In a method of fabricating a variator disc, an outer periphery (5) of the input disc (D1), with a spline hole (4) thereof meshed with an input shaft (6), is finished using the input shaft (6) as a working reference. Subsequently, a race (2) is finished with high precisions using the outer periphery (5) as a working reference. There is an alternative method wherein a spline hole (4) with a machining allowance is precisely formed by means of a broach (X) prior to the heat treatment of a blank (B); after hardening the blank (B) by the heat treatment, tooth flanks (4a) of the spline hole (4) are precisely finished by means of a finishing broach (Y); and then, a race (2) of an input disc (D1) is precisely finished using the tooth flanks (4a) as a working reference.
摘要:
The user observes a liquid crystal display panel screen positioned within a lens barrel through a lens. An infrared LED that emits pulses of light and a phototransistor are positioned in an eyecup against which the user's eye is pressed. An ambient light detecting circuit provides a control signal showing whether or not the user's eye is pressed against the eyecup and a control signal showing the amount of ambient light on the basis of the output signal of the phototransistor. A control circuit controls the luminance of a backlight unit according to the control signals. When the user's eye is not pressed against the eyecup, the display luminance is reduced to zero and the display is turned off. The display luminance is enhanced only when the amount of ambient light is large. Thus, needless power consumption can be avoided, and the screen can be satisfactorily observed even if a large quantity of light enters into the ocular part where the ambient light is bright.
