Title: Production of mold and core
Inventor: AIGA TOSHIROU
IPC: B22C9/12
Filed: 1980-12-08
Abstract: PURPOSE:To harden molding sand in a short time, shorten gas passing time and improve the efficiency of molding work by putting a molded mold or core mold in an evacuated state and introducing a gaseous substance. CONSTITUTION:Mulled sand 3 molded in a mold or a box 1 is covered with a film 4 and is isolated from the atmosphere, whereby a kind of vacuum chamber is created. The clearances in the sand 3 are evacuated uniformly, after which CO2 is passed and therefore the gaseous CO2 passes uniformly through the sand. Since compressed air is introduced into a pipe 6 during passing of the gas, the CO2 conducted into the mold or box 1 flows in the direction of the pipe 5 and the entire part of the mold or the core reacts with the gaseous CO2 and hardens in a short time; at the same time, the gaseous CO2 escaping into air in an unreacted state is reduced. The similar effect is also obtained when this is adapted to a cold box method.

Title: Recycling method of powdery ion exchange resin
Inventor: NISHIMURA SHIGEOKI
IPC: G21F9/28
Filed: 1980-12-08
Abstract: PURPOSE: To effectively reuse powdery ion exchange resin to be used in an atomic power plant in particular by a method in which a dispersant is added to the slurry of powdery ion exchange resin to which solid particles are adhered and then a supersonic wave is applied to the powdery ion exchange resin to separate the solid particles.  
     CONSTITUTION: Powdery ion exchange resin (referred to as powdery resin) used in the filtration treatment of condensed water in an atomic power plant in particular, in which pressure loss is increased due to the adherence of the solid particles (clad) composed primarily of α-hematite, is subjected to back washng to remove it from a filter element. Then, a clad dispersant composed primarily of a chelating agent (e.g., EDTA) is added to the slurry of the powder resin and then the cladding substance is removed by means of supersonic vibration. Then, the powder resin so treated, having greatly reduced radioactivity, is washed with pure water and then reused in the filtration element for the said filtration treatment. Thus, the amount of radioactive wastes consisting of the powder resin can be reduced.

Abstract: PURPOSE:To perform a low voltage operation by reducing impurity concentration of the lower part of a channel region of an access transistor lower than that of the lower part of a channel region of a driver transistor. CONSTITUTION:A p-well 2 is formed in a semiconductor substrate 1, a field insulating film 3 like an SiO2 film is selectively formed, elements are isolated therebetween, and an insulating film such as an SiO2 film is formed on an active region surrounded by the film 3 by a thermally oxidizing method. Then, an n-type impurity such as phosphorus is ion implanted at the lower part of a channel region by relatively high energy through the insulating film. Thus, the impurity concentration of the well 2 of the lower part of the channel region is reduced. Thereafter, after the insulating film is removed by etching, a gate insulating film 4 such as an SiO2 film is formed on the active region surrounded by the film 3 by a thermally oxidizing method to complete a MOS static RAM.

Abstract: PURPOSE:To lengthen service life of brush by selecting the outer diameter of the brush sliding face of a slip ring regardless of the outer diameter of bearing thereby enabling employment of small diameter slip ring. CONSTITUTION:When a generator is dismantled, brushes 10a, 10b can not be lifted from the outside of a bracket 9 because they are pressed by a slip ring 5, and thereby the brush 10 must be separated from the slip ring 5 while being slided axially and must ride over the outer ring 18 of a bearing 6. Consequently, a guide member 17 having a taper face 16 of such inclination as matching to the difference between outer diameters Ds of brush sliding face and D of the bearing 6 and guiding axial sliding motion of the brushes 10a, 10b while lifting the brushes 10a, 10b radially are provided on a rotor shaft 3 between the slip ring 5 and an adjoining bearing 6.

Title: Semiconductor device for high power
Inventor: MIMURA TAKASHI
IPC: H01L21/3205
Filed: 1979-12-28
Abstract: PURPOSE:To obtain a highly reliable Al electrode of semiconductor for high power by a method wherein an electrode is made by putting an Al layer on a metal layer of large atomic weight which comes in contact with layers of base and emitter, and is extended to the upper part of a protective film, and its side faces are covered with insulators. CONSTITUTION:The deterioration of Al electrode, like the breaking of wire when series of pulses are applied to the electrode, etc., is due mainly to the thermal expansion of electrode irrelevant to current density, and the mean fault time due to the deterioration of electrode is inversely proportional to the coefficient of thermal expansion of electrode metal made in thin film state. Therefore, when Al electrodes 6 are completely covered by covering the upper faces and side faces of Al electrodes on bases 2 and emitters 3 with an insulator 7, and layers 5 of W or Mo, etc., are prepared under the lower face, the thermal expansion of Al electrodes are suppressed forcibly and the deterioration by deformation is remarkably reduced to prevent the deterioration almost semipermanently.
