Title: Air-fuel ratio control device for internal combustion engine
Inventor: NISHIMOTO KYOTARO
IPC: F01N3/08
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To quickly change air-fuel ratio by connecting piping between a mixer and an engine to a fuel gas feed pipe on the upper stream side of an air-fuel ratio control valve through a bypass pipe interposed with an opening/closing valve, and making a detour of the miser and the air-fuel ratio control valve to feed fuel gas. SOLUTION: A piping 11 between a mixer 2 and an engine 1 is connected to a fuel gas feed pipe 6 which feeds fuel gas to air-fuel mixture through a bypass pipe 5 interposed with an opening-closing valve 13. This fuel gas feed pipe 6 is branched into pipings 8, 9 at the branched part 6a on the way, an air-fuel ratio regulating valve 7 is interposed on the way of one piping 8, and an air-fuel ratio control valve 4 driven by an electric step motor 3 is interposed on the way of the other piping 9. Both pipings 8, 9 are joined together at a confluent part 6b, and then connected to the mixer 2. When excess air factor (air-fuel ratio) is changed from the lean side to the rich side, or from the rich side to the lean side by opening the opening-closing valve 13, the air-fuel ratio is changed quickly.

Title: Apparatus for producing magneto-optical recording medium
Inventor: INOUE DAISUKE
IPC: C23C14/46
Filed: 1987-04-15
Abstract: PURPOSE:To permit reduction in the time for production without generating contamination by providing a magnetic film target to be used for forming a magneto-optical recording film and shielding film target to be used for formation of a shielding film and disposing both targets selectively freely usably. CONSTITUTION:The magnetic film target 13 and the target 12 consisting of Si to be used for forming the shielding film 5 are provided in a film forming chamber 82 for forming the magneto-optical recording film 3. Both the targets 12, 13 are freely selectively used. The dielectric film is transferred, after the formation, into the film forming chamber for forming the magneto-optical recording film, where the shielding film target is selected and the first shielding film is formed on the surface of the dielectric film. The magnetic film target is then selected and the magneto-optical recording is formed on the surface of the first shielding film. The shielding film target is again selected and the next shielding film is formed on the surface of the magneto- optical recording film by this target. The film is transferred to the ensuing film forming chamber for a protective film in succession thereto and the protective film is formed thereon. Contamination is thereby prevented and the reduction in the time for production is permitted.

Title: Screw type fluid machine
Inventor: UCHIDA RIICHI
IPC: F04C18/16
Filed: 1990-04-09
Abstract: PURPOSE:To generate high pressure gas and vacuum simultaneously by a single machine, by making one side pair of screw rotors function as a compressor, and the other side pair of screw rotors function as a vacuum pump. CONSTITUTION:Two pairs of screw rotors 5a, 6a and 5b, 6b geared each other are formed around two rotation shafts 5 and 6. And each pair of screw rotors 5a, 6a and 5b, 6b are housed in casings 1 and 3, and the casings 1 and 3 are made unitary. As a result, when the rotation shafts 5 and 6 are rotated reversely each other, the screw rotors absorb the gas from a suction port 15 and exhaust from an exhaust port 13 to the atmosphere, and thereby, function as a vacuum pump. On the other hand, the screw rotors 5b and 6b absorb the atmosphere from an air suction port 14 and exhaust a compressed air from an exhaust port 16, and thereby, function as a compressor. Consequently, high pressure gas and a vacuum can be generated simultaneously by a single machine, and a space saving of the machine is realized.

Title: Control device for air conditioner
Inventor: KOYAMA YOSHIMASA
IPC: F25B49/02
Filed: 1983-05-27
Abstract: PURPOSE:To reduce a frequent repetition of start and stoppage of a compressor so as to improve its durability by so constructing that once a motor for the compressor is stopped, it will not start for a certain period of time even if a command to start is output. CONSTITUTION:A timer 12 exclusive for starting has a time limit reverse contact point 12b that opens a circuit after a certain elapsed time from being electrified, and a timer 13 has a time limit contact point 13a that closes a circuit after a certain elapsed time which is set shorter than that for the timer 12. When a thermostat 6 is openend while in a cooling mode, a contact point 3a is opened to shut down a compressor 1, and at the same time, a normally closed point 3b is closed to electrify the timer 13, but a normally opened contact point 13a is opened for a certain duration. Even when the thermostat 6 is closed thereafter, since the time limit contact point 12b and the normally opened contact point 13a are both opened, the compressor remains to be stopped. The timer 13 closes its time limit contact 13a after a certain period of time from being electrified to energize a relay for the compressor to open its normally opened contact point 3a so as to start the compressor motor 1 and to close the normally closed contact point 3b.

CONSTITUTION:Conjoining planes orthogonal respectively to their corresponding orientation planes are opposed together at a space therebetween, then fine powder 2 made of the same construction material as a superconductor and yet being justified in regarding the powder substantially as a monocrystal is filled into the space, a magnetic field H in a direction vertical to each of the orientation planes is applied to the conjoining portion centering on the fine powder-filled portion, and the fine powder-filled portion is heated and sintered while pressurizing it in its bilateral directions reducing the space filled with the fine powder 2. Each superconducting wire-rod 1 further has 'each two-dimensional reticulate plane consisting of a Cu ion and an O ion in its unit cell'. Also the fine powder 2 made of an oxide superconducting material (the same material as each superconducting wire-rod 1 forming a main body) is required to have grading of such an extent as being justified in regarding substantially as a monocrystal. The same superconductivity as the main body can thus be given to the conjoining portion for putting each wire-rod made of the oxide superconducting material to practical use.
