Title: Inkjet printer
Inventor: KUROTORI TSUNEO
IPC: C09D11/02
Filed: 1989-11-30
Abstract: PURPOSE:To enhance the high-speed catch-up efficiency and to obtain superior fixedness to a general paper by combining a fixing apparatus comprised of a heating roller for fixing a printing surface or a heating plate, and a pressuring roller with an inkjet apparatus. CONSTITUTION:The ink in a liquid chamber 2 is jetted out from nozzles of a nozzle head 1 and printed onto a recording paper P. The recorded paper P is immediately introduced between a heating roller 4 and a pressuring roller 5 arranged in pressed contact with the heating roller 4, so that the printing surface is thermally fixed by the heating roller 4 which is heated by a heater 3. A fluoric resin is coated on the surface of the heating roller 4 so as to improve the releasing efficiency. If an oil ink is used, nozzles are not clogged even at the high density printing time. Moreover, if a thermally crosslinking resin is employed for the component of the ink, not only the coupling force among the ink, but the coupling force of the ink to the paper are increased since the heat is added at the fixing time. Therefore, the adhesion of the ink to the surface of the heating roller or heating plate can be prevented. Accordingly, recording of good quality by fixing and without the printing offset is achieved.

IPC: H01J23/20
Filed: 1994-12-15
Abstract: PURPOSE: To control an interference vibration by providing a high-frequency buffer material near a DC power supply conductor. CONSTITUTION: A device which composes an input resonator cavity 2 has a DC voltage connection supporter 10. A grid connection conductor 11 in contact with a metallic toroidal disk 8 passes the supporter 10 and is connected with a DC voltage conductor 12. A part of the conductor 11 is surrounded by a high-frequency buffer material 14 such as a ferrite ring through an insulating coating 13. As a result, electric energy of a high-frequency electric field is absorbed by a magnetic resonance or a dielectric loss in the material 14. Therefore, an interference vibration generated in relation to an inductance of the conductor 12 is suppressed.

Title: Manufacture of composite magnetic material
Inventor: ONO NORIHIKO
IPC: B29C45/26
Filed: 1997-11-13
Abstract: PROBLEM TO BE SOLVED: To obtain a desired degree of orientation under a simple structure and meet the requirements of even a composite magnetic material with generation sources for a low-frequency noise and a high-frequency noise generation source adjacent to each other, at a low manufacturing cost by forming slits in the specified part of a mold used for injection molding, and orientating the composite magnetic material. SOLUTION: After placing a lid from above a mold 11, a material constituting a composite magnetic material is poured into the grooves of the mold 11 from a nozzle 21. In addition, a magnet for applying a magnetic field for orientation is arranged on the circumferences of a low-frequency part and a high-frequency part which are located at the lower side of the mold 11. In detail, the magnet is embedded into the grooves formed on the circumferences of the low-frequency part and the high-frequency part located at the lower side of the mold 11. Further, slits 31 are formed in these grooves. A high degree of orientation over or under the degree of orientation of 3.9 is obtained by using the described magnetic field orientation. Therefore, even when the required magnetic material is of such a construction that the noise generation sources for the low-frequency and the high-frequency noise are adjacent to each other, it is possible to meet the requirements of this magnetic material by molding a single composite magnetic material with a partially divided noise generation source.

Abstract: PURPOSE: To reduce the number of working processes and improve the productivity of a vacuum induction melting furnace by providing a through pipe which moves in the vertical direction above a crucible and a gas circulating device, such as the turbo-fan, etc., and adding a through pipe which communicates with a vacuum tank and a circulation type forcibly cooling means, such as an inert gas cylinder, etc. CONSTITUTION: After the molten metal in a carbon crucible 1 in a vacuum induction melting furnace is tapped by tilting the crucible 1, the pressure in a vacuum tank is raised to a value slightly lower than the atmospheric pressure by introducing the gas in an insert gas cylinder 15 to the tank through a pressure reducing valve 16 and a solenoid valve 12. While the inside of the vacuum tank is maintained at the pressure, the crucible 1 is forcibly cooled by injecting the gas into the crucible 1 by lowering a vacuum through pipe 11 and operating a turbo-fan 14. The gas which absorbs the heat in the crucible 1 is forcibly cooled while the gas passes through the wall of the vacuum tank which is cooled with cooling water, again sucked to the fan 14, and repeatedly circulated.  The through pipe 11 can be moved in the vertical direction and does not hinder the melting work and tilting work, because the pipe 11 is pulled up during the work.

Title: Analog/digital converter
Inventor: MIKI TAKAHIRO
IPC: H03M1/44
Filed: 1988-12-12
Abstract: PURPOSE:To reduce both the characteristic error and the power consumption of a circuit by outputting the result obtained by subtracting the double input value from the full scale value in case the double input value is smaller than the full scale value and then outputting the result obtained by subtracting the double input value from the double full scaler value in case the double input value is larger than the full scale value. CONSTITUTION:A current comparator 16 compares the current value double as much as an input current with the drain current value (reference current) of an n channel MOS transistor TR 10. When the double input current value is smaller than the reference current value, a TR 15 is cut off, but the TR 15 is energized in the inverse case. In the former case, the current value obtained by subtracting the double input current value from the drain current (reference current) of an n channel MOS TR 11a is obtained via a current output terminal 6. While in the latter case, the current value obtained by subtracting the double input current value from the sum of the drain currents (double reference current) of both TR 11a and 11b is obtained via the terminal 6 respectively.
