Title: Crucible for manufacturing wide quenching solidifying thin stripe
Inventor: SATO YUICHI
IPC: F27B14/10
Filed: 1990-05-23
Abstract: PURPOSE:To prevent deflection even if the number of nozzle openings is increased, and to perform a stable mass production without increasing a melting time by providing the nozzle openings for injecting melted metal in a bottom in an elliptical or rectangular section in a depth direction. CONSTITUTION:In order to prevent deflection of a crucible generated when making a wide quenching solidifying thin stripe, nozzle openings for injecting melted metal are provided in a bottom in an elliptical or rectangular section in a depth direction. It is desired to set the length of a long side to 300mm or longer as the size of the section in the depth direction of the crucible. If the length of the long side of the crucible is 300mm or longer, the length of a work coil 2 at the short side is set to 130mm or longer so as to suppress the deflection of the bottom of the crucible at the time of melting a sample. Then, it takes a time to melt the sample, and does not achieve the purpose of this invention. Therefore, it is desirable to set the length of the short side of the crucible to 100mm or less.

Filed: 1994-06-15
Abstract: PURPOSE:To reduce cost and to prolong the life of a backup battery. CONSTITUTION:This programmable controller is equipped with a dedicated CPU unit 1 which executes a sequence program and a main CPU unit 3 which performs other processes. When a power source of the programmable controller is turned OFF, data for arithmetic stored in a 2nd memory 5 are transferred by DMA to a work area in a 1st memory 4 and saved. A 1st memory 4 consists of a static RAM and its memory contents are backed up by the backup battery 9. The contents of the 2nd memory 5 need not be backed up by the backup battery 9 and the 2nd memory 5 can be composed of an inexpensive dynamic RAM. The cost of the programmable controller is therefore reduced and the current consumption of the backup battery 9 is reduced to prolong the life of the battery.
