Title: Magneto-optical recording medium
Inventor: UCHINO KENICHI
IPC: G11B11/10
Filed: 1998-01-08
Abstract: PROBLEM TO BE SOLVED: To obtain a magneto-optical recording medium which enables overwriting and has high sensitivity and high C/N by specifying the relation of the Curie temp. and the coercive force at room temp. of a magneto-optical recording layer and a recording assistant layer successively formed on a substrate, and forming a heat sink layer of specified thickness on the recording assistant layer opposite to the substrate side. SOLUTION: This medium is produced on such a manner that the Curie temp. Tc1 , Tc2 and coercive force Hc1 , Hc2 at room temp. of the magnetic recording layer and the recording assistant layer, respectively, satisfy Tc1 <Tc2 and Hc1 >Hc2 . As for the recording layer, it is preferable that the layer has the Curie temp. between >=120 deg.C and <=200 deg.C and >=10kOe coercive force. For example, TbFe and TbFeCo can be used. As for the assistant layer, TbFeCo, DyFeCo, etc., can be used having high Curie temp. and small coercive force. The assistant layer is formed to >1.2 times as thick as the recording layer. A heat sink layer comprising Au, Al, etc., having higher thermal conductivity than that of the recording assistant layer is formed.

IPC: F02M51/06
Filed: 1998-01-08
Abstract: PROBLEM TO BE SOLVED: To eliminate the formation of a deposit by paying attention to the fact that NOx which becomes a cause of the formation of a deposit becomes negative ions in gasoline and minus-charging the other bonding components (C=C, C=O, metal M on a surface of a nozzle hole) which are to be essentially bonded to repel them mutually.

Title: High-permance tape drive mechanism adapted to write and read large packet of block conversion data between gaps between blocks
Inventor: KATO JEFF J
IPC: G11B20/10
Filed: 1989-01-09
Abstract: PURPOSE: To improve tape efficiency by connecting an interface to a tape packet assembler/disassembler so as to connect a packet assembly/disassembly means to a large capacity storage device. CONSTITUTION: At the time of writing data into a tape driving device 25, a tape command and data arrive at the interface 8 and some commands working to the operation of a tape are extracted to be directly sent to a microprocessor 11 controlling the operation of the tape packet assembler/disassembler(TPAD) 7 according to a program stored in a read only memory 12. Though a command is extracted from a data stream and encoded, it can not be sent to the tape driving device in its characteristic shape. When a packet is prepared by TPAD 7, a tape mark is recovered and suited status information is sent to host calculation environment 1. Thereby high performance for clearly writing and reading is obtained.

Filed: 1988-01-08
Abstract: PURPOSE:To prevent peeling of tungsten and mutual diffusion between aluminum and silicon caused by sintering, by depositing aluminum after selectively depositing tungsten by a selective CVD method, within the same reaction chamber without decreasing a temperature by the CVD method. CONSTITUTION:Tungsten 3 is deposited only in a contact hole by a selective CVD method using tungsten hexafluoride gas and hydrogen gas. The deposition is performed at 300 deg.C for example while pressure within a reaction chamber is held at about 50Pa. Subsequently, aluminum 4 is deposited all over the surface by the CVD method using tri-isobutyl-aluminum gas for example within the same reaction chamber without decreasing the temperature. In this manner, a stable process can be realized without causing peeling of the tungsten layer 3 or mutual diffusion between the aluminum layer 4 and a silicon substrate 1 by sintering.

Filed: 1991-01-16
Abstract: PURPOSE:To execute stable transfer by holding the data transfer velocity of each line in a common control means and executing arbitration by starting the allocation of the high priority order of a bus request from a serial/parallel data converting means in the order of the high transfer velocity. CONSTITUTION:When no transmitting data are held in serial/parallel data conversion parts 2-1-2-N, those parts turn bus request signal lines 3-1-3-N to logic '1' and execute bus requests. When the plural bus requests are simultaneously executed, based on the contents of a transfer velocity holding part 11, a bus request arbitration part 12 accepts the bus request at the highest data transfer velocity through the signal line 3-1, for example. Then, a bus acknowledge signal line 4-1 is turned to logic '1' and the permission of bus use is applied. The conversion part 2-1 transfers parallel data with a memory under DMA. Thus, under run/over run is hardly generated, stable data transfer is enabled and the data transfer velocity can be set with arbitrary combination.

Filed: 1996-01-11
Abstract: PROBLEM TO BE SOLVED: To form a linear laser beam capable of uniformly heating a surface to be worked by arranging side by side a cylindrical lens, a prism and a condenser lens and forming a linear beam. SOLUTION: This system is constituted so that the cylindrical lens 4, the condenser lens 5 and the prism 6 in sequence from an incident side that laser light is made incident are arranged side by side on the same optical axis so as to be in parallel to each other. The laser light is compressed in the direction of an X axis by the cylindrical lens 4 to become an elliptic shape, and is converged by being made incident on the condenser lens 5 to become the beam close to a linear shape. Then, by being made the elliptic beam incident on the prism 6, the beam is divided to become linear divided elliptic shapes, and the laser beam with these shapes irradiates on the surface to be worked 2a. Thus, the temp. rise of the process surface being an integrated value of irradiated energy becomes nearly linear with respect to the width direction of the laser beam.  Thus, the surface to be worked 2a is heated uniformly.

IPC: G02F1/11
Filed: 1983-01-14
Abstract: PURPOSE:To prevent lowering of extinction ratio due to carrier leak by making angle of planes between incident laser beam of a modulator and modulation laser beam larger than spread angle of the beam. CONSTITUTION:A plane made by an incident beam L at the time of first diffraction and its diffraction beam L1 and a plane made by an incident beam L2 at the time of second diffraction and its diffraction beam L2' makes an angle phi. The angle phi is made larger than spread angle of the beam. Specified relation holds between power of each beam, diffraction efficiency, permeability of reflection mirrors 5, 6 etc., and extinction ratio due to carrier leak increases compared with the primary diffraction beam L1 at the rate of second power. Lowering of extinction ratio due to causes other than carrier leak can be made sufficiently small by making angle between a plane made by beams L and L1 amd a plane made by beams L2 and L2' sufficiently greater than spread of the beam, and using a pin hole and slit properly.

Title: Laser beam machining head

IPC: B23K26/06
Filed: 1999-01-11
Abstract: PROBLEM TO BE SOLVED: To send the whole assist gas to a machining part at high flow speed and to conduct laser beam machining with effectively using the whole laser beam. SOLUTION: The assist gas Q supplied into an assist gas nozzle 16 is ejected from the opening part 16a of a nozzle tip toward the cutting part 2a of an object 2 to be cut. At this time, the opening diameter D of the opening part 16a is made roughly equal to a cutting width (w) and is smaller than a conventional opening diameter. Thus, an assist gas ejection speed is accelerated as well as the whole assist gas Q is sent into the cutting part 2a. Because the opening diameter is narrowed, the diameter of the inner circumferential face of the assist gas nozzle 16a is narrowed down, the narrowed down inner circumferential face is served as a reflection face 16a. The laser beam made incidence on the reflection face 16a is reflected and irradiated/converged toward the object 2. Thus, the whole laser beam 3 is contributed to machining.
