Abstract: An estimation apparatus includes: a vehicle type information storage unit for storing vehicle type identification information for identifying a vehicle type and component region information indicating a region of a vehicle component; and a processor that identifies the vehicle type based on input about an estimation target vehicle that is a target for which an estimate for repair is to be made, acquires the component region information corresponding to the vehicle type that is identified, receives input about a region corresponding to a position in the vehicle sample image as input of a damaged range, determines whether the region indicated by the component region information and the damaged range overlap each other, determines a vehicle component and repair details for the vehicle component based on the region, and calculates the estimated amount of money based on the vehicle component and the repair details for the vehicle component.

Abstract: A magnetic head has a main magnetic pole made of at least a magnetic material and a coil. The main magnetic pole has a stop layer through an inorganic insulating layer on both sides of the main magnetic pole in the widthwise direction. The boundary between the main magnetic pole and the metal layer becomes clear by the intervention of the inorganic insulating layer when viewing the flattened pattern plane by a scanning electron microscope and measuring the width of the main magnetic pole as a core width. The measurement accuracy of the main magnetic pole width can be improved and reductions in manufacturing yield rates which occur due to measurement errors can be prevented.

Abstract: The present invention relates to a magnetic thin film, which has high saturation magnetic flux density Bs of 2.2T or more, which is formed into a flat surface having surface roughness of 5 nm or less and which is capable of preferably being used for a write-head, and a magnetic head. The magnetic thin film includes a FeCo-based alloy layer stacked with a different layer so as to obtain the surface roughness of 5 nm or less. When forming the FeCo-based alloy layer, it is possible to flatten the film surface by performing reactive spattering using a reaction gas such as N2 for each of the layers forming the multi-layered thin film.

Abstract: A magnetic head manufacturing method including the steps of forming a recording lower magnetic pole and a recording upper magnetic pole on a substrate and trimming, by the ion milling method, a portion of the recording upper magnetic pole and the recording lower magnetic pole under the condition that the substrate is stationary.
