Title: Cold rolling method for black-skinned steel sheet
Inventor: HINOTO HAJIME
IPC: B21B27/10
Filed: 1979-11-30
Abstract: PURPOSE:To omit the pickling work from the pretreatment process, by applying the rolling work to the hot rolled steel sheet as it is black-skinned, while directly applying the rolling mill oil to the surface of the rolled sheet. CONSTITUTION:The rolling mill oil is prepared as a pure oil excluding water, from one or mixture of mineral oils, oil-and-fats, and synthetic oils. This oil becomes more effective by adding it the lubricity improving agent, antioxidants, the rust preventive agent, etc. This oil is applied to the surface of the rolling roll or to the biting part of the rolling roll, or to the surface of the steel sheet between two stands.

Title: Magnetic dust separator
Inventor: MURAKAMI KENICHI
IPC: B03C1/02
Filed: 1977-12-23
Abstract: PURPOSE: To provide a process consisting of in which metallic particle attachment is let off outside a magnetic field captured and collected by a lower take-out mechanism and discharged by providing an intermediate dust box in a suction and discharge system and forming said magnetic field in the flow passage of dust.  
     CONSTITUTION: The metallic dust containing magnetic metal particles flows in an intermediate dust box 25 through a piping 4 and is adsorbed onto an outer tube 9 by a magnet 7. As the adsorption and accummulation of magnetic metal particles progress to some extent, some portion thereof falls down through natural peeling-off. However, the metal particles adsorbed after transferred through said outer tube 9 by a cylinder 11 can be completely peeled off when carried out of magnetic field. In the meanwhile, the adsorption of metal particles is performed at the other end of said outer tube so that the metal particles attached there fall down through peeling-off when said cylinder 11 has returned to illustrated initial position. Thus, the adsorption and peeling-off of metal particles are repeated through the reciprocation of said outer tube 9 so that magnetic metal particles can be continuously separated in said box 25.

Title: Transcription system
Inventor: KOUKAI TAKAYUKI
IPC: G03G15/16
Filed: 1980-11-05
Abstract: PURPOSE:To increase the transcription efficiency, by securing the difference of shift speed between a recording medium and a latent image forming medium which are shifted in a fixed speed at a transcription part. CONSTITUTION:The speed of revolution of a photosensitive drum 1 is increased by varying the speed reduction ratio of a speed reduction mechanism 3 of the drum 1. As a result, a latent image produced by a laser optical unit 6 extends in the turning direction (indicated by arrow 4) of the drum 1 and has a regular size on the paper 10 since a shift is caused by a difference of speed between the drum 1 and a paper feed tractor 16 which is produced at the part of a transcription part guide 11. However, the transcription start position 22 advances slightly by the change of the rotational frequency of the drum 1. In this respect, a compensation must be given to the transcribing position or the paper stopping position. For the difference of speed, the good printing is possible by raising up the drum 1 by about 1.6%. A satisfactory result is impossible at a value of <=1.0% and >=2% respectively.
