Scanning apparatus

Disclosed is a vehicle antitheft device not requiring a contract with a security company, etc., and increasing a vehicle antitheft effect. In the vehicle there are provided a camera or a microphone, and a control device for distinguishing a face or voice of a human by means of an image or sound captured by the camera or microphone, and based on distinction results, executing vehicle theft prevention control operations. The camera is provided at a position capable of capturing a normally seated driver and the outside through a window next to a driver's seat. Further, in the vehicle there is provided a radio communications unit. The control device records the captured image from the camera, judges whether the it is the face image of the person, and if it is, performs control so that the image is sent to a given reporting destination via the radio communications unit.

A torque sensing unit, sensor unit, and method for manufacturing the torque sensing unit. The torque sensing unit includes a first shaft and a second shaft rotatably arranged in a coaxial fashion, and a torsion bar for allowing a rotational displacement in response to a torque between the first shaft and the second shaft. Magnetic elements are used in conjunction with the shafts for sensing a reluctance which is changed in compliance with rotational phase differences between the magnetic elements. A sensor module is prepared in which the magnetic elements are temporarily fixed to have a predetermined neutral rotational phase difference. This temporary fixture is released after the first shaft , the second shaft , the torsion bar , and the sensor module have been assembled.

A cage,comprising rings,and a plurality of elastic rods,are secured to facing ends,of an upper shaft,and a lower shaft,, and movable elements,are secured to and span two of the elastic rods,. Wings,on the movable elements,are displaced radially by a large amount in response to a slight twisting of the elastic rods,. This radial displacement is detected by a detection means, such as coils,, which generates a magnetic flux in a magnetic circuit which includes the wings,and detects the displacement as electromagnetic change. The tips of the wings,extend axially along the elastic rods and the wings,are displaced radially in accordance with changes in the attitude of body portions,in response to changes in torque. Two wings,and two detection means,are disposed facing each other for each body portion

A torque detector is provided with movable magnetic elements each comprising: an element body, which deforms elastically in response to relative shear displacement between the surfaces of an upper shaft and a lower shaft; and soft ferromagnetic wings, which are supported by the element body and change their inclination relative to the axial direction due to the elastic deformation of the element body, the inclination of the wings being detected by coils.
