Abstract: A connector has a first contact and first signal contacts, and a second contact and second signal contacts arrayed at a different height. All the contacts have connection portions arranged at the same height position. The connection portion of the first contact is located between the connection portions of the second signal contacts and the connection portion of the second contact is located between the connection portions of the first signal contacts. A distance B is larger than a distance A. The distance A is a distance between the connection portion of the first signal contact and the connection portion of the second contact and also a distance between the connection portion of the second signal contact and the connection portion of the first contact. The distance B is a distance between the connecting portion of the first signal contact and an adjacent connection portion of the second signal contact.

Abstract: A connector with a structure having a tip of a body holding a first contact set is located in an opening formed by a shell member including a shell and a shield cover. A tip of a body holding a second contact set is located in an opening formed by the shell member, and a plurality of receptacles are integrated, a shield plate is placed between the first contact set and the second contact set in parallel with a direction orthogonal to the longitudinal direction of contacts in the two contact sets to reduce crosstalk between the plurality of receptacles.

Abstract: A navigation apparatus performs operations for detecting and indicating at least the driving direction of a moving vehicle. The apparatus comprises an angular velocity sensor for detecting an angular velocity according to a change in driving direction of the moving vehicle and outputting angular velocity data; a direction sensor for outputting direction data corresponding to a change in the driving direction of the moving vehicle. The apparatus further includes straight-movement offset reset means for detecting a straight travelling status of the moving vehicle from at least the angular velocity data and direction data, and for, when the moving vehicle is moving straight, setting a reference value of the output of the angular velocity sensor as an output value for that time.

Abstract: When the body of an automobile equipped with a stand-alone navigation system is magnetized by an external magnetism, an unknown magnetization vector is determined by correcting the known magnetization vector. Even very small changes in the magnetization vector can be corrected without putting a burden on the user of the automobile. A magnetization vector directed from a reference position toward the center of a magnetic circle which indicates the magnetized condition of the automobile body is detected, and a geomagnetic vector which is directed from the reference position in the direction in which the mobile body progresses is detected. An instantaneous direction vector which is directed from the center of the magnetic circle in the direction in which the mobile body progresses and which has a direction angle is calculated.

Abstract: The navigation device includes vehicle condition discriminating unit for discriminating whether the vehicle is stopped or not, angular velocity detecting unit for detecting change of direction of the vehicle and producing angular velocity data on the basis of the detected change of direction, absolute direction detecting unit for detecting geomagnetism and producing absolute direction data on the basis of the detected geomagnetism, offset processing unit for producing corrected angular velocity data from the angular velocity data and a first reference value, and offset reset unit for renewing the first reference value. The offset reset unit renews the first reference value with the angular velocity data which is obtained when the vehicle is discriminated to be stopped, a change rate of the angular velocity data is within a predetermined second reference value and a change rate of the absolute direction data is within a predetermined third reference value.

Abstract: A global positioning system for positioning a mobile object such as an automobile in a global geometrical region includes a GPS receiver for receiving radio waves from a plurality of satellites and outputting either two-dimensional position data indicative of the present position of the mobile object in a two-dimensional position measurement mode or three-dimensional position data indicative of the present position of the mobile object in a three-dimensional position measurement mode. An altimeter detects a relative altitude of the mobile object and outputs relative altitude data indicative of the detected relative altitude. A present position output unit calculates present position data indicative of the present position of the mobile object solely based on the data from the GPS receiver while the GPS receiver is operating in the three-dimensional position measurement mode.

Abstract: A synchronizing signal extraction circuit for digital magnetic tape decks, in which a level of a synchronizing signal is differentiated and compared against a minimum level. The synchronizing signal is used for reproduction purposes only if the differentiated synchronizing signal exceeds the minimum level. Thereby, old incompletely erased synchronizing signals are masked.

Abstract: In a digital audio recording/reproducing apparatus of the rotary head type, erasure of signals in previously recorded tracks, which are used to control the operation of a tracking servomotor, is enhanced by the provision of a magnetic field generator prior to the point where overwriting occurs. As a result, errors in the tracking error signal arising due to unerased remnants of the previously recorded signals are eliminated.
