Inventor: HARUNA SHUJI
IPC: H01H13/14
Filed: 2001-02-23
Abstract: PROBLEM TO BE SOLVED: To provide a switch mechanism capable of preventing breakage of a hinge part without impairing operation feeling. SOLUTION: When an operation part 2010 is pressed by force larger than pressing force for an operation member 20 for turning on/off a pressed part 1006 as shown in Figure 1 (C), the operation member 20 is further rocked rearward as compared with the case of Figure 1 (B) by using the hinge part 2004 as a fulcrum.

Title: Liquid treating apparatus and method
Inventor: YAGI YASUSHI
IPC: C25D21/08
Filed: 2001-02-26
Abstract: PROBLEM TO BE SOLVED: To provide a liquid treating apparatus which ensures the electrical contact which supplies electricity and surely seals the electrical contact from the treating liquid, and to provide the liquid treating method. SOLUTION: The sealing state of peripheral part of the object to be treated which is in electrical contact with a contact member which is disposed on a part holding the object to be treated is maintained until the part holding the object to be treated is retreated from the upper part of the treating vessel by a transporting mechanism. After the treatment, the treated surface of the object to be treated is washed. Therefore, without regarding the contamination of the washing liquid to the treating liquid, the treated surface and the part holding the body to be treated can be adequately washed by a washing mechanism which is different from the treating vessel.  In addition, the washing mechanism can be disposed on a place different from the treating vessel and, thereby, an atmosphere in which the washing is performed is easily made to be a space in which there is no mist of treating liquid. As a result, even when the sealing state is opened, the contamination to the contact member and the sealing member which are disposed on the part holding the object to be treated is extremely reduced.
