Title: Magnetic head
Inventor: MATSUDA TAKAYA
IPC: G11B5/127
Filed: 1987-09-30
Abstract: PURPOSE:To reduce the reading error of the output of a recording and reproducing head by having a different thermal expansion coefficient at a sealing material to bond the gap with an erasing head for a recording and reproducing head. CONSTITUTION:When a glass having a thermal expansion coefficient smaller than the thermal expansion coefficient of a recording and reproducing core 5 of a ferrite material is used as a sealing agent, the effective permeability of the recording and reproducing core 5 is raised, and when the glass having the thermal expansion coefficient larger than the thermal expansion coefficient of the recording and reproducing core 5 is used, the effective permeability of the recording and reproducing core 5 is lowered. The relation is in the same way applied to an erasing core 11 of an erasing head 3 and a sealing material 16. Consequently, when the effective permeability of the erasing core 11 is smaller than the recording and reproducing core 5 at the extent in which a trouble does not occur for the erasing action of the erasing head 3 and the off-track occurs at the time of recording and reproducing, the magnetic flux picked up from the peak of the recording track by the erasing head 3 is reduced, the magnetic flux to flow in the erasing core 11 is reduced, and therefore, the leakage flux to enter the recording and reproducing core 5 can be prevented and the reading error of the reproducing output from a reproducing and recording head 2 can be prevented.

IPC: H01L21/822
Filed: 1997-09-09
Abstract: PROBLEM TO BE SOLVED: To prevent a short circuit between electrodes of a capacitor element, by providing an insulating film fluidized at lower temperature than that of electrodes of the element between the electrode and a dielectric film. SOLUTION: A capacitor element C has a laminated structure obtained by sequentially laminating an electrode 3, dielectric film 5 and electrode 7 on a surface of a field insulating film 2, and a large capacity of, for example, several hundreds [pF]. An insulating film fluidized at lower temperature than those of the electrodes 3, 7 is provided between the electrode 7 and the film 5 of the element C. A film 6 is formed of a BPSG film deposited, for example, by a CVD method. Since the BPSG film is changed at glass transition temperature, i.e., fluidizing temperature according to implanting amounts of boron (B) and phosphorus (P), the BPSG film can be fluidized at lower temperature than those of the electrodes 3, 7 made of a polycrystalline silicon films in which boron is implanted by controlling the implanting amounts of boron (B) and phosphorus (P).

Title: Device for draining hydraulic tested pipe
Inventor: NAGAI AKIRA
IPC: G01M3/00
Filed: 1993-09-30
Abstract: PURPOSE:To prevent the flowing of water to the lower outer surface of a pipe by providing a guide member, which is in contact with the lower edge of the opening end of the pipe and guides the water in the pipe to the lower side. CONSTITUTION:When the hydraulic test is finished, both surface plates of a pipe 10 are removed. The water in the inside is drained into a water receiving pan 24 through a receiving port 12 and the opening end of an inserting port 14. At the same time, the pipe 10 is moved to a water draining position 20 with a truck 22. When the pipe reaches the position 20, the pipe 10 is slightly lowered by the truck 22, and the lower edge of the opening end of the inserting port 14 comes into contact with the vicinity of an apex 34 of a triangular guide member 30. Then the drained water from the opening end of the inserting port flows through the member 30. The receiving port 12 is lifted by one pipe receiving stage 28. The pipe 10 is inclined so that the side of the inserting port 14 becomes lower. Even if the draining advances and the flowing force becomes weak, the drained water is positively guided into the member 30 by providing the member 30 in this way. Therefore, the flowing of the water to the lower outer surface at the opening end can be positively prevented.

Title: Petroleum warm air heater
Inventor: ISHIMURA HIROYUKI
IPC: F24H3/02
Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To safely control a heater when a discharge amount of a fuel is changed owing to clogging tar in a calibrator or a nozzle with use of a modified lamp oil and to a trouble of a solenoid pump. SOLUTION: There is estimated a difference Q3 between an actual reduction amount Q1 of a lamp oil in a cartridge fuel tank 3 per unit time estimated on the basis of a signal of an oil amount detector 4 and a calculated fuel discharge amount Q2 per unit time of the solenoid pump estimated on the basis of a power supply rate and power supply time to the solenoid pump 7. When the estimated difference Q3 is smaller than a threshold value B among threshold values A, B, C, and D satisfying a relationship A<B<0<C<D but is larger than the threshold value A or when the same is larger than the threshold value C but is smaller than the threshold value D, a failure display 13 is driven without interrupting heating operation.  In contrast, when the difference Q3 is smaller than the threshold value A or larger than the threshold value D, the heating operation is interrupted and the failure display is driven. Thus, safety control and failure informing of the heater are securely achieved.

Title: Method of eliminating oil mist in centrifugal compressor
Inventor: MIDORI MIKIO
IPC: F04D25/02
Filed: 1984-11-21
Abstract: PURPOSE:To improve self exhaust functions by installing air vent pipes at a positive pressure part within a gear case and eliminating oil mist through the utilization of changes in air pressure within the gear case owing to the rotation of gears. CONSTITUTION:When an accelerating gear 2 is revolved, centrifugal power generated on the surface of the gear 2 owing to its rotation causes negative pressure around a shaft seal part 5 and positive pressure in other parts in a gear case 1. Accordingly, the parts where air vent pipes 9a, 9b are formed come to have positive pressure, and oil mist is discharged from the pipes, while negative pressure in the gear case is maintained, so that oil mist 6 does not leak from the shaft seal part 5. Thus, self oil mist discharge functions of the compressor can be improved.
