Title: Granular material transportation ship
Inventor: KANOU MASAYOSHI
IPC: B63B27/24
Filed: 1979-12-28
Abstract: PURPOSE: To reduce the speed of a granular material and gas to prevent the stirring of the material and heighten pile-up efficiency, by changing the direction of a throw-in nozzle to cause the thrown-in material and gas to collide against a reflector when the space of a ship hold is getting short because of the progress in pile-up.  
     CONSTITUTION: A granular material conveyed from a granular material transportation pipe is conducted into ship holds 2AW2F from a load/unload pipe 18 through a branch pipe 37, a flexible hose 38 and a throw-in nozzle 39. When the granular material is piled up to the vicinity of the top of the ship hold 2AW2F, the direction of throw-in from the nozzle 39 is turned toward a reflector 45 to cause the thrown- in material to collide against a reflector 45. As a result, the velocity of the granular material and gas is reduced, their separation is accelerated and the granular material is loaded into the ship holes 2AW2F depending on the reflection angle. Since the velocity of te granular material and gas is reduced, the material is prevented from being stirred.

Title: Manufacture of silicon substrate
Inventor: OGAWA KOJI
IPC: H01L21/322
Filed: 1988-07-11
Abstract: PURPOSE:To obtain a high-quality substrate whose homogeneity is good and which does not cause a defect during an element manufacturing process by a method wherein a heat treatment is executed at a prescribed temperature in an atmosphere of oxygen and an oxygen concentration in a silicon substrate is made substantially uniform with a solid-solution limit at a heat-treatment temperature. CONSTITUTION:A silicon substrate is heat-treated at a prescribed temperature in an atmosphere of oxygen, an oxygen concentration in the silicon substrate is made substantially uniform with a solid-solution limit at a heat-treatment temperature. The heat-treatment temperature is made uniform with a comparatively low oxygen concentration at 1200 deg.C, and is made uniform with a high oxygen concentration which is suitable for an IG wafer. Especially, in a wafer which has been made uniform with an oxygen concentration of 14 to 15X10<17>cm<-3>, its mechanical strength is larger than a wafer of an identical oxygen concentration by a conventional method; when this wafer is heat-treated additionally at 800 deg.C for two hours and at 1100 deg.C for 10 hours, a defect-free layer region becomes uniform inside the wafer and a defect is not caused at all.

Abstract: PURPOSE:To strengthen a weak point without being noticed by a user by forming a reference point in each given question group, allowing the user to input a score obtained based upon answers and issuing respective questions. CONSTITUTION:When the input of a score is instructed by an instruction means 13, a user inputs a score by an input means 14 and the inputted score is stored in the 2nd storage means 15. When the issue of questions is instructed by the means 13, a comparing means 16 compares the score stored in the means 15 with a value corresponding to the reference point stored in the 1st storage means 11, a retrieval means 17 retrieves a question in the succeeding unit when the score is higher than the value of the reference point or the succeeding question in the same unit when the score is lower and a control means 18 offers the retrieved question to an offering means 12. Thereby it is unnecessary for the user himself (or herself) to manage his (or her) records, weak points, and so on.

Filed: 1990-07-02
Abstract: PURPOSE:To prevent involution of slag into molten steel by making depth of tundish only at pouring part in the tundish deep and damping energy in pouring stream to vertical direction. CONSTITUTION:In the tundish 12, where the molten steel 2 in a ladle is poured and flows out into a continuous casting mold, the deep part 14 in the vessel making the pouring part deep, is arranged. By using the tundish 12, even at the time of lowering 4 the molten steel surface level in the case of exchanging the ladle, as the sufficient depth to the stream pouring into the tundish 12 is secured at the position of pouring nozzle 1, the damping of energy in the pouring stream to gravity direction is made large, and even in the case the pouring stream reaches bottom face in the tundish 12, the flowing velocity is made low, and as this turn-over flowing velocity is low, too, mixed quantity of the slag in the ladle is reduced. Further, if necessary, by impressing static magnetic field or shifting magnetic field at the deep part 14 in the vessel, artificially the pouring flowing velocity can be further reduced.

Title: Built-in type data processing system, and method for correcting system program
Inventor: UETOKO KATSUKI
IPC: G06F9/06
Filed: 1999-06-18
Abstract: PROBLEM TO BE SOLVED: To make safely and surely correctable a system program stored in a ROM without preparing a ROM substituting/rewriting system or a hook mechanism. SOLUTION: An address conversion part 121 in a bus controller 12 is utilized for correcting a trouble of an operating system(OS) stored in a ROM 13. Namely, when a trouble of the OS is detected, an address conversion part 121 converts the value of a physical memory address outputted from a CPU 11 in order to specify an instruction causing the trouble in the ROM 13 into the value of a physical memory address in which a corrected instruction exists. Thereby, the corrected instruction is entered into the CPU 11 instead of the instruction causing the trouble. Consequently, the OS can be safely and surely corrected without preparing the substituting/rewriting system of the ROM 13 and a hook mechanism.

When the cross-sectional area of the respective low melting point fusible alloy pieces 5 is set no more than 0.8 mm<2> , it is easily disrupted into sections, and a disruptive speed also quickens by individual staged disruption by dispersion. The parallel number of the low melting point fusible alloy pieces 5 is set according to electric current capacity.
