A helical blade cutter including multiple linear blades attached to an outer circumferential surface of a round body having an outer surface formed into a cylindrical circumferential surface. The blades tilt to a given helix angle &#x3b1; from a straight line on the outer circumferential surface parallel to a rotational central axis O. Blade attachment surfaces are formed on the outer circumferential surface of the round body at given intervals in the circumferential direction. The blade attachment surfaces tilt to an angle same as the helix angle &#x3b1; of the blade while tilting to a rake angle &#x3b2; in a direction of an elevation angle from a tangent to the outer circumferential surface. The blades are each attached to a blade attachment part through intervention of a chip holder that allows detachment of the blade.

A remote control for controlling a controllable device, including: an infrared transmitter that transmits information via infrared light; a wireless transceiver that transmits information by wireless communication via radio waves; a receiver that receives, from a user, control information to be transmitted to the controllable device; a wireless communication determination unit configured to determine whether wireless communication between the wireless transceiver and the controllable device is possible; and a control unit configured to select, based on a result of the determination by the wireless communication determination unit, one of the infrared transmitter and the wireless transceiver for transmission of the control information to the controllable device, and cause the selected one of the infrared transmitter and the wireless transceiver to transmit the control information to the controllable device.

Remote control and communication method for remote control

With a rack-and-pinion mechanism, an impact force is absorbed and reduction in assembling performance is suppressed. An annular fitting groove () that extends in the circumferential direction of a rack guide () is formed in an outer peripheral face () of the rack guide (), and an O-ring () is fitted in the fitting groove () in a state in which the axial movement of the O-ring () is restricted. A communication groove () that provides communication between an internal space (), defined by the fitting groove () and the O-ring (), and the outside of the rack guide () is formed in the rack guide ().

A bearing mechanismincludes a housinghaving a cylindrical inner peripheral surface, a rack shaftinserted and secured in the housingand having a cylindrical outer peripheral surface, and a sliding bearinginterposed between the inner peripheral surfaceof the housingand the outer peripheral surfaceof the rack shaft

Bearing mechanism having sliding bearing

A bush bearing includes a synthetic resin-made bush having a circumferential groove on its outer peripheral surface; an endless annular elastic member fitted in the circumferential groove of the bush; and a positioning structure for determining the position of the bush in a B direction with respect to an inner peripheral surface of a gear housing.

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.

Center take-off rack-and-pinion steering apparatus

A method of manufacturing a rack guide base body wherein a cavity () is formed which has a pair of semicylindrical convex surfaces (and) and a pair of flat surfaces () each located between the semicylindrical convex surfaces (and), and has a recessed surface () located on one axial end portion side inwardly of the semicylindrical convex surfaces (and) and the flat surfaces () and a cylindrical surface () located on the other axial end portion side inwardly of the semicylindrical convex surfaces (and) and the flat surfaces (); a hollow portion () is formed for allowing the cavity () to communicate with a hollow portion () at one flat surface () and with a hollow portion () at the other flat surface (); a rack guide base body () is die cast by forcing molten metal of aluminum from the hollow portion () into the cavity (); and runners () integrally joined to flat surfaces () of the rack guide base body () formed by the respective flat surfaces () are cut off.

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.
