摘要:
A method of manufacturing a cylinder block using a die apparatus wherein a columnar hole includes a bore in the cylinder block. The method includes the steps of abutting first and second split cores against an upper surface of a distal end core, the upper surface being located opposite the inner core, and introducing a molten metal into a cavity. An inner core is withdrawn to move the first and second split cores toward an axis. The first and second split cores are released from a formed product made of solidified molten metal. The split cores are removed from the formed product to form the bore, and an inner surface of the bore is cut.

In forming a thin film of silver mirror on a surface of an object to be coated, a silver mirror reaction-treating solution including three solutions: an ammoniacal silver salt aqueous solution (I), an aqueous solution of caustic soda (IIa) and an aqueous solution of a carbohydrate-based reducing agent (IIb) such as glucose (fructose) are used. Immediately after the caustic soda aqueous solution (IIa) and the reducing agent aqueous solution (IIb) are mixed, the resulting mixed liquid and the ammoniacal silver salt aqueous solution (I) are independently and simultaneously sprayed onto the object. Alternatively, the mixed liquid (II) and the ammoniacal silver salt aqueous solution (I) are mixed together immediately upstream of a spraying nozzle, and the mixed liquid (III) is sprayed onto the object. Thereby, a thin film of silver mirror is formed in a thickness of around 0.01 to 0.03 μm, for example, through depositing silver by a silver mirror reaction.

An absorbent article comprises a non-woven fabric sheet to come in contact with the skin of a user and an absorbent layer provided under said non-woven fabric sheet, said non-woven fabric sheet comprising polyester oligomer fibers having a hydrophilic group at least on the surface side to come into contact with the skin of a user so that said surface gets hydrophilic.
摘要:
A pair of metallic thin films are attached to opposite surfaces of a heat resistive thin film, and the heat flux through the heat resistive thin film is determined by measuring the temperature gradient therein while using the metallic thin films as resistance thermometer elements.
摘要:
A tampon applicator comprises an outer cylinder containing an absorber and first and second inner cylinders for pushing out the absorber, wherein the first inner cylinder is fitted slidably into the outer cylinder, the second inner cylinder is fitted slidably into the first inner cylinder, and the second inner cylinder is provided on the outer surface thereof with a projection(s) having means for significantly changing the size thereof in the radial direction, which projection(s) is(are) kept in the first inner cylinder before use but serve to transmit a pushing-out pressure to the first inner cylinder at the time of the application.
