Title: Apparatus for preventing heater electrode meltdown in single crystal pulling apparatus
Inventor: SAITOH MASAO
IPC: H05B3/00
Filed: 1997-03-18
Granted: 2003-01-11
Abstract: The invention is directed to preventing meltdown of conductive metal electrodes 5, 5 used to supply current to a heater 104 of a crucible 103. A single crystal pulling apparatus comprises: the heater 104 which encircles the crucible 103, and the pair of electrodes 5, 5, respectively threaded to a pair of graphite intermediate electrodes 6 of the heater 104, and a voltage source 9 for supplying power to the pair of electrodes 5, 5. A switch 11 switches the power on and off. A watthour meter 10a, continuously measures the current flowing through the heater 104. Investigation by the present inventors showed that in the case of a crack 8 in a lower portion of the intermediate electrode 6, minute fluctuations occurred in the measured value of the current, arising from an electric discharge phenomena in the crack 8 prior to meltdown of the electrodes 5, 5. Therefore, if fluctuations in the electric current measured by the wattmeter 10a are outside of a tolerance range, the controller 12 switches off the switch 11, thus interrupting power to the electrodes 5, 5, and preventing meltdown of the electrodes 5, 5.

Title: Vector search method
Inventor: MAEDA YUJI
IPC: H03M7/30
Filed: 1998-03-26
Granted: 1999-10-01
Abstract: The present invention simplifies a codebook search in the vector quantization when coding an audio signal or the like, enhancing the vector search speed. Each of the M basic vectors in a noise code book 260 is multiplied by a factor ± 1 in a sign adder 270 and combined in an adder 280 to create 2M noise signed vectors. Here, the characteristic of the binary Gray code is utilized as follows. A change ΔGu obtained between a noise signed vector based on a signed word I of the binary Gray code and a noise signed vector based on a sign word u adjacent to the sign ward I and different from the sign word I only in a predetermined bit position v is used in such a manner that a sign word u' which is next to reverse the bit position v on the Gray code sequence can express a change ΔGu' from the noise signed vector by utilizing the fact that the sign word u' differs from the sign word u only in one bit position w excluding the bit position v. Thus, calculation is simplified, increasing the vector search speed.
