Title: Mold for vulcanizing tire and pneumatic tire
Inventor: MORIYA MASASHIROU
IPC: B60C11/12
Filed: 1996-08-12
Abstract: PROBLEM TO BE SOLVED: To effectively suppress an irregular wear of a land portion formed with a flask type sipe of a tire.

IPC: B22D11/126
Filed: 1982-12-03
Abstract: PURPOSE:To optimize the cutting speed for a billet and to facilitate cutting by forming a timbre pattern from the cutting sound of a cutting torch moving integrally with the billet, comparing the same with a set timbre pattern and controlling the movement of the torch. CONSTITUTION:A moving carriage 4 is moved in a direction A at the same speed as the speed of a billet 2 and a torch 5 is ignited and the cutting of the billet 2 is started by moving a torch moving device 6.
