Abstract: PURPOSE:To obtain a color copying machine whose manually adjusting time is shortened and whose producing efficiency is improved. CONSTITUTION:The positions of a slit 8a and the leading edge of 30a of a toner image 30 on a transfer belt 8 are detected by a sensor, and deviation between the respective leading edges of the toner image 30 and a paper is calculated by a calculation means.

Based on the arithmetically operated result, the rotation of a scanner motor is controlled to automatically adjust the leading edges of the image and the paper. The deviation between the respective leading edges of a blank paper transfer trace and the paper is calculated by the calculation means, and based on the calculated result, the adjusted value of paper feeding with which the positional deviation of the leading edge 30b of the virtual image and the leading edge of the blank paper transfer trace on the transfer belt 8 is eliminated is arithmetically operated by the control means. Based on the arithmetically operated result, the rotation of a resist roller is controlled to automatically adjust the leading edge.

IPC: H04N1/032
Filed: 1993-10-21
Abstract: PURPOSE:To reduce the deterioration in picture when received information is reduced at a receiver side specifying the difference of transfer times of each transfer information to a predetermined or below at reduction recording. CONSTITUTION:A clock generating circuit 32 outputs e.g. 20MHz clock BCLK. In the case of recording at a rate of 8 pel/mm in the main scanning direction, after signals being 1/8 frequency divisions of the BCLK are counted by a number of 40, the same information is outputted in relation to 8 signals BCLK. Upon the detection of a predetermined number of signals BD after the detection of a level 1 of a signal TOP, a picture information processing circuit 34 counts 40 signals DCLK from a timing of a signal BD and then outputs one line of received information by one line and then the processing above is repeated. In the case of nonmagnification, after 40 signals DCLK are counted from a timing of the signal BD, picture information is outputted and even in the case of reduction, similarly after 8X40 signals BCLK are counted after detection of the signal BD and reduced data are outputted. A control circuit 38 samples data based on a 20MHz clock faster than the transfer clock 20MHz/8 by 8 times to control the difference from the transmission times at recording recording into 1/20MHz or below.

Title: Production of metal powder
Inventor: SATO YOSHITOMO
IPC: B22F9/08
Filed: 1986-11-27
Abstract: PURPOSE:To permit efficient production of metal powder having a small particles size by converting the molten metal flow dropping from a nozzle to film-like flow and blowing an atomizing medium uniformly thereto at the time of producing the metal powder by an atomization method. CONSTITUTION:The molten metal 1 in a tundish 2 falls when a stopper 5 is pulled up. The falling molten metal strikes against the top part of a molten metal dividing body 4, by which the molten metal is divided. The divided molten metals flow along the slope of a circular conical body and the molten metal TM which is columnar is changed to the film-like molten metal M. The molten metal flow converted to the thin film is rapidly cooled and splashed when the atomizing gas is directed and injected toward the tail part of the dividing body 4. The molten metal is, therefore, extremely finely divided by the atomization. The circumferential length of the tail part of the body 4 increase if the vertex of the body 4 is selected at a large angle. The film forming efficiency of the molten metal is thereby improved.
