Title: Hold circuit
Inventor: NORO MASAO
IPC: H03G3/20
Filed: 1989-04-28
Abstract: PURPOSE:To prevent a hold value from being changed due to the lapse of time by providing a rectifier means, a smoothing means, a capacitor to which the output of the smoothing means is supplied via a first rectifier element, and a second rectifier element connected in parallel with the first rectifier element also in a reverse direction, and taking out the output from the capacitor. CONSTITUTION:The output of the smoothing means 24 is supplied to the capacitor C3 via the first rectifier element D4, and is outputted as the hold value. When the output of the smoothing means 24 is decreased gradually by its time constant and it is decreased less than a value in which the voltage in forward direction of the second rectifier element D5 is subtracted from the voltage of the capacitor C3, the second rectifier element D5 is turned on, and the capacitor C3 is discharged to the smoothing means 24 via the second rectifier element D5. However, since the output of the smoothing means 24 reaches the value in which the voltage in forward direction of the first rectifier element D4 is added on the voltage of the capacitor C3 at an initial stage, no discharge of the capacitor C3 occurs until the output of the smoothing means 24 is decreased by the value in which the voltage in forward direction of the first rectifier element D4 is added on the voltage in the forward direction of the second rectifier element D5, then, the hold value can be held. In such a way, it is possible to prevent the hold value from being reduced.
