Title: Parallel multiplying circuit
Inventor: KATSUNO AKIRA
IPC: G06F7/508
Filed: 1988-03-25
Abstract: PURPOSE:To increase the multiplication speed by adding a function, by which the cell of a partial product is by-passed in case '0' exists in the multiplier bit to the cell and by-passing the cell to connect to the cell of the next stage in case multiplier bit is '0'. CONSTITUTION:A unit circuit 11 of a parallel multiplying circuit consists of a two-input AND 1, a one-bit full adder 2, pMOSs 12, 13, and 16, and nMOSs 14 and 15. Since the by-pass function consisting of two pMOSs 12 and 13 and two nMOSs 14 and 15 is added to the unit circuit 11 consisting of the one-bit full adder 2 and the two-input AND 1, this circuit 11 is operated in the same manner as the cell in a conventional method in case of bk=1, but the full-adder 2 is by-passed because of Si=Si-1, Ci'=Ci in case of bk=0. Thus, the delay due to passage in the full adder 2 is reduced to increase the multiplication speed.

Title: Optical demultiplex element
Inventor: NISHIWAKI YOSHIKAZU
IPC: G03H1/04
Filed: 1982-04-30
Abstract: PURPOSE:To vary the wavelength of the light which should be divided, by forming an optical waveguide on a substrate with a material which can vary reversibly its refractive index and then writing a diffraction grating by a double luminous flux interference method or an optical beam scanning method. CONSTITUTION:An otical waveguide 2 using single crystals of BSO and BGO is formed on a substrate 1. Transparent electrodes 3 and 3 are formed by vapor deposition on both end surfaces of the substrate 1 and the waveguide 2 respectively. Then the DC voltage is impressed to the electrodes 3 and 3 from a power supply 4 via a switch 5. Both BSO and BGO show an electro-optical effect only when a DC field exists and produces the photosensitivity. The diameter is enlarged for two lumnous fluxes given from a laser, and these luminous fluxes are irradiated to the waveguide 2 of an electro-optical material with equal incident angle phi. An interference is given to the two luminous fluxes when an electric field exists to generate a change of refractive index in response to the interference fringes. The change of the refracive index corresponds to the interference fringes. When the space between gratings is set as (d), only lambda1 is diffracted for mlambda1=2nd cosQ (Q: incident angle of waveguide light 8 and m: number of order).

Abstract: PURPOSE:To obtain the semiconductor laser device having the predetermined characteristics with good reproducibility by arranging a groove-deformation preventing layer consisting of GaAlAs in adjacency of the surface of the GaAs substrate provided with an U-groove of striped form to restrain deformation of the groove. CONSTITUTION:A groove-deformation preventing layer 26 of 0.1mun consisting of Ga0.6Al0.4As and a GaAs layer 28 of 0.1mun thick are successively formed on an N type GaAs substrate 24 followed by usual photoresist process and etching process to form a groove 30, for example, whose width (v) is 4+ or -0.2mun and depth is 1mun. GaAlAs in which molar concentration of AlAs is 0.1 or over is hardly deformed at liquid phase epitaxial growth, but, the surface is apt to be oxidized so that if the surface is exposed to the air once, good epitaxial growth can not be obtained. Then, the GaAs layer 28 is added to the groove-deformation preventing layer 26 successively to enable the good epitaxial growth. when the thickness of the groove-deformation preventing layer 26 becomes over 0.2mun, the exposed area of the surface of GaAlAs of the side walls of the groove to be exposed and oxidized becomes too large to achieve the good epitaxial growth.

Abstract: PURPOSE: To eliminate sense of incompatibility from an operator, who is measuring information about an eye under examination, by memorizing an image of a fore eye part and displaying it as an still image in a displayer, when the information about the eye under examination is measured with reflected light from the eye under examination. CONSTITUTION: When power supply is switched on to a control switch 308, drivers 316 and 317 operate through an arithmetic and control circuit 301 to turn simultaneously all light sources 40, 41, 42 and 30 on, while a drive circuit 313 operates through the arithmetic and control circuit 301 to scan an image receiving element 5. Then, the arithmetic and control circuit 301 is changed over in order that an analogue signal from the image receiving element 5 may be conveyed through a gate circuit 302 to a display interface 304. Thus, a fore eye part of an eye under examination is illuminated by light from the light source 40, while alignment light from the for-alignment light source 41 is reflected on the fore eye part.  The light from both sources passes through a measurement optical system from a cornea measuring system, and forms respective images as an image of the fore eye part on the image receiving element 5 and as an image of the light source 41 which is an alignment index.
