IPC: F23C99/00
Filed: 1998-11-20
Abstract: PROBLEM TO BE SOLVED: To arbitrarily form a flat flame in a high temperature industrial furnace despite a simplified construction according to the size of the furnace. SOLUTION: The burner comprises a combustion nozzle 2N, and two oxidant nozzles 3aN and 3bN disposed up and down of the combustion nozzle. The nozzles are disposed slantingly with respect to the fuel nozzle 2N so that it collides with a fuel injected from the fuel nozzle 2N at a distance and at an intersection angle α from a vertical line, and an oxidant injected from injection holes 31a, 31b of at least each oxidant nozzle 3aN, 3bN can collide with a fuel from a vertical portion in a flat horizontal configuration. Even if there is any misorientation of the direction of the nozzle, a flat flame can be securely formed in the furnace with the aid of collision.

IPC: H04M1/64
Filed: 1990-11-29
Abstract: PURPOSE:To rapidly and surely reproduce data even if registered digital data is lost by providing a data read/write means which reads data stored in a backup storage means after a power cut is restored from when a feed state judgement means judges it to be the power cut and which writes it again in a storage means. CONSTITUTION:When the feed state judgement means 19 judges that power is fed from a power source to the storage means 15, the data read/write means 7 reads data which is previously stored in the storage means 15 and writes data in the backup storage means 25. Data written into the backup storage means 15 by the data read/write means 7 is stored in the backup storage means 25 until the power cut is judged to be restored from when the feed state judgement means 19 judges it to be the power cut. After the feed state judgement means 19 judges that the power cut is restored, the data read/write means 7 reads data stored in the backup storage means 25 and writes it again in the storage means 15. Thus, data can rapidly and surely be reproduced even if registered digital data is lost.

Title: Range division managing system
Inventor: KATABAMI NOBUE
IPC: G06F12/00
Filed: 1988-12-29
Abstract: PURPOSE:To shorten the processing time by determining an object range by a range defining means and a range determining means. CONSTITUTION:Relations between the range key value of a record and a corresponding range are defined by a range defining means 1, and a range determining means 2 determines the object range based on the range definition of the range defining means 1 at the time of requesting the access to a data base 5. A range referring means 3 requests reference of the record to the range determined by the range determining means 2, or a range updating means 4 requests storage, update, or deletion of the record to the range determined by the range determining means 2. Thus, it is unnecessary for a user to pay his attention to the range, and the processing time is shortened.

Filed: 1995-12-20
Abstract: PROBLEM TO BE SOLVED: To reduce the power of the level shifter circuit by reducing a short- circuit current of an inverter being a component of the level shifter circuit. SOLUTION: An input signal 109 whose level is within an absolute sum of a positive polarity electrode VDD and a negative polarity electrode VSS1 is given to a P-channel mOS transistor (TR) 101 and an N-channel MOS TR 102, from which an inverted signal 110 is obtained. The signal 110 is given to a capacitor 107, in and from which the signal is biased and outputted as a signal 111 to a gate of a P-channel MOS TR103. Simultaneously the signal 110 is given to a capacitor 108, in which its DC component is cut off and the resulting signal is given to an N-channel MOS TR 106, in which the signal is biased and outputted as a signal 112 to a gate of an N-channel MOS TR104.  The signal 111 (112) is inverted by a P-channel MOS TR103 (N-channel MOS TR104) and they result in an output signal 113 whose level is within an absolute sum of the positive polarity electrode VDD and a negative polarity electrode VSS2. Thus, the rising time and the falling time of the output signal 113 of the level shifter circuit are made equal to each other.
