Title: Production of raw material for kaolinite-based synthetic clay
Inventor: OKADA TOKUICHI
IPC: C01B33/18
Filed: 1988-12-07
Abstract: PURPOSE:To industrially mass-produce the subject raw material for synthetic clay almost equivalent to natural clay by mixing a specified amt. of quick lime or slaked lime into various siliceous materials, subjecting the mixture to hydrothermal reaction and exposing the formed hydrated calcium silicate compd. in an oxidizing atmosphere to convert difficult-to-react quartz to easy-to- react silica. CONSTITUTION:The powdery quick lime or slaked lime is mixed into the various siliceous material powders having a high content of silica so that the molar ratio of CaO to (SiO2+Al2O3) is controlled to 0.2-2.0. An appropriate amt. of the easy-to-react A source (e.g. AlCl3) is then mixed into the mixture, water is further added in the acidic region at about pH 2, and the mixture is subjected to hydrothermal reaction at 150-250 deg.C for several hours. The formed hydrated calcium silicate compd. is exposed in an acidic atmosphere, and the difficult-to- react quartz is converted to easy-to-react silica. By this method, the raw material appropriate for efficiently producing the kaolinite-based synthetic clay almost equivalent to natural clay is produced.

IPC: G06F3/045
Filed: 1988-12-08
Abstract: PURPOSE:To prevent erroneous detection of contact position coordinates due to noise by increasing the time constant of an integrator in a variable oscillator and stopping counting for impedance measurement for a time longer than the time when the output voltage of the integrator is unstable. CONSTITUTION:A timing generator 35 generates a trigger pulse (b) synchonously with a switch element driving pulse (a), and this pulse (b) is inputted to a monostable multivibrator MM 44 to output a pulse (c) in the high level for a certain time Tw, and an oscillation pulse (d) from a variable oscillator 20 is inputted to a counter 46 through an AND circuit 45 for the time TW and is counted. Consequently, a terminal L1 of a touch panel 21 and a terminal R1 are connected to the input terminal and the output terminal of a voltage follower 43 respectively by the first pulse (a), and in this state, the counted value of pulses (d) obtained by the counter 46 is taken into a microcomputer by the rise of the pulse (b). Terminal L2 to Ln are successively connected to terminals of the voltage follower 43 in the same manner to obtain the counted value and an impedance calculated value based on the counted value. The counter 46 stops counting when the pulse (c) is in the low level.

Title: Computer graphic preference system having antialias
Inventor: GEIRII ESU WATOKINSU
IPC: G06T15/40
Filed: 1988-12-09
Abstract: PURPOSE: To generate a picture having high quality by determining a priority advantageous to one of polygons on two planes based on one or more of c1 , c2 , (c2 a1 -c1 a2 ), (c2 b1 -c1 b2 ), and (c2 d1 -c1 d2 ) between coefficients indicating two planes.

Abstract: PURPOSE:To prevent the increase of the braking distance during the running on a rough road by providing a judging means, a signal generation interval detecting means, and a changing means reducing the decreasing speed of the braking oil pressure in response to the output signal on a control means. CONSTITUTION:A judging means 33 compares the wheel speed Vw with the first reference wheel speed Vr1, if Vw<Vr1, an H-level signal S1 is outputted. The second reference wheel speed Vr2 is set, if Vw<Vr2, a signal S2 is outputted. When the generation interval of the signal S1 is smaller than the preset time T1, a signal generation interval detecting means 51 judges that a vehicle is running on a rough road and outputs a detected signal, and a changing means 52 reduces the decreasing speed of the braking oil pressure in response to the output signal. A delay circuit 49 outputs an H-level signal continued for the preset time T2 in response to the input of the detected signal from the detecting means 51. The signal S1 is forcefully kept at an L level until the time T2 elapses after the vehicle is judged to be running on a rough road.
