Title: Lens system permitting short-distance photographing
Inventor: HAMANISHI YOSHINORI
IPC: G02B9/62
Filed: 1980-01-31
Abstract: PURPOSE: To obtain image-formation characteristics over a wide range by providing the 1stW3rd lens groups in sequence from the object side and by moving the 1st and 2nd groups toward the object side relatively when the focus is changed from the infinite to a short distance.  
     CONSTITUTION: The 1st group G 1  of lenses providing condensation, the 2nd group G 2  of convergent lenses, the 3rd group G 3  of divergent lenses and a diaphragm in the 2nd group G 2  are provided in sequence from the object side. To change the focus from the infinite to a short distance, the 1st group G 1  and 2nd group G 2  move toward the 3rd group G 3  relatively while expanding the interval between both the groups. consequently, the movement extent of the lens for focusing is small even in short-distance and high-magnification photographing and althrough the aperture ratio is relatively large, excellent image-formation performance can be obtained over a wide range from the infinite to a short distance.

Title: Lattice interference type displacement detector
Inventor: NISHIOKI NOBUHISA
IPC: G01D5/38
Filed: 1988-01-21
Abstract: PURPOSE:To enhance the S/N free from variations in detection signal due to changes in the wavelength of a light source, by providing a half mirror for splitting the beam from the light source into two and a mirror for respectively allowing the divided beams to be symmetrically incident to the same diffraction point on a diffraction lattice. CONSTITUTION:The luminous flux from a light source 31 is divided into two by a half mirror 40 and the divided fluxes are respectively allowed to be symmetrically incident to the same diffraction point 10A on a diffraction lattice by mirrors 42A, 42B. Therefore, even when the wavelength of the light source is changed, angles phi of diffraction together become small symmetrically and, therefore, the direction and position of the beams incident to photodetectors 22A-22C are almost constant and stable interference can be generated and a detection signal is stable. Since the reflected beam from the surface of a scale 10 is not incident to the photodetectors 22A-22C, detection signal having a good S/N is obtained. Further, since the beams are diffracted at the same diffraction point 10A, the error due to the inclination of the surface of the diffraction lattice is not generated.

Abstract: PURPOSE:To prevent a surface layer from damaging, and to apparently and effectively form an uneven pattern on the surface of the layer by forming it of synthetic resin, covering the surface of the layer body imparted with high developing property with skin which is suitably reduced at its softening temperature as compared with that of the layer body, and forming the uneven pattern on the skin. CONSTITUTION:A synthetic resin sheet C is hung horizontally, and heated to be softened at approx. 185 deg.C. Thus sheet C is disposed directly under the sheet superposing face of the lower end of the pattern with the surface layer (a) upside, evacuated in vacuum to strongly bring the sheet C into contact with the pattern mold through a skin 2. The sheet C is released from the mold to obtain a molding C' having clear uneven pattern (b). In this case, a surface layer body 1 maintains the hardness of the layer (a) and incorporates with high developing property. Accordingly, the strength of the layer (a) can be maintained even at a position extended at the time of molding, and the softening temperature of the skin (a) covering the outer face of the body 1 is suitably reduced as compared with that of the body 1. Therefore, the layer of the skin 2 can be effectively transferred with a clear uneven part to the layer (a) in a soft state at the time of molding.
