Title: Magnetic tape recording and reproducing device
Inventor: SHIROSHITA KENJI
IPC: G11B5/09
Filed: 1988-05-12
Abstract: PURPOSE:To easily detect the shape of a reproducing spectrum and to perform the optimum equalization by recording a pilot signal having a specific frequency spectrum and in which prescribed data strings are combined on a part of a recording track. CONSTITUTION:The pilot signal centering the carrier frequency FC of a QPSK signal and having a frequency spectrum (FC+ or -1/8FCL) with level symmetry for a data clock FCL is recorded on a part of the recording track cyclically and alternately. As the pilot signal, the data string in which the data string '0111' and the one of '0110' type are combined is used. It is possible to recover an audio signal correctly by detecting the peak value (FC+ or -1/8FCL) of two signals by the characteristic control part of an on-going reproducing equalizer and controlling the reproducing equalizer so as to conform the levels of the two signals to each other.

Abstract: PURPOSE:To prevent the occurrence of vibration or noises and to make it possible to prevent the settlement of a peripheral ground or liquefaction by partitioning a poor subsoil into a specific size with an underground wall, and pressurizing the inside of the partition to lower ground water down to a specific depth. CONSTITUTION:A poor subsoil 1 forecasting the occurrence of liquefaction is partitioned with an underground wall 2 to construct a grid partition 3. At that time, a gravel mat 4 spread with crushed stone, etc., having high precentage of void is formed on the upper surface of the partition 3, and it is coated with an upper lid 4a in order to easily apply pressure. After that, air pressure is applied to the gravel mat 4 with a compressor, and pressure in the partition 3 is increased up to a specific value. The specific value is set based on pressure of a portion of difference in above sea level between ground water level W of the outside of the partition 3 and the lower end of a stratum G forecasting the occurrence of liquefaction in advance. As a result, ground water level W is lowered down to the lower surface of the stratum G, and the poor subsoil 1 is in a complete unsaturation state to eliminate the occurrence of excess pore water pressure.

IPC: A61B5/145
Filed: 1997-04-22
Abstract: PROBLEM TO BE SOLVED: To enhance reliability of a safety operation due to CO gas intoxication in exhaust gas exhausted from a combustion equipment. SOLUTION: CO concentration in exhaust gas of a combustion equipment is detected by a CO concentration detector 12 at each unit detecting time (t). A ratio calculating integrator 13 obtains a time T when blood hemoglobin CO concentration becomes a dangerous reference concentration with given data as a person is exposed with detected CO concentration. A value of a ratio t/T of the time (t) to the time T obtained by the data is calculated as a weighted ratio, and the weighted ratios are integrated at respective unit detecting times (t). An alarm output unit 14 compares the integrated value TR of the weighted ratios with a previously given alarm reference value, and outputs an alarm signal when the value TR arrives at this reference value. The safety operation such as a combustion stop is conducted according to the signal.
