摘要:
A cooling water passage structure of internal combustion engines is provided which can contribute to a scale-down of the external form of the engine and also can prevent deformation of the cylinder bores. The cooling water passage structure comprises a water jacket for the flow of cooling water provided on the peripheries of a plurality of cylinder bores; and a lateral suction passage 9a, 9b integrally formed with a side wall of a cylinder block 2 having bolt holes formed for fastening a cylinder head 3. The lateral suction passage runs through by the cylinder bores at a height in the vicinity of the water jacket bottom and is arranged on the outside of, and perpendicular to the bolt holes. On the rear surface of the cylinder head 3 is mounted a water passage block 15 and on the front end part of the cylinder block 2 is provided a water pump housing 10.

The present invention concerns an exchange control method, wherein an old host exchange accommodating a remote switch unit or subscribers is adapted to be accommodated in a new host exchange, and its object is to allow call processing control to be performed by the new host exchange while making effective use of the resources of the old host exchange including the remote switch unit. The new host exchange and the old host exchange are connected in an interoffice configuration by a signaling link, and each exchange includes an emulation processor; the old host exchange and the new host exchange perform message editing and exchange between the respective emulation processors, and exchange control is performed in such a manner that when there occurs data or a request for basic control that is normally processed at the old host exchange, the data or request is transferred to the new host exchange, and the new host exchange processes the data or request and sends a notification to the old host exchange.

To provide a conductive paste that exhibits a high thermal conductivity (a low thermal resistance) after adhesion and hardening and that enables an adhesive layer to be formed thin and to provide an electronic part that has an excellent radiating capability and that enables the thickness of films to be reduced. A conductive paste containing conductive particles, a hardenable resin, and a solvent has mixed therein fine spherical conductive particles such as Ag particles, the particle size is on the order of 0.05 to 1 &mgr;m, smaller than the first conductive particles. This conductive paste is used to mount an electronic part such as a semiconductor chip in producing a semiconductor package.

In a water-cooled engine cylinder block, a lower end of a water jacket outer wall and a cylinder wall are joined by a water jacket base wall, and coolant is led into a space formed by the cylinder wall, water jacket base wall and water jacket outer wall. A bend part having a crank shape cross-section is formed in the water jacket base wall. As a result, the rigidity of the water jacket base wall decreases so that transmission of the axial tension of the head bolt to the cylinder wall is suppressed, and deformation of the cylinder wall is suppressed.

A liquid discharge apparatus includes a conveyer, a liquid discharge head, and a supporter. The conveyer is configured to convey a recording medium in a conveying direction parallel to a reference line. The liquid discharge head includes a discharge surface that includes discharge portions and a non-discharge portion. The non-discharge portion is disposed between two adjoining discharge portions and extends to converge on the reference line from an upstream side toward a downstream side in the conveying direction. The supporter includes a projection that includes a top portion facing the non-discharge portion and extending along the non-discharge portion. The top portion is configured to support the recording medium. The top portion is sloped, such that a distance between the top portion and the discharge surface increases from the upstream side toward the downstream side in the conveying direction.
