摘要： PROBLEM TO BE SOLVED: To provide a moving object detecting device capable of detecting an object only slightly moving. SOLUTION: In a two-dimensional orthogonal coordinate system, when a vector Rn, of which an original point is a start point and Xn,Yn, which are values of a pair of Doppler signals E,E' at an amplitude level, is an end point, rotates in accordance with passage time, the rotating angles ψn are obtained to be integrated. Furthermore, the integrated value of the rotating angles ψn is compared with a predetermined threshold by a threshold circuit 88, and when the integrated value exceeds the threshold, a detecting signal is transmitted. Involving information which is omitted in previous examples when a pair of Doppler signals E, E' are binarized, the variation in Doppler signals E, E' can be investigated in detail, so that it is possible to detect an object only slightly moving, which can not be detected in conventional examples, for example, an object O moving at the level of staying in the same quadrant.

摘要： PROBLEM TO BE SOLVED: To always obtain an detected output having a preset or more pulse width independently of the speed of a game ball and prevent detecting errors due to chattering. SOLUTION: When output voltage Vo is changed from an L level to an H level after a game ball is detected once, a detection circuit 2 is controlled to fix output voltage Vm at the level (H level), at which the game ball is detected, until the counting of a timer Tm in a timer circuit 7 is finished. Even if the game ball passes through a hole during counting the timer or chattering occurs, the output voltage Vo is fixed at the level (H level) at which the game ball is detected. As a result, an output signal Vo having a pulse width, not shorter than that of the timer Tm, is always obtained independently of the passing speed of the game ball or the presence of chattering.

摘要： PROBLEM TO BE SOLVED: To ensure sufficient function of a sensor circuit while protecting against reverse connection by constituting a current direction limiting means of a transistor where a driving current flows between the collector and the emitter, and a resistor for passing the base current of the transistor. SOLUTION: The current direction limiting resistor RR of a sensor circuit 10 constitutes means 20 for limiting the direction of a driving current supply together with a transistor Tr and a collector current for driving the sensor circuit 10 flows when a base current flows into the transistor Tr. Direction of a current flowing into a first operational amplifier Amp 1 is limited to the direction of collector current of the transistor Tr. Consequently, the sensor circuit can function sufficiently by varying the resistance of a resistor in the current direction limiting means appropriately along with the transistor while being protected against reverse connection.

摘要： PROBLEM TO BE SOLVED: To reduce the leakage of high frequency signals between terminal plates of movable terminal blocks so as to changeover the high frequency signal by arranging a grounding terminal plate between the terminal plates of the adjacent movable terminal blocks, which are arranged in parallel with each other, in parallel with the plates of the movable terminal blocks. SOLUTION: In common terminal plates 23, 23, which are commonly used for relay groups arranged in the same sequence direction, each armature parts 11 is held with the predetermined space so as to correspond to a relay in the sequence direction. A movable terminal block 100 is supported by supports through the common terminal plates 23, and arranged over an iron care. A space between adjacent movable terminal blocks 100 is widened a little, and a grounding terminal plate 110 is arranged between them in parallel with them. With this structure, generation of cross-talks due to leakage of high frequency signal from the common terminal plate 23 of the movable terminal block 100 to the common terminal plate 23 of the adjacent movable terminal block 100 is prevented by grounding through the grounding terminal plate 110.

摘要： PURPOSE:To individually separate and detect each metallic ball even when the metallic balls continuously pass through. CONSTITUTION:An oscillation circuit 2 is equipped with a LC resonance circuit 1 disposed close to the passing route of each metallic ball.. Current is fed to the oscillation circuit 2 through a constant current circuit 6, and an output circuit 3 is provided for the input side of the constant current circuit 6, where the output circuit increases/decreases passing current amperage in response to the change in the output level of the oscillation circuit 2. When each metallic ball comes close to the LC resonance circuit 1, the output level of the oscillation circuit 2 is lowered, and the passing current amperage is also decreased. Therefore, flowing current to connection terminals t, and t. is changed in response to the presence and absence of each metallic ball. Besides, the oscillation circuit 2 keeps oscillating regardless of the presence and absence of each metallic ball, the presence and absence of each metallic ball can thereby be judged with excellent repeatability based on the change in flowing current to the connection terminals t1 and t2.
