Filed: 2002-01-25
Abstract: <P>PROBLEM TO BE SOLVED: To accurately detect an error condition in an operation in a recorder even when controlling for allowing a carriage speed to follow a predetermined speed as in feed-back controlling is performed or a moving condition of the carriage is in any condition such as an accelerating condition, decelerating condition, or the like in the controlling of the movement of the carriage.  <P>SOLUTION: An error judgement criterion is set with respect to each of an accelerating condition, a constant speed condition, a decelerating condition, and a stopping condition in the movement of the carriage and each of the judgement criteria is made so as to correspond to respective abnormal condition predicted in each of the conditions. For example, when the position of the carriage is detected and the position is not changed for a predetermined time period, it is judged that an error occurs. When a term that a control amount of a carriage motor is out of a predetermined range is long, it is judged that an error occurs. Thus, it is possible to judge that an error occurs when the carriage is not moving or the load of the motor is increased even when the motor is in the constant speed condition.  <P>COPYRIGHT: (C)2003,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To provide a polymer electrolyte that can improve durability of a fuel cell.  <P>SOLUTION: This is a polymer electrolyte that is characterized by bring made of a polymer material that has an anionic group and a cationic group respectively on the side chain or principal chain on the same or different polymer molecule and is neutralized as a whole.

And it is desirable that the above anionic group and cationic group are nearly ionized. When the anionic group and cationic group which the polymer electrolyte has are nearly ionized, protons of the anionic group move to the cationic group and protons capable of ion exchange become non-existent, thereby ion exchange reaction by metal ion is suppressed and the fuel cell performance is not degraded.  <P>COPYRIGHT: (C)2003,JPO
