Abstract: A model creation device 11 includes a replacement information obtaining unit 111 that obtains replacement part information for identifying a replaced part of a vehicle, replacement date information indicating the date when the part was replaced, and vehicle identification information for identifying the vehicle, a first data obtaining unit 112 that obtains a measured data set including a plurality of measured data obtained by measuring the state of a vehicle from a plurality of vehicles in association with the vehicle identification information, and a model creation unit 114 that creates a failure prediction model by using the plurality of measured data included in a measured data set obtained from a vehicle having a problem in the result of the executed self-diagnosis as training data for failure occurrence, among the plurality of measured data sets corresponding to the plurality of pieces of vehicle identification information obtained by the replacement information obtaining unit 111.

Abstract: An unlock system does not use a key that might be copied so that only a correct person can unlock a door and security is enhanced. Unlock records of door-lock are stored in a limited memory capacity in volume. Fingerprint data input to a fingerprint input section 21 disposed outside a door 11 provided on a doorway 10 is detected, and the detected fingerprint data is verified against previously registered fingerprint data. If it was confirmed that the detected fingerprint data coincided with the registered fingerprint data, an unlock signal is output to unlock the door-lock. At the same time, an identification code of the registered fingerprint data that unlocked is stored.

Abstract: A first hemming mold unit (20) and a second hemming mold unit (30), are installed in a single pressing machine. The first hemming mold unit (20) performs partial bending of an edge (95) of a workpiece (93; 96). The workpiece (93; 96), having undergone the partial bending, is transferred to the second hemming mold unit (30), the second hemming mold unit (30) performs remaining necessary bending of the edge of the workpiece (93; 96). Here, predetermined bending of the edge (95) of the workpiece (93; 96) can be completed within the single pressing machine only by downward movement of upper molds (24, 34) of the first and second hemming mold units (20, 30), without having to use a cam and cam driver.

Abstract: A forming press apparatus with which forming of a plurality of different workpieces can be carried out using a single press. The press has raise/lowerable upper and lower die sets. A plurality of forming die pairs corresponding to a plurality of forming steps to be carried out on a pre-drawn workpiece are mounted en bloc to the die sets. The forming die pairs are disposed in a row on the die sets in the order of the forming steps.

Abstract: A resinous die for press-shaping a blank material into a desired configuration, which comprises a die member and a mating punch, both having respective shaping portions. Each shaping portion is formed of an epoxy resin layer provided at portions thereof where a relatively low surface pressure is applied, and a plurality of reinforcing pieces provided in an embedded fashion at portions thereof where a relatively high surface pressure is applied, for reinforcing the shaping portion. This arrangement imparts increased durability to the shaping portion and hence the die while keeping the cost of manufacture of the die to a minimum.

Abstract: A cutting edge is formed by build-up welding on a die of a die assembly made of a base material of an aluminum/copper-based zinc alloy. The cutting edge comprises an underlying layer and an overlying layer. The underlying layer is made of a copper alloy that can be welded to both a zinc alloy and a nickel alloy, and the overlying layer is made of a nickel alloy. The cutting edge is of high machinability, high durability, and high hardness.

Abstract: A cylinder head structure for an engine, including grooves (18; 12a) in a top surface (2; 2a) of a cylinder head body (1; 1a) such that they surround an associated a fuel injection nozzle hole (11; 8a). Valve tappet guide holes (6; 3a) are also formed in the top surface (2; 2a) of the cylinder head body (1; 1a) around each of the fuel injection nozzle holes (11; 8a). The grooves (18; 12a) connect the adjacent tappet guide holes (6; 3a) and surround the associated nozzle or spark plug hole. Cylinder head bolt holes (15; 9a) are also formed around the tappet guide holes (6; 3a). When cylinder head bolts are tightened to join the cylinder head with a cylinder block, a radiant tension (F) is generated from the cylinder head bolt heads which are in contact with the cylinder head top surface. This radiant tension would cause cracking around the injection nozzle hole (11; 8a).

Abstract: A method and apparatus for fingerprint recognition is provided in accordance with the present invention to achieve a higher rate of recognition by subsequently storing fingerprint patterns with higher rates of correspondence in place of fingerprint patterns already stored having low rates of correspondence.
