Abstract: PURPOSE: To integrate a distance measuring scale and a protractor and to reduce the width of the scale by forming holes for depicting a circle in the transparent part of a scale main body and imparting straight line angle indexes of a specified magnification for the distance between holes and also distance makers. CONSTITUTION: Three holes 2 are formed in a scale main body 1 at intervals of about 5cm. Straight line angle indexes 3 for the distance between the holes 2 are obtained from (distance between holes) × 2×sin (angle/2), i.e., 5cm×2×sin (angle/2), or 10cm×2×sin (angle/2). The straight line angle indexes are imparted on the scale 1. The part of the straight line angle indexes 3 is made opaque, and distance markers are imparted on a transparent part.

Abstract: PURPOSE:To separate metal ions continuously and effectively with a single process by feeding a soln. contg. >=2 kinds of metal ions and complex-forming anions to a multi-cell electrolytic cell installed with an anion exchange membrane and/or a cation exchange membrane as diaphragms and proceeding electrolysis in the cell. CONSTITUTION:A cathode 7 and an anode 8 are disposed to an electrolytic cell 1. A cathode chamber 2, an anode chamber 3, and an intermediate chamber 6 are constituted by arranging alternately a cation exchange membrane 5 and an anion exchanging membrane 4 in the order from the cathode side 7 and arranging the membrane 5 to face the anode. A soln. contg. metal ions and complex-forming ions is fed to the electrolytic cell 1 from the intermediate chamber 6, and a soln. of a salt such as NaCl, etc., is fed from the cathode chamber 2 and the anode chamber 3, to proceed electrolysis. Thus, metal cations in the soln. contg. >=2 kinds of metal ions migrate to the cathode chamber 2 through the cation exchange membrane 5. On one hand, metal complex anions migrate to the anode chamber 3 through the anion exchange membrane 4, but metal ions having small ionic characteristic do not migrate and are left in the chamber 6 in undissociated state. Thus, metal ions are separated.

Title: High-frequency dielectric porcelain
Inventor: YAMADA AKIRA
IPC: C04B35/00
Filed: 1988-12-27
Abstract: PURPOSE:To obtain a high-frequency dielectric porcelain with a high dielectric constant and a sufficiently high Q-value in a microwave area by mixing and sintering strontium carbonate, calcium carbonate, and titanium oxide powder into a specific structure. CONSTITUTION:Strontium carbonate, calcium carbonate, and titanium oxide, for example, are mixed and sintered into an Sr3Ti2O7 structure expressed by a formula Sr3(1-X)Ca3XTi2O7, where 0.1<x<=0.55. The dielectric constant is quickly decreased and the realization of the required performance is made difficult if x<=0.1 outside of this composition range. If x>0.55, the Sr3Ti2O7 single-phase structure collapses, the dielectric constant is increased but the Q-value is decreased in this area where multiple phases start to be generated, the V-value is made lower than 1000 in 9GHz, and the required characteristic can not be satisfied. A high-frequency dielectric porcelain with a dielectric constant higher than 80 and a sufficiently high Q-value of 1000 or above in the microwave area can be obtained.

Title: Method and device for detecting inclination of document image
Inventor: KAWANAKA SEIDO
IPC: G06K9/32
Filed: 1989-12-19
Abstract: PURPOSE:To detect the inclination of a document image at a high speed by a simple processing by converting a background component of a character-string to a fine line, and deriving an inclination of the obtained fine line. CONSTITUTION:When a background component of a character-string is converted to a fine line in a document image, background components between the character-string and the character-string, and between a character and a character are converted to a fine line. In this case, for instance, in 'D' and 'O', the background part surrounded by a stroke component, that is, a hole degenerates automatically. The fine line between the character-string and the character-string, that is, between a line and a line is longer than the fine line between the character and the character contained in each character-string, therefore, by using it as a feature, the fine line between the line and the line can be extracted. In such a way, by deriving an inclination of this fine line, an inclination of the character-string can be derived approximately.

Filed: 1997-12-02
Abstract: PROBLEM TO BE SOLVED: To improve the opening property of a scoring part and the safety after opening a can by forming a score part of an open end with pre-shearing from one direction and with return shearing from the reverse direction. SOLUTION: In the score part formed with pre-shearing from one direction and with return shearing from the reverse direction after then, in the time of opening, crack is advanced with the stress concentration caused on acute notches existing on front and back faces. Because a central part to be advanced with the crack is already received with large repeat shearing strain even without generating breaking, the ductility of the material itself is reduced and the crack is advanced easily. Further, in the final shear breaking position (burr generating position), because it is positioned at inner part in the wall thickness direction against the original metal sheet, the ductility of the material is inclined to reducing, so a large burr is not generated, in consideration of the state of generation, the anxiety of a cut of hand or finger, etc., is nothing in the real using.
