  • Patent number: 6988302
    Abstract: A system for verifying the quality of a pressing operation of a press-fit part onto a receiving portion of a receiving assembly. The system is applicable to the installation of a bearing cup onto a shaft, or a valve seat into a cylinder head. A probe measures a predetermined dimension of the press-fit part to establish a first measurement value. In the case of a valve seat installed a receiving pocket of a cylinder head, a measuring probe is inserted into the receiving pocket of the cylinder head to measure its depth. The depth is recorded as a second measurement value. The valve seat is then pressed into the pocket, and the residual depth is measured to determine the distance between the outermost surface of the pressed in valve seat and the outer surface of the receiving pocket. A computation compares the depth of the pocket against the thickness of the valve seat to determine a difference which is then compared to the residual depth.

  • Patent number: 6659867
    Abstract: A gaming machine has a principal display that displays a plurality of symbols in varying and stopped states. The player is rewarded when the stop state corresponds to a specific stop state. A predictive display displays whether the specific stop state is to be displayed. Start and stop devices are manipulated by a player, and a controller determines whether the specific stop state is to be permitted and a predictive display mode based on the result of the determination. The controller determines whether the likelihood of appearance of the specific stop state is changeable in conjunction with a change in the game resulting from the passage of time. The player adjusts the stop manipulation while confirming changes of the predictive display or expecting the appearance of a known predictive display. In this manner, an effective variable demonstration is achieved, and the fun of the game is enhanced.

  • Patent number: 6170326
    Abstract: Processes and apparatus for signal analysis enable “pass/fail” determinations to be made with respect to noisiness of a mechanical or electrical system under test, particularly the presence of bumps and nicks in gear train systems under test. In a process aspect, for a gear system, a torque input is applied. A first signal responsive to the torque applied to the gear system under test is produced, which is converted to digital data responsive to a first correlation between the first signal and time. Peaks in the digital data are measured to determine whether they exceed a predetermined threshold magnitude. The peaks that exceed the predetermined threshold magnitude are subjected to harmonic analysis, the results being compared to gear tooth harmonics to determine whether the peaks constitute an anomaly. Such an anomaly is a bump or a nick on a tooth of the gear system under test.
