A portable terminal apparatus is mounted in a casing and has a magnetic sensor that detects a magnetic field around the casing with an offset and outputs magnetic data representing the detected magnetic field, and a tilt sensor that detects a tilt of the casing and sequentially outputs tilt data representing the detected tilt. In the portable terminal apparatus, a capture part sequentially captures the magnetic data from the magnetic sensor at a given time interval. A calculation part calculates the offset of the magnetic sensor based on a plurality of the magnetic data sequentially captured by the capture part. A detection part detects an orientation variation of the casing based on the tilt data sequentially outputted from the tilt sensor. A change part changes the time interval for sequentially capturing the magnetic data in accordance with the detected orientation variation.

A method is designed for measuring a magnetic offset of a geomagnetic sensor equipped in a portable information terminal apparatus having a storage. The geomagnetic sensor has a magnetic sensitivity to a geomagnetic field and is affected by magnetization to cause the magnetic offset. In the method, an output of the geomagnetic sensor is measured to successively provide measurement data of the geomagnetic field from the output of the geomagnetic sensor. The measurement data is stored in the storage. The measurement data is read out from the storage when a number of the measurement data stored in the storage reaches a predetermined number, and an offset value of the magnetic offset is estimated based on the predetermined number of the measurement data read out from the storage.

On a single chip are formed a plurality of magnetoresistance effect elements provided with pinned layers having fixed magnetization axes in the directions that cross each other. On a substrate 10 are formed magnetic layers that will become two magnetic tunnel effect elements 11, 21 as magnetoresistance effect elements. Magnetic-field-applying magnetic layers made of NiCo are formed to sandwich the magnetic layers in plan view. A magnetic field is applied to the magnetic-field-applying magnetic layers. The magnetic field is removed after the magnetic-field-applying magnetic layers are magnetized in the direction shown by arrow A. As a result of this, by the residual magnetization of the magnetic-field-applying magnetic layers, magnetic fields in the directions shown by arrows B are applied to the magnetic layers that will become magnetic tunnel effect elements 11, 21, whereby the magnetization of the pinned layers of the magnetic layers that will become magnetic tunnel effect elements 11, 21 is pinned in the directions shown by arrows B.

A magnetic sensor 10 includes GMR elements 11-18, and heating coils 21-24 serving as heat generating elements. The elements 11-14 and 15-18 are bridge-interconnected to constitute X-axis and Y-axis sensors, respectively. The heating coils 21, 22, 23, and 24 are disposed adjacent to the elements 11 and 12, the elements 13 and 14, the elements 15 and 16, and the elements 17 and 18, respectively. The heating coils 21-24, when electrically energized, heat mainly the adjacent elements. Therefore, the elements can be heated and cooled in a short period of time in which constant geomagnetism can be ensured. Data for compensation of temperature-dependent characteristic (ratio of change in sensor output value to variation in element temperature) is obtained on the basis of the temperatures of the elements before and after the heating, and the magnetic sensor outputs before and after the heating. Subsequently, the temperature characteristics of the elements are compensated on the basis of the data.

A content display-playback system includes a content providing apparatus, a content display-playback apparatus, and an operation control apparatus for controlling the apparatuses. On the basis of operation control by the control apparatus, content is transmitted from the providing apparatus to the display-playback apparatus for display and playback through a network. The control apparatus includes an input operation receiving unit for receiving an operation input, a control signal generating unit for generating a control signal for transmitting and receiving the content among the providing, display-playback, and control apparatuses in response to the operation input, and a storage unit for storing selection-history information. When the receiving unit receives an operation input for transmitting the content from the providing apparatus to the display-playback apparatus, the generating unit generates a control signal for selecting a display-playback apparatus on the basis of the selection-history information and transmitting the content to the selected display-playback apparatus.
摘要:
A production device and a method produce a multicomponent film containing metal components such as TiAlN having greatly different melting points by a melting-evaporation type ion plating method which has high material use efficiency and provides a good film quality. For this end, electric power required to evaporate material (4) is first supplied and then electric power stepwise increased from the first electric power is repeatedly supplied until a required maximum electric power is reached. At the same time, plasma control is performed for converging plasma (7) into an initial area required to evaporate the material and then plasma control is performed for successively and stepwise moving and expanding the plasma from the initial plasma area up to a maximum plasma area to gradually melt a non-melted portion of the material.
