Filed: 2000-07-11
Abstract: PROBLEM TO BE SOLVED: To provide a washing method for business use effectively preventing the shrinking and damages of laundry at the time of performing washing for the business use with water as a main body, and a washing device used for it. SOLUTION: Air bubbles are introduced from below of the laundry put inside a washing tub 10 and the operation of the washing tub 10 is controlled so as to be based on a standstill state. Thus, by the elevating action of the air bubbles, washing using the water and a detergent becomes more effective. That is, fine air bubbles pass through the laundry from below and thus the water and the detergent also pass through the laundry accompanying the movement of the air bubbles. Also, the laundry is not moved by adding mechanical force for washing and the operation of the washing tub is controlled so as to be based on the standstill state.

IPC: H04N1/10
Filed: 2000-07-17
Abstract: PROBLEM TO BE SOLVED: To provide an image reader by which the vibration of a driving shaft due to the overshooting of a stepping motor can be suppressed. SOLUTION: When the driving of the stepping motor 8 is switched from a full step to a quadripartite step by a driving controlling plate 21 after passing specified time since the speed of respective carriages 1 and 2 reaches specified speed, a motor driving pulse number becomes four thousands and some hundreds, and a moving amount is set as 0.72/4=0.18 deg., and the vibration of the driving shaft 4 is reduced because the moving amount per one step is small, and the overshooting by the stepping motor 8 can be suppressed, so that speed fluctuation can be reduced. In the case that the respective carriages 1 and 2 are moved in the same distance, since the stepping motor 8 is moved in a short time rather by the full step, it is moved by the full step to the vicinity of a reading start position, and one reading time is made as short as possible, so that cpm improvement can be attained.
