摘要:
A sliding structure including first and second sliding elements made of metal and including first and second sliding surfaces relatively slidable via a lubricating oil film therebetween, in which at least one of the first and second sliding surfaces having a microscopic surface structure including a base portion, dimples inward recessed from the base portion and separated from one another, and a peripheral portion defining the opening area of each of the dimples and extending along a periphery of each of the dimples. A ratio of a sum of opening areas of the dimples to an area of the at least one of the first and second surfaces is in a range of 5% to 60%. The peripheral portion has a height smaller than a thickness of the lubricating oil film.
摘要:
A rotary assembly for traction drives, including a plurality of rolling elements having a rotation axis and traction contact surfaces around the rotation axis and associating with each other to transmit a motive power between the rolling elements via a traction oil film formed between the traction contact surfaces, in which at least one of the traction contact surfaces has a microstructure with irregularities which sizes are larger than a thickness of the traction oil film. The process for the traction contact surface is also disclosed.

A function for compensating an error between a teacher signal and an output signal with a weight value is defined. A multilayered neural network is changed so that the function becomes minimum. Thus, the multilayered neural network can be adaptively controlled.

A sliding member is produced by forming hardening layers with two-layered structure on surface of a substrate metal with a Vickers hardness of not more than Hv300, such as aluminum or magnesium alloy for example, and then forming a DLC film having surface roughness defined as maximum height roughness Rz of 1 to 10 μm further on the hardening layers. The above-described hardening layers are composed of a first hardening layer dispersed with heavy metal particles, preferably made of tungsten and/or tantalum in the substrate metal, and a second hardening layer formed under the first hardening layer.

A low-friction sliding mechanism includes first and second sliding members having respective sliding surfaces slidable relative to each other and a lubricant applied to the sliding surfaces of the first and second sliding members. At least the sliding surface of the first sliding member is made of a diamond-like carbon material, and at least the sliding surface of the second sliding member is made of either an aluminum-based alloy material, a magnesium-based alloy material or a diamond-like carbon material. The lubricant contains a base oil and at least one of an ashless fatty-ester friction modifier and an ashless aliphatic-amine friction modifier.

A computer implemented method and a computer system implementing the method of a business process transformation wizard leads a business analyst through a series of steps to invoke business transformation patterns, in order to analyze the results of those processes. The wizard first prompts the business analyst to specify business objectives of process transformation. Required parameters are added to the business process model guided by the business process transformation wizard until the business process model is completed. Once the model is completed, the wizard prompts the business analyst to select transformation techniques or patterns for optimizing process parameters and, for each selected transformation pattern, optimizes process parameters using a selected optimization technique. The wizard also prompts the business analyst to select transformation patterns for optimizing topology of the business process and, for each selected transformation pattern, optimizes topology for the business process using a selected optimization technique.

摘要:
A transition metal nitride comprises a first layer formed of a nitride of a stainless steel containing at least Fe and Cr and a second layer formed on the first layer and having an exposed surface. The second layer is formed of another nitride having contents of components that differ from those in the first layer. The first and second layers have a composition distribution in which a Cr concentration is continuously changed from the first layer to the second layer in a thickness direction of these layers, and the second layer has a nitride deposition protruding from a base portion of an exposed surface. A fuel cell separator comprises a base layer formed of a stainless steel containing at least Fe and Cr and a nitride layer formed of a transition metal nitride as described. Methods of forming transition metal nitrides and fuel cell separators are also included, as is a fuel cell vehicle including a fuel cell stack.
