Patent JP-H0429865-A (JP)
Title: Printer
Inventor: TERAJIMA YUJI
IPC: B41J11/38
Filed: 1990-05-25
Abstract: PURPOSE:To reduce the resonance of a platen knob disposed outside an outer case to reduce a noise caused by the resonance by a method wherein the platen knob for rotating a platen from the outside of the case is mounted on the platen through an elastic member. CONSTITUTION:When a printing head 1 conducts a printing action, a printing wire impacts on a platen 3, and the ink of an ink ribbon is transferred to recording paper 2 by this impact energy. Because the impact energy is large and the number of printing wires is large, the platen is excited to vibrate largely. The vibration of the platen 3 is transmitted to a platen knob 12 through a platen shaft 3a. However, because an elastic member 11 is provided between the platen shaft 3a and the platen knob 12, the vibration energy of the platen 3 is converted to a thermal energy, and the vibration energy to be transmitted to the platen knob 12 is reduced to a large extent. Therefore, the resonance of the platen knob 12 when the printing head 1 conducts a printing action is reduced, and a noise is remarkably reduced.

Title: High voltage generating device
Inventor: TANI KEIJI
IPC: H02M9/00
Filed: 1978-11-08
Abstract: PURPOSE: To control rising of current of a load circuit, by dividing a DC circuit breaker into a given number of steps to be connected in series, turning them into a module form and changing voltage generated on a coil while switching in turn time constant regulating resistance by thus modulated DC circuit breaker.  
     CONSTITUTION: A changeover switch 3 is turned on to side a, and an energy- accumulating coil 9 is excited by a power source 1. When main thyristers 23 through 25 are ignited, a current 18 of the coil flows through the main thyristers 23 through 25. And as the current passing through the changeover switch 3 then becomes zero, the changeover switch 3 becomes opened. Now, when an auxiliary thyrister 6 of a commutation circuit 14 is ignited, a commutation capacitor 4 discharges electricity, and therefore, the main thyristers 23 through 25 become OFF. The coil current 18 passes through time constant regulating resistances 22,21 and 20, and the commutation capacitor 4 is conversely charged. A voltage is induced into a plasma generating circuit 10 electromagnetically combined with the energy-accumulating coil 9, and an electric discharge is started.
