Title: Method for applying photographic magnetic recording layer
Inventor: SAKAKIBARA YOSHIO
IPC: C09D7/12
Filed: 1992-06-08
Abstract: PURPOSE:To obtain a magnetic recording layer having an excellent coated surface state and the excellent stability of a coating liquid by specifying the viscosity of the coating liquid of the transparent magnetic recording layer to a specific value or below and specifying the specific surface area of the magnetic material to be used to a specific value or above. CONSTITUTION:The magnetic quantity and binder quantity of the transparent magnetic layer are required to be lowered in the case of impartation of this layer to the photographic sensitive material and the coating liquid of low-viscosity is required to be used in order to obtain the sample having good coated surface. The liquid viscosity is confined to <=120cPs, more preferably to <=40cPs, in order to impart the excellent coated surface form free from streaks and unequalness particularly in the case of the applying system using a wire bar. Even if the magnetic material is finely dispersed, the material begins to gradually settle in the coating liquid and supernatant is generated during long-term storage. Then, the dispersion stability of the magnetic liquid is improved if the specific surface area of the magnetic material to be used in the low-viscosity magnetic liquid is specified to >=40m<2>/g. The dispersion stability is further improved if the specific surface area is specified more preferably to >=47m<2>/g and further preferably to >=55m<2>/g.

Title: Cassette loading device
Inventor: ENDOU OSAMU
IPC: G11B15/675
Filed: 1981-09-17
Abstract: PURPOSE:To hold a cassette with high stability and assuredness at both the inserting position and the working position, by applying the desired elastic energy to the cassette in a cassette case via a roller. CONSTITUTION:When a cassette 2 is put into a cassette case 21, a roller 40 has the rotary movement with the cassette 2. Then the elastic force of a spring 44 is applied via the roller 40 to hold the cassette 2 with high stability and assuredness. Then the case 21 is shifted to the working position, and a lever 27 rocks, and the elastic force produced by the interlocking of a lever 38 and via the roller 40 is applied vertically to the cassette 2 regardless of the rocking of the lever 27. Thus the cassette 2 is pressed and held by support pins 51 and 52 with the even force and without causing any gap, etc. owing to the elastic force obtained by an up-down spring 31 and via the lever 27 and the roller 40. Accordingly the cassette 2 can be held with high stability and assuredness at both its inserting and working positions.

Title: Antenna directing device for artificial satellite
Inventor: KAWAKAMI YOUICHI
IPC: H01Q1/20
Filed: 1983-08-12
Abstract: PURPOSE:To improve the accuracy for directing the antenna with almost no friction by supporting elastically the antenna. CONSTITUTION:The requirements of the support of the antenna 1 are less resistance to the turning around X and Y axes and sufficient rigidity to other motions such as turning around the Z axis and linear displacement toward the X, Y and Z axes. Since a supporter 8 is formed with a neck at the middle part, the free turning around the X and Y axes and the sufficient rigidity toward the Z axis are attained by utilizing the deflection of the neck part. Furthermore, an elastic coupling 9 is provided to compensate the deficiency of the rigidity toward the X and Y axes and the turning around the Z axis. This is called a bellows, which is deformed freely to the turning around the X and Y axes and the displacement toward the Z axis but has sufficient rigidity to the turning around the Z axis and the displacement toward the X and Y axes.

CONSTITUTION:The starting material contg. boron and a starting material contg. iron is brought into a thermit reaction in the presence of Al powder to form high-Al ferroboron. This high-Al ferroboron is melted by heating, and Al in the molten ferroboron is oxidized by adding molten boron oxide to manufacture low- Al ferroboron. In this stage, refining slag contg. boric acid is produced as a by- product. The refining slag is used again as at least part of said starting material contg. boron for high-Al ferroboron. By this method, the yield of boron is increased, and low-C and low-Al ferroboron can be manufactured advantageously.

Filed: 1990-06-06
Abstract: PURPOSE:To easily decide the feature of a singular point in a diagram by describing the feature of the diagram based on phase relation between a projecting graphic with similarity over a certain value with the diagram. CONSTITUTION:The feature of the diagram is described based on the phase relation between the diagram and the projecting graphic with similarity over a certain value with the diagram, and it is checked to which part (end point, branch point) the projecting graphic corresponds, and the thinning of the diagram is performed based on the above check, Assuming that a circle is set as the projecting graphic for example, a disk of radius (r) centering around a black point at each black point comprising the diagram is considered. In such a case, the disk contains the neighborhood of the black point as increasing (r), and also, it contains partially a stroke to which the neighborhood belongs gradually. A metastable phase in the change of phase relation between the disk and the stroke is described, and a feature is found from the phase of a neighborhood system centering around the black point. In such a way, it is possible to obtain an appropriate graph even at a so-called singular point.

Title: Coating liquid for thermal transfer ribbon
Inventor: MOMOSE HIROO
IPC: B41M5/30
Filed: 1988-06-17
Abstract: PURPOSE:To improve an antistatic effect, and to continue the effect for a prolonged term by adding an antistatic agent composed of a surface-active agent into a coating liquid in an emulsion type with wax. CONSTITUTION:An antistatic agent consisting of a surface-active agent is added into a coating liquid for an under layer and/or a back layer in an emulsion type with wax. An agent made up of anion group and nonion group surface-active agents is preferable as the antistatic agent composed of the surface-active agent because it is held in emulsion in the type of stable wax emulsion. Ester wax, carnauba wax, etc. particularly have a polar group and the excellent stability of emulsion and are used preferably from the viewpoint of the durability of an effect and transfer characteristics as wax. A remarkable antistatic effect is recognized in the measurement of surface resistance using an ultra- insulation resistance tester or the measurement of the half life of the quantity of charge employing a charge-quantity measuring instrument in a thermal transfer ribbon with such under layer and/or back layer.

Title: Preparation of multi-layer film
Inventor: MURAKAMI YOSHINAGA
IPC: B32B37/00
Filed: 1985-07-08
Abstract: PURPOSE:To obtain an easily peelable no-dust film, by extruding a thermoplastic resin in molten state into at least three layers, by preventing the adhesion of the layers each other by blowing out a cooling gas between the layers except both side end parts, by laminating the resin layers on a casting roll and by adhering both side end parts on the melt. CONSTITUTION:A thermoplastic resin 2 supplied in an extruder 1 is extruded from a multi-slit die 3 into molten resin films 4 of at least three layers, which is cooled by a gas blown out from the gas-blowing holes or slits 8 of cooling gas pipes 7 set between the resin outlet slits 6 of the multi-slit die 3. This cooling operation prevents the adhesion of films by making the film temp. below the m.p. of the resin at laminating operation except the side end parts of the molten resin films. Jet air flow is blown onto the both ends of the films 4, which are then forcibly pressed and laminated by an air knife 12 on a casting roll 13. Both side end parts or each layer are adhered together and the multi- layer film 14 thus obtained is wound up. Upper and bottom layers are easily peelable by cutting the both side end parts of the film and the intermediate layer can be obtained as a dust-free film.
