Filed: 1994-09-14
Abstract: PURPOSE: To obtain a nubuck-tone artificial leather having soft handle and excellent surface characteristics such as coloring properties on the surface and buckling resistance without requiring extremely fining treatment at two stages. CONSTITUTION: A web is formed from conjugate fibers comprising two or more polymers and subjected to needle punching in the direction of thickness of the web to make an interlaced synthetic fibrous base. The interlaced synthetic fibrous base is impregnated with a first elastic polymer, compressed and squeezed. Immediately after the operation, before recovery of the compression, the interlaced synthetic fibrous base is impregnated with a second elastic polymer, compressed and squeezed and the first and the second elastic polymers are coagulated. Then the conjugate fibers constituting the interlaced fibrous base are extremely fined. The non-napped surface of the interlaced fibrous base is provided with a liquid containing a solvent for the second elastic polymer and the second elastic polymer is partially dissolved or swollen.  The liquid is removed, the interlaced fibrous base is solidified and the surface of the interlaced fibrous base treated with the solvent-containing liquid is treated with a paraffin.

Title: Pulse-type radar apparatus
Inventor: MURAMATSU TOSHIRO
IPC: G01S7/32
Filed: 1994-09-14
Abstract: PURPOSE: To obtain a pulse-type radar apparatus by which distance can be computed stably irrespective of whether the waveform of a reflected signal is large or small by measuring the time difference between a transmitting operation and the detection of a zero-crossing point. CONSTITUTION: A directional coupler 103 to which the high-frequency signal of a VCO 101 has been input sends the high-frequency signal to a switch 105, and it sends a part to a mixer 109. The ON-OFF of the switch 105 is controlled 106, and the ON- time corresponding to a pulse width is set as a length covering one frequency portion of an intermediate frequency. Consequently, a pulse-shaped high-frequency signal having the pulse width of the length is transmitted 104, a reflected signal at an object, to be detected, which has been received 107 is input to the mixer 108, a frequency difference from the high-frequency signal from the coupler 103 is output as an IF signal. An IF circuit 109 filters the signal, it outputs an IF signal waveform, and a signal processing part 110 finds the zero-crossing point of the waveform so as to specify the central position of the waveform.  Then, the time difference between the central position and the rise point of a transmitted wave is measured, and distance up to the object to be detected is computed. Since the time difference is constant irrespective of whether the waveform is large or small, the distance can be measured stably.

Title: Method of preparing solution for redox-flow battery
Inventor: KAMIO ZENJI
IPC: H01M8/18
Filed: 1983-11-25
Abstract: PURPOSE:To enable an active material solution which can be favorably used for a redox-flow battery to be easily prepared by dissolving a raw material containing chromium and iron, such as a chromium ore or chromite, in hydrochloric acid before removing mainly heavy metals contained in the solution by depositing them on the electrode of a cathodic chamber through electrodeposition or adsorption. CONSTITUTION:After a raw material containing chromium and iron is crushed and dissolved into hydrochloric acid, the residue is filtered off from the solution. When a chromium ore or a similar material which does not easily dissolve in hydrochloric acid is used as the raw material, it is preferable that nitric acid be added as necessary in addition to performing heating during the dissolution. The thus prepared hydrochloric acid solution of chromium and iron is then introduced into the cathodic chamber of an electrolyzer so as to remove mainly heavy metals contained in the solution by depositing them on the electrode of the cathodic chamber through electrodeposition or adsorption. Through performing this process, heavy metals and nitrate ions contained in the solution are removed, thereby enabling current efficiency to be greatly increased.

IPC: H01B13/00
Filed: 1988-09-05
Abstract: PURPOSE:To obtain a superconducting magnetic field generator easily by providing a ceramic superconducting material layer on the peripheral surface of a cylindrical base material, making a spiral boundary region in the peripheral direction, and making both line ends terminals. CONSTITUTION:An oxide layer with the base material composition shown by A2B1C3L7-delta, is gradually attached by evaporation being oriented, on the outside surface of a cylindrical base material of magnesia ceramics. In the composition, A is Ba, Sr, or Ca; B is Y or lanthanoide series; and C is Cu or Cu whose part is replaced with one or more out of Ti, V, Cr, Mn, Fe, Co, Ni, and Zn. Besides, 0<delta<0.5 is satisfied. Than, laser light is applied in the peripheral direction into a spiral shape to denature a superconducting material layer and to form a non-superconducting boundary region with a width of 100Angstrom  or so. By the use of this constitution, the irradiation of the laser light does not influence the orientation of the superconducting material layer, so a superconducting line can be formed keeping its high-grade orientated state. Besides, the process is repeated to thicken the superconducting material layer.
