Abstract: A sealing device capable of preventing turnover of a dust lip and damage to a dust lip caused by insertion of a shaft. A bumper portion (125) made of a rubber-like elastic body and reducing an impact that the dust lip (122) receives from the shaft when the shaft is inserted into the sealing device (100) is provided on the side opposite to the sealed area (O) with respect to the dust lip (122), and an inner diameter of a tip of the bumper portion (125) on an inner peripheral side is set to be larger than an outer diameter of a part of the shaft on which a main lip (121) and the dust lip (122) slide and to be smaller than an inner diameter of a part having the largest inner diameter in a portion connecting the main lip (121) and the dust lip (122).

Abstract: The invention intends to provide a cell culture apparatus which is able to realize an adequate culture according to the culture state of cells while alleviating the labor of an operator. The cell culture apparatus includes a culture bag for causing the cells to proliferate, a cell inoculation cassette (or culture bag as an antibody stimulating and proliferation culture vessel) for stimulating the cells by an inducer for the proliferation, a culture medium cassette for storing a culture medium supplied to the culture bag and the cell inoculation cassette, a CCD camera 88 for acquiring images of the cells in the cell inoculation cassette, and an image processing computer and an operation control computer for determining the culture state (proliferation capability and proliferation ability of the cells) of the cells from the images of the cells acquired by the CCD camera, and causing a culture operation to be carried out on the basis of the determination.

Abstract: A new connector that is reduced in size and has a higher density of contacts implemented therein is provided. This connector has a contact module arranged on a connector main body. The contact module is formed into a sheet structure, and a plurality of contacts are arranged therein. Further, the contact module is bent into a C-shaped structure along the extending direction of the contacts, and is implemented to the connector main body in this state. Contact points of the connector are energized by sets of a coil spring and two push pins arranged on both sides of the coil spring so that these contact points protrude from holes formed at the connector main body.

Abstract: The object of the present invention is to provide marine algae powder for food and drink or granulated substance thereof, wherein abundant nutritional ingredients and health functional ingredients of Porphyra marine algae and Undaria marine algae are preserved as they are, while the odor contained in the marine algae is effectively abated or reduced, or to provide a powdered drink or food containing the marine algae powder wherein the marine algae powder for food and drink or the granulated substance thereof is used. The present invention comprises making a marine algae powder for food or drink and granulated substance thereof where nutritional ingredients and health functional ingredients of Porphyra marine algae and Undaria marine algae are preserved as they are, while the smell of the sea of the marine algae is abated, by powdering Porphyra marine algae and/or Undaria marine algae, and mixing powdered tea leaf into the marine algae powder.

Abstract: A contact module includes: a strip base; and a plurality of first and second protrusions continuously extending from the first and second ends of the base, respectively. The second end is opposite to the first end. The first and second protrusions include the same materials as the base. Each of the first and second protrusions includes first and second contact portions, respectively. The base includes a sheet made of a metal material, an insulating film formed on at least one side of the sheet, and a film including a noble metal material formed on the insulating film. The film forms the first and second contact portions and circuit patterns. The circuit patterns are formed between the first and second contact portions. The first and second contact portions and the circuit patterns integrally form a plurality of contacts. Each of the contacts includes one of the first contact portions, a corresponding one of the second contact portions, and the circuit pattern therebetween.
