Title: Erasing method of magnetic recording medium
Inventor: SHIROTA YOSHIROU
IPC: G11B5/024
Filed: 1981-09-28
Abstract: PURPOSE:To eliminate the deterioration of the distortion factor for the recording and reproducing waveforms, by applying an erasing magnetic field by the 2nd erasing head and in the direction opposite to the residual magnetization to eliminate substantially the residual magnetization after generating the residual magnetization by applying a saturated magnetic field by an erasing head. CONSTITUTION:The two erasing heads 1 and 5 are set side by side and in the travelling direction of a magnetic recording medium 2. A saturated magnetic field is applied to a magnetic layer 3 of the medium 2 by the head 1 in order to generate the residual magnetizaton. Then an erasing magnetic field -Hd is applied by the head 5 in the direction opposite to the above-mentioned residual magnetization in order to eliminate substantially the residual magnetization. For instance, the head 1 uses a permanent magnet type erasing head, and the head 5 uses a DC erasing head respectively. At the same time, the DC current to be applied to these head is controlled so as to approximate the magnetic field -Hd to the nonhysteresis region of the medium 2.

Title: Maximum likelihood estimate device
Inventor: SHIINO HARUHIRO
IPC: H03M13/39
Filed: 1991-06-25
Abstract: PURPOSE:To estimate a transmission symbol correctly with the Viterbi algorithm by preventing an estimate of an impulse response of a transmission line receiving a data part from being deviated timewise. CONSTITUTION:A path in which a state of a known data block in a TDMA frame is taken is calculated in advance based on the known data and stored in an intermediate path storage means 48. When a pathmetric of the state for the known data block is calculated, an intermediate path processing means 47 replaces a pathmetric of a path dissident with a path stored in the storage means 48 among available paths from one preceding time state with a very small value and gives the result to a path selection means 43. Thus, the path for the known data block is converged automatically to a correct path. An estimate transmission system series obtained from the converged path for the known data block is given to a transmission line estimate section 50A as the 2nd training series and the estimate section 50A estimates again the impulse response of the transmission line for the known data block.

Title: Dihydric system of antenna device system
Inventor: YABE NORIO
IPC: H01P1/30
Filed: 1979-11-30
Abstract: PURPOSE:To reduce the power consumption of the antenna station of a microwave communication system and to automate the system fully, by filling a feeder with dry air at any time by making use of natural air circulation. CONSTITUTION:The uppermost part of feeder 3 is linked to steam tank 5 via pipe 7a. On pipe 7a, a nonreturn valve is provided which permits a fluid to pass through it only from feeder 3 to steam tank 5. Steam in feeder 3 moves up because of a difference in density based upon the molecular weight in the air and flows into steam tank 5 by way of nonreturn valve 4. This tank 7, receiving solar light as shown by arrows 5, increases the temperature of the internal highly-humid air to increase in pressure. Then, the highly-humid-air is supplied into drier 8 via pipe 7b and, after being dehumidified there, fed into feeder 3. Thus, the electric power consumption of the antenna station of the microwave communication system can be reduced and it can be automated fully by filling feeder 3 with dry air at any time.

Title: Latent heat recovery heat source machine and method for controlling its combustion
Inventor: NAKAMURA YOSHITAKA
IPC: F24H1/10
Filed: 1997-05-29
Abstract: PROBLEM TO BE SOLVED: To simultaneously enhance a heating efficiency and combustion efficiency by controlling so that combustion output of a gas burner rises when circulating water is lowered from a set temperature and falls when it is raised. SOLUTION: A main heat exchanger 1a gives sufficient temperature for heating to circulating water by combustion heat of a gas burner 3, sends it to heating radiator side by a warm water pump 8, and returns the water cooled thereby to a sub-heat exchanger 1b. Here, it is brought into contact with exhaust gas, and condensed heat is absorbed by the water. That is, since the water absorbs heats in both the exchangers 1a, 1b, its heat efficiency is raised. And, a condensing temperature of the water is measured by a sensor 9. When it is a set temperature (e.g. 35 to 40 deg.C) or lower, the combustion of the burner is continued. If it exceeds 40 deg.C, operations of the burner 3 and a fan 5 are stopped under the control of a controller 20. Thus, heating and combustion efficiencies can be improved.
