Filed: 1980-09-30
Abstract: PURPOSE:To make fine voltage regulation possible while number of taps of a transformer and number of switches are reduced, by a method wherein a transformer is composed by connecting a main winding and a pluraity of supplement windings in series and semiconductor switches are inserted between those windings. CONSTITUTION:Two interim taps in addition to both end taps are provided to a supplement winding 2 at an interval of 1V and semiconductor switches 4 are connected to the terminals 5-8 of the supplement winding 2. Also the terminals 9-12 are provided to a main winding 1 at an interval of 1,000V and the switches 4 are connected to those terminals. The terminals 8 and 9 are connected to output terminals 13 and 14 respectively. Input terminals 15 and 16 are provided to an input winding 17 which corresponds to the windings 1 and 2. With above configuration when a specified voltage is applied between the terminals 15 and 16 and only the switches 4 of the terminals 8 and 9 are on the voltage between the terminals 13 and 14 becomes zero. In the same way, many voltage values can be obtained in such a manner that on-setting of the terminals 7 and 9 gives 1V between the terminals 13 and 14, on-setting of 6 and 9 gives 2V, 5 and 9 3V, 8 and 10 1,000V, 5 and 12 15V, and so forth.

Title: Vector processor
Inventor: SAKATA KUNIHIKO
IPC: G06F15/78
Filed: 1983-07-25
Abstract: PURPOSE:To store the element trains of all arithmetic results to a main memory with generation of an arithmetic error by inhibiting generation of an interruption of arithmetic error when said interruption is produced. CONSTITUTION:When an arithmetic error is produced, a microprogram control part 15 sets an FF22 to close an AND gate 21. This inhibits to deliver an arithmetic error signal ERROR to the part 15 as an arithmetic error interruption signal INT. As a result, no arithmetic error interruption is produced and the operation is continued regardless of the arithmetic error signal given from an operator. When the operation is through with all elements, the arithmetic results so far written to a vector register are shifted to a main memory. Therefore the approximate value is set in an arithmetic error mode with a cumulative operation, for example, and therefore the final result is relieved.
