摘要:
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.

摘要:
A magnetic sensor is constituted using magnetic sensor chips mounted on stages supported by interconnecting members and a frame having leads in a lead frame. Herein, the stages are inclined upon plastic deformation of the interconnecting members. When the frame is held in a metal mold and the stages are pressed, the interconnecting members are elastically deformed, so that the magnetic sensor chips are bonded onto the stages placed substantially in the same plane and are then wired with the leads. Thereafter, the stages are released from pressure, so that the interconnecting members are restored from the elastically deformed states thereof. When the magnetic sensor chips are combined together to realize three sensing directions, it is possible to accurately measure three-dimensional bearings of magnetism, and the magnetic sensor can be reduced in dimensions and manufactured with a reduced cost thereof.

摘要:
In an apparatus for sorting articles on hangers, a chain pushes articles along an elongated guide rail. The guide rail has a series of gaps, each of which is normally bridged by a pivoted sorting member. At an open gap, the articles are diverted to a horizontal transfer apparatus comprising a rotatable, disc-shaped, article-receiving member. The receiving member conveys articles to the upper end of a downwardly inclined sorting chute. A ridge-shaped, arcuate guide extends along a portion of the perimeter of each receiving member to prevent articles from falling off the receiving member. The horizontal transfer apparatus enable the chutes to be positioned laterally away from the guide rail so that they do not interfere with movement of hangers having horizontal shoulders.

Disclosed is an electronic apparatus wherein a large power consumption type semiconductor device is mounted on a ceramic substrate of sintered aluminum nitride with high thermal conductivity for improving a heat dissipation effect. The electronic apparatus is, for example, an ignitor. The aluminum nitride-made ceramic substrate having the semiconductor device is provided in a metallic vessel made of aluminum or the like. Employed is a thermal stress strain-resistant adhesive agent with high thermal conductivity such as a silicone type adhesive agent for bonding. The thermal stress strain-resistant adhesive agent layer serves as a cushioning layer for a heating and cooling cycle and therefore improves a heat cycle resistance.
