Abstract: PROBLEM TO BE SOLVED: To convert thermal energy of an oxide viscous melt at an ultrahigh temperature into chemical energy and recover the thermal energy in the form of heat of reaction by atomizing the oxide viscous melt with a cup atomizer and blowing a reactional substance in the form of a jet thereon. SOLUTION: An oxide viscous melt (a blast furnace slag) 1 is charged into a cuplike vessel 2 rotating at a constant angular velocity and the oxide viscous melt 1 is scattered from the edge of the cup to the surroundings with a centrifugal force 3 in the cup and converted into microparticles 4. A reactional gas (CH4+H2O) 5 in the form of a jet is then blown from the lower side upward along the cup on the microparticles 4. The oxide viscous melt 1 just after scattering from the cup increases the surface area thereof while maintaining a high temperature and is brought into contact with the reactional gas 5 in the form of the jet at a high efficiency to initiate a reaction.

Filed: 1992-10-28
Abstract: PURPOSE: To prevent a film holder from approaching a patient by placing the film holder in a waiting position opposite to the inner periphery of a C-arm when it is not used. CONSTITUTION: A film holder 6 and its support frame 5 are opposed to the inner periphery of a C-arm 1, and since the film holder 6 is kept from a patient region so as not to obstruct the vision and approach of the operator and does not project beyond the outer periphery of the C-arm 1, it does not limit the movement of the C-arm 1. The film holder 6 can be moved to a prepared position on the same plane as an X-ray detector 4 by moving the support frame 5 about a shaft 7 by about 45 degrees. Next, the film holder 6 is rotated about a shaft 12 by about 90 degrees and thereby its photographic position can be moved.  Since the film holder 6 is not attached to the X-ray detector 4, counterweights 8, 9 can be small in mass, be flattened, and move inside the outer periphery of the C-arm 1 immediately below an outer storage device, so that the approach to the patient region is further improved, and that the C-arm can be moved manually.

Title: Pseudo fault generator
Inventor: MATSUSHITA NAOYUKI
IPC: G06F11/22
Filed: 1993-12-14
Abstract: PURPOSE:To detect the occurrence of a real fault while internal diagnosis is being performed by a host device and to confirm the normalcy of fault notification even for a CPU reset fault by masking the fault notification to the host device when the internal diagnosis is rendered, and storing a fault to reset the CPU of a device when it occurs. CONSTITUTION:The CPU 11, when receiving an internal diagnosis instruction from the host device 2, masks the notification of the fault to the host device by operating a host notification masking circuit 16 or 17, then conforms the notification of the fault to the CPU 11 by operating a pseudo fault generation circuit 12 or 13. Also, when the fault to reset the CPU 11 occurs, the CPU 11 gives an operation instruction to the host notification circuit 17 before reset, and the reset of the CPU 11 is stored in the host notification circuit 17 by generating a pseudo fault for the internal diagnosis. The CPU 11 reads out whether or not the operation instruction of the host notification masking circuit 17 is executed after reset, and continues the internal diagnosis by judging that the pseudo fault to reset the CPU 11 is generated by the internal diagnosis when the operation instruction is executed.
