Title: Ac-dc converter
Inventor: ARAKAWA KOJI
IPC: H02M3/28
Filed: 1992-05-22
Abstract: PURPOSE:To improve a power factor and reduce the occurrence of voltage distortion or higher harmonics at power supply line without making a complicated circuit configuration and without increasing the shape. CONSTITUTION:A step-down type DC-DC converter 9 is connected to a rectifier 1 at the, input side, and an output current is of the rectifier 1 flows only in the time period when the output voltage V3 of the rectifier 1 is higher than the voltage V4 of an output capacitor C4 of DC-DC converter 9. By doing this, the power factor can be improved without using an active filter, and the occurrence of harmonics or voltage distortion of a power supply line can be reduced. Compared to the case of using the active filter, the shape of a choke coil of the input circuit can be reduced, and this is advantageous for reducing the shape of the AC-DC converter.

Title: Method for network management for packet exchange network management equipment
Inventor: IIZUKA MARIKO
IPC: H04L12/70
Filed: 1990-06-14
Abstract: PURPOSE:To continue management of a packet exchange located remote from a line fault location by setting a bypass network management path via a public telephone network in which a packet exchange is accommodated. CONSTITUTION:A public network automatic dial control means 13 dials a specific prescribed number for setting a bypass network management path. The specific number dial information is given to a non-protocol communication control means 14, from which the information is sent to a non-protocol PAD of a packet exchange 20 via a specific interface and a public telephone network 2. A non-protocol PAD 24 receiving the dial information for setting a bypass network management path accesses a station management means 21. When the station management means 21 is accessed via the non-protocol PAD 24 while the communication of a communication line 1 in its own network is interrupted, the communication control implemented through an X25 interface is replaced into the communication control of non-protocol interface. Thus, the operating state of a packet exchange 20-4 is monitored and controlled via a bypass network management path 8 set to a public telephone network 2.

Filed: 1992-06-16
Abstract: PURPOSE:To save labor for the change-over work of a blower by equally vary ing blow-off variable quantity of the blower in the waiting condition with the blower in the blasting condition. CONSTITUTION:A blow-off valve 36b in the blower in the waiting condition is once made to wholly open and from closing operational quantity of the blow- off valve 36b according to a prescribed signal, the blow-off variable quantity per unit signal is calculated. In the blower in the blasting condition, by using the blow-off characteristic curve C, the opening operational quantity of the blow-off valve equal to the blow-off variable quantity is obtd. By using the operational quantity as the reference, a time coming to the whole opening of the blow-off valve 36a in the blower in the blasting condition is obtd. Based on this time, the opening/closing operations of the blow-off valves 36a, 36b in both blowers are executed at the same time and the blow-off variable quantities of both blowers are equally varied. In such a way, by changing over from the blower in the blasting condition to the blower in the waiting condition, the blasting of the blower in the waiting condition is started. By this method, working load of the operator can drastically be reduced.
