Title: Recorder and recording method
Inventor: MIYAZAKI AKIHITO
IPC: B41J2/32
Filed: 1998-05-13
Abstract: PROBLEM TO BE SOLVED: To lead a recording material flying from a transfer section to a body being transferred by applying an electric field between them such that the recording material flying from the transfer section is attracted to the body being transferred. SOLUTION: When a DC voltage having absolute magnitude of 100 V or above is applied from a DC power supply 10 between a conductive support, i.e., an electrode 6, to be arranged with a print sheet 3 and a conductive support, i.e., an aluminum base 4, to be formed with a transfer section 1, an electric field for attracting ink 2 to a photographic printing paper is generated in the flying region of ink 2. When a positive potential is applied to the electrode 6 and the print sheet 3 is brought into positive potential, ink flying from the transfer section 1 is charged negative because the transfer section 1 is brought into negative potential by earthing the aluminum base 4 to an earth part 11.  The ink 2 flying through surface tension convection is thereby subjected to vaporization or ablation at the transfer section 1 and electrostatic force acts thereon thus leading the ink 2 to the print sheet 3.

Title: Thermal transfer recording method
Inventor: KUNITAKE TETSUJI
IPC: B41J2/355
Filed: 1985-06-18
Abstract: PURPOSE:To prevent a recording paper from being contaminated immediately after the start of recording, without reducing a driving force of a recording head, by a method wherein energization of a driving member is stopped at least one time before a recording head is moved from a non-printing position to a printing position, and thereafter energization is restarted. CONSTITUTION:When a solenoid is energized at a recording-starting time T0, the recording head is started moving to the printing position. When the energization of the solenoid is stopped at time T1, the head is moved toward the printing position under inertia, but it is gradually decelerated to be stopped by a restoring force of the spring. When the solenoid is again energized at time T3, the head is again moved under acceleration toward the printing position, and reaches the printing position at time T4. Since the period of time T4-T3 is short, the velocity of the head at the time of reaching the printing position is low, so that an impact force is small, and the recording paper is not contaminated. Thereafter, energization of the solenoid is continued to time T5, thereby printing, and when the energization is stopped, the head is returned to the non-printing position by the restoring force of the spring.

IPC: G06K7/10
Filed: 1981-08-21
Abstract: PURPOSE:To perform complicated correction of optical length with high accuracy, by mechanically separating a driving system of an optical length correcting means from that of a rotating mirror. CONSTITUTION:A main scanning is performed by a one-dimension image sensor 11 and a sub-scanning is performed by a rotating mirror 3. The center of the mirror 3 is provided beneath the left end of the range of the sub-scanning. In this case, the left side of the range of sub-scanning has larger rotating angle of the mirror 3 required for the sub-scanning per unit length than the right side.

Title: Monaural/stereo discriminating device
Inventor: KAKU JUNYA
IPC: H04H1/00
Filed: 1995-05-30
Abstract: PURPOSE: To clearly discriminate between monaural and stereo by deciding whether the ratio of the difference signal of the signals of the both of left and right channels and the sum signal of the signals of the both of the left and right channels is a reference value or above or not. CONSTITUTION: In input terminals TL and TR, digital voice signals of two channels are inputted. A difference signal calculation part 11d calculates the difference of the both of left and right channels and a sum signal calculation part 11s calculates the sum of the both channels. Filters 12d and 12s pass only specified frequency areas and eliminate the erroneous decision factor signal of the signal of the band in which the change of amplitude is sharp. Time addition parts 14d and 14s output S5d and S5s that the absolute values outputted via absolute value calculation parts 13d and 13s are converted for fixed time. A comparison part 15 determines the value S6 that the signal S5s multiplied by a constant Ac is subtracted from the signal S5d . In the case of S6>0, the channel is decided as stereo. In the case of S6<=0, the channel is decided as monaural.  Namely, the decision is performed according to whether the ratio of S5d /S5s exceeds the constant Ac or not. An acoustic processing part 4 gradually performs the switching of monaural and stereo.
