Title: Separation of 2,6-dimethylnaphthalene
Inventor: MAKI TAKAO
IPC: C07C15/24
Filed: 1986-11-28
Abstract: PURPOSE:To separate the titled compound from a stock oil containing a mixture of dimethylnaphthalene isomers, by using a solid adsorbent consisting of a Y-type zeolite having cation site ion-exchanged with Li and using p-xylene as a desorbing agent. CONSTITUTION:A stream of a stock oil containing 2,6-dimethylnaphthalene and at least one kind of other dimethylnaphthalene isomer and/or a hydrocarbon having a soliding point range of 220-270 deg.C and/or its derivative is made to contact with Y-type zeolite having lithium at the cation site and packed in a chromatographic column as a single bed (adsorbent).

Inventor: OZAKI YUKIO
IPC: H05B3/14
Filed: 1989-10-31
Abstract: PURPOSE:To prevent fusion-rupture of a platinum wire of a heat generator's terminal and damage of an electrode part by combining a zirconia-based heat generator's terminal and a specified extension terminal composing an electrode with a platinum paste or a silver paste and binding them with cement mortar for fireproof binding. CONSTITUTION:A zirconia-based heat generator terminal 1 and a terminal with a shape adequate for binding to an extension terminal 2 made of lanthanum chromite or molybdenum disilicide are formed and they are combined by application of a platinum paste or a silver paste 4 and the combined part is closely fixed with cement mortar 3 for fireproof binding. As a result, stable conductivity is obtained and the extension terminal 2 having superior temperature coefficient of resistance at low temperature to the zirconia-based heat generator terminal 1 is connected with a leas wire at a room temperature or a low temperature part far from the heat generator terminal 1. In this way, platinum wire in the heat generator terminal part is prevented from fusion-rupture and damage of an electrode part is avoided and thus durability of the heat generator is extended.

Title: High-frequency power supply
Inventor: KANEDA MINORU
IPC: B23K13/08
Filed: 1998-10-06
Abstract: PROBLEM TO BE SOLVED: To obtain a high frequency power supply in which a control circuit can be simplified by a method, wherein a reserve inverter is not required in the case of the failure of an inverter, an operation which ensures a prescribed output mismatch in the impendance of a matching transformer is eliminated, and operation can be continued even when failure occurs to the inverter which is to become a master. SOLUTION: In this high frequency power supply, high frequency currents are obtained with a plurality of high frequency inverters 21 to 2N from the DC output of a converter 1. Then, the outputs of the respective inverters are voltage-added by respective matching transformers 31 to 3N so as to be supplied to a load. Then, a control circuit 6 is controlled synchronously when a gate signal which controls current outputs of the respective inverters in batch is generated according to the output-current detection signal of the inverter 21, A current detection, which is used to control the current limiter of the control circuit, continues its operation in such a way that a current detection gain is lowered according to the drop in an output current due to the occurrence of failures for each inverter.  The input and output ends of the failure inverter is separated by having the primary side of a matching transformer short-circuited. Thereby, a failure treatment is simplified, and an operation can be continued even in the case of the failure of a master.

Filed: 1990-10-22
Abstract: PURPOSE:To detect malfunction even in a range out of a point by using an output waveform after comparison of a waveform to be determined with an expected pattern as a trigger signal of a latch circuit. CONSTITUTION:A level comparison circuit 50 compares an input waveform 4 to be determined with comparison levels 1,2 by comparators 6,6' and the waveforms are output as comparator output waveforms 7, 7'. Then in a timing comparison circuit 51, an expected pattern adjusted by an expected pattern sampling circuit 8 and the output waveforms 7, 7' are logically compared by a logic determined circuit 10. Then a logic determination signal is used as a trigger signal of a timing determining circuit 14 and when the logic determination circuit is 'fail', the signal becomes '0   1'. Thus a signal of a data line (always '1') is latched and a FAIL signal is output as '1' from a 'Q' output to a final determination signal 17. The signal is cleared per sampling timing pattern of the expected pattern.
