Title: Abnormal gear detecting method
Inventor: TSUJI MASANOBU
IPC: G01H17/00
Filed: 1989-05-29
Abstract: PURPOSE:To detect abnormalities which are overlooked in judgment only for absolute values by comparing the magnitude of the component of the intermeshing frequency of gears with a specified level, and judging the abnormality of a gear system when the magnitude exceeds the level. CONSTITUTION:Check is started at an intermeshing frequency fgm. The attenuation trend in the separating direction from the frequency fgm is checked with respect to each frequency of f=fgm-K.fm (K=1, 2, - Z). Then, whether the level of the absolute value of the frequency fgm exceeds a reference value or not is checked. When the reference value is exceeded, where the abnormality occurs in the gear system wherein gears are intermeshed is judged. At the same time, the attenuating trend of the component of every frequency which is the divided part for every fm is checked. When the values are attenuated continuously, it is judged that the gear is normal even if the level of the component of the frequency is high. When the attenuation is stopped in the halfway and the constant level continues, it is judged that the gear is defective.

Filed: 1989-05-29
Abstract: PURPOSE:To economically minimize power consumption and reduce cost by providing a locking part capable of holding an armature in a locking position in the middle of its stroke, and providing a locking member for making a locking body free. CONSTITUTION:A locking member 28 is protruded on the inner wall surface of a guide cylinder 26. The locking member 28 is formed of a first member 30 and a second member 32.

Title: Detecting device for mobile body
Inventor: SUZUKI MASAHITO
IPC: H04N7/18
Filed: 1986-06-13
Abstract: PURPOSE:To detect a mobile body without missing it even on an oblique passing or a lateral movement within a monitor area by updating and storing the position of the mobile body even when the position of the mobile body in the monitor area is gradually changed. CONSTITUTION:A passing coordinate such as the blurring of a head or a slight change in a route at the time of walking when a human being passes a fixed position (coordinate K1, K2) in the monitor area 20 is changed gradually. Therefore, as shown in the example of the oblique passing in the figure, if the deviation width  k1 between the coordinate K of the time t1 and the coordinate K' of the time t2 is situated within an allowable range, the contents of a mode memory 5 are updated and the content of a pattern memory 6 is moved to the coordinate K' as it is. In such case, the respective contents of the coordinate K are cleared. Similarly, the deviation width  k2 between a coordinate k'' at the time t3 and K' is obtained, if it is situated within the allowable range, the contents are moved to the coordinate K''. The lateral movement in the monitor area can be processed according to a similar method.

IPC: H01H50/16
Filed: 1994-06-17
Abstract: PURPOSE:To provide a polar relay assembled well with which stable bistable operation can be carried out with good magnetic efficiency. CONSTITUTION:A coil frame 3 provided with a both-end wall 3a and an intermediate wall 3b is integrated into a U-shaped yoke 1. A through hole 3d is provided on the intermediate wall 3b of the coil frame 3. A permanent magnet 2 is inserted into the through hole 3d from the one magnetic electrode side. The magnetic electrode surface of the inserted side of the permanent magnet 2 is abutted on the center of the yoke 1, on which the permanent magnet 2 is mounted by the magnetic force of the permanent magnet 2 itself. Since welding or adhesive agent is not needed in order to mount the permanent magnet 2 on the yoke 1, the magnetic resistance is not increased, and a polar relay of good magnetic efficiency can be achieved. Since the permanent magnet 2 can only be inserted into the through hole 3d of the intermediate wall 3b, assembly work is facilitated, and the manufacturing cost can be reduced.

Filed: 1987-05-30
Abstract: PURPOSE:To drive plural instruments by a single constant current circuit by supplying a driving current to the constant current circuit at a specific limited time once an input signal is received, and controlling the constant current circuit so that driving currents of respective instruments do not overlap with one another in terms of time. CONSTITUTION:When there is an input IN1 from an object of measurement to a CPU, an output OUT1 is '1' and a driving current flows to an instrument m1 unless a time limit circuit is ON. If, however, there is an input IN2 while the driving current flows to the instrument m1, the input IN2 is stored and held since the time limit circuit is ON, and the an output OUT2 is varied to '1' when the output OUT1 is ceased, namely, varied to '0' to supply a driving current to an instrument m2. Therefore, the single constant current circuit operates the two instruments in response to the two inputs.
