Title: Dish washer and method for operating the same
Inventor: OTSUKA TOSHIHARU
IPC: A47L15/46
Filed: 1997-11-18
Abstract: PROBLEM TO BE SOLVED: To compensate that the changeover of circulating and draining operations is independent of the turning on/off of a pump in a mechanism. SOLUTION: SW1 and SW2 are compensated to be operated by different steps. Even when the contact point of NC and NO in SW2 is turned on owing to a fault, etc., for example, SW1 is not closed in the state so that an overcurrent is not made to flow in a driving circuit without admitting of the occurrence of excessive heat generation. That is, the on/off steps of motor driving by SW1 and the changeover step for circulating pump driving and draining pump driving by SW2 are controlled as an individual step so that it is compensated that the changeover of the circulating and draining operations, that is, the changeover of reversal revolution is independent of the turning on/off of the pump in the mechanism. Then, a current being more than permission in a capacitor motor 1 is prevented from flowing and the fault owing to motor seizing, etc., is also prevented.

IPC: H01L21/205
Filed: 1990-11-22
Abstract: PURPOSE:To suppress the boosting of pressure in a reaction chamber due to the overshoot phenomenon of a gas flow-rate controller, and to prevent excessive progress of chemical reaction by a method wherein a turbine-like resistor is provided in the midway of the gas-introducing tube between a gas flow-rate controller and the reaction chamber. CONSTITUTION:When a treatment is conducted by introducing film-forming gas into a reaction chamber 5 containing the wafer to be treated, an overshoot phenomenon, in which gas flow rate will exceed by far instantaneously the preset flow rate in the first stage of gas introduction, is generated. The gas came out from a controller flows out vigorously, but when it reaches a turbine- like resistor 9, the gas comes in contact with the turbine vane 11, the force of gas is weakened, and the turbine rotates shlowly. At this time, the pressure in the chamber does not boost suddenly by the overshoot phenomenon. Accordingly, the chemical reaction does not make a progress too much in the early stage of gas introduction, and no secondary product is generated.
