Title: Protective circuit
Inventor: JIYON BARETSUTO JIYOOJI
IPC: H03F1/52
Filed: 1995-08-02
Abstract: PROBLEM TO BE SOLVED: To prevent a transistor for an amplifier from being broken when a dynamic converging circuit gets out of order. SOLUTION: An active pull-up circuit 105 which is coupled with a high- voltage source generates an operating voltage. An amplifier 106 for a dynamic convergence modulated signal has low-voltage transistors Q103, Q104, Q105, and Q106 which are driven with the operating voltage and coupled as Darlington pairs in differential constitution. The low-voltage transistor Q104 is coupled directly in push-pull constitution between a resistance R140 in the pull-up circuit and the ground. A fault state of the push-pull constitution breaks the resistance to cause an open state. A switch like a Zener diode CR104 is coupled between one low-voltage transistor of the amplifier and the ground. This switch prevents a reverse breakdown of a transistor until the resistance is broken if a fault occurs.

Abstract: PURPOSE:To surely open or close contacts by forming the rotation stop section of a movable contact plate on a cross bar so that the other end of a contact spring can move only the side exciting the movable contact plate in the closing direction. CONSTITUTION:When an overcurrent flows between contacts 7 and 13, a movable contact plate 12 is rotated centering a support shaft 15 by an electromagnetic repulsive force due to the overcurrent in relation with a contact spring 19 into contact with the rotation stop section 18d of a cross bar 18, and an arc 1 is generated across contacts 7 and 13 when the movable contact 13 is separated from the fixed contact 7.

Filed: 1984-10-29
Abstract: PURPOSE:To make stable a flying condition of ink drops by providing an electrode with an ink flying space between a needle and a printing paper. CONSTITUTION:The arrangement of a needle 24, printing paper 12 and electrodes 47 is such that the electrodes 47 are disposed with a flying space 47a between the needle 24 and the recording paper 12. In such a construction, the ink is flown relatively straight by a resultant force of its inertia and attraction force of a line of electric force, since the ink 43 has an initial velocity in a moment it is separated from the needle 24. Therefore, the adhering position of the ink to the recording paper 12 is not shifted from the center between the electrodes 47, and specially it does not come into collision with the electrodes 47 directly. Moreover, no adverse effect is exerted upon the flight of the ink 24, since there is no concentration of the line of electric power, as the edges of the electrodes 47 are formed roundly.

Abstract: PURPOSE:To facilitate the correction of exposure irregularities and the control of the amount of exposure, by controlling both the incident position and the incident angle of a laser beam. CONSTITUTION:A laser beam 20, which is emitted from an excimer laser head 1, passes through a position sensor 4 and a position sensor 5. Then the beam is reflected with mirrors 6, 7 and 8 and reaches a wafer 12 through a reticle 9 and a projecting lens 10. A stepper optical system comprising the parts 4-10 is fixed as a unitary body with a lens supporting stage 11, which is fixed to a stepper surface plate 15. Therefore the relative positions in the stepper optical system are substantially unchanged. The wafer 12 is sucked on a wafer chuck 13 with vacuum. The wafer chuck 13 is fixed to an X-Y stage 14, which is provided on the stepper surface plate 15. In the ordinary case, reduced patterns of several tens of shots are transferred on the wafer. Therefore, the X-Y stage 14 is moved in the direction X or Y, and the laser light is emitted. In this way the transfer is repeated.

Filed: 1985-10-12
Abstract: PURPOSE:To efficiently disperse a magnetic paint by dispersing a mixture composed of a ferromagnetic powder, a coupling agent and a solvent after it is aged for the specified time after a mixing processing. CONSTITUTION:A magnetic paint forming material composed of the magnetic layer forming material of a magnetic recording medium and the solvent at least including the ferromagnetic powder and the linking agent are mixed, the mixture is adjusted, and next, after the mixture is aged at least for five hours, the mixture is dispersed, for example, by the sand grinder, etc. By such an operation, the dispersing property of the ferromagnetic powder, etc., is increased, and the dispersing process is efficiently executed. Especially, even at the time of using the fine particle ferromagnetic powder, the long period is not necessary, the satisfactory dispersion is obtained, and for such a reason, the damage of the ferromagnetic powder can be decreased at the dispersing process. Consequently, various characteristics such as the electromagnetic converting characteristics, etc., are satisfactorily held. When the time is sufficiently spent for the dispersion, the association body such as the secondary particles and the tertiary particles is decreased in the paint, and therefore, the uniformity and the surface smoothness of the magnetic layer formed by using these are satisfactory and the obtained magnetic recording media have the excellent electromagnetic converting characteristic.

Abstract: PURPOSE:To retreat a projecting portion from a locking hole without using any tool so as to enable an accessory to be attached to and removed from a lighting fixture main body by pushing a handle inward. CONSTITUTION:To exchange a fluorescent lamp 2 for a new one, a handle 23 is pushed in the direction indicated by the arrow A and then a projecting portion 22 is disconnected from a locking hole 6, so that a louver 7 can be rotated downward about that portion of the louver 7 where the end of a rotation supporting member 15 is made to abut on the bent piece 4 of a lighting fixture main body 1. In this case, the rotation supporting member 15 would not be disconnected from a square hole 5 because the end of the member 15 is bent at an acute angle. To mount the louver 7 on the lighting fixture main body 1, the louver 7 is rotated upward with the handle 23 pushed inward and then the handle 2 is released, so that the projecting portion 22 can be engaged in the locking hole 6 of the lighting fixture main body 1 by means of the elasticity of an elastic piece 21. The louver 7 can thus be attached to and removed from the lighting fixture main body 1 very easily without using any tool.

Title: Thin-film magnetic head and its production
Inventor: SAITO MASAJI
IPC: G11B5/31
Filed: 1995-09-05
Abstract: PROBLEM TO BE SOLVED: To make it possible to surely and tightly adhere antiferromagnetic layers to free magnetic layers in both side parts where a track width is opened. SOLUTION: The first antiferromagnetic layers 10 are formed on both sides where the track width (Tw) is opened on a lower gap layer 1. The free magnetic layers 3, nonmagnetic conductive layers 5, fixed magnetic layers 6 and second antiferromagnetic layers 7 are successively laminated thereon. Since the free magnetic layers 3 are formed after the first antiferromagnetic layers 10 are formed, the tight adhesion of the first antiferromagnetic layers 10 and the free magnetic layers 3 is sure. The electric resistance is changed when the direction of the magnetization of the free material layers 3 is changed by external magnetic fields, by which the external magnetic fields are detected but the free magnetic layers 3 are made into single domains in an X direction by the antiferromagnetic layers 10 and, therefore, Barkhausen noises are decreased.

IPC: C23F4/00
Filed: 1998-08-12
Abstract: PROBLEM TO BE SOLVED: To provide a low frequency etching method where improvement is performed in such a manner that ununiformity of a high spatial frequency is reduced. SOLUTION: A specified output of a low frequency signal source 12 constituting a main energy source for etching a wafer, and a specified output of a high frequency signal source 24 whose frequency is lower than that of the low frequency signal source 12, are coupled and supplied across a pair of electrodes, for plasma etching. By using a frequency trap of a coupled circuit which is tuned to a frequency of a high frequency signal, the high frequency signal from the high frequency signal source 24 is prevented from being fed back to the low frequency signal source 12. By using capacitive means of the coupled circuit, the low frequency signal is prevented from passing the frequency trap and reaching the high frequency signal source. Thus, uniformity of etching is improved.
