摘要： In an angular velocity sensor device, a vibration isolation member, a sensor support plate on which a tuning fork unit functioning as a vibrating type angular velocity sensor is mounted, a collar, a circuit board on which a circuit pattern is formed for driving the tuning fork unit and processing a signal output therefrom are provided by having a plurality of pins inserted, in this order, which extend from the bottom surface of a concave-shaped case. The circuit pattern and the tuning fork unit are connected with each other via a flexible printed circuit board. These components are accommodated inside the concave-shaped case. A cover is fitted in an open top of the case so as to completely seal the case. The angular velocity sensor device with the aforementioned arrangement does not suffer variation in the operational properties due to disturbance vibration and deterioration in the vibration isolation property. In addition, adverse effects of moisture and corrosive gas in the atmosphere on the operational properties are prevented, since air is prevented from entering the inside of the case.

摘要： The present invention relates to a ribbon feed mechanism for use in a heat transfer printer. The ribbon feed mechanism includes first, second, and third ribbon feed components fitted on a shaft, a friction plate mounted between the first and second ribbon feed components, a spring mounted between the second and third ribbon feed components, a cylinder which is in contact with the third ribbon feed component at one end thereof, and a ribbon feed presser for pressing the other end of the cylinder toward the third ribbon feed component. The rotational torque is always kept constant, and therefore no unmatching of colors occurs when the mechanism is applied to a printer.

摘要： The rotation angle-detecting device has a main rotator and two detecting rotators that rotate as the main rotator rotates. Each of the two detecting rotators has a magnet and a magnetic detector. As the detecting rotator rotates, a change occurs in magnetic lines of force from the magnet. From the change, the magnetic detector detects rotation of the detecting rotator. According to the rotation detected, the device determines the rotation angle of the main rotator. In addition, a ring-shaped ferromagnetic body is disposed around the magnet or the magnetic detector of the detecting rotator. The structure described above enables magnetic detection without disturbance in each magnetic field of the magnets, and even in a downsized structure, the device can detect the rotation angle with high accuracy.

摘要： The pendulum assembly comprises a permanent magnet disposed in the vicinity of a pendulum, a U-shaped yoke by which most of the magnetic flux of the permanent magnet is gathered and passes through, and a rotation shaft. The direction of axis of the rotation shaft is parallel to the direction of magnetic poles of the permanent magnet. Eddy current brakes are inserted into the spaces between one of the magnetic poles of the permanent magnet and one of the ends of the yoke, and between the other magnetic pole the magnet and the other end of the yoke. This construction achieves a more compact and shorter tilt sensor which is resistant to disturbances such as geomagnetism and other magnetic fields and vibrations.
