Title: Road floor ballast recovery device
Inventor: ISHIDA MICHIO
IPC: E01B27/04
Filed: 1995-01-07
Abstract: PURPOSE: To enhance work efficiency by rotating a scraping-up rotor so that ballast can be scraped up by a hydraulic motor, by detecting the pressure of pressure oil being supplied to the hydraulic motor, and when a pressure rise due to overload is caused, by once reversing the hydraulic motor. CONSTITUTION: When ballast W is scraped up by a scraping-up rotor 13 of a scraping-up part 11, if the rotation of the rotor 13 is brought into an excessive load condition due to the scraping-up clogging of the ballast W or the like, a pressure detecting means 25 detects the rise in the pressure oil being supplied to a scraping-up hydraulic motor 14, and once the rotation of the hydraulic motor 14 is reversed by means of a hydraulic control means 27, and the rotor 13 is reversed to push out the ballast W for eliminating the clogging condition, and again it is normally turned to carry out the scraping-up rotation. Thus, the scraping-up operation by the rotor 13 can be smoothed, and even if the ballast W may be various sizes of crushed stone, gravel, or the like, it can be properly scraped up and can be efficiently recovered.  By using a pressure switch 26 as the pressure detecting means 25, the pressure rise can be easily detected, and also by providing a means for controlling the reversing time of the hydraulic motor 14, after reversing for a prescribed time, the motor can be securely turned in the normal rotation.

Title: Network managing method/device
Inventor: MATSUO AKIHIKO
IPC: H04L12/437
Filed: 1999-01-26
Abstract: PROBLEM TO BE SOLVED: To provide a network managing device where a processing is easy and burden on hardware is less by executing a link establishment recognition processing judging that a network becomes a state where it normally functions and an error monitoring processing judging the occurrence of a fault. SOLUTION: When a restoration post-processing part 11 judges a link state with an upstream node and recognizes establishment, a node moves the state to a link establishment recognition processing part 12. The link establishment recognition processing part 12 once gives an establishment notice immediately after movement and monitors and repeats status information of one bit, which is sent. When all links are established and the nodes become an operation possible state, the nodes give status information for prescribed time or for the prescribed number of times, which are previously decided. A processing is moved to an error monitoring/notifying processing part 13.  When the node monitors status information and detects the occurrence of a fault in the link existing between the upstream nodes, it gives status information notifying the occurrence of the fault to the node positioned downstream.

Title: Brake for bicycle
Inventor: NAGANO MASASHI
IPC: F16D51/16
Filed: 1983-02-04
Abstract: PURPOSE:To prevent partial abrasion of a braking surface by supporting the forward side of a leading shoe on a support member, the movement of which is regulated along the turning direction of a drum through an anchor to obtain the braking force more than a leading effect. CONSTITUTION:A shoe 2 is brought into pressure contact with a drum 1 to apply braking force to the drum 1, and the turning torque of the drum 1 works upon the leading shoe 2, so that self-braking force works upon the leading shoe 2. The leading shoe 2 is moved in the same direction as the turning direction of the drum 1 by the self-braking force, and the movement causes an anchor to operate counterclockwise on a supporting position for supporting the anchor on a support member 10, so that the shoe 2 is forcibly brought into pressure contact with the inner peripheral surface of the drum 1 strongly. Thus, a very great braking force can be obtained by large contact pressure of the anchor 5 and self-braking force, though an input is small.
