Title: Inverter device
Inventor: HIGA OSAMU
IPC: H02M7/48
Filed: 1978-04-10
Abstract: PURPOSE: To prevent an overvoltage from being generated, during turn-off time when in a main switching operation, by an inductance component of the load, also to heighten a utilization factor of the elements.  
     CONSTITUTION: With a main switching element 21 conducted, a current flows through a DC power source 10, a reactor 11, center point of the primary winding of a transformer 12, one end of the transformer 12 and the main switching element 21, causing a secondary winding of the transformer 12 to induce a current, with a power fed to a load 13. With the main switching element 21 made in no conduction and an auxiliary swtiching element 20 in conduction, the current, having been flowing in the reactor 11, is made circulating in the loop routed through the reactor 11, the neutral point of the transformer 12, a diode 201 and the auxiliary switching element 20. Accordingly, under the above condition, with the main switching element 21 even made in no conduction, the current, flowing in the inductance of the load 13, is never to be cut off, with a generation of overvoltage not caused.

Title: Isdn terminal adapter device
Inventor: IDA SHUJI
IPC: H04Q3/42
Filed: 1995-03-01
Abstract: PURPOSE: To prevent remote control by a suspicious person by limiting a remote control of incoming call by the use of a password ID in an ISDN terminal adapter. CONSTITUTION: At the time of the incoming call from a remote terminal, a connection message is transmits to a network 101 from a call control part 5 and a call is once disconnected. Moreover, a call originator transmits the password ID which is registered in an ID registering part 11 from a transmitting part 10 by adding it to a call setting message. In an incoming call side device, an ID receiving part 9 takes out the password ID from the received message, compares it with a self ID which is set in the ID registering part 11, connects the call at the time of coincidence and changes-over communication data path from 1) to 2). At the time of noncoincidence, the call is disconnected.

Title: Method and device for controlling sequential process
Inventor: KUBOTA HIROSHI
IPC: G06F11/30
Filed: 1999-02-19
Abstract: PROBLEM TO BE SOLVED: To relieve the load on a CPU and then to improve the processing performance as a result by allowing a process monitor means to monitor the result of a 1st processing means as preprocessing and judges whether or not a 2nd processing means is executed according to the confirmation contents. SOLUTION: The process monitor means 22 which detects the process result when the 1st process means 21 is executed is not actuated at the same with the 1st processing means 212, namely, only the 1st processing means 21 is executed. Then when the 2nd processing means 23 is executed, the process monitor means 22 is executed to confirm the result of the 1st processing means 21 as preprocessing. According to the confirmation contents, it is judged whether or not the 2nd processing means 23 is executed. Thus, the process monitor means 22 which detects the process end of the 1st processing means 21 is not always executed, but executed when the 2nd processing means 23 is executed to monitor the result of the 1st processing means 21, so the load on the CPU of a data processor is relieved.
