Abstract: In a magnetic head suspension, a main body region of a flexure substrate is fixed to a load beam part at plural welding points including F/L first and second welding points respectively arranged on distal and proximal sides of a position of a LB bending that reduces a gain of a torsion vibration of the load beam part. In a case where a length of a flat region in the suspension longitudinal direction is represented by F, the flat region extending between an end position on the distal side of the bending at the LB bending position and the F/L first welding point is represented by F, and a length between the F/L first welding point and a supporting arm welding point is represented by D, a condition of 0.02?F/D?0.05 is met.

Abstract: The vehicle control apparatus gives a control current to the electromagnetic control valve at a start of energization of the electromagnetic control valve as a start current value smaller by a first determined amount than an open/closed state change-over reference current value which is necessary for changing over a state of the electromagnetic valve and after the start of energization of the electromagnetic control valve, the control current gradually increases with a smaller increase inclination than an increase inclination of an increase control of the control current which gives priority to a control responsibility of the electromagnetic control valve and finishes a gradual increase of the control current applying to the electromagnetic control valve, when the control current exceeds a finish current value which is larger than the open/closed state change-over reference current value.
