Title: Method for charging fuel element to pebble bed type reactor and pebble bed type reactor for executing said method
Inventor: TEUCHERT EBERHARDT
IPC: G21C1/07
Filed: 1985-09-20
Abstract: A ball-bed (pebble-bed) nuclear reactor, instead of having fuel elements more or less continuously withdrawn and new or reconstituted fuel elements more or less continuously reintroducted, is initially partly filled with fuel balls of which two-thirds have a fissionable material content 12% below and the upper third 24% higher than the average content. This filling meets the requirements of criticality in order to begin operation. Thereafter, fuel balls are added slowly, a few hundred per day, having 150 to 250% of the average fissionable material content of the initial loading, thus preserving the criticality requirments, while keeping the temperature within safe limits until the reactor cavern is filled. Thereafter, the reactor is shut down, cooled off, pressure relieved and emptied, the last step typically from above. An ordered array of the fuel balls in regular layers avoids excess pressure loads on the reflector over the life time of the filling. For a random packing of the balls a cross-section of the cavern that increases somewhat from the bottom upwards also avoids the excess pressure loads on the reflector.

Abstract: PURPOSE:To improve a migration resistance by forming an extremely thin insulating film on the exposed surface of the diffused layer when diffusing a source or drain region in the surface of one conductivity type semiconductor substrate, coating a thick interlayer insulating film on the entire surface, opening a window, and providing electrodes on the exposed diffused region. CONSTITUTION:A thick interlayer insulating film 13 is coated on a P-type Si substrate 11, a hole 14 is opened, and N<+> type source or drain region 12 is diffused in the surface layer of the exposed substrate 11. Then, when a leading aluminum electrode 16 is coated on the region 12 while extending on the film 13, the electrode 16 is not contacted directly with the region 12, but an extremely thin Si3N4 film 15 of approx. 20Angstrom  is interposed therebetween.

Title: Magnetic storage element
Inventor: OKADA OSAMU
IPC: G11C11/14
Filed: 1982-11-26
Abstract: PURPOSE:To regulate stably bit location of a Bloch line by forming a Bloch magnetic wall around a stripe domain into a wave form. CONSTITUTION:In taking the Bloch magnetic wall around the stripe domain into a wave form viewed vertically to a ferromagnetic film face, the rotation of magnetization in the magnetic wall is smaller than 180 deg. when the Bloch line is at an up part 31 and larger than 180 deg. when at a down part 32, the Bloch lines are gathered easily at the up part 31 and they are parted from the down part 32. Thus, when the shape of the waving form is definite, even if the magnetic wall exists anywhere in the ferromagnetic film face, an equal energy is attained and the regulation of bit location without any action disturbing the transfer is given. As a result, the bit location of the Bloch line is regulated stably without using a magnetostatic force of the Bloch line to a magnetic pole.

Abstract: PROBLEM TO BE SOLVED: To transfer data efficiently by comparing a setting value of block transfer number with a count and controlling DMA transfer of data corresponding to the comparison result. SOLUTION: When data are DMA-transferred from a memory 4 to a device 3 by a DMAC 2, the number of blocks subjected to DMA transfer at once is set to a block number latch circuit 16 of the DMAC 2. Every time a block is transferred from the memory 4 to the device 3, the count of a block number down-counter 17 is decreased and when the count reaches zero, the transfer is finished. A data quantity for DMA transfer is revised dynamically by setting a setting value of the block number latch circuit 16 to an optional value.

Title: Soldering method for semiconductor film
Inventor: FUJISAWA IKUO
IPC: H01L21/52
Filed: 1984-10-04
Abstract: PURPOSE:To provide a means for adjusting the thickness of a solder layer by a method wherein a nozzle is used that blows air upon a semiconductor film. CONSTITUTION:A carrier 1 travels in the arrow-indicated direction, carrying stems whereto semiconductor films are to be soldered. A stem 21 in a first position has a solder layer 3 formed thereon, a stem 22 in a second position has a semiconductor film 4 on the solder layer 3 already molten, and a stem 23 is located under a nozzle 5. A stream of an inert gas comes out of the nozzle 5 to hit the top surface of the semiconductor film 4, pressing the semiconductor film 4 against the stem 23. The molten solder is pushed sideways out of the solder layer 3 and, consequently, the solder layer under the leaf 4 grows thinner. The thickness of the layer to be retained may be adjusted by changing the quantity of the gas jetted out of the nozzle 5 or by varying the distance between the nozzle 5 and the semiconductor film 4.
