IPC: H04N5/232
Filed: 1988-02-17
Abstract: PURPOSE:To attain an image pickup even when an object luminance is low at night by selecting for an autofocus either of a measurement means or a peak value detection means in accordance with a object condition. CONSTITUTION:A control circuit 10 obtains the extension position of an image pickup lens 1 through measurement information from a measurement circuit 12 and the present position information of the image pickup lens 1 from a lens position detection circuit 6 and drives the image pickup lens 1. On the other hand, a video signal which is photoelectric-converted in a CCD 3 and obtained is fetched into an AF signal processing circuit 9 and the detection of the peak value of the signal of a high frequency component is executed. When a peak detection failure signal from the AF signal processing circuit 9 is outputted or when a signal calling an attention to use a stroboscope is outputted from a photometry circuit 11, the control circuit 10 executes a driving control (AF control) from the beginning to the end of the image pickup lens 1 based on a signal from the measurement circuit 12.

IPC: G01M13/00
Filed: 1994-02-04
Abstract: PURPOSE:To inspect the thread accuracy of a nut automatically and accurately by moving an acceptable nut screwed down in the direction of the base end of a gauge while a failed nut is released from the engagement by reversing the gauge. CONSTITUTION:Nuts 1 fed into a hopper 51 are arranged with an intermittent feeder 56 vertically in a vertical groove of a guide frame 53 and the nut 1 at the lowest end of the frame 53 is sent with a guide rod 58 into a fitting groove 46 of a nut holder 4. The nuts 1 abuts a gauge part 21 at the tip of a gauge 2 turned normally and when the accuracy of an acceptable product, namely, a female screw is good, it is screwed down on the gauge part 21. Then, the nut is sent to other nuts 1 to be screwed down sequentially and drops at releasing parts 22 and 32 to collect. In the case of a rejected nut, it is screwed down partially on the gauge part 21 while being mated therewith to block the rotation of the gauge 2. As a results, the torque of a motor rises exceeding a set value and a controller rotates the gauge 2 reversely based on an electrical signal thereof to release the engagement thereof. At the same time, the holder 4 is moved so that the groove 48 reaches the position of the tip of the gauge 2 to collect being separated downward through openings 45 and 61.

Abstract: PURPOSE:To increase the adhesion between a bonding pad and a bump, or a gold ball in a wire bonding, by make the area of the metal wiring layer of the lower layer smaller than that of the metal wiring layer of the uppermost layer constituting the bonding pad thereby forming a step in the pad. CONSTITUTION:A first metal wiring layer 10 is made shorter than a second metal wiring layer 12 toward the inside of the semiconductor device. By this, a step is formed in a pad opening 13. Further, to prevent the first metal wiring layer 10 and an insulation film 5 of the second metal wiring layer from being destroyed when a probe card is brought in contact with them, the first metal wiring layer 10 and the second metal wiring layer 12 are connected using a hole 11. Consequently, the surface area with which the gold ball in a wire bonding or the bump contacts increases as much as the step, and thus it can be effectively large. In addition, the stylus of the probe card does not slide, and a sufficient stylus pressure can be applied to prevent poor contact.
