Engagement claws on outer peripheries of a plurality of friction plates slidably engage the slits. Each slit includes a wide portion defined on an inner periphery of the cylindrical portion and into which the engagement claws are engaged, and a narrow portion defined on an outer periphery of the cylindrical portion with a width in a circumferential direction of the cylindrical portion being smaller than that of the wide portion. The wide and narrow portions are connected through a step facing a radially inward direction of the cylindrical portion. A draft for the wide portion during die-casting is less than a draft for the narrow portion, and a die-parting face in the die-casting is established on the side of the outer periphery of the cylindrical portion.

Abstract: A method of producing a Ni—Cu—Zn ferrite material comprises the steps of preparing a mixture of an iron compound powder having a specific surface area of about 8.5 m2/g or more, a nickel compound powder, copper compound powder and a zinc compound powder, the mixture having a specific surface area of about 8.0 m2/g or more; pre-calcining the mixture such that the pre-calcined mixture has a surface area of about 5.0 m2/g or more and a spinel crystal synthesizability within a range of about 80.5% to 98%; and milling the pre-calcined mixture to obtain a powder of a Ni—Cu—Zn ferrite material having a specific surface area of about 6.0 m2/g or more.

Abstract: A multiple-wound, three-phase, variable speed motor having N independent winding sets is driven by N inverters, each responding to 1/N of the torque and excitation current commands, and the torque current is limited as a function of N times the limiting current each inverter may tolerate, when all inverters are functioning. When M inverters fail, they are disconnected from the motor, the torque current is limited as function of N-M times the limiting current each inverter may tolerate. The remaining N-M inverters may each respond to 1/(N-M) of the torque and excitation commands. The excitation current may be maximized as (N-M) times the limiting current divided by the square root of two. The speed command may be predetermined by the integration over an acceleration interval, of the maximum acceleration achievable with torque available from those of the inverters which have not failed, in view of the inverters' current limits.

Abstract: In an electrophotographic copying apparatus, component units are disposed in a vertical arrangement so that the electrophotographic copying apparatus can be made more compact, lighter in weight and shorter in copying time. An image processing and conveyance unit has a sheet feeder unit, an image processing unit and a fixing-and-discharge section placed generally vertically in this order from below. A developing unit of an image processing unit is retained by a unit retaining portion formed into a generally U shaped cross section and erected on both sides of one end of a base, and by a resin frame having pillar portions integrally formed at the other end. An exposure optical unit is fitted to an upper end portion of the resin frame, and the image processing and conveyance unit is so arranged that its top portion is located in a place out of the region of scanning by a reflecting apparatus of the exposure optical unit.

Abstract: A vent hole 3 for exhausting a gas component generated from a melted resin is provided at a heating cylinder. A gas staying chamber is formed at the interior by covering the upper portion of the vent hole, and there are provided a vent hole cover having a gas exhaust port at its upper portion and an inert gas supply unit for supplying an inert gas to the inside of the vent hole cover. Thereby the inert gas stays in the gas staying chamber, and a gas shielding layer for shielding the vent hole from the atmospheric air is formed.

Abstract: An apparatus for exposure correction is provided for use with a camera of automatic exposure control type. An amount of exposure which is determined on the basis of an output from photometric means is shifted by a given correction value toward overexposure or underexposure in response to the operation of a manual operating member. The correction value can be varied either automatically or manually. The correction value can be changed by automatically reading information given on a film or a film container and representing a film latitude, by manually supplying a film latitude value, or by utilizing information representing a film speed which has a correlation with a film latitude. In this manner, a photograph having an improved gradation can be obtained by effectively utilizing a film latitude.
