Title: Allowable minimum pupil diameter contracting optical system for eyeball function measuring machine
Inventor: TAKEDA TSUNEHIRO
IPC: A61B3/103
Filed: 1989-06-12
Abstract: PURPOSE:To sufficiently reduce minimum pupil diameter by adding an optical system for making the enlarged image of an eye with preserving optical properties between a projecting system in an eyeball function measuring machine and the eye. CONSTITUTION:When a lends L3 (f3=f) and a lens L4 (f4=f/2) are disposed, a light emitted from a point B is collected to a point D, and the parallel light in the point B remains parallel also in the point D, so that an optical relay system nearly preserving optical properties can be constituted. In this optical relay system, the width of the parallel light in the point B is halved, and the magnification vertical to the optical axis of the image in the point B is halved. Contrary to this, when an eye is put on a point D, an image with the doubled size of the eye is formed on the point B by the optical relay system. When the eye is focused to a target T placed in a position moved from the focus position A of a lens L2 by (x), the target T is seen from the point B as situated in the position of f<2>/x. Then, when the lens L3 acts on this image, the target T is seen from the point D as situated in the position of (f/2)<2>/x. Only by quadrupling a measurement value obtained by adding such an optical relay system, the minimum pupil diameter is halved, and the values of refraction and regulation can be easily measured.

Title: Manufacture of thin plate semiconductor device
Inventor: KOMATSUBARA TADASHI
IPC: H01L21/208
Filed: 1979-11-21
Abstract: PURPOSE:To obtain the thin plate of GaAlAs by etching a substrate crystal after a liquid-phase epitaxial layer has been formed on the crystal face (111)A of GaAs. CONSTITUTION:If the substrate crystal face which is contacted with the melted crystal is made to be (111)A, i.e., a Ga face of (111), the thickness is larger than that of a (100) face, and the thin plate whose light emitting wavelength is 9,000Angstrom  or less can be obtained. The P type inversion temperature of said epitaxial layer is about 930 deg.C. Therefore, even though the maximum maintaining temperature of the melted crystal is, e.g., 980 deg.C, and the increase in the amount of the deposition of the crystal is intended, the undesired change of the composition in the vicinity of the P-N junction is not caused. The elimination of the GaAs substrate by the lapping and etching treatment after the formation of the epitaxial layer is easier than in the case of (100) face crystal substrate. In this constitution, the thin plate of the highly efficient GaAlAs infrared ray emitting element can be obtained.

Title: Video camera with electronic zooming function
Inventor: TANITSU MASAHIKO
IPC: G03B5/00
Filed: 1993-06-22
Abstract: PURPOSE:To provide a compact and light-weight video camera device by using a double focal distance lens in place of a zoom lens to change the focal distance by means of only the movement of a single lens group. CONSTITUTION:A zooming operation instructed by a zooming instruction means 6 is divided into a focal distance changing operation of a double focal distance lens 1 and an electronic zooming operation by a zooming function dividing means 7. The focal distance changing operation of the lens 1 is performed by shifting a specific lens group on an optical axis by a fixed extent. Meanwhile the electronic zooming operation is attained when a desired electronic zooming magnification is decided by an electronic zooming magnification calculating means 8 and a desired electronic zooming function is obtained by a video variable power calculating circuit 4. As a result, the zooming ratios of 6-8 multiples are collectively attained by a lens system where the electronic zooming function is combined with a compact and light-weight zoom lens having rather small zooming ratios of 2-3 multiples.

Filed: 1979-11-22
Abstract: PURPOSE:To intend the smoothness of the surface of a substrate by piling up polysilicon on a semiconductor substrate together with irradiating a laser beam or the like. CONSTITUTION:When polysilicon is piled up from gaseous silane by opening against SiO2 on an Si substrate and irradiating a proper amount of laser, polysilicon is selectively formed only at the opening part and not formed on SiO2.  The crystal  structure of formed polysilicones is changed due to the laser irradiation, said crystal  structure being the same single crystal as the substrate or approximately a single  crystal. According to this structure the surface of the substrate is extremely smooth  and a detailed wiring on the surface hardly causes the breaking of wire.
