摘要： An angular velocity sensor having a tuning-fork structure comprising a first vibrator including a first actuator and a first detector each attached to a metal plate and joined orthogonally to each other, and a second vibrator including a second actuator and a second detector each attached to another metal plate and joined orthogonally to each other, the two vibrators being coupled by an electrode block to each other in a generally parallel relationship along the axis of detection of the sensor. The first and second detectors have a rectangular plate shape each holding a piezoelectric element. The rectangular plate shape has a lengthwise edge and a widthwise edge where the lengthwise edge parallel to the axis of detection of the sensor and is longer than the width wise edge. At least one of the lengthwise edges of the detectors has a beveled surface formed by removing metal at an angle from the lengthwise edge of the detector to balance the sensor.

摘要： An angular rate sensor of the type, using oscillation of piezoelectric elements, which includes a pair of sensor elements each including a vibratory piezoelectric detecting element and a vibratory piezoelectric drive element joined together by a joint member in longitudinal alignment and oriented substantially at right angles relative to each other, and a resilient joint member joining the pair of sensor elements at respective free ends of the drive elements so as to form, jointly with the sensor elements, a tuning-fork structure. The turning-fork structure has an improved joint structure between each of the driving elements and the resilient joint member, which has a thickness to width ratio of approximately 3:10 to 7:10 to enable the angular rate sensor to have a low resonance impedance and stable performance characteristics.

摘要： An angular rate sensor detects an angular rate which is produced when a mobile body such as a motor vehicle moves. The angular rate detecting device comprises at least two angular rate sensors housed in a case perpendicularly to each other. Each angular rate sensor comprises a pair of vibratory units which are interconnected by a connector in a tuning-fork configuration. The vibratory units of different angular rate sensors are vibrated at different frequencies. The angular rate sensors may be accommodated in a damper block, which may be housed in the case. Since the angular rate sensors are housed in the single case, the angular rate detecting device is compact in structure and small in size. With the angular rate sensors accommodated in the damper block, they are protected from resonance, crosstalk interferences, and noise, and hence can produce reliable detected output signals.

摘要： An angular rate sensor has a tuning fork structure composed of vibratory components. The vibratory components include piezoelectric drive and detection elements which are joined together into a tuning fork configuration, the drive and detection elements lying in respective orthogonal planes. Leads are electrically connected to the drive and detection elements, and lead terminals are electrically connected to the leads, respectively. The vibratory components are covered with a coating which is of a material having a lower elasticity than the elasticities of the vibratory components. The coating on the vibratory components effectively reduces the propagation of unwanted vibrations, thereby reducing output signal drifts.

摘要： A microscope for stereoscopically observing therethrough an object from an oblique direction comprises a first convergent lens group and two second convergent lens groups. The first convergent lens group is disposed with the optic axis thereof perpendicular to the object plane to collimate the light from each point on the object plane when the focal plane thereof is coincident with the object plane. The two second convergent lens groups have equivalent optical performances and are parallel-disposed so that the principal planes thereof are coincident with each other on the exit side of the first convergent lens group and that the principal planes thereof are disposed non-parallel by forming a predetermined angle with the principal plane of the first lens group.
