Title: Electroconductive paste and its manufacture
Inventor: TSUJIKU KOICHIRO
IPC: H01G4/12
Filed: 1990-11-27
Abstract: PURPOSE:To eliminate sheet attack to a green sheet by dispersing an organic binder containing metal powder colloidally in the water. CONSTITUTION:An organic binder containing metal powder is dispersed colloidally in the water to form an electroconductive paste. Any sort of metal powder which provides electric conduction, may be used, for example powder of Ag, Pd, etc. Any sort of organic binder which forms a colloidal dispersion in the water, may be used, for example vegetable oil, fat, etc. When this electroconductive paste is attached by printing onto a green sheet, the solvent for the organic binder containing metal powder does not act on the organic binder of the green sheet. Thus the green sheet is prevented from sheet attack.

Inventor: YOSHIMOTO SHIGETAKA
IPC: F16C17/02
Filed: 1991-11-15
Abstract: PURPOSE:To maintain the bearing rigidity while decreasing the windage loss of a rotary polygon mirror or rotary single-surface mirror in its rotation by sucking air at the outer periphery of a motor rotation part through a hole constituting a dynamic pressure bearing part when the motor rotation part rotates to lower the atmospheric pressure in the optical deflector. CONSTITUTION:A dynamic pressure shaft 1 and a cover member 4 are fixed through an O ring 20 and the cover member 4 and a motor case 3 are fixed through an O ring 21 without any gap. The space in the motor rotation part and the outside are linked to each other through a lengthwise hole (g) formed in the dynamic pressure shaft 1 through the gap between the dynamic pressure shaft 1 and a sleeve 2 and holes (b) and (c) communicating with the hole (g). When a motor part consisting of a yoke 16, a coil 15, a Hall element 18, and a magnet 22 is driven, the sleeve 2 fixed to the magnet 22 rotates and the rotary polygon mirror 5 fixed to a hub 6, fixed to the sleeve 2, with a screw 9 further rotates.

Title: Water level gauge
Inventor: UMEZAWA SOHEI
IPC: G01F23/00
Filed: 1988-12-23
Abstract: PURPOSE:To enable adaptation to a large displacement of a liquid surface with a higher durability by supporting a displacer partially submerged in a liquid to be measured with a load detector of a load cell to eliminate a moving part. CONSTITUTION:A cylindrical displacer 17 with a lower end closed and an upper end opened is inserted into a wave breaking pipe 15 and so arranged that a section thereof parallel with a liquid surface 18 of a liquid 16 to be measured flushes at vertical points. Then, a load detector 20 comprising a load cell is arranged between a flange part 19 and a sole plate 11 of the displacer 17 and the displacer 17 is supported therewith. With such an arrangement, as a load of the displacer 17 decreases proportionally with a rise in a liquid level, a displacement value of the liquid level can be detected as variation value of a load of the load detector 20. This eliminates a mobile element, thereby achieving a higher mechanical durability.

Title: Negative charge carrier for electrostatic charge image developing
Inventor: ASANAE MASUMI
IPC: G03G9/113
Filed: 1992-11-13
Abstract: PURPOSE:To lower the resistance of a resin coat carrier which is a negative charge carrier for positive charge toner and to improve image quality due to sufficient effect of a developing electrode from a sleeve by adding conductive particulates having the pH value higher than a specific value to the surface of a resin, with which the surf ace of a magnetic material core is applied, and by keeping the volume resistivity at a specific value or less. CONSTITUTION:The surface of the magnetic material core is applied with the resin and the conductive particulates of >=pH7.5 are added on the surface of the resin to keep the volume resistivity at <=10<5>pH.Cm. The carrier durability and static chargeability are stabilized because the surface of the magnetic material core is applied with the resin in such a manner. Further, the quantity of negative electrostatic charge on the surface of the resin can be increased because the conductive particulates being >=#7.5 are added on the surface of the resin of the resin coat carrier. Further, the electric resistance of the carrier is reduced due to the electrical conductivity of carbon black dispersedly stuck or fixed approximately uniformly to the surface of the carrier. As a result, sticking of the toner to a latent image part is stably executed due to the electrode effect of the sleeve holding the developer.

IPC: A61B8/14
Filed: 1990-11-28
Abstract: PURPOSE:To obtain an exact and clear image even at the point where sound rays do not intersect with a reflector but intersect therewith in a size range by preventing the sound rays from intersecting with the high-accuracy part of a B mode image and prohibiting the phase correction in the range where the neighboring part exists at the distance under prescribed value with the high-accuracy part. CONSTITUTION:A phase correction controller 8 evaluates the phase obtainable from the output signal of a wave receiving beam former 3b in accordance with the phase error data stored in a phase error distribution memory 10 and inputs a corrected value to a wave transmitting beam former 3a and the wave receiving beam former 3b to make phase correction. A correction processing and deciding section 11 reads out the previously stored image data from an image memory 6. If this section decides that the respective sound rays do not intersect with the high-accuracy part H on the B mode image but have the parts intersecting with a magnified part h, the section outputs a control signal to prohibit the phase correction in this intersected part of such sound ray to a phase correction controller 8. The image data which is not subjected to the phase correction in the intersected part is obtd. and the clear image free from distortions and blurrs is obtd.

Title: Foaming and molding of thermoplastic resin
Inventor: SUZUKI HARUO
IPC: C08J9/32
Filed: 1996-11-22
Abstract: PROBLEM TO BE SOLVED: To obtain a uniformly and minutely foamed molded product having a beautiful surface by mixing a thermoplastic resin raw material with thermally expandable microcapsules, kneading and melting the mixture to expand the microcapsules, and subsequently molding the expanded mixture. SOLUTION: This method for foaming and molding a thermoplastic resin comprises simultaneously charging a thermoplastic raw material and thermally expandable microcapsules into a hopper, mixing the materials, and subsequently foaming and molding the mixture in a die or a mold by the use of an extruder or an injection molding machine. When the thermoplastic resin of raw material is thermally melted in the extrusion or injection molding process, the synthetic resin outer shells of the thermally expandable microcapsules are softened, and a liquid or gas charged in the microcapsules is thermally expanded. Thus, the outershells of the microcapsules are expanded to form the foamed state. The method enables to select the sizes of the thermally expandable microcapsules, mix the selected microcapsules, control the foaming state, and thereby easily obtain an objective specific gravity.
