The semiconductor device having the structure which laminated the chip in many stages is made thin. A reforming area is formed by irradiating a laser beam, where a condensing point is put together with the inside of the semiconductor substrate of a semiconductor wafer. Then, after applying the binding material of liquid state to the back surface of a semiconductor wafer by a spin coating method, this is dried and a solid-like adhesive layer is formed. Then, a semiconductor wafer is divided into each semiconductor chip by making the above-mentioned reforming area into a division origin. By pasting up this semiconductor chip on the main surface of an other semiconductor chip by the adhesive layer of the back surface, the semiconductor device having the structure for which the semiconductor chip was laminated by many stages is manufactured.

A polymer composition that contains a thermotropic liquid crystalline polymer, fibrous filler (e.g., glass fibers), and a flow aid is provided. The flow aid is in the form of an aromatic amide oligomer which, due to its unique nature and properties, has the ability to dramatically reduce melt viscosity with only a minimal degree of blending with the polymer. More particularly, the fibrous filler is supplied to an extruder in conjunction with the polymer and/or at a location downstream thereof so that the polymer is still in a solid or solid-like state when it initially contacts the filler. In this manner, the fibrous filler and polymer are allowed to mix together while the composition still has a relatively high melt viscosity, which helps to uniformly disperse the fibrous filler within the polymer matrix. After a certain period of time, the aromatic amide oligomer is then supplied to the extruder at a location downstream from the fibrous filler to reduce the melt viscosity of the composition.

The hazard caused by debris flow provides scientific basis for the planning and design of earthquake prevention and disaster reduction.

A self-regulating on-demand gas generator. Generation of gas produced from a reaction is selectively, variably, and spontaneously controlled. A variable volume liquid chamber in communication with the pressure pot allows the volume of liquid reactant in the pressure pot to be varied. The amount of product gas generated in the pressure pot depends on the degree of contact between the solid-like reactant and the liquid reactant. The pressure of the product gas regulates the level of liquid in the pressure pot and thereby regulates the degree of contact between the solid-like reactant and the liquid reactant. A sealed gas chamber sharing a flexible diaphragm with the liquid chamber controls the expandability of the liquid chamber. Manipulating the pressure in the sealed gas chamber or the volume of the liquid reactant affects the pressure at which contact by the reactants will be initiated or terminated and thereby provides the ability to control the reaction.
