IPC: G11B11/10
Filed: 1991-02-08
Abstract: PURPOSE:To make total thickness of recording film thin and to easily execute composition adjustment and film-forming by using an artificial grid film of Pt/Co or Pd/Co as an assistant layer in a two type magneto-optical recording medium having a recording layer and the assistant layer. CONSTITUTION:In the two layer type magneto-optical recording medium of an optical modulation type having the recording layer and the assistant layer, total thickness of the recording layer is made thinly and the two layer type magneto-optical recording medium having high sensitivity is obtained by using the artificial grid film of Pt/Co or Pd/Co as the assistant film.

Title: Fluid mixer
Inventor: AKAMA KAZUO
IPC: B01F13/10
Filed: 1980-02-14
Abstract: PURPOSE:To reduce a pressure loss by linking a throat of a Venturi type mixer to the discharge side of the other Venturi type mixer to combine. CONSTITUTION:When two or more Venturi type mixers are combined, a throat of one Venturi tube 13 is linked to the discharge side of the other Venturi tube 14 with a piping 10. In operation, when flowing into the throat of the Venturi tube 13 from the piping 10, a mixed fluid blows off to the throat of the Venturi tube 13 already having a some degree of positive static force. Thus, this can reduce possible pressure loss.

IPC: H05K7/20
Filed: 1997-01-13
Abstract: PROBLEM TO BE SOLVED: To provide a cooler for enhancing performance by improving cooling capability per unit area without increasing a predetermined volume of the cooler. SOLUTION: The cooler comprises a heat sink 2 having a plurality of flat plate-like fins 22 formed of a metal board 2 having a contact surface with a radiator of a heater 1 and metals fixed to the board 2 and disposed in a row state, thereby radiating heat of the heater 1 by forcibly supplying cooling air from one to the other between the fins 22. In this case, the fins 22 have fins 221 each having a shape continued and bent in a waveform state to a flow direction of the air, and flat plate-like fins 220 at both ends. The air is collided with the fins 221 to form turbulance, and hence heat transfer of the entire fan 22 to the air is improved to improve cooling as the cooler.

Title: Blood-coagulation inhibitor and blood drawing container housing the same
Inventor: TATSUMI NORIYUKI
IPC: A61L31/00
Filed: 1999-01-26
Abstract: PROBLEM TO BE SOLVED: To provide a blood-coagulation inhibitor which is applicable to blood examination for all of chemical items, biochemical items and hematological items, is versatile, is excellent in the effect of preventing blood coagulation and is stable and inexpensive by using the inorganic acid salts of magnesium as effective components. SOLUTION: This blood-coagulation inhibitor is formed of the inorganic acid salts of magnesium as effective components and is particularly effective for coagulation prevention of the blood drawn for blood examination. The inorganic acid salts of the magnesium include, for example, magnesium sulfate, magnesium ammonium sulfate, etc., and their hydrate salts, etc. While these inorganic acid salts may be used alone or in combination of >=2 kinds, the magnesium sulfate and its hydrate salt are more particularly preferable in terms of performance and price.  The mechanism of the blood-coagulation preventive effect is indefinite and is estimated that the calcium ions in the blood participating the formation of thrombin having an effect of respectively decomposing fibrinogen and converting the same to fibrin and the formation of the fibrin net by the crosslinking of the fibrin are substituted for magnesium ions.

Title: Microfilm reader/scanner
Inventor: MANABE NAOKI
IPC: G03B21/14
Filed: 1992-02-03
Abstract: PURPOSE:To prevent illumination unevenness from being varied when rotating a projected image by putting the illumination unevenness in point symmetry with respect to an optical axis on a focused image. CONSTITUTION:The filament W2 of a light source 11 is helically wound along an imaginary rectangle that can be formed on a plane perpendicular to the optical axis, and is of such size that the envelope P2 of the filament W2 encompasses a circle C. As the magnification varies the position of the pupil of this zoom lens 15 is moved and the diameter of the diaphragm is varied so that the illuminance and the distribution of illuminance at that time are not varied much by the variation in magnification; the diameter of the circle C is therefore varied according to the magnification of the zoom lens 15. The filament configuration of the light source 21 is approximately a square. The light source is thus combined with a glass flat plate G1 which serves as an illumination uneveness correction means with its condensor-lens side subjected to frosting, so that illumination unevenness of point symmetry with respect to the optical axis can be obtained.

After the degree of vacuum in a sputtering chamber is set at about 1X10<-6>Torr, gaseous Ar is introduced into the chamber to attain 1X10<-3>Torr degree of vacuum. A holder fixed with the substrate is thereafter rotated over the two targets and is subjected to simultaneous two-dimensional sputtering by a magnetron sputtering method, by which the laminated recording layers are formed. The decrease of coercive force at a high temp. is thereby expedited and the angle of Kerr rotation is increased simultaneously.

Abstract: PURPOSE:To reduce power consumption by controlling the actuation of a degauss coil when the position of a display device main body is changed so as to reduce the number of times of degaussing, thereby avoiding the production of noise sounds at the application of power of the display device. CONSTITUTION:Suppose that the position of a CRT is changed when a power switch (c) is first turned on while a current is supplied to a microcomputer 9, then the computer 9 activates a degauss coil power relay (a) as well as a set power relay (b) to degauss the CRT and power application to the degauss coil D is not implemented regardless of the ON of the switch (c). Then the CRT is not energized till it is discriminated that the position of the CRT is changed next. Thus, the production of noise sounds due to the vibration of a frame is avoided and the number of times of degaussing is reduced, then the power consumption is reduced.
