Abstract: PURPOSE:To maintain feed quantity of an ink sheet to be constant by detecting a feed quantity of the ink sheet corresponding to a predetermined driving quantity for feeding the ink sheet, and controlling the driving quantity when the feed quantity is different from the driving quantity. CONSTITUTION:For example, when a current in phase A is a1 and a current in phase B is b1, a rotor is rotated clockwise by 360/256 deg., and a stopping position for the rotor can be controlled with the angle value as a unit. A photo- sensor 71 detects stripes 72 printed at predetermined intervals on an ink sheet 14 on the side opposite to an ink-coated side, and thereby detects feed quantity of the ink sheet 14. A counter CNT counts the number of exciting steps for driving an ink sheet-feeding motor 25 over the period from the detection of the first stripe to the detection of the next stripe. A skip value (m) indicating the number of current values to be skipped over in specifying the current values is determined based on the count on the counter CNT, and the value of (m) is regulated, thereby controlling finely the feed quantity of the ink sheet 14.

IPC: G01N27/333
Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To raise stability of selectivity of an anion selectivity electrode based on an anion exchange resin film. SOLUTION: Regarding an anion selectivity electrode based on an anion exchange resin film, which is a covalent bond of quaternary ammonium salt to a polymer, an anion for improving selectivity is formed in an entwined condition to an anion exchange resin film as a polymer.

Title: Magnetic head
Inventor: MIURA YOSHIMASA
IPC: G11B5/127
Filed: 1986-10-20
Abstract: PURPOSE:To improve the mechanical strength of a center rail and to reduce deteriora tion in the quality of a reproduction signal, by providing a gap part which regulates a recording and reproducing track width within the rail width of the center rail having a medium track width larger than that of a floating slider. CONSTITUTION:Width W2 on a core inflow end 31a side for a medium traveling direc tion at the gap 34 part is formed larger by 1-5mum than width W1 on a core inflow end 33a which regulates a confronting reproducing track width. Therefore, when a bit of information is recorded on a magnetic disk medium, normal recording is performed on the core inflow end 33a side for the medium traveling direction with narrow width at the gap part 34, however, at this time, a considerably strong leakage magnetic field is generated at the gap facing plane of the core outflow end 3a with wide width confronting with the core inflow end 33a interposing the gap 34, thereby, the medium is magnetized. Also, since the reproduction of the bit of information is performed on the core inflow end 33a side with narrow core width, it is possible to record the bit of information in wide track width, and to reproduce it in the track width smaller than the above track width. In this way, the deterioration in the quality of the reproduction signal by a thermal off track can be remarkably reduced.

Abstract: PROBLEM TO BE SOLVED: To input characters easily and speedily and improve the operability by performing input operation with character keys of the Japanese syllabary when the frequency of a failure in the recognition of an inputted character exceeds a specific value. SOLUTION: A character recognition part performs character recognition for a character pattern showing an array of position information inputted to a character input part by referring to a dictionary for character recognition and sends the result to an interactive management part (S45).
