Abstract: A method for automatically optimizing cell placement on a chip using many processors. In the method, the chip is divided into first regions along a first direction. In each first region, a cell is moved in only one direction, which is perpendicular to the first direction. This operation for each first region is executed at the same time by each processor. After an evaluation function is calculated for each first region, the optimized evaluated value for each first region is stored in a memory in each processor. Next, the chip is divided into second regions along a second direction which is vertical to the first direction. The second regions are moved in only one direction which is perpendicular to the second direction. In the same manner that the first regions are processed, the second regions are similarly processed. Thus, an optimizing cell placement can be obtained.

Abstract: An electrical power system protection device includes a circuit breaker and a switch connected in series to a power line. The protection device also has a current limiting element connected in parallel to the circuit breaker. When the level of electrical current flowing in the power line, detected by a current detector, has exceeded a predetermined first set level, a first over-current detector delivers immediately a trip command to the circuit breaker. As a consequence, fault current is commutated to the current limiting element so that any drop of voltage in the power line upstream of the circuit breaker is greatly suppressed. When a state in which a predetermined second set level is exceeded by the detected current level is continued beyond a predetermined period, a second over-current detector delivers an off command to the switch, thus protecting the upstream portion of the power line against the fault in this power line.

Abstract: An air-mix door control apparatus for an air conditioner of an automobile wherein an opening range of the air-mix door divides into three ranges on the basis of the relationship between the change ratio of opening of the air-mix door and the change ratio of the discharge air temperature. In the range where the change ratio of the discharge air temperature is great, the voltage applied to the air-mix control motor is changed over to a low voltage, in the range where the change ratio of the discharge air temperature is small, the voltage applied to the air-mix control motor is changed over to a high voltage. In the range where the change ratio of the discharge air temperature with respect to the change of opening of the air-mix door is great, changing of the air-mix door can be prevented. In the range where the change ratio of discharge air temperature with respect to the change of opening of the air-mix door is small, the responsiveness of the air-mix door can be improved.
