Title: Control device for vehicle and radiation noise reducing method of control device for vehicle
Inventor: ISHIHARA HIDEKI
IPC: F02D45/00
Filed: 1998-02-26
Abstract: PROBLEM TO BE SOLVED: To reduce radiation noise from a control device for vehicle without adding parts. SOLUTION: Of wiring patterns formed on a printed wiring board 43 of a control device 41 for vehicle, wiring patterns P5 , P6 connect a base terminal of a transistor 19 driving an actuator and an output terminal o1 of an IC 13 for control via a resistor 25 for limiting base current. The resistor 25 is mounted in the vicinity of the output terminal o1 of the IC 13 for control and on the side of the output terminal o1 of a location where the wiring patterns P5 , P6 are crossed with an other wiring pattern P2 or a location where the wiring patterns P5 , P6 approach an other wiring pattern P8 most. Therefore, high frequency noise generated from the output terminal o1 of the IC 13 for control is damped just near the output terminal o1 and noise induction to other wiring patterns can be suppressed.  As a result, noise radiated from the device 41 to the outside via a wire harness 3 can be reduced.

IPC: B41J1/54
Filed: 1981-03-30
Abstract: PURPOSE:To prevent dirty printing even though a typing wheel is miniaturized in the typing wheel of the compact printer wherein the printing is performed with the types being protruded, by arranging elastic ring bodies between the inner surface of a cylindrical base plate and the edge part of the type. CONSTITUTION:When a force is applied to a protruded part 5d by a hammer 4, a type body 5 is moved, and the printing is performed. Since the types 5 and 5' are not linked, the neighboring type 5' is not affected, and the dirty printing is not caused by the neighboring type 5'. Since the ring bodies L which are inserted between the protruding end part of 5d and the inner surface of the base plate 2 is made of an elastic body, they are compressed at the time of printing, and the type body is returned to the original position by the restoring force at the end of printing. Even though applying ink is infiltrated between a seat part 5b and the base plate 2, tacky adhesion is hard to occur since the contact area between the seat part 5b and the base plate is small.
