Abstract: PURPOSE:To attain high separation coefficient and high filtration rate in the pervaporation separation of a liquid mixture of water and organic liquid having a specific concentration using a regenerated cellulose membrane, by pretreating the membrane with a liquid mixture of water and an organic liquid having a specific concentration and containing specific cation and anion. CONSTITUTION:In the pervaporation separation of a liquid mixture of water and an organic liquid containing >=85wt% organic liquid with a regenerated cellulose membrane, the membrane is pretreated, prior to the above separation process, by pervaporation method with a liquid mixture of water and organic liquid containing 40-80wt% organic liquid same to or different from the above organic liquid, and containing one or more cations selected from Mn<2+>, Fe<2+>, Co<2+>, Ni<2+> Cu<2+>, Zn<2+>, Ce<2+> and Mg<2+> and one or more anions selected from SO4<2->, H2PO4<->, CH3COO<-> and NO3<-> at concentrations not to cause the separation of the mixture into two phases, while keeping the concentration of the organic liquid in the mixture to the above level. The separation coefficient can be improved remarkably by the pretreatment and the above separation process can be carried out at high separation coefficient and high rate of permeation.

Filed: 1984-03-02
Abstract: PURPOSE:To increase additionally the chemical fastness of the multi-color pattern manufactured by electrodeposition by bonding chemically a high polymer and a dye and forming a securer coloring layer. CONSTITUTION:A reactive dye has an active group such as monochlorotriazinyl group, etc. and induces a chemical reaction with the OR group of cellulose fibers or the amino group of nylon, wool and silk, by which said fibers are dyed. For example, a polyester anion electrodeposition resin contg. trimellitic anhydride and trimethyl propane as essential component monomers as a high polymer is made water soluble by neutralizing a carboxylic group by alkali or amine. A red reactive dye having a monochlorotriazinyl group is added thereto and the resin is heated. When the resin is made acidic, the dyed resin is deposited. A water soluble melamine resin is mixed therewith and is diluted to prepare a red electrodepositing bath. Striped color filters 8 in order of red, blue and green are produced by patterning, electrodeposition of read electrodes, curing, electrodeposition of blue electrodes, curing, electrodeposition of green electrodes and curing.

Title: Air filter paper
Inventor: MATSUOKA HIROSHI
IPC: B01D39/16
Filed: 1993-03-02
Abstract: PURPOSE:To provide a novel density gradient type air filter paper having high dust capturing efficiency and long service life. CONSTITUTION:Fiber layers consisting of low-density layers and high-density layers are adhered by moisture curing type adhesives. The low-density layers are functioned as a prefilter and the closing of the gaps of the high-density layers is prevented, by which a sufficient filtration life is obtd. The dust past the low-density layers are captured by the high-density layers and the filter medium having high performance is obtd. Film formability is extremely little as compared with the conventional water-soluble or non-solvent type adhesives if the moisture curing type adhesives are used to integrate both layers having different functions and, therefore, the possibility of closing the inter-fiber gaps is drastically reduced.

Title: Nuclear reactor, reactor core and component thereof
Inventor: TAKIYAMA MASASHI
IPC: G21C1/20
Filed: 1993-03-02
Abstract: PURPOSE:To simplify the structure of reactor core and to enhance thermal efficiency. CONSTITUTION:A pipe 11 encapsulating moderator is carried on water flow 21 produced by a hydraulic pump 48 through a guide pipe 8 with a part surrounded by a cap 14 as a guide 35 and enters retractively into the reactor core. A fuel assembly 3 is placed in a fuel guide pipe 15 in order to ensure cooling flow rate. A void is defined between a fuel guide pipe 15 and a cap 14. Consequently, moderator cooling facility is not required for pressure tube reactor. Furthermore, since a pressure vessel structure is substituted for calandria tank structure characteristic to pressure tube reactor, economy is enhanced. Output control, compensation of the degree of burn-up, and interruption of operation of reactor can be realized by varying the position of moderator encapsulation pipe 11. Quantitative ratio of coolant to fuel can be varied using the void in the cap 14 and the void is utilized for control of reactor core.

Title: Guide of rolling mill
Inventor: ISHIMOTO MASAKI
IPC: B21B39/14
Filed: 1979-04-06
Abstract: PURPOSE:To guide the strip to the best position in order to prevent the drawing, by combining frames of different length so as to be freely rotatable, by swinging these frames with the cylinder so as to hit the stopper, and by changing the swing fulcrum. CONSTITUTION:When the cylinder 12 is moved between the states A, B of the frames, the first frame 8 generates a turning moment around the pin 9 as the fulcrum, and a load is given to the second stopper 11; at this moment, the frame 8 stops its movement. On the other hand, the roller 5 receives the reaction force of the strip 4, and tends to turn the second frame 6 around the cylinder 12 as the fulcrum, however, this motion is stopped by the stopper 11. Next, when the frame 6 is brought down frm the state B, the frame 8 is joined by the joining device 14 and is obstruted from going down, but the frame 6 goes down to hit the first stopper 10. Hereby, the frame 6 turns around the pin 9 as the fulcrum, and the roller 5 parts quickly from the work roll 2 and enters into the housing 1.

Abstract: PROBLEM TO BE SOLVED: To eliminate fluctuation in the carrying speed of recording medium by providing a plurality of thermal heads facing a platen on the outside of a belt and abutting against the platen, and an ink ribbon being carried along with a recording medium while being sandwiched between the head and the belt. SOLUTION: A plurality of platen rollers 32-35 are arranged on the inside of a belt 30 between a drive roller 60 and a driven roller 61 at a recording section R. The platen rollers 32-35 are disposed rotatably while facing the forward end of thermal heads 25-28 through the belt 30 and an ink ribbon (r). The platen rollers 32-35 can be moved through a mechanism 40 between a position where they abut against the thermal heads 25-28 and a position where they retract therefrom. According to the arrangement, a slight difference of circumferential speed between platen rollers causes no fluctuation in the carrying speed of a recording medium. Consequently, image quality of the recording medium can be protected against deteriorating due to image shift.

Filed: 1979-04-05
Abstract: PURPOSE:To realize flexible exchange control by simplifying, by enabling one service trunk to receive a dial tone and dial signal and to send out the dial signal and service signal tone on origination. CONSTITUTION:When subscriber EX of a private branch exchange is placed in an off-hook state, it is connected to a trunk equipped with service trunk SRT, from which a dial tone is sent out. Next, dialing sends dial number information to central controller CC, which analyzes it to discriminate subscriber EX for a connection to a called subscriber. When outgoing to the outside is discriminated, a connection to outgoing trunk OGT is made. Under the control of controller CC, trunk SRT sends the dial signal to the party side via trunk OGT and is connected to the party called side. When the party is busy, a busy tone is sent out from trunk SRT.
