Abstract: To provide a thin film capacitor capable of achieving low impedance over a wide frequency band. A thin film capacitor includes: a capacitor layer having a structure in which internal electrode layers and dielectric layers are alternately stacked; a redistribution layer stacked on the capacitor layer; and external terminals. The redistribution layer includes a wiring pattern connecting the external terminal and the internal electrode layers and a wiring pattern connecting the external terminal and the internal electrode layers. A distance between first and second via conductors is smaller than distance between second and third via conductors and is smaller than a distance between first and fourth via conductors.

Abstract: Abstract Provided is an oil-based cosmetic preparation which retains a smooth feel. Provided is an oil-based cosmetic preparation containing the following components (A), (B), and (C): (A) a cellulose derivative having a cellulose skeleton in a main chain, in which 67 mol % or more in total hydroxyl groups are substituted with a group —O-M-R, wherein M represents CH2 or a carbonyl group C?O, and R represents a straight or branched alkyl or alkenyl group having 3 to 40 carbon atoms; (B) an ester oil which is liquid at 25° C.; and (C) a hydrocarbon oil which is liquid at 25° C., in which a weight ratio (B)/(C) of the component (B) to the component (C) is 8/1 to 1/4.

Abstract: Ether compounds, which are useful as solvents, cosmetics, detergents, lubricants, emulsifiers and so on, are produced by reacting (a) a hydroxy compound with a carbonyl compound of (b) a carbonyl compound under hydrogen atmosphere in the presence of a catalyst with ease and at a low cost. The reaction is carried out while removing out produced water by using a dehydrating agent during the reaction; by distilling off the water by azeotropic dehydration and the like; or by blowing gases such as hydrogen gas to flow through the reaction system.
