Filed: 1996-09-09
Abstract: PROBLEM TO BE SOLVED: To execute the discharge of a high-mol.-wt. component only when the sepn. efficiency of a low-mol.-wt. component is good by regulating the starting condition of a substitution liquid pump by the differential pressure between the separating membranes of a plasma component separator and limiting the upper limit of a substitution liquid pump flow rate in accordance with the flow rate of a plasma pump. SOLUTION: The starting of the substitution liquid pump is in principle regulated by the differential pressure TMP2 between the separating membranes of the plasma component separator and 1 the substitution liquid pump flow rate is regulated by a substitution liquid flow rate setter and receives the limitation by the flow rate of the plasma pump. The substitution liquid pump is so set as to stop when the TMP2 is below a substitution start set pressure Pα and to start running when the TMP2 rises above Pα. The value of Pα is set at the min. differential pressure under which the sepn. of the high-mol.-wt. component and low-mol.-wt. component of the separating members is considered to already attain the required state. When the TMP2 exceeds a limit value, the clogging of the separating membranes is judged to be progressed.  The plasma component sepn. is then stopped and the back washing of the separating membranes is started.

Title: Heat-insulating sheet made of paper
Inventor: OSADA HIROYASU
IPC: B65D5/56
Filed: 1995-08-23
Abstract: PROBLEM TO BE SOLVED: To obtain a heat-insulating sheet made of paper wherein paper recycling may not be obstructed and aluminum may not remain as dust after incineration by forming a smooth reflection face due to transfer of an extremely thin layer of aluminum vapor deposition on at least one of paper members among a liner and a core of corrugated fiberboard. SOLUTION: An extremely thin layer 4 of aluminum vapor deposition is transferred on an cuter face of a surface liner 2 for double-faced corrugated fiberboard having liners 2, 3 on both faces of a core 1, and a heat-insulating sheet S having a mirror-like reflection face 5 is formed. The extremely thin layer 4 of transferred aluminum vapor deposition is formed by vacuum-deposit aluminum particles on a transfer plastic film, and adhesive is applied on an aluminum deposited face to transfer onto a paper face. Although a face 6 adhered to the paper is relatively rough in this case, an outer face which has been deposited to the film is formed as the extremely smooth reflection face 5.  Thus significant heat insulation due to reflection of radiation heat can be obtained, while recycling and incineration of the paper may not be obstructed since the aluminum layer is an extremely thin layer with a very small quantity.

Title: Estimation of life in high temperature water for ni-based alloy and iron fe-based alloy
Inventor: ITO HITOMI
IPC: G01N17/00
Filed: 1991-09-18
Abstract: PURPOSE:To estimate the life of the Ni-based alloy and Fe-based alloy in the high temperature water by obtaining the ratio of the total sum of the length of particle field carbide for the total sum of the particle field length in each of the Ni-based alloy and Fe-based alloy. CONSTITUTION:600 alloy based on a Ni-base in which the precipitation state of particle field carbide is changed is previously prepared, and the stress corrosion crack time in the pure water having a temperature of 360 deg.C is obtained. The 600 alloy is treated with the electrolytic etching having a 0.5A/cm<2> in a 10% aqueous solution of nitric acid, and after the distinct discrimination in the particle field is enabled, the 4500X electronmicroscope observation is carried out, and the total particle field length and the total particle field carbide length are obtained from the observation photographs by an image processor, and the total particle field carbide length/total particle field length = particle field carbide ratio is obtained. The obtained particle field carbide ratio and the stress corrosion crack time are plotted, and correlation is obtained. Since the obtained stress corrosion crack time is the estimation value in the vicinity of 320 deg.C, the temperature accelerating factor alpha is obtained by the comparison of the tests which are carried out at 360 deg.C by using the material having the high sensitivity, and the stress corrosion crack time at 360 deg.C is multiplied by alpha, and the stress corrosion crack time in the vicinity of 320 deg.C is estimated.

Title: Cmos operational amplifier
Inventor: SASAKI TSUNEKI
IPC: H03F3/45
Filed: 1997-09-03
Abstract: PROBLEM TO BE SOLVED: To improve circuit constitution efficiency and performance. SOLUTION: In the circuit constitution of an output stage 4, N-channel MOS transistors NM8 and MN9 and P-channel MOS transistors MP8 and MP9 are newly inserted compared to a former one. Then, MN8 connected to a node N1 (the connection point of the drain of a fourth P-channel MOS transistor MP4, the drain of a third N-channel MOS transistor NM3 and the gate of a fourth N-channel MOS transistor NM4) is constituted like a mirror circuit with a phase inverted input transistor NM4. The mirror ratio of MN4 and an output transistor MN7 can freely be set without changing the size of MN7 with such circuit. Since a current mirror circuit is newly inserted, an area can be reduced when the current circuit is inserted compared to a case when MN7 is enlarged. It is because a large transistor is originally used for the output transistor for preventing the break by static electricity and therefore the area of the amplifier becomes larger if the transistor is enlarged much more.
