Title: Driver of objective lens
Inventor: MATSUNO TOSHIKI
IPC: G02B7/28
Filed: 1982-10-08
Abstract: PURPOSE:To control accurately the position of an objective lens, by coupling a connecting member for yoke vibration prevention to an upper open end of a magnetic yoke formed in channel shape, and enclosing the upper open end of the yoke to decrease the sound of a driver. CONSTITUTION:A quadrangle frame is formed with the yokes 4a, 4b and the connecting members 7a, 7b. The vibration of the yokes 4a, 4b is blocked and the frequency peak of the unpleasantest sound at the driving of an objective lens is reduced by about >=10dB. Further, the vibration of the yokes 4a, 4b and the permanent magnets 5a, 5b is blocked, the magnetic field formed with the permanent magnets 5a, 5b and the yokes 4a, 4b is stable without oscillation allowing to control accurately the objective lens in terms of time and space. Moreover, no magnetic field is oscillated, unnecessary oscillation of the objective lens 1 is eliminated, an abnormal oscillation in an electric circuit for position control of the objective lens 1 using a reflected light from the disc is prevented and the gain control range is extended by about >=20dB.

Abstract: PURPOSE:To reduce a cost and to miniaturize a press die by forming a side pin holding part and engagement part with the material having an affinity at the pouring time with a cast iron and having a high stiffness and pouring integrally with the main body part made of cast iron. CONSTITUTION:The reinforcing material 16 consisting of a steel is fixed by plural bolts 20, 18 to the main body part 10, a side pin 32 is penetrated through holes 30, 26, a plate 38 is engaged alternatively with the annular grooves 34, 36 thereof and the pin 32 is fixed. The reinforcing material 46 consisting of a steel is similarly fixed by a bolt to the main body part 44 of a pressing pad 42. The main body parts 10, 44 are made of cast iron, the reinforcing materials 16, 46 are formed by a cast steel or special steel and the main body part and reinforcing material are integrally poured after machining the abutting face in advance. Since the impact load of the case of the pin 32 engaging with the blind part 56 of a groove 50 is received by the reinforcing material having a big strength, the whole die body is miniaturized and the cost can be reduced with the standardization of the reinforcing material.
