Title: Semiconductor integrated circuit
Inventor: ONO YASUO
IPC: H01L27/14
Filed: 1985-03-28
Abstract: PURPOSE:To supply a compact optical clock signal, which is compact and is hardly lost, by forming an optical waveguide consisting of a transparent material having a refractive index higher than a material for an inter-layer insulating film into the inter-layer insulating film as a wiring for the clock signal. CONSTITUTION:An silicon oxide SiO2 is used normally as an inter-layer insulating film 7 in an silicon LSI, and the refractive index of SiO2 is 1.45. An optical waveguide 6 is shaped so as to be surrounded by SiO2, and wired to a striped shape by a transparent material having a refractive index higher than SiO2 such as an silicon nitride Si3N4 having a refractive index of 2.0 so as to be brought into contact with an N-type silicon layer 2. When the optical waveguide 6 side is used as the incident side, beams projected at an angle of incidence larger than a critical angle are propagated without being projected to the outside from the optical waveguide by total reflection. Since the optical waveguide 6 is not brought directly into contact with the silicon layer 2 in a photodiode section and silicon has a high refractive index as 3.6, total reflection is not generated in the optical waveguide, and the optical waveguide has transmittance of approximately 30%, thus efficiently projecting beams to the photodiode.

Title: Flow rate monitoring device
Inventor: KITA TOORU
IPC: G01F1/32
Filed: 1982-04-15
Abstract: PURPOSE:To detect visually a frequency signal by resonance of a vibrating piece by a vortex, by placing plural vibrating pieces whose resonance frequencies are different, in the flow direction of a fluid, in the downstream side of a vortex generating body. CONSTITUTION:When a fluid flows into a duct 18, a Karman's vortex 3 having a symmetrical shape is generated alternately toward the downstream from both sides of a vortex generating body 11, and this vortex flows to the downstream. The number of generation of the vortex 3 per time is proportional to a flow speed, therefore, a vibrator 12 is forcibly vibrated by vibration number being equal to emission frequency of a vortex from the vortex generating body 11, and among vibrating pieces 12A-12N of the vibrator 12, a vibrating piece having natural vibration number which coincides with this vibration number resonates by the maximum amplitude. Therefore, a measurer is able to know a flow rate value by reading a value of a scale 16 corresponding to a position of the vibrating piece which vibrates by the maximum amplitude among the vibrating pieces 12A-12N in this way.

Abstract: PURPOSE:To improve electrical characteristics by eliminating the orientation of ferromagnetic fine particles in the carrying direction of a nonmagnetic supporter when a flexible magnetic disk or a magnetic sheet is produced and attaining uniformly the disorder of orientation of the ferromagnetic particles. CONSTITUTION:A coating liquid obtained by dispersing ferromagnetic fine particles into a binder dissolved by a solvent is coated by a coating device 3 to a belt-shaped nonmagnetic supporter 2 consisting of polyethylene terephthalate, acetate, etc. which are fed out of a feed part 1. In this case, the ferromagnetic fine particle has the directivity along the coating direction owing to the fluid orientation. The orientation of the ferromagnetic fine particles in the coating liquid is disordered by a magnetic field generated from a nonorienting magnet 4 before the coating liquid coated on the supporter 2 is dried and hardened. Then the solvent in the coating liquid is deleted by a drying oven 5, and the binder is dried and hardened. Then the disordered ferromagnetic fine particles are fixed and held as they are.

Title: Energy recovering device in molten reducing iron manufacture
IPC: C21B13/00
Filed: 1992-03-18
Abstract: PURPOSE:To prevent nitrogen oxide or carbon dioxide from being discharged to the atmosphere by compressing exhaust gas including hydrogen and carbon oxide in an iron manufacturing furnace, driving an expansion turbine by combustion gas generated by combustion in an oxygen combustor, supplying steam and carbon dioxide to the oxygen combustor so as to decrease a temperature, and recovering heat and the carbon dioxide. CONSTITUTION:Exhaust gas including hydrogen gas, carbon oxide and carbon dioxide in a reducing furnace 1 is compressed in an exhaust gas compressor 4, to be thus introduced into an oxygen combustor 9. Although a temperature in the oxygen combustor 9 becomes 2000 deg.C or higher, the temperature is decreased by dilution with mixture gas of carbon dioxide, steam and the like, followed by combustion with oxygen, thus eliminating nitrogen. The combustion gas is expanded in an expansion turbine 10, to drive a generator 11. Moreover, heat of the gas is recovered or cooled, to reach a carbon dioxide recovering device 14. Consequently, heat can be recovered without dumping nitrogen oxide or carbon dioxide to the atmosphere.

IPC: G01N33/561
Filed: 1984-03-30
Abstract: PURPOSE:To inspect the state of a cell quickly at a high accuracy by measuring electrophoresis of the cell with an automatic type cell electrophoretic apparatus through an antigen-antibody reaction thereof to analyze changes in the pattern thereof. CONSTITUTION:An antibody is added to an isolated cell and after a fixed time of reaction, the electrophoretic value thereof is measured with an automatic type cell electrophoretic apparatus. Then, the electrophoretic value is converted into a histogram pattern to analyze. For example, peripheric blood of a normal person or an auto-immune hemolytic anemia patient is sampled and incubated with the addition of an antihuman IgG antibody thereto. Then, the blood is measured with the electrophoretic apparatus to analyze the pattern of the electrophoretic value. While the normal person shows no change in the electrophoretic value before and after the addition of the antibody but it can be recognized clearly that the patient changes to a low level in the pattern of the electrophoretic value after the addition of antibody as compared to that before the addition thereof. The pattern conversion of electrophoretic value facilitates the highly accurate measurement of cells.

Title: Ultrasonic probe for ophthalmology
Inventor: ARAGAI KAZUTERU
IPC: G01N29/24
Filed: 1989-03-15
Abstract: PURPOSE:To provide a low-cost ultrasonic probe for ophthalmology which has high sensitivity by a method wherein an irregular reflection film is laminated on the surface of a vibrator, and light from a light emission means is focused on the central part of a vibrator surface. CONSTITUTION:An irregular reflection film 42 is laminated on the surface of a vibrator 41 of an ultrasonic block 40, and light emitted from a light emitting means, e.g. LED 1 of an optical block 50 is focused to the central part of the vibrator surface by means of a focusing means, e.g. a lens 20. Then, focused light 15 is irregularly reflected by the irregular reflection film to form a light spot 12. Since movement of an eyeball is suppressed by fixing a patient's eye to the light spot, the light spot performs a role of an eye fixing point. Since there is no trouble even when the vibrator is present in the position of the light spot, there is no need to form a hole in the vibrator. This constitution prevents lowering of sensitivity of an ultrasonic probe for ophthalmology caused by a hole and prevents the increase of the number of manufacturing processes of the vibrator.
