  • Publication number: 20200292414
    Abstract: The present disclosure relates to an inspection apparatus and an inspection method, and a program that enable inspection of the performance of an image pickup element. Generation of collimated light and transmission of part of the collimated light through a transmission filter having a light-blocking face provided with circular holes arranged regularly, causes conversion to rays of columnar collimated light arranged regularly. An image including the rays of columnar collimated light arranged regularly, is captured by an image pickup element being inspected. Then, acquisition of the difference between the image captured by the image pickup element being inspected and an ideal image captured by an ideal image pickup element and comparison between the difference and a threshold, result in inspection of the performance of the image pickup element being inspected The present disclosure can be applied to the manufacturing of an image pickup device.

  • Publication number: 20200191571
    Abstract: A vibration gyroscope includes: a mass part supported to be displaceable in a first direction and a second direction; an exciter vibrating the mass part in the first direction; and a detector detecting a displacement amount of the mass part in the second direction. The first direction and the second direction are orthogonal to each other. A resonance frequency of the mass part in the first direction coincides with a resonance frequency of the mass part in the second direction. A Q-factor of vibration of the mass part in the second direction is smaller than a Q-factor of vibration of the mass part in the first direction.

  • Patent number: 5877959
    Abstract: An NC system capable of operating without a delay even if it uses a personal computer of low real-time processing performance. The NC system includes a general-purpose personal computer having a main bus and a plurality of expansion slots on the main bus. An NC board is installed in one of the expansion slots to control a servomotor and so forth. A PLC board is installed in another of the expansion slots to effect sequence control and so forth. The NC board and the PLC board are interconnected by a subbus other than the main bus.

  • Patent number: 4058777
    Abstract: An oscillator circuit comprised of three bistable circuits connected in cascade, a circuit for generating first timing signals, and a circuit for generating second timing signals. Output signals from the series of bistable circuits are applied to enable the circuits for generating timing signals, and the timing signals are applied to an input of the series of bistable circuits to change the states of the bistable circuits. After a first time interval has elapsed the first timing signal changes the state of a first bistable circuit which in turn successively changes the states of the other bistable circuits. After a second time interval has elapsed after the changes of state effectuated by the first timing signal, the second timing signal changes the state of the first bistable circuit which in turn successively changes the states of the other bistable circuits, so that the bistable circuits repetitively change state with a period equal to the sum of the first and the second time intervals.
