Abstract: A hydrogen gas supply system comprises a storing unit that stores hydrogen, a communication unit that receives at least either of burden information indicative of an environmental burden exerted during manufacturing of hydrogen externally received by the storing unit and quality information indicative of quality with respect to the hydrogen externally received by the storing unit, a user interface unit that provides an output in accordance with the at least either of the burden information and the quality information with respect to the hydrogen supplied from the storing unit to the user, and a controller that controls the user interface unit based on an amount of the hydrogen received by the storing unit and the at least either of the burden information and the quality information, which is received by the communication unit.

Abstract: A tilting pad bearing includes: a bearing housing that is cylindrical which includes inner and outer rings that are concentrically located, arc springs located side by side in a circumferential direction between the rings, and slits that separate the inner ring, the outer ring, and the arc springs from each other; bearing pads that are, on an inner peripheral side of the bearing housing, located side by side in the circumferential direction; and an oil feeder that feeds lubricating oil into gaps between the bearing pads, the gaps extending in the circumferential direction, and into the slits. The bearing housing includes divisional cylindrical bodies that are located side by side in the circumferential direction and are coupled together. Each of the divisional cylindrical bodies includes two divisional surfaces that are coupled to another divisional cylindrical body. The two divisional surfaces are located in a manner to avoid the arc springs.

Abstract: A multichannel streamer cable includes a plurality of vibration receiving units connected in series. The vibration receiving units each include a geophone that receives vibration of a sound wave under water, an amplifier that amplifies a signal output from the geophone, an AD converter that digitizes the signal amplified by the amplifier, and a processing section that performs processing for causing an internal memory to store, as measurement data, a digital signal obtained by digitizing the amplified signal by the AD converter.

Abstract: The present invention provides an organic solvent-based concentrated ink composition for gravure printing which shows good print density, printability, and laminatability even in gravure printing using a shallow cylinder. The organic solvent-based concentrated ink composition for gravure printing mainly includes a pigment; binder resin; and an organic solvent. The pigment includes at least one of an organic pigment and an inorganic pigment. The binder resin includes polyurethane resin. A solution obtainable by dissolving 30 parts by mass of the polyurethane resin in 70 parts by mass of the organic solvent has a viscosity of 100 to 500 mPa·s/25° C. The concentrated ink composition has a viscosity of 10 to 1000 mPa·s/25° C. and has a viscosity in gravure printing of 12 to 23 s/25° C. in terms of the efflux time from a Zahn cup #3.

Abstract: Disclosed is a polyurethane resin which is a reaction product of a high molecular weight polyol compound having a molecular weight of 3,000 to 10,000, a low molecular weight polyol compound having a molecular weight of not more than 200, an organic diisocyanate compound, a chain extender, and optionally a reaction terminating agent, wherein the whole of the high molecular weight polyol compound and the low molecular weight polyol compound has an average molecular weight of 1,500 to 2,700; the isocyanate index (I.I.) of the organic diisocyanate compound to the high molecular weight polyol compound satisfies the following condition: I.I.>2.0; and the nitrogen content of the polyurethane resin derived from the isocyanate group of the organic diisocyanate compound is from 1.30 to 1.95% by weight.

Abstract: A modified chlorinated polypropylene which has superior properties is obtained by the reaction of a chlorinated polypropylene having a molecular weight in the range of from 5,000 to 500,000 with a polyurethane having a molecular weight in the range of from 600 to 200,000. The modified chlorinated polypropylene exhibits excellent adhesion to various kinds of base film and a satisfactory performance with respect to such after-treatments as lamination, boiling and retort processes, and therefore is useful as a binder resin for printing ink or other coating compositions.
