Title: Tap control system
Inventor: SUGANUMA ISAO
IPC: G05F1/14
Filed: 1987-03-20
Abstract: PURPOSE:To control tap switching even in transformers provided with no tap position detectors by the remote control, by determining the number of times of tap operation based on the measured value of the secondary voltage of a transformer to perform the tap operation. CONSTITUTION:A voltage detector 6 is provided on the secondary side of a transformer 1, and the value detected by this detector 6 is transmitted to a centralized supervisory and control equipment 6 through an information transmission equipment 4. An operation processing part 50 of the centralized supervisory and control equipment 5 obtains the difference between a target voltage value inputted by an operator and the current secondary voltage value of the transformer 1 and divides this difference value by a secondary voltage value per tap of the transformer 1 to obtain the number of times of tap operation. This obtained value is compared with a comparison value and a tap raising or lowering command is outputted in accordance with the comparison result. Thus, the tap control is possible in transformers provided with no tap position detectors.

Title: Automatic control system of disconnecting switch for substation feeding tie in electric railway
Inventor: NISHIMURA HIROMI
IPC: B60M3/00
Filed: 1983-04-15
Abstract: PURPOSE:To make a spare high-speed circuit breaker omissible, by opening the high-speed circuit breaker of a substation concerned and an adjoining substation on the basis of making-failure detection, while making a circuit for a tie disconnecting switch of the substation concerned under the reset condition of a voltage detector. CONSTITUTION:When a tie disconnecting switch 89D of a B substation is in a state of being opened and a high-speed circuit breaker 54F1 or 54F2 fails to make a circuit because of anything trouble, the substation gives an 'off' command to its own 54F1 or 54F2 as well as to these 54F4 and 54F1 of both A and C substations. And, when each of them all is opened, each of feeder lines Fe1 and Fe2 comes to no voltage whereby voltage relays 184 and 484 are reset and on condition of this, a control unit of the B substation gives an 'on' command to the tie disconnecting switch 89D, and when circuit making takes place, the 'off' command to each high-speed circuit breaker is released free, thus circuit making of the tie disconnecting switch 89D in the B substation is automatically completed. Doing like this, a spare high-speed circuit breaker falls into disuse and formation is made inexpensive, thus high reliability is securable.

Title: Frame synchronizing system
Inventor: KUDO NORIMASA
IPC: H04L7/08
Filed: 1987-03-20
Abstract: PURPOSE:To shorten a time required until a synchronism state is established by detecting a frame synchronizing pattern at each bit position of one frame, and performing transition at each detected bit position. CONSTITUTION:The detection of the frame synchronizing patterns FS-1-FS-4 are always performed at each bit position of incoming data, and the transition between the synchronism established state and a hunting state is performed at each detected bit position. And a frame timing signal is outputted at one bit position set at the synchronism established state, and also, when the bit position goes to the hunting state by the transition, the bit position being set at a state nearer to another synchronism established state is changed to the bit position from where a frame timing signal is outputted, thereby, the synchronism is taken. In such a way, it is possible to shorten the time until the synchronism can be obtained after pull-out is generated or in a case of erroneous synchronism.
