Title: Surface hardening treatment for iron and steel by sputtering
Inventor: YOSHIDA KAZUHITO
IPC: C23C14/06
Filed: 1988-02-02
Abstract: PURPOSE:To form metal nitride as a surface hardened layer to a sufficient thickness by executing sputtering of the metals of groups IVa, Va, and VIa onto the surface of iron and steel and further subjecting the nitrides of the above metals to reactive sputtering. CONSTITUTION:Sputtering of one kind among the metals of groups IVa, Va, and VIa, such as Ti, is applied to the surface of iron and steel, by which a Ti layer is formed. Subsequently, N2 gas is supplied and the nitride of the above metal is subjected to reactive sputtering, by which metal nitride as a surface hardened layer, such as TiN layer, is formed. By the presence of the intermediate layer of Ti, etc., the adhesive strength of the metal nitride in the surface hardened layer can be improved. Further, the intermediate layer acts as a buffer between the iron and steel and the metal nitride at the time of thermal expansion.

IPC: B21B45/02
Filed: 1984-02-09
Abstract: PURPOSE:To obtain a product excellent in flatness by controlling the screening time of a sprayed coolant based on a sheet-shape value detected before cooling a high temperature steel sheet. CONSTITUTION:The sheet shape (the heights of an edge wave and a mid wave of sheet) of a high temperature steel sheet S rolled by a hot rolling mill 4, is detected by a sheet shape detector 5, to input the signals of detected results to a time-control arithmetic unit 6. The sheet width, sheet thickness, kind of steel, and temperatures at the times of starting and stopping colling, of steel sheet S, are previously given to the unit 6, which computes a proper time for screening both ends of the width direction of coolant screening-plates 3 by using said detected sheet-shape signals at the same time. The unit 6 performs the opening and closing control of plates 3 by controlling a driving means 7 of plates 3. Because the screening plates 3 are properly controlled by dividing the sheet shape into large and small edge waves, large and small mid waves, and a flat part, etc. the generating rate of mid wave is remarkably reduced, and a product excellent in flatness is obtained.

Title: Method and device for recording optical recording medium, and optical recording medium
Inventor: SASAGAWA TOMOYOSHI
IPC: G11B7/24018
Filed: 1997-02-06
Abstract: PROBLEM TO BE SOLVED: To reduce the fluctuation of recording signals and to suppress jitters to a lower level by conducting a recording compensation in accordance with the fluctuation of guide groove tracking signals while recording signals to the optical recording medium which selects a wobble system. SOLUTION: The compensation condition of the recording optical intensity, which corresponds to the fluctuation of the guide groove tracking signals, is determined by beforehand surveying the relationship between the recording optical intensity and data signal amplitudes and the relationship between the guiding groove tracking signals and the data signal amplitudes. By employing the determined compensation condition, the recording optical intensity is made stronger at the portion, where the deviation between the guide grooves and the position of an optical spot is large, and the data signals having no amplitude fluctuation are recorded.  When the compensation condition of the recording optical intensity corresponding to the fluctuation of the guiding groove tracking signals is not known beforehand, a recording test is conducted prior to the recording of user data or the compensation condition is recorded beforehand on an optical recording medium and the condition is determined by reading the condition.

At this point of time, the drainage in the vessel 3 is transferred to the aggregation vessel 9 through the branch pipe P 2  by shutting the valve 6 and opening the valve 8. Next, the drainage aggregated by flocculant, is sent to the precipitation vessel 11 through the valve 10 after its pH is regulated.

Abstract: PROBLEM TO BE SOLVED: To prevent noises from being generated in the reflected spectrum of a transferred optical waveguide diffraction grating by reducing zero-order light components, which is transmitted without being diffracted, as little as possible by forming the cross-sectional shape of the repeating pattern of recessed groove and projected line into almost sine wave. SOLUTION: A phase mask 1 is constituted by forming cyclic recessed grooves 3 into cross-sectional sine wave on one face of a quartz substrate 2. Concerning the grating having such a cross-sectional shape, theoretically, the transmissivity of zero-order light is 0% and diffracted light is concentrated to plus 1st-order and minus 1st-order. In order to form the recessed groove 3 into cross-sectional sine wave like this, the recessed groove 3 is temporarily formed into rectangular wave cross-sectional shape on the quartz substrate 2, afterwards, all the surface forming that recessed groove is etched and the edge of cross-sectional rectangular wave is smoothly removed. Concerning etching after the cross-sectional rectangular wave recessed groove is formed, dry etching is available but wet etching having higher isotropy is more desired.
