A cylinder block for an engine has a cylinder assembly having a plurality of cylinders, each corresponding to one of a plurality of pistons. A block body has an outer wall accommodating the cylinder assembly, a crankcase accommodating the crankshaft, and a plurality of partitions. The partitions divide the space in the crankcase into a plurality of crank chambers. The number of the crank chambers corresponds to the number of the cylinders. The outer wall, the crankcase, and the partitions are formed integrally. A partition through portion is formed in a predetermined one of the partitions to connect an adjacent pair of the crank chambers. The partition through portion opens toward the cylinders.

Disclosed is a power transmission apparatus to detect the deterioration state of a timing belt in use, thereby making it possible to detect at a high accuracy whether or not the timing belt reaches an exchanging time. The power transmission apparatus comprises a crankshaft pulley, an intake camshaft pulley, and a timing belt wound around the crankshaft pulley and the intake camshaft pulley. The timing belt contains a stress light emission material capable of emitting light when receiving an external force. The power transmission apparatus further comprises an optical sensor and an ECU. The optical sensor is disposed to measure light emitted from the timing belt. The ECU is operative to judge whether or not the timing belt is deteriorated and to judge that the timing belt reaches the exchanging time when the timing belt is judged to be deteriorated.

An electric double layer capacitor including a separator, a pair of polarizing electrodes disposed opposite to each other with the separator interposed therebetween, an electrolytic solution impregnated in a pair of the polarizing electrodes and the separator, an exterior cover and an exterior case for accommodating the separator, a pair of the polarizing electrodes, and the electrolytic solution, and a gasket disposed between the outer circumferential part of the exterior cover and the inner circumferential part of the exterior case, the storage space formed by the exterior case and the exterior cover being hermetically sealed by inwardly bending the opening tip portion of the exterior case, is characterized in that no folded-back part is provided at the outer circumferential part of the exterior cover, and the gasket is polyether ether ketone.
摘要:
In an electric double layer capacitor including two plate-like polarizable electrodes stacked in layers via a separator and constituted by housing these in an outer packaging member, a contact area between a first polarizable electrode and the separator is different from a contact area between a second polarizable electrode and the separator, and the polarizable electrode with a smaller contact area is formed thicker than the polarizable electrode with a larger contact area. In addition, it is preferable that the first polarizable electrode and the second polarizable electrode have a generally equal volume.

An electric double layer capacitor has an electrode unit (10), an external lid (4), an external case, and a gasket (8) disposed between the external lid (4) and the external case (5). The external case (5) has an open end part that is bent inwardly with the external lid and the external case being disposed so that inner surfaces of the top wall and the bottom wall face each other, to hermetically close an accommodating space, formed by the external case and the external lid. The thickness of at least the circumferential wall of the external lid (4) is greater than the thickness of the external case (5). The circumferential wall of the external lid (4) extends substantially linearly toward the bottom wall of the external case (5), and the extending edge of the circumferential wall of the external lid (4) is buried in the gasket (8).
摘要:
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, a peripheral portion of the cell is sealed by a sealing member composed of synthetic resin, and the sealing member is formed by abutting two case halves. A manufacturing method for the capacitor includes a process step of providing at least one long slit in the collector electrodes; a step of forming the case halves formed by insert molding on the collector electrodes and filling the slit, the case halves comprising a recess, one side of which extends in the lengthwise direction of the slit and, the cell being fitted into a portion inward from the slit; and a step of joining the case halves by abutting the case halves and applying ultrasonic vibration either in a perpendicular direction or a diagonal direction with respect to the lengthwise direction of the slit.
摘要:
A solid electrolytic capacitor formed with a dielectric coating and a solid electrolyte layer successively formed on a surface of an anode body, wherein the solid electrolyte layer includes a conductive polymer containing at least a fluoroalkylnaphthalenesulfonate ion as a dopant. The conductive polymer can further contain a tetrahydronaphthalenesulfonate ion, a naphthalenesulfonate ion or a benzenesulfonate ion as the dopant. As a result, a solid electrolytic capacitor having a low ESR and a good heat resistance is provided.

摘要:
An electric double layer capacitor includes: a cell which includes a pair of polarizable electrodes impregnated with an electrolytic solution and disposed in opposed relation with a separator interposed therebetween; collector electrodes respectively attached to the polarizable electrodes; and a sealing member of a synthetic resin which seals a periphery of the cell. The collector electrodes extend outward of the sealing member through the sealing member in contact with the sealing member. The collector electrodes each have a rough surface portion which extends through the sealing member.
