    • To precisely and easily detect a disconnection failure in a bonding connection of a flip coil of a magnetic sensor, wiring patterns for connecting switching devices to a +FL terminal of an X-axis sensor and a +FL terminal of a Y-axis sensor are arranged on a circuit wiring board. After MOS transistors are mounted to the board, the wiring patterns are connected to each other by wiring in the MOS transistors. The MOS transistors are mounted to the circuit board so that a flip coil of the X-axis sensor and a flip coil of the Y-axis sensor are connected in parallel to each other. Before the MOS transistors are mounted on the circuit board, the resistance of each of the flip coils and is measured. The disconnection failure in bonding connection of the flip coils can be inspected based on the fact that a difference between a measured value in a case of good bonding connection and that in a case of bad bonding connection is large.

    • A steering gear for a motor vehicle includes a housing, a rack bar, a pinion, a support yoke, a spring, a split roller, and a plurality of bearings. The rack bar is slidably supported within the housing for transverse displacement therein along an axis. The rack bar has teeth on a first side. The pinion has teeth drivingly engaging the teeth of the rack bar. The pinion is rotatably supported within the housing. Rotation of the pinion transversely displaces the rack bar along the axis. The support yoke is slidably disposed in the housing for movement toward a side of the rack bar substantially opposite the teeth of the rack bar. The support yoke has an opening which is open toward the rack bar, with the opening defining two opposed bearing surfaces. The spring is disposed between the housing and the support yoke, and biases the support yoke toward the rack bar. The split roller includes a first split roller section and a second split roller section. The first split roller section is substantially conical in shape and has a large diameter side located proximate to one of the bearing surfaces. The first split roller section is rotatably disposed on and axially slidable toward the one of the bearing surfaces and tangentially engages the rack bar. The second split roller section is also substantially conical in shape with a large diameter side located proximate to an other of the bearing surfaces. The second split roller section is rotatably disposed on and axially slidable toward the other of the bearing surfaces and tangentially engages the rack bar. Low friction radial bearings are disposed between the dowel pins and the roller sections. Low friction thrust bearings are axially disposed between the roller sections and the bearing surfaces of the support yoke. The spring acts against the support yoke to press the roller sections against the rack bar, causing the rollers to separate from each other and thereby defining a gap therebetween and pressing the washers against the bearing surfaces of the support yoke.

    • The present invention relates to a complementary transistor circuit and, an amplifier using it, and in particular, to a video amplifier for amplifying video signals and a high-definition CRT display device. In amplifying inputted video signals by using a multiplexer, a gain controller and a current mirror amplifier, each element circuit is formed by using complementary transistor circuits. Circuit simplification is thus attained. In addition, higher precision and band broadening has been realized owing to adoption of a current operation. Further, the present invention makes it possible to eliminate direct from the high voltage output completely by providing a low-voltage output circuit for feedback having a similar relationship with respect to the high-voltage video output stage of the video amplifier, thereby performing negative feedback via a sample-and-hold circuit. This also serves to broaden the bandwidth and reduce power dissipation.
