Title: Cryogenic cooling device
Inventor: ONO MICHITAKA
IPC: G12B15/02
Filed: 1988-06-22
Abstract: PURPOSE:To separate a shield from a refrigerator mechanically and prevent the vibration of said refrigerator from being directly transmitted to a vacuum vessel by producing a vacuum chamber different from a vacuum layer of a vacuum vessel around a support member, pulling out the end of said support member to an ambient temperature section, and providing a buffer, such as bellows between said refrigerator and vacuum vessel. CONSTITUTION:When it is necessary to replace an O ring or the like, loosen studs 17 and 18, which serve as a connection member 19 and move upward those which are integrated with a refrigerator 1, a cylinder 13, and a low temperature generation section and remove the low temperature generation section from a heat conductor 15. Then, a second bellows 21 which is a second buffer as well as a refrigerator's airtightness holding member is elongated, thereby preventing a vacuum state in a vacuum chamber 22 from being broken. When the refrigerator 11, the cylinder 13, and the low temperature generation section 14 are disassembled for repair, remove a bolt 29 and a nut 30 and the aforesaid members 11, 13 and 14 from a support member 5, then start the work. The refrigerator 11 is fixed with a shield 4 while a vacuum vessel 2 is connected in such a manner that no vibration of the refrigerator may be transmitted, maintaining the vacuum state by way of a first bellows which is a first buffer.

Title: Method for controlling air-fuel ratio of internal combustion engine
Inventor: TANAKA MASAJI
IPC: F02D41/14
Filed: 1988-06-22
Abstract: PURPOSE:To prevent the increase in the quantity of NOx by increasing the electromotive force value of an oxygen sensor for judging the theoretical air-fuel ratio at the time when the period for judging an air-fuel ratio to be in a condition of richer fuel than the theoretical air-fuel ratio gets longer. CONSTITUTION:The correction of a judging voltage for increasing the voltage value for judging a theoretical air-fuel ratio by means of an O2 sensor 5 in accordance with the sulfur content of a using fuel when a rich residence time gets longer is carried out in a control system 2. If the rich residence time in which SO2 is contained in an exhaust gas becomes longer, the response time of the O2 sensor 5 at the time of changing from a rich condition to a lean condition gets longer, causing a feedback control to judge to be a rich condition in spite of the lean condition of air-fuel ratio, to control air-fuel ratio to be a lean condition. Hence, the time of detecting the lean condition from a rich condition by means of the O2 sensor 5 is reduced to prevent the delay in response of the O2 sensor 5.

Filed: 1988-06-21
Abstract: PURPOSE:To demultiplex a light beam of arbitrary wavelength by making the wavelength obtained from a second waveguide continuously variable by applying a voltage between electrodes. CONSTITUTION:In case a reflecting layer having a small refractive index n2 and the second waveguide layer having a large refractive index n1 are laminated successively on a first waveguide having a large refractive index n0, and a diffraction grating of a period LAMBDAg has been formed in an interface of the second waveguide and the reflecting layer, only a light beam of wavelength lambda1 for satisfying an expression I is diffracted. In case the second waveguide has been formed by a superlattice layer, forbidden band width Eg of the second waveguide decreases by a quantum Stokes effect by applying a voltage to said superlattice layer, and as a result, the refractive index n2 of the second waveguide increases and becomes n3, and wavelength of a diffracted light is varied as lambda3 of an expression II. In such a way, by applying a voltage to the superlattice layer which has constituted the diffraction grating and varying the refractive index, a light beam of arbitrary wavelength can be demultiplexed.

Title: Gas injection nozzle to be used for atmospheric soldering
Inventor: KAWAKATSU ICHIRO
IPC: B23K1/08
Filed: 1994-06-02
Abstract: PURPOSE:To prevent adherence of melted solder to a nozzle port by using a nozzle of titanium or titanium alloy instead of stainless steel as an inert gas injection nozzle. CONSTITUTION:A plurality of nitrogen gas injection nozzles 6 are provided perpendicularly to a main tube 5. A printed board is directed to a position separated from melted solder, and installed in parallel on an axis perpendicular to a screen. Nitrogen gas is injected to a separator, and the vicinity of the separator is excellently soldered Thus, the nozzles 6 perform important role, but there is a danger of blocking the nozzle ports by the adherence of the solder. Then, it is improved by using a titanium pipe instead of stainless pipe of SUS304. Since the titanium is activated metal and a rigid and stable oxide film is formed on the surface, if melted solder is adhered, it repels the solder, i.e., and is scarcely 'moistened' with the solder.
