An image forming apparatus and method in which a controller is capable of executing image processing of its own are disclosed. The controller has an RF unit for processing image information, a halftone image processor, a density corrector and a patch generator. The engine includes a modulator corresponding to the RF unit, a halftone image processor different from that of the controller, a density controller, modulator and patch generator corresponding to the halftone processor of the engine, a sensor for sensing the density of formed patches, and a control unit for controlling the density of an image on the basis of a signal from the sensor. The engine sends the controller a signal relating to density control.

A surface of a conductive member such as a gate electrode provided with a silicon layer is roughened. The roughened silicon layer is silicified so that its width is substantially increased, whereby phase transition of the silicide layer is simplified. Thus, the resistance of the refined silicide layer is reduced due to the simplified phase transition.

An image reading apparatus for reading images on films of different sizes and outputting read image data includes a film sensor for sensing the dimension of at least one side of each film and a control module for operating the apparatus so that at least one of the reading process and outputting process is performed under a parameter setting set beforehand in accordance with a signal from the film sensor. When a reading start instruction is issued from a control panel, a film width detecting circuit performs film sensing, thereby determining the film width of each film. Based on the film width, reading parameter values such as a pixel pitch, a density range, and a data transfer destination are selected from among those that are beforehand set through the control panel. Table update is made for a density linear conversion table according to the film width and an interpolation coefficient according to the pixel pitch. Each film is read through a halogen driving circuit and an actuator driving circuit, and the image data is output through an image data reading circuit.

An image forming system adopting a dual-component inversion developing system for forming on an image carrier a toner patch image used for detecting an image concentration and controlling an image forming condition such as toner concentration based on the concentration of the toner patch image. The image forming system includes a charge unit for uniformly charging a surface of the image carrier, a developing magnet roll supplied with a developing bias, and a patch forming unit for selecting voltage application conditions to the charge unit and the developing magnet roll so as to reverse the bias potential relationship between the developing magnet roll and a charge potential of the image carrier and forming a first toner patch image at a contrast potential between the charge potential of the image carrier and the bias potential.

A brake force control apparatus performs both a brake assist control and an antilock brake control without interference therebetween. A master cylinder generates a brake fluid pressure corresponding to a magnitude of a brake operation. A pump has an inlet port and an outlet port, the inlet port being communicable with the master cylinder. An inlet control valve controls communication between the master cylinder and the inlet port of the pump. A wheel cylinder is communicable with each of the master cylinder and the outlet port of the pump. A supplementary reservoir is communicable with each of the wheel cylinder and the inlet port of the pump. The brake assist control is performed, when the emergency brake operation is performed by the driver, by opening the inlet control valve and actuating the pump. The antilock brake control is performed by controlling communication between said wheel cylinder and each of the master cylinder, the outlet port of the pump and the supplementary reservoir and actuating the pump. The inlet control valve is opened when both the brake assist control and the antilock brake control are performed concurrently.

A flame spraying burner melts or partially melts with combustion heat, a spray material comprising a powdered fire-resisting material to thermally spray a damaged portion of a furnace wall or the like. The flame spraying burner includes a burner nozzle body having a central passage for supplying oxygen-contained gas, the central passage having a projecting leading end, and a plurality of fuel gas supply passages formed around the central passage. Each of the plurality of fuel gas supply passages has a leading end recessed from the leading end of the central passage. A cylindrical burner tile is positioned around the leading end of the fuel gas supply passages and extends to at least the leading end of the central passage. A plurality of oxygen jetting ports are formed in the radial direction around the leading end of the nozzle cap.

An electronic control unit includes a braking/driving force control unit configured to control a braking/driving force of a vehicle based on a detected wheel speed, a wheel speed correcting unit configured to correct a detected wheel speed of a certain wheel based on the wheel speed and a wheel speed of another wheel, and a correction prohibiting unit configured to prohibit execution of a correction control of a wheel speed by the wheel speed correcting unit while travelling on a slope road. Whether or not a travelling path of an own vehicle is a slope road is desirably determined based on a difference between an estimated vehicle body acceleration/deceleration estimated from vehicle body speed information and a detected vehicle body acceleration/deceleration detected with a vehicle body front-back acceleration sensor, or based on an output value of a power source.
