Title: Optical scanner
Inventor: NARISAWA HIDETSUGU
IPC: B41J2/44
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To provide an optical scanner capable of changing light qunatity at a low cost without using any filter. SOLUTION: The main scanning direction beam width of a laser beam 32 made incident upon a polygon mirror 24 is larger than the length of one face 24A of the mirror 24. The laser beam 34 is converted into a weak divergent light through a collimeter lens 14 and then converted into a beam approximately parallel with the main scanning direction through an expert lens 22 and made incident upon the mirror 24. When the lens 22 is moved to the laser diode 12 side, the width of the laser beam 32 made incident upon the lens 22 is narrowed and the main scanning direction width of the laser beam 32 made incident upon the mirror 24 is reduced. Since the center part of the beam 32 has strong energy distribution, the light quantity of a beam made incident upon a photosensitive body can be increased.

Title: Development for color copier
Inventor: TAGIWA IZUMI
IPC: G03G15/01
Filed: 1978-02-24
Abstract: PURPOSE: To restrain the blot in texture due to a marked chromatic toner so that it may be prevented as a whole by using the development having a high edge effect in a chromatic toner development.  
     CONSTITUTION: The relationship between the image density of a line image 1, a gang image 2 and a texture blot 3 and the pressure in a magnet brush is shown to exhibit a peak at the center so that the density is reduced no matter how low and high the brush pressure is. More specifically, it is found that the both end portions a and b are a region having a high edge effect and it is also apparent from the graph that the texture blot is reduced. In the dichroic copy of red and black colors, therefore, the consumption of red is limited  to a region defined by an under line and a frame. By adopting the development having a high edge effect, therefore, it is possible to make the texture blot less apparent as a whole.

IPC: C21C5/46
Filed: 1979-02-24
Abstract: PURPOSE:To reutilize the residual slag so as to reduce the cost and to improve the productivity, by, in charging slag-making agent on the surface of a molten metal bath contained in a molten metal vessel, measuring the quantity of the molten slag remaining in the vessel by a specific, indirect method, and by replenishing the slag- making agent under the initial conditions determined by the measurement described above. CONSTITUTION:Before blowing, the internal shape of a converter is measured by means of an instrument 7, and the results are stored in a memory arithmetic unit 9. After blowing and tapping, the converter 1 contg. residual molten slag in it is made to stand upright, and the molten slag level is measured through an opening made in a hood 6 by means of a molten slag-level-measuring instrument 8, and the results are stored also in the arithmetic unit 9. Then the internal shape of the converter and the molten slag level when the converter stands upright, both which are determined by measuring, are expressed in an absolute co-ordinate by the memory arithmetic unit with, e.g., one point of the furnace throat used as an origin, and the volume of the molten slag is calculated on the basis of the values represented by the co-ordinate. On the other hand, the analyzed values of the residual molten slag components are transmitted together with the volume of the residual molten slag obtained by the arithmetic unit 9 to a converter-process computer 10, whereby the specific gravity and the weight of the molten slag is calculated. The slag making agent is replenished using the residual molten slag quantity thus obtained as the initial conditions.

The molten metal surface control panel 6 adjusts so as to keep the uniform level of the molten metal surface. In this way, a length of casting billet is controlled uniformly and the yield of the products is improved.
