Abstract: A driving support apparatus which performs driving support regarding a traffic signal includes: a communication device which acquires time-series traffic signal information regarding the lighting state of the traffic signal; a time calculating unit which calculates the time remaining until the lighting state changes on the basis of the traffic signal information; and an output device which notifies a driver of lighting time information regarding the time remaining. When the time remaining is equal to or smaller than a threshold value, the output device does not perform notification of the lighting time information so that it can be difficult for the driver to predict the timing at which a red lighting state of the traffic signal will change. Accordingly, it becomes possible to suppress unsafe action by the driver based on the traffic signal information notification received.

Abstract: Provided is an angular velocity sensor including a first vibration element, a second vibration element, and a support substrate. The first vibration element detects a first angular velocity about an axis parallel to a first direction. The second vibration element detects a second angular velocity about an axis parallel to a second direction obliquely intersecting with the first direction, and generates an output signal corresponding to a third angular velocity about an axis parallel to a third direction orthogonal to the first direction. The support substrate supports the first vibration element and the second vibration element.

Abstract: The present invention intends to solve the above described problems and provides a high reliability complex type thin film magnetic head in which high recording magnetic field density is achieved without deteriorating an MR element by heat, and in the case when the complex type thin film magnetic head is of sliding type, eccentric friction likely to occur in a lower magnetic core and a upper magnetic core is relaxed and production method thereof. The complex type thin film magnetic head is structured by forming an MR head portion on an inductive head portion produced on a base substrate. Conductive coils are formed on the recess portions formed on the lower magnetic core because the groove portions exist through a first flattening layer.
