IPC: C23C14/06
Filed: 1994-03-29
Abstract: PURPOSE:To obtain an alloyed Zn-Mg vapor deposition-coated steel sheet with Fe diffused to the surface of a plating layer and excellent in workability and corrosion resistance. CONSTITUTION:A continuously traveled steel strip with the surface cleaned is introduced into a vacuum chamber, in a reducing or inert atmosphere, deposited with Mg at >=100 deg.C and then with Zn. An alloying heat treatment is applied to the strip immediately after leaving the vacuum chamber at 330-600 deg.C for <=10sec in an inert atmosphere or in the atmosphere so that the Fe is diffused from the substrate steel to the plating layer surface. The Zn-plated strip is held at 200-400 deg.C for 1-25hr by using a heating furnace independent of the vacuum chamber to apply alloying heat treatment. Otherwise, the strip before Mg vapor deposition is kept at >=100 deg.C, the temp. is controlled so that the Zn-deposited strip is kept at 330-500 deg.C, and alloying heat treatment is conducted by the sensible heat of the strip.

IPC: G01R19/04
Filed: 1984-03-26
Abstract: PURPOSE:To reduce the influence of a noise and a dropout upon peak detection by detecting the amplitude of the rectified waveform of an input signal plural times and averaging detection results. CONSTITUTION:The input signal A is rectified by a rectifying means 10 into a half-waveform rectified waveform B, which is supplied to a detecting means 20.

Title: Instrument for measuring rise time of floppy disk driver magnetic head
Inventor: SANPEI FUMIO
IPC: G11B5/09
Filed: 1988-03-12
Abstract: PURPOSE:To inexpensively and correctly measure the rise time of a head reading signal by selecting and activating the magnetic head of a floppy disk driver (FDD) and comparing it with the output of a constant value holding circuit with a comparator circuit. CONSTITUTION:A floppy disk is inserted into a floppy disk driver (FDD) 1, and a prescribed magnetic head 2 is selected and activated. Next, the same head 2 is selected and activated again, and the output of a signal converting circuit 5 is changed. The output signal of the magnetic head gradually increases, and at such a time, it is compared with the output of a constant value holding circuit 3 by a comparator circuit 4. When both signals are at the same value, that is, when the reading signal of the head increases up to the constant value, the output of the comparator circuit 4 is generated. The output re-alters the output of the signal converting circuit 5. For this, when a signal changing time in the output of the signal converting circuit 5 is measured by a clock pulse counter, etc., a head activating rise time can be correctly measured.

Abstract: PURPOSE:To reduce the power consumption and to control the generation of waste water by using the steam after driving a gas suction fan in the desorption of an absorption tower, burning the obtained mixed vapor of steam and solvent (or after separated by condensation and cooling), and regenerating the desorbing steam by the produced heat. CONSTITUTION:The desorbing steam is utilized for a steam-driven fan 8 to drive a suction fan 1, and then used for the desorption ot absorption vessel 3. The obtained mixed vapor of steam and solvent is burned 12 as such, or the mixture is condensed, cooled 5, and separated 6 into waste water and the solvent which are burned 12. The steam used for the desorption is again generated by the combustion heat. By this method, the power consumption for the suction of gaseous solvent can be reduced, and the solvent which cannot be reused even when recovered is reutilized as the combustion improver for a combustion furnace. Meanwhile since the waste water is eliminated, the generated combustion heat is utilized in the generation of desorbing steam, and the amt. of boiler steam to be supplied from the outside of the system can be reduced.
