Title: Sheet for liquid absorption and production thereof
Inventor: AOKI MASAHIRO
IPC: D06M101/16
Filed: 1988-08-18
Abstract: PURPOSE:To obtain the subject sheet having high initial liquid absorptivity, durable absorptivity of liquid) and excellent chemical resistance by discontinuously coagulating a polymeric substance in the gaps between fibers of a non-woven fabric consisting of three-dimensionally interlocked synthetic fibers in such a manner as to keep a specific void ratio. CONSTITUTION:A treatment liquid containing a soluble polymeric substance (e.g., PVA) and a dry-coagulable polymeric substance (e.g., synthetic rubber latex such as acrylic resin emulsion or nitrile-butadiene rubber) is impregnated in the gaps between the fibers of a non-woven fabric consisting of three- dimensionally interlocked ultrafine synthetic fiber having a fineness of 0.2-0.5de. After coagulating the coagulable polymer in dry state, the soluble polymer is dissolved and removed to obtain the objective liquid-absoribing sheet having a void ratio of 50-90% and containing the coagulated polymeric substance in discontinuously dispersed state. A liquid-absorbing sheet having excellent acid resistance or alkali resistance can be produced by using a polyester fiber or polyamide fiber as the synthetic fiber and a sheet for chemical treatment having excellent chemical resistance can be produced by using polypropylene fiber as the synthetic fiber.

IPC: E04G21/02
Filed: 1999-07-21
Abstract: PROBLEM TO BE SOLVED: To provide a concrete placing method and a concrete placing mechanism for easily and compactly placing concrete even on the independent column of high story. SOLUTION: Concrete is flowed into a form 4 through a flexible pipe 22 whose inside diameter is six inches, a tapered pipe 23 whose upper end inside diameter is six inches and lower end inside diameter is four inches and ready mixed-concrete discharge piping 24 from a concrete hopper 21. When concrete is passed through the tapered pipe 23, an aggregate is uniformly dispersed since falling energy is relieved and agitated again, and since concrete flowing velocity is more gentle than the conventional, concrete is compactly placed. Furthermore, a piping connection part is one part of a connection part between the tapered pipe 23 and the ready mixed-concrete discharge piping 24, and since air is difficult to be dragged in from the piping connection part at the time when it passes in the piping, concrete is further compactly placed.

Title: Liquid crystal display and method of liquid crystal display
Inventor: TSUCHIDA SUSUMU
IPC: G09F9/00
Filed: 1996-08-06
Abstract: PROBLEM TO BE SOLVED: To prevent liquid crystal from getting burnt when a vertical synchronous signal with a different period from a normal one is inputted. SOLUTION: A counter 74 starts counting synchronizing with the pulse of the vertical synchronizing signal inputted just before, and when a count value reaches 480 or more which is an effective horizontal number of lines of a display screen, an output to an AND circuit 70 is made to be a state of 'H'. Therefore, a periodic pulse of 480 or less is masked by with the AND circuit 70. A counter 75 counts the count value with reversed sign, which is counted by the counter 74 one frame in advance, as an initial value. Therefore, when a signal of a period corresponding to 480 or more of an effective number of lines is inputted, the same pulse as one frame front is generated by counter 75, and when the pulse of the vertical synchronizing signal to be inputted next is inputted at shorter period than usual, masking is done with a counter 76 and an OR circuit 78.

Title: Production of cordierite honeycomb structural body and molding auxiliary for molding the same
Inventor: KOIKE KAZUHIKO
IPC: C04B35/634
Filed: 1998-07-07
Abstract: PROBLEM TO BE SOLVED: To produce a cordierite honeycomb structural body in which the wall thickness of a cell is thin, without causing molding failure such as coming- out of the cell. SOLUTION: The maximum particle diameter of powder of a cordieritized raw material is regulated to <=85% of slit width of an extruder. Coming-out of a cell is prevented by preventing particles of the raw material from being clogged in the inside of a slit or in the inlet of the slit. Further, porosity of a honeycomb structural body is made larger than 30% by using talc having >=5 μm average particle diameter as one of cordieritized raw materials. The cordierite honeycomb structural body which is thin-wall and has low heat capacity, is produced with good moldability.

Abstract: PURPOSE:To realize the titled array of high reliability by arranging island-form photoconductive elements formed in an array in the main scanning direction on an insulation substrate and having a specific thickness in the part where the electrodes are formed, and by forming signal lead-out electrodes thereon. CONSTITUTION:After a photoconductive film is evaporated on the insulation substrate 1 by vacuum evaporation, island-form elements 2 in an array are formed in the main scanning direction by photoetching and heat-treated under the saturated vapor pressure of CdCl2.
