Abstract: A dual stage scanning instrument includes a sensor for sensing a parameter of a sample and coarse and fine stages for causing relative motion between the sensor and the sample. The coarse stage has a resolution of about 1 micrometer and the fine stage has a resolution of 1 nanometer or better. The sensor is used to sense the parameter when both stages cause relative motion between the sensor assembly and the sample. The sensor may be used to sense height variations of the sample surface as well as thermal variations, electrostatic, magnetic, light reflectivity or light transmission parameters at the same time when height variation is sensed. By performing along scan at a coarser resolution and short scans a high resolution using the same probe tip or two probe tips at fixed relative positions, data obtained from the long and short scans can be correlated accurately.

Abstract: A novel method and a suitable device for the cylinder-specific determination of spark failures on a reciprocating engine through a classifying unit based on measurement data that contain information about the number of crankshaft revolutions. For this process, the measurement data are subjected to a pre-processing procedure in the classifying unit and classified through a classification process, wherein within the framework of the pre-processing procedure the data are subjected to a principal axis transformation (HAT). Due to the utilization of this resource-saving method for detecting spark failures on reciprocating engines in accordance with the invention, the processing requirements for once cycle are less than 5 Kflops, despite a measurement vector v length of 240. Due to the fact that the invented device requires only a single measurement data recorder, e.g.

Abstract: A brake operating device in which a stable input/output characteristic of a brake pedal operation amount and a brake booster device transmitted amount can be obtained, and the input/output characteristic can easily be set to a desired form. In the brake operating device, a connecting pin of a push rod is fit in and connected with a connecting hole of a brake pedal. The connecting pin is fit in a guide hole of a guide plate.

In this case, because frictional force is reduced, a predetermined, stable pedal ratio can be obtained. A pedal ratio corresponding to a desired characteristic can easily be obtained, and degrees of freedom in design increase.

Abstract: A front lid opening and closing assist which enables an easy and safe operation of opening and closing a front lid of a keyboard instrument. A buffer in the front lid opening and closing assist has a first damping mechanism for damping the front lid when pivoted from a neutral position to an open position, and a second damping mechanism for damping the front lid when pivoted from the neutral position to a closed position. When the front lid is pivoted beyond the neutral position, it spontaneously pivots toward the open or closed position by its own weight. However, this motion is damped by the first and second damping mechanisms, which results in a slowed pivot motion of the front lid. As a result, a user can safely open or close the front lid relative to a back lid, with only minimal force for supporting the front lid.
