Title: Superconducting electrical device
Inventor: HAYASHI SHIGEAKI
IPC: H01F6/04
Filed: 1989-10-27
Abstract: PURPOSE:To acquire super-cooled liquid nitrogen only in an inner tank by providing an expansion valve and a heat exchanger in refrigerant of a refrigerant tank which is pressurized to an atmospheric pressure or higher and by discharging a part of refrigerant outside through them. CONSTITUTION:A superconducting transformer which is composed of a core 1, a low pressure winding 2 and a high voltage winding 3 using an oxide super conductor is cooled by liquid nitrogen 7 of a tank 4 which is pressurized to an atmospheric pressure or higher. A part of the liquid nitrogen 7 is depressurized by an atmospheric pressure by an expansion valve 10 and is discharged to atmosphere through a heat exchanger 11. At this time, the tank 4 is cooled to an atmospheric pressure liquid nitrogen temperature of 77.36K. That is, since the liquid nitrogen 7 of the tank 4 is super-cooled, deterioration of insulation strength can be prevented without development of bubbles from the liquid nitrogen 7 even if temperature-up is caused by heat generation of the low pressure winding 2 and the high voltage winding 3.

Title: Scan stage device and scan-type aligner
Inventor: SAKAMOTO EIJI
IPC: G03F7/20
Filed: 1996-10-04
Abstract: PROBLEM TO BE SOLVED: To reduce scan stage length measurement error in laser interferometer method, for improved positioning precision by allowing an air-conditioning wind speed from a blast means which blows a temperature-controlled air current to a scan stage to be faster than a moving speed of the scan stage. SOLUTION: A blow-off opening of an air-conditioning means 28 is connected to a blast channel 41, and a scan stage 4 is provided in its air conduit 41. With the blast channel 41, the cross-section area of the air path is changed in succession, and the wind direction of air-conditioning air is made nearly in scanning direction on length-measurement light path. Here, the flow speed (wind speed) of air current 30 blown out of the air-conditioning means 28 on a length- measurement light path 25 is set to be about 0.2m/sec, being faster than scanning speed (= about 0.1m/sec) of the stage 4.  In this case, all the air around a linear motor 27 is blown to ahead of scanning direction of the reticule stage 4, so that the air on the laser length-measurement light path 25 is just the one blown out of the air-conditioning means 28, resulting in temperature-fluctuation less than 0.1 deg. which is very small.

Title: Matrix exposure type printing head
Inventor: NODA MASAYOSHI
IPC: G02B27/00
Filed: 1987-11-10
Abstract: PURPOSE:To accelerate printing speed and realize structural simplification, compactness and weight reduction by applying voltage to the first and second transparent electrodes, making the intersection point of both electrodes light-permeable, allowing a beam from a light source to penetrate through a matrix to be made a parallel beam by a refractive index distribution lens, and condensing the parallel beam to a single point using a condensing lens. CONSTITUTION:Voltage is applied to the first and second transparent electrodes 6, 8, the intersection of which corresponds to a specific matrix 12. Consequently, a beam from a light source penetrates through a liquid crystal element 4 in the part of the intersection point. This penetrating beam is introduced into a refractive index distribution lens 15, and an outgoing beam is entered into a condensing lens 16 as a parallel beam flux L2. As a result, the flux is condensed to a single point by means of the condensing lens 16 to form an image. This imaging point (s) becomes the same point in all the matrices 12 by condensing function of the condensing lens 16. Consequently, a static latent image is formed in the charged portion of the periphery of a photosensitive body at the imaging point (s). A static latent image is formed in a main scan direction by executing the image formation while a carrier is moved. The matrix 12 can be selected by controlling voltage application to the first and second transparent electrodes 6, 8 without movement of a character dial 3 and thus printing seed can be accelerated.

CONSTITUTION:A Langmuir-Blodgett thin film comprising a high mol.wt. compound is intermediately provided as a spacer between Langmuir-Blodgett monomolecular films comprising molecules of a coloring matter. A thin film of a high mol.wt. compound in an organic thin film is required to be extremely thin and be uniform, not only for accurate control of the spacing between the molecules of the coloring matter but for stacking a plurality of layers of such a structure and converting a film with a large are into a minute element. For fulfilling the requirements, Langmuir-Blodgett thin films of a high mol.wt. compound formed by the Langmuir-Blodgett method are most suitable. With this organic thin film, the spacing between the monomolecular films comprising the molecules of a functional coloring matter can be controlled by the thickness (about a few to 20Angstrom ) of the monomolecular film of the high mol.wt. compound, so that control of function can be performed extremely easily.
