Title: End cap type ball screw
Inventor: SATO HIDEYUKI
IPC: F16H25/22
Filed: 1992-11-30
Abstract: PURPOSE:To restrain vibration in an elastic deformation mode, and thereby suppress noise down by covering a ball circulation member made out of soft material such as synthetic resin and the like which can be formed into a complicated shape, by each metallic reinforcing member and the like from the outside, which are high in stiffness and density. CONSTITUTION:Each end cap 15 is formed by pressing a cylindrical ball circulation member 5 into each reinforcing cap 16 with pressure where the ball circulation member is made of synthetic resin while being formed by injection molding, and each reinforcing cap is made of metal such as stainless steel for covering a cylindrical surface 5a and a circular surface 5b. Each ball 3 is rolled within spiral grooves 1a and 2a as a ball screw nut 2 is advanced, each ball comes to the end cap at one end so as to be led into the curved path 7 of the ball circulation member 5, so that each ball comes in a ball return passage 6 within a nut main body 4. When each ball comes to the end cap 15 at the opposite side, each ball is turned over while being led by the curved path 7, so that each ball is returned to the spiral grooves 1a and 2a. Since the outside of the ball circulation member 5 is covered by each reinforcing cap 16, the-overall strength of each end cap 15 is thereby increased.

IPC: G01N21/31
Filed: 1999-11-12
Abstract: PROBLEM TO BE SOLVED: To prevent the blowoff of a flame or a backfire from being generated due to the instability of a burning operation when the kind of a supporting gas is changed over. SOLUTION: Before a combustion gas is changed over to N2O from air, a gas control part 11 controls a flow rate valve 19. A gas flow rate which is optimum for the analysis of an air-ethylene flame is increased once to a fuel gas flow rate up to a value required for a stable burning operation. A valve 20 is opened, and the gas flow rate is increased up to a value required for the stable burning operation of an N2O-acethylene flame. Immediately after that, the supporting gas is changed over by a three-way selector valve 21. A burner 14 is moved by a motor 13 after the flame is stablized. After the movement of the burner is finished, the gas flow rate is reduced down to a value optimum for the analysis of the N2O-acethylene flame.  As a result, when the supporting gas is changed over or the burner 14 is moved, the flame is in a stable burning state, and it is possible to prevent the blowoff of the flame or a backfire.
