Abstract: PURPOSE:To enable atoms or molecules to be disposed in a line or spots on the surface of a solid substrate, by a method wherein a step configuration including a corner section is formed on the surface of the solid substrate by etching or film formation, and an atomic layer or a molecular layer is then formed on the surface, and thereafter an atomic line or an atomic spot, or a molecular line or a molecular spot is formed in the corner section of the step configuration by heating. CONSTITUTION:A step configuration including a corner section 2 is formed on the surface of a solid substrate 1 by etching or film formation, and an atomic layer 3 or a molecular layer is formed on the surface of the substrate body. Thereafter, an atomic line 5 or an atomic spot, or a molecular line or a molecular spot is formed in said corner section 2 by heating the substrate body. For example, a step configuration including a corner section 2 is formed on the surface of a solid substrate 1 of a single crystal silicon or the like by a photo-etching process, or by partially forming a silicon film or a silicon oxide film. Subsequently, an atomic layer 3 or the like, which is made up of antimony atoms or gallium atoms, or single atoms or single molecules of compounds or macromolecules, is formed on the surface of the solid substrate 1 including said coner section 2. Next, the substrate body is heated at a higher temperature than the formation temperature of the atomic layer 3 or the like to dissociate the atomic layer 3 or the like, and thereby an atomic line 5 or the like is formed in the corner section 2 of the step configuration.

Abstract: PURPOSE:To provide a welding power source which shortens the time width of a negative polarity and decreases loss, by connecting DC reactors in series as a DC constant current source which does not switch to the positive pole side and using a DC constant current source which switches to the negative pole side. CONSTITUTION:A DC constant current source 2 on a positive pole side is connected in series to DC reactors L1, L2 in an electric power source of AC arc welding.

The current flowing to the load 1 is commutated to the pulse circuit side and the pulse current by the current 2 flows if the TR T3 turns on. The TR T3 turns off when the pulse current attains the set value. The power source device which is in a short time at the negative polarity as compared to the positive polarity and has a decreased loss is realized by such circuit constitution.

Title: Air conditioner
Inventor: KADOWAKI KAZUHIKO
IPC: F25B29/00
Filed: 1990-03-07
Abstract: PURPOSE:To facilitate the closing operation of an automatic switching valve executed by a shape memory member and to close the automatic switching valve more reliably in a short time by making a refrigerant flow also through a bypass piping in a dry operation, by stopping both outdoor and indoor fans in this operation and by reducing further thereby the lowering of a temperature due to condensation of the refrigerant. CONSTITUTION:In a cooling operation, a gas refrigerant is condensed in an outdoor heat exchanger 6, while it is evaporated in first and second indoor heat exchangers 10 and 11. Since a refrigerant of low temperature is supplied to an automatic switching valve 14 on the occasion, the automatic switching valve 14 opens and the refrigerant passes through this valve, not passing through a pressure reducing mechanism 13. In a dry operation, on the other hand, a switching valve 21 is made open by a valve opening means 27 and therefore the refrigerant flows also through a bypass piping 20. Since a refrigerant passage before and behind an expansion mechanism 8 is increased by the bypass piping 20, the flow of the gas refrigerant of high temperature is facilitated. Since a fan stopping means 26 stops both outdoor and indoor fans 15 and 16, the lowering of the temperature of the refrigerant is further reduced. Therefore the closing operation of the automatic switching valve 14 by a shape memory member 17 is facilitated and thus the automatic switching valve 14 is closed in a short time.

Title: Method for measuring wave front shape
Inventor: KITABAYASHI JUNICHI
IPC: G01B9/02
Filed: 1985-03-20
Abstract: PURPOSE:To enable highly accurate measurement simple to remove the effect of vibration or temp. change, by correcting the variation in the mutual lateral shifting distance between measuring light beams separated into two luminous fluxes incident to an area sensor in a real time. CONSTITUTION:An optical system consisting of a beam splitter 10 and flat mirrors 12, 14 splits measuring light into two luminous fluxes mutually inclined by a minute angle theta in an xy-plane predetermined in its advance direction. These two luminaus fluxes are incident to an area sensor 16 in a state laterally shifted by a minute distance S in the above-mentioned xy plane to generate an interference fringe on the sensor 16. This interference fringe is read by the sensor to receive Fourier transform. An inclination component is removed from the result of Fourier transform to receive inverse Fourier transform. Predetermined operation containing the integration in the lateral shift direction is applied to the phase difference known from the result of inverse Fourier transformation and the shape of a measuring wave front is obtained.
