Title: Dry plate for exposure
Inventor: AKUTAGAWA SATORU
IPC: G03F1/00
Filed: 1988-03-14
Abstract: PURPOSE:To improve resolution of transferred pattern by an exposure with reflected light by providing a filter film, which reduces wholly or partly reflectance of a transparent base plate, onto a surface of a metallic film for forming a pattern formed on a surface of the transparent base plate. CONSTITUTION:Irradiating light from a light source 24 is made incident onto a dry plate for exposure through a half mirror 25, and reflected light is made incident onto a base plate 26 for exposure after being reflected by the half mirror 25. Thus, a photosensitive material 27 is sensitized and a pattern is transferred. When a filter film 23 for reducing a reflectance is provided onto a Cr film 22 for forming the pattern on the surface of the dry plate for exposure, the reflected light at this part is made less intense than the reflected light from a glass base plate 21. Thus, a contrast between the reflected light from the base plate 21 and the reflected light from the film 23 is enhanced. Further, the shape of a pattern transferred to the base plate 26 becomes equal to the shape on the film 23. Thus, a resolution of a pattern transferred onto the base plate is improved.

CONSTITUTION:The optical film thickness of the film layers B1, B31 deposited by evaporation of high refractive indices is made to 0.16 wavelength thicker than 0.125 wavelength of the central wavelength of vapor deposition and thinner than 0.2 wavelength and the ripple wave for a P polarized wave is made min. The optical film thickness of part of the whole of the other vapor deposition films having high refractive indices except the 1st layer and final layer mentioned above is made thicker than 0.25 wavelength which is the central wavelength of vapor deposition and thinner than 0.4 wavelength and the optical film thickness of part or the whole of the vapor deposition film having low refractive indices mentioned above is made thinner than 0.25 wavelength which is the central wavelength of vapor deposition and thicker than 0.15 wavelength. The film thickness of, for example, film layers B2 and B30 deposited by evaporation is made 0.17 wavelength, B3 and B29 0.28 wavelength, B4, B6 and B26, B28 0.2 wavelength, B5 and B27 0.3 wavelength and from B7 up to B25 0.25 wavelength. The respective films deposited by evaporation are made successively symmetrical above and below so as to decrease the ripple of the pass band for the P polarized wave in the above-mentioned way, by which the ripple for the P polarized light is minimized.

Title: Production of basic refractory and the refractory
Inventor: GOTO KIYOSHI
IPC: C04B35/043
Filed: 1995-02-24
Abstract: PURPOSE: To produce an inexpensive basic refractory high in service property. CONSTITUTION: Refractory material A comprising at least magnesia and titanic iron ore B is used as a starting material, and the starting material is mixed so that the relation of a compounded amount ((x)wt.%) of the A and the compounded amount ((y)wt.%) of B in total compound satisfies the following formula (1). 50<=x<=99. 1<=y<=40...... (1). (x)+(y)<=100. In this way, a refractory high in corrosion resistance is obtained because a compd. formed by a reaction of a titanium oxide component in the titanic iron ore with magnesia suppresses the infiltration of a slug at the time of burning or using of the refractory. A resistance to thermal shock is also improved by a change in the structure of the refractory caused at the time of reaction. On the other hand, the refractory high in service property is produced inexpensively since the titanic iron ore is inexpensive.

IPC: F25B1/00
Filed: 1978-05-19
Abstract: PURPOSE: To perform proper cooling effect over the full revolution range of a compressor by branching a main coolant circuit between a condenser and an  evaporator and forming an injection circuit with a coolant controller to be connected to a capacity control compressor.  
     CONSTITUTION: An injection circuit is so formed as to connect the middle part between a condenser 2 and a main circuit decompressor 3 to a revolution control compressor through a flow rate controller valve 5. Thus, following the frequency change at a bridge inverter control circuit according to the load, the revolution number of the compressor also changes. Therefore, according to the degree of load, a controller H controls the flow rate controller valve to be open or closed so as to increase or decrease the amount of injection. Thus, the injection amount is controlled in proportion to the revolution number of the revolution control compressor 1, always obtaining-proper cooling effect.

Title: Method for detecting center of band-shaped sample
Inventor: TAKAHASHI HARUO
IPC: G01B15/02
Filed: 1993-03-19
Abstract: PURPOSE:To improve the measuring reliability by roughly scanning/measuring an area where data are present, calculating a virtual center of a sample from the result, collecting further data based on the virtual center, calculating the center of gravity from the collecting data, and making corrections. CONSTITUTION:The neighborhood of a band-shaped sample or area is scanned/measured every rough interval. The intensity of X rays at a point where the intensity becomes maximum and at two points at both sides of the point is obtained. The range is divided by an average value for the data of three points. If the range/average is close to 3.0, it is so judged that the maximum value catches the vicinity of the center. Unless the range/average is close to 3.0, it is so determined that the maximum value is detected in the vicinity of an edge. Accordingly, the maximal point is set as a virtual center. Then, the intensity of X rays is obtained for five points, i.e., the virtual center and every two points at both sides of the virtual center every half the interval at the first scanning time. The center of gravity is obtained from the data of five points. A data decided not to be related to the sample or area is removed based on the distance from the center of gravity, and the center of gravity is operated again. Two points presumed to be in the vicinity of the edge based on the calculated center of gravity are measured and added, which is determined as the center of gravity of the sample or area.

Abstract: PROBLEM TO BE SOLVED: To prevent a voice coil from being burnt even when a DC current flows to the voice coil by providing a cylinder, which is formed from the metal of low permeability facing close the outer periphery of bobbin, on a top plate. SOLUTION: A ring (cylinder) 2 made of the metal (such as aluminium alloy, for example) of extremely low permeability fixed by an adhesive agent or the like is provided on a top plate 13. On the other hand, when an excessive DC voltage is impressed to a voice coil 14 because of any fault on an amplifier, etc., heat generated at a position upward deviated from the prescribed position of voice coil 14 is radiated by the ring 2 arranged proximately to the voice coil 14. Then, the radiated heat is transmitted to the contact top plate 13 and frame 18 and radiated from a wide surface area into the space so that the temperature rise of voice coil 14 is suppressed and the danger of burning (disconnection) is eliminated. Besides, since the permeability of ring 2 is extremely low, there is no change in a magnetic field and the operation of speaker is not affected at all.
