Abstract:
A center take-off rack-and-pinion steering apparatus includes a cylindrical rack housing having an elongate hole extending in a longitudinal direction, a mounting bracket for mounting ends of a pair of tie rods on a rack shaft, and a slider interposed between the mounting bracket and the rack shaft and slidable in an inner periphery of the elongate hole. The inner periphery of the elongate hole and the slider include sliding contact sections that are brought into sliding contact with each other along with the slide of the slider slides. The sliding contact sections include at least a pair of curved sliding contact surfaces that are brought into sliding contact with each other in a curved shape when seen in an axial direction of the rack shaft.
Abstract:
A steering apparatus includes an attaching bracket connecting end portions of a pair of tie rods to a rack shaft. The attaching bracket includes a base which is fixed to the rack shaft and includes at least one fixing member inserting hole through which a fixing member fixing the attaching bracket to the rack shaft is provided, and a supporting stay supporting the end portions of the pair of tie rods via ball joints respectively. The supporting stay extends from an intermediate portion of the base in an axial direction of the rack shaft. A center of the ball joint supporting the end portion of each of the tie rods is positioned offset from an axial line of the fixing member by a predetermined distance when viewed along the axial direction of the rack shaft.
Abstract:
With a tag holding member and a device including the tag holding member, a commodity product can be detected by a detector even if the product is taken out of a packaging case. A holding member with a tag member includes a holding part having a groove for engaging with an upper end part of a chassis and a projection for engaging in an opening of the chassis, whereby the engaging part is engaged with and held by the upper side face and the opening of the chassis with high precision. The tag member is provided at a higher position than the upper end part of the chassis, and a distance from the outer cover can be set optionally. The holding member is held at the side face part of the chassis and covered with the outer cover, therefore the member can be held inside the commodity product.
Abstract:
In a development portion (2) of a directed graph, when a program specification (1) is provided, descriptive elements having characteristics of sets described in the specification and descriptive elements defining a calculation method described therein are mapped with vertices and arcs based on descriptive elements defining a calculation method described therein are drawn between the vertices. Thus, the program specification is developed to the directed graph. The developed directed graph is analyzed by an analyzing portion (3) in view of the characteristics of sets and mappings and global characteristics of the directed graph, and arcs and vertices where flows of execution timing of the calculation synchronize and arcs and vertices where flows of execution timing of the calculation do not synchronize are detected. A program structure defining portion (4) handles the arcs and vertices where the flows of timing synchronize and the arcs and vertices where the flows do not synchronize, by different methods, thereby determining a data structure and a procedure structure as the program structure.
Abstract:
A rack and pinion steering device has a pinion rotatable in the R-direction, a rack bar having rack teeth meshing with the pinion and rectilinearly movable in the A-direction, a housing for rotatably supporting the pinion, a rack guide for slidably supporting the rack bar, and an elastic means for pressing the rack guide toward the pinion.
Abstract:
A drainpipe cleaning apparatus prevents leakage of cleaning fluid from the drainpipe while cleaning the drainpipe. The drainpipe cleaning apparatus 1 has a cleaning fluid tank 10 for storing the cleaning fluid, a fluid delivery line 15, fluid drain line 23, gas-liquid separation tank 24, gas exhaust line 26, circulation line 28, gas recovery line 31, cleaning fluid return line 33, and control device 45. The control device 45 runs a cleaning process by driving a gas discharge pump 36 to create negative pressure inside the wastewater drainpipe 2 in a transit vessel and driving a cleaning fluid pump 16 to cause the cleaning fluid to flow backwards through the wastewater pipe 2. The control device 45 also monitors the pressure detected by a inlet-side pressure detector 20 during the cleaning process. If the detected pressure exceeds atmospheric pressure, the control device 45 runs a cleaning fluid recovery process that stops the cleaning fluid pump 16, closes the discharge valve 19, opens the cleaning fluid return valve 34, opens the release valve 27, and closes the gas recovery valve 32 so that cleaning fluid in the wastewater pipe 2 flows back through the fluid delivery line 15 and cleaning fluid return line 33 and is recovered in the cleaning fluid tank 10.
Abstract:
A method of manufacturing a rack guide base body wherein a cavity (40) is formed which has a pair of semicylindrical convex surfaces (44a and 44b) and a pair of flat surfaces (45) each located between the semicylindrical convex surfaces (44a and 44b), and has a recessed surface (41) located on one axial end portion side inwardly of the semicylindrical convex surfaces (44a and 44b) and the flat surfaces (45) and a cylindrical surface (42) located on the other axial end portion side inwardly of the semicylindrical convex surfaces (44a and 44b) and the flat surfaces (45); a hollow portion (9c) is formed for allowing the cavity (40) to communicate with a hollow portion (10c) at one flat surface (45) and with a hollow portion (8c) at the other flat surface (45); a rack guide base body (50) is die cast by forcing molten metal of aluminum from the hollow portion (10c) into the cavity (40); and runners (56) integrally joined to flat surfaces (55) of the rack guide base body (50) formed by the respective flat surfaces (45) are cut off.
Abstract:
Prior to engaging a male screw formed on the outer circumference of a second member with a female screw formed on the inner circumference of a hole in a first member, protruding parts which protrude outward in the radial direction and are positioned at one end side of the male screw in the axial direction are formed in a plurality of regions which are separated from each other in the circumferential direction on the outer circumference of the second member on which the male screw is formed. The male screw is then engaged with the female screw from the other end side of the male screw in the axial direction. The torque required to rotate the male screw engaged with the female screw in the loosening direction is set so as to be greater in a state where the protruding parts are interposed between the male screw and the female screw than in a state where the protruding parts are not so interposed.
