Patent JP-S642417-A (JP)
Title: Frequency divider
Inventor: YAMASHITA SHINJI
IPC: H03K23/00
Filed: 1987-06-24
Abstract: PURPOSE: To preclude the skew between a signal after frequency division and an original signal by generating 1/2-frequency-divided signals by a frequency dividing circuit at each timing which is 0 and π/2 each out of phase with the input signal, ORing the two frequency divided signals which differ in timing exclusively, and regenerating a signal similar to the frequency of the input signal.  
     CONSTITUTION: This frequency divider consists of 1st and 2nd frequency dividing circuits 1a and 1b which output frequency signals a half as large as the input signal, an inverter circuit 2 which outputs the inverted signal of the input signal, and a two-input exclusive OR circuit 3. The exclusive OR output signal f 2  between the output signal f 3  of the frequency dividing circuit 1a which inputs the input signal f 1  and the output signal f a  of the frequency dividing circuit 1b which inputs the output of the inverter circuit 2 for the input signal f 1  is generated to generate the signal f 2  similar to the frequency of the original input signal f 1 . The signal delay propagation of the exclusive OR circuit is smaller than that of an FF circuit, so this regenerated signal f 2  is used instead of the original input signal f 1 . Consequently, the skew between the original frequency signal and 1/2 frequency signal is reduced.

Title: Out-of-focus detector
Inventor: ANDOU HIDEO
IPC: G11B7/09
Filed: 1983-08-31
Abstract: PURPOSE:To ensure stable out-of-focus corrections over a wide range by using a projection lens and a cylindrical lens set on the optical path of the reflected light fetched by an objective lens and a photodetector which detects the light passed through both projection and cylindrical lenses and having a specific relative position among these lenses. CONSTITUTION:An objective lens 6, a projection lens 10 and a cylindrical lens 11 are set to satisfy (L-f0)+(f1H/f1-H)<=f0<2>/2delta'00. In this case, f0 is the focal distance of the lens 6, f1 is the focal distance of the lens, L is the length of the optical path between lenses 6 and 10, and H is the length of the optical path between lenses 10 and 11, respectively. It is supposed that the allowance degree of an out-of-focus state is about 5mum at most. Thus delta00 must be set at least at >=5.0mum and therefore delta'00-0.005mm. is satisfied to set each element. In such a way, an out-of-focus detection signal can be obtained with high stability over a wide range centering on the position of a focused point since the place where the out-of-focus detection characteristics are converted is distant away from said focused point.

IPC: G01B5/02
Filed: 1982-09-16
Abstract: PURPOSE:To discriminate whether dimensions of an electric parts lead are uniform or not, before fitting it, by constituting so that one end whose distance to a supporting point of a detecting rod is shorter is depressed by the lower end of a lead of electric parts, and dimensions of the lead are inspected by displacement of the other end whose distance is longer. CONSTITUTION:When electric parts 1 are placed on a supporting base 1, and are fixed by a holding rod 6, a detecting part 5 of a parts lead 2 depresses one end of a detecting rod 7. If it is assumed that the time when the detecting rod 7 becomes horizontal shows standard dimensions of the parts lead, a slight displacement of the detecting part 5 is amplified and indicated by a needle 10 of the other end through a supporting point 8. This amplification amount is determined by a ratio of length from the detecting part 5 to the supporting point 8 and length from the supporting point 8 to the needle 10. The displacement of the needle 10 can also be read by graduations marked on a frame 9 which is set suitably on a base 11. In this regard, the frame 9 is provided in accordance with each detecting rod 7, that which guides a movement of the detecting rod 7 will do.
