Title: Vertical torquer for gyrocompass
Inventor: HOJO TAKESHI
IPC: G01C19/38
Filed: 1989-01-20
Abstract: PURPOSE:To enable the attaching of a function as torquer to a driven pickup by adding a permanent magnet and a U-shaped core to the driven pickup. CONSTITUTION:A U-shaped core 60-1 which has a permanent magnet 60-2 for generating a DC magnetic field in an E-shaped core 8-1a is mounted, on the side opposite to a primary coil 8-1 pertaining to a secondary coil 8-2, onto a core 8-1a through connecting devices 60-3 and 60-4. Then, a magnetic field is made in a space where the coil 8-2 is located with the magnet 60-2. Now when a DC current runs to the coil 8-2, a force is generated between the coil 8-2 and the coil 8-1 by Fleming's rule of left hand. This enables application of a torque proportional to a current about a vertical shaft of a gyrocase 1 to which the coil 8-1 is mounted thereby enabling the obtaining of a function of a torquer at a low cost.

Filed: 1987-01-21
Abstract: PURPOSE:To make it possible to detect defective places in a chip easily by dividing power source wirings at the same potential in the chip, and leading out the wirings to bonding pads. CONSTITUTION:Along the inner peripheral part of a square semiconductor chip 1, 10 bonding pads P1-P10 are arranged. The pads are connected to power source wirings L1-L10, which are divided into 10 pieces, as many as the number of the pads. Therefore, the inside of the chip 1 can be electrically divided. A single or a plurality of power supply pads are used. The supplied potential is changed, and the potentials of the input/output pads are observed. Thus the internal constitution of the chip 1 can be considered. Therefore the positions of the yielded defects can be limited at least to the range of one over the number of division of the power source windings at the same potential.
