Title: Fuel injection valve
Inventor: NARAHARA YOSHIHIRO
IPC: F02M47/00
Filed: 1997-04-01
Abstract: PROBLEM TO BE SOLVED: To set injection characteristics of fuel to be injected actually to predetermined boot type characteristics without reducing a displacement speed and an injection pressure of a needle valve element. SOLUTION: A displacement of a needle valve 86 in opening injection holes 84, 85 is stepwise changed with time (i.e., boot type characteristics), and the plurality of injection holes 84, 85 are opened in sequence. Consequently, an initial injection state is determined by the area of the first injection holes 84 and is hardly influenced by the displacement of the needle valve element 86, so that it is unnecessary to reduce a displacement speed of the needle valve element 86 and it is possible to increase an initial lift quantity. Furthermore, since the displacement of the needle valve element 86 is stepwise changed with time, like boot type characteristics, it is possible to secure a long holding time (a time when an initial injection ratio can be kept) without reducing the displacement speed of the needle valve element 86.

Title: Self-calibrating position transducer system, and its self-calibrating method
Inventor: MASRELIEZ KARL G
IPC: G01B21/02
Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To calibrate a position transducer using itself without requiring an external reference. SOLUTION: A transducer signal is sampled in plural positions arranged with equal intervals in respective scale waves, using a transducer 100 itself as a position reference. DC signal off-set, amplitude and nonorthogonality of fundamental, amplitude of a signal higher harmonic component, and a calibration value of position off-set are determined using a Fourier analysis tecnique. The transducer signal is corrected using the calibration value, and the calibration value stored at the last time is updated. Precision of this self-calibrating position transducer is enhanced using the stored calibration value.

Title: Manufacture of magnetic recording medium
Inventor: IWAOKA KAZUO
IPC: G11B5/85
Filed: 1982-05-17
Abstract: PURPOSE:To form a magnetic recording medium which has large thickness, high coercive force, and a high square ratio without decreasing a vapor-deposition speed, by providing vapor deposition sources at >=2 places, and forming a metallic thin film. CONSTITUTION:A high polymer substrate 3 from a payoff shaft 2 runs in contact with a cylinder drum 4 and is taken up by a take-up shaft 1. The vapor deposition sources 9 and 10 are placed on bases 7 and 8 installed under the cylinder drum 4 and used magnetic alloy materials consisting essentially of cobalt and nickel, and they are heated by heating source 11 and 12 to vaporize. Vapor atoms 13 and 14 from the vapor deposition sources 9 and 10 are made incident while their angles of incidence are limited by masks 5 and 6 for limiting the maximum angle of incidence to the high polymer substrate 3. At this time, the maximum angle theta1 of incidence is 90 deg., and the minimum angles of incidence are limited to theta2 and theta3 by the masks 5 and 6. Plural vapor deposition sources are used, so the film thickness of the metallic thin film is increased without decreasing the vapor deposition speed while the square ratio and coercive force are held high.

Title: Magneto-optical recording medium
Inventor: ASHIDA SUMIO
IPC: G11B11/10
Filed: 1991-04-16
Abstract: PURPOSE:To obtain the recording medium which allows high-speed overwriting by changing the intensity of a laser beam at a recording power level and an erasing power level, thereby allowing the formation and erasure of inversion magnetic domains. CONSTITUTION:This magneto-optical recording medium is formed of a magnetic layer 1, a nonmagnetic intermediate layer 3, a bias layer 2 and an antiinversion layer 4. The temp. of the layers 1, 2 rise to a Curie point or above and the temp. of the layer 1 is higher than the temp. of the layer 2 but attains nearly equal at the time of cooling if this medium is irradiated with the light beam of a recording power level PW. The Curie point of the layer 2 is set at the temp. of the layer 2 of this time. Then, the magnetization of the layer 2 is nearly annihilated and a leakage magnetic field H which is upward large is generated. The magnetization of the layer 1 is thus inverted and the recording magnetic domains are formed. On the other hand, the magnetic field H of the layer 2 is not generated and the erasing is executed by reversing the magnetization of the layer 1 at the time of irradiation with the erasing power level PE. The high-speed overwriting is possible in this way.
