Inventor: ISHII FUYUHIKO
IPC: H01L21/302
Filed: 1998-11-20
Abstract: PROBLEM TO BE SOLVED: To improve production efficiency, reduce corrosion of a mixing part and prevent explosive reaction by adding a raw material to fluorine gas stream, evaporating the raw material, mixing both gasses and introducing the mixed gas into a reactor heated at a reaction temperature or above of both gasses. SOLUTION: A halogen other than fluorine, e.g. chlorine and/or a halogen fluoride, such as bromine trifluoride, iodine pentafluoride or the like is used as a raw material to provide the objective halogen fluoride compound such as bromine pentafluoride, iodine heptafluoride or chlorine trifluorine. Nickel, Inconel, Monel, etc., is preferable as the material for evaporator or reactor and the evaporator is equipped with a jacket type thermal insulation apparatus capable of carrying out heating and cooling. The temperature in the evaporator is controlled to nearly boiling point of the raw material and linear rate of fluorine gas is kept to <=30 cm/sec, preferably <=5 cm/sec in order to prevent rapid reaction and corrosion due to the reaction heat.  The gas linear rate in the reactor is controlled to <=10 cm/sec and a baffle plate, etc., is installed in the reactor to provide a structure making stirring and mixing of the gasses efficient.

Title: Infrared sensor
Inventor: KAWAGUCHI TOSHIHIKO
IPC: H01L27/14
Filed: 1988-12-29
Abstract: PURPOSE:To obtain high sensibility and high resolution by forming each phototransistor array to a cascade shape in the depth direction and shaping the arrays only to the surface layer section of a light-receiving effective region. CONSTITUTION:Each phototransistor array N1P1N2P2N3P3 layer is formed to a cascade shape in the depth direction, and formed only to the surface layer sections of light-receiving effective regions 19. Consequently, the phototransistor arrays N1P1N2P2N3P3 are shaped only to the surface layer sections of the light- receiving effective regions 19, thus shortening the diffusion length of electrons and holes generated. Since the lowermost layers N3 of each phototransistor array N1P1N2P2N3P3 and a common semiconductor region P3 are short-circuited or reverse bias voltage is applied to the layers N3 and the region P3, electrons or holes generated at positions deeper than the locations of surface layers are thrown away without being diffused. As a result, a crosstalk is reduced. The phototransistor arrays N1P1N2P2N3P3 are formed to a cascade shape. Accordingly, high sensibility and high resolution can be acquired.

Abstract: PURPOSE:To enable blowing of a large quantity of minus-sieve sintered ores and fine powdered coals at the same time under stable operation in a blast furnace by dividing the minus-sieve sintered ores into fine powdery sintered ore and small grain sintered ore and separately blowing these single bodies and/or the fine powdered coal from upper and lower tuyeres in the blast furnace. CONSTITUTION:The plus-sieve sintered ore is charged from the furnace top opening in the blast furnace and also the minus-sieve sintered ore is blown from the tuyere in the blast furnace to reduce pig iron production cost. In the above blast furnace operation method, the tuyeres are set at two upper and lower steps. The above minus-sieve sintered ores blown from these upper and lower tuyeres are divided into the fine powdery sintered ore and the small grain sintered ore based on the prescribed grain size. These single bodies and/or the fine powdered coal are separately blown from the upper and lower tuyeres. Then, it is desirable that the fine powdery sintered ore is continuously fed and on the other hand, the small grain sintered ore is intermittently fed with high concn. into each tuyere by gas transportation. By this method, feeding trouble is prevented without generating deteriorated furnace condition, caused by worsening of gas penetration, variation of burden dropping, etc., and under the stable operation in the blast furnace, the blowing of a large quantity of the minus-sieve sintered ores and the fine powdered coals at the same time is executed and the pig iron cost is reduced, and flexibility of production is improved.

Title: Magnetic resonance imaging device
Inventor: YOKOI MOTONAO
IPC: G01R33/38
Filed: 1989-12-25
Abstract: PURPOSE:To shorten the photographing time, and also, to miniaturize the device by constituting the device so that two axial directions of an inclined magnetic field coil being orthogonal to three axial directions generate a higher magnetic field than that of the other axial direction. CONSTITUTION:Magnetic field strength in Y0 and Z0 axial directions is that which is larger by about three folds or more than magnetic field strength in the Z0 axial direction. For instance, in the case Y0 and Z0 faces being orthogonal to the X0 axis are set as a slice face, an inclined magnetic field coil for the Z0 axis is formed so as to allow a large current to flow as a read-out inclined magnetic field GR, and to the inclined magnetic field coil for the X0 axis and the inclined magnetic field coil for the Y0 axis, a slice inclined magnetic field GS and an encoding inclined magnetic field GE are applied, respectively. Also, not only three orthogonal cross sections but also a desired slice face having an arbitrary inclined face of single-of-leak, and also, double-of-leak, etc., can be set. Since the inclined magnetic field which can form a high magnetic field is limited two axes, an inclination coil and an inclined magnetic field power source can be miniaturized.
