摘要:
A bias circuit including: a first current source which generates a first current; a second current source which generates a second current having a temperature-to-output current characteristic that an output current characteristic increases or decreases with a change in temperature to intersect with that of the first current; a first current-voltage conversion circuit which converts the first current to a first voltage; a second current-voltage conversion circuit which has an input terminal and converts a current inputted into the input terminal to a second voltage; a comparison circuit which compares the first voltage and the second voltage and generates a third current according to a result of the comparison; an addition unit which adds the third current to the second current and inputs a resulting current to the input terminal; and a voltage-current conversion circuit which converts the second voltage to a fourth current for bias.

A side face excluding the edge of a squeegee cleaner made of a plate-shaped urethane rubber is brought into pressure contact with a squeeze roller. Even for long-term use, a pressure contact surface of the squeegee cleaner does not break and long life of the squeegee cleaner is obtained and good cleaning performance is maintained and a liquid developing agent of a surface of the squeeze roller is surely removed.

摘要:
Thienodiazepine compounds of the formula ##STR1## wherein each symbol is as defined in the specification, their pharmaceutically acceptable salts, and pharmaceutical compositions containing said compound.Since the compounds possess excellent antagonistic actions on cholecystokinin and gastrin, and exhibit potent and durable suppressive actions on pancreatic enzyme secretion and gastric acid secretion, they are useful as medicaments acting on the central nervous system and the peripheral nervous system, as well as prophylactic and therapeutic medicines for pancreatic disorders and gastrointestinal ulcers. Furthermore, they are expected to exhibit anti-dementia actions based on their antagonistic actions on cholecystokinin, and are useful as an anti-dementia.
摘要:
A developing apparatus comprises a developing roll for carrying a nonmagentic toner thereon, and an elastic blade pressed against the outer circumferential surface of the developing roll to apply the toner thereto. The toner is applied to the surface of the developing roll by the elastic blade to form a thin layer of the toner on the surface of the developing roll. The thin layer is opposed to a photosensitive body to deposit the toner on a latent image on the photosensitive body. The developing roll has a surface which is opposite to the photosensitive body and the whole of which is roughened.

An ion flow modulator with high reliability used in a photocopying machine to obtain a high quality image. The ion flow modulator includes an insulating substrate, a common electrode formed on one major surface of the insulating substrate, a plurality of ion flow control electrodes formed on the other major surface of the insulating substrate, a photoconductive layer formed on the insulating substrate and connected to one end of each of the ion flow control electrodes, a first voltage application electrode formed on the insulating substrate and connected to the photoconductive layer, a resistance layer formed on the insulating substrate and connected to the other end of each of the ion flow control electrodes so as to interpose the ion flow control electrodes between the photoconductive layer and the resistance layer, a second voltage application electrode formed on the insulating substrate and connected to the resistance layer, and a DC power source for applying voltages having opposing polarities to the first and second voltage application electrodes. The ion flow passage holes are formed through the insulating substrate and the common electrode. A means is provided for generating ions to pass through the ion flow passage holes.
摘要:
A developing apparatus for developing an electrostatic image on an electrostatic image bearing member. The apparatus is provided with a container for storing toner which is a single component developer. A developing brush roller having fur on its peripheral surface transports the toner from the container and applies it to the electrostatic latent image. The developing brush roller is constructed of a core formed with elastic material and a fur formed on the peripheral surface of the core which contacts the surface of the electrostatic image bearing member.
