Abstract: An infinitely variable multi-directional linear motion solenoid actuator (10) for use on printed circuit boards (12). The solenoid actuator includes wire coils (14) wound onto a bobbin (16) and a moveable magnetic armature (18) passing through a central bore (20) of the body. The armature is responsive to current passing through the coils to produce infinitely variable and reversible motion. Support posts (22) passing through the bobbin are used for electrical connection between the coils and the circuit board, as well as for mounting the actuator to the circuit board. The support posts may have solder heads on one end for surface mounting to the board, and may have plain heads on an opposed end for alternative through-hole mounting. A vacuum pick area (56) may be formed on one or both sides of the bobbin body to facilitate automated handling of the actuator.

Abstract: An actuator and integral position sensor has increased reliability with a fail-safe mode. The actuator and sensor assembly includes a rotary actuator that has a driving shaft. A sensor rotor has the driving shaft mounted in a bore. A contactor is mounted to an outer edge of the rotor. The contactor is engaged with a resistor film as the rotor rotates. A driven shaft is mounted to the rotor in another bore. The rotor couples the driving shaft and the driven shaft together.

Abstract: A variable resistor includes a reduction rotation transmission mechanism including a plurality of gears for transmitting rotation of an operating member, a resistance member including a rotary member for varying resistance, and a rotation transmission member for rotating the rotary member. A plate-shaped clutch is disposed between the rotation transmission member and a geared wheel disposed at a termination end of the reduction rotation transmission mechanism, so that a clutch mechanism is formed. The transmission of the rotation of the rotation transmission member is performed and the rotation of the rotation transmission member is stopped by the clutch mechanism.

Abstract: In a motor-driven slide type variable resistor, the tensioning of a toothed loop belt joined to an operating lever is adjusted with a pin adjusted to change the distance between a toothed pulley and a follower pulley in order to adjust a traveling speed of the operating lever.

Abstract: An angular position sensor determines the angular orientation of a rotatable shaft. The device includes a rotor rotatable with the shaft. A first housing receives the rotor and a second housing at least partially surrounds the first housing. A flexible member between the first housing and the second housing permits vibration of the first housing while the second housing remains stationary.

Abstract: An electromotive adjustable resistor, comprising an electric motor which includes a motor shaft and a gear train which has two worm gear engagements and a cylindrical gear engagement. The cylindrical gear engagement provides a distance (space) between the resistance adjusting shaft and the motor shaft along the axis of both shafts. Accordingly, the axes of the two shafts can coincide or nearly coincide without interfering with each other. This narrows the width of the electromotive adjustable resistor, and minimizes the space on the circuit board occupied by the adjustable resistor.

Abstract: A signal level adjuster has a first variable resistor and a second variable resistor. The first variable resistor is inserted in a signal line, and the resistance thereof is variable by a motor. The second resistor is mechanically interlinked to a control knob on a control panel so that the resistance of the second resistor can be varied by the control knob. The motor is energized depending on a change in the resistance of the second variable resistor. The first level adjusting variable resistor may be positioned at any desired location so that and the signal transmission line is shortened.

Abstract: An electromechanical transducer comprises first and second links pivotally connected to a base, an electrical resistance element in the form of a track mounted on the base and a wiper arm mounted at one end of the second link and slidingly engaging the track. The first link and the second link are so coupled that pivoting one link is operative to pivot the other link and the angle through which the second link pivots is substantially greater than the angle through which the first link pivots. By suitable selection of the shape and/or the resistance profile of the track, the angular movement of the first link may be arranged to be a particular linear or non-linear function of the resistance tapped by the wiper arm. A control unit incorporating the transducer is also described.

Abstract: A cam program controlled system providing a continuous set point signal representing a time function relationship using an impulse or stepping drive motor. The drive motor impulses are electronically derived; and therefore, the system's time base or speed can be readily varied using switches and/or jumpers, instead of requiring gear train or motor changes. Also, the drive motor is coupled to the cam program through only a pinion and an anti-backlash drive gear. The cam follower arm is biased against the cam with a constant force. Controls are provided so that a cam scriber built into the cam follower and a controller which is normally provided in the system enables the system to be used for preparing new cams.
