摘要:
This invention is a lubricant comprising an imide compound obtained by reacting a dibasic acid selected from the group consisting of succinic acid, maleic acid, glutaric acid and phthalic acid with a primary amine having a C.sub.8 -C.sub.18 hydrocarbon radical.The lubricant of the invention may be used in combination with a specified diamine derivative and known lubricant additives, and exhibits excellent lubricating properties.
摘要:
There is disclosed a lubricant the major portion of which is composed of Duomeen-T-dioleate. It may be associated with a diamide compound of the formula ##STR1## wherein R.sup.1 is a C.sub.2-4 alkylene radical and R.sup.2 is a C.sub.14-18 alkyl or alkenyl radical, or with various kinds of thickeners and/or waxes. The resulting lubricant has superior performance when applied to a metal-metal, metal-plastics or plastics-plastics sliding surface.

This invention relates to precisely obtaining a head temperature free from influence of a signal transferred to a printhead, without slowing down the printing speed. In a printing apparatus which includes a printhead including a plurality of printing elements and a temperature sensor, and divides the plurality of printing elements into a plurality of blocks to print while performing division driving of the plurality of printing elements for each block, the head temperature is detected as follows. First, one printing period determined by a printhead driving frequency is divided into an active period required for the division driving and an inactive period required for A/D-converting an analog temperature data signal from the temperature sensor. While a signal required to drive the printhead is transferred in the active period, a digital signal A/D-converted from the temperature data signal from the printhead is read in the inactive period.

A recording apparatus performs recording with a recording head having a number of recording elements divided into blocks. The recording apparatus includes a signal generation unit to generate first enabling signals based on inclination information associated with each of the blocks of the recording elements. The first enabling signals are used to enable a data generating unit to generate recording data on a block-by-block basis. The signal generation unit further generates second enabling signals that correspond to the respective first enabling signals delayed by a time interval and enable the recording elements to be driven on a block-by-block basis.

In this exposure system, alignment marks on a photosensitive material are photographed with a reading unit. Prior to this photographing, a standard board, having detection marks at positions readable to the reading unit at preset intervals along the movement direction of the reading unit, is provided. At least one of the detection marks is photographed with the reading unit, which is arranged in a position to photograph the alignment marks provided on the photosensitive material. Calibration data is calculated based on data on the camera optical axis deviation obtained by this photographing. Standard position data reflects the calibration data, whereby calibration of the exposure position adjustment function of the exposure device is performed.
摘要:
An image recording apparatus including a recording head in which a plurality of recording element assemblies are arrayed in x direction as a unit, the plurality of recording element assemblies each being equipped with an optical system for forming a light beam and focusing the light beam to the recording surface of an image recording medium, wherein the recording head and image recording medium are relatively moved in y direction that intersects the x direction substantially at a right angle with respect thereto, to thereby record an image onto the image recording surface, the image recording apparatus includes: mark reading means that is disposed adjacent to the recording head and that reads a positioning mark provided on the image recording medium, wherein, while the image recording medium is moved in the y direction, reading of the mark by the mark reading means and recording of the image by the recording head are executed, and the mark reading means estimates in advance the deformation of the mark that occurs as a result of reading performed during the movement of the image recording medium and recognizes the relative position of the image recording medium with respect to the recording head on the basis of set position data of the positioning mark of which deformation has been estimated and the position data of the positioning mark that has been read.
摘要:
An annular rail 6 is fixed on the lower surface of a moving hearth 2, and the rail 6 is supported from below by support rollers 7 provided with elevating devices 8. The moving hearth 2 is continuously or intermittently moved downward by the elevating devices 8 depending on the thickness of a metal oxide layer formed by the deposition of powder of metal oxide agglomerates mixed into the furnace together with the metal oxide agglomerates so that a gap is provided between the surface of the metal oxide layer and the edge of the blade of a discharge screw 4 during operation. A means for preventing the formation of a metal plate and a method for operating the same are provided instead of a means and method including the vertical movement of a discharger for reduced metal, so that the maintenance work can be significantly reduced in a moving-hearth heating furnace, in which metal oxide agglomerates containing a carbonaceous material is placed on a moving hearth, the metal oxide agglomerates are heated and reduced to form reduced metal agglomerates, and the reduced metal agglomerates are discharged from the furnace by a discharger to produce reduced metal.
