Abstract: PURPOSE:To produce a catalyst exhibiting high activity and large particle size, free of fine particles, having a high bulk specific gravity and capable of producing a poly-alpha-olefin with a high productivity by bringing an aluminoxane into contact with an inorganic oxide and bringing a transition metal, water, etc., into contact therewith. CONSTITUTION:This method is for producing a solid catalyst by hydrolyzing a trialkylaluminum with water, bringing the resultant aluminoxane of formula I or II (R is a 1 to 4C hydrocarbon residue; n is 1 to 50) into contact with a hydrous or anhydrous inorganic oxide and further bringing the obtained solid catalyst into contact with a transition metal compound represented by formula III or IV (A and B are each a univalent or divalent unsaturated hydrocarbon residue, etc.; R is, e.g. a straight chain saturated hydrocarbon residue containing a divalent nitrogen, etc.; M is a metal belonging to 4 or 5 group in the periodic table; X is, e.g. a halogen bonded to M). In this invented method, a transition metal compound is brought into contact with a solid catalyst component prepared by bringing an aluminoxane into contact with an inorganic oxide and water or oxygen is subsequently brought into contact therewith.

Title: Image forming device for wet developing
Inventor: KUROTORI TSUNEO
IPC: G03G21/10
Filed: 1989-09-22
Abstract: PURPOSE:To eliminate a stain due to a developer preventing the developer dipping from the lowermost part surface hitting the aperture of an air knife injection slit by locating at a downstream side from the lowermost part surface of an electric charge holding medium along the moving direction of the electric charge holding medium. CONSTITUTION:The developer dipping from the surface of the electric charge holding medium 21 is collected and dips downward to the lowermost part surface of the electric charge holding medium 21 between the squeezing means 65 of a wet developing means 60 and a transfer means 25. When the developer gets the air knife injection slit 91 wet and toner is fixed on the aperture part or inside of the slit 91, the elimination of an excessive solution is performed insufficiently due to the turbulence of an air knife current. Therefore, the aperture of the air knife injection slit 91 is located at the downstream side from the lowermost part surface of the electric charge holding medium 21 along the moving direction of the electric charge holding medium 21. Thereby, the developer dipping from the lowermost part surface can be prevented hitting the aperture of the slit, which prevents the stain due to the developer occurring.

Title: Magnetic head
Inventor: ORIHARA HIDEJI
IPC: G11B5/31
Filed: 1985-11-06
Abstract: PURPOSE:To simplify the structure by adopting the constitution that a boosting transformer is mounted on a base of a thin film magnetic head. CONSTITUTION:In a magnetic head 1 provided with a magnetic head 2 and a transformer 3, the transformer 3 comprising a yoke 9 and a magnetic base 4 uses a coil 6a formed by a lead wire 6 as a primary coil and a coil 10 wound on the yoke 9 as a secondary coil, the coils form a boosting transformer. Even when the magnetic head 2 is a one-turn magnetic head, a large output of a recording/reproducing signal is obtained by increasing number of turns of the secondary coil 10. Since the coil 10 at the secondary side is wound on the yoke 9, the winding position and the number of turns are selected comparatively freely and a suitable number of windings to realize a desired recording/re producing output is selected.

Title: Reflection type liquid crystal display device
Inventor: OODOI YUUZOU
IPC: G02F1/13357
Filed: 1998-09-01
Abstract: PROBLEM TO BE SOLVED: To make constitution simpler and brighter than heretofore and to enable the device usable even in a dark place by providing the device with a polarizing plate and a backward scattering polarizing plate which is transparent to the polarization component in one direction of light and scatters and reflects the polarization component in a direction perpendicular to this one direction to a direction reverse from the progression direction of the light. SOLUTION: The P polarized light transmitted through the polarizing plate 1 is converted to the S polarized light during the transmission through liquid crystal 3 of 90 deg. twist when the impression voltage to the liquid crystals 3 is off. This S polarized light is scattered and reflected backward by the next backward scattering polarizing plate 7. The S polarized light scattered and reflected backward by the backward scattering polarizing plate 7 is again returned to the P polarized light by the liquid crystals 3 and is transmitted through the polarizing plate 1. Since this light arrives at an observer, the display appears white.  In the state that the impression voltage on the liquid crystals 3 is on, the 90 deg. twist of the liquid crystals 3 is released and, therefore, the incident P polarized light on the liquid crystals 3 transmits the liquid crystals 3 in the state of the P polarized light, transmits the backward scattering polarizing plate 7 and is absorbed by a light absorption plate 8. Then, the light does not arrive at the observer and, therefore, the display appears black.

Abstract: PURPOSE:To allow air to flow smoothly to reduce the loss of air through a passage in an electric blower by incorporating a motor, an impeller, and an air guide, installing a casing which has an intake in the middle, and providing the blades of an impeller with members protruding to a passage at the outer peripheral end opposite to the rotational direction. CONSTITUTION:A casing 21 having a suction port 21a in the middle has an impeller 23 and an air guide 24 disposed inside and contacts with the motor frame of a motor 25 on the opposite side of the suction port 21a. In addition, the impeller 23 is formed of a plurality of blades 23a and front and rear face shrouds 23b, 23c. Further, the air guide 24 is used to introduce a fast air flow discharged from the impeller 23 into the suction port 25b of the motor 25. The blade 23a is provided with a member whose outer peripheral end face opposite to the rotational direction of the blade 23a protrudes to the inside of a passage and which has R in the opposite direction of R of the blade 23a. This constitution prevents ununiformity of air flow due to its drawing to one side of the impeller 23 to reduce the loss of air flow through the passage.

Filed: 1996-09-19
Abstract: PROBLEM TO BE SOLVED: To determine the progress of magnetization correction process, turning state of a vehicle or single turn of the vehicle at a glance by determining the azimuth of the vehicle based on the output from an azimuth sensor and a correction value from a correction value output means. SOLUTION: When magnetization correction is performed, an automobile is moved to a place as wide possible so that the automobile is insusceptible to the ambient field. When a magnetization correction switch S is depressed, indication flags corresponding to light emitting diodes 1D-16D are cleared entirely and the light emitting diodes 1D-16D are lighted entirely. When the automobile is turned, an azimuth sensor 11 detects geomagnetism and outputs a voltage corresponding to the geomagnetism. A correction processing means 22 determines a correction value based on the output voltage from the azimuth sensor 11. An azimuth operating means 23 operates the azimuth of the automobile based on the output voltage from the azimuth sensor 11 and corrects the azimuth with the correction value thus determining the angle of advancing direction of the automobile.  A decision is made whether the magnetization correction process has ended or not based by deciding whether all light emitting diodes are lighted or not.
