A brake device includes a controller for inputting detection signals from an engine speed sensor, vehicle speed sensor, shift lever position sensor and engine exhaust brake sensor. When a vehicle speed upon application of engine exhaust brake is lower than a low speed set value of an effective vehicle speed corresponding to a shift lever position, a lockup clutch of a torque converter is disengaged by the controller; and when the vehicle speed is in a range from the low speed set value to a high speed set value of the effective vehicle speed, the lockup clutch is engaged by the controller; and when the vehicle speed exceeds the high speed set value, the lockup clutch is disengaged, and a transmission is down-shifted to a just lower gear range by the controller.

Heat-treated steel of particular, but known, composition is quenched, worked in one direction and then hardened by tempering to form a uni-directional lamellar structure of tough martensite in a uniform austenite matrix.

Steel having a uni-directional lamellar martensite structure in an

Disclosed is a continuous atmosphere controlled furnace for aluminum brazing and other purposes. A plurality of pots are suspended from a circular roof rotatable in a horizontal plane and arranged in a circle having a center on the axis of rotation of the roof. Each pot comprises a body having an open top and a cover capable of closing the open top of the body. The open top of each pot projects above the roof and that portion of each pot which contains the material to be heated extends downwardly below the roof. The material to be heated is supported on a hanger depending from the cover of each pot and the cover is lowered to place the material in the pot and close the pot. The furnace further includes an atmosphere gas distributor having its center on the axis of rotation of the roof and connected to the pots by gas supply and exhaust ducts. A method of supplying atmosphere gas through the pots is also described.
