摘要:
A cage for a roller bearing which is free of fretting and abnormal noise, which can be manufactured at low cost, and which can be easily mounted in the bearing. The cage is formed by bending a metal sheet having pockets into a ring shape, temporarily joining its ends, heat-treating the ring thus formed to remove stress, and separating the temporarily joined portion. Such a cage tends to rotate slower than the raceway members on the driving side of the bearing, making it possible to reduce fretting. Such a cage can be used under high-temperature conditions.

In reading an original by mounting reading means (scanner unit) on a recording apparatus, the advancing width of the original is so reduced that the reading bands k, k+l, . . . , are partially overlapped. For example in the color image reading, in generating the data of the (k+1)-th band, the data of a range overlapped with the k-th band are corrected by the data of the k-th band (for example by simple averaging), thereby achieving image reading without bandwise density fluctuation regardless of the reading mode and the original size.

An apparatus for improving the reliability of a course generator of a moving body and the efficiency of the moving body. When the tangent (53) of a scheduled course (50) at its branch point (PS) is in parallel with a line segment (54) coincident with the traveling direction of the moving body (20) at the end point (PL) of a branch course (52), the branch course (52) is generated from a cubic curve having one extreme coincident with the branch point (PS), and the tangent of the cubic curve at this extreme coincides with the tangent (53) of the scheduled course (50) at the branch point (PS). The other extreme of the cubic curve coincides with the end point (PL) of the branch course (52), and the tangent of the curve at this extreme coincides with a line segment (54) which in turn coincides with an end point traveling direction of the moving body. A ground monitor station (40) guides and travels the moving body (20) along a modification of the branch course. When guided for traveling, the moving body (20) generates the modification of the branch traveling course. When any of the moving bodies generates the data of the modified course and transmits it to the ground monitor station (40) in this way, the ground monitor station (40) again generates the scheduled course and the branch course on the basis of the data of the modified course, and transmits the re-generated data of the course to each moving body.

In accordance with the equipment of the present invention, the communication over the entire region of a wide working site can be performed without a cost increase due to the installation of auxiliary equipment, the mutual control of vehicles can be performed with a light burden on a monitoring station without sacrificing safety, and when a failure occurs to transmission/reception equipment, the failure can be quickly and accurately confirmed, and accordingly the abnormality can be quickly and properly dealt with. In the of the present invention, first transmission/reception system for transmitting/receiving at least command data between the monitoring station and a plurality of vehicles via a first communication system which enables wireless communication over the distances between the monitoring station and the vehicles is provided in the monitoring station and the vehicles respectively. Second transmission/reception system for transmitting/receiving position data measured by vehicle position measurement between the vehicles via a second communication system which enables wireless communication over the distances between the vehicles and enables faster data transmission/reception than the first communication system is provided in the vehicles respectively. The respective vehicles judge the approach of another vehicle by transmitting position data between the vehicles via the second transmission/reception system provided in the vehicles respectively, so that the mutual position relationships between the vehicles can be monitored.
摘要:
A teaching method includes dividing an automatic traveling course (96) into a plurality of zones before teaching, conducting teaching for each zone of a plurality of zones at the time of teaching so as to generate position coordinate data for each zone as course data for each zone, and combining course data for respective zones and store the same after teaching. An apparatus includes a teaching zone designating function section (41) for designating a zone inside an automatic traveling course (96) divided into a plurality of zones, a position coordinate data function section (42) of an unmanned vehicle (3), zone-specific traveling course data memory means (43), a teaching course data writing function section (44) for writing the position coordinate, a teaching data edit instruction function section (45) for outputting an instruction after the completion of teaching route, and a total traveling course data edit function section (46) for combining and editing the traveling course data. Thereby the change of teaching of the course can be made within a short time.
摘要:
A method for automatically changing the speed of a dump truck for use as a construction vehicle which is capable of improving the fuel cost by utilizing the engine output effectively and efficiently, improving the durability of the power transmission system and giving the driver a comfortable ride. According to this automatic speed change method, a desired, optimum speed stage which meets the loading condition of the dump truck and/or the engine output condition can be selected by using controllers each having a built-in computer.

Disclosed is an information reading/printing apparatus in which a carriage supports and moves a printing unit for printing information on a printing medium and a reading unit for reading information. The position of the carriage moved in each of left-to-right and right-to-left directions is detected.
摘要:
Disclosed is an image reading apparatus in which the band width for reading by one scanning is variable in accordance with the original size, the reading mode, etc. R, G, and B image data of the k-th band is successively read in one-band width to store image data R1, G1, and B1 of pixel coordinates X(n, m). Then, the original is fed so as to cause partial overlapping of the (k+1)-th band with a lower predetermined pixel region of the k-th band, and R, G, and B image data of the (k+1)-th band is read in one-band width to successively store image data R2, G2, and B2 of pixel coordinates X(n, m′). The image data obtained through overlap reading of the k-th band and the (k+1)-th band is averaged to calculate correction image data, which is transferred to a host computer along with along other image data which has not been averaged as read image data. And, it is possible to optimize reading time according to the kind of original, reading mode, etc., without involving a deterioration in image quality.
