Abstract: PURPOSE:To operate independently an access mechanism by merely specifying a virtual access means and generating an access instruction by a host computer, and selecting an optimum physical access means by a controller in a mass storage system, and making the result correspond to the specified virtual access means. CONSTITUTION:Each host computer CPU when waiting for an access request sends an instruction for moving a data cartridge to a virtual access control mechanism and access mechanism ARC/ACC through a primary controller DIR0. Once this instruction is received, such a physical access mechanism that a processing time is shortest is selected according to the address of the cell containing the data cartridge, the address of a data recording mechanism DR which performs recording and reproduction, and the operation performance of current physical access mechanism to perform access. One primary controller DIR0 performs batch control over two physical access mechanisms ACC0 and ACC1 individually to make the best selection.

Abstract: PURPOSE:To prevent the occurrence of facets and to fill up an opening part flatly, by forming the opening part in an insulator layer so that a sidewall is provided along the direction within a specified angle range with respect to orientation <100> of a semiconductor single crystal, and growing a single crystal semiconductor layer in said opening part by a selective epitaxial growth method. CONSTITUTION:An insulator layer 2 is formed on the face (001) or on the main surface close to said surface of a semiconductor single crystal 1 directly or through a layer constituting a semiconductor circuit. Then, an opening part 3 reaching the semiconductor single crystal 1 is formed at the specified place of the insulator layer 2. The opening part 3 has a sidewall along the direction within a range of + or -5 deg. with respect to the orientation <100> of the semiconductor single crystal. Then, a single crystal semiconductor layer having the same crystal orientation as that of the semiconductor single crystal 1 is grown in the opening part 3 by a selective epitaxial growing method. Thus the step is not yielded at the interface between the single crystal semiconductor layer by the epitaxial growing in the opening part and the insulator layer. Therefore, the yield of a facet can be prevented.

Abstract: PROBLEM TO BE SOLVED: To accurately grasp a relation of working force and the operation of an occupant protective device after the fact by storing a parameter detection value showing an input state of working force on a vehicle when the parameter detection value reaches a second threshold which is lower than a threshold operating the occupant protective means. SOLUTION: A control unit 2 reads a vehicle state at every prescribed time interval, reads acceleration and judges whether the acceleration is a prescribed threshold or more or not.

Thus, data of a changed characteristic of a change of acceleration and prescribed information are stored by being related each other, and the operation of an occupant protection controller and influence on occupants can be traced after the fact.
