Title: Method and device for separating fluids
Inventor: YOSHIOKA TAKEO
IPC: B01D53/22
Filed: 1979-01-22
Abstract: PURPOSE: To separate the two fluids having different diameters of molecules by a simple operation and a compact device by permeating a second fluid mixed in a first fluid through a thin porous film by utilizing the difference in permeabilities of the both fluids against a thin porous film.  
     CONSTITUTION: A storage tank (not shown) storing Flon-113 (C 2 Cl 3 F 3 ) in which N 2  and O 2  are mixed is connected to a suction hole 1a, and a suction pump (not shown) is connected to a discharge port 1b. The suction pump is started, and the pressure at the hole 1a side is reduced less than the hole 1b side through a film 2. As a result, the vapor phase part (N 2  and O 2 ) of the fluid at the hole 1a side is passed through the film 2, and led out to the hole 1b side. In this case, since the molecule diameters of N 2  and O 2  are smaller than the molecule diameter of Flon- 113, N 2  and O 2  are passed through the film 2 in a short period of time. That is, by utilizing the difference in the permeabilities, N 2  and O 2  mixed in Flon-113 can be separated.

Title: Toner replenishing device
Inventor: TSUCHIYA TAKAHIRO
IPC: G03G15/08
Filed: 1998-01-19
Abstract: PROBLEM TO BE SOLVED: To gently reduce the toner replenishing rate from a normal state by constituting a scraping means of plural scraping members different in toner scraping ability. SOLUTION: The scraping member 321 is provided with a tip blade 321e at the tip of an arcuate blade 321b. In contrast the scraping member 322 is not provided with the tip blade at the tip of an arcuate blade 322b. By providing the member 321 with the tip blade 321e, the distance between the member 321 and the inner peripheral surface of a fixed cover is formed smaller than the distance between the member 322 and the inner peripheral surface of the fixed cover. Therefore, the member 321 scoops up the toner more than the member 322 until the toner residual amount in a toner container becomes small. Namely, the members 321 and 322 are constituted so that there are a difference in the scraping ability. By such constitution, when the toner residual amount in the toner container becomes small, a carrying amount or a carrying rate is not lowered suddenly but reduced gently.

Filed: 1980-01-25
Abstract: PURPOSE:To permit automatic setting of a proper blind zone by drawing the reception ultrasonic wave above a given level after the detection of a given attenuation of the residual vibration of an ultrasonic transmitter-receiver accompanying transmission. CONSTITUTION:Through a transmission-reception wave change-over circuit 14, the residual vibration accompanying the transmission from an ultrasonic transmitter- receiver 15 and the reflected wave are rectified and smoothed by a diode 28, a capacitor 29 and the like in a residual vibration termination detecting circuit 27 and the envelope output is processed in a comparator 33. When the residual vibration attenuates to below a given level, the output of the comparator 33 inverts to low level. Thereby, the Q output of a JK type FF38 is raised to high level, so that  a JK type FF39 is reset. Similarly to that after the residual vibration has been attenuated to below the given value the reception ultrasonic pulse is raised to high level above the given value, the Q output of the FF39 is raised to high level by the low level inverted input via the comparator circuit 33 and an inverter 41, so that the ultrasonic reception wave is detected. Accordingly, a proper blind zone is automatically set to prevent the generation of errors and the like in measurement due to misreception.

Title: Matching system for antenna of direction finder
Inventor: SHINODA EIJI
IPC: H04B3/46
Filed: 1989-01-18
Abstract: PURPOSE:To enable attainment of a matching circuit being stable in a wide band by a simple circuit construction wherein a resistor having a resistance value equivalent to the characteristic impedance of a cable is inserted into the central part of a conductor constructing a frame-type antenna. CONSTITUTION:Marks L1 and L2 denote inductances of frame-type antennas l1 and l2, and when the reactance ¦omegaL1 + omegaL2¦ thereof is smaller sufficiently than a resistance value R1, the impedance viewed from the secondary side of a transformer T1 is equal to the characteristic impedance of a cable and complete matching is obiained. Although the transformer T1 turns to require consideration when R1 ¦omegaL1+omegaL2 with an increase in a measured frequency, a standing-wave ratio satisfies about 2.5 even then. In the case when a more excellent matched state is requested, it is only needed to add a capacitor C1 for compensating the reactance.
