A lever is connected to the frame, with the lever being elastically deformable such that a first part of the lever is movable relative to a second part of the lever and relative to the frame, and the lever protruding from the frame. A coupling member is configured to transmit a rotational force to the developing roller, the coupling member being rotatable about a rotational axis thereof, and the coupling member being movable relative to the frame in a direction of its rotational axis. When the cartridge is oriented with the lever and the electrode portion at a bottom portion of the cartridge, the lever protrudes downward from the frame.

Abstract: At the time for forming an internal gear from a raw material 2 of an internal gear, first, the raw material 2 is externally inserted onto a forming die 3 and fixed to the forming die 3 through a pressing die 4. Next, a forming roll 5 is moved in a direction as indicated by an arrow B of FIG. 6 while rotating the forming die 3. By this, the inner peripheral surface of the raw material 3 is pressed against an outer gear part 3b formed on the outer peripheral surface of the forming die 3 so that an internal gear part 1c is formed on the inner peripheral surface of the raw material 2.

A solution containing hydrogencarbonate ion, bromide ion, carbonic acid ion, and, if necessary, fluoride ion, and being adjusted to a pH of 7.0 to 11.5 can be used as a substitute for a cutting oil. A water-soluble cutting fluid further including additives such as rust-preventive agents and the like can be also used as a substitute for conventional cutting oil.

Abstract: A method for easily decomposing viscous, solidified spilled fuel oil or crude oil containing sea water and other disposal inhibiting substances. Titanium dioxide particles are added to viscous spilled fuel oil recovered in drums in a weight ratio of at least 0.2 to 1 times. Fuel oil is specifically adsorbed by the adsorbent and the mixture can be suspended in water. The suspension is filtered by a coarse filter to remove substances interfering with disposal by the oil. This filtrate is passed through a high performance filter (of sufficiently fine mesh to retain the adsorbent) so that the adsorbent is recovered, and sea water and other substances are discarded.

Abstract: In a method of coextracting neptunium and plutonium, a nitric acid solution containing a mixture of neptunium and plutonium is oxidized by irradiation of ultraviolet light. As a result, different valences of neptunium are adjusted all into the valence 6, which can remain in water, and in the meantime, valences of plutonium are adjusted into the valence 4 or 6, which can be extracted in the organic phase. It is therefore possible to coextract neptunium and plutonium without difficulty. The coextracted neptunium and plutonium can be used in forming mixed fuel by blending at least a portion of at least one of neptunium and plutonium which neptunium and plutonium have been formed by separating a nitric acid solution containing neptunium and plutonium by exposing the solution and a reducing agent to ultraviolet radiation to adjust the valences, and extracting the solution using an organic phase to extract plutonium from the solution into the organic phase.

Abstract: Fission noble metals contained in an insoluble residue and/or a high-level radioactive liquid waste generated in the step of reprocessing spent nuclear fuels are dissolved in nitric acid to prepare a palladium-containing nitric acid solution, which is then brought into liquid-liquid contact with an extracting solvent containing a dialkyl sulfide in which each alkyl group has 4 to 10 carbon atoms as an extractant to extract the palladium component into the extracting solvent. The palladium-containing extracting solvent is brought into liquid-liquid contact with an aqueous thio compound solution or aqueous ammonia solution to strip the palladium component into the aqueous solution. A borohydride compound in added to the palladium-containing aqueous solution to precipitate palladium from this solution by reduction, and metallic palladium is recovered by separating the precipitate from the aqueous solution.

Abstract: Particles contained in a suspension are separated in accordance with their magnetic susceptibility and based on the variation in flow velocity of suspension. In order to achieve this magnetic separation, a pair of wall plates having at least one flat surface in which a plurality of ferromagnetic narrow wires are buried in parallel are positioned in parallel to each other with a small distance therebetween so that the flat surfaces are opposed to each other to form a channel. The suspension flows in a laminar state with different flow velocities through the channel in the longitudinal direction of the ferromagnetic wires. A magnetic field is externally applied to the channel in the direction perpendicular both to the flow direction and the wall plates. Particles are separated in accordance with their magnetic susceptibility and based on variation in flow velocity which interacts with the magnetic susceptibility.

Abstract: A power-on reset system comprises one-shot pulse generator for generating a one-shot pulse signal in response to a change in the power supply potential, a flip-flop to be set to operate by a one shot pulse signal and a timer to be activated by an output signal of said flip-flop operating as an enable signal for timing a given period of time. An output signal of said timer operates to reset the flip-flop so that the output of said flip-flop is utilized as a system reset signal. The timer includes an oscillator and a counter for counting oscillation signals. A voltage step-up means has an input responsive to the oscillation signals. With such an arrangement, the overall surface area of an LSI incorporating the system is minimized and a sufficiently long reset period is ensured for it.
