摘要:
A cable clamp of the present invention comprises a base having a fixing portion on the lower surface, a flat clamp rockingly connected to the base, and a means for locking a distal end of the flat clamp to the base engageably or disengageably. The cable clamp retains electric wires between the base and the flat clamp. The locking member comprises a plate-shaped protrusion provided on the flat clamp or the base and a retaining protrusion formed with the outer surface thereof. A resilient retaining member is protrudingly provided on the flat clamp opposite the plate-shaped protrusion or the base and has a hole for engaging with the retaining protrusion. An engaging member is protrudingly provided on the same surface with the resilient retaining member in parallel and engaging with an inner surface of the plate-shaped protrusion. Further, a notched portion formed with a distal end of the resilient retaining member faces the engaging member. Therefore, the cable clamp can easily carry out unlocking without any unlock levers and offers not only a simple but a secure locking mechanism.

A lift apparatus for lifting cigarette filter plugs which receives cigarette filter plugs fresh from a plug making machine and delivered by a lower horizontal conveyer and upwardly conveys the plugs while piled in multiple layers to an upper horizontal conveyer. The lift apparatus has a pair of vertical conveyers formed of flat belts and diverging as they extend upwardly. A pressurizing conveyer is provided outwardly of a bend in the conveying passage extending from the lower horizontal conveyer to the vertical conveyers. This pressurizing conveyer is rotatable at a greater speed than the vertical conveyers.

The cold-rolled steel sheets are characterized by containing 0.03-0.30 mass % carbon, up to 3.0 mass % (including 0 mass %) silicon, 0.1-5.0 mass % manganese, up to 0.1 mass % phosphorus, less than 0.01 mass % sulfur, up to 0.01 mass % nitrogen, and 0.01-1.00 mass % aluminum and having a structure which comprises tempered martensite in an amount of 50% or more (including 100%) in terms of areal proportion and in which the remainder is ferrite. The steel sheets are further characterized in that at least one of the following structural factors has been regulated: the proportions of cementite particles and of the ferrite grains in the tempered martensite and the dislocation density in all structures.
摘要:
A method of enhancing the efficacy of a monoclonal antibody preparation wherein antigens from patients are tested for their reactivity with the antibody. An amino acid sequence of an expressed protein is deuced from a nucleotide sequence determined by isolation and analysis of a target molecule gene in a biopsy from a patient. This is compared with the previously determined amino acid sequence recognized by the monoclonal antibody preparation in order to assess the fitness of patients for administration of the monoclonal antibody preparation.
