Title: Combustion device
Inventor: KONDO YASUO
IPC: F23D14/18
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To prevent a pilot flame (a flame produced by primary combustion) formed at the downstream side of a catalytic combustion portion from being blown down or becoming unstable caused by supplied secondary air, in the case where the secondary air is supplied to the downstream side of the catalytic combustion portion. SOLUTION: A catalytic combustion portion 4 by itself forms a recessed portion 20 of substantially conical shape at the downstream side of the catalytic combustion portion 4. A deflection flow guide 9a is disposed at a secondary air diffusing port 9 to cause a swirling flow from the secondary air diffusing port 9 to and inside a combustion chamber 6 to further cause a reverse flow at the center of the combustion chamber 6. The reverse flow stabilizes a holding flame space in the recessed portion 20, thereby stabilizing a starting flame formed in the recessed portion 20. Accordingly, the starting flame in the recessed portion 20 is prevented from being blown off or becoming unstable caused by secondary air, despite the increase of the secondary air supplied to the downstream side of the catalytic combustion portion 4 or lowering of the temperature of the secondary air.

Title: Information recording method for magneto-optical recording medium
Inventor: IIDA HARUHISA
IPC: G11B11/10
Filed: 1994-10-12
Abstract: PURPOSE: To greatly narrow track pitch of a magneto-optical recording medium while maintaining errorless information reproduction by decreasing the signal crosstalk from adjacent track to nearly zero. CONSTITUTION: Since the magnetization of a first magnetic layer 13 is directed in one inside over the entire surface of a medium after passing the inside of an initializing magnetic field Hini, all the information is once erased from the first magnetic layer 13. Since the direction of the magnetization of the second magnetic layer 14 is, however, not affected at all by the initializing magnetic field, the information is held in the second magnetic layer 14. Since the magnetization of the second magnetic layer 14 is transferred to the first magnetic layer 13 when the medium 1 is heated by a preceding first laser beam 2 up to a prescribed temp., the second laser beam (reproducing beam) 3 in succession to the preceding beam 2 reads out the magnetization transferred onto the first magnetic layer 13, namely, the reproduction is executed.  At this time, the heating up to the prescribed temp. by the preceding beam 2 is not executed in the adjacent tracks and the information is not transferred to the first magnetic layer 13 and, therefore, the crosstalks from the adjacent tracks are entirely eliminated.

Abstract: PURPOSE:To increase the conversion accuracy by amplifying or attenuating after an analog input signal is A/D-converted, applying A/D conversion to the output further, storing once both the said conversion output and correcting the result of the normalized amplification attenuating rate. CONSTITUTION:An output of the A/D converter 11 is inputted to an amplification attenuator 13. Then the input signal delayed by a delay time with conversion at a delay circuit 12 is inputted to the amplification attenuator 13 at the same time and its output is inputted to an A/D converter 14. Then the output of both the converters is stored in a memory 15. The output of the converter 11 is inputted to a digital comparator 16 at the same time, and the comparator 16 compares it with the content of a register 17 and outputs a larger value to the register 17 as a maximum value. When the input system processing is finished, a controller 20 gives a command of normalization of the output (amplification attenuation rate) of the converter 11 to a correction circuit 18. The normalization is conducted by using the maximum value of the amplification attenuation rate of the register 17. The amplification attenuation rate subject to normalization is stored again in the memory 15 ane each input signal and each normalized amplification attenuation rate are multiplied by the correction circuit 18 so as to correct the input signal.
