Title: Treatment of halogen-based flame retardant-containing plastic
Inventor: INAGAKI YASUSHI
IPC: C08J11/18
Filed: 1997-01-06
Abstract: PROBLEM TO BE SOLVED: To provide a treating method capable of efficiently separating a halogen-based flame retardant contained in a plastic waste material, etc. SOLUTION: A plastic containing a halogen-based flame retardant is treated with an acid in an organic solvent and an ion group is introduced into a resin component to afford a water-soluble polymer and the halogen-based flame retardant is separated. Ion group is introduced into the resin component to afford the water-soluble polymer and the water-soluble polymer is transferred into a water phase by carrying out acid treatment of the plastic containing the halogen-based flame retardant in the organic solvent. On the one hand, in the halogen-based flame retardant, such introduction of ion group does not occur and the halogen-based retardant directly stays in the organic solvent phase in unreacted state. Consequently, the resin component is rapidly separated from the halogen-based flame retardant by separating the water phase from the organic solvent phase.

Title: Magnetic head
Inventor: KAMINAKA NOBUMASA
IPC: G11B5/127
Filed: 1984-01-05
Abstract: PURPOSE:To obtain a magnetic head where high-precision reproducing which is the condition of high-density recording is realized, by providing a return magnetic flux cancelling layer which faces a magnetic flux converging layer through a space and has both end parts connected electrically to this magnetic flux converging layer. CONSTITUTION:A groove is provided on a substrate 7 consisting of ferrite or the like, and a nonmagnetic material 8 is packed in this groove, and the first nonmagnetic insulating layer 9 is formed on the surface, and an MR element 10, a conductor layer 11, and a magnetic flux cancelling layer 12 are formed on the insulating layer 9. Next, the second nonmagnetic insulating layer 13 is laminated, and a magnetic flux converging layer 14 is so arranged that it overlaps the MR element by 5-10mum. Since the magnetic flux coverging layer 14 and the magnetic flux cancelling layer 12 are brought into contact with each other physically and electrically in both ends of a track width TW of the magnetic flux converging layer 14 because a through hole or an exposed part exists in the second nonmagnetic insulating layer 13, the magnetic flux fed back on the way of the magnetic flux converging layer 14 is cancelled by the reverese magnetic flux due to a counter electromotive force generated by a one-turn ring formed with the converging layer 14 and the cancelling layer 12.

IPC: B41J2/335
Filed: 1989-01-04
Abstract: PURPOSE:To minimize a difference in applied voltages caused by printing positions by connecting a thick-film conductor part made of a good conductor to a thin-film common electrode which directly supplies a printing current to thin-film heating resistors. CONSTITUTION:A resistant layer 2 is formed on an alumina substrate 1, and thereon an aluminum conductor layer 3 is formed. Thereafter, a patterning is performed using a photoresist, and thin-film heating resistors 4 made of a part of the resistant layer 2 and a thin-film common electrode 3a and thin-film discrete electrodes 3b made of the aluminum conductor layer 3 are formed by selective etching. After the photoresist is removed, one area of the electrode 3a is masked with a photoresist and thereon a nickel-plated layer 6a is formed. After non-conductor part of the substrate 1 is activated, the plated layer 6a is further formed on the side and rear faces. A copper-plated layer 5 is formed on the plated layer 6a and, thereon, a nickel layer 6b is plated. A wear-resistant layer 7 made of a silicon oxide film is formed, thereafter being coated with an insulating resin film 8. In this manner, voltage values to be applied to the heating resistors according to printing positions can be remarkably uniformized.

Filed: 1981-01-08
Abstract: PURPOSE:To obtain the automatic process of yarn-stretching for drawing up the yarn mounted on a waste roller to an end of an empty bobbin for winding. CONSTITUTION:When a shaft 35 is rotated clockwise, a roller chain 33 inserted into a square pipe 34 is driven via a sprocket 36, and a yarn Y6 running between an introduction guide 14 and a winding position guide 16 is scooped up by a yarn-stretching guide 31 equipped on one end of the chain 33 via a guide holder 32. The yarn Y6 is drawn up to the end face of a bobbin B mounted on a cradle arm 44 in accordance with the curvature of the square pipe 34 previously fixed. Consequently, the relation of the relative position between a yarn-stretching  ratchet wheel 30 provided on a bobbin bearing and a yarn-stretching guide 31 is kept constant, and the success rate of yarn-stretching onto the bobbin B is greatly improved. Besides, the contact and the interference between the yarn- stretching guide 31 and ratchet wheel 30 can be prevented for improving the protection and the stability of a yarn conveyor greatly.

Abstract: PURPOSE:To supply a clock signal even when a fault takes place in the clock generating circuit without causing the performance deterioration or malfunction due to the difference of phases of clock signals by providing a clock generation circuit to each large scale circuit integration and controlling an output buffer to transfer the clock signal. CONSTITUTION:When a test mode signal A21 is at an L level, an L level is given to an output buffer 26 and an H level signal inverted by an inverter 22 is given to an output buffer 23. Thus, the clock generated by a clock generation circuit 2 of a large scale integrated circuit I1 is fed to the large scale integrated circuit I1 as a clock signal I3 via an input buffer 24 from the output buffer 23. Simultaneously, the clock is fed into a large scale integrated circuit II5 via an input buffer 25 in the large scale integrated circuit II5 from the output buffer 23 as a clock signal II7. On the other hand, when the test mode signal A21 is at an H level conversely, an H level is fed to an output buffer 26 and an L level signal inverted by the inverter 22 is fed to the output buffer 23.

Title: Level alarm circuit
Inventor: AKAHA HIDEKI
IPC: H04L27/38
Filed: 1986-01-07
Abstract: PURPOSE:To send surely an alarm even when inputting a non-modulation wave of a frequency having a predetermined level or over by providing a band stop filter of a center frequency between a reception section and a level alarm circuit. CONSTITUTION:The band stop filter 4 whose center frequency is f0 is inserted between the reception section 1 and the supervisory circuit 3. A spectrum of a multi-value orthogonal amplitude modulation wave fed to the supervisory circuit 3 is as shown in a figure (a), where the f0 component is eliminated, but since the peak level is unchanged, the DC output voltage is unchanged and no alarm is sent. In case of non-modulation as shown in a figure (b), since the wave is stopped by the filter, the input to the level alarm circuit is 0 and an alarm is sent from the supervisory circuit 3. Thus, a faulty location is troubleshooted in a shorter time.
