摘要:
An image forming apparatus includes a developer that develops a latent image to form an image, a separation unit that separates image information of a job image by color upon writing a latent image of the job image, a comparison unit that compares the image information by color separated by the separation unit with a threshold value previously set with respect to an image concentration, and a driving condition determination unit that determines a driving condition of the developer using a result of comparison by the comparison unit.
摘要:
The invention provides a high voltage MOS transistor having a high source/drain breakdown voltage of about 300V and a low on-resistance. An N-type body layer is formed extending from a source layer side to under a gate electrode. A P-type second drift layer is formed in an epitaxial semiconductor layer by being diffused deeper than a first drift layer, extending from under the first drift layer to under the gate electrode and forming a PN junction with the body layer under the gate electrode. A surface of the body layer between this second drift layer and the source layer serves as a channel region. The first drift layer is formed at a distance from a left end of the gate electrode where electric field concentration easily occurs.
摘要:
In an image forming apparatus, an area applied with a lubricant, i.e., an area of a lubricant layer having a uniform thickness, is obtained by spreading the lubricant by a lubricant smoothing blade. The area applied with a lubricant covers an area cleaned by a cleaning blade, i.e., a contact portion of the cleaning blade with a photoconductor.
摘要:
A process cartridge including an image bearing member; a lubricant applicator, which includes a lubricant application member configured to apply a solid lubricant to the surface of the image bearing member; and a smoothing member configured to smooth the applied solid lubricant, and at least one of a charging device, a developing device and a cleaning device, wherein the amount of the solid lubricant present on a portion of surface of the image bearing member, which is located between the lubricant application member and the smoothing blade, is from 0.11 to 1.2 mg/m2. The smoothing member is preferably a blade having a JIS-A hardness of not less than 79°. The process cartridge is preferably assembled by a method including setting the lubricant smoothing member, the lubricant and the lubricant application member to a housing of the process cartridge; and then setting the image bearing member to the housing.

摘要:
A transferring apparatus is provided between a plurality of carrying apparatuses, each carrying apparatus comprising support means for supporting carried products Wf, guide means for controlling the moving direction of the support means, the guide means being provided along processing apparatuses for processing the carried products Wf, and moving means for moving the support means along the guide means. The transferring apparatus includes synchronization control means for synchronizing the moving means of the one carrying apparatus with the moving means of the other carrying apparatus; and at least one hand-over means for receiving the carried products Wf from the support means of the one carrying apparatus and handing over the carried products Wf to the support means of the other carrying apparatus.
摘要:
A contaminated Group III metal hydrocarbon is purified by providing an adduct of Group III metal hydrocarbon with a Lewis base in a solvent having a boiling point which is up to 200° C., but at least 30° C. higher than the boiling point of the Group III metal hydrocarbon, separating the solvent from the adduct, and heating the adduct for thermal dissociation, thereby releasing the Group III metal hydrocarbon in high purity form.
摘要:
An image forming apparatus includes a toner forced discharge treatment for executing a toner discharge mode in which toner inside a developing device is forcedly consumed, and a toner discharge judgment treatment capable of judging necessity of execution of the toner discharge mode based on a decision as to whether or not a toner state inside the developing device is in a state of leading to an image quality defect. Further, the apparatus includes a toner forced supply treatment for executing a toner supply mode in which new toner is supplied from a toner replenishment device to the developing device in addition to execution of the toner discharge mode.
摘要:
A method of purifying an organometallic compound comprising distilling the organometallic compound for purification while blowing an inert gas through a vapor of the organopolysiloxane, thereby removing from the organometallic compound an impurity having a higher vapor pressure than the organometallic compound.
摘要:
Trialkylgallium is prepared by reacting a gallium halide or alkyl gallium with trialkylaluminum in a solvent having a boiling point which is at least 10° C. higher than the boiling point of the trialkylgallium, such as mesitylene or o-dichlorobenzene. High purity alkyl gallium is obtained in high yields.
