A grip for the handle of a golf club having multiple two layer panels that are wrapped about an underlisting sleeve. The edges of the panels are adhesively sealed together. The grip reduces impact and shock and provides a feeling of tackiness in the manner of a spirally wrapped polyurethane-felt grip while allowing the use of multiple color panels and easy instillation onto a golf club shaft.

A grip for the handle of a golf club having a single polyurethane-felt panel that is wrapped about an underlisting sleeve. The side edges of the panel are adhesively sealed together. The unitary grip reduces impact shock and also provides a feeling of tackiness in the manner of a spirally wrapped polyurethane-felt grip.

An electrostatic transducer for micromechanical resonators, in which the electrode gaps are filled with a dielectric material having a much higher permittivity than air. This internal electrostatic transducer has several advantages over both air-gap electrostatic and piezoelectric transduction; including lower motional impedance, compatibility with advanced scaled CMOS device technology, and extended dynamic range. In one aspect, in order to minimize energy losses, the dielectric material has an acoustic velocity which is matched to that of the resonator material. Internal electrostatic transduction can be adapted to excite and detect either vertical modes (perpendicular to the substrate) or lateral modes (in the plane of the substrate). Its increased transduction efficiency is of particular importance for reducing the motional resistance of the latter.

An object of the present invention is to provide an ink jet print head configured to reduce the inclination of an ink ejection direction to make improper print conditions such as stripes and density unevenness unnoticeable. To achieve the object, an individual wire is extended to lie under a common wire. Thus, wires under ink channels arranged on the respective opposite sides of a pressure chamber 40 are made symmetric. Consequently, an equivalent step structure is provided at the bottoms of the ink channels arranged on the respective opposite sides of a pressure chamber 40.

A probe resistance measuring method includes measuring first resistances at three or more nodes by making contact at least a part of a plurality of probes of a probe unit with three or more pads for resistance measurement based on a first correspondence relation. The measured resistances are stored as a first measurement result and contact resistances of the plurality of probes of the probe unit are calculated based on the first measurement result.
