Title: Control system for power supply
Inventor: MARUOKA HIROSHI
IPC: G06F1/00
Filed: 1985-11-22
Abstract: PURPOSE:To obtain a power supply control interface corresponding to a small- scale system by using three common signal lines, a connection signal line and two switches to control a power supply interface set between processors. CONSTITUTION:When the power supply of a main controller is applied, the application instructing signal is sent to a connection adaptor 2-1 concurrently with the rise of a shared power supply Vcc. Receiving this signal, the adaptor 2-1 applies the power supply of a device to be controlled. Then the power supply application end signal is sent back from the device to be controlled. Thus the adaptor 2-1 turns off and on the transistors Tr1 and Tr2 respectively. The common part of a switch SW2 is connected to the Tr2 and therefore it is decided that the device to be controlled which must be applied to a lower stage still exists as long as the switch SW2 is connected to the side (a). Then the application instructing signal is transmitted to the lower stage and it is known that all power supplies are applied when the SW2 is connected to the side (b). Then the application end information signal is sent back to the main controller. Thus the main controller starts a system operation.

Filed: 1995-09-18
Abstract: PROBLEM TO BE SOLVED: To provide a depressurizing method wherein time it takes to reach a target pressure value is reduced and particles can be easily discharged from chambers. SOLUTION: To reduce the pressure in a process module PM1 from atmospheric pressure to 1000Pa, both an exhaust-side valve PV and a supply-side value V are opened, and while a vacuum pump VP is being operated, N2 gas is supplied from a gas controller 14. The process module PM1 is purged using N2 gas, and further is depressurized by means of the vacuum pump VP. In the process module PM1, a N2 gas flow going from the ceiling to the bottom is formed. As a result, oxygen and moisture in the process module PM1 due to atmospheric pressure is discharged by the N2 gas flow. Particles are also discharged. The flow rate of the N2 gas is controlled to 20 or so. The internal pressure is detected using a pressure sensor, and when the detected pressure reaches a target value, the valves V and PV are closed to stop purging. Then the operation of the vacuum pump VP is stopped.
