Title: Formation of contact in superconductive circuit
Inventor: NAKAGAWA HIROSHI
IPC: H01L39/24
Filed: 1985-06-03
Abstract: PURPOSE:To contrive the exceeding improvement in the characteristics as of a contact which are obtained at last by adding a step of dry etching of the surface of Nb layer by using of carbon fluoride gas and a step of exposing the surface to a sputtering environment of nitrogen gas. CONSTITUTION:On an Si substrate 10, an Nb layer 11 as a superconductive layer which will become a ground plane of a predetermined pattern is formed over the approximately entire surface, after which dry etching by use of carbon fluoride gas CF is done before the patterning process. After this step, it can be regarded that the condition that the carbon atoms C enter into a surface layer of the remaining Nb layer is generated. Following this carbon fluoride treatment step, the introduced gas in the high-frequency sputtering device is changed to nitrogen gas N and the surface layer of Nb layer 11 is exposed to that sputtering environment. As a result, a nitrogen atoms N are regarded as also implanted into the surface layer of Nb layer 11 further. Accordingly, the surface layer of Nb layer 11 can be considered to become an inert layer 23.

Title: Temp. control of substrate, substrate heat treating apparatus and substrate supporting apparatus
Inventor: HISAI AKIHIRO
IPC: H01L21/027
Filed: 1996-05-15
Abstract: PROBLEM TO BE SOLVED: To control the temp. of a substrate at high accuracy for a short time by the temp. control of a substrate support table with heating and cooling by a heat exchanger in a temp. control process. SOLUTION: While a hot plate 16 is conditioned e.g. at 110 deg.C, a substrate W at the room temp. is fed onto a substrate support plate 30 of a plate 16 to result in a rapid temp. drop of the plate 16. If the output of a temp. detecting sensor 40a indicates the temp. of the plate 16 drops more than e.g. 0.5 deg.C, the main controller 44 controls a first temp. controller 41 so as to feed a max. allowable current to an auxiliary heater/cooler 31. As the result, the temp. of the plate 16 rises at full power. When the plate temp. reaches 110 deg.C, the controller 44 switches the controller 41 to a PID control to slow down the temp. rise and control the substrate temp. at e.g. 110 deg.C±0.3 deg.C by heating and cooling.

Title: Production of target for sputtering
Inventor: YAMAGISHI TOSHIHIKO
IPC: C23C14/34
Filed: 1986-05-26
Abstract: PURPOSE:To prevent the unstable state of plasma arising from the crack of a target for sputtering having the compsn. of an intermetallic compd. in the stage of sputtering by bonding the target to a backing plate then applying thermal impact thereto to preliminarily crack the target at the time of producing the above-mentioned target. CONSTITUTION:The target for sputtering of the compsn. consisting of the intermetallic compd. contg. plural metallic elements is bonded to the copper backing plate at the time of producing said target. Such target is then heated and the thermal impact is applied thereto by sprinkling liquid nitrogen thereon to induce the cracks therein. The target is already cracked at the time of executing sputtering by using such target and therefore, the formation of the fresh cracks by the thermal impact during the sputtering is obviated. The generation of the instantaneous instability of the plasma when the target cracks is thereby obviated and the film formation by the target is executed in conformity with specifications.

Abstract: PURPOSE:To extract a medicinal component from a culture mixture of mycelium at low cost. CONSTITUTION:A medicinal component is obtained from a process of cultivating a mycelium belonging to Basidiomycetes (e.g. Lentinus edodes, Pleurotus ostreatus, Flammulina velutipes, Pholiota nameko, Lyophyllum aggregatum, Coriolus versicolor or Polyporaceae) in a solid medium (e.g. bagasse medium or beet refuse medium), a process of grinding the culture mixture of mycelium in a completely aged state cultivated by the culture process, a process of aerating, heating and drying the ground culture mixture of mycelium obtained by the grinding process at about 80 deg.C for 3-4hr and a process of extraction by boiling the culture mixture of mycelium obtained from the aerating, heating and drying process. Since self digestion of the mycelium is promoted by aerating, heating and drying the culture mixture of mycelium as above-mentioned and finally the mycelium is deactivated, there is no fear of occurrence of decomposition even if the culture mixture of mycelium is temporarily stored and the medicinal component can be extracted at low installation cost and at low cost without requiring a large-sized preserving chamber in cold storage.

Abstract: PROBLEM TO BE SOLVED: To properly adjust a startup, a stoppage and an increase or decrease in replenishment water volume so as to cope with the increase or decrease of a demand by applying the constitution that intake water from an existing water collecting and intake facility is stored in an underground hollow dam constructed by excavating a large hollow part within an underground subsoil including a water infiltration retarding layer, and water is fed to a demanding part whenever necessary. SOLUTION: Large hollow space is excavated in an underground bedrock 10 including a water infiltration retarding layer and an underground hollow dam 8 is thereby constructed. Furthermore, intake water from an existing water collecting and intake facility 12 such as a pumping station 16 for a river, a well or the like, an intake port 18 for a river and an upstream ground hollow dam 8 is introduced to an underground hollow dam 18 for storage via a water introduction passage 22. Then, stored water in the underground hollow dam 8 is fed to a purifying facility 14 from a pump 24 via a water supply passage 26, and distributed to each home 32 from a water distribution facility 28. In this case, the dam is located underground and the stored water does not evaporate or dissipate, and underground water infiltrates and flows to the hollow space from a bedrock.  As a result, a water volume increases and the stored water can all be used effectively. Also, necessary action can be taken against a draught water flow by storing fresh water, under the implementation of a startup, a stoppage and adjustment for an increase or decrease in replenishment water volume, so as to cope with an increase or a decrease in demand.
