Title: Semiconductor element
Inventor: IDE TETSUO
IPC: H01L23/48
Filed: 1986-08-28
Abstract: PURPOSE:To reduce the thickness of a protective material, to improve the adhesion of the protective material and a diode chip and to prevent the generation of bubbles in the protective material by making the area of a lead header section smaller than that of the chip. CONSTITUTION:The area of a lead header section is made smaller than that of a diode chip 1. Consequently, the header section 4 at the tip of a lead 3 is brazed with solder 2. When a protective material 5 such as JCR is applied onto the side surface of the diode chip 1, the protective material is pulled to the header section 4 having a smaller area and thickness thereof may be thinned, and the adhesion of the cured protective material 5 and the chip 1 is improved while the generation of bubbles in the protective material 5 is prevented. When the protective material is applied, turning a disk, on a side surface of which an applying material is attached, the disk is not brought into contact with the header section 4 and the chip 1 is not damaged, thus facilitating applying work.

Title: Film image reader
Inventor: SHIMADA YASUSHI
IPC: G03B27/62
Filed: 1991-08-13
Abstract: PURPOSE:To prevent interference fringes from being generated and to prevent a film from deflecting and to enable reading a sharp image by sandwiching a film original between two transparent plates and forming an uneven diffusion surface on the surface of at least one transparent plate which faces the film. CONSTITUTION:The film original 40 is set on a film scanner or film projector and read. At this time, the film original is sandwiched between the transparent plates 41, 42 made of glass, acryl, etc., to prevent the film from deflecting. The surfaces of the plates 41, 42 which face the film are made uneven to form diffusion surfaces. Consequently, no interference fringes are formed on the film original surface when the film is irradiated with light, and the film is prevented from deflecting, so the sharp image can be read even when formed on a CCD sensor through an optical system which has shallow focal depth.

Filed: 1988-08-17
Abstract: PURPOSE:To specify a fact that which cylinder's unit injection or the like gets out of order by discriminating a cylinder whose fuel injection quantity is unproper due to rotational unevenness. CONSTITUTION:When an engine is in an idling state, each time interval of adjacent claws is read by an Ne sensor at an electronic controller 1. Then, such a cylinder that a difference between these time intervals and the mean value exceeds the specified value is specified by a top-dead-center sensor 5. Next, stepping motors 12A-12D are rotated as much as the specified value in the specified direction, and an injection quantity to the cylinder corresponding to the maximum time interval is increased as much as the specified quantity, while an injection quantity of the cylinder corresponding to the minimum time interval is decreased as much as the specified value. Here, a counter of the cylinder whose fuel is increased or decreased in quantity is counted up, and in regard to the cylinder that the count value exceeds the specified value, it is displayed with a diagnosis lamp 1A. With this constitution, in the case where a unit injector 11 or the like gets troubled, a fact that which cylinder's is out of order can be thus specified.

Title: Composite thin film magnetic head
Inventor: FUKAZAWA TOSHIO
IPC: G11B5/31
Filed: 1989-08-04
Abstract: PURPOSE:To carry out good recording and reproduction by specifying the arrangement of the first to third upper magnetic layers constituting the upper magnetic layer and allowing the recording track width and reproducing track width to differ from each other. CONSTITUTION:The first upper magnetic layer 6 has a width identical to the reproducing track width TR. The upper magnetic layer 7 is formed on both sides of the magnetic layer 6 in its cross direction with a space 9 in between. The third upper magnetic layer 8 thinner than the magnetic layers 6 and 7 is formed in the space 9. Accordingly, the recording track width TW is equal to the sum of the widths of the magnetic layers 6-8, and the reproducing track width TR is equal to the width of the magnetic layer 6. Since the recording track width is different from the reproducing track width, the reproducing output is not decreased even if the traveling of a recording medium in recording deviated from that in reproduction. In addition, as the magnetic layer 8 is thin, reproduction is carried out at a low crosstalk level.

Filed: 1988-08-17
Abstract: PURPOSE:To stably and accurately measure landslide for a long time by filling the circumference of a deformation sensor using an optical fiber disposed in a flexible casing tube which is laid under the ground with a filling material having low strength. CONSTITUTION:The casing tube 3 is inserted into an excavated hole 4 which is excavated to the extent of depth which is sufficiently deeper than an expected sliding surface 11 in the ground 10. A material which is easy to be flexed so as to follow the movement of the ground is used for the tube 3. Then, the deformation sensors 1 using the optical fiber are held by spacers 2 which are arranged every prescribed interval and inserted into the tube 3. The spacers 2 can be inserted in the casing tube while they hold the sensors 1 at the prescribed intervals and they are shaped so that the tube 3 is not blocked and the injection of the filling material 5 having low strength is not interfered. Thus, the flexual rigidity of the tube 3 is not raised and the tube 3 is deformed by the movement of the ground caused by the landslide. Besides, the deformation of the tube 3 is propagated to the sensors 1 through the filling material 5.

Abstract: PROBLEM TO BE SOLVED: To correctly, precisely and easily adjust the toe angle in a short time. SOLUTION: The force generated when a wheel is rotated on a crawler is measured and operated, and the data of the primary differential value of the horizontal force is plotted along the time axis. The operation is implemented by shifting the direction of the crawler by a specified angle from the reference position, the data on the right side is compared with the data on the left side, the combination of the waveform to balance a left rear wheel with a light rear wheel is found, and the high straight stability is obtained by changing the toe angle of each wheel by the angle from the reference position in the circulating direction of the crawler whose waveform is obtained. The work is simplified because the toe angle can be adjusted in a single operation.  An intermediate part of a wire 424 locked to a support frame 148 provided with the crawler is wound around a pulley 416 of a rotary encoder 414, the rotational angle of the support frame 148 is enlarged and transmitted to the rotary encoder 414, and the small angle can be measured precisely.

Abstract: PURPOSE:To align the optical axis of optical parts and the optical axis of a connected optical fiber by subjecting the connected optical fiber to the specific motion to rotate around its central axis. CONSTITUTION:A movable base 16 facing a semiconductor laser module 18 consists of a Z axis moving part 24 which moves in a Z axis direction along a guide rail 22 provided on a bed 12 and X, Y axis moving parts 26, 28. One end of the optically connected optical fiber 34 is fitted into a groove 32 extending in the Z axis direction of a holding part 30 and the other end is connected to a photodetecting section.
