Abstract: PURPOSE:To regenerate adsorbent without removing the same and to improve the adsorptive performance in the stage of adsorption by running cooling water in the heat transfer tubes disposed in a device in the stage of adsorption and running hot fluid thereon and drying and regenerating the adsorbents by utilizing lead-out pipings in the stage of regenerating the adsorbents. CONSTITUTION:The intrusion of a working medium is prevented by a valve 4, and after the working medium in a dehumidifying and desalting device 15 is run to a condenser, a valve 12' is opened to run hot fluid in heat trasnfer tubes 11. The hot fluid is discharged through a valve 13' to the outside of the system. During this time, the inside of the device 15 is warmed by heat conduction and the working medium stagnating in the device 15 is recovered as steam with a condenser. Thereafter, a valve 4' is closed, and a valve 10 is opened to blow air 8 to an ejector section 9, from which the air is run to the outside of the device through a chimney. As a result the steam heated in the inside is induced to regenerate adsorbents 2. In the stage of adsorption, the cooling water introduced through a valve 13 is passed through the tubes 11 to cool the inside of the device 15, whereby the performance in adsorbing moisture and chlorines from the working medium of a turbine by the adsorbents 2 is improved.

Title: Signal discriminator for magnetic recorder
Inventor: SATO NAOKI
IPC: G11B20/10
Filed: 1989-06-29
Abstract: PURPOSE:To obtain a device with simple circuit configuration and easy to be integrated by providing a timer re-started up at every input of a signal at the position of magnetic inversion and outputs signals representing the presence and the absence of the magnetic inversion, respectively at a time interval of specific times the minimum magnetic inversion interval. CONSTITUTION:The reproducing signal of a magnetic head 1, after passing a magnetic inversion detector (DM) 2, is outputted as a signal setting a pulse Pi at the position of the magnetic inversion as a pulse C1i with the presence of the magnetic inversion via a timer 3 operated with operating time of 0.5 times the minimum magnetic inversion interval T. Simultaneously, the pulse Pi is inputted to a timer 4 which generates a pulse with a time of (N+0.5) times the interval T. The timer 4, when the next pulse at the position of the magnetic inversion being inputted within the time of 1.5 times the interval T, is re-started up without outputting the signal with the absence of the magnetic inversion. Therefore, a signal COi with the absence of the magnetic inversion can be obtained after the lapse of 1.5T after the pulse Pi is inputted. Thereby, the device with simple configuration and easy to be integrated can be obtained without requiring a synchronizing signal generation circuit using a PLL.

IPC: H01M4/38
Filed: 1996-06-26
Abstract: PROBLEM TO BE SOLVED: To enhance a high rate discharge characteristic and a cycle characteristic by applying acid treatment to a hydrogen storage alloy in a condition concurrently provided with a specific metal. SOLUTION: A metal of Be, Al, Zr, etc., and a compound thereof are ionized to be fused by pH0.5 to 3.0, to be natured precipitated by pH4 to 6. Accordingly, in a stage of pH0.5 to 4 of acid treatment liquid, the metal is fused, in a stage rising to pH4 to 6 of the treatment liquid, the metal reacts with an OH ion and O2 in the liquid, to the precipitated as oxide and hydroxide, the OH ion or the like increasing pH is consumed. As a result, rising of pH of the treatment liquid is suppressed, to long stay in pH6 to 4. On the other hand, since Ni or the like in an alloy component, with treatment liquid pH4 to 6, is precipitated to sink, when the pH is maintained long to 4 to 6, its precipitation amount is increased, more Ni or the like is sunk in an alloy surface.  By this sinking, ruggedness of the alloy surface is enlarged, by increasing a specific surface area, a high rate discharge characteristic and a cycle characteristic are more improved.
