IPC: G11B5/39
Filed: 1993-01-29
Abstract: PURPOSE:To restrain a Barkhausen noise by a method wherein a magnetic domain is oriented stably by a simple constitution and even under a low current. CONSTITUTION:In the MR head, a bias conductor 2 to which a bias current (i) used to apply a bias magnetic field is supplied is formed in an MR element 1 as a thin film. In the MR head, the surface of the MR element 1 its polished and ground along the direction (the bias direction) of the bias current (i) flowing to the bias conductor 2. Then, a wood grain-shaped rough surface 3 in which mountain peaks are arranged in a direction perpendicular to the bias direction is formed on the surface of the MR element 1. In this case, the surface roughness Ra of the rough surface is set at 0.5nm<=Ra<=2.0nm.

Title: Facsimile code converter
Inventor: HIROKAWA SUKEYUKI
IPC: H04N1/413
Filed: 1991-02-27
Abstract: PURPOSE:To reduce the cost of the converter by using hardware processing to convert a picture data into an intermediate language and using software processing to generate a coding data from the intermediate language. CONSTITUTION:An encoding arithmetic section 5 uses an address controller 4 so as to control a line memory 1 thereby checking the state of picture elements sequentially and when a change point is detected, an intermediate language is generated from the information. Upon the receipt of this informaition, register group 6 informs the detection of the change point to a microcomputer processing circuit 9. The circuit 9 references a coding table corresponding to the mode to generate a coding data from the intermediate language. Thus, the cost of the converter is reduced without need of a high speed microcomputer and a memory of large capacity.

Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of vibration during the driving of an optical pickup by providing a contact part and an elastic engaging member in the optical pickup and making them in contact with each other so as to hold a lead screw. SOLUTION: A contact part 29a and an elastic engaging part 39 provided on one side of the pickup chassis 29 of an optical pickup 20 are made in contact with each other so as to hold a lead screw. Thus, a gap is formed with the lead screw 30 of the pickup chassis 29 whose other side is supported movably by a guide shaft 31 via a pair of bearings 42a and 42b. Thus, since the play of each component is eliminated at the time of driving the optical pickup 20 and any vibration is not caused, accuracy for supporting the optical pickup 20 is improved. Further, by forming a limiter in the periphery of the engaging part of the elastic engaging part extending in the axial direction of the lead screw 30, the engaging part is prevented from being disengaged when the lead screw 30 is rotated at a high speed.

Abstract: PURPOSE:To execute easily and quickly focusing of a fixed-focus camera and an adjustment of an inclination, by providing a projecting device on two positions which is shifted from an optical axis of the camera, and making plural projected image conform on the focusing surface. CONSTITUTION:The titled device is constituted so that LED light sources 2, 2' for positioning are placed on both sides of an optical axis of a fixed-focus camera 1, and a rectangular image is projected on a focal plane 4 by projection lenses 3, 3'.

In this regard, when blue and green are used for three LEDs, the superposed part becomes white and can be discriminated easily. Therefore, focusing of the camera and its inclination can be adjusted easily and quickly.

IPC: B60K17/24
Filed: 1996-01-26
Abstract: PROBLEM TO BE SOLVED: To prevent noise and vibration from transmitting to a vehicle by avoiding the fluctuation of the rotational balance of a propeller shaft for vehicle. SOLUTION: The axis of rotation on the other end side of a propeller shaft 1 is fixed by supporting an outer circumferential part of the other end part of the propeller shaft 1 by a differential carrier 19 through a metal bush 21.

Title: Laser-processing method for use in rotary bodies
Inventor: MIYAUCHI TAKESHI
IPC: B23K26/18
Filed: 1978-03-24
Abstract: PURPOSE:To eliminate the adhesion of unstable substances to the surface of a rotary body after laser processing by forming an oil membrne over the surface of the rotary body before applying laser light thereto. CONSTITUTION:The surface of a rotary body 4 is coated with oil to form an oil membrane 8 thereon. Then, laser light is applied to the rotary body 4 to bore a processing hole at a processing section 5. At the time, the end of a hot and unstable peripheral projection 6 and scattered substances 7 come to contact with the said oil membrane 8. The oil membrane 8 evaporates instantly, and repels explosively the scattered substances 7. The end of the projection 6 disappears, and the scattered substances 7 do not adhere to the rotary body. Thus, a stable projection 9 alone is left at the processing section.

Title: Apparatus and method for inspection of smooth face of sample
Inventor: HENZLER MARTIN
IPC: G01N21/94
Filed: 1998-02-16
Abstract: PROBLEM TO BE SOLVED: To provide an apparatus and a method in which the effect of a treatment correction applied to a part in which the scattering of light on the surface of a sample has been recognized to be remarkable can be compared and inspected easily by scanning the surface by converged laser ray, and detecting the scattered light reflected during the scanning. SOLUTION: The beam 4 of a laser 5 is focused on a sample 9 on a sample holder 16 inside a chamber 2 through a lens 8 via a coupling mirror 6 and a polarizing mirror 7. Scattered light is reflected in the range of a solid angle of, e.g. 3 to 15 deg. with reference to a beam of specularly reflected light, and it advances to a detector 11 in parallel with the lens 8. A diaphragm 13 cuts off a dispersing external radiation, and the scattered light is focused on a pin diaphragm 15 by a lens 14 so as to reach a light detecting mechanism finally. When a defect which scatters light exists on the surface of a sample, a scattered-light signal in which a specific x-position and a specific y-position are designated is transmitted. After that, a remarkable region is separated with high precision, and it is inspected more precisely by using microscopy.

Title: Video signal processing system
Inventor: SUZUKI YOSHINORI
IPC: H04N5/93
Filed: 1991-02-27
Abstract: PURPOSE:To prevent a reproduced picture from being vertically moved by complementing line signals with remaining line signals when one part of the line signals is lost in the line signals of mutually adjacent three lines at least. CONSTITUTION:In respect to the line signals for the mutually adjacent three lines in an interface system at least, a weighted average signal is obtained by multiplying and adding mutually different coefficients according to whether the field of the video signal is coincident with the odd/even number of a reference field. The average value of vertically displacing the weighted average line signal on the reproduced picture is set to be smaller than a 1/4 distance between the lines. When one part of the mutually adjacent line signals lost, the lost line signal is complemented with the remaining line signals by using switches 1, 3 and 4. Thus, the reproduced signal of a variable-speed reproduced video signal not vertically moved, the change of sharpness for each field is reduced, and the deterioration of the vertical resolution of the reproduced picture is reduced.

Title: Clamp control circuit
Inventor: TSUJI TOSHIAKI
IPC: H04N5/14
Filed: 1994-03-03
Abstract: PURPOSE:To improve the accuracy of clamping by changing clamp control of a MUSE decoder depending on a noise detection quantity. CONSTITUTION:In the clamp processing of a MUSE decoder, a clamp level control circuit 5 detects the difference of a clamp level from a reference level to control a clamp circuit 2. Furthermore, a control pulse generating circuit 7 generates a pulse to clamp an HD period based on a synchronizing signal detected by a synchronizing separator circuit 6 to control the clamp circuit 2. A time constant of a filter included in a clamp level control circuit 5 and a width of a pulse generated from a control pulse generating circuit 7 are controlled based on the output of a noise detection circuit 10. Thus, the response of clamping and suppression of flicker on a screen due to noise are made compatible with each other by controlling the time constant of the filter and pulse distortion for the HD period and fluctuation for each line due to noise are suppressed by varying the width of the pulse.
