Title: Magnetic head
Inventor: MURAI MASAMI
IPC: G11B5/127
Filed: 1988-04-27
Abstract: PURPOSE:To remove a working deterioration layer, to prevent the ununiformity of an effective gap length or the generation of bubbles and to obtain high performance by providing a chrome layer in both sides of a magnetic gap, which is formed by sandwiching a ferromagnetic thin metallic film on the joining surface of a ferrite core half body pair. CONSTITUTION:A 'Sendust(R)' thin film 3, a chrome layer 4a and further SiO25, which goes to be the gap, are successively laminated on a ferrite core 1, which goes to be a tray ring side, by sputtering after reverse sputtering. A chrome layer 4b is formed on a ferrite core 2, which goes to be a reading side, as well by the sputtering after the reverse sputtering. Both ferrite half body pairs are welded by an abutting glass 6. Thus, for the effective gap length of a magnetic head, the working deterioration layer is removed and stabilized and diffusing reaction between 'Sendust(R)' and SiO2 is prevented. Then, the magnetic head of the high performance not to have magnetic degradation can be obtained.

Title: Image reader
Inventor: TAKAHASHI MARIKO
IPC: H04N1/04
Filed: 1996-04-25
Abstract: PROBLEM TO BE SOLVED: To prevent uneven illuminance of a light onto an original in the image reader. SOLUTION: A light guide member 7 to lead a light of a light source 10 provided to a side of the reader to an original is configured by arranging a plurality of light guide chips 8 side by side linearly in a main scanning direction of the reader (original read line direction). An adhered face 9 of each light guide chip 8 with respect to other light guide chip 8 is set so that the face 9 is intercepted to an optical axis of the incident light from the light source 10 (e.g. orthogonal or at an angle of 45 deg.). Part of the incident light from the light source 10 is reflected multiply in the inside of each light guide chip 8 and the reflected light is emitted in a line toward an original face from an emission face of the light guide member 7 with uniform illuminance independently of the distance from the light source 10.  Or a refractive index of a collecting optical member of the light guide member at the original side is selected higher than that at the opposite side. Through the constitution above, it is prevented that the illuminance is higher toward the light source side in the main scanning direction.

IPC: G02B27/22
Filed: 1984-05-24
Abstract: PURPOSE:To enable observation, i.e., distance measurement or stereoscopic vision by constituting an endoscope in such a manner that the optical axes of two approximately parallel optical systems for observation are movable in the directions opposite from each other with respect to an object to be observed in the radial direction of the top end of the endoscope and are prevented from exceeding the outside diameter at the top end of the endoscope in the retracted state of the optical systems for observation. CONSTITUTION:Moving members 11, 11' and intermediate members 12, 12' are held retracted and the top end 10 of the endoscope can be smoothly inserted into the body in the case of such insertion. The observation of the object to be observed is executed by selecting the space between the optical axes O, O' of the optical systems for observation at a suitable length L0 according to the distance from the object and moving the optical axes O, O' until the space L attains L0. The observation of the object to be observed, i.e., distance measurement or stereoscopic observation can be thereby executed adequately. The adequate base length is realized according to the distance from the object particularly when the end of the endoscope moved in proximity to the object and therefore the observation of said object, i.e., distance measurement or stereoscopic vision is adequately executed.

CONSTITUTION:A graphic output controller 13 is equipped with a means 15 which calculates the amounts of respective divided data and generates the seed control commands for the graphic output device 30 according to the amounts of data, a means 19 which stores the speed control command, a means 20 which sends out the speed control command stored in the storage means 19 to the graphic output device 30 according to the sent state of the raster data. Then the plotting speed of the graphic output device 13 is made fast for a part which is low in drawing density, i.e. short in the data processing time in the graphic output controller 13, but made slow for a part which is high in drawing density, i.e. long in the data processing time in the graphic output controller 13. Consequently, the operation time of the graphic output device 30 required for plotting is optimized and intermittent operation is precluded.

Title: Magnetic head and its production
IPC: G11B5/23
Filed: 1992-03-30
Abstract: PURPOSE:To provide the magnetic head of a low cost which can improve an overwriting characteristic without deteriorating the quality of reproduced signals and to provide the process for production thereof. CONSTITUTION:A magnetic circuit having an annular shape is constituted of a core 10 wound with a conductor coil 11 consisting of a metallic conductor and a small-width gap 12 parting a part of this core 10. This gap 12 is formed so as to have a prescribed angle of 45 to 75 deg. with a sliding surface 13 which operates to record and reproduce information to and from a magnetic recording medium and to incline to the rear side of the relative moving direction of the magnetic recording medium. The angle part dull to the front side in the relative moving direction of the magnetic recording medium arises near the gap 12 and likewire the angle part actuate to the rear side arises thereon. The front side is magnetically satd. by the magnetomotive force lower than the rear side and the recording magnetic field having the magnetic field intensity asymmetrical with the center of the gap 12 is formed. The overwriting characteristic is thus improved by the expansion of the recording area in the depth direction of the magnetic recording medium and the narrowing of the magnetization inversion width.

Title: Swirl fluidized-bed type heat exchanger
Inventor: KOMATSU SHIGERU
IPC: F28D13/00
Filed: 1978-08-29
Abstract: PURPOSE: To prevent the deposition of floating matter and to improve the waste heat recovery efficiency by providing the outer peripheral wall of a fluidized-bed device with a fluid inflow port at a point above a perforated plate in such a manner as to open its mouth in the tangential direction.  
     CONSTITUTION: The hot gas introduced from a hot waste gas introduction port 12 contains much floating matter. The powder already fluidized in vertical direction will swirl, aided by the air flow in tangential direction; the upper surface of a perforated plate 5 undergoes the circumferential cleaning action of the powder and is kept in polished state, which together with the action of the rising air flow passing through the plate 5 will prevent the clogging of the pores. A multi-coil heat  transmitting pipe is also protected from the deposition of the floating matter. Thus,  waste heat can be efficiently recovered from the hot gas entraining floating matter,  and energy can be saved.

Abstract: PURPOSE: To provide a wire bonder and a bonding method in which the wire bonding can be carried out at high speed by driving a solid state image sensor and a bonding head individually and reducing the mass at the movable part of an XY table mounting the solid state image sensor. CONSTITUTION: Independently from a first XY table for mounting a bonding head 51, a second XY table 72 for mounting a solid state image sensor 62 is disposed oppositely to a frame for holding a lead frame. Since the second XY table 72 is disposed oppositely to the frame for holding a lead frame and simply required to hold the solid state image sensor 62, mass can be reduced at the movable part of the second XY table 72. Consequently, response of the second XY table 72 can be enhanced resulting in a bonder having short tact time.

Abstract: PROBLEM TO BE SOLVED: To prevent an alignment mark for vanishing by selectively making a metal film on an alignment mark thinner than the other part or removing it in a polishing process which has a polishing surface smaller than the area of a substrate. SOLUTION: A substrate is set on a chemical-mechanical polishing device(CMP device), to polish the entire surface of a metal film 4 on an alignment mark 2.
