Patent EP-0118840-A2 (EP)
Inventor: TERHUNE JAMES HOWARD
IPC: G01N29/024
Filed: 1984-03-01
Abstract: Sound waves are generated in a sonic cell and propagated through a gas to a sensor which is coupled to a microcomputer. A gas mixture is first directed into a chamber and the attenuation and transit time of sound waves are calculated. Then, a calibrated gas is directed into the chamber, and the attenuation and transit time are again calculated. With these measurements, the microcomputer calculates the concentrations of at last two gaseous constituents such as hydrogen and water vapor, in the gas mixture. The microcomputer acts also as a control for operating valves and heater coils in response to pressure and temperature sensors coupled with the chamber.

Abstract: A method of producing fine particles with a particle size of submicron or finer which comprises the steps of:
     forming closely fine projections on a substrate surface, preferably by sputter-etching using an ionized gas; and then   sputtering metallic or non-metallic materials onto the thus treated substrate in an inert gas or a mixed gas of an inert gas and a reactive gas, such as oxygen, the gas pressure of the inert gas or the mixed gas being in the range of from 1×10 -4  torr to 1×10 -1  torr, and thereby depositing the purposed fine particles in crystalline or amorphous form. The invention method can successfully provide fine particles with desired properties, for example, in size, shape and structure, by adjusting producing conditions or selection of substrate materials and the thus obtained fine particles are very useful in various applications with or without the substrate.

Abstract: There is disclosed a process and apparatus for induction hardening of the flank, root and tip surfaces of the teeth (A to E) of a gear (1) so as to provide a surface-hard layer (33) along said surfaces. An electrically energisable inductor head (11 a) carries out traversing movement along the space between a pair of adjacent gear teeth (B, C), the inductor head having an external profile substantially matching the profile of the space between the gear teeth. Guides (31, 32) maintain predetermined clearances between the inductor head (11a) and the tooth surfaces (B2,36, C1) which define the tooth space, during traversing movement of the inductor head, the clearance being a minimum between the inductor head and the root surface (36) and varying in predetermined manner along the flank surfaces (B2, C1) in such a way as to achieve heating along the flanks and root surfaces to a substantially uniform predetermined temperature suitable for induction hardening. Jets of coolant (34, 35, 46, 47) are directed to the surfaces of the unheated flanks (B1. C2) the tips (B3, C3), the heated flanks (B2, C1) andthe root (36) of the pair of gear teeth (B, C) so asto achieve relatively rapid cooling of said surfaces. 
     The entire gear (1) is immersed in a tank (2) of coolant (3), which is a mineral oil or other non-aqueous quenching agent. The height of the inductor head (11a) is less than the depth of the space between the root (36) and tip (B3, C3) surfaces of each pair of gear teeth. 
     The operating parameters of a) the predetermined clearances, b) the rate of electrical energy supplied to, and the speed of traversing movement of the inductor head and c) the rate of cooling, are controlled in such a way as to form a substantially uniform thickness surface-hardened layer (33) from tip to tip along the flanks and root surfaces of the pair of gear teeth, the surface-hardened layer having an internal structure which is such as to impartthe equivalent of built-in compressive stress in its surface (33a), at least in the region of the root curve (36) and its transition to the flank surfaces (B2, C1). This built in compressive stress enables each tooth to withstand more reliablythe tensile stresses which are applied to gear teeth, when intermeshing gear teeth apply fatigue bending loads to each other.
