Abstract: A method that utilizes signals from an accelerometer in resonant frequency bands or high frequency bands to, in a cost-effective manner, measure wear particle penetration of lubricant and lubricant degradation, both of which greatly affect prediction of residual service life; and, using as a basis these measurements of wear particle penetration and lubricant degradation, enables accurate estimation of residual service life for rolling bearings in the early stages.

Abstract: Degradation of the lubricant due to contamination of the lubricant with wear particles or moisture, which greatly affects the service life of rolling bearings, can be detected in a cost-effective manner through the use of a resonance frequency band signal or high-frequency signal of an accelerometer, and the service life of a rolling bearing can be estimated with high precision at an early stage on the basis of the detected state of the wear particles and lubricant.

Abstract: A customer support system for improving the skill of a person engaged in a business with reduced cost for technical training support and enhancing practical training. The customer support system includes a computer system for introducing training contents from a service providing side to a customer side through a computer network; an instructor training facility for training an instructor based on training contents; and a remote technique training support device for the instructor, for supporting technical training on the customer side, from the service providing side, through the computer network.

Abstract: A system for preparing an administration plan using a computer, includes an inputting function, a risk calculating function, an optimizing function, and an outputting function. The optimizing function prepares the administration plan by optimizing and adjusting distribution between investment levels in investment items and the risk levels for a planning term.

Abstract: A customer support system for improving the technique of a person engaged in business is intended to reduce the cost for a technical training support and to enhance the training effect. The customer support system is constructed to comprise: a computer system for introducing training contents from a service providing side to a customer side through a computer network; an instructor training facility for training an instructor on the basis of the training contents; and a remote technique training support device for the instructor, for supporting the technical training of the customer side from the service providing side through the computer network.

Abstract: A production plan and a planning work to run resources for productions are so independent as to make it difficult to make an optimum administration plan as the entire enterprise activities. In a system for making an administration plan by a computer, an administration planning system comprises an inputting function, a risk calculating function, an optimizing function and an outputting function. The optimizing function makes the administration plan by optimizing and adjusting the distribution between the investment levels to plural investment item and the risk levels for a planning term.

Abstract: Synthetic fibrous structures having a soft feel, an excellent luster and a silky feel are produced by forming composite filaments composed of a polyamide and a component having poor affinity to the polyamide selected from the group consisting of a polyester, polyolefin and polyacrylonitrile into a fibrous structure and treating the fibrous structure with an aqueous emulsion of 1.5-50% by weight of at least one of benzyl alcohol and phenylethyl alcohol and having a percent transmittancy of less than 20%, which is obtained by adding a surfactant to the emulsion, whereby to fibrillate the composite filaments.
