Abstract: There is provided a sliding apparatus having low frictional resistance with a snow surface or an ice surface and excellent sliding properties. A sliding apparatus for sliding on a sliding object (snow surface or ice surface) has a sliding surface (1) contacting the sliding object. The sliding surface (1) is divided into a plurality of regions (1A, 1B, 1C) different in the surface arithmetic mean roughness Ra, and the plurality of regions (1A, 1B, 1C) is arranged in order along the longitudinal direction. Among the plurality of regions (1A, 1B, 1C), the surface arithmetic mean roughness Ra of a front region (1A) which is a region first contacting the sliding object in sliding is smaller than the surface arithmetic mean roughness Ra of the rear region (1B) positioned rearward in the sliding direction with respect to the front region (1A).

Abstract: A load sensor and load detector for detecting the weight of tiny substances such as viruses or bacteria and includes a resonance generator causing a vibrating unit to resonate, a load sensor, and a voltage detector that detects change in induced electromotive force in a pick-up. The load sensor includes the vibrating unit, pick-up, and a substance adsorbent. The vibrating unit includes a magnetostrictive element capable of resonating. The pick-up generates an induced current using inverse magnetostrictive effect of the magnetostrictive element resulting from the vibrating unit vibrations. The substance adsorbent is provided at the vibrating unit, is composed of an antibody to viruses or bacteria and at least partially covers the vibrating unit. The pick-up is composed of a coil with the vibrating unit arranged inside the coil. The vibrating unit is formed by bonding the magnetostrictive element and a soft magnetic body to each other.

Abstract: Provided are a sliding instrument having a low frictional resistance to the snow surface, the ice surface, or the water surface and having excellent sliding performance and a method for manufacturing the sliding instrument. A sliding instrument to slide on snow, ice, or water includes a sliding surface (1) to come into contact with the snow surface, the ice surface, or the water surface, and the sliding surface (1) has a surface roughness Ra of 1.0 ?m or less.
