Title: Forming method of photomagnetic recording medium
Inventor: FUCHIGAMI YASUKO
IPC: H01F41/18
Filed: 1991-02-15
Abstract: PURPOSE:To increase coercive force, by a method wherein, when a recording film of photomagnetic recording medium having Pt/Co lamination structure is formed, it is formed under the condition that the film formation rate of Pt and that of Co are lower than or equal to 34Angstrom /min and 10Angstrom /min, respectively. CONSTITUTION:Co layers 2 and Pt layer 3 are repeatedly laminated in this order on a glass substrate 1. When a Pt/Co lamination film is formed on the substrate 1, a rotary shaft 8 is set as a rotation center, a substrate holder 9 is rotated, and a Co target 6 and a Pt target 7 are subjected to sputtering by a power supply 10 and a power supply 11, respectively. When the substrate 1 comes to a region facing the Co target 6 isolated by a partition 5, a Co layer is formed. When the substrate 1 comes to a region facing the Pt target 7, a Pt layer is formed. When these layers are formed under the condition that the film formation rate of Pt and that of Co are lower than or equal to 34Angstrom /min and 10Angstrom /min, respectively, the coercive force becomes higher than or equal to 700Oe. Thus the coercive force having a level capable of practical use can be obtained.

Inventor: SUWA HIDEYUKI
IPC: B65G17/12
Filed: 1984-02-09
Abstract: PURPOSE:To provide an apparatus for unloading granular powder from a hold and feeding same, which is reduced to a compact size and which can reduce power consumption and stably unload and feed granular powder by providing a feeder on the axis of a rotary drum mounted below a conveyer. CONSTITUTION:A conveyer 22 and a rotor 46 are driven to lower the lower end of the conveyer onto granular powder 14 in a hold 12. Thus, the granular powder 14 is forced to flow in an opened take-in port 50 of a feeder 30 by its gravity, and scraped up by a blade 34 to be carried by the conveyer 22. Subsequently, the take-in port 50 is lowered into the granular powder 14, and the feeder 30 is moved back and forth by a cylinder 62, so that granular powder on the front and rear surfaces are removed by a casing 44 to smooth scooping. In this arrangement, granular powder can be conveyed stably with a small-sized apparatus.

Title: Fuel controller of internal combustion engine
Inventor: HARA TOSHIRO
IPC: F02D41/22
Filed: 1988-02-01
Abstract: PURPOSE:To precisely control the quantity of fuel supplied by computing that quantity without using a factor of previous load data if it is low, the detected quantity of intake air is low and the difference between the previous load data and the actual output of an AN detecting means is great. CONSTITUTION:A result obtained by an AN detecting mean 20 which detects the detection output of the quantity of intake air from a Karman's voltex street quantity detector 10 on the basis of the specified crank angle sent from a crank angle sensor 17 is exhibited as an AN(t). When a deciding means 21 determines that the previous load data is low, the detection output for the quantity of intake air is low and there is a great difference between the previous load data and the actual output of the AN detecting means 20, the AN(t) is considered unreliable. When the AN operation means 22 calculates an AN(n), the factor of the AN(t) is excluded in this calculation and compensated using the signal of a water temperature sensor 19 before sent to an injector 14. Thus, during the transient period, the air-to-fuel ratio may be controlled properly.

IPC: H03H9/17
Filed: 1987-02-02
Abstract: PURPOSE:To improve spurious characteristic by forming a vibrating electrode made of a conductive coating film to both main surfaces of a piezoelectric substrate and applying conductive or insulation paste to at least one surface of the conductive coating film thereby reducing the parasitic vibration of the piezoelectric resonator itself.
