A milling tool includes a rotary cutting head having an end surface in which grooves are formed. The grooves communicate with a duct extending coaxially completely through the center of the cutting head to conduct cooling / lubricating fluid to cutting inserts mounted at outer ends of the grooves. The grooves induce a flow of fluid from inner ends of the grooves to the outer ends in response to rotation of the cutting head. A removable deflector can be attached to the end surface to deflect fluid from the main duct to the grooves.

This invention relates generally to a collapsible, nesting wing structure with or without wing warp flight control. The invention also incorporates means to maintain wing extension during flight, methods of wing construction for nesting collapsible wings, and control surfaces for collapsible wings.

A multi-walled, tubular baseball bat has a barrel portion with a mid-section wherein the radial stiffness of the overall barrel wall varies along the barrel length to provide an enlarged sweetspot, improved soft feel and performance, plus unique sounds upon impact. The bat has a frame with a barrel portion of consistent diameter. A secondary member, or members, of tubular form extend internally along the barrel. The secondary member provides the required radial stiffness variation by: 1) variations in the thickness of the wall of the secondary member or by, 2) secondary members with unique geometric external surface profiles or by, 3) the presence of functional air cavities, with or without closed ends, between the main bat frame and the secondary member or members or by, 4) the presence of numerous annular secondary members located side by side less than one-half the length of the barrel portion.

A seat mounting rail for securing seats to a floor of a passenger aircraft is made of a seat securing upper section and a rail mounting lower section. Both sections are made of different metals. The upper section is made of a titanium alloy for corrosion protection. The lower rail section is made of an aluminum alloy for weight reduction. The interconnection between the two sections is made as a thermal joint for example formed as a laser weld, which is preferably a butt weld to save welding material.

A power transmitting device for a vehicle for transmitting a driving force from a driving source to right and left axles. The power transmitting device includes a housing, a planetary gear type speed reducing mechanism connected to the driving source, a differential gear unit arranged in coaxial relationship with the planetary gear type speed reducing mechanism and connected to the right and left axles, and an oil reservoir provided in a lower region of the housing. The differential gear unit has a differential case formed integrally with a planetary carrier of the speed reducing mechanism. The planetary carrier includes first and second annular members axially spaced apart from each other and a plurality of connecting portions for connecting the first and second annular members, each of the connecting portions having a substantially V-shaped configuration opening outward in the radial direction of the first and second annular members.

An electric vehicle and a range extender engine are shown including the controls to operate the same.

To provide a vehicle which can move independently as an own independent vehicle and can run integrally in linkage with another vehicle. A plurality of single-seat vehicles which can move independently are combined and they move integrally while a predetermined formation is maintained through linkage among respective vehicles. One of all the vehicles moving in linkage serves as a host vehicle and an occupant in the host vehicle becomes a driver in the linkage moving. A host vehicle 1 runs with speed / direction according to running operation conducted by an occupant. Simultaneously therewith, the host vehicle 1 instructs following vehicles 2 to 4 to synchronize (follow) the host vehicle. The host vehicle 1 transmits a speed, a direction, and a relative position to the host vehicle to the following vehicles 2 to 4 as moving information in order to synchronize the following vehicles with the host vehicle (maintain linkage relationship). The following vehicles 2 to 4 move based upon a follow-up instruction and feed status information including speeds and directions of the following vehicles, and their own positions back to the host vehicle 1 as own vehicle information.
