Patent JP-S6459818-A (JP)
Title: Electrode for dry etching apparatus
Inventor: MATSUSHITA YASUO
IPC: H01L21/302
Filed: 1987-08-31
Abstract: PURPOSE:To obtain an electrode whose consumption in a plasma is little and where few foreign substances fall from the surface of the electrode by a method wherein a polycrystalline sintered substance of a nonoxide-based ceramic whose covalent bond performance is strong, whose purity is high, which is conductive and which can be sintered without adding an additive such as a sintering auxiliary agent or the like is used as an electrode material. CONSTITUTION:A B4C powder with a purity of 99.5% and with an average particle diameter of 100mum is filled in a graphite die whose diameter is 120mm; after that, it is sintered by a hot pressing operation via an upper graphite punch and a lower graphite punch. A condition for the hot pressing operation is as follows: a temperature is increased from room temperature to 2150 deg.C in about 2 hours; the temperature is held at 2150 deg.C for 0.5 hour; after that, a power supply 6 is turned off; the inside of a furnace is cooled. A load of 30MPa is exerted at 1900 deg.C, and a sintered substance is held at 2150 deg.C for 0.5 hour and is removed (an open porosity rate of the sintered substance is about 20% and its resistivity is about 8OMEGAcm). This sintered substance is machined to be an electrode shape and is used as a counter electrode 3. Because B4C is composed of light elements, the number of foreign substances adhering to the surface of an Si wafer is reduced to less than 1/20; because it is a substance of covalent bond performance and its melting point is high, it is hard to decompose; a life of an electrode can be approximately trebled.

Title: Control method of gas turbine having two-stage type burner
Inventor: ENDO TOMOYOSHI
IPC: F23R3/30
Filed: 1993-08-31
Abstract: PURPOSE:To permit the continuous operation of a gas turbine even when abnormal combustion is generated in a second stage combustion unit by a method wherein combustion is shifted to the independent combustion of a first stage combustion unit only when the conditional amount with respect to burning condition has exceeded an allowable amount. CONSTITUTION:When a difference between the maximum value 3 and the minimum value 4 of respective exhaust gas temperatures 1, detected by (n) pieces of thermocouples, has exceeded an allowable value, it is deemed that abnormal combustion has occured and a signal 7 is transmitted. When one of (n) pieces of thermocouples is disconnected and a difference between a second value 8 from the minimum value of exhaust gas temperatures and the maximum value 3 has exceeded an allowable value, it is deemed that abnormal combustion has occured and a signal 11 is transmitted. Further, when either one of respective widths of fluctuations in the exhaust gas temperature 1 has exceeded an allowable width of fluctuation, it is deemed that abnormal combustion has occured and a signal 14 is transmitted. In this case, the command of shifting to the independent operation of a first stage combustion unit is transmitted by the transmission of either one of the signal 7, the signal 11 and the signal 14.

Title: Method and apparatus for direct and continuous casting of thin metallic product
Inventor: FUIRITSUPU BURAN
IPC: B22D11/06
Filed: 1990-08-15
Abstract: PURPOSE: To easily execute trimming work at the edge part of a product and work dividing the product in the longitudinal direction by forming a line having weak mechanical resistance almost in parallel with the edge part of the metallic product on the surface of the metallic product at the time of solidifying molten metal. CONSTITUTION: A different structural portion is intentionally formed in parallel with the edge part near the edge part of the product and the brittleness of the product at this portion is made large so as to easily develop a crack. This defective portion forms a breaking zone convinient at the time of removing burr at the edge part. Therefore, the burr removal can be executed with a more rudimentary designed machine than such type of edge part burr removal machines as to be used for the outlet side of the strip rolling mill. The separation can easily be executed from a residual portion of the product by only folding the edge part.

Inventor: TOMITA TOSHITERU
IPC: H01J9/34
Filed: 1982-12-07
Abstract: PURPOSE:To improve a finished form of welding while simplifying the constitution for preventing a lead wire from entering the insides of the lamp base pins by mounting a lead wire led-out from the bulb end part so as to project from the tip part and fusing the specific distant part from the tip parts of the lamp base pins. CONSTITUTION:A stem 2 is sealed tightly at both ends of a bulb 1 and a column wire 3 is planted on the stem 2 while an electrode 4 is fixed at the tip thereof. Further, a lead wire 5 is led out from said stem 2. On the other hand, as to a lamp base 6, the insulating plates 8 and 9 are arranged in-and-outside of a metallic lamp base shell 7 and its recessed part 7a while the lamp base pins 10 are planted on the insulating plates so as to hold them between. The tip part 10a of the lamp base pin 10 has the smaller diameter as compared with the root part and on said top part, a hole 11 having the bigger diameter than that of a lead wire 5 is formed. Thereby, the finished form of welding has little diversity thus reducing a rate of generated inferior forms.

Title: Frequency synthesizer
Inventor: MIYAKE YUKIHIKO
IPC: H03L7/18
Filed: 1985-09-27
Abstract: PURPOSE:To obtain an output signal with less side band noise by adding a phase error equivalent to the dead band to one of signals inputted to a phase/ frequency detector in advance so as to eliminate the dead band of a phase locked loop. CONSTITUTION:Two phase/frequency detectors 3-1, 3-2 are used, a delay is given to the output of a frequency divider 2 and a delay circuit 7 is provided to the pre-stage of the 2nd phase/frequency detector 3-2. In setting the delay time td of the delay circuit 7 so as to be equal to a dead band 2DELTAphi2, a slight error signal appearing at the lock state of the loop is absorbed by the dead band of the loop and no substantial effect is given to the operation of the loop. Thus, the signal equivalent to the loop dead band is always added as a bias, then the loop dead band is eliminated.

Title: Protecting circuit for high frequency high voltage power source
Inventor: NOMURA NOBUO
IPC: H02H7/12
Filed: 1989-08-24
Abstract: PURPOSE:To protect a transistor and a high voltage transformer at the time of stopping an oscillation by rectifying a high frequency voltage of a primary side coil and cutting OFF a starting resistor from DC power source by a capacitor. CONSTITUTION:After a high frequency power source voltage is oscillated, a base current is fed to a transistor 3 to continue oscillation by a DC voltage Ve obtained by rectifying the high frequency voltage of a primary side coil 51 of a high voltage transformer 5. This voltage Ve becomes '0' when the oscillation is stopped. In this case, primary side impedance of the transformer 5 is reduced. However, since a starting resistor 2 is cut OFF from a DC power source by a DC cutoff capacitor 7, the base current does not flow to the transistor 3, and no collector current flows as well. Accordingly, an overcurrent does not flow to the transistor 3 and the primary side of the transformer 5 to be protected.
