Title: Ink ribbon driving system of printing machine
Inventor: HIKI TOSHIO
IPC: B41J33/52
Filed: 1978-12-15
Abstract: PURPOSE: To maintain nearly a constant tension acted on an ink ribbon regardless of running direction of the ink ribbon by reducing the braking force applied on the  ink ribbon when the ink ribbon runs in a reverse direction of the printing carriage.   
     CONSTITUTION: When an ink ribbon 3 is wound around a spool 4, the more resistance of a resistor 33 develops less braking force applied to the ribbon with a motor 7. When the ribbon 3 is wound around the spool 5, the more resistance of a resistor 34 develops less braking force applied to the ribbon 3 with the motor 6. According, when the motors 6, 7 allow to have the same rating, and the ribbon 3 is wound around the spool 5, that is, running in a opposite direction of a printing belt 1, the braking force acting on the ribbon 3 can be reduced to maintain a constant tension acted on the ribbon 3 regardless of running direction of the ribbon 3 by allowing the resistance of the resistor 34 to set larger value than the resistance of the resistor 33.

Title: Pll frequency synthesizer
Inventor: SATO YUJI
IPC: H03L7/187
Filed: 1988-06-23
Abstract: PURPOSE:To improve the stability and modulation performance, such as pull-in time, noise band width, etc., of the title synthesizer by actuating a PLL circuit performance changing means which switches a loop inherent frequency of a prescribed value to a larger value by means of a frequency changing means for a prescribed period. CONSTITUTION:In the normal state, switches S1 and S2 of the loop filter 20 incorporated in this PLL frequency synthesizer are controlled to opened states. Therefore, the loop inherent frequency of a PLL circuit goes to a relatively small value omegaL and the stability of the synthesizer in noise band width, etc., becomes extremely excellent. When the frequency of the output frequency fo of the synthesizer is changed, the switches S1 and S2 of the loop filter 20 are simultaneously closed with the input of a frequency switching timing signal and the loop inherent frequency is changed to a relatively large value omegaH. Therefore, the pull-in time of the PLL frequency synthesizer can be shortened and the synthesizer can be immediately stabilized with a new oscillation frequency.

Title: Electronic equipment with display density control function
Inventor: SUHARA NAOKI
IPC: G06F3/0484
Filed: 1997-06-13
Abstract: PROBLEM TO BE SOLVED: To easily perform density setting even when the contents of picture can not be confirmed. SOLUTION: When a setting mode for setting the display density is provided in one of setting menus and the density setting mode is selected through the selection of setting menu, the mode is transited into density setting mode in the state of forcedly changing the density on a display part to the density of halftone. Namely, when only a key for menu selection can be confirmed, only by repeatedly operating this key several times, the setting menu for setting the display density is selected without fail.  Since the mode is transited to the display density setting mode after the display density is forcedly changed to the display density of halftone when this setting menu is selected, however the previous set density is controlled to any extreme density, the mode can be transited to this density setting mode in the state of control into density so as to confirm the display contents of picture. Even when the display density is erroneously set extreme, such a state can be easily canceled.
