Title: Carrier for developing electrostatic latent image
Inventor: YASUNAGA HIDEAKI
IPC: G03G9/107
Filed: 1995-03-17
Abstract: PURPOSE: To attain satisfactory electrostatic charge of a toner even when a toner having a small particle diameter is used so as to form a high quality image and to stably carry out satisfactory image formation by using a 1st carrier holding magnetic powder stuck to the surface and having a specified average particle diameter and a specified saturation magnetization or below and a 2nd carrier having a specified average particle diameter and a specified saturation magnetization or below. CONSTITUTION: This carrier contains a 1st carrier holding magnetic powder stuck to the surface and having 80-150μm average particle diameter and <=50emu/g saturation magnetization and a 2nd carrier having 30-50μm average particle diameter and >=55emu/g saturation magnetization. The reason for 80-150μm average particle diameter of the 1st carrier is that the flowability of a developer cannot be satisfactorily improved in the case of <80μm and the charging property to a toner is deteriorated in the case of >150μm. The reason for <=50emu/g saturation magnetization of the 1st carrier is that the flowability of a developer and the reproducibility of thin lines are adversely affected in the case of >50emu/g. A carrier having 90-100μm average particle diameter and 45-50emu/g saturation magnetization is preferably used.

Title: Rotary angle detecting device
Inventor: JIYOU RIYOUSUKE
IPC: G01B7/30
Filed: 1981-06-04
Abstract: PURPOSE:To reduce the number of parts and to improve reliability by multiplying a signal by a frequency multiplier, and outputting the signal having a constant frequency without excess or shortage at a low speed rotation. CONSTITUTION:The frequency multiplier 2 generates a rectangular wave C1 having the constant frequency of 3kHz at the low speed rotation of 500rpm or less of the engine speed, and generates a rectangular wave C2 having the frequency four times the input signal at the high speed rotation. The output signal of a counter 32 becomes a reset signal of a gate pulse (f). The rectangular waves C1 and C2 pass a gate circuit. Rectancular waves f1 and f2 each having 4 pulses are outputted for every one input signal. The signal f1, which is obtained at the low speed rotation of 500rpm or less, is shifted from the signal for every one degree. However, accurate control which is synchronized with the rotary angle is not required at the rotation number of an idle rotation or less. Therefore, the signal can be used as the rotary angle signal for the control of an internal combustion engine. In this way, the number of the parts in the rotary angle detecting device can be reduced, and the costs can be reduced.

Filed: 1989-04-04
Abstract: PURPOSE:To obtain the refractory which is not significantly eroded by glass and generates only a small amt. of bubbles by infiltrating a soln. contg. metal alkoxides into the pores of the refractory and then calcining the refractory to form a vitreous or crystalline material in the pore. CONSTITUTION:A soln. contg. metal alkoxides (e.g. a soln. of tetraethoxysilane., etc., or the soln. added with NaCl, AlCl3, etc.) is infiltrated into the pores of the refractory (e.g. the silica-alumina-based calcined refractory and chromium- based calcined refractory having about 10-25% porosity and <=40mu pore diameter), and the refractory is then calcined to form a vitreous or crystalline material in the pore. Since the erosion of the calcined refractory is reduced and the generation of bubbles is also reduced, the service life of a sleeve made of the calcined refractory is prolonged, and the yield is also increased.

Abstract: PURPOSE:To control the air permeability and central position of reduction reaction of a blast furnace and to attain the stable operation of a blast furnace by classifying the intermediate grain sizes set at about the same degree in the air permeation resistance in the blast furnace in order to lessen the air permeation hindrance by the extreme classification of coke, such as large lumps and small lumps, of the coke to be used in the blast furnace. CONSTITUTION:A sieve for classification of the coke grains is added to sieves to make the sieves in three stages. The second 8 and third 9 thereof are so set that the intermediate grain sizes between the min. grain size and max. grain size of the coke usable in the blast furnace can be classified, by which the coke is classified to two kinds; the lump coke including the min. grain size and the max. grain size and the medium lump coke including only the intermediate grain sizes. At this time, the air permeation resistances of the lump coke and the medium lump coke in the blast furnace are set at about the same degree. The lump coke and the medium lump coke are charged continuously respectively one time each and such charge is basically decided as one charge in the blast furnace operation. This charging ratio is changed by the air permeability in the blast furnace.
