A cylinder block for an engine is formed of a cylinder block body and a lower block which are cast from aluminum alloy and are fastened together to support therebetween a crankshaft of the engine. The upper half of a bearing portion for supporting the crankshaft is provided in the cylinder block body and the lower half of the bearing portion is formed by a bearing cap cast in the lower block. A method of manufacturing the cylinder block includes the steps of casting the cylinder block body and the lower block with the bearing cap cast in the lower block, fastening together the cylinder block body and the lower block by bolts, performing primary stage finishing of the bearing portion with the cylinder block body and the lower block kept fastened together, releasing the lower block from the cylinder block body after the primary stage finishing of the bearing portion and permitting the lower block to deform under stress produced by shrinkage of aluminum alloy, fastening again the cylinder block body and the lower block together by the bolts, and performing final stage finishing of the bearing portion with the cylinder block body and the lower block kept fastened together.

A manufacturing method for a head-stack assembly. The method includes preparing a head-stack assembly. The method further includes placing a connection pad forming surface of a connector tab formed on an end of the trace so as to be positioned opposite to an edge of a circuit board; sliding an elastic component along a backside of the connection pad forming surface; and, stopping the elastic component on the backside and pressing the backside with the elastic component so as to press the connection pad forming surface against the edge. In addition, the method includes metal-joining the connector tab and a connection pad of the circuit board by applying heat to a connection pad of the connector tab and the connection pad on the circuit board while pressing the connection pad forming surface against the edge with the elastic component; and, removing the elastic component after the metal-joining.

Embodiments of the present invention provide a soldering method capable of satisfactorily melting a solder without damaging a workpiece be soldered. One embodiment of a soldering method removes component waves of predetermined wavelengths from a light beam emitted by a light source and melts a solder by irradiating the solder with a light beam obtained by removing the component waves of the predetermined wavelengths from the light beam emitted by the light source.

A battery pack rechargeable by a magnetic induction effect incorporates a secondary coil electromagnetically coupled to a primary coil of a battery charger and a secondary battery rechargeable by electric power induced to the secondary coil. The secondary battery is in a form of a thin battery having a larger width than a thickness, and two opposing surfaces of the secondary battery are composed of a first flat surface and a second flat surface. The secondary coil is in a form of a planar coil with a wire material being spirally coiled in the plane. In the battery pack, the secondary coil in the form of the planar coil is fixedly layered on the first flat surface of the thin battery.

In a manufacture of a probe for a scattering type near-field microscope, there is provided a method of coating, with a high reproducibility, uniform metal particles efficiently inducing a surface enhanced Raman scattering. It has been adapted such that, in the probe for the scattering type near-field microscope, one part or all of the probe due to an interaction of at least an evanescent field is coated by metal particles which don't mutually adhere and have a particle diameter of 10 nm or larger and 50 nm or smaller in radius of curvature.
