Title: Clock synchronization system
Inventor: EJIRI SATORU
IPC: H04J3/06
Filed: 1997-03-12
Abstract: PROBLEM TO BE SOLVED: To quicken the frequency pull-in time of clocks and to monitor frequency abnormality in real time by calculating a frequency fluctuation amount per short time and performing control by it when system clock reference information SCR arrives in unequal intervals. SOLUTION: The SCR 0 which arrives at in a first time is loaded to a counter 6 as an initial value and a CPU 11 performs calculation from the SCR (n) which arrives at in second and succeeding times. That is, the system clock counter value SCCn of the counter 6 is latched to an FF 7 and calculated at the separation timing of the SCR (n). By the calculation, the frequency fluctuation amount Δf to the SCR of the SCC per unit time is obtained. Then, the frequency phase control of a voltage controlled oscillator VCXO 5 is performed corresponding to the frequency fluctuation amount Δf. Also, when the arrival time difference of the SCR is smaller than a prescribed value, since a reception SCR error affects frequency fluctuation, the calculation is performed by the SCR received in the next time at the time.

Title: Method of correcting white spot fault of photomask
Inventor: MIYAUCHI TAKESHI
IPC: G03F1/74
Filed: 1979-05-11
Abstract: PURPOSE:To produce an effective shadow at a projected image by irradiating an ion beam to a white spot fault caused by partly lacking a pattern film formed on a glass substrate to rough the exposed surface of the substrate when correcting the white spot fault. CONSTITUTION:When a Cr film 2 is coated to become a pattern film on a glass substrate 1, the Cr sometimes lacks to produce a white spot fault 3 thereon. When this fault 3 occurs, it is corrected as below. That is, an ion beam 25 is selectively rirradiated to the exposed portion caused by the lack 3 of the substrate 1 to form a wavy rough surface 26 thereon so as to produce a shadow similar to the presence of the Cr film thereon. When the fault 3 is very small, the beam 25 is throttled as a spot to form a circular deep recess 27 thereon to scatter the irradiated light 27 to carry out the similar effect that the film 2 is presented thereon in the same manner.

Title: Coherent light communication system
Inventor: ONAKA HIROSHI
IPC: H04B10/293
Filed: 1987-03-12
Abstract: PURPOSE:To obtain a sufficient reception sensitivity while using a conventional semiconductor laser by detecting the fluctuation of an intermediate frequency signal so as to give feedback to a local oscillation light. CONSTITUTION:A signal light and local oscillation light synthesized by an optical coupler 15 are inputted to a photodetector 17 via an optical fiber 16. The photodetector 17 has a nonlinear characteristic and when the polarized plane of the signal light and the local oscillation light is nearly coincident, the intermediate frequency signal having a frequency being the difference of mutual frequency is superimposed onto the DC component and outputted in applying photoelectric conversion to the synthesized light. A frequency discriminator 19 sends a voltage signal proportional to the frequency of the input signal to a local oscillation frequency control circuit 20, which applies feedback control to the driving current of a semiconductor laser in response to the fluctuation of the intermediate frequency. Thus, the intermediate frequency signal is stabilized, thereby resulting in improving the reception sensitivity.

Abstract: PURPOSE:To reduce a leak current, make formation easy, and enable high speed response due to small capacitance, by arranging a first electrode right above a resonator via at least a clad layer and arranging a second electrode outside the end surface of one side of the resonator. CONSTITUTION:Layers 101-105 are subjected to a stripe-type mesa etching. A p-InP layer as a buried layer is grown and buried on the both sides and the upper part of a mesa.

Title: Production and purification of protein fused to binding protein
Inventor: CHIYADEI GUAN
IPC: C12N15/62
Filed: 1988-03-10
Abstract: Methods and products are provided for producing and/or purifying virtually any hybrid polypeptide molecule employing recombinant DNA techniques. More specifically, a DNA fragment coding for a protein molecule, e.g. a polypeptide or portion thereof, is fused to a DNA fragment coding for a binding protein such as the gene coding for the maltose binding protein. The fused DNA is inserted into a cloning vector and an appropriate host transformed. Upon expression, a hybrid polypeptide is produced which can be purified by contacting the hybrid polypeptide with a ligand or substrate to which the binding protein has specific affinity, e.g. by affinity chromatography. The hybrid polypeptide so purified may in certain instances be useful in its hybrid form, or it may be cleaved to obtain the protein molecule itself by, for example, linking the DNA fragments coding for the target and binding proteins with a DNA segment which codes for a peptide which is recognized and cut by a proteolytic enzyme. The present invention also relates to certain vectors useful in practing the above process as well as to a bioreactor and methods employing the bound hybrid polypeptide, e.g. where the bound target polypeptide is contacted and reacted with a sustance which interacts with the bound target polypeptide to produce a desired result.

Title: Clad material for spectacle frame
Inventor: NAKASUJI KAZUYUKI
IPC: G02C5/00
Filed: 1989-03-09
Abstract: PURPOSE:To provide the clad material for spectacle frames which does not impair lightness in weight and corrosion resistance and is excellent in high-temp. strength and workability by concentrically and alternately superposing and forming 3 layers of Ti and Ti-based alloys and forming the outermost layer of the Ti layer. CONSTITUTION:If the clad material is made into the three-layered structure, a core material 1 is formed of the Ti, an intermediate material 2 of the Ti-based alloy layer and an outer layer material 3 of the Ti. The core material 1, intermediate material 2 and outer layer material 3 are so formed concentrically that the sectional area ratio thereof is >= 0.6 the material 1, 0.2-0.7 the material 2 and 0.2-0.6 the material 3. If the sectional area ratio of the material 3 is below 0.2, there is the possibility that the Ti-based alloy layer 2 under the outer layer material is exposed when plane working or grooving is executed. If the ratio exceeds 0.6, the size as the spectacle frame is limited and, therefore, the sectional area of the high-temp. strength material in the lower layer degrades eventually and the degraded strength is resulted. If the sectional area ratio of the material 2 exceeds 0.7, the occupying area of the Ti layer in the material 1 is below 0.1 and working is difficult.

Abstract: PURPOSE:To improve precision by correcting the drift of the measured value of a body to be measured by using the measured value of a standard sample of a physically and chemically stable material having equivalent characteristics to X rays to the body to be measured. CONSTITUTION:When X rays 14 radiated from an X-ray tube 2 strike a plated steel plate 15 to be measured, fluorescent X rays 16 are inputted to a detector 3 to detect the intensity of the flourescent X rays which varies with plating thickness. Standard samples 17 and 18 of chemically stable materials having less variation in characteristics with temperature and less variation due to the X rays while having equivalent characteristics to the X rays to the plate steel plate 15 are arranged near the plated steel plate 15. At prescribed intervals of time, a heat moves along a guide rod 8 by a motor 11 and a screw rod 9 to take measurements of those standard samples. From the obtained data, the variation extents of the offset and gain of a measurement system are calculated to correct the measured value of the plating steel plate 15.
