Title: Production of fiber softening agent and fiber softening composition
Inventor: TOKINA NOBUO
IPC: D06M101/00
Filed: 1993-12-28
Abstract: PURPOSE:To obtain an inorganic fiber softening agent exhibiting unique softening effect by treating a solution containing acid clay with an alkali to adjust the solution to a specific pH and separating a dispersion exhibiting specific physical properties. CONSTITUTION:pH of an aqueous dispersion of acid clay is adjusted to >=6 in the state of 1% aqueous dispersion by adding an alkaline agent and stirring the mixture. The pH-adjusted dispersion is subjected to centrifugal separation and the supernatant is recovered to obtain a separated clay liquid having an average particle diameter of 10-5,000nm measured by dynamic lightscattering, an epsilon-potential of 30-200mV measured by electrophoretic light scattering and a purity of >=95% determined by powder X-ray diffraction. This softening composition imparts a fiber with soft and dry feeling without causing the discoloration of the fiber. As necessary, the dispersion is subjected to ion-exchange treatment with a polyvalent metal ion (e.g. alkaline earth metal ion) to form an ion- exchanged clay wherein about 40%-equivalent of the ionexchangeable cation is exchanged with the polyvalent metal ion and the separated supernatant is used as the softening agent exhibiting excellent softening effect.

Filed: 1988-12-29
Abstract: PURPOSE:To form silica films of desired thickness on the inner surfaces of pores of a catalyst carrier very simply and securely by heating a honeycomb porous silicon carbide sintered material at the given temperature in the oxidation atmosphere. CONSTITUTION:A base material 1 constituting a catalyst carrier is a porous silicon carbide material having high melting point of approximately 3000 deg.C and is formed in the honeycomb shape.

Title: Interpolation signal generator
Inventor: SATO KOICHI
IPC: H04N9/07
Filed: 1998-11-25
Abstract: PROBLEM TO BE SOLVED: To enhance resolution of an image that is generated by an interpolation signal produced resulting from applying interpolation processing to a pixel signal outputted from an image pickup element. SOLUTION: In the case that a color component of a pixel signal obtained from a processed pixel S is a red(R) component and an interpolation signal for the B component in the processed pixel S is calculated, a ratio of a value of the pixel signal of the processed pixel S to an average value of surrounding pixels of the target pixel S from which the R component pixel signal is obtained is calculated for an interpolation coefficient. Then the interpolation signal for the B component is calculated by multiplying the interpolation coefficient by the average value of surrounding pixels around the target pixel from which the blue(B) component pixel signal is obtained.  Thus, the interpolation signal of the B component can be obtained by taking a tendency in the change from the surrounding pixels of the target pixel producing the R component pixel signal to the processed pixel S into account. Thus, reproducibility in a luminance change among the adjacent pixels can be enhanced.

Abstract: PURPOSE:To perform detection of resin pressure inside a mold without providing a sensor inside the mold, by a method wherein at the time of clamping of the mold with a mold clamping motor, a load current to be applied to a mold clamping motor is detected and the resin pressure inside the mold is detected indirectly. CONSTITUTION:After starting of injection, a detected value 30a of current by the use of a current detecting device 30 and a set value 20Aa of current by the use of a current setting device 30A are compared with each other by a comparator 21. When the detected value 30A of current becomes higher than the set value 20Aa of current, a signal 21a is sent to a controller 22 from the comparator 21. High torque turning instructions are applied to a mold clamping driver amplifier 19 from the controller 22 based on the signal 21a and a mold clamping motor 15 is actuated with high torque. Since a load current applied to the motor to apply the torque to the motor is detected by the current detecting device 30, the resin pressure inside the mold at a cavity part 3 can be detected indirectly inside the mold.

Title: Multimedia multiplex reception method and device therefor
Inventor: KAKO TAKASHI
IPC: H04M11/06
Filed: 1998-11-26
Abstract: PROBLEM TO BE SOLVED: To reproduce two types of a data signal and a sound signal from a transmitted signal which is multiplexed/transmitted through the use of a single analog line by delaying a data signal point before judgment by a prescribed time necessary for the judgment of the signal point and taking a difference with the judged data signal point. SOLUTION: In a reception part 32, a received signal from which an echo component is removed is demodulated in a demodulation equalizing part 60 by using a carrier signal. A soft judgment part 62 uses a redundant bit added in trellis encoding on a transmission side from output data of the demodulation equalizing part 60, corrects an error on a line and judges a correct data signal line. A delay part 70 delays a data signal point before judgment by time required for judging the data signal point of the soft judgment part 62. An adder 72 subtracts the precise data signal point judged in the soft judgment part 62 from the data signal point before judgement, which is delayed by the delay part 70, and takes out an analog base band signal which is overlapped with the data signal point and which is made to be random.

Title: Membrane separation device
Inventor: SAWADA SHIGEKI
IPC: B01D65/10
Filed: 1992-12-16
Abstract: PURPOSE:To detect a leakage of primary-side unfiltered liquid from a membrane separation device. CONSTITUTION:Untreated water is separated using a membrane by a main membrane separation device system, and the permeating water is made to enter a filtration membrane unit 4. If any damage occurs on the filtration membrane 3a of the system 3 and the primary-side unfiltered liquid leaks to the secondary side, a turbid matter contained in the leaking primary- side unfiltered liquid is captured by the filtration membrane unit 4, so that the turbid matter no longer flows out of a treated water takeout pipe. If the turbid matter is captured by the precision filtration membrane 4a of the filtration membrane unit 4, a loss in the water permeation pressure of the precision filtration membrane 4a increases. Therefore, the leakage of the untreated water can be detected by detecting this pressure loss using a detector. Consequently, if the primary-side untreated water leaks from the main membrane separation device system 3, the turbid matter is captured by the filtration member 3a on the downstream side, so that the turbid matter is prevented from leaking into an area outside the membrane separation device. In addition, the leakage of the turbid matter from the main membrane separation device system 3 can be detected by detecting a rise in the water permeation pressure loss of the precision filtration membrane on the downstream side. Thus, any damage on the membrane of the main membrane separation device system 3 can be detected.
