Abstract: PURPOSE: To avoid a position detection error caused by noises, switch the current application to armature windings properly, reduce the vibration and noises and avoid a step out. CONSTITUTION: When a DC power supply Vdc is switched by an inverter unit 4 and is applied to the armature windings of a brushless motor 3, the inverter unit 4 is driven in accordance with the detection of the position of the rotor 3a of the brushless motor 3 to switch the current application to the armature windings. An induced voltage induced in the armature winding is compared by a comparator 5 with the half value of the reference voltage Vdc from a reference voltage generating circuit 5a and a position signal which is changed at the cross point of the comparison results is inputted to a controller 10 which counts the intervals between the changing points (position detection points) of position signals and calculates noise mask periods based upon the counted time intervals and the position detection is not performed during the noise mask periods.

Title: Step motor
Inventor: SATO KOICHI
IPC: H02K37/14
Filed: 1994-03-07
Abstract: PURPOSE:To prevent reverse rotation of rotor by shifting the center of gravity of one pole tooth in two-phase yoke by a distance shorter than a quarter of pole tooth pitch in the peripheral direction from that of the pole tooth in the yoke of the other phase closest in the forward rotational direction of the rotor. CONSTITUTION:When the coil of only phase B is disconnected, only phase A is excited and the -N pole 1a of a rotor is attracted to the -S pole of a pole tooth 13. Since the magnetizing force of the -N pole for phase B is shifted in the forward rotational direction, the -N pole is located at a slightly shifted position and both phases are brought into unexcited state. In this regard, the magnetizing forces of the pole teeth 13-16 of phases A, B and the rotor pole are balanced at a position shifted slightly to the left side. N and S poles appear, respectively, at the pole teeth 13 and 14 and the -N pole is shifted in the forward rotational direction by the repelling force of the N pole and the attracting force of the S pole. Consequently, the pole tooth 14 is converted from S to N pole and the the -N pole is rotated forward thus preventing reverse rotation of the rotor.

Title: Leakage current detector
Inventor: KUSUI SHOJI
IPC: G01R31/02
Filed: 1997-02-04
Abstract: PROBLEM TO BE SOLVED: To obtain effective leakage currents with high accuracy by multiplying a power line voltage signal by a zero-phase current transformer output signal, smoothing it to obtain its dc component signal, and comparing it with a dc signal proportional to a power line voltage at the time when a leakage current reaches a standard value. SOLUTION: The output current ig of a zero-phase current transformer ZCT is transformed to a voltage signal ei by an amplifier A. A multiplier M multiplies it by a voltage ev corresponding to a line voltage V to obtain an output signal em . The output signal em is smoothed by a smoother F to be a dc signal ef . An ac/dc converter B converts a voltage es corresponding to the line voltage V between power lines 1 and 2 to a dc signal Es via a transformer T. A comparator C compares the signal ef with the signal Es and outputs an actuating signal p at the time when both become equal to each other. Here, ef =KVIgcosϕ, Es =KsV (Ig: leakage current, K: constant, Ks: constant). The effective component of leakage currents becomes Igcosϕ=Ks/K for transmitting the actuating signal p at ef =Es , and it is possible to detect it regardless of the line voltage V.

Abstract: PURPOSE:To achieve higher detection accuracy of a water level meter and a flowmeter by setting a sound wave transducer at the upper end of a spiral sonic tube with an open lower end of the sonic tube positioned below a water level to be detected to expand a change in the actual water level apparently. CONSTITUTION:Water is injected into a container 11 from a water injection pipe 14 while flowing out at outflow ports 15a-15d so that water is retained in the container 11 by an amount equivalent to a difference between an injection quantity and an outflow quantity of the water. The water also flows into a spiral sonic tube 17 to the same height as that of water level. Under such a condition, when a sound wave transducer 13 is driven to emit a sound wave into a sonic tube 17 from a measuring device 21, the sound wave travels through the sonic tube 17 along the spiral thereof and is reflected on the surface 22 of the water therein to be returned to the sound wave transducer 13. The measuring device 21 computes the length of a path of the sound wave based on a delayed time to the arrival of the reflected wave from the time of the emission of the sound wave and furthermore, a flow rate is computed based on the depth H of the water at the outflow ports 15a-15d and opening areas of the outflow ports 15a-15d.
