Abstract: The present invention relates to a buttocks wiping device 1 for wiping the buttocks with paper. The buttocks wiping device 1 includes a wiping arm 4 including a pressing unit 4a configured to press the paper against the buttocks, and a wiping arm drive unit 3 configured to cause the wiping arm 4 to move and perform wiping operation. The wiping arm drive unit 4 wipes, without attaching or inserting the paper to the pressing unit 4a, the buttocks with the paper being placed on the pressing unit 4a. Moreover, the buttocks wiping device 1 of the present invention includes a paper supply unit 17 configured to expose the paper. The wiping arm drive unit 4 drives the wiping arm such that the pressing unit 4a pushes up, from below, the paper exposed by a paper loading guide 17c of the paper supply unit 17.

Abstract: An oil concentration measurement system and method measure the concentration of oil over a wide concentration range and is applicable in a continuous measurement of oil concentration. A measurement-target liquid containing a known kind of oil component, absorbance spectrum is measured within a predetermined waveband where absorption of light is observed. If a predetermined criterion is met, a concentration value of the oil component is determined based on absorbance at a predetermined wavelength within the predetermined waveband and also on a first calibration curve showing relationship between the component concentration and absorbance at the predetermined wavelength.

Abstract: The present invention relates to a connector for flexible conductive line components suitable for a lower mounted profile in a device mounted on a printed circuit board. The connector comprises a metal plate, resilient spring portions, and connection terminal portions wherein the resilient portions, which allow the metal plate and individual contacts to accommodate and clamp a inserted flexible printed circuit parallel with respect to the printed circuit board, are disposed such that the lengthwise spring extension thereof lies in the parallel direction, leaving the height unaffected. The metal plate further comprises a substantially U-shaped transverse cross section which affords both a low mounting profile and a stable connection that experiences minimal bending.
