IPC: G06F13/42
Filed: 1995-03-14
Abstract: PURPOSE: To attain a high-speed data transfer by reducing the deterioration of performance owing to synchronization between the modules of different clock frequencies. CONSTITUTION: The synchronizing circuit 100 is provided with a synchronizing part 1 and a synchronizing method selection part 2. The synchronizing circuit 100 converts a data complete signal DCM outputted by synchronizing with the operation clock of a module M not shown in the figure from the module M into a data complete signal DCB synchronizing with the operation clock of a module B not shown in the figure. Next, the synchronizing part 1 generates the plural waiting request signals W0M to W3M of respectively different timings for switching data to be transferred from the module M to the module B and for suppressing the output of a data transfer completion signal corresponding to it. A selection circuit 17 selects one of these plural aiting request signals and sends it to the module B.  At the time of selecting an optimum synchronizing method corresponding to the difference between the clock frequencies of both modules, high-speed data transfer is attained.

IPC: B01D61/48
Filed: 1992-03-13
Abstract: PURPOSE:To keep the stable quality of water over a long period of time, to treat water of small volume to large volume and to facilitate maintenance and control by using a mosaic ion exchanger wherein cation exchange groups and anion exchange groups are alternately alleged produced by utilizing radiation graft polymerization. CONSTITUTION:A mosaic ion exchanger wherein cation exchange groups 17 and anion exchange groups 18 are alternately arranged produced by utilizing radiation graft polymerization is used in the desalting chamber of an electrodialytic cell to remove ions from a liquid. As ionizing radiation used in radiation graft polymerization, gamma-rays, electron beam or the like are pref. As the org. polymer used in the radiation graft polymerization, polyolefins are suitable. As an irradiation method of a base material with radiation, a pre-irradiation method bringing the preliminarily irradiated base material into contact with a monomer is advantageous. By this constitution, it becomes unnecessary to separately fill the desalting chamber with both cation and anion exchangers and the electrodialytic cell can be simply produced and easily made large-scaled.

Title: Method for measuring spectral characteristic of color filter and production of color filter
Inventor: KAWASHIMA HIKARI
IPC: G01M11/00
Filed: 1989-03-08
Abstract: PURPOSE:To measure spectral characteristics with high accuracy by forming color filters on apertures or light shielding parts and measuring the spectral transmittance of the apertures with spot light including the apertures and the light shielding parts. CONSTITUTION:A thin film 1 for light shielding, such as vapor deposited Cr film, is formed on a transparent substrate 5 and in succession, a photoresist is laminated thereon and after the photoresist is patterned by using a photomechanical process, the thin film 1 for light shielding is etched to form the patterns of the apertures 2. Color filter patterns 4 are in succession formed on the apertures 2 or the light shielding parts. The light shielding patterns where the filter patterns are not formed are then measured by the photometric spot 3 as a reference, following which the light shielding patterns formed with the desired color filter patterns are measured similarly. The value obtd. by subtracting the reference difference therefrom is the spectral characteristics of the desired filter patterns. The obtained spectral characteristics include the deterioration in characteristics in the edge parts, etc. The spectral characteristics of the microcolor filter patterns are thus measured with the high accuracy.
