Title: Method and instrument for measuring shape of surface to be measured
Inventor: NAGAHAMA HIROYUKI
IPC: G01B11/24
Filed: 1992-02-27
Abstract: PURPOSE:To two-dimensionally find the shape of a surface to be measured with high accuracy by finding the whole shape of the surface to be measured by composing surface forming components except the curvature component obtained in a first measuring process and the curvature of the surface to be measured. CONSTITUTION:Two luminous fluxes reflected by a reference plane 51 and surface 61 to be measured advance in the opposite direction while the luminous fluxes interfere with each other and are reflected by a beam splitter 3. After reflection, the luminous fluxes are led to an image pickup element 8 through an image forming lens 7. Image signals based on interference fringes obtained by means of the element 8 are inputted to an arithmetic and control section 9 and the section 9 calculates the interval between the plane 51 and surface 61 based on the distribution of the interference fringes. In a first measuring process, the curvature component K(X<2>+Y<2>) of the shape of the surface 61 is calculated. In a second measuring process, the component WA-PO(X, Y) of the surface shape of the surface 61 other than the curvature is calculated. Then when WA(X, Y)=K(X<2>+Y<2>)+WA-PO(X, Y) is calculated, the two-dimensional shape WA(X, Y) of the surface 61 is finally found.

Title: Motor
Inventor: KAWAZOE KAZUSHIGE
IPC: F16C17/10
Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To seal a fluid for a bearing in a bearing cylindrical body without using a magnetic fluid. SOLUTION: A shaft 16 is inserted into the cylindrical body 30 of a cylindrical bearing part, and a viscous fluid 32 is sealed in between this shaft and the cylindrical body, so as to form a fluid bearing part 50 in this cylindrical body. A fluid sealing means 60 is provided on the upper end of the fluid bearing part. The sealing means is composed of only mechanical elements such as a groove 62 formed in a circumferential surface of the shaft or in an inner wall of the cylindrical body and a V-shaped projecting part 64 for generating air pressure formed at an upper end of the groove. Since a magnetic fluid is not used, no leakage of such a magnetic fluid itself takes place. Since an annular magnet for attracting this magnetic fluid is not required, a space for this magnet is saved, and hence miniaturization and thin formation are realized.

Title: Display unit for character or the like
Inventor: NAKAMURA HARUKA
IPC: G06F3/14
Filed: 1978-04-08
Abstract: PURPOSE: To enable a CPU to discriminate at a read time that data are inputted to a screen from a keyboard, by automatically adding a special code to the keyboard.  
     CONSTITUTION: Although a character code of nine bits including two specific bits is written into refresh memory M, the display control part ignores two higher bits and supplies the character code of only seven lower bits to character generator CG, where a corresponding character pattern is generated. Therefore, when a character code inputted from any one of alphanumeric key AK, ten-key TK and function key FK is the same code, the same character is displayed. At a read time, however, a character code of nine bits is all inputted to the CPU, where a character code of seven lower bits is read in at the same time as the discriminaton of the keyboard by two higher bits.

Title: Objective lens support of optical pickup
Inventor: USHITA TAKASHI
IPC: G11B7/09
Filed: 1984-03-06
Abstract: PURPOSE:To obtain a sufficient moving range by using a rectangular plate spring as a focus spring supporting an objective lens holder member freely movably in the optical axis direction. CONSTITUTION:The free end of the focus spring 24 made of the plate spring and the center of gravity of the holding member 21 being a moving part are placed nearly at the same position shown in point E. Thus, no bending moment is produced between the free end of the focus spring 24 and the holding member 21 being the miving part, and then no sub-resonanceof the focus spring 24 due to the bending moment is caused and a high gain servo operation is realized. Since the focus spring 24 is formed as a long rectangular form, the moving range of the objective lens 5 in the focus servo direction is increased.

Title: Production of double-ply pipes
Inventor: YOSHIDA TOSHIO
IPC: B21C37/06
Filed: 1981-03-24
Abstract: PURPOSE:To obtain self-tightening double-ply pipes which form a high rate of fitting at  working temp. by superposing an inside pipe of a coefft. of linear expansion larger  than that of an outside pipe relatively on the outside pipe, expanding these at the  temp. lower than the actual working temp., and allowing both pipes to make yield plastic deformation then reducing the pipes. CONSTITUTION:For the purpose of producing a corrosive fluid transport pipe for, for example, an atomic power device of high temp. TS, an outside pipe of a bore D0  and an inside pipe of an outside diameter Di(Di<D0) of carbon steel and stainless steel  respectively of alpha0, alphai(alphai>alpha0) coeffts. of expansion are produced in a factory of annual  average temp. TL. Next, the inside pipe is superposed relatively in the outside diameter, and when these are expanded by introducing and applying the water of the temp.  TL, the inside pipe abuts on the outside pipe and both pipes are integrally expanded  by causing yield plastic deformation. If the water pressure for expanding the pipes is  released at the prescribed diameter to reduce the pipes, the outside and inside pipes  reduce to D'0, D'i respectively. When the pipes made into a double-ply pipe state in this way are mounted to an atomic power device and are raised to the working temp.  TS, the diameter D'i is increased to D''i and the D'0 to D''0. Hence, the degree of fitting DELTAD of D'i-D'0 is formed automatically, and the inside and inside and outside  pipes are tightened to have tight contact with each other.
