Filed: 1994-09-16
Abstract: PURPOSE: To obtain a constant-current generating circuit device of very simple constitution and low manufacturing cost by providing a power supply circuit for applying a specified voltage across both ends of wire rod consisting of a high-temperature oxide superconducting ceramic material. CONSTITUTION: An incubator RL and a wire rod 1 consisting of GdBa2 Cu3 O7-8 ceramic material, which is one of high--temperature oxide superconducting ceramics, are connected to an electric circuit EC where a power supply is E. When a voltage, which is higher than a specified voltage, is applied on the wire rod 1, a local Joule red heat point 2 appears. When this point 2 is red- heated to 400 deg.C or higher, the resistance at this point is increased owing to the occurrence of the loss of oxygen. The voltage applied on the red heat point 2 is increased by an increase in resistance. Therefore, the constant current can be generated. That is to say, the constant-current generating circuit device of a very simple constitution and a low manufacturing cost, can be achieved.

Title: Timer circuit
Inventor: SANO YUJI
IPC: H03K17/28
Filed: 1988-09-07
Abstract: PURPOSE:To obtain a timer with long delay time by connecting another one terminal short-circuited alternately to two terminals of a switch to one external terminal, and connecting an output terminal not being connected to the terminal of the switch to another external terminal in a circuit consisting of an active element and a switch terminal. CONSTITUTION:When the switch is switched to an off side and the terminals 7 and 8 are short-circuited, incidental capacitance among the terminals of the gate, drain, and source of the active element 2 is charged via a diode 3. Next, when the switch is switched to an on side, the terminals 6 and 7 are short-circuited, and the source terminal of the element 2 is connected to the external terminal 5 of a timer circuit, and the diode 3 is cut off by the impression of a voltage in a backward direction. At this time, an electric charge accumulated in the incidental capacitance is discharged by a leakage current that flows from the output terminal of the element 2 to the gate terminal and the leakage current that flows from the cathode of the diode 3 in a direction of anode. When the voltage between the gate and the source goes less than a pinch-off voltage, an energized state between the drain and the source is generated. In such a way, it is possible to control the voltage between the external terminal by the element by a timer operation.
