Abstract: Provided is a water absorbent sheet retaining mat which can retain a water absorbent sheet easily and surely. A water absorbent sheet retaining mat for retaining a water absorbent sheet having a first polygonal contour, includes: a mat member having a second polygonal contour defined by mutually opposing a first main plane and a second main plane; and at least one retaining member having a slit member including at least one slit formed in a top surface at a predetermined height from the first main plane for accepting a part of perimeter of the water absorbent sheet being inserted therein, wherein the water absorbent sheet is laid on the first main plane, and then the above purpose is accomplished.

Abstract: A connector for an animal has a stopper mechanism for enabling or disabling a slide bar to be pushed back. The connector for an animal includes a hook member; a stem portion extending from an end of the hook member in a first direction; a slide bar for being reciprocated in the first direction to open or close the hook member; a lock member for being installed around the stem portion to rotate therearound with the first direction as a rotation axis; and an operating member for being connected to the slide bar so as to protrude in a second direction perpendicular to the first direction, the lock member including a cylindrical member with a cylindrical space formed therein for housing the stem portion rotatably and projection extending from a part of the hook member side end of the cylindrical member toward the hook member by a predetermined length.

Abstract: A coupler includes: a hook portion; a stem portion extending from an end portion of the hook portion in a first direction; a slide bar closing and opening the hook portion by reciprocating in the first direction; a connection ring rotatably connected to an end of the stem portion with respect to the first direction, having a predetermined contour, and extending in a second direction perpendicular to the first direction; at least one projection extending from an outer circumferential portion of the connection ring in the second direction by a predetermined length; and an operation member connected to the slide bar and extending toward the connection ring. The operation member abuts only the projection when being moved in the first direction.

Abstract: Provided is a cat playing tool expected as an optimum communication tool between cats and people, employing means for optimally producing both of a relaxing effect obtained by an Actinidia polygama powder and an effect of deodorizing bad odor by a deodorant component. A cat playing tool includes a printed layer having an Actinidia polygama powder, a deodorant component, and a binder applied thereto, and is configured so that the above-described printed layer is held by at least one of two sheets (a first sheet and a second sheet) and that the above-described first sheet and the above-described second sheet are joined together at the peripheries thereof so as to form a bag shape holding the above-described printed layer therein.

Abstract: There is disclosed a flip chip semiconductor integrated circuit, which comprises an internal cell, an I/O buffer as an interface between the internal cell and an external unit, a solder ball, a GND or power supply wire, and an I/O buffer unit arranged on a chip. In this case, the components except the I/O buffer unit are formed in a unit and arranged on the chip, and the I/O buffer unit includes a signal solder ball for transferring signals with the external unit, an I/O buffer having a signal terminal connected to the signal solder ball, a first I/O buffer GND wire connected to a GND terminal of the I/O buffer, and a first I/O buffer power supply wire connected to a power supply terminal of the I/O buffer.
