摘要: A discharging circuit for a power source device with a rectifier circuit used in an power source for driving a motor in which when the alternating current power source is turned off and the load is electrically separated, the voltage of a time constant selection circuit (22, 23) falls rapidly, the voltage across a diode (25) rises, a Schmitt circuit (24) is activated, the circuit consisted of a transistor (27) and a resistor (26) is conducted, and a smoothing capacitor (28) is discharged, and hence the heat generation at the resistor is decreased and the concern over unsafety due to delayed discharge of the capacitor is eliminated.

摘要: In a photoelectric converter-type pulse encoder comprising a light-entrance portion (13, 13'), a rotating slit plate (12) on which a lattice plate receiving light from the light-entrance portion (13, 13') is formed, a fixed slit plate (11) on which a lattice plate arranged to face the lattice plate of the rotating slit plate is formed, and a light-receiving portion (14, 14') arranged below the fixed slit plate, light is emitted from a light-emitting circuit to the light-entrance portion (13, 13') through the light fibers (17), and the light received by the light-receiving portion (14, 14') is introduced into a light-receiving circuit through the light fibers (17), thereby adjustment of the amount of light is made easier, the pulse generation in response to the rotating speed is ensured, and the rotating speed is detected with a high precision.

摘要: In a non-contacting, speed-detecting device of a DC generator type; comprising a cylindrical permanent magnet rotator 1 having N and S poles distributing alternatingly in the circumferential direction, a stator 2 facing said rotator 1 in which stator output windings 4 are wound, a permanent magnet 3 for location rotating coaxially with the rotator 1, and magnetic induction switches 5 positioned close to the circumference of the magnet 3; switching the flat portions of the multi-phase trapezoid AC signals generated in the output windings by switches 5 in response to the rotating position of the magnet 3 for location; and obtaining a DC voltage proportional to the speed; the S pole regions and the N pole regions of the magnet 3 for location are formed continuously so that the magnetic field is inverted steeply from one polarity to another polarity, and the ratio of the width of the S pole regions and the width of the N pole regions is selected to be a value other than one, whereby only the flat portions of the multi-phase trapezoid AC signals generated in output windings are switched exactly without being influenced by the variation of the operating level of the switches 5 and a rippleless DC voltage is obtained.
