Title: Polypropylene flame-retarded fiber excellent in color fastness to light, and its production
Inventor: SHIMIZU YOSHISHIGE
IPC: D01F1/07
Filed: 1998-11-11
Abstract: PROBLEM TO BE SOLVED: To obtain a polyolefin fiber hardly causing a toxic gas by the pyrolysis of a flame retardant even at the melt spinning, hardly damaging the effect of a photostabilizer even if both of a halogen-based flame retardant and a photostabilizer are included, hardly being embrittled, and excellent in color fastness to light, and further to provide a production method thereof. SOLUTION: This polyolefin fiber is obtained by adding 1-5 wt.% halogen- based flame retardant, and 0.1-3 wt.% alkylated hindered amine-based photostabilizer, to a polypropylene resin having 40 g/10 min to 100 g/10 min melt flow rate value, and drawing the undrawn yarn obtained by carrying out the melt-spinning at <=210 deg.C spinning temperature in a draw ratio within the range adjusted so that the fiber strength after the drawing may be <=5.3 cN/dtex. The obtained polypropylene flame-retarded fiber requires three times or more of the flame-contacting number when the flame-proof test is carried out by 45 deg. coil method, and has >=50% strength retention after 1,000 hr irradiation with the light of a carbon arc weather meter.

Title: Apparatus for estimating bias error of sensor
Inventor: OKADA TAKAMITSU
IPC: G01S5/02
Filed: 1995-12-11
Abstract: PROBLEM TO BE SOLVED: To suppress the accumulation of rounding errors of a computer related to a geometrical positional relationship of a target and a sensor and estimate a bias error accurately by making judgments with the use of a judgment method obtained from analyses of an observation regular matrix. SOLUTION: A first (second) observation device 3 (4) observes data input from a first (second) sensor 1 (2) and an observation matrix generator 9 obtains an observation matrix of (k) targets by outputs for every time. When a regularity judgment device 10 judges that the observation matrix is utilizable from a proper value of a dummy value of an error variance matrix of the observation matrix, the observation matrix is output to a latter stage. If the observation matrix is judged not to be utilizable, the matrix is discarded. Arm estimated value evaluation device 11 calculates a co-variance matrix of bias error estimated values from an output of the observation matrix judged to be regular and observed noises, and an estimated value calculator 12 calculates a dummy bias error value from the observation matrix and an output of the estimated value evaluation device 11.  A bias error of the sensor is estimated from an accumulated operated result.

Title: Developing processing method for tab tape and tab tape developing processor therefor
Inventor: INABA NAOFUMI
IPC: H01L21/027
Filed: 1998-11-12
Abstract: PROBLEM TO BE SOLVED: To provide the developing processing method of a TAB tape and a developing processor for this method by which the concentration of K2CO3 in developer can be always maintained within a fixed range, an exposed photoresist part can be uniformly dissolved and eliminated, the dimensional accuracy of the width of a lead wire is excellent without variance, the constant- quality TAB tape can be manufactured, operation can be continuously executed, productivity is enhanced and a cost is also reduced. SOLUTION: The concentration of K2CO3 in the developer stored in a developer storage tank 102 is measured. Then, when the measured result is over the upper limit value of a previously set control value, one part of the developer in the tank 102 is discharged as much as previously decided quantity and the new developer whose concentration is previously adjusted to the prescribed concentration is added as much as the quantity previously decided according to the discharge quantity. Thus, the concentration of K2CO3 in the developer stored in the tank 102 is always maintained within the fixed range.

Title: Stitching machine for darning eyelet hole
Inventor: NISHIZAWA YOSHIFUMI
IPC: D05B3/08
Filed: 1995-11-15
Abstract: PROBLEM TO BE SOLVED: To provide a stitching machine for darning an eyelet hole capable of easily correcting the darning trace of a needle for an eyelet hole deformed by various stitching conditions such as the kind and expansion/shrinkage of cloth to be worked, and stitch balancing thread tension after checking the identity of an eyelet hole part and a foot part and finishing the darning stitch with presentable looks. SOLUTION: In a stitching machine for darning an eyelet hole, the darning trace of an inner needle and an outer needle in an eyelet hole part as a whole is corrected to the left or to the right. In this case, sets of correction data in an X direction are, for example, previously stored in memory 37b for correction data in the X direction so that a deformed seam generated by various stitching conditions such as the kind and expansion/shrinkage of cloth to be worked, and stitch balancing thread tension can be corrected. The seam data for the entire eyelet hole part can be corrected only by designating any one of the sets of correction data in the X direction through a control panel 23 based on the deformed seam by the darning trace of a needle.  Thus it is possible to perform the darn stitching of the eyelet hole part with presentable seam looks and in simple and efficient working manner.

Title: Driving method for liquid crystal display element
Inventor: KONDO JUNJI
IPC: G02F1/1368
Filed: 1989-12-12
Abstract: PURPOSE:To improve view angle characteristics by making color filters of the same color correspond to plural adjacent picture elements and applying signal voltages which differ in signal amplitude. CONSTITUTION:Two picture elements 21 and 22 which adjoin along a scanning line 15 are combined as picture elements of the same color opposite a color filter 12 of the same color. A signal line 16 connected to one picture element 21 and a signal line 16 connected to the other picture element 22 are different and supplied with mutually independent potential signals. Then both the picture elements 21 and 22 are applied with signal voltages which differ in signal amplitude through the signal lines 16. Therefore, the transmissivity-signal potential characteristic is obtained by averaging the characteristics of those picture elements 21 and 22 and the visible inversion of light and shade of a display image plane is hardly caused. Consequently, the view angle characteristics are improved.

Title: Analytical method for oxygen in aluminum nitride
Inventor: FURUKAWA YOICHIRO
IPC: G01N21/35
Filed: 1997-11-25
Abstract: PROBLEM TO BE SOLVED: To provide an analytical method in which an internal oxygen amount close to a true value is measured quickly, by a method wherein aluminum nitride is heated so as to raise its temperature up to a temperature at which nitrogen gas due to its decomposition is not generated, an external oxygen amount is measured, the aluminum nitride is heated so as to raise its temperature up to a temperature at which it is decomposed and the internal oxygen amount is measured. SOLUTION: At a first stage, only external oxygen is decomposed, and it is heated and decomposed at a temperature at which it is bonded to carbon for a graphite crucible so as to generate carbon dioxide. A heating condition under which only the external oxygen is decomposed is set at a highest temperature at which nitrogen gas is not generated due to the decomposition of aluminum nitride. At a second stage, under a moderate condition under which the external oxygen is measured, the extraction of internal oxygen is insufficient. It is preferable to set a high temperature at which the aluminum nitride can be decomposed completely, and 5500 to 5800 W is preferable.  In order to separate the extraction peak of carbon dioxide due to the internal oxygen, i.e., oxygen, from the extraction peak of the external oxygen which goes out first, a method in which electric power is applied instantaneously so as to be held for a definite time is preferable.
