Title: Frequency determination method for constant voltage ac fed to torque sensor detection coil
Inventor: ONODA JUN
IPC: G01L3/10
Filed: 1995-12-08
Abstract: PROBLEM TO BE SOLVED: To lessen sensor characteristic dispersion without any change of sensitivity by determining the frequency of constant voltage alternating current fed to a detection coil, so as to minimize the fluctuation of the impedance change rate of the detection coil for an axial change in the relative position of upper and lower sensor ring teeth. SOLUTION: An upper sensor ring 21 and a lower sensor ring 22 are coaxially arranged at the prescribed radial gap, so as to be faced to each other for maintaining the axial superposed length (overlapped length) of tooth parts 21a and 22a at the prescribed value. Also, the sensitivity of a detection coil 25 increases, according to a drop in the frequency of supplied constant voltage alternating current, and lowers, according to an increase in the frequency.  In this case, therefore, the frequency of the constant voltage alternating current fed to the coil 25 from an oscillator is set at such a value as capable of minimizing the fluctuation of sensitivity for the change of the overlapped length of the tooth parts 21a and 22a, thereby reducing the dispersion of a sensor characteristic due to the axial irregularity of the relative position of the sensor rings 21 and 22 resulting from an assembly error or the like.

Title: Serial printer and recording medium with program recorded
Inventor: ORII SATORU
IPC: B41J5/30
Filed: 1999-11-11
Abstract: PROBLEM TO BE SOLVED: To provide a serial printer which can print at a speed higher than conventional ones by promptly processing characters, and a recording medium in which a program for controlling a printer is recorded.

Title: Voltage control method for electric field radiating electron gun
Inventor: NORIOKA SETSUO
IPC: H01J37/248
Filed: 1988-12-20
Abstract: PURPOSE:To set the emission current Ie accurately to a specified value and hold it by comparing the sensing value for the current I1 with the set value of current Ie in the range in which the emission current Ie is equal to the pullout electrode current I1, and thereupon performing voltage control. CONSTITUTION:At first the heating voltage V0 is set to 0 by a means 14, and the pullout voltage V1 is raised by a means 15 gradually. Because at this time the pullout electrode current I1 is substantially equal to the emission current, sensing is made by a means 16 followed by fixation where the I1 is equal to the setting value of Ie, and finally a means 14 causes rising to -V0 as specified. To restore dropped Ie, first -V0 is depressed until V1>1-V01 is established and held there, followed by rise of V1 by a means 15 so as to recover Ie, and finally -V0 is restituted to the specified value by the means 14. This constitution enables certain setting and holding of the emission current at a specified value, which has been impracticable substantially according to any conventional arrangement.
