Title: Multi-color head-up display
Inventor: ISHIKAWA TOSHIHARU
IPC: G02B27/01
Filed: 1991-12-20
Abstract: PURPOSE:To obtain a multi-color head-up display having a comparatively simple formation process and using a holographic combiner prevented from the reduction of diffraction efficiency due to multi-coloring. CONSTITUTION:The face of the holographic combiner C is divided into plural groups of fine areas so that respective adjacent fine areas belong to other groups, interference stripes based upon two beams having the same arrangement due to the same wavelength are recorded in the fine areas of each group R, G, or B so that the interference stripes of the adjacent fine areas are not mutually and practically overlapped and interference stripes corresponding to another wavelength are recorded in a different group. Consequently the reduction of diffraction efficiency due to the multiplication of interference stripes can be prevented, the diffraction efficiency of each wavelength is distributed in accordance with the area ratio of the area, 100% diffraction efficiency can be obtained in total, and a bright multicolored display can be obtained.

IPC: C21B5/00
Filed: 1994-12-28
Abstract: PURPOSE: To reduce the iron-making cost by continuously measuring the quantity of reaction of pulverized coal in the furnace when pulverized coal is injected from the tuyere of the blast furnace, and achieving the feedback of the results as the control factor of operating the blast furnace to reduce the coke ratio in the blast furnace operation. CONSTITUTION: Inexpensive pulverized coal is injected together with the hot air from the tuyere when the blast furnace is operated so as to reduce the coke ratio by reducing the use of the expensive lump coke for the blast furnace. The amount of the discharged dust is obtained from the amount of the discharged gas from the top of the blast furnace and the concentration of the dust in the gas, and compared with the amount of the dust when pulverized coal is not injected from the tuyere to calculate the amount of the generated dust by the injection of pulverized coal. The quantity of reaction of pulverized coal in the blast furnace is obtained from the amount of the dust and the amount of pulverized coal injected from the tuyere, and the temperature rise of the hot air from the tuyere and the increase of the oxygen enriched ratio are appropriately controlled according to the result.  The use of pulverized coal is increased as much as possible by increasing the quantity of reaction of pulverized coal, and reducing the use of the coke for the blast furnace to reduce the coke ratio and reduce the iron-making cost the of blast furnace.

Filed: 1992-12-21
Abstract: PURPOSE:To appropriately consume toner and to always obtain high image quality by controlling the stirring time or stirring speed of developer or forcibly consuming the toner in accordance with the consumption of the toner per unit print. CONSTITUTION:The weight of toner is measured by a weight sensor, and a difference between the measured weight value and a stored value in a previous integrated weight memory part is obtained by a consumption arithmetic part and divided by the specified number of copies to calculate the toner consumption per unit number of copies. The obtained toner consumption is compared with a 1st reference value in a comparison part, and it is successively compared with 2nd and 3rd reference values in the case it is smaller than the 1st reference value. Then, the stirring time of a stirring motor is controlled stepwise by a developer stirring control means so that it may be made shorter than usual or the speed of the stirring motor is controlled to be slow. In the case the toner consumption is smaller than the 3rd reference value, the deteriorated toner is forcibly consumed by a toner forcibly consuming means by judging that the deteriorated toner exists in a developing device.
