摘要:
The present invention provides a data path circuit layout design method capable of generating a mask layout which satisfies timing specifications and given contour conditions, and which is reduced in circuit area. There are prepared function macros in each of which there is defined an expansion, according to the parameters, to a circuit comprising a plurality of schematic leaf cells. For a data path circuit of which function blocks are described by function macros, the placement of the function blocks is optimized by a function macro placement process. By a function macro expansion process, the function macros describing the function blocks are expanded and connection information on the schematic leaf cell level are prepared. By a detail placement and routing process, the schematic leaf cells are replaced with the corresponding layout leaf cells and the layout leaf cells are wired to one another, thereby to generate a mask layout of the data path circuit.

A slider for slide fasteners comprises a slider body having a pair of upper and lower wings connected at one end by a neck portion to define a guide channel, a pull tab having a pintle provided at its one end and an attaching lug or lugs provided on the upper surface of the upper wing for pivotally connecting the pintle of the pull tab to the slider body. The upper wing has a land provided on the upper surface of the upper wing and disposed around the attaching lug or lugs. Correspondingly, the pull tab has a recessed surface on each side and adjacent to the pintle for receiving the land when the pull tab rests flat on the upper surface of the upper wing.

An electrophotographic copying apparatus includes a main body, a developing system, removably mounted on the main body, provided with a developing device having the developing sleeve holding a carrier on the outer surface, and a toner cartridge having a toner supply roller which confronts the developing sleeve. A voltage-adjusting device adjusts the bias voltage to be supplied respectively to the developing sleeve and the toner supply roller depending on a toner color so as to generate a predetermined electric potential between the developing sleeve and the toner supply roller. The voltage adjusting device adjusts the bias voltage difference between the developing sleeve and the toner supply roller according to a saturation charge amount which is different depending on the toner color.

A developing device includes a developing sleeve provided rotatably at a side of an electrostatic latent image support member, a supply member for supplying developer to the developing sleeve, a bristle height regulating member which confronts an upper portion of the developing sleeve so as to adjust an amount of the developer transported to a developing region and a plurality of magnets provided in the developing sleeve. The magnetic poles of the magnets not only extend in an axial direction of the developing sleeve but are arranged in a circumferential direction of the developing sleeve. The magnetic poles include a weak magnetic pole disposed adjacent to the upper portion of the developing sleeve and two strong magnetic poles between which the weak magnetic pole is interposed. The strong magnetic poles have a polarity different from that of the weak magnetic pole.
