Abstract: A cover for an automobile engine covers a crank pulley and an auxiliary drive belt of an engine arranged in an engine room with the crank pulley and the auxiliary drive belt being in a posture facing a front direction of a vehicle body. The cover includes a reinforcing body that includes a fastening part attaching to the engine and is integrated with a sound-absorbing main body.

Abstract: A deterioration diagnosis apparatus is for a mechanical apparatus including a power transmission mechanism that transmits power via a gear. The deterioration diagnosis apparatus includes: a storing unit that stores, in advance, a trend of change along with the operation of the mechanical apparatus, in consumption rate of an additive contained in lubricant used for the gear; and a determination unit that determines the period to be taken for the consumption rate of the additive to reach a predetermined value, based on the trend of change in the consumption rate of the additive.

Abstract: An alkaline water electrolysis diaphragm includes: a polymer porous layer containing at least one polymer compound selected from polyether sulfone having a contact angle of 20 to 90° and polysulfone having the contact angle of 20 to 90°; and an organic fiber fabric layer coupled to the polymer porous layer. The polyether sulfone having the contact angle of 20 to 90° is at least one polymer compound selected from the group made of polyether sulfone, hydrophilic polyether sulfone, cationic polyether sulfone, and cationic hydrophilic polyether sulfone. The polysulfone having the contact angle of 20 to 90° is at least one polymer compound selected from the group made of polysulfone, hydrophilic polysulfone, cationic polysulfone, and cationic hydrophilic polysulfone.

Abstract: A hydrophilic filtration membrane having high chemical resistance, high strength, high water permeability and high blocking performance, and being superior in fouling resistance is provided. A hydrophilic filtration membrane containing a hydrophilic polyethersulfone having a contact angle of 65 to 74 degree, a molecular weight of 10,000 to 100,000, and the number of hydroxy groups of 0.6 to 1.4 per 100 polymerization repeating units. The hydrophilic filtration membrane may additionally contain a polyvinylpyrrolidone having a molecular weight of 10,000 to 1,300,000.
