A current detecting apparatus comprises a determining unit which determines whether the electric potential of a first node or a second node is in a predetermined range. When the condition that the electric potential is not in the predetermined range continues longer than the predetermined period of time, the determining signal indicating the damage occurrence is outputted. Accordingly, the damage of the constituting elements can exactly be determined with the relatively simple configuration in a short time.

A novel method for introduction of an exogenous substance or a physiologically active compound into cells is provided according to this invention. This method can realize introduction of an exogenous genetic substance or a physiologically active compound of large size with a large amount. Such substance is immobilized to beads of sphere fine particles having a particle size of 0.01 mm to 10 mm, and bio-active beads thus produced are introduced into cells. Bio-active beads comprising calcium alginate are particularly useful for the purpose of the present invention.

A concise method to promote growth of a plant useful for increase of food production. This invention provides a method to promote growth of a plant by administration of formic acid, an organic acid with a low molecular weight through avoidance of photo-oxidation damage. This invention also provides amino acid sequence of formate dehydrogenase and base sequence encoding the enzyme. The expression of the enzyme is induced by administration of formic acid and the enzyme is involved in metabolism of formic acid and its salts. Furthermore, this invention provides a method to promote growth of a plant by administration of methanol through avoidance of photo-oxidation damage.

A hot-dip galvanized steel sheet is produced by rough rolling a steel, finish rolling the rough rolled steel at a temperature of Ar3 point or more, coiling the finish rolled steel at a temperature of 700° C. or less, and hot-dip galvanizing the coiled steel at a pre-plating heating temperature of Ac1 to Ac3. A continuous hot-dip galvanizing operation is performed by soaking a pickled strip at a temperature of 750 to 850° C., cooling the soaked strip to a temperature range of 600° C. or less at a cooling rate of 1 to 50° C. per second, hot-dip galvanizing the cooled strip, and cooling the galvanized strip so that the residence time at 400 to 600° C. is within 200 seconds. The steel sheet has a structure consisting essentially of ferrite and martensite.

A method of manufacturing a spline shaft, comprising ironing a hollow stock by cold forging and forming splines in a desired portion of said hollow stock by cold forging by using its work harden state. This method makes it possible to reduce the weight of a product by using a hollow stock, and to prevent buckling of the material of the hollow stock during the formation of splines owing to work-hardening caused by the ironing. Further, a predetermined root strength can be ensured without requiring induction hardening. Accordingly, a reduction in weight is achieved, and the production speed and yield are improved.
摘要:
A motion vector detection circuit includes a registration determining switch which sets a first registration determination mode wherein at an initial field, correlation values are evaluated by a correlator on the basis of integrated color data of a specific detection block being stored in a representative color memory and integrated color data of twenty-five (25) detection blocks being stored in an integrated color memory. A comparison circuit compares the correlation values with a predetermined threshold value, and if a condition that the threshold value is larger than the correlation value is satisfied in each of eighty (80) percents or more detection blocks, the integrated color data stored in the representative color memory is registered as a representative color of an object, and otherwise, no registration is performed. In a second registration determination mode set by the registration determining switch, the correlator evaluates correlation values on the basis of the integrated color data of the specific detection block and integrated color data of four (4) detection block.
摘要:
A method of forming an internal spline shaft, comprising forming splines on an inner circumferential portion of a hollow stock by cold forging in such a way that a clearance "a" between an inner diameter of the hollow stock and an outer diameter of a tool guide portion, a difference "b" between a reduced diameter of a forming land and the inner diameter of the hollow stock, and a forming-land approach angle .theta. satisfy respectively specific relationships. By this method, products having internal long splines can be obtained in a high yield by cold forging method.
