COOKING APPLIANCE USER CONTROL INTEGRATED WITH RATE OF MOVEMENT DETECTION
A cooking appliance may use a sensor to sense a rate of movement of a user control and generate an alert when the rate of movement meets an alert criterion, thereby enabling detection of potential inadvertent movements of a user control.
ABSOLUTE ENCODER
An absolute encoder suitable for size reduction is provided.
The absolute encoder includes a spindle gear (1A) fixed to a motor shaft (201), a permanent magnet (9) provided on the spindle gear (1A), and a first driven gear having a center axis perpendicular to a center axis of a worm gear portion (181), and engaging the wo m gear portion (181). The absolute encoder includes a second driving gear provided coaxially with the first driven gear and rotating according to a rotation of the first driven gear, and a second driven gear having a center axis perpendicular to the center axis of the first driven gear, and engaging the second driven gear. The spindle gear (1A) includes a magnet holder (170) which is fit onto a tip end of the motor shaft (201), coaxially with the motor shaft (201), and a resin gear portion (180) provided with the worm gear portion (181) on an outer side in a radial direction.
ABSOLUTE ENCODER
An absolute encoder preferable in being made compact is provided.
The absolute encoder includes a worm gear (101c) that rotates in accordance with rotation of a main spindle, and a worm wheel (102a) of which a central axis is perpendicular to a central axis of the worm gear (101c), the worm wheel engaging with the worm gear (101c). The worm gear (101c) is formed using a first material, and the worm wheel (102a) is formed using a second material different from the first material.
REDUCTION MECHANISM AND ABSOLUTE ENCODER
An absolute encoder preferable in being made compact is provided.
The absolute encoder includes a first drive gear, a first permanent magnet, a first angle sensor, and a first driven gear of a central axis that is perpendicular to a central axis of the first drive gear, the first driven gear engaging with the first drive gear. The absolute encoder includes a second drive gear coaxially provided with the first driven gear, the second drive gear being configured to rotate in accordance with rotation of the first driven gear. The absolute encoder includes a second driven gear of which a central axis is perpendicular to the central axis of the first driven gear, the second driven gear engaging with the second drive gear. The absolute encoder includes a second permanent magnet provided on a top end side of the second driven gear. The absolute encoder includes a second angle sensor configured to detect a rotation angle of the second driven gear, in accordance with a change in magnetic flux generated from the second permanent magnet. A reduction ratio between the first drive gear (worm gear (101c)) and the first driven gear (worm wheel (102a)) is set to a value for mitigating an effect of backlash between the first drive gear and the first driven gear, the backlash resulting in an error in the rotation angle of the second driven gear.
COMBINATION TOOL FOR TENSIONED FASTENERS
An apparatus for tensioning a fastener while measuring displacement of the fastener relative to a female threaded member may include a driver extension having an interior channel aligned along the extension's central cylindrical axis, open to a socket driver at an output end of the driver. The apparatus may further include a measurement probe in the interior channel, coupled to a measurement indicator on an exterior of the extension by a coupling that moves the measurement indicator in proportion to movement of the measurement probe and a measurement gauge coupled to an exterior of the driver extension that gauges displacement of the measurement indicator. A method for using the apparatus includes driving a female threaded member along a threaded rod by the driver extension while holding the measurement probe against an end of a bolt, screw, or other threaded fastener of which the threaded rod forms a part and while reading the measurement gauge.

Method for correcting values detected by linear scales
Provided is a method for more accurately correcting position coordinates of a point on an object to be imaged, the coordinates being identified based on values detected by linear scales. A visual field is moved to a measurement point defined on a recessed portion formed on a calibration plate, and an image is captured (step S13-1), edges are detected from an image of sides of the recessed portion (step 313-2), an intersection of the edges is calculated (step S13-3), values of the intersection as actually measured by the linear scales are saved (step S13-4), and position coordinates of the point on the object to be imaged as detected by the linear scales are corrected by using a true value and a difference.

Combined plug-sensor wheel for a camshaft
A combined plug-sensor wheel for a camshaft is disclosed. The combined plug-sensor wheel includes a pin projecting in an axial direction of the camshaft. The pin, when inserted into the camshaft, seals the camshaft in a fluid-tight manner. According to an implementation, the combined plug-sensor wheel and the camshaft are incorporated into an internal combustion engine.
Cable Measurement System and Cutter Apparatus
A cable measurement system and cutter apparatus has a housing, a display device, a material conduit, a rotary encoder, a cutting tool handle a resistance member a movable cutting blade and a blade aperture. The cutter system is able to measure the length of a cable that passes through the material conduit which traverses through the housing. The display device is mounted onto the housing and is coupled to the rotary encoder which measures the length of cable passed through the housing. The encoder is mounted next to the conduit so that the cable is measured, and the length is displayed on the display device. one end of the cutting tool handle is rotatably mounted to the housing and the movable blade is mounted onto the opposite end of the handle. The blade is able to cut the cable by moving through the blade aperture which traverses through the conduit.
