Title: Method for evaluating dispersivity of dispersive liquid, method and apparatus for producing, and apparatus for applying the liquid
Inventor: TERAMOTO TAKAHIRO
IPC: G03G5/05
Filed: 1998-01-12
Abstract: PROBLEM TO BE SOLVED: To correctly evaluate dispersion stability of a high-concentration/high-viscosity dispersive liquid without changing a dilution state, etc., by impressing an a.c. voltage to the dispersive liquid with changing frequencies, and measuring electric characteristics. SOLUTION: Electric characteristics when an a.c. voltage is impressed to a dispersive liquid with frequencies changed are measured. Frequency dependence of the electric characteristics changes in accordance with a dispersion state of the dispersive liquid. Therefore, the dispersion state of the dispersive liquid can be correctly evaluated on the basis of the frequency dependence of the measured electric characteristics. For instance, the a.c. voltage is impressed to an application solution 2 to be measured via a pair of electrodes 4 facing each other via an insulating cell 3 storing the application solution 2. An impedance is measured by an impedance-measuring device 5. A predetermined operation process is added to the measured result at an operation device 7, whereby the dispersion state of the application solution 2 is measured. Dispersion stability can be evaluated with the same standard both at a laboratory level and at a production level.

Title: Method for pulling up single crystal
Inventor: TAGUCHI HIROAKI
IPC: C30B29/42
Filed: 1996-01-12
Abstract: PROBLEM TO BE SOLVED: To improve utilization efficiency of the semiconductor raw material by pulling up a single crystal with a CZ (Czochralski) method while continuously charging a semiconductor raw material so as to keep the amount of semiconductor melt constant and after stopping the raw material charge, further performing another single crystal pulling-up operation from the residual melt. SOLUTION: This method for pulling up a semiconductor, single crystal with a CZ method consists of: a first stage for performing a semiconductor single crystal pulling-up operation while continuously charging a raw material so as to keep the amount of semiconductor melt constant; and a second stage for further performing another single crystal pulling-up operation from the residual melt after stopping the raw material charge.  Since this method comprises not only the single crystal pulling-up operation with a CCZ (continuously charged CZ) method in which the amount of residual melt is large, but also the subsequent and final single crystal pulling-up operation with a conventional CZ method in which the amount of residual melt is small, by using this method, the amount of residual melt at the time of stopping the total single crystal pulling-up operations can be reduced and utilization efficiency of the semiconductor raw material can be improved to enhance the productivity.  Alternatively, after the above first stage, by performing a single crystal pulling-up operation with a CCZ method while gradually reducing the amount of raw material charge, the variation in impurity concn. due to segregation, etc., can be compensated to keep the impurity concn. constant and accordingly, quality of the semiconductor single crystal can be stabilized.

Title: Ultrasonic wave type wireless remote controller
Inventor: HAYASHI TOSHIICHI
IPC: G08C23/02
Filed: 1983-01-13
Abstract: PURPOSE:To extend the arriving range and to improve the directivity by performing reproduction with complete waveform width by a waveform shaping circuit of a monostable multivibrator circuit. CONSTITUTION:The secondary coil of a coil 11 constitutes a parallel resonance circuit with a capacitor 12 to select an object frequency component by utilizing the resonance. Its output appears at a point P, the potential at a point P is increased at the resonance and the potential at a point Q is also increased accordingly. On the other hand, components from a resistor 16 to an NPN transistor (TR)22 constitute a monostable multivibrator circuit and when the potential at the point Q is increased, its change is given to the base of the NPN TR19 to jump rapidly ON and turn off a TR22. When the discharge of the capacitor 18 is finished, the TRs 19, 20 jump respectively OFF and ON inversely and go to the original standby state. As a result, pulse waveforms 31, 32 inputted to a VIN are waveform-shaped by taking a voltage level 33 required to invert the monostable multivibrator circuit as a reference to output waveforms 34, 35.

Title: Elastic surface wave filter
Inventor: KINOSHITA YASUAKI
IPC: H03H9/25
Filed: 1980-01-21
Abstract: PURPOSE:To improve the ripple characteristics within the pass band by satisfying the relation of N=F/R<2>, where N is the electrode logarithm, F is the constant of the substrate and R<2> is the electro-mechanical coupling coefficient each. CONSTITUTION:The elastic surface wave radiated from sending-end transducer 1 reaches receiving-end transducer 2 to be changed into the electric signal. In this case, if the mismatching occurs, the re-excitation is given to the elastic surface wave at transducer 2 to cause the interference and then the ripple. If the perfect impedance matching is secured for either the receiving end or the seding end or for both of them, no ripple is caused. In this connection, the simultaneous matching is secured for both the phase angle and the absolute value of the impedance by deciding each value of electrode logarithm N, constant F of the substrate and electro- mechanical coupling coefficient R<2> to satisfy the relation of N=F/R<2>.
