Title: Separation membrane for organic liquid mixture, device and method using the membrane
Inventor: IMAZU EMI
IPC: B01D71/34
Filed: 1997-10-22
Abstract: PROBLEM TO BE SOLVED: To obtain a separation membrane for an org. liquid mixture which is suitable for petroleum refining process and petrochemical industry by forming a nonporous layer on the surface of the membrane in contact with the org. liquid mixture to be separated. SOLUTION: The membrane distillation method is a membrane separation technique by which a component of a liquid mixture is selectively converted into an enriched vapor through a membrane having fine pores. The liquid mixture is supplied to the primary side of the membrane, while the secondary side of the membrane is evacuated or sucked with an inert gas or liquid such as nitrogen. In order to develop the separation performance of the separation membrane used, it is necessary that the component to be separated causes capillary condensation in the pores of the membrane. However, when the org. liquid mixture from the primary side intrudes into the pores of the film, the area to cause capillary condensation substantially decreases to decrease the separation performance. Therefore, a nonporous layer is formed on the surface of the membrane to be in contact with the org. liquid mixture.  Thereby, high separation performance and membrane permeation rate can be obtd. by the capillary condensation effect.

IPC: B60L11/18
Filed: 1992-10-23
Abstract: PURPOSE: To make it possible to reduce the number of semiconductor elements and the like, by reconstituting windings and the elements in at least an auxiliary operation mode in which the control semiconductors of a self-synchronous machine required for the fundamental or main operations of an electric motor and a generator correspond to a charger or a transformer. CONSTITUTION: In an electric motor mode, for instance, E1-E3 and E2-E4 of stator windings (HC) are offset 180 degrees. Choppers a, b, A, B shunt the stator current into HCE1+E2, E3+E2, E3+E4, E1+E4 or direct the current to form a revolving magnetic field. Diodes(DD) d1, d2 protect the choppers A, B. The current Iro of HCE5 controlled by the chopper C and protected by the DD d5 generates the magnetic field for a rotor. Also in a braking generator mode, the increase of the current Iro is represented by that of the electromotive force of the HCE1+E2, E2+E3, E3+E4, E4+E1. If the voltage exceeds the voltage of a battery Vp, a current Ist is allowed to pass, thereby charging the battery Vp.

Title: Surface potential reading device
Inventor: AONO TAKASHI
IPC: G01R29/12
Filed: 1993-12-10
Abstract: PURPOSE:To enable a surface potential reading device to scan a wide extent and to read the surface potential of a sample at spatial resolution of Prn order by bringing a probe nearer a recording medium and detecting the displacement of the probe by two-dimensionally scanning the recording medium or probe. CONSTITUTION:By forcibly vibrating a probe 1, the amplitude displacement of the probe 1 caused by the electrostatic force between the probe 1 and a sample 6 is detected. Namely, by irradiating the supported part of the probe 1 with strongly modulated laser light from a semiconductor laser 23, the irradiated part repeats thermal expansion and contraction so that the probe l can vibrate at the modulation frequency of the laser light. At the time of detecting the vibration of the probe l, a lock-in amplifier 24 detects the amplitude component of the same frequency as an exciting frequency. In addition, by providing a bias power source 11 between the probe l and sample 6, the bias voltage of the power source 11 is fed back and controlled so that the amplitude of the probe l can become constant. As a result, the value of the bias voltage varies in accordance with the potential at the sample 6 and the surface potential distribution image of the sample 6 is obtained by scanning the sample while the value of the bias voltage is recorded as a measured signal.
