Abstract: PURPOSE: To cost-effectively form an irreversible optical recording medium by applying the dispersion of polymer spheres having a specific diameter on a flat auxiliary substrate, depositing a conductive.layer by evaporation on this layer, separating this layer and using the layer as a stamper. CONSTITUTION: The dispersion of the polymer spheres having the diameter from 200 up to 500nm in a solvent is applied on the flat auxiliary substrate. The thickness of this layer is increased until metallic replicas may be separated from each other. A metallic layer generally consisting of silver is applied on this layer by high-vacuum vapor deposition or cathode sputtering so as to have 0.1 to 0.5mm thickness. The resulted negative duplicate is used as an inscribing mold for forming a substrate having a textured surface and is obtd. by injection molding, injection inscribing, pressing or casting. A special gold layer or semiconductor layer having optical absorptivity of 5 to 95% and 10 to 50nm thickness is finally mounted on thereon.

Title: Optical information recording disk
Inventor: KOYAMA EIJI
IPC: G11B7/24015
Filed: 1986-03-20
Abstract: PURPOSE:To enable removal of disk substrates from an optical information recording disk which is integrally assembled by joining respective constituting members by joining means which can be disassembled. CONSTITUTION:This disk is constituted by adhering two sheets of the disk substrates 1, 2 by a hot melt type adhesive agent 5 via an inner peripheral spacer 3 and outer peripheral spacer 4 formed into bodies separate from the substrates. Since the respective constituting members are adhered by the adhesive agent of the hot melt type, the adhesive agent softens when the adhered parts are heated to the melting temp. or above. The respective constituting members can then be disassembled. The optical information recording disk is, therefore, obtd. by forming protective layers 8 having excellent chemical stability and airtightness on the surfaces of the recording layers 7 of the disk substrates 1, 2 taken out by disassembling the optical information recording disk of an air sandwich type and adhering the protective layers 8 of two sheets of such disk substrates to each other by means of the adhesive agent 9. The semi-permanent preservation of the recorded information is thus made possible.

Abstract: PURPOSE:To make it possible to emit liquid droplets of each color ink, by providing a nozzle containing ink having absorbability to radiation flux with a specific wavelength while performing the spot irradiation of the radiation flux with the specific wavelength to each nozzle. CONSTITUTION:Mixed radiation flux guided through a waveguide 10 is allowed to be incident to a diffraction grating 14 without being totally reflected from a part where the refrax index thereof is made same to that of the waveguide 10, that is, a shutter opened part 12 by a drive circuit 13 wherein a shutter array 11 is controlled according to a printing order. The radiation flux is diffracted while the diffracted fluxes are respectively guided to different directions corresponding to the wavelengths thereof. That is, radiation fluxes G, B are converged onto a lower surface 15a being a focal point surface by a lengs array 15. As a result, because nozzles 17-19 containing inks R, Y, B are subjected to spot irradiation with different radiation fluxes, bubbles are generated in each nozzle to inject liquid droplets.

Title: Synchronizing signal extraction system and cn ratio measurement system
Inventor: HIJIKATA SEIJI
IPC: H04N5/08
Filed: 1991-03-04
Abstract: PURPOSE:To extract the synchronizing signal of a MUSE signal and to measure a CN ratio with a circuit which is easily composed of parts which can generally be obtained. CONSTITUTION:LPF 2 removes the high frequency signal component of a video signal, a sound signal and an independent data from the inputted MUSE signal and gives the signal of a comparatively low frequency component such as a dead signal and a clamping level signal to COM 3. COM 3 compares a voltage reference signal Eref with the signal given from LPF. The dead signal period of a first or second line, which is set in a high level, is detected and outputted. The output is outputted as the synchronizing signal shaped in a prescribed pulse width through a pulse width discriminator 4 and a signal pulse generation circuit 5. The synchronizing signal is delayed by a delay time generation circuit 6 so that it agrees with the clamping level period of a 563-th line, and a reference pulse generation circuit 7 sets the signal to be a gate signal for extracting the signal of the clamping level period.

Title: Registering/retrieving system for data having hierarchical structure
Inventor: MURAYAMA TAKAHIKO
IPC: G06F7/24
Filed: 1989-03-14
Abstract: PURPOSE:To prevent the selecting efficiency error caused by the priority setting characteristics by providing a control table exclusive for the registration/ selection of data and attaining the selection of data with the optimum efficiency. CONSTITUTION:When the data 13 is registered, a register inlet 11 is first decided in response to a group to which the produced data 13 belongs. Then the list elements corresponding to the data 13 are registered into a list set ahead of a selection inlet 12. At the registration of list elements, the elements are sorted and registered according to the priority of the data 13 so that the data 13 having the highest priority is set at the head of the list. Thus it is possible to assure the optimum selection efficiency that is always fixed regardless of the priority and the order set among groups.

Title: Waveguide type photodetector
IPC: H01L31/10
Filed: 1992-03-18
Abstract: PURPOSE:To provide a photodetector with which two straight-advancing polarized lights can be photo electricity converted independently. CONSTITUTION:The title photodetector is composed of guide layers 2-1 and 2-2, a quantum well absorbing layer 3, a bulk crystal absorbing layer 4, an upper clad layer 5, an electrode 6-1 for TE mode detection signal and an electrode 6-2 for TM mode detection signal which are formed on a semiconductor substrate 1, and an electrode isolation groove 8 formed between a substrate-side electrode 7 and an upper electrode on the back side of the substrate. As the absorption-end wavelength of the TE mode light is longer than that of the TE mode light, the light in the vicinity of the absorption end selectively absorbs the TE mode light only, the TE mode light is transmitted. The transmitted TE mode light is absorbed by the absorption layer 4 and converted into an electric signal. As a result, the beam splitter for isolation of polarized wave is unnecessitated, and the constitution of the optical system of polarization diversity for coherent light communication can be simplified remarkably.
