Abstract: Provided is a cell-containing container including nerve cells and a medium, in which the nerve cells adhere to a culture surface of the cell-containing container, an adhesion area between the nerve cells and the culture surface is 0.5 mm2 or more per 80,000 nerve cells, and a concentration of glucose in the medium is 1 g/L or higher.

Abstract: A drying suppression device including: a main body housing a well plate; and an openable/closable lid provided on the main body, the main body including: a holder section that holds the well plate; a liquid storage tank that stores liquid; and a support section that supports the holder while keeping the holder section away from an inner bottom surface of the liquid storage tank, wherein, with the lid being closed, an inner space surrounded by the liquid storage tank and the lid communicate with an outside space.

Abstract: A cell-containing container includes at least one recessed part accommodating cells, in which the cells adhere to a bottom surface of the recessed part, and a cell density in a first region of the bottom surface is 250 to 20,000 cells/mm2, and a cell density in a second region surrounding a periphery of the first region is less than 250 cells/mm2.

Abstract: A coater used also as a wiper used to apply a liquid solution such as a functional solvent onto glass panes and construction materials, wipe off water and stain, and stick film on the smooth surfaces of the glass panes, comprising a holding part and a thin plate-like spatula part. Since the spatula part comprises a folded part formed at the tip part thereof and the folded part is elastic, even if a member to be coated has curved surfaces and irregularities, the spatula part is flexibly fitted to the surface thereof. If a cloth-like coating member (or wiping cloth) soaked with a coating agent is detachably installed on the entire outer periphery of the spatula part, a same coater body can be used by changing the material and thickness of the coating member according to the types and coating purposes of the coating liquid solution and the members to be coated and the purpose of coating. Accordingly, the coater can have such an advantage that the required number of coater bodies is only one.

Abstract: A brush is provided in which a brush body is formed with a circumference of a fur bundle being surrounded with a fabric material and a tip end face of the fur bundle being extruded and exposed.

Abstract: A brush made by twisting a plurality of core elements and tightly holding elongated cloth pieces in gaps between the twisted core elements. In each of the gaps, a plurality of stacked elongated cloth pieces are held together. The elongated cloth pieces are made from a fabric woven with ultra-fine fibers to make loops, or from a moquette fabric of ultra-fine fibers whose tips are raised. The brush can be used either as a washing tool or as a painting tool which is adaptive to surfaces of all types of articles, including hard articles and delicate and soft articles, and performs an excellent washing or painting effect.

Abstract: The cleaning and polishing pad of this invention has extremely fine microfibers ranging in thickness up to one denier. In addition, the microfibers have a polygon configuration which provides edges that enhance the cleaning ability of the fibers. The pad can be attached to the rotating disk of a polisher by a bolt extending through an aperture in the pad. Alternatively, the pad can fit over the rotating disk like a shower cap where an elastomeric band is provided around an inner opening of the pad.
