A toner used meets the requirement that the value determined by the equation 6/(d.sub.t .multidot..rho..sub.t .multidot.S), wherein d.sub.t is the volume average particle diameter of the toner, .rho..sub.t is the density of the toner, and Fs is the specific surface area of the toner, is in the range of 0.75 to 0.90, and the amount of electrification as measured by a magnet blow-off method is in the range of 10 to 40 .mu.C/g in terms of absolute value. A carrier used meets the requirement that the magnetic susceptibility is not less than 90 emu/g (at 1 kOe), the specific surface area is not less than 1000 cm.sup.2 /g to 1800 cm.sup.2 /g, the electric resistivity is 10.sup.6 to 10.sup.12 .OMEGA.cm, and the average particle diameter is 20 to 100 .mu.m.
摘要:
A coil type contactor comprising an electrically-conductive coil spring, each turn constituting the coil spring being inclined such that one end of a diameter of each turn occupies a lower position and the other end occupies an upper position. The turns are arranged such that axes passing through the centers of the respective turns are in parallel relation. Upper and lower ends of the coil spring serve as pressure receiving points, respectively, for achieving electrical connections. The turns are arranged such that they are partly short-circuited, or the turns are arranged proximate to each other so that the turns are short-circuited at an initial stage of compression.

This microporous film has an approximately uniform configuration in which the intervals between slender fibrils extend approximately two-dimensionally which are connected to each other between adjacent unstretched planar flat portions to define fine through-pores, and the distribution of pore size is sharp and the porosity is high. Accordingly, the microporous film excels in water filtration rate and selective separating capability and is suitable for use as filter membrane, separator membrane, gas exchange membrane, and a battery separator.

A flow rate sensor having an annular passage for enabling a flow of liquid therethrough and a movable member disposed in the annular passage. An intake passage is provided for supplying liquid to the annular passage and an outlet passage, disposed concentrically to the intake passage, enables the liquid to flow out of the annular passage about an outer periphery of the intake passage.
摘要:
A method and apparatus for developing an electrostatic image on an electrostatic image holding member by feeding toner particles thereto, in which a layer of the toner particles is formed on a toner carrying member, and the toner carrying member and the electrostatic image holding member are brought to a mutually closer position and maintained in such a range that the surface of a non-image section of the electrostatic image holding member and the surface of the toner particle layer on the toner carrying member may not be contacted with each other, but the surface of the toner particle layer is in contact with the surface of the image region of the electrostatic image holding member, whereby uniform development of the electrostatic image on the image holding member can be effected.
