IPC: B65H5/02
Filed: 1996-04-30
Abstract: PROBLEM TO BE SOLVED: To provide a medium conveying control device in which the driving current or the applying voltage of a stepping motor can be set selectively, and a conveying means is driven by a driving current or an applying voltage optimum to the respective condition. SOLUTION: To the phase coils 30 to 33 of a stepping motor, a current controlled by a driver 38 to control the driving current of the stepping motor is fed, and the current carrying to the phases of the stepping motor is turned on and off by drivers 34 to 37. Resistances 39 to 42 for current monitoring to detect the feeding currents of the phases are provided between the drivers 34 to 37 of the phases and the GND. A current value detected there is feedbacked to the driver 38. From a controller, the ON and OFF signals of the drivers 34 to 37; a signal to show whether it is within a specific time from the rotation starting of the stepping motor or not; and a signal to show whether a step-out of the stepping motor is generated or not; are delivered.  By making it possible to set a driving current selectively in such a way, the stepping motor can be driven by a driving current optimum to the respective condition.

Title: Apparatus for semiconductor preparation
Inventor: ISHII HIDEO
IPC: H01L21/22
Filed: 1978-10-31
Abstract: PURPOSE:To carry out a gas phase growth under a good following condition to temperature variation without making a wafer in and out, by setting two movable heat furnaces at around a reaction tube. CONSTITUTION:A furnace 4 for high temperature is arranged around a wafer 3 to heat up approximately 900 deg.C, and SiO2 is formed on the Si wafer 3 with introducing O2 and openning valves 6 and 7. Next, a furnace 5 for low temperature is arranged around the wafer by sliding, and let Si3N4 grow with closing valves 6 and 7, introducing NH3 and SiH4 and openning valves 7 and 8. These gas flows do not affect the furnace for high temperature. By so doing, the follow to temperature variation is improved due to release heat between the furnace and the reaction tube by sliding the furnaces for high and low temperatures. Also it reduces the preparation time because the processes at different temperatures are carried out contineously in the same reaction tube.
