摘要:
The present invention provides a method for easily measuring a brake mean effective pressure of a running vehicle. An air flow sensor, a &lgr; sensor and a data collecting apparatus are mounted to the vehicle. A running speed and engine speed from the vehicle while actually running on a road surface, and output of the air flow sensor an the &lgr; sensor are inputted to the data collecting apparatus. Specific fuel consumption is obtained from an intake air amount and ratio of excessive air in exhaust gas. Output of an engine is obtained from a relation between the specific fuel consumption and the engine speed.

A magnetic disk apparatus of the present invention comprises a head slider with a magnetic head mounted thereon, a disk on which information is recorded/regenerated by the magnetic head, a spindle motor, integrally structured with the disk, for rotating the disk, a suspension for elastically supporting the magnetic head slider, a carriage arm for supporting the suspension and positioning the magnetic head, and a base plate for attaching the spindle motor and the carriage arm. An out-of-plane primary natural frequency of a base plate part to which the spindle is to be attached is set to be substantially the same as that of a base plate part to which the carriage arm is to be attached. An out-of-plane primary natural frequency of the carriage arm is detached from that of the base plate part to which the carriage arm is to be attached to such an extent that no resonance occurs. An out-of-plane primary natural frequency of the disk is detached from that of the base plate part to which the disk is to be attached to such an extent that no resonance occurs.

To suppress pressure fluctuation caused by insertion of arms between disks, which arms support thereon magnetic heads, to reduce disk flutter to thereby reduce disk driving power in a magnetic disk apparatus, there are provided an open space not covered by a shroud, which constitutes a part of a housing structure to cover a side surface of a disk stack, and provided on a downstream side of the arms relative to an airflow moving along surfaces of the disks as the disks rotate, and a channel, which connects a space on an upstream side of the arms and the open space not restricted by the shroud on the downstream side of the arms, the channel being provided with a linear section, which has a rectifying effect on the airflow.

Adhesive films may be vacuum laminated on a circuit substrate by sheeting an adhesive film having the same size as or a smaller size than that of a circuit substrate in a state wherein the surface of a resin composition in the adhesive film is allowed to provisionally partially adhere to one surface or both surfaces of the circuit substrate and disposing a protecting film having an area larger than that of the adhesive film on the adhesive film provisionally adhering to the circuit substrate so that the center of the protecting film is disposed at substantially the same position as that of the center of the adhesive film, followed by vacuum laminating under heating and pressing conditions.

A magnetic head slider assembly for a magnetic disk type recording/reproducing apparatus includes a slider body, a sliding pad provided on the slider body and projecting beyond a disk facing surface thereof, a thin film layer disposed at one end of the slider body, a magnetic head constituted by the thin film layer as an integral part thereof, and a core pad projection incorporating therein a core of the magnetic head and projecting beyond an adjacent disk facing surface of the slider body. The sliding pad is provided at a region of the slider body ahead of the core pad projection and prevents generation of a floating force by making use of a relative movement between the slider body and the magnetic disk. The core pad projection is not formed as a continuation of the slider body and is separated from the sliding pad a predetermined distance longitudinally of the slider body by a recess interposed therebetween whereby the core pad projection is positioned closer to the magnetic disk than a back end of the sliding pad.

A tomographic apparatus includes a movable radiation generating system and a movable radiation sensing system which may be placed independently of the location of the radiation generating system. The locus of movement of a radiation generating point is adjusted to be parallel to the arrangement of the radiation sensing system. The distance between the generating and sensing systems is obtained by a prescribed calculation. The CT scanning starts after initializing the radiation generating/sensing systems. Then, projecting data of the inspection object is obtained. Thereafter, image reconstruction processing is performed onto the obtained projection data in accordance with a sequential approximation method, so that a tomographic image of the object is produced. According to the above tomographic apparatus, since the movable radiation sensing system is independent of and optionally separated from the movable radiation generating system, it is possible to obtain the tomographic image of a large object, even if such an object cannot be moved and/or any obstructions exist around the object.
