Filed: 1990-07-26
Abstract: PURPOSE:To reduce the cost and to improve the reliability by controlling the speed of an electric vehicle produced based on the variation period of AC component in current fed from an inverter to a linear motor thereby eliminating a rotation detector. CONSTITUTION:When a linear motor 4 travels on a secondary conductor 41A having slits 43, air gap of the slit 43 increases thus causing increase of current I flowing through the linear motor 4. A current detector 11 detects the instantaneous value of the current I which is then converted through an effective value detector 12 into an effective value Ir and the AC component Ia thereof is then extracted by means of an AC component detector 13. A frequency meter 14 measures the period To of the AC component Ia and conversion into a speed (fr) of electric vehicle is carried out based on thus measured period To and the number of pole and pole pitch of the linear motor 4. An adder 9 creates the inverter frequency (fi) of the linear motor 4 which is then driven according to thus created inverter frequency (fi).

Title: Electrolysis method
Inventor: TSUGE HIDEO
IPC: C25B1/14
Filed: 1986-08-21
Abstract: PURPOSE:To continuously and stably carry out electrolytic operation for a long time by passing a DC pulse current or a DC rectangular pulse current at the specified time in electrolysis to prevent the deposition of inorg. matter on both electrodes when seawater, etc., are electrolyzed. CONSTITUTION:Seawater 12 is supplied from a supply pipe 9 into an electrolytic cell 10 by a pump P, and an electric current is passed between an anode 13 of a Pt sheet and a cathode 14 made of stainless steel to produce NaOCl. In this case, inorg. matter such as Mg(OH)2 is deposited on the cathode surface due to the Mg ion in seawater, and inorg. matter such as FeOOH is disposed on the anode surface. The electrical resistance between both electrodes 13 and 14 is increased because of the deposition of inorg. matter, hence the electrolytic reaction of seawater is inactivated, and the product NaOCl cannot be stably produced. In this case, a DC pulse current or a DC rectangular pulse current is passed between both electrodes for a time shorter than the transition duration for the deposition of the inorg. matter on the electrode surfaces to remove the deposited inorg. matter, and the production of NaOCl by the electrolysis of seawater is stably carried out for a long period.

Title: Manufacture of perpendicular magnetic recording medium
Inventor: HONDA KAZUYOSHI
IPC: G11B5/85
Filed: 1988-08-05
Abstract: PURPOSE:To enhance coercivity of the magnetic layer and to obtain high coercivity at low substrate temperature by irradiating the surface of the polymer substrate with an electron beam during the magnetic layer is formed. CONSTITUTION:While the long polymer substrate 2 wound off from a releasing roll 1 travels along the side of a cylindrical can 3, it is subjected to vapor deposition of a CoCr film or CoCrNi film from a vapor source 4 through the apperture of the mask 7 and then wound up by a roll 5. A bias roller 6 is used to make the substrate 2 adhere to the can 3. An electron beam 9 is emitted by an assisting electron gun 8 through the apperture of the mask 7 to irradiate the polymer substrate 2 during the film is formed. Either a direct-type or 270 deg. deflection-type gun can be used for the electron gun which scans the substrate surface in the longitudinal and transverse directions. Thereby, vertical corecivity can be increased, so that higher coercivity can be obtained than in conventional medium at a same substrate temperature. Namely, high coercivity at lower substrate temperature can be realized.
