Title: Method and apparatus for desalting
Inventor: TACHIBANA MINEO
IPC: C02F1/44
Filed: 1985-08-06
Abstract: PURPOSE:To dispense with the power of a booster pump, etc., by separating a pure water part and a raw liq. part with an osmotic membrane, separating a raw water part and a salt contg. liq. part with an ultrafilter membrane and compressing the raw liq. part with the osmotic pressure due to the passage of the water in a water supply part through the osmotic membrane. CONSTITUTION:The three zones, a pure water part A, a raw liq. part B and a salt- contg. liq. part C, are provided. When pure water 3 is supplied to the pure water part A, the water molecules in the pure water part A are permeated through an osmotic membrane 1 and transferred to the raw liq. part B. An osmotic pressure corresponding to the solute of the raw liq. part B and the ion concn. is exerted on the raw liq. part B by the transfer. The pressure is also exerted on an ultrafilter membrane 2 between the raw liq. part B and the salt-contg. liq. part C and the liq. is permeated from the raw liq. part B to the salt-contg. liq. part C. In this case, lower molecules of salts, etc., are permeated through the membrane 2, the permeation of comparatively higher molecules of proteins, etc., is blocked and the molecules are concentrated. Consequently, a raw liq. 7 is desalted and fractioned, the desalted liq. 9 is taken out from the raw liq. part B by a pump 10 and the salt-contg. liq. 10' is taken out from the salt-contg. liq. part C.

Title: Extra-high pressure hydraulic forming machine
Inventor: AMINO HIROYUKI
IPC: B21D26/031
Filed: 1988-07-15
Abstract: PURPOSE:To allow drawing, bulging, etc., under an extra-high pressure with good formability by joining an upper half frame and lower half frame which are respectively semicircular to constitute a spherical outer frame. CONSTITUTION:A blank W is installed to a die 90 of a lower frame 3. While a liquid is filled into a liquid pressure dome 9 through a liquid pressure port 91 from a confronted liquid pressure supply and control device A, the liquid is supplied into a blank holding cylinder 5 via a liquid pressure port 51 from a liquid pressure supply and control device B for blank holding. A mounting block 60 is lowered in a cavity 20 for guide in the upper frame 2 by the extension of a ram 40 when an inner cylinder 4 is actuated in the state of crimping the peripheral part of the blank W by said holder and a die 90. A punch 6, therefore, descends in the cavity 32 and comes into contact with the blank W, thereby pushing the blank into the dome 9. The generation of the counter liquid pressure is obviated and the pressure is increased in this way so that the blank W is wound around the punch 6. The counter liquid pressure acts directly on the blank W and since the pressure of the blank holding cylinder 5 can be regulated freely, the good drawing property is obtd. and the intricate forming is possible as well.

Abstract: PROBLEM TO BE SOLVED: To enable to easily control the density of dissolution and continuously run the apparatus by providing it with at least one powder feeder having an opening to put in specific amount of powder on the top and freely of turnable underneath and applying under it a dissolution basin to dissolve the powder. SOLUTION: When dissolving powder, a specified amount of previously measured powder then (powder for A-chemical dialysis undiluted solution) is put in several hopper(s) 1, then water in a dissolution basin 2 a little less than required amount is injected to be, agitated. The hopper 1 is turned on and it is stopped at a specified angle so that the powder inside falls into the dissolution basin 2. It is turned backward to its original position and it is again turned as far as it comes at a larger angle than before and stopped to eject the powder out. This action is repeated as much as required until all the powder falls off. The bottom face of the dissolution basin 2 is processed to a slant so that the injected powder is smoothly gathered onto the agitating space to be quickly dissoluted.

Filed: 1989-07-07
Abstract: PURPOSE:To eliminate the need for a special circuit by using an output voltage of a loop filter being a control voltage of a voltage controlled oscillator so as to control the tuning frequency of an antenna tuning circuit. CONSTITUTION:When a division frequency of a programmable divider of a PLL circuit 6 is set by a CPU 4, the PLL circuit 6 outputs a signal in response to a phase difference of a signal with a frequency divided by the programmable divider and of an output signal of a reference frequency oscillator 5 and a control voltage VF in response to the phase difference is outputted from a loop filter 7. The tuning frequency of an antenna tuning circuit 9 is varied by a change in the oscillating frequency of a voltage controlled oscillator 8. Thus, it is not required to provide a special circuit and the receiver is not made expensive.

Abstract: PURPOSE:To obtain a polyester excellent in electrostatic coatability, transparency, etc., by adding a Mg compound, an alkali metal compound, and a P compound to bis(beta-hydroxyethyl) terephthalate (oligomer), esterifying the mixture and polycondensing the product. CONSTITUTION:While terephthalic acid and ethylene glycol are being fed continuously or intermittently to bis(beta-hydroxyethyl) terephthalate (oligomer), the esterification reaction is started at 210-270 deg.C and a pressure of 1.0kg/cm<2> or below, and when the degree of esterification is within the range of 20-80%, 30-400ppm (in terms of Mg), based on polyester, of an Mg compound is added. During a period to the end of the precondensation reaction, an amount of at least one alkali metal compound selected from Mg compounds and K compounds which satisfies the relationship I is added, and during a period from the time when the degree of esterification reaches 91% to the end of the precondensation reaction, an amount of a P compound which satisfies the relationship II is added, and the mixture is esterified and then polycondensed.

Title: Temperature controller
Inventor: KATAYAMA HISAYASU
IPC: G05B9/02
Filed: 1985-08-12
Abstract: PURPOSE:To attain the use of a temperature sensor having a low impedance by providing a disconnection detecting circuit via a temperature sensor to produce a difference between the current flowing to an AC current source from a DC power supply circuit and the current flowing in the direction opposite to said first current. CONSTITUTION:A diode 34 is connected in parallel to a resistor 30. When a temperature detecting electrode line 8 has a disconnection, a current I flows in a route, i.e., a DC power supply VCC of a DC power circuit 1   a capacitor 29   the resistor 30  the line 8   a temperature sensitive element 9   a heating element 5   a DC power supply VAC in the negative half cycle between sides A and E of the power supply VAC. While a current II flows to the power supply VCC from the power supply VAC in the positive half cycle between sides A and E of the power supply VAC. Here I<II is satisfied since the current II scarcely flow through the resistor 30 and flows through the diode 34. Thus the voltage of a high level is produced at a junction B between the capacitor 29 and the diode 34. Then a transistor (Tr) 16 is turned off and therefore the current of a constant current source 23 flows to the base of a Tr 28. Thus the detection signal VS of a disconnection detecting circuit 15 is always kept at L0 and the disconnection of the line 8 is detected.

Filed: 1988-07-14
Abstract: PURPOSE:To detect a target even when a PRF is small by selecting a Doppler filter, which is optimum for the target detection, from the size of the PRF and bus device speed information and executing control. CONSTITUTION:A flight data device 11 presents the speed of an airplane and the information of the PRF to be used in a radar device to a target detecting area deciding device 12. From the information to be obtained from the flight data device 11, the target detecting area deciding device 12 judges which range Doppler filter is controlled and outputs instruction to a Doppler filter controller 13. On the other hand, a Doppler frequency corresponding to the maximum speed of the target detection is obtained from an equation (4). Then, the Doppler filter controller 13 sends only the filter output of a necessary band, out of the outputs of a Doppler filter 7, to a video integrator 8 according to the instruction from the target detecting area deciding device 12. Thus, even when the PRF is small, a clutter can be prevented from being mistaken for the target.
