Title: Taper-grinding system
Inventor: YOKOGAWA KAZUHIKO
IPC: G05B19/18
Filed: 1978-03-30
Abstract: PURPOSE: For grinding the tapering portion of work without fail by means of a grinding wheel, to decrease the circumference offsetting value of said grinding wheel step by step while feeding said grinding wheel in Z-axial direction by a fixed pick- feed value at each time of the execution of 2-dimensional basic passage instruction along X- and Y-planes.  
     CONSTITUTION: When the tapering portion TH having tapering angle θ of work W is machined, a grinding wheel GR is attached on a main spindle SP so as to have tapering angle θ with the axial center of said main spindle θ and subjected to pick-feed S in Z-axial direction at each time of machining motion along X- and Y-planes. At this time, said grinding wheel GR separates from the tapering surface of said work W over a distance corresponding to Δ r = S.tan θ/2 in said X- and Y-planes. If the circumference offsetting value of said grinding wheel GR from passage instruction on said X- and Y-planes is decreased by Δr, therefore, the tapering surface of said grinding wheel GR has comtinuity from that had before said grinding wheel GR is subjected to pick-feed. Thus, said tapering portion TH pf said work W can be ground by said grinding wheel GR.

Title: Petroleum combustion burner
Inventor: UCHIDA TSUTOMU
IPC: F23C99/00
Filed: 1995-01-31
Abstract: PURPOSE: To provide a petroleum combustion burner whose size can be decreased, and whose capacity can be increased and in which the generation of NOx and Co can be lowered. CONSTITUTION: A vaporizing chamber 10 is formed by providing an injection nozzle 5 and a flame holder 7 on the upstream side of a vaporing cylinder 1. Premix gas premixed in the vaporizing chamber 10 is burnt in a combustion chamber composed of a porous medium 11 through inflow holes 8 of the flame holder 7. This combustion causes a through pipe 3 on the downstream side of the combustion chamber and the flame holder 7 on the upstream side thereof to be heated. The combustion gas further heats a heat insulating material 12 provided on the downstream side and in contact with the through pipe 3 and is exhausted from an exhaust port 4. Therefore, a fluid flowing in the through pipe 3 cools the combustion chamber for a low-temperature combustion so that the generation of NOx and Co is suppressed.  The surface area per unit volume in the combustion chamber is increased because of the porous medium 11, so that a combustion load factor can be improved. Thus, the compact burner and large capacity can be achieved.
