Abstract: In the adjustment method of optical coupling for an optical integrated circuit according to the present disclosure, the optimal adjustment position of optical coupling is determined on the basis of, for example, a sum of a plurality of photocurrents at electrodes on arm waveguides respectively formed on the plurality of MZIs in the polarization-multiplexing IQ modulator. According to the maximum value of the sum of the plurality of photocurrents, the light condensing spot position is adjusted to the center position of the end face core of the optical waveguide of the integrated chip. Typically, the light condensing spot position is adjusted to the center of the end face core by displacing the two input lenses.

Abstract: This invention provides a sticky cleaner used for removing organic dirt deposited on an article surface. The sticky cleaner comprises a dirt-collecting member that collects the organic dirt upon contact with the article surface. The dirt-collecting member has an acrylic PSA in an area that comes in contact with the article surface. The dirt-collecting member exhibits a hardness of 90 or less in the area that comes in contact with the article surface.

Abstract: A wax pattern forming die to form a wax pattern is first fabricated, and a molten wax is poured into a cavity in the wax pattern forming die to fabricate the wax pattern. Subsequently, the wax pattern is bonded to a casting sprue pattern made of the wax and fabricated separately from the wax pattern to fabricate an integrated pattern, a surface of the integrated pattern is coated with ceramics, sintering is effected, then the integrated pattern is molten and effused to fabricate a mold to cast a casting with a casting sprue. Further, a molten metal is poured into the mold and cured, then the mold is crushed to take out the casting with the casting sprue, and the casting sprue is cut off from the casting with a casting sprue to fabricate a casting.

Abstract: A biological information detection device includes a case that is provided with a sensor that detects biological information about a subject, a band that secures the case on the subject, and an adjustment mechanism that pulls the band in a first direction when a rotary member that is supported by the case has been rotated, the first direction being a direction in which the side of the case that is situated opposite to the subject comes in contact with the subject.

Abstract: Provided is a portable adhesive cleaner with superior portability, and which is small and easy to manage. In order to prevent shaking of an adhesive tape roll (R) in a protective case (3) when attaching the protective case (3) to a cleaning tool main unit (2), a disc-shaped stopper (4) of larger diameter than the maximum outer diameter of the adhesive tape roll (R) is provided at the tip of a supporting shaft (21), and a positioning means is provided between the stopper (4) and the bottom lid (36) of the protective case (3).

Abstract: A surface fastener and a product attached with the same surface fastener, having a structure for reducing a sound generated upon separation of a surface fastener member itself and capable of reducing a sound generated upon separation of the product attached with the same surface fastener. A sheet material is attached to a rear surface of a flat base material of a surface fastener member comprising an engaging-element-formation region having multiple engaging elements on a front surface of the flat base material and an engaging-element non-formation region having no engaging elements or comprising a sewing region and a non-sewing region. The sheet material has apparent density of 0.5 g/cm3 or less at least in a region corresponding to the engaging-element-formation region or the non-sewing region as sound transmission restricting means, or has at least one through hole as the sound transmission restricting means. Further, the apparent density of the flat base material is set to 0.5 g/cm3.
