摘要： The straightness and parallelism of a track surface on which rollers roll are measured within a range “L2” as a range for measuring the straightness and parallelism. The range “L2” is a range such that L2≧0.8×L when a roller length is “L”. When the dimension from the corner P of the flange on the inner diameter side to the starting point of the range “L2” is “L1”, the dimension “L1” is ranged such that 0.8 mm≦L1≦2 mm. In this range, the straightness of the track surface of the outer ring in the axial direction is not more than 0.008 mm and the parallelism thereof is not more than 0.015 mm.

摘要： A rotary unit with a built-in clutch which is short in its axial length. The rotary unit has an inner member having an outer periphery formed with a raceway groove and a pair of cylindrical surfaces on both sides of the raceway groove, and a cylindrical outer member having an inner periphery formed with a raceway groove and a pair of cylindrical surfaces on both sides of the groove. A retainer mounted between the inner and outer members has a plurality of circumferentially spaced pockets each housing a rolling member and sprag housing recesses provided alternately with the pockets. In each recess is received a sprag having both ends thereof resting on the opposing cylindrical surfaces and biased by a resilient member so that its inner and outer arcuate surfaces contact the cylindrical surfaces. By arranging the sprags and the rolling members alternately with each other in the circumferential direction, it is possible to reduce the entire axial length of the rotary unit.

摘要： In an image processing method, extraction points are set inside the draw line as the region with less luminance change relative to the periphery, and extraction points are set on the background outside the draw line in a sample image such as a letter and a number. Pixel data of the extraction points are used to obtain the normalization correlation coefficient with respect to the target image in the determination region. As the template data are generated using pixel data of two groups of the extraction points with clear contrast in the luminance difference therebetween, the true image to be determined as being the same as the template image is detected accurately through the calculation for a short period of time.
摘要翻译：在图像处理方法中，将提取点设置在绘制线内部，作为相对于周边的亮度变化较小的区域，并且将提取点设置在诸如字母和数字的样本图像中的绘制线外部的背景上。使用提取点的像素数据来获得相对于确定区域中的目标图像的归一化相关系数。由于使用两组提取点的像素数据生成模板数据，所以在其间的亮度差异方面具有清晰的对比度，因此通过计算短时间段来准确地检测与模板图像相同的真实图像时间。

摘要： A torque limiter having an outer ring with a plurality of cam surfaces and spring supporting surfaces formed on an inner peripheral surface, an inner member mounted in the outer ring, and a plurality of rollers mounted between the cam surfaces and the inner member. Springs supported on the spring supporting surfaces bias the rollers in a direction to bite into the cam surfaces and the inner member. The springs have a predetermined spring force which is sufficient to maintain the rollers in wedging engagement between the cam surfaces and the inner member when a turning torque for turning the inner member in a direction to urge the rollers out of the wedging engagement is applied to the inner member, but only until the applied torque reaches a predetermined value.

摘要： An ink jet head used for pulsed droplet ink jet printer uses a grooved piezo-electric element. The piezo-electric element includes a plurality of grooves, diaphrams and actuators. The actuator and two grooves at both sides of the actuator, filled with stuffing material, covers a corresponding one of passages. Therefore, even if the stuffing material moves when the actuator is energized, an interference problem does not occur. Consequently, the flexure force of each actuator can transmit to the corresponding passage to jet ink in the passage via a nozzle.
