Title: Timer
Inventor: MURASE AKIRA
IPC: H01H43/00
Filed: 1987-10-15
Abstract: PURPOSE:To exactly execute a timer operation under the condition of a very low temperature by executing a turn on/turn off control of a control object circuit by utilizing a variation of a critical current density or critical temperature of an oxide super conductor in terms of the lapse of time. CONSTITUTION:When a current is allowed to flow to a time element 1 by adjusting to the current density which has been set by a variable resistor 5, while holding the time element 1 at a temperature being lower enough than a critical temperature of an oxide superconductor which has been used, in this case, since the time element 1 is a superconductive state, the conversion value is zero, therefore, a current from a constant-voltage power source 3 flows between an input use terminal 2 and an output use terminal, and from a control use terminal 4, current does not flow due to the resistor 5, and a control object circuit becomes turned off state. As time elapses, the critical current density of the oxide superconductor decreases and instantaneously it is transferred to a normal conductive state, and the time element 1 becomes a very large resistor. Subsequently, a current from a power source 6 flows to the control object circuit from the control use terminal 4, and the control object circuit is turned on.
