A centrifugal separator facilitates maintenance with a function that provides the user with useful data for investigating the causes of failures and for preventing their recurrence, such as data needed to determine the appropriate management and replacement frequency of consumable parts. The centrifugal separator also has a storing unit for recording the number of times that the door is opened and closed, operation records of the drive unit by each shaft, and the number of operations performed by operating function, as well as a display unit for displaying the data. The centrifugal separator also includes a function for displaying messages prompting the user to perform maintenance when the aforementioned performance data reach a predetermined value.

A load sensor includes a optical fiber sensor that provides output analog signals in response to shocks of various magnitudes caused by hits by a vehicle on various objects, two or more amplifiers each of which approximates a non linear function of the analog signals and a unit that converts the linear functions into digital data. Therefore, each analog signal either in a lower magnitude range or a higher magnitude range can be amplified by one of the amplifiers that has a more suitable gain, so that the magnitude of the shock can be accurately converted into digital data for a pedestrian protection airbag system.

The present invention provides a semiconductor memory device capable of checking operation in the worst case in address combinations, and its manufacturing method. Specific data for test are written into a memory cell array 30. Then, a test signal TE1 is set “1” to set a device in a test mode. Refresh addresses for test are then stored in a data store circuit 51. A first address for test is applied to an address terminal 21, whereby a normal read or write operation is accomplished based on the first address for test. A second address for test is applied to the address terminal 21, whereby a refresh operation is accomplished based on the address for test, and subsequently another normal read or write operation is accomplished based on the second address for test. Data of the memory cell array 30 are checked to decide the presence or absence of any abnormality.

Refresh of memory cells is performed periodically by a refresh timer, and collision between memory access and memory refresh is avoided. When memory access occurs, an F/F 163 is set by a one shot pulse from an OS circuit 161, a memory access request is inputted to a memory accessing pulse generator circuit 171 through a NOR gate 167, and a latch control signal LC and an enable signal REN are outputted. When a refresh request from the refresh timer is inputted to an AND gate 168 during the memory access, the output of the NOR gate 167 is at the “L” level, and the refresh request is blocked by the AND gate 168. Thereafter, at the time when the latch control signal LC is turned into the “L” level, F/Fs 163, 164 and 165 are reset, the output of the NOR gate 167 is turned into the “H” level, the refresh request is inputted to a refreshing pulse generator circuit 170, and a refresh enable signal RERF is outputted.
