Title: Method and apparatus for information recording
Inventor: YOHANESU HENDORIKUSU MARIA SUP
IPC: G11B13/04
Filed: 1988-12-13
Abstract: PURPOSE: To reduce write-in noise by forming radiation as a radiation pulse, minimizing a time interval between the reversing moment of the magnetic field direction and the ending moment of the radiation pulse, sufficiently reinforcing the magnetic field against the part heated at the end of the radiation pulse and magnetizing in a prescribed direction. CONSTITUTION: An optical head 5 is provided with a semiconductor laser 8 driven by a signal Vr while a magnetic field modulator 7 modulates a magnetic field direction in accordance with a binary control signal Vm . The control signals Vr and Vm are derived from an information signal Vi through a synchronous circuit 9; the control signal Vr contains a pulselike signal controlling the intensity of a laser beam; and the control signal Vm alternates a magnetic field generating in a recording layer 4 by the magnetic modulator 7. Then, with a time interval minimized between the reversing moment of the magnetic field direction and the ending moment of the radiation pulse, the magnetic field is sufficiently reinforced against the part heated above the write-in temperature at the end of the radiation pulse, and magnetized in the direction prescribed by the magnetic field.  As a result, write-in noise is reduced.

Title: Optical coupling module
Inventor: KOTANI MITSUHIRO
IPC: G02B6/42
Filed: 1990-11-19
Abstract: PURPOSE:To make the electric conduction with another member sure by installing a projection or a level difference which is electrically integrally formed with the flange part of the module on a surface which contacts with another member in the case of attaching an optical coupling module to another member. CONSTITUTION:In the flange part 12, a contact part 3 is provided on the surface which contacts with another member in the case of attaching. As to the contact part 3, an annular rising part is formed around a screw hole 14, and in the case of attaching the optical coupling module to another member, the surface of the annular contact part 3 abuts on the member. Therefore, only the surface of the contact part 3 is ground in order to excellently keep the electric conduction of the optical coupling module. When the clamping force of a screw at the time of attaching is the same, contact pressure is remarkably higher than when the entire flange part 12 contacts, so that the conduction by the contact part 3 becomes surer.

Title: Method and equipment for measuring total loss of high reflectance mirror
Inventor: SEKIGUCHI HISAO
IPC: G01N21/55
Filed: 1992-11-24
Abstract: PURPOSE:To provide a total loss measuring system in which a laser tube is interposed between two plane mirrors, a ring optical path is established including a spherical mirror, intensity of transmitted light is measured by varying the intensity of laser beam and the position of the spherical mirror, and then sum of total losses of three mirrors is determined according to polynomial calculation. CONSTITUTION:Plane mirrors 21, 22 and a spherical mirror 23 are employed as mirrors to be measured and an He-Ne laser tube 24 is interposed between the mirrors 21, 22 thus constituting an equilateral triangular ring laser oscillator. Rotational angles of the mirrors 21, 22 can be read out on the scales of mirror holding mechanisms 28, 29 and incident angles of beam to the mirrors 21, 22 can be determined based on the readings. Incident angle to the mirror 23 can be calculated based on the incident angles of the mirrors 21, 22 thus determined and a scale on a moving rail 26. Transmission loss depends greatly on the incident angle whereas scattering loss scarcely depend thereon. Consequently, distance of the mirror 23 is varied to cause variation only of transmission loss, light transmitted through the mirror 21 is detected through an optical detector 32 every time when the transmission loss is varied, and the intensity of output light is approximated according to a polynomial thus calculating total loss.

Title: Numerical controller for distributed numerical control system and data transmission system using the numerical controller
Inventor: HARA KENJI
IPC: G05B19/418
Filed: 1994-12-16
Abstract: PURPOSE: To transmit the data to a specific secondary station at a speed higher than a simultaneous broadcast transmission period by starting a speed commander unit through a CPU part based on the data stored in a buffer register when a common frame is sent from an axis group management unit and a timer interruption signal is outputted. CONSTITUTION: An axis group management unit 110, i.e., a primary station carries out twice the continuous and successive transmission of data to the secondary stations after transmission of FF, i.e., the simultaneous broadcast and then transmits the data to a specific secondary station. When the primary station transmits the FF, each secondary station produces an interruption. Thus a CPU 1312 fetches the data written in a buffer register 1315 by the interruption of each secondary station and also outputs a start signal S1 to a timer circuit 1316 . The circuit 1316 sends a timer interruption signal S2 back to the part 1312 after 1ms. Receiving the signal S2, the part 1312 fetches the data from the register 1316 by the FF like an interruption.

Title: Magnetic head
Inventor: HORI TORU
IPC: G11B5/127
Filed: 1990-11-19
Abstract: PURPOSE:To obtain the magnetic head which hardly forms a pseudo magnetic gap by providing three layers; a layer of a soft magnetic film which contains at least nitrogen, a layer of a soft magnetic film which does not contain the nitrogen and a layer of a soft magnetic film which contains the nitrogen in the section where the soft magnetic films come into contact with ferrite. CONSTITUTION:The three layers; the layer 14 of the soft magnetic film which contains the nitrogen, the layer 15 of the soft magnetic film which does not contain the nitrogen and the layer 13 of the soft magnetic film which contains the nitrogen are provided in the section where the soft magnetic films come into contact with the ferrite at the head of an MIG type disposed with the soft magnetic films in the gap part of the ferrite cores. The nitrogen ligther than metal atoms diffuses from the nitrided layer 14 adjacent to the ferrite 12 further to the non-nitrided layer 15 adjacent thereto at the time of the heat treatment for gap formation. If the non-nitrided layer 15 pinched by the nitrided layer 14 is as thin as the nitrided layer 14, the compsn. of the metal is larger in the non-nitrided layer 15 by as much as the nitrogen-content and, therefore, the concn. of the nitride of the metal of the initial non-nitrided layer 15 is sufficiently larger than the concn. of the nitride of the metal of the first nitrided layer 14 and this nitride completely suppresses the diffusion of the elements, such as oxygen, from the ferrite 12. The influence of the pseudo gap is suppressed in this way and the degradation of the head magnetic characteristics is prevented.

Abstract: PURPOSE:To designate and write coordinates with high accuracy in accordance with an original video signal by setting a black level close to a white level of the video signal via a set-up amplifier when an optical signal detecting means like a light pen, etc., is used. CONSTITUTION:When a light pen 7 is used, a switch 2 is opened and an input video signal 1 is converted by a set-up amplifier 3 into such a signal having its black level set close to a white level.

In this case, an original picture is displayed as it is in a whitish color on the monitor 6 and can be detected by the pen 7 even at a part which could not be detected by the pen 7 because said part is too dark to be detected by the pen 7. Thus, it is possible to designate and write coordinates with high accuracy in accordance with an original video signal.
