Title: Pneumatic tire for heavy load
Inventor: KAJIMOTO KATSUHIKO
IPC: B60C11/11
Filed: 1982-10-04
Abstract: PURPOSE:To improve wear resistance of a block pattern, by a method wherein the entire surface area of a second block file is made larger than that of a shoulder block file and both blocks are arranged in a crossing state so that center lines of lateral grooves of both blocks do not coincide with each other. CONSTITUTION:A tread area of a land part of a second block file 4 is made larger than that of a shoulder block file 3 by making an opening area in a tread of a lateral groove 5 of the shoulder block file 3 larger than that of the second block file 4. Both the blocks are arranged in an uneven state so that the lateral grooves 5 and 6 of both the blocks 3 and 4 do not become in a line with each other. With this construction, effective expansion of an effective tread area and alleviation of concentration of the tread in a block edge of an edge part of the lateral grooves 5 and 6 are contrived as a whole and an improvement in wear resistance is realized.

Title: Duct connecting structure in chip removal device
Inventor: OKETANI TETSUYA
IPC: B23B47/34
Filed: 1998-06-22
Abstract: PROBLEM TO BE SOLVED: To extend the life of a duct through which chips in a pressure foot are sucked and removed. SOLUTION: Chips generated near a tool T by boring using the tool T are sucked up by suction airflow and then sucked directly upward from within a spindle compartment 21 via a communicating hole 25 and from the suction part 32b of a suction pipe 32 that opens downward in a suction chamber 22, so that the chips are conveyed to a dust collector 50 through suction piping 33. Since the chips sucked into the suction pipe 32 move along a spindle axis after suction and do not greatly vary in moving direction, they do not strongly rub against the interior walls of the suction pipe 32 and the suction piping 33, and the retnation of boring of holes in the wall surfaces of the suction pipe 32 and the suction piping 33 in a short time is avoided.
