The invention relates to a response performance test method and system of a microswitch. The method comprises the following steps: inputting a multi-pulse trigger sequence to a microswitch contact and collecting contact response original data; performing digital filtering processing on the contact response original data to obtain contact response time sequence data; comprehensive response time parameters including contact mechanical action starting time, electrical initial contact time and electrical stable contact time are calculated according to the contact response time sequence data; performing temperature compensation and contact rebound characteristic extraction on the comprehensive response time parameter to obtain contact rebound characteristic evaluation data; according to the contact rebound characteristic evaluation data and the comprehensive response time parameter, the response performance stability of the microswitch under the high-frequency operation condition is calculated, and a reliability evaluation result is generated. According to the invention, the problem of time sequence measurement error caused by the influence of contact jitter in the traditional test is effectively solved, and the accuracy and consistency of contact response time measurement are remarkably improved.

A golf ball having contact time, CT143 of greater than or equal to about 400 microsecs, a Coefficient of Restitution, COR143 of greater than or equal to about 0.720, a TD5, TD6, or TD7 of from about 310 to about 320 yards when measured under each respective Test Condition, and a TD2 vs. Headspeed ratio of greater than about 2.3 when measured under Test Condition 2.

The invention relates to a method for determining a contact wear of a switching device (1) comprising an anchor (2) that is moved by means of a magnetic drive (3) in a tripping event, at least one fixed contact (7) and at least one moveable contact (8) mechanically connected to the anchor (2). The method comprises the steps of: - determining a contact time (10) when fixed contact (7) touches the moveable contact (8), - determining an inductance (11) of the magnetic drive (3) at the contact time (10), - determining the contact wear by comparing an initial inductance (12) with the inductance (11) at the contact time (10). Furthermore, a switching device (1) is specified.

The present application provides a lift pin contact position adjustment method, a lift pin contact position detection method, and a substrate placement mechanism that can automatically and with high precision adjust the contact position of a lift pin with respect to a substrate placed on a substrate placement table. The contact position adjustment method includes the steps of: placing a substrate on the substrate placement table; in a state in which the substrate is adsorbed by applying a voltage to an electrode of an electrostatic chuck; generating a torque waveform that indicates the time variation of the torque of a motor when moving the front end of the lift pin from a lower end position below the placement surface to an upper end position above the placement surface, for each of a plurality of voltages; calculating a contact time point that is the time at which the lift pin contacts the substrate, from the plurality of torque waveforms; calculating the contact position from the contact time point and the speed of the motor; determining whether the contact position is within an appropriate range; and automatically adjusting the contact position if it is determined that the contact position is outside the appropriate range.
