Abstract: A multilayer ceramic capacitor includes a base body including dielectric ceramic layers and internal electrode layers stacked in a thickness direction, and a pair of external electrodes on first and second end surfaces and electrically connected to the internal electrode layers. The dielectric ceramic layers include, as a main component, crystal grains including a perovskite complex oxide including barium and titanium, and a rare earth element, and include, in a cross section including the thickness direction, a rare earth element high-concentration region in an area proportion of about 50% or more, the rare earth element high-concentration region including the rare earth element in a molar ratio of the rare earth element to titanium of about 0.04 or more and about 0.30 or less.

Abstract: A conveyance seat includes a seat cushion having a urethane pad member, a bead foam molding member harder than the urethane pad member, a skin material, and a seating sensor sensing a seated occupant's seating load, in which the urethane pad member is formed with a first through hole penetrating the urethane pad member in a height direction, the bead foam molding member is formed with a second through hole penetrating the bead foam molding member in the height direction and at least a part of the second through hole is at a position overlapping the first through hole in a top view, the seating sensor includes at least a sensor main body portion and a cable portion energizing the sensor main body portion or transmitting a signal of the sensor main body portion, and the cable portion is inserted through the first through hole and the second through hole.

Abstract: The purpose is to suppress positional misalignment between the diffusion layer and the frame. The manufacturing method of an electrode frame assembly for fuel cell comprises the steps of: (a) placing a frame and a diffusion layer to be stacked on each other; and (b) punching out the diffusion layer and the frame in the stacked state to form in the frame an opening in a shape matching with the punched-out diffusion layer.

Abstract: A novel and original hair treatment apparatus which is capable of simply and properly treating a tress of hair while applying an ultrasonic wave and/or negative ions to the tress of hair with no use of any head hair nutrient, and which, in a case where hair treatment is to be made using a permanent wave agent or a straight permanent wave agent and/or an appropriate head hair nutrient, is capable of simply and properly treating the tress of hair while applying an ultrasonic wave and/or negative ions to the tress of hair with the permanent wave agent or the straight permanent wave agent and/or the appropriate head hair nutrient being caused to sufficiently penetrate into the tress of hair.

Abstract: A wet paint spray booth treating agent includes sepiolite alone or further accompanying cationic polymer or amphoteric metal compound. In a method of treating a wet paint spray booth, the sepiolite alone or further accompanying the cationic polymer or the amphoteric metal compound is added. The wet paint spray booth treating agent and a method of treating a wet paint spray booth improve the effect of reduction in tackiness and decrease the load of agents to prevent the corrosion of furnishings. The sepiolite is a fibrous mineral containing chain structures having lots of micropores so that the sepiolite can reduce the tackiness of the paint due to reaction with the particles of the paint in such a manner to adsorb the particles in the micropores thereof.

The sepiolite is a fibrous mineral containing chain structures having lots of micropores so that the sepiolite can reduce the tackiness of the paint due to reaction with the particles of the paint in such a manner to adsorb the particles in the micropores thereof. Since both the particles of the paint and the particles of the sepiolite are negatively charged, when the cationic polymer or the amphoteric metal compound is added in combination with the sepiolite, the electrical repulsion is reduced so that the particles of the paint become easy to be adsorbed to improve the effect of the reduction in the tackiness.
