23.[解] (1)因为直三棱柱ABCA1B1C1中,

BB1⊥面ABC,∠ABC

B点为原点,BABCBB1分别为xyz轴建立如图所示空间直角坐标系.

因为AC=2,∠ABC=90º,所以ABBC=,

从而B(0,0,0),ACB1(0,0,3),A1C1DE

所以

AFx,则F(,0,x),

.

,所以    

要使CF⊥平面B1DF,只需CFB1F.

=2+x(x-3)=0,得x=1或x=2,

故当AF=1或2时,CF⊥平面B1DF.……………… 5分

(2)由(1)知平面ABC的法向量为n1=(0,0,1).  

设平面B1CF的法向量为,则由

z=1得

所以平面B1CF与平面ABC所成的锐二面角的余弦值

(2)设过Q的直线方程为ykx-1,代入抛物线方程,整理得x2-4kx+4=0.

由△=16k2-16=0.解得k=±1.

于是所求切线方程为y=±x-1(亦可用导数求得切线方程).

切点的坐标为(2,1),(-2,1).

由对称性知所求的区域的面积为S  ………………… 10分
