    摘要: A method of manufacturing a spark plug includes the step of adjusting a spark gap in the spark plug. In the step, a ground electrode is repeatedly pressed, by a hammer, toward a center electrode. The hammer operates in a first mode when the size of the spark gap falls in a rough-process range which is above a predetermined value, and in a second mode when the size of the spark gap falls in a finish-process range which is between the predetermined value and a target value less than the predetermined value. The amount of pressing the ground electrode in any press stroke of the hammer in the second mode is less than that in any press stroke of the hammer in the first mode. The amount of pressing the ground electrode in every press stroke of the hammer in the second mode is equal to a fixed value.

    摘要: An electrical contact device (X1) includes a first contactor with contact portions (C1, C2) and a second contactor with contact portions (C3, C4). The device (X1) also includes an electrical circuit having a branch path (YA) provided by the contact portions (C1, C3) and a branch path (YB) provided by the contact portions (C2, C4). When closed, the branch path (YA) has a smaller resistance, and the branch path (YB) a greater resistance. In a closing operation, the first and second contactors approach each other. Then the contact portion (C1) and the contact portion (C3) contact with each other after the contact portion (C2) and the contact portion (C4) contact with each other. In an opening operation, the first and second contactors separate from each other. Then the contact portion (C1) and the contact portion (C3) separate after the contact portion (C2) and the contact portion (C4) separate.

    摘要: A tuning fork type vibrator including two arms and a base is supported by a supporting substrate mounted on a stem, and an oscillation limiting member formed from a ring-shaped rubber-like elastic body is mounted with its one face secured to the stem so as to surround the base. When an external vibration or impact is applied, the tuning fork type vibrator oscillates in response to the vibration or impact, but the oscillation range of the tuning fork type vibrator is limited by the presence of this oscillation limiting member, and thus bumping of the tuning fork type vibrator against the surrounding members such as the stem is prevented. Moreover, a gyro characteristic is not impaired, and a loss of the gyro function due to a stop of drive vibration does not occur.

    摘要: A tuning-fork vibration gyro includes a tuning-fork vibrator having two arms and a base portion, and a supporting portion located in a center of a rotational motion of the base portion caused by a vibration resulting from a Coriolis force. The supporting portion protrudes from two surfaces of the base portion opposite each other in a direction in which the vibration resulting from the Coriolis force occurs.

    摘要: The shape of drive electrodes and/or the shape of detection electrodes of a tuning fork type vibration gyro are made asymmetrical between the inside and outside of the arm, and between the surface and reverse face of the arm, to reduce the abnormal vibration and leaking output. The drive electrodes to be provided on the inside parts of the surface and reverse face of the first arm are formed smaller than the drive electrodes to be provided on the outside parts of the surface and reverse face thereof. The length of the detection electrode to be provided on the outside lateral face of the second arm is formed short. The drive electrodes to be provided on the surface and reverse face of the first arm are extended to the base side from the boundary position between the first arm and the base, and the detection electrodes to be provided on the surface and reverse face of the second arm are extended to the base side from the boundary position between the second arm and the base.

    摘要: A deflection yoke attached to a color cathode ray tube forming multiple electron beams arranged in line, and in particular a deflection yoke having convergence correction apparatus. Circuit components such as a plurality of resistors, variable resistors, and diodes are connected in parallel with vertical deflection coils. A part of a vertical deflection current flowing through the vertical deflection coils is diverted to the circuit components. Furthermore, the amount of the diverted current is made adjustable so that it will differ between a former part of a vertical deflection period and a latter part thereof. As a result, horizontal line misconvergence at upper and lower ends of the screen can be completely corrected.
