Abstract: In a rack and pinion type motor-driven power steering apparatus, the motor-driven power steering apparatus is provided with a rack position detecting means for detecting a position of the rack, a rack speed arithmetically operating means for calculating a moving speed (s) of the rack, a memory means for storing a relation between a predetermined rack speed (s) near a stroke end of the rack and a motor damping control start rack position in which a distance from the stroke end is farther in accordance with the rack speed (s) as a relation curve (C) of a coordinate map A collating means is provided for collating with the relation curve (C) between the rack speed (s) stored in the memory means and the motor damping control start rack position so as to determine whether or not a point coordinate (s, p) of the combination between the rack speed (s) calculated by the rack speed arithmetically operating means and the rack position (p) detected by the rack position detecting means gets over the relation curve (C).
Abstract: The invention relates to a blind rivet, a rivet pin, a holding device, a method for producing a blind rivet and a method for creating a riveted joint which enables a permanent joint to be produced between several workpieces in one working cycle.
Abstract: In a power tilt apparatus in which an operation state of a cylinder apparatus is switched between an extension side and a compression side in accordance with an oil feeding direction of a pump apparatus by a switching valve apparatus provided in a pipe passage connecting the cylinder apparatus and the pump apparatus, where a sintered body filter is provided in the middle of the pipe passage.
Abstract: One end of a passenger bridge or a goods-handling device of mobile type can be expediently and securely connected to a door on a craft, especially an aircraft, by determining the position of the door in relation to a reference point on the craft and storing it in a computer system. Furthermore, the absolute position of the door when the craft has come to a halt and the passenger bridge or the goods-handling device is to be connected, is determined by measuring the distance from a reference point on the ground to the craft. Finally, the computer system guides the passenger bridge to the door of the craft, the position of the end of the passenger bridge or the goods-handling device being determined during the guiding operation and inputted into the computer system.
Abstract: A sorting apparatus 10 which uses a sorting/conveying line 11 with branch destination, including a branch line 22 for sorting the commodities more than a quantity necessary for the branch destination and a surplus article returning line 23 for returning surplus commodities after removing a required quantity to the sorting/conveying line 11.
Abstract: In a direct current motor drive bridge circuit structured such that a pair of forward rotation switching elements and a pair of reverse rotation switching elements are alternately connected annularly, a direct-current motor is interposed between diagonal node points on one side, and a power source voltage is applied to a portion between diagonal node points on another side via an existing resistance. A fault detection apparatus of the direct-current motor drive bridge circuit is provided with a fault detection circuit for detecting an electric potential of the one node point r to which the power source voltage is applied via the existing resistance and for detecting a closed-circuit fault of the switching elements and on the basis of a fluctuation of the electric potential.
Abstract: A middle portion 62 of a fitting portion 52A of a boot 52 for a universal joint is fastened to a flange-like portion 72 of a member to which the boot is attached and a front end portion 63 to which communicating paths 61A to 63A of the boot 52 are opened is faced to a small diameter periphery portion 73 following one side of the flange-like portion 72 of the member to which the boot is attached.
Abstract: A device and procedure for portioning a piece of food in portions with a predetermined weight or predetermined thickness. The device has a pivotable insertion drum (1) arranged in a rotatable manner around its axis with at least one oblong insertion chamber (4) for inserting the piece of food. A knife (3) is arranged on the insertion drum (1) for cutting a portion located in the portioning chamber from the rest of the piece of food.

Abstract: In a bottom valve apparatus of a hydraulic shock absorber in which a flow passage is formed in a bottom piece, and a check valve opening and closing the flow passage and a spring urging the check valve are fixed to one face side of the bottom piece by a fixing member, such as a nut, the check valve and the spring are subassembled in the fixing member, such as the nut.
Abstract: This invention provides a dynamic damper comprising an outer pipe 20, a weight 30 and an elastic body 40, wherein convex portions 21 protruded in the direction of the inside diameter are provided at plural positions along the circumferential direction of the outer pipe so as to hold the elastic body 40 by sandwiching the outer circumferential portion of the elastic body 40 between adjacent the convex portions.
Abstract: The present invention relates to an arrangement for a Ro—Ro vessel, which exhibits a number of cargo-receiving spaces provided with a driving surface internally in the vessel, and with a ramp extending between one such space and a quay, along which ramp driverless cargo handling vehicles (7), known as AGV vehicles, are capable of being driven between designated parking places for the purpose of transporting cargo between the quay and the aforementioned cargo-receiving space of the vessel. Means (9) are provided for causing the cargo handling vehicles (7) to be guided between the aforementioned spaces and the quay and into the intended train of vehicles in the designated location in a line (II) and without connecting the cargo handling vehicles (7) to one another.
