Provided is a high Cr Ni-based alloy welding wire with which tensile strength and weld cracking resistance of a welded portion, the integrity of the microstructure of a welded metal, and inhibition of scale generation are improved. The high Cr Ni-based alloy welding wire is configured to have an alloy composition comprising, by mass, C: 0.04% or less, Mn: 7% or less, Fe: 1 to 12%, Si: 0.75% or less, Al: 0.01 to 0.7%, Ti: 0.01 to 0.7%, Cr: 25.0 to 31.5%, Ta: 1 to 10%, and Mo: 1 to 6%, and as inevitable impurities, Ca+Mg: less than 0.002%, N: 0.1% or less, P: 0.02% or less, O: 0.01% or less, S: 0.0015% or less, H: 0.0015% or less, Cu: 0.08% or less, and Co: 0.05% or less, and the balance: Ni. Then, the high CrNi-based alloy welding wire is configured such that the contents of S, Ta, Al, and Ti satisfy the following relation (1) and the contents of Ta, Mo, and N satisfy the following relation (2):12000S+0.58Ta&#x2212;2.6Al&#x2212;2Ti&#xa3;19.3&#x2003;&#x2003;(1)Ta+1.6Mo+187N5.7&#x2003;&#x2003;(2).

The present invention provides a pointing input device, which sequentially outputs pointing position data indicating a pointing input position and push detection data from a push by the same pen or finger used for a pointing input. The pointing input device includes a display panel for displaying any pointing input information and an optical touch panel. The optical touch panel detects the pointing input in an input operation area, through which a display area is visible, and outputs the pointing position data. Piezoelectric substrates are attached to a transparent protective plate protecting the top surface of the display panel. When an operator pushes the transparent protective plate disposed at the lower part of the optical touch panel while carrying out the pointing input, the piezoelectric substrates output electric signals by which the push is judged. Then, the push detection data is outputted with the pointing position data.

A shaft seal having a high abrasion resistance is disclosed, by which the leakage of the gas from the high-pressure side to the low-pressure side can be reduced. In the shaft seal, flexible leaves are multi-layered to form a ring shape. The shaft seal is mainly arranged around the rotation shaft of a gas turbine or the like. The relevant turbine comprises a casing, a compressor, a rotation shaft, moving blades attached to the rotation shaft, and stationary blades attached to the casing in a manner such that the stationary blades face the moving blades, wherein the shaft seals are provided between a plurality of stationary blades and the rotation shaft wherein the leaves of each shaft seal contact the rotation shaft. Under the rated operating conditions, the top ends of the leaves slightly separate from the surface of the rotation shaft due to the dynamic pressure generated by the rotation of the rotation shaft. When the turbine is not operated, the top ends of the leaves contact the rotation shaft again due to the elastic restoring force of the leaves.
