Abstract: PURPOSE: To prevent high-temperature steam from flowing into a steam condenser by providing a circuit for retaining a damp steam temperature control valve at a constant opening for a fixed period of time in advance when the change rate of the operation output of a flush tank pressure control valve reaches a specified value or higher. CONSTITUTION: A damp steam temperature control valve 18 constitutes a circuit for performing a switching operation via a selector 25 with a signal that is obtained by performing an operation, using a PI operator 23, to a deviation being obtained by performing an operation to a signal from a temperature detector 17 and that from temperature-setting equipment 21 using a subtractor 22 and a setting value from a control output setting equipment 24.  Not only when a flush tank pressure control valve 15 opens from a completely closed state but also when pressure control is made and at the same time when an opening operation is started from a current opening, the opening operation of the flush tank pressure control valve 15 is detected from the change rate of operation output, the damp steam temperature control valve 18 is retained at a constant opening before detecting temperature increase due to the increase in the amount of steams flowing into a steam condenser, thus supplying a constant amount of water to temperature-reducing equipment and hence preventing a high-temperature steam from flowing to the steam condenser.

Title: Carrier synchronizing system
Inventor: SUDO SHIGEYUKI
IPC: H04L27/22
Filed: 1990-09-21
Abstract: PURPOSE:To reduce the influence of a phase jump and to improve estimation precision by constituting a system by means of a loop consisting of a data reference means, a first offset estimation means, a first phase correction means, a modulation component removal means, a second phase correction means and a second offset estimation means. CONSTITUTION:The first offset estimation means removes a modulation component from a reception sample list in a training period with stored data of the data reference means as a reference, extracts rotational amounts in one symbol period by a fixed frequency deviation including noise, averages them and removes a noise component. The first phase correction means corrects a phase based on the estimation of the first offset estimation means. At that time, an initial phase difference is preserved in the phases of respective reception samples. The loop constituted by the modulation component removal means, the second offset estimation means and the second phase correction means estimates two offset parameters of the remaining fixed frequency deviation and the initial phase so as to execute correction. Correction is asymptotic and it is converged within an error with which the fixed frequency deviation is acknowledged from the repetitive condition of the loop.
