IPC: C08L61/00
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To obtain a self-curing binder coated sand grain for mold having rapid hardening speed under specific low temp. atmosphere by using an acid mixing organic sulfonic acid or inorganic sulfonic acid in methan sulfonic acid as an acid setting agent. SOLUTION: The coating sand grain is obtd. by charging the molding sand and the setting agent of the methan sulfonic acid, etc., into a mixer of a sand mill, etc., and adding furan series resin after mixing for several min, and further mixing. The methan sulfonic acid easily isolates sulfonic group even at the time of being low temp. in comparison with paratoluene sulfonic acid and benzene sulfonic acid and has good compatibility with the resin. Therefore, the coated sand grain using the methan sulfonic acid or the acid mixing the organic sulfonic acid or the inorganic sulfonic acid into the methan sulfonic acid, has rapid hardening speed under the low temp. atmosphere, such as <=25 deg.C of room temp. and can shorten the molding cycle. Particularly, even at the low temp., the binder coated sand grain having rapid hardening, high strength and platically extreme available self-curing property is obtd.

Abstract: PROBLEM TO BE SOLVED: To provide a method of controlling a semiconductor device manufacturing apparatus and the semiconductor device manufacturing apparatus that minimizes deviation of reset timing, without interrupting the fetch processing the measured value from a process controller during the process for setting the preset value to the process controller. SOLUTION: In the method of controlling this semiconductor device manufacturing apparatus, an input/output controller 8 interrupts the process to fetch the measured value from the process controller upon reception of an interrupt request 101 for interrupting the input process, unit controllers 7a to 7c discriminate the change of input setting value. When the input setting value is changed, the setting changed requests 105, 107 are output, and when there is no change in the input setting value, the setting value non-change request 106 is output. Thereby, the setting value change requests 105, 107 are output to the corresponding process controller, and when as many change requests 105 to 107 are input as the process controllers from the unit controllers 7a to 7c, the input/output controller 8 restarts the process to fetch the measured value.
