Power supply system, power supply method and lot processing method
First Claim
1. A power supply system comprising:
- a processing unit,a power supply unit which supplies power to the processing unit,a lot specifying portion which specifies a state of a lot to be processed by the processing unit,an arrival time calculating unit which calculates arrival time taken for the lot to arrive at the processing unit from a present position based on the state of the lot,a comparing portion which compares the arrival time with start-up time of the processing unit, anda supply control portion which controls the power supply unit to supply operation power used to operate the processing unit to the processing unit when the arrival time is not longer than the start-up time and supply saving power which is smaller than the operation power to the processing unit when the arrival time is longer than the start-up time.

Abstract
A power supply system is disclosed. The system includes a power supply unit which supplies power to a processing unit, an arrival time calculating portion which calculates arrival time taken for a lot to arrive at the processing unit from a present position based on the state of the lot, a comparing portion which compares the arrival time with start-up time of the processing unit, and a supply control portion which controls the power supply unit. The supply control portion causes operation power to be supplied to the processing unit when the arrival time is equal to or shorter than the start-up time and causes saving power which is smaller than the operation power to be supplied to the processing unit when the arrival time is longer than the start-up time.

11. A lot processing method comprising:
-
specifying a state of a lot to be processed by a processing unit, calculating arrival time taken for the lot to arrive at the processing unit from a present position based on the state of the lot, comparing the arrival time with start-up time of the processing unit, supplying operation power used to operate the processing unit to the processing unit when the arrival time is not longer than the start-up time, supplying saving power smaller than the operation power to the processing unit when the arrival time is longer than the start-up time, and processing the lot by use of the processing unit. - View Dependent Claims (12, 13, 14, 15)
