Abstract: The present invention provides a cermet coating that can take advantage of the hardness of a powder for a hard reinforcement phase more effectively, and spraying particles for forming the cermet coating. The cermet coating is formed on a base surface and has a hard reinforcement phase and a binder phase. The cermet coating has a Vickers hardness of from 50% to less than 100% of the hardness of the powder for a hard reinforcement phase, and has a surface roughness (center-line average roughness Ra) of less than 3.0. The cermet coating is formed by heating spraying particles prepared as aggregates of a powder for a hard reinforcement phase and a powder for a binder phase, and applying the spraying particles to a base at a supersonic velocity to integrate the powder for a hard reinforcement phase with the powder for a binder phase.
Abstract: Disclosed is a thermal spray powder of granulated and sintered cermet particles. The granulated and sintered cermet particles have an average particle size of 5 to 25 ?m. The particles have a compressive strength of 50 MPa or higher. The particles have a straight ratio of 0.25 or higher, the straight ratio being defined as a value resulting from dividing the maximum thickness of a thermal spray coating obtained, when 150 grams of the thermal spray powder is subjected to thermal spot spraying, by the length of the longest of line segments each of which has both ends thereof on a contour of the spray coating. The granulated and sintered cermet particles have an average aspect ratio of preferably 1.25 or lower. The thermal spray powder is preferably used in applications where a thermal spray coating is formed by high-velocity flame spraying or cold spraying.
Abstract: A driving maneuver assisting apparatus includes a learning section configured to learn a driving-behavior pattern of a driver for a predetermined duration; a non-steady-state degree calculating section configured to calculate a non-steady-state degree by comparing a current driving-behavior pattern with the driving-behavior pattern learned by the learning section, wherein the non-steady-state degree represents how different the current driving-behavior pattern is from the driving-behavior pattern learned by the learning section; a learning level calculating section configured to calculate a learning level of the learning section; and a notifying section configured to notify the driver of a maneuver assisting information for inducing the driving-behavior pattern learned by the learning section in accordance with the learning level calculated by the learning level calculating section, when the non-steady-state degree calculated by the non-steady-state degree calculating section exceeds a threshold value.
Abstract: A vehicle driving assist apparatus includes an input section to sense a vehicle traveling condition of a vehicle, an output section to present assist information to a driver of the vehicle, and a control section to prepare the assist information in accordance with the vehicle traveling condition sensed by the sensing section. The control section is configured to determine an estimation quantity (such as a driver's receptivity or a driver's responsiveness to the assist information, or a driver's driving behavior), and to adjust the assist information in accordance with the estimation quantity. The control section may be further configured to determine a presentation mode in accordance with the estimation quantity, and to present the assist information through the output section to the driver in the presentation mode.

Abstract: A vibration reducing device, including an inertial mass actuator adapted to be mounted on a vibration damping object, that applies a vibration damping force on the vibration damping object, the vibration damping force being a reactive force generated due to displacement of an inertial mass. A vibration state detector detects the vibration state of the inertial mass. A controller is connected to the inertial mass actuator and vibration state detector. The controller determines the displacement and velocity of the vibration damping object at a part where the inertial mass actuator is mounted, and the displacement and velocity of the inertial mass, based on the vibration state of the inertial mass. The vibration damping force is controlled based on the determined displacement and velocity of the vibration damping object at the part where the inertial mass actuator is mounted, and the displacement and velocity of the inertial mass.

Abstract: A stereoscopic image display system has a left/right stereoscopic image signal generator for alternately generating left-eye and right-eye image signals at every field, a screen for projecting image light, a liquid crystal shutter. The liquid crystal shutter has a response speed of 1 ms or less, and a contrast between black and white of 100 to 1 or more at a central wavelength of an emission spectrum of a CRT in both parallel and crossing modes of the polarizing plates of the shutter, and a cell gap of 3 .mu.m or less. The screen comprises a Fresnel lens and a lenticular sheet, and the lenticular sheet is disposed in a direction so that a polarizing condition does not generate a phase difference based on the lenticular sheet.
