Title: Visual field enlarging film and its production
Inventor: MIURA AKIHISA
IPC: G02F1/1335
Filed: 1995-01-18
Abstract: PURPOSE: To prevent decrease in transmittance for parallel beams and to enlarge the visual field by forming plural projections each having a flat top face at the same interval on a base body in such a manner that a part or whole of the slope from the surface of the base body to the top part of the projection make a specificed angle. CONSTITUTION: This visual field enlarging film 13 si produced by forming plural projections (UV-curing resin) 8 each having a flat top face at the same interval on a base body (polycarbonate resin) 7 in such a manner that a part or whole of the slope from the surface of the base body 7 to the part of the projection 8 make a specified angle θ. Further, the phase difference of double refraction in the film intra- plane direction is controlled to >=10nm. By alternately forming the enlarging part and the flat part on the base body 7 as described, light beams transmit to the front side without deflection in the flat part, while the enlarging part has an enlarging effect for the visual field. Thereby, the visual field is enlarged in the vertical direction of the screen of a liquid crystal display without darkening an image in the front view.  Further, gradation inversion caused when the screen is seen in an oblique direction is prevented and optical distortion is prevented. The display can be easily mounted on a liquid crystal display device.

Title: Method for measuring amount of oxygen in gas
Inventor: NAKAZAWA MITSUHIRO
IPC: G01N27/41
Filed: 1983-01-17
Abstract: PURPOSE:To prevent the decrease in the accuracy of measurement by applying preliminary current on an oxygen ion conductive plate for a very short time thereby moving and stirring the oxygen in a diffusion hole and suppressing the temp. fall without decreasing the restoring speed of an oxygen cell. CONSTITUTION:An oxygen cell S is heated with a heater 4a and preliminary current is applied via an electrode 2 on an oxygen ion conductive plate 1 for a very short time. The oxygen in an isolated chamber C is released slightly to the outside through the plate 1 and the gas in the outside is introduced into a pipe 5, by which the oxygen in the pipe 5 is moved and stirred and the flow thereof into the chamber C is accelerated. Detecting current is applied on the plate 1 and regular pumping is performed via the plate 1. The pumping time or limiting current is measured, thereby the concn. of oxygen in the gas G to be measured is measured. If the inside diameter of the pipe 5 is uniform, the restoring time is considerably reduced and the reduction in the measuring interval and the improvement in responsiveness are made possible.

IPC: H01L21/3205
Filed: 1988-01-14
Abstract: PURPOSE:To improve coverage and reduce shoulder by repeating the bias sputter method or the sputter deposition process and etching process for wiring with superconductive materials. CONSTITUTION:When forming wiring with superconductive materials of semiconductor device which is equipped with substrates 10 and 20, SiO2 film 11 and 21, Y-Ba-Cu-O family superconductor wiring 12 and 22, and contact holes 13 and 23 by using the sputter method, the bias sputter method is used wherein bias voltage is applied to the substrate 10 side and the sputter deposition and etching are performed simultaneously. At this time, since etching characteristics have angle dependency, the deposited film becomes flat. Also, when performing deposition of film by repeating the sputter deposition and etching, it is difficult for etching gas to enter the lower side of shoulder part 24 produced by the sputter deposition so that it is possible to select only the conditions for enabling etching to be made to an upper side 22a of the shoulder 24. It allows coverage to be improved, shoulder part to be relaxed, thus preventing breakdown in superconductive status from occurring.

Abstract: PURPOSE:To form margin parts at the leading ends of toner images by providing a reflecting plate and giving even radiation light to photoreceptor by as much as the width corresponding to the leading ends in place of exposing the leading ends of the original to the photoreceptor. CONSTITUTION:A stationary reflecting plate 23 is disposed below an original platen 13 in the position on the original scanning start side. The optical axis X of the scanning projection optical system first scans the bottom surface of the reflecting plate 23 before it scans the original O. Hence, this reflecting mirror 23 is started of scanning earlier than the original O to diffuse and reflect the incident light and projects white images to a photoreceptor 1' through a mirror 14, etc. The original images are then projected in continuation to the scanning terminal end Q of the reflecting plate 23. Hence, the fine width portions of the leading end parts O1, O2 of the original are not projected to the photoreceptor 1'. In this way, the leading ends of the original O are not exposed to the photoreceptor and in place the radiation light is applied by as much as the width corresponding thereto and therefore margin parts may be formed at the leading ends of the toner images.

Title: Data load control system
Inventor: SAKURAI TAKESHI
IPC: G06F3/00
Filed: 1983-01-19
Abstract: PURPOSE:To shorten the time required for loading to improve the operating ratio of a control part, by making it possible that plural control parts receive the same load data simultaneously. CONSTITUTION:When load requests are generated in control parts 41-4n, a load request signal 6 is outputted to a load part 5. The load part 5 transmits load data 7 of a block number Nk following a preceding transmitted block number Nk-1. Counters 11-1n are counted up when receiving data 7, and counter values are reported to discriminating circuits 21-2n. Circuits 21-2n discriminate whether counter values are equal to the number (m) of all blocks of load data or not. Data 7 is transferred to control parts 41-4n together with addresses, which are calculated on the basis of the number Nk in operating circuits 31-3n, and are developed to pertinent addresses. When the load part detects the load request signal 6 again, load data of the next block number Nk+1 is transmitted. Counter values becomes (m) by repeating this operation, and the signal 6 is not outputted from circuits 21-2n, thus terminating the load.

Filed: 1978-01-24
Abstract: PURPOSE: To constitute at low cost the contactless circuit easily keeping the order of priority, by constituting the titled circuit of the photocoupler, analog switch, inverter, OR circuit, resistor, and capacitor.  
     CONSTITUTION: The transistor 1, diode 2 and capacitor 5 consitute the power source for the photodiode of photocouplers 12 and 12'. For example, if the starting switch 3 is put ON, the photocoupler 12 is also put ON, and the potential on the emitter side of the phototransistor of resistor 9 rises high. This high potential puts OFF the analog switch 7' through the inverter 10. As a result, even if the starting switch 4 is put ON, no voltage appears across the resistor 9', so that the interlock becomes possible. By inserting capacitors 8 and 8' of dissimilar capacity, if the switches 3 and 4 are simultaneously put ON, the elevating speed of the potential of resistors 9 and 9' are so different that the interlock circuit provided with the order of priority can be constituted.

Abstract: PURPOSE:To decrease insertion loss by holding part of a fiber for fixing in a non-contact state so that the ratio of the occupying area of a core to the occupying area of a clad is made larger. CONSTITUTION:Part 11a of the fiber 11 for fixing is positioned above in a part A to be heated and softened, then the part A to be heated and softened of an optical fiber strand 10 is heated by an oxyhydrogen flame burner 12 and in this state, the fiber strand is drawn to a tapered shape in the axial direction shown by an arrow. The part A to be heated and softened is reduced in diameter to the tapered shape in the above-mentioned taper drawing operation. Since the inclusion of part 11a of the fiber 11 in a tapered welded part 13 is obviated, the occupying area of the core 13a at the end face 13B of the tapered welded part 13 increases. The tapered welded part where the fiber 11 is not united to the clad is thereby obtd. and the insertion loss is decreased.
