Filed: 1987-05-25
Abstract: PURPOSE:To execute a good and stable optical scanning by constituting a rotary polygon mirror of even pieces of plane-like reflecting surfaces so that an incident light beam is reflected even times, and also, placing a reflecting mirror for reflecting an emitted light beam of a collimator lens, so that the light beam is made incident toward the rotary polygon mirror. CONSTITUTION:Each reflecting surface 1a, 1b which is arranged in the peripheral direction of a rotary polygon mirror 5 is constituted of even pieces of plane-like reflecting surfaces Ia, Ib so as to reflect an incident light beam even times. Also, in a plane where a light beam I from a light source 2 contains a revolving axis 6 of the rotary polygon mirror 5 and orthogonal to the surface to be scanned, a reflecting mirror 8 for receiving an emitted light beam Io of a collimator lens 3 and reflecting the light beam toward the rotary polygon mirror is placed between the rotary polygon mirror 5 and the collimator lens 3, so that the light beam is made incident toward the rotary polygon mirror 5. In such a way, the displacement of a scanning line in the direction vertical to the scanning line can be eliminated.

Filed: 1978-10-18
Abstract: PURPOSE: To fill molten metal to all corners of molds before it freezes, eliminate defects such as shrinkage, misrun, etc. and improve quality by giving vibrations to the molds having been poured with molten metal.  
     CONSTITUTION: Molten metal is poured in the cavity 10 of molds 9, 9' in a pouring station 11 to the metal molds 9, 9' having been mounted to a bed plate 7 and pressed to a frame 3 by rails 6a, 6b. Next, before the molten metal freezes, the molds are sent to the next exciting station 1. Then, an excitor 4 starts vibration by the transfer confirmation signal thereof. The molds are vibrated in various ways, i.e., slowly first and increasingly faster at small amplitudes first then large amplitudes and finally small amplitudes so that the molten metal reaches all corners of the cavity 10 of the mold during the time from a molten state to a semi-molten state. When the excitation is stopped by a timer, the molds are sent to the next station 1'. Here, too, the excitation is started by the transfer confirmation signal in the similar manner as before, whereby the adjustment before freezing from the semi- molten state to a solid state is accomplished. The excitation is stopped by a timer.

Abstract: PURPOSE:To obtain a lithographic aluminum substrate having a plate wear endurable for a large number of printing, by a method wherein, a film having a resistance to electrolytic roughening is formed prior to the electrolytic roughening of an aluminium plate, and the aluminium plate is electrolytically roughened. CONSTITUTION:An aluminium plate in use includes a pure aluminium plate and an aluminium alloy plate. The surface of the cleaned aluminium plate is electrolytically treated to form thereon a film having a resistance to electrolytic roughening. At this time, the film is formed by a method in which an electric current having such a voltage waveform as sine voltage waveform, saw-tooth voltage waveform, or triangular voltage waveform, which has a peak voltage in anode at 1/3 or after of an anode cycle, is passed between the aluminium plate and an electrode opposed thereto in a nitric acid electrolyte. In this manner, pits are formed deep and uniform by an electrolytic roughening process. The film formed by the electrolytic treatment preferably has a thickness of 0.001-0.5g/m<2>. As a result, by using the roughened aluminium plate as a substrate, a press plate free from the stain in a non-printing area and having a superior plate wear durability is made available.
