摘要:
An ink jet recording apparatus with plural full-line type recording heads has a heat pipe associated with each recording head. The heat pipes are connected together at a common portion in various ways, such as by a heat-conductive block, one or more additional heat pipes or a container with a heat transferring liquid medium. Such an arrangement enables more efficient and compact temperature control of the recording heads.

A recording medium in the sheet form is supplied into a designated direction guided by a sheet supply roller. An ink jet recording head in which a plurality of ink jet discharging orifices are arranged is placed in parallel with a surface of the recording sheet and in the direction perpendicular to the designated direction of supplying the recorded sheet. An adjustment screw is placed for correcting a warped shape of the ink jet recording head by means of displacing a neighbor of a central portion of a longer side of the ink jet recording head in the designated direction of supplying the recording sheet.

A valve operation control system for an internal combustion engine having a cam-shaft and a crank-shaft has an adjusting device for adjusting a phase difference between the cam-shaft and the crank-shaft by being supplied with hydraulic pressure, a driving device integrated with the adjusting device and having an oil pump driven by the cam-shaft and a hydraulic pressure line between the oil pump and the adjusting device, and a hydraulic pressure control device disposed in the hydraulic pressure line for regulating the hydraulic pressure to be supplied to the adjusting device.
摘要:
A recording apparatus includes an ink jet recording head having plural ejection outlets and thermal energy generating elements provided for the respective ejection outlets; a signal supplying device for supplying a recording signal to said recording head; a detector for detecting a state relating to heat, on the basis of the recording signal supplied from the signal supplying device; and a controller, responsive to the detector, for actuating the thermal energy generating element. The apparatus maintains the viscosity of the ink in the recording head lower than a critical ejection viscosity.

An image forming apparatus has an image bearing member; a toner image forming device for forming a toner image on the image bearing member; a transfer charger for transferring the toner image from the image bearing member onto a transfer material; a first detector for detecting toner charge amount before image transfer onto the transfer material; a second detector for detecting the efficiency of the image transfer; and a controller for controlling a condition of image transfer operation in accordance with outputs of the first and second detector.
摘要:
A method of and an apparatus for recording an image on a recording medium. A heat-sensitive sheet having a light-transmissive base sheet provided with a heat-fusible supercooled substance layer is made to abut a copy original such that the heat-fusible supercooled substance layer faces the original image to be copied while flashlight is projected onto the base sheet of the heat-sensitive sheet. Thus, the image portion of the copy original to be copied absorbs the light transmitted through the heat-sensitive sheet and thereby generates heat so that an adhesive area containing a pattern corresponding to the original image is formed on the supercooled substance layer. After the heat-sensitive sheet has been removed from the copy original, such an adhesive area is transferred to the recording medium owing to the adhesiveness of the adhesive area.
摘要:
An electromagnetic valve has an electromagnetic coil, a main body arranged adjacent to the coil, a fixed core arranged inside of the coil, and a movable core arranged inside of the coil and beside the fixed core such that a space exists between the movable and fixed cores. A cylindrical sleeve is arranged on a side surface of the main body and a cylindrical spool valve is arranged in an inner portion of the cylindrical sleeve such that the spool valve forms a step portion. A gap communicates with the space between the movable and fixed cores, while at least one opening in the body of the spool valve communicates the interior of the spool valve with the step portion. An intermediate plate in the form of an annular plate with a plurality of radial grooves can be arranged between the main body and the sleeve.
