Title: Method and apparatus for concentrating methane by making use of paper-manufacturing waste water evaporation-condensate
Inventor: MINAMI SEIJI
IPC: C02F3/28
Filed: 1985-06-22
Abstract: PURPOSE:To enable methane gas to be concentrated without an increase in cost by contacting the generated gas in a fermentation process with the paper-manufacturing waste water evaporation-condensate, by dissolving CO2 and H2S present in the generated gas into the condensate to make a solution and by feeding said solution in a pretreatment process. CONSTITUTION:The titled method comprises a pretreatment process and a methane fermentation process. In the pretreatment process, an acid is added into the paper-manufacturing waste water evaporation-condensate to lower the pH up to <=3, the methane fermentation- inhibiting substance is precipitated, flocculated and removed, and the waste water is then neutralized. In the methane fermentation process, the pretreated waste water is allowed to flow into a fermentation bioreactor to treat the waste water and to produce methane gas. In the methane-concentrating method of the methane fermentation treatment, the above- mentioned paper-manufacturing waste water evaporation-condensate is contacted with the gas generated in the above-mentioned fermentation process to dissolve CO2 and H2S present in the generated gas into the condensate, which is fed to the above-mentioned pretreatment process to concentrate methane gas. Thus, the concentration of methane in the gas generated from the paper-manufacturing waste water evaporation-condensate can be increased without increasing the cost.

Abstract: PURPOSE:To decrease hardware and to attain efficient information exchange between a master and a slave set by allowing the master and the slave set to use an information storage register in common and exchanging the information between both the sets at a prescribed period. CONSTITUTION:The master set 1 checks the content of a display register 4, i.e., whether or not the display register 4 is set via an identification line 6 at a prescribed period. When the display register 4 is set, the master set 1 fetches the content of an information storage register 3, i.e., the information to be transmitted from the slave set 2 to the master set 1 via an information transfer line 8.

After the slave set 2 detects this interruption, the content of the information storage register 3 is fetched via an information transfer line 7. After the slave set 2 stores this information to the information register 3 via the information transfer line 7 when the information to be transmitted to the master set 1 exists, the slave set 2 sets a display register via an access line 5 and awaits the next interruption from the master set 1.

Title: Switch circuit
Inventor: DOBASHI NAGAYOSHI
IPC: H03F3/181
Filed: 1999-05-18
Abstract: PROBLEM TO BE SOLVED: To improve frequency characteristics in a high-frequency area by reducing the crosstalks of a switch. SOLUTION: In this switch circuit, when SWb1 is closed, a video signal applied to INb1 is outputted from an output terminal OUTb through the collector of a transistor(TR) Qb1, the emitter of the TR Qb1, the base of a TR Qb2, the emitter of the TR Qb2, and the base of a TR Qb5 in this order. When SWb2 is closed, a video signal applied to INb2 is outputted from an output terminal OUTb as well. Consequently, a line Lb can be constituted having low impedance and the video signal is outputted by using an emitter follower circuit, so the crosstalks is reduced to obtain excellent frequency characteristics.

Filed: 1979-10-26
Abstract: PURPOSE:To form a electrode wiring excellent in ohmic contact property and adhesivity by continuously applying a silicon film and a silicide film of a high- melting-point metal in such a manner that the surface of a silicon film is kept from being exposed. CONSTITUTION:A silicon is evaporated on a silicon substrate 1 having a contact hole formed therethrough for a given time. Then, a high melting-point metal is deposited on the substrate 1 continuing the silicon evaporation to form a laminated film of a silicon film 5 and silicide film 6 of a high-melting-point metal. Consequently, a silicon film 5 is interposed between the silicon substrate 1 and the silicide film  6. Though exisiting on the substrate of the silicon substrate, a silicon oxide 3 of  20- 30Angstrom  is easily taken into a crystaline particle mass of the silicon film by heat  treatment as it is pinched between the same kind of semiconductors like the silicon  substrate 1 and the silicon film 5. Accordingly, a better ohmic contact can be  obtained.

IPC: G11B5/127
Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To provide a constitution for suppressing increase in external induction noise and cost even if a track width is increased in a magnetic head. SOLUTION: In a magnetic core 1, nearly U-shaped sides of core half bodies 1a and 1b formed in nearly U-shape are mutually jointed through a spacer 3 to be formed into a nearly square shape for forming a magnetic gap.
