Patent JP-H01274882-A (JP)
Title: Pneumatic classifier
Inventor: MUNEDA YOSHIAKI
IPC: B04C9/00
Filed: 1988-04-26
Abstract: PURPOSE:To improve classifying efficiency by providing a classifying casing successively to an upper casing via a discharge pipe, providing a cyclone to the outside of the classifying casing and providing a tapered dashboard to the outside circumference of the rear surface of an upper diffusion plate. CONSTITUTION:Raw materials 25 charged from a raw material charge port 24 enter the top of a lower diffusion plate 17 and are splashed in the outside circumferential direction by the centrifugal force thereof. The greater part of the raw materials move along the rear surface of the upper diffusion plate 16 and collide against the dashboard 19, by which the dispersion thereof is intensified and the materials are adequately loosened. The raw materials 25 simultaneously receive the two forces of the diametrical directions; the outward centrifugal force and the inward air resistance in the radical direction. The particle diameter at which these two forces balance each other is determined as a classification point and the particles below the classification point are entrained in the circulating air flow generated by classifying vanes 18 and are fed into a classifying chamber 20 of the upper casing 11. The grains are then supplied through a discharge pipe 31 for a dusty gas to the cyclone 2 where the fine grains in the air flow are recovered. The air flow from which the fine grains are separated is then returned to the lower casing 12 and is used as the classifying air flow.

Title: Refractory for molten metal and molten iron treating vessel
Inventor: HAMAI KAZUO
IPC: C04B35/10
Filed: 1989-04-20
Abstract: PURPOSE:To enhance the lifetime of the vessel in the high-temp. oxidative atmosphere by incorporating the specified amount of alumina, carbon and Al. CONSTITUTION:This refractory for molten metal consists of by weight 70 to 94% Al2O3, 3 to 20% C and 3 to 10% Al. At least 10 to 30% of Al2O3 particle is constituted of particles having <=44mum and Al powder is constituted of particles having <=44mum. When this refractory is utilized in the high-temp. oxidative atmosphere, the partial pressure of O2 is lowered and the partial pressure of CO is raised in a matrix constituted of graphite, fine Al2O3 particles and metallic aluminum powder. Therefore, Al and Al2O3 are allowed to react with C, respectively and Al4C3, Al4C3 +CO2 and carbide are deposited and the matrix is made dense. In the operating surface, Al4C3 is allowed to react with O2 and fine Al2O3 particles are deposited and sintered together with Al2O3 in the matrix and a dense layer is formed. The abovementioned refractory is made inferior in heat resistance, thermal shock resistance and resistance to slag penetrability in C<3%. Resistance to oxidation is remarkably lowered in C>20%. Further a difficult point is caused in resistance to oxidation in Al<3%. Generation of a crack is accompanied in Al>10%.

Inventor: ADACHI EIICHI
IPC: H04N1/333
Filed: 1982-06-14
Abstract: PURPOSE:To attain data communication at a proper MODEM rate, by comparing shift-down conditions between the transmitting side and receiving side, and setting up the shift-down condition adapted to the side inferior in line quality. CONSTITUTION:A device B on the receiving side discriminates the quality of the line at the self-position, sets up the shift-down condition (frequency of automatic repeat requests) in an NSF frame and sends the set up condition to a device A on the receiving side. The receiving device A compares the sent condition with a fixed shift-down condition, adopts the lower shift-down condition and sets up the adopted condition in a shift-down condition discriminating circuit 7. The circuit 7 counts up the frequency of repeat requests, and if the frequency exceeds a fixed value, informs that the shift-down condition is formed to a control circuit 1. Receiving a shift-down command from a control circuit 1, a sending controlling circuit 5 stops information input at the point of time when the information of one frame is inputted and returns the status indicating the understanding of shift-down. The control circuit 1 switches MODEM from a high speed MODEM 4 to a low speed MODEM 3.

Title: Semiconductor device
Inventor: OOSHIMA HIROYUKI
IPC: H01L21/331
Filed: 1980-07-25
Abstract: PURPOSE:To obtain a semiconductor integrated circuit for a liquid crystal displaying panel which leaks little currents even when external light is irradiated on the surface by forming a region with the high concentration of impurities extending over a range that does not exert an adverse effect on a circuit element. CONSTITUTION:The P<+> diffusion region 19 is formed selectively to a P type monocrystal Si substrate 8, a P<-> monocrystal Si film 10 is grown in an epitaxial shape, and a P<+> diffusion region is further molded selectively. Consequently, a P<-> region 11 with the low concentration of impurities is formed in a shape that is surrounded by the P<+> diffusion region 9 with the high concentration of impurities. The element is shaped afterward in the P<-> region 11 according to a manufacturing process of a normal MOS type transistor. Accordingly, since the concentration of impurities of the P<+> diffusion region 9 is higher than that of the substrate 8, most carriers recombine with a large number of carriers in the P<+> diffusin region, and the number of a small number of carriers reaching to a PN junction region decreases.

Title: Dry multiple disk clutch
Inventor: MIZUKAMI YUJI
IPC: F16D13/52
Filed: 1994-05-17
Abstract: PURPOSE:To prevent excessive temperature rise of a friction plate to lengthen its life by taking the outside air from a hole formed on a pressure plate into the inside space so as to cool the friction plate. CONSTITUTION:When a pressure plate 3 is energized by an elastic member 32, a first friction plate 15 and a second friction plate 16 are pressed to each other to transmit torque from the input member 1 to a hub flange 8. When the pressure plate 3 is moved in the direction of separating from the first friction plate 15 by a clutch disconnect mechanism 9, the press-contacting condition between the friction plates is released to interrupt torque transmission. When the clutch is connected, heat is generated between both friction plates. Especially, in the case of decreasing the number of friction plates for reducing the weight, the friction plates easily become high temperature as the load of the friction plate is large. Accordingly, the outside air is taken in the internal space from holes 41, 42 formed on the pressure plate 3 to cool both friction plates 15, 16 through a path 45 of the second cylindrical part 20. Thus, at the time of pressure-contact of the friction plates, excessive temperature rise can be prevented so as to lengthen its life.
