Abstract: This invention can considerably improve the adhesion property of a film to a matrix surface of a silicon steel sheet by forming an interface layer such as nitride-oxide layer of one or more selected from Fe, Si, Al and B or an extremely thin base film formed by finely dispersing nitride-oxide of one or more selected from Fe, Si, Al and B in the same film components as a tension insulating film at an interface between the matrix surface and the tension insulating film, or further by immersing in an aqueous solution of a chloride mainly composed of SiCl4 to dissolve the matrix surface or conducting a smoothening treatment or a pickling treatment with an aqueous solution containing SiCl4 prior to the formation of the interface layer, and hence ultra-low core loss grain oriented silicon steel sheets having a core loss considerably superior to that of the conventional one and an excellent magnetostriction property can be obtained very cheaply and in a higher productivity.

Abstract: A start-up circuit for supplying current to an analog circuit. The start-up circuit comprises a capacitor connected to a current mirror. A power-up signal input to the start-up circuit causes the capacitor to discharge to the current mirror thereby causing the current mirror to provide a current to the analog circuit.

Abstract: A motorization system for a merchandise cart having at least two wheels including a direct current electric power storage unit; a power supply controller connected to the power storage unit; and two electric motors connected in series and connected to the controller, with each of the motors being operatively associated with one of the wheels and each motor having a nominal operating voltage equal to half the nominal output voltage of the power storage unit.
Abstract: Methods and adhesive labels useful in marking products or documents by applying these to substrates. A mark such as a barcode, photograph or characters are formed directly on the substrate and the adhesive label is applied over it. The adhesive label includes a concealing film layer which is transparent to a first wavelength outside the visible region, a diffractive optical mark with a transparent reflective layer and an adhesive layer. The first wavelength may be infrared allowing the underlying mark to be read by an IR laser. The adhesive labels are formed as to allow them to be continuously separated from a temporary detachment layer, thereby exposing the adhesive layer, and affixed to the document.
