Abstract: PROBLEM TO BE SOLVED: To easily design gel time, improve consolidation durability and prevent pollution of groundwater and corrosion of an underground structure by using an aqueous solution of active silicic acid and an aqueous solution of acidic silica sol as effective components. SOLUTION: An aqueous solution of active silicic acid which substantially does not contain any salt is obtained by removing alkali ions from a water-soluble silicate such as sodium silicate and the like by means of an ion exchange method or the like and pH thereof is preferably less than 4. An acidic reactive agent is preferably added to the aqueous solution of active silicic acid to adjust pH at a value not more than 2 whereby the aqueous solution keeps stability for a long term and production not in site but in plant is enabled. The acidic reactive agent is preferably phosphoric acid. The amount of water glass to be added to the aqueous solution of active silicic acid in preparing a chemical liquid to be injected to soil is 25-300 wt.% of the amount of total SiO2 existing in the aqueous solution of active silicic acid.  Gel time can be arbitrarily and widely changed by changing a mixing ratio thereof.

Title: Method for automatically making bag out of continuous polyester film
Inventor: UCHIMOTO YOSHIAKI
IPC: B31B50/64
Filed: 1989-11-04
Abstract: PURPOSE:To rapidly obtain bag, which is favorably heat-fused, out of polyester film having greatly a heat deterioration property by a method wherein folded polyester film is continuously fed so as to mechanically repeat intermitted short-period processes such as pinching, cutting, gap expanding and heating processes. CONSTITUTION:When the tip edge of the film 6 running on pinchingly supporting tables 4 and 4a or a position corresponding to the width of a bag, pinchingly supporting plates 3 and 3a are lowered and a cutting edge 5 is instantaneously traversed to the film 6, which is held by said supporting tables 4 and 4a and supporting plates 3 and 3a under tension, in order to cut the film 6. By slightly shifting the film 6 on downstream side under the state being pinched by the supporting table 4a and the supporting plate 3a downstream, the gap between pinching parts is enlarged. In succession, a heating body 2 is lowered in the enlarged gap. Towards both the end edges of the cut film 6, the heating body 2 is brought close to the positions, at which the fusion of the respective end edges starts and further flowingly brought close to parts to be joined at the speed same as the contraction speed of the parts to be joined by fusion and finally seceded from the parts rapidly when the fully fused parts are formed in the parts.

Title: Paper feeder
Inventor: NAKAGAWA MASANOBU
IPC: B65H3/06
Filed: 1993-11-17
Abstract: PURPOSE:To prevent an erroneous paper feed such as double feed and empty feed, by easily obtaining a proper handling pressure. CONSTITUTION:A spring supporting shaft 15 is energized by a coil spring 16 to press a handling base 14, mounted with a handling plate 13, toward a paper feed roller 10. Between a paper feed plate 12 for supporting this spring supporting shaft 15 and a bracket 20, a cylindrical roll 17 is arranged to be fitted to the spring supporting shaft 15.

Title: Electrostatic charging brush
Inventor: KANARI KENJI
IPC: A46B15/00
Filed: 1994-11-24
Abstract: PURPOSE: To provide an electrostatic charging brush uniformly electrostatically charging the outer periphery of a photoreceptor. CONSTITUTION: As for the electrostatic charging brush 1 constituted by spirally winding and fixing a long substrate 3 where conductive fiber 2 having elasticity is flocked at the outer periphery of a shaft 4 whose cross-sectional shape is circular; the stiffness of the fiber 2 flocked on the outside is set to be weaker than that of the fiber 2 flocked at a center part in the width direction of the substrate 3, so that contact area for the photoreceptor is increased by making the bending quantity of the fiber 2 on the outside large, and therefore, the entire surface of the photoreceptor is uniformly electrostatically charged even in the case that the flocking density of the fiber 2 or the outside is low.  Also, a projecting part and a recessed part where the fiber 2 is flocked on both outsides in the width direction of the sufstrate 3 are alternately arrayed and formed, and the sufstrate 3 is spirally wound on the outer periphery of the shaft 4 so as to mutually engage the projecting part and the recessed part, so that the deterioration of the flocked density of the fiber 2 on both sides on the shaft 4 is prevented.

Title: Liquid/abrasive jet cutter
Inventor: YUUGEN ERU KURASUNOFU
IPC: B24C5/02
Filed: 1987-11-17
Abstract: PURPOSE: To avoid wear and tear of a nozzle by arranging a pump to supply liquid to the nozzle by pressurizing it as well as to supply its part to one chamber of a slurry tank, and arranging a means to control a supply quantity of high density slurry to the nozzle from the other chamber of this tank. CONSTITUTION: Water in a water tank 12 is pressurized by actuation of a water pump 14, and is supplied to a nozzle 22 through fluid pipelines 18 and 20. A part of this pressurized water is separated into one chamber 26a of a slurry tank 26 through a fluid pipeline 24 leading to the pipeline 18. This separating flow rate is controlled by a needle control valve 32, and a discharge quantity of high density slurry to the nozzle 22 from the other chamber 26b is controlled by moving a piston 28. As a result, the mixing ratio of the high density slurry to pure water in the nozzle 22 is adjusted, and a flow rate of pure water of the unit area in its outlet orifice is maintained costant.  Therefore, wear and tear of the nozzle are avoided, and it is injected into a workpiece (for example, glass and concrete) at a prescribed speed as a liquid/abrasive jet flow, and a high-quality cut line is formed.

Filed: 1995-11-07
Abstract: PROBLEM TO BE SOLVED: To provide an acceleration sensor capable of suppressing the propagation of the internal stress in a fitting base plate to an oscillating body when the external stress to be applied to the fitting base plate during the assembly or the atmospheric temperature is changed. SOLUTION: Projections 24a-24d are extended from supporting members 27a, 27b integrated with an oscillating body 23. The projections 24a-24d are inserted in a through hole 26 in a fitting base plate 35, the projections 24a-24c are adhered with the adhesive 30, while the projection 24d is adhered with the solder 28. Because the oscillating body is elastically supported by using the adhesive consisting of the elastic body, the propagation of the stress to the oscillating body from the fitting base plate is suppressed, and no distortion is generated in the oscillating body. As a result, the distortion of the oscillating body is not incorrectly detected as acceleration.

Title: Digital signal transmission system
Inventor: KONISHI MASAYA
IPC: H03M7/38
Filed: 1987-11-17
Abstract: PURPOSE:To reduce prediction error by generating a prediction signal from an envelope of a digital signal obtained through the selection of m-bit in a difference signal so as to prevent any overshoot from being caused in the prediction signal. CONSTITUTION:A difference signal dn is subjected to quantization where a minimum quantizing width is varied adaptively based on a control signal Cn by an adaptive quantizer 5 and further an m-bit is selected and sent as a digital signal pn. An envelope extraction circuit 7 outputs an envelope detection signal pne with respect to the digital signal pn and a prediction signal qn generated by a prediction signal generating circuit 8 is fed to a comparator 9, where the quantity with an m-bit reference signal from a reference signal generating circuit 10 is compared and a prescribed control signal Cn is generated and outputted. Since the envelope detection signal is not much steeply changed even if the output signal of the adaptive quantizer is changed steeply, the prediction signal is not changed steeply.
