Abstract: A molded product is made by a process including a step of breaking a waterproof paper for printing paper to give a mixture of cellulose fibers and a polyolefin resin. The waterproof paper is obtained by laminating a base paper produced for printing paper with the polyolefin resin. An additional thermoplastic resin is added to the mixture if necessary. The mixture is then molded so that the ratio by weight of the base-paper-derived cellulose fibers to the total of the polyolefin resin and the additional thermoplastic resin is in the range of 51:49 to 75:25. A moisture-proof container for a light-sensitive material is also produced from a container and a moisture-proof lining layer that are molded so that the ratio by weight of base-paper-derived cellulose fibers to the total thermoplastic resins is in the range of 51:49 to 75:25. The container may comprise an antioxidant and an aldehyde-neutralizing agent.

Abstract: A rotary-body type throttle valve for a spark ignition internal combustion engine is disclosed. The valve includes a valve casing, an intake passage formed with a rotary-body recess portion, a valve element having a rotary-body shape which is rotatably fitted into the rotary-body recess portion of the valve casing, and a communication passage that permits an upstream intake passage and a downstream intake passage to communicate with each other is formed in the valve element. The upstream intake passage and the downstream intake passage sandwich the rotary-body recess portion of the valve casing. A through hole which is directed from the communication passage of the valve element in a direction intersecting a central axis of the communication passage and reaches only one of rotary outer surfaces of the valve element is formed in the valve element. This arrangement results in a reduced flow resistance by decreasing the size and number of vortices generated during partially opened states of the valve element.
