摘要:
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.

A developing apparatus includes a developing roller confronting an image support member for generating an electrostatic latent image on its surface, an accommodating tank for accommodating developing material therein, and a supply roller disposed to confront the developing roller so as to supply the developing material accommodated within the accommodating tank onto the developing roller, and is characterized in that a developing material supply width of the supply roller is smaller than the effective developing width of the developing sleeve.

A developing device includes a developing sleeve which is provided with a plurality of magnets so as to transport a two-component developer composed of toner and carrier to a developing region where the developing sleeve and a member bearing an electrostatic latent image confront each other, a toner reservoir, a toner supply roller for supplying the toner to the developing sleeve, which is disposed at an end portion of the toner reservoir so as to be brought into contact with the toner in the toner reservoir, a rotary member which is rotatably provided in the toner reservoir so as to be rotated in contact with the toner supply roller and a charge erasing member for erasing electric charge of electrically charged toner transported to the toner reservoir by the toner supply roller.

A photosensitive member which comprises a photoconductive layer and an insulating layer located on the photoconductive layer, the photoconductive layer including amorphous silicon and the insulating layer including amorphous silicon, carbon, oxygen and fluorine. The photoconductive layer has a higher resistivity than the photosensitive member. A barrier layer may be located beneath the photoconductive layer, the barrier layer including either amorphous silicon, oxygen and a Group III impurity or amorphous silicon, carbon and oxygen.

An apparatus for measuring the ratio of alcohol contained in mixed fuel which flows through a fuel pipe to the engine. The fuel pipe is made of a high frequency signal permeable material such as rubber, teflon or nylon, for example. A microwave chamber is provided outside the fuel pipe, enclosing a part of the fuel pipe. The microwave chamber comprises a pair of wave guides opposed to each other with the fuel pipe interposed between them. One of the wave guides is provided with an antenna section for transmitting microwaves received from a microwave generator. The other wave guide is provided with a receiving antenna section for receiving the microwaves permeating through the fuel pipe through which the mixed fuel is flowing. The microwaves passing through the fuel pipe are attenuated according to the amount of alcohol in the fuel. The microwaves received by the antenna section are detected by a detector and converted to DC voltage signals which correspond to the strengths of the microwaves received and thus the amount of alcohol in the fuel.

A diesel smoke meter which uses micro-waves to detect the density of black smoke contained in the exhaust gas discharged from the diesel engine through an exhaust pipe. A micro-wave transmitting device is coupled to the exhaust pipe and transmits micro-waves into the exhaust pipe. Micro-waves transiting the exhaust pipe are attenuated by the black smoke in the exhaust gas. A micro-wave receiving device receives the attenuated micro-waves and provides a received signal which varies in accordance with the signal level of the attenuated micro-waves. A measuring device receives the received signal and provides an output indicative of the density of black smoke in the exhaust gas.

A herbicidal composition comprising a herbicidal amount of an active compound selected from the group consisting of acid addition salts of higher alkyl esters of amino acids, acid addition salts of N-lower alkyl substitution products of said esters and quaternary ammonium salts of N-lower alkyl substitution products of said esters, and a diluent or carrier, and a method for controlling weeds using said herbicidal composition.

An automatic telephone answering device includes a diode bridge rectifier having its input terminals connected across a pair of telephone lines through a first switch, and its output terminals connected across a relay coil through a voltage controlled impedance, such as a Zener diode. A relatively high frequency, high voltage call signal is rectified by the bridge and breaks down the diode to energize the relay coil. This closes a relay switch to actuate a control circuit, whose outputs a) actuate a tape recorder unit to play back a prerecorded message to the caller, and b) simultaneously transfer the first switch to connect the tape recorder unit across the telephone lines through a line transformer. The breakdown voltage of the Zener diode is selected to be above the voltage level produced by sound (conversation) signals and busy tone signals, whereby the device presents a high impedance to such signals and is not actuated thereby.

A vibration damping control device that controls driving power of a vehicle to suppress pitch vibration or bounce vibration includes: a vibration damping control unit that controls a driving torque of an engine so as to suppress the amplitude of the pitch vibration or bounce vibration on the basis of a wheel torque generated at a contact portion between a wheel of the vehicle and a road surface; and a compensating component regulating unit that varies the magnitude of a compensating component, which is calculated by a vibration damping control unit and which compensates the wheel torque for vibration damping control, on the basis of a change of characteristic, such as a wear state quantity of a movable portion of a throttle valve of the engine.
