| 20120132391 | METHOD FOR GREEN SAND MOLDING - The object of the present invention is to provide a method for green sand molding that prevents a bad casting by producing a mold that does not have a brittle surface. The method comprises the steps of filling the green sand into a flask while fluidizing the green sand by aeration at a pressure between 0.05 and 0.18 MPa, and squeezing the green sand that has been filled in the flask, wherein a mold is produced so that the friability of the mold is 10 or less. The friability is a value that is calculated by the following steps: putting the mold in a rotating cylindrical sieve that has a diameter of 177.8 mm and USA sieve size No. 8, rotating the cylindrical sieve at 57 rpm for 60 seconds, dividing the weight of the sand that has passed through the sieve by the weight of the sand that has been put into the sieve, and multiplying the quotient by 100. | 05-31-2012 |
| 20120085465 | CARBURIZED COMPONENT AND MANUFACTURING METHOD - A carburized component with improved fatigue strength has a base steel containing, by mass %, C: 0.15-0.25%, Si: 0.03-0.50%, Mn: more than 0.60% and not more than 1.5%, P≦0.015%, S: 0.006-0.030%, Cr: 0.05-2.0%, Al≦0.10%, N≦0.03%, and O≦0.0020%, and optionally at least one element selected from Mo, Cu, Ni, B, Ti, Nb and V, the balance being Fe and impurities. A surface hardened layer portion satisfies: (a) average carbon concentration in the region from the outermost surface to a point of 0.2 mm depth of 0.35-0.60 mass %, (b) surface roughness Rz≦15 μm, and (c) σr(0)≦-800 MPa, σr(100)≦-800 MPa, and residual stress intensity index Ir≦80000, wherein Ir is calculated by [Ir=∫|σr(y)|dy], where y μm is the depth from the outermost surface and σr(y) is the residual stress for the points from the outermost surface to a depth of 100 μm with the range of y from 0 to 100 (μm). | 04-12-2012 |
| 20120041588 | SYSTEM AND A METHOD FOR REMOTE ASSISTANCE IN A FOUNDRY - The object of the present invention is to provide a remote assistant system for a foundry, i.e., a plant that comprises a plurality of machines. The remote assistant system in a foundry includes a first sequencer for controlling a molding line and a second sequencer for controlling a molding machine. It further includes a sequencer-communicating means for connecting the first sequencer to the second sequencer, a first mobile computer for transmitting information by video images, etc., to a remote location, a means for providing communication between mobile computers to selectively connect one of the sequencers to the first mobile computer, a second mobile computer for receiving the information from the first mobile computer, for displaying the information, and for correcting the ladder logic program and giving instructions to the operator by an assistant at a remote location. | 02-16-2012 |
