Title: Acceleration sensor
Inventor: KATO TOMIO
IPC: G01P15/18
Filed: 1995-10-03
Abstract: PROBLEM TO BE SOLVED: To provide a function to put a mobile member back automatically to a reference axis accurately when it returns to a stationary state from a non-stationary state by providing an auxiliary permanent magnet having a magnetic pole with the direction thereof the same as that of a permanent magnet on a magnetic detector in a non-magnetic container and the reference axis. SOLUTION: In the stationary state where no acceleration of vibration, impact or the like is applied to a sensor 1, a mobile member 5 is positioned on a reference axis 10 as a convex spherical surface of the member 5 comes into contact with the bottom surface of a container by the attraction of an auxiliary permanent magnet 7 and a permanent magnet 4. At this point, a magnetic pole of the magnet 4 supplies a sufficient magnetic flux to a Hall IC of a magnetic detector 3. When a horizontal acceleration is applied to the sensor 1 in the non-stationary state, the mobile member moves from the reference axis 10 and output of the Hall IC is turned off, so that an output voltage goes to a high level.  When the acceleration vanishes again to come back to the stationary state, the member 5 rolls on the bottom surface of the container by the attraction of the magnet 7 and the magnet 4 to return onto the reference axis 10 again. The Hall IC supplies a sufficient magnetic flux to turn an output transistor on and a voltage of a low level L is outputted.

Abstract: PURPOSE:To perform the adjustment and inspection of focus detection irrelevantly to a photographic sequence by operating selectively a control part which performs the focus detection according to the photographic sequence and a control part which performs the focus detection irrelevantly. CONSTITUTION:It is decided which of an input and an output mode a terminal P7 of CPUMC2 is set in and when the terminal is in input mode, it is a single mode, so an advance to a prescribed number is made; when the terminal is in output mode, an advance to another prescribed number is made. This switching step is added and then an AF microcomputer MC2 operates independently irrelevantly to a control part MC1 only by inputting a start signal for AF operation, so that an automatic focus adjustment part makes an operation check and adjustment alone. When a terminal P12 is at H and the terminal P7 is in output mode, a calculated defocusing quantity DELTAepsilon is only outputted for check adjustments, thereby facilitating checks and adjustments.
