Abstract: A memory system that generates a reference voltage unaffected by supply voltage variations and is suitable for performing burn-in test is attainable by employing the following configuration. For example, in an MRAM containing a TMR element (Rij) and an N channel MOS transistor (Mij), as memory element, there is disposed a switching circuit (SW1) capable of switching between the state of applying a reference voltage (VrefN) to a memory element and the state of applying a reference voltage (VrefB) for burn-in test having a larger value than the reference voltage (VrefN) to the memory element. At the time of burn-in test, instead of the reference voltage (VrefN) for normal read operation, the reference voltage (VrefB) for burn-in test can be applied via a sense circuit (SC) to the memory element, by applying mode change signals (MODE1 to MODEn) from the exterior and operating the switching circuit (SW1) via a decode circuit (TD).

Abstract: A method for preparing a manufacturing plan for a manufacturing factory having multiple equipments and charged with multiple processes. The equipment is assigned to the processes to determine an operation pattern for a day. A load of each process is allotted among the equipment assigned to the process. Total load of each equipment is calculated by summing the allotted load. A capability index of each equipment is determined by dividing capacity of the equipment by the total load of the equipment. The capability index is multiplied by the allotted load to provide a feasible load of the equipment for the process. By summing the feasible load of each equipment, a total feasible load under the operation pattern is calculated for each process. By comparing the total feasible load with the load for each process, the operation pattern is determined whether acceptable or not.

Abstract: A failsafe support for use with a height adjustable passenger loading bridge. A main support member supports the weight of a passenger loading bridge passageway under normal operating conditions. The failsafe support includes a self-arresting mechanism for varying a length of a height-adjusting portion of the failsafe support in order to raise and lower a support portion of the failsafe support. The support portion is positionable adjacent to and spaced apart from a lower surface of the passenger loading bridge passageway, for supporting the weight of the passageway in the event of a failure of the main support member. The self-arresting mechanism prevents the passageway of the passenger loading bridge from descending to a level below the support portion.
