An adhesion-reinforcing composition for an epoxy resin adhesive which comprises a copolymer resin particle having been ion-crosslinked with a univalent or divalent metal cation, which particle is comprised of (i) a core ingredient composed of a polymer comprising diene monomer units and optional crosslinking monomer units and having a glass transition temperature not higher than -30.degree. C. and (ii) a shell ingredient composed of a copolymer having a glass transition temperature of at least 70.degree. C. and comprising acrylate or methacrylate monomer units and 0.01-20 wt. parts, per 100 wt. parts of the shell ingredient, of units of a radically polymerizable unsaturated carboxylic acid monomer having a carboxyl group and 3-8 carbon atoms; the core/shell weight ratio being 5/1-1/4. A composition comprising 100 wt. parts of an epoxy resin, 15-60 wt. parts of the adhesion-reinforcing composition, and 3-30 wt, parts of a heat-activation type curing agent is useful as a structural adhesive for automobile parts.

A thin type image display device for displaying an image by emitting light from a fluorescer with irradiation of electron beams thereto. The device has a cathode panel between a front panel and a back panel in such a manner that a space is existent between the cathode panel and the back panel, wherein through holes for diffusion of getters are formed in the cathode panel to maintain the image quality at the center of a display screen, or the cathode panel is supported by getters to maintain a required pressure, hence attaining a higher image quality even on a large-sized display screen. A gate electrode may be composed of a getter material.

摘要:
A flat thermionic cathode is provided with a substrate having at least one main heating element thereon to produce at least one substantially localized area of heat and a sub-heating element to substantially define a heating area, the localized area being produced within the heating area. A cathode element including electron emissive material is disposed at the localized area. While the localized area tends to produce a temperature gradient directed from the localized area toward the perimeter of the substrate so as to create thermal stress in the substrate along the perimeter thereof, the sub-heating element reduces this temperature gradient and, consequently, the thermal stress.

摘要:
A hydraulic working machine has an assist electric motor connected to an engine and a hydraulic pump. The emissions of air pollutants in the exhaust gas from the engine are minimized regardless of fluctuations in the load torque of the hydraulic pump. A specific revolution speed suitable for reducing the emissions of air pollutants is stored, and an engine is controlled using the specific revolution speed as a target revolution speed. The absorption torque of a hydraulic pump is subjected to high-pass filtering whereby a high-frequency component devoid of a trend component is obtained. Target assist torque is computed from the high-frequency component, and the assist electric motor is subjected to power running/generation control accordingly. A specific output torque range suitable for reducing the emissions of air pollutants is stored, and the target assist torque is corrected so that the trend component does not exceed the specific output torque range.
