Title: Gto parallel connection
Inventor: SENDA KATSUNORI
IPC: H02M7/521
Filed: 1990-07-04
Abstract: PURPOSE:To reduce a current imbalance at the transient time of a parallel connection by forming not the direct parallel connection of GTO itself but a circuit, in which even the inner structure of a load is made parallel, because a GTO parallel connection is subject to the strict restriction that static and transient characteristics of respective GTOs must almost coincide with each other. CONSTITUTION:GTOs 5a, 5b are connected by a direct gate connecting line 11 and direct cathode connecting line 12, connected with a gate-driving circuit 7 from the middle point of these connecting lines and put in an ON-OFF control action by one gate-driving circuit 7. To reduce a current imbalance at a transient time, the direct gate and cathode connecting lines 11 and 12 have a powerful effect but are subject to the restriction that it is necessary to use the GTOs 5a, 5b having static and transient characteristics being within a certain range. In this case, however, more emphasis is placed on the dependence of impedance of the winding of a load 6 than on the characteristics of the GTOs 5a, 5b. When the impedances of the wiring of the load 6 and that to the load are equal relative to the GTOs 5a, 5b, it is possible to combine the GTOs regardless of the characteristics of the GTOs 5a, 5b.

Filed: 1991-07-16
Abstract: PURPOSE:To check a memory error in an image memory. CONSTITUTION:Data D1 written in the memory are compared with data D2 read out from the memory in each bit (S2 to S4). When both the data are not matched (S5), an evaluation value C obtained by adding respective weight coefficients W0 to W7 corresponding to respective bits is compared with a threshold B for subjective evaluation (S6, S7). When the C is larger than the B (S7), the address concerned is registered in an error table (S8). After checking all addresses (S9), the error addresses in the error table are successively read out (S11) and a block consisting of nine picture elements x nine picture elements around each error address is set up (S12). The degree of approach of each error address to another error address in the block is evaluated (S14), and when an evaluation value ER exceeds a threshold Z (S15), the center error address is disabled from being used.
