[Problem] Because the knife edge of medical knives such as straight knives manufactured with austenite stainless steel is thin and sharp, there is the problem that the knife edge bends too easily when making incisions in the cornea, sclera, etc. during ophthalmologic surgery. The invention provides a medical knife capable of increasing the strength of the thin, sharp knife edge and preventing the reduction of sharpness. [Solution] This medical knife has a flat cutting part and an inclined surface formed along the border of said cutting part. By electrolytic polishing or chemical polishing of the inclined surface, a convexly curved cutting edge is formed on at least the edge of the inclined surface of the knife. The knife edge has a rounded configuration. The knife edge being rounded increases the thickness of the knife edge, increases the strength thereof and hinders bending.

The invention relates to a stirred tank reactor for gas-liquid mass transfer in a slurry. The reactor includes a reactor tank (1) having a first volume (V1), a drive shaft (2) that extends vertically in the reactor tank, a motor (3) for rotating the drive shaft (2), a main impeller (4) which is a downward pumping axial flow impeller attached to the drive shaft (2) to create a main flow pattern in the reactor tank, and a gas inlet (5) arranged to supply gas into the reactor tank (1) to be dispersed to the liquid. The reactor includes a mechanical gas sparging apparatus (6) comprising a dispersion chamber (7) having a second volume (V2) which is substantially smaller than the first volume (V1) of the reactor tank (1), the dispersion chamber being arranged coaxial with the drive shaft (2), and the gas inlet (5) being arranged to feed gas into the dispersion chamber (7), and mixing means (8, 9, 10, 11, 12) arranged within the dispersion chamber (7) for mixing the gas into liquid by dispersing the gas to fine bubbles before the bubbles enter the main flow pattern. The mixing power per unit volume inside the dispersion chamber (7) is significantly larger than the mixing power elsewhere in the reactor.

Disclosed are a low-cost radio wave-transmitting decorative film which has excellent stretch moldability, radio wave transmissibility, and mirror-like metallic gloss that does not easily disappear, and a decorative member employing the radio wave-transmitting decorative film. Specifically disclosed are a decorative film which includes a first polymer film, a second polymer film, and a light-reflecting layer which is arranged between the polymer films and formed by the physical vapor deposition of an alloy of silicon and a metal, and a decorative member in which the decorative film is provided on the surface of a base.

The present invention relates to the field of linear actuators, and in particular, to a high-efficiency high-thrust electric linear actuator for a solar panel. Compared with a conventional electric linear actuator, in the electric linear actuator for a solar panel of the present invention, a drive nut on a screw uses a copper alloy nut. The copper alloy nut used in the present invention greatly improves the strength, toughness, and fatigue-resistance performance and has high hardness and high tensile strength. The copper alloy nut and the corresponding screw are used in combination to bear higher pressure and do not fracture easily. Therefore, a small-structure high-thrust electric linear actuator can be realized. An electric linear actuator having a smaller volume is used to support the solar panel, so that small space is occupied, and transportation and use become more convenient.

A method of manufacturing a straight knife includes pressing one end of a rounded austenitic stainless steel rod flat and press-cutting away an excess portion of the flattened end to form a blade; grinding the blade to form a slanted surface and an edge along at least a portion of the periphery of the blade; removing burrs along the slanted surface and the edge of the blade by electrolytic polishing or chemical polishing; and continuing with the electrolytic polishing or chemical polishing to form, at a tip of the slanted surface, a cutting portion of the blade having a cross-sectional shape defined by convex curves.

A covering method including: preparing a mixture containing insulative material and a solvent; applying the mixture over a defective portion; and covering the defective portion with the insulative material by causing the solvent to evaporate from the mixture. In the covering method, the solvent has a boiling point no lower than 178 degrees Celsius, and in the mixture, a weight ratio percentage of the insulative material to the solvent is no lower than 10%. Thus, the defective portion, which may result in a dark spot, can be efficiently covered with insulative material while ensuring that a non-light-emission area that is formed accordingly has the smallest-necessary size and that sufficient insulation is achieved.
