Abstract: PURPOSE:To shorten processing time for interpolating operation and to eliminate the necessity of a large capacity non-volatile memory by interpolating between plural set data by high degree interpolation and interpolating between the high degree interpolation data and the set data by low degree interpolation data. CONSTITUTION:At the time of setting on a registration adjusting mode, a CPU 10a executes initial registration adjustment, generates set data, writes the data in an EEPROM 10b, reads out the set data from the EEPROM 10b, and interpolates between the set data by generating high degree interpolation data by high degree interpolation operation. When the high degree interpolation data are stored in the EEPROM 10b, the CPU 10a generates low degree interpolation data based upon both the data set by an arithmetic circuit 10f and the high degree interpolation data and interpolates between the set data and the high degree interpolation data by linear interpolation. Then the set data from the EEPROM 10b, the high degree interpolation data and the low degree interpolation data are converted into analog data and outputted as a corrected waveform.

Title: Method for driving bimorph type electrostrictive vibrator
Inventor: SATOU FUMIO
IPC: B06B1/06
Filed: 1980-10-23
Abstract: PURPOSE:To obtain larger displacement and energy, by noticing the polarization state of a piezoelectric element. CONSTITUTION:A power source V1 is applied only to one side of a piezoelectric element to give an auxiliary displacement. This electric field can be applied up to Emax because of the forward direction. A displacement quantity Y1a at this time becomes 3/4h.d31 Emaxl<2>. At the time when an electrostrictive element 3 is operated, the part of the element 1 is short-circuited, and the power source V1 is applied to the part of a piezoelectric element 2, and the sag becomes Y1=Y1a+Y1b= 3/4h.d31 Emaxl<2> similarly. Consequently, displacement Y1=Y1a+Y1b=3/4h.d31  Emaxl<2> is obtained. Therefore, a displacement twice as large as the displacement  due to the conventional driving method is obtained in respect to materials which satisfy Emax=4Ep. In said equations, (l) and (h) are the length an the thickness of  the vibrator, and d31is a piezoelectric constant.

Abstract: PROBLEM TO BE SOLVED: To reduce changes in paper carrying speed, even if a carrier roller of recording paper is affected by radiation heat, in an ink jet printer using a heat fixing method for drying ink particle on recording paper. SOLUTION: A carrier roller 10 and a driven roller (star roller) 11 are arranged in the vicinity of an ink drying part and are heated by heat of the drying part. Because a material of the carrier roller 10 is soft and a rotary shaft of the carrier roller 10 and a rotary shaft of the driven roller 11 are kept at a fixed interval by a positioning and fixing member, the surface of the carrier roller 10 is pressed by the driven roller 11 and is recessed when the carrier roller 10 thermally expands. By using a material of a small coefficient of thermal expansion as the material of the carrier roller 10, an increase in a diameter of the carrier roller 10 can be suppressed and an increase in paper carrier speed can be reduced.

Filed: 1995-05-25
Abstract: PURPOSE: To cancel axial thrust as a whole by a structure wherein axial slots are made in parallel in the stator such that the rotor pole becomes symmetrical with respect to the rotary shaft and the paired poles have trapezoidal shape directing reversely. CONSTITUTION: A rotor 11 are arranged with poles 13, 15 and 14, 16 at four symmetric positions around a rotary shaft 12.
