摘要:
A honeycomb structure 1 comprising a honeycomb segment bonded body 10 having a number of honeycomb segments 2 integrated on each bonding planes via bonding material layers 9 has a structure so that a number of cells 5 providing fluid flow channels are disposed in parallel in the direction of center axis thereof. The honeycomb structure 1 is constructed so that the porosity of an outer portion of the bonding material layers 9 (an area from the interface with the honeycomb segment-bonding plane to a point apart from that interface by a distance equivalent to 20% of the entire layer thickness) is smaller than the porosity of a central portion located inward of the outer portion, and so that the bonding material layers 9 have a compression Young's modulus along the Z-axis of 5 to 100 MPa.

There is disclosed a honeycomb structure 1 which is made of a ceramic material and in which a plurality of honeycomb segments 12 having cell structures 5 and porous outer walls 7 on outer peripheries of the cell structures 5 are integrated by bonding the outer walls 7 to one another with a bonding material, each of the cell structures being provided with a plurality of cells 3 constituting fluid channels divided by porous partition walls 2, wherein the bonding material contains a bio-soluble fiber. The honeycomb structure 1 of the present invention has a performance equivalent to that of a honeycomb structure in which a heretofore used ceramic fiber is contained.

Each of areas surrounded by a plurality of main holders of a first case panel faces an area surrounded by each holder of a second case panel, at least partially. Each main holder includes a wall projecting toward the second case panel to prevent separation of a memory card placed in the holder. This structure enables a storing case to stably hold a plurality of memory card without enlarging the case.

A variable valve timing control apparatus of an internal combustion engine, has a housing having a plurality of shoes and a vane member having a plurality of vanes dividing each working fluid chamber formed between adjacent two shoes into advance and retard oil chambers. The vane member rotates to an advanced angle side and to a retarded angle side relative to the housing by selectively supplying or exhausting hydraulic pressure in or from the advance oil chamber and the retard oil chamber. A most-advanced angle position and a most-retarded angle position are limited by the fact that one vane touches one shoe from a circumferential direction. Radius of curvature of one of both corners of a base part of the one shoe, which is a corner located at a side where the one vane does not touch, is set to be greater than those of corners of the other shoes.

A rotor includes a rotor core fixedly attached to a rotational shaft and having a plurality of hole portions arranged in the circumferential direction, a magnet inserted into a plurality of hole portions each, and a filling portion injected into the hole portion. The filling portion is injected into the hole portion from a gate facing a central part in the width direction of the magnet in the opening of the hole portion.
摘要:
Even if an internal combustion engine is stopped having a lock pin of a vane rotor kept disengaged from a lock recess, subsequent engine starting can instantly move the vane rotor to a desired angular position where the lock member an be engaged with the lock recess. The vane rotor has therein two passage control mechanisms each having a hydraulically actuated valve body. When the valve body is moved to a given position, retarding and advancing hydraulic holes become communicated to each other through an annular groove of the valve body. Due to this ON communication, retarding and advancing operation chambers become communicated, so that reciprocative swing movement of the vane rotor induced by an alternating torque produced at the starting of the engine is effectively made and thus the vane rotor can be quickly turned to the desired angular position for ease of engine starting.
