A pair of tappets(412) is located inside the cylinder head and faced to stem ends(211,221) of valves(210,220). Thereby, a valve included angle(A) by the intake valve and the exhaust valve is reduced. Therefore, the size of the cylinder head is reduced.

Title: Deflection yoke of brown ray tube
Inventor: YOON SEUNG CHAN
IPC: H01J29/76
Filed: 2002-03-06
Abstract: PURPOSE: A deflection yoke is provided to achieve improved deflection sensitivity by enhancing the shape of the deflection coil, while allowing for ease of correction of distortion. CONSTITUTION: A deflection yoke comprises a horizontal deflection coil(162) coupled to the rear end of a cathode ray tube through a ring band and mounted along the circumference of an aperture so as to deflects an electron beam in a horizontal direction; a vertical deflection coil(164) fixed in rear of the horizontal deflection coil through a holder so as to deflect an electron beam in a vertical direction; a ferrite core arranged in rear of the vertical deflection coil, and which reduces losses of the magnetic force generated by the current of the horizontal and vertical deflection coils; a magnet arranged along the circumference of the aperture so as to correct distortions on a screen; and an inclined portion(30) formed by permitting a neck side flange(10) or an aperture side flange(20) of the deflection coils to have different thicknesses in a circumferential direction.
