is required, a part of the hot water from the radiator is allowed to selectively flow through the second fluid passage into the heat exchanger by adjusting opening degree of open/close valves disposed between the first and second fluid passages.

Gas displacement volumes of a high temperature chamber and a middle temperature chamber in a high temperature portion of a hot gas machine are different. Alternatively, a gas displacement volume of a low temperature chamber and a middle temperature chamber in a low temperature portion are different.
