摘要:
A contact sensor capable of inputting a character by tracing a character with user's finger is arranged in a region of a ten-key unit of a mobile telephone. When registering a password to release a key lock, a user traces a shape of a line, a character, a number, or other symbol on the contact sensor with his/her finger so that the shape is inputted and stored in a memory, thereby completing registration of a password. When releasing the key lock, the user traces the registered shape on the contact sensor with his/her finger so that the key lock is released. The input is easy. Even if the password input operation is observed by a third person, the password will not be easily known to the third person.

摘要:
The purpose of the present disclosure is to provide a sealed battery that can expand a joint area of an electrode lead with respect to a sealing body or the like without using a large-width electrode lead. A sealed battery, which is an example of an embodiment, comprises: an electrode body having an electrode lead; a bottomed tubular exterior can that accommodates the electrode body; and a sealing body that plugs an opening section of the exterior can. The electrode lead is welded, with energy beams, to the inner surface of the sealing body. In addition, the electrode lead includes: a first main surface making contact with the inner surface of the sealing body; and a second main surface on the opposite side of the first main surface, wherein the first main surface and the second main surface are formed in no-parallel with each other.
