Inventor: HOSOKAWA TSUYOSHI
IPC: G01R31/24
Filed: 1987-12-12
Abstract: PURPOSE:To enable a withstand voltage test for the intermediate insertion electrodes of a cathode-ray tube by applying two types of the predetermined test voltage between the electrodes and detecting improper withstand voltage from a current value measured upon the application of low voltage and another current value measured upon the application of the test voltage. CONSTITUTION:The test of withstand voltage characteristics between the 6th grid electrode 7 and the 2nd intermediate electrode 9 is carried out in accordance with the following procedures. First, low voltage Eb1 in a region free from an improper withstand voltage symptom is applied and a measurement is taken of current Ir1 flowing at the low voltage side of a built-in partial resistor 10 and actually applied voltage V1. Then, the voltage is changed over to test voltage Eb2, and a measurement is taken of current Ir2 flowing at the low voltage side of the resistor 10 and actually applied voltage V2. And judgement as to whether withstand voltage is proper or not, is made using a criterion value equal to or less than Ir2-(Ir1XV2/V1), and the criterion value is kept, for example, approximately at 0.2 to 0.5muA. According to the aforesaid processes, it is possible to carry out the withstand voltage test for the intermediate electrode of a cathode-ray tube fitted with an electron gun of intermediate electrode insertion type.

Title: Rotary priority selection circuit of instruction execution sequence
Inventor: SUTEIIBUN EMERII RITSUCHI
IPC: G06F9/38
Filed: 1995-12-05
Abstract: PROBLEM TO BE SOLVED: To select the instruction to be executed next and, at the same time, to minimize the gate delay in a critical path in the design of a microprocessor which executes instructions in random order. SOLUTION: A priority logic circuit containing priority selecting modules 11-13 which select instructions in such a way that, when the execution wait instruction that is the oldest in time is executable (namely, has an operand), the modules 11-13 select the instruction as an instruction to be executed and, when the instruction is not executable, the next oldest executable instruction. The topology used in the logic circuit borrows the way of thinking of a high- speed parallel adder. The logic at each node in the circuit is equivalent to carry generating and propagating logic. A carry follows a loop and inhibits the input respond having the lowest priority. The loop is cut at a node designated from a pointer bus so that the carry is not fed back to the self loop. The number of gate delays in the circuit is reduced to the half of that in the conventional priority selecting circuit.
