摘要:
A nonaqueous secondary battery includes a current cutoff mechanism that cuts off a current in a short period of time in response to a rise in pressure inside a battery outer body in at least one of a conductive path through which a current is taken out from a positive electrode plate to outside of the battery and a conductive path through which a current is taken out from a negative electrode plate to outside of the battery. At least one type selected from an oligomer containing a cyclohexyl group and a phenyl group, a modified product of the oligomer containing a cyclohexyl group and a phenyl group, a polymer containing a cyclohexyl group and a phenyl group, and a modified product of the polymer containing a cyclohexyl group and a phenyl group is present on the surface of the positive electrode plate.

A power transmission belt formed with an encoder on its surface, method of manufacturing the power transmission belt, and a load detection system using the power transmission belt. The power transmission belt comprises a band-like magnetic rubber layer provided in a part of a belt layer structure of the power transmission belt which transmits power to an auxiliary machine of an automobile engine along the longitudinal direction of the belt layer structure. The surface of the magnetic rubber layer constitutes a multipolar magnetized surface alternately provided with N-poles and S-poles along the longitudinal direction of the belt layer structure, the surface of the magnetic rubber layer is capable of outputting signals for calculating load applied to the belt layer structure by the auxiliary machine to a plurality of magnetic sensors provided along the longitudinal direction of the belt layer structure, and one of the sensors is provided at a position where the auxiliary machine is provided.

A cylinder head gasket for sealing between a cylinder block and a cylinder head, composed of a composite base plate, the composite base plate comprising a core material plate and a compound layer formed on the front and back surfaces of the core material plate, the compound layer being formed by coating compound materials which contain a rubber and a fiber material. The cylinder head gasket is comprised of an annular groove which is formed by pressing the corresponding region around the cylinder bore of the compound layer, and a bead projecting from the surface of the compound layer which is formed by inserting the rubber material into the annular groove.

A cylinder block 3 of an engine 1 is formed by assembling an inner block member 10 and an outer block member 15. The inner block member 10 includes an upper deck portion 7 integrated with a cylinder liner portion 8. The outer block member 15 includes a cylinder outer wall portion 12. The cylinder head 2 is fastened to an upper deck portion 7 with head bolts 31. The cylinder outer wall portion 12 is fastened to the upper deck portion 7 with block fastening bolts 32 at an opposite side of the upper deck portion 7 with respect to the cylinder head 2. The head bolts 31 and the block fastening bolts 32 are threaded with the upper deck portion 7 from the opposite sides with respect to each other. As a result, deformation of the upper deck portion 7 and inclination of the cylinder liner portion 8 due to fastening of the bolts 31, 32 are reliably prevented.

An electric double layer capacitor is provided with a cell, in which a pair of polarizable electrodes, which are impregnated with an electrolyte, are disposed in opposition on either side of a separator; wherein the polarizable electrodes are provided with collector electrodes, and a peripheral portion of the cell is sealed by a sealing member composed of synthetic resin. The collector electrodes are composed of an alloy made of crystal grains of differing components and the collector electrodes pass through the sealing member while in intimate contact with the sealing member, extending to the outside of the sealing member. A metal plated layer made of crystal grains of a single component is formed on those locations on the collector electrodes that pass through the sealing member.

A device for controlling the rotation speed of a cooling fan of an internal combustion engine in a vehicle such as an automobile, wherein the fan is driven by a hydraulic motor powered by an operating fluid supplied by a pump directly driven by the engine, wherein the device controls partial relief of the hydraulic fluid supplied from the pump toward the motor so that, in a low engine revolution speed range, the ratio of the partial relief is decreased as the engine temperature increases, but in a high engine revolution speed range, the ratio of the partial relief is increased as the engine revolution speed increases.
