Abstract: PURPOSE:To perform rational formation of the coil in manufacturing a cylindrical coil for motors, by selecting a circle having a radius r so that its center is located at the position where an angle theta is formed with bending lines; when determining the diameter, the length, and the number of layers governing the number of conductors and air gaps with respect to the cylinder to be formed. CONSTITUTION:When the bending is performed to form four equally divided portions in the circumferential direction of a ring-shaped disc coil 1 with an outer diameter of 2R, is selected a circle, wherein a radius is r and the extended portions of two perpendicular diameters form the angle theta=45 deg. with bending lines 2 and 3 (in general theta=360 deg./2n, where n is a number for equal division). In this case, the outer diameter 2R and the radius r are selected so that the diameter D of the cylindrical coil satisfies D=4r/pi, and the length L of the cylinder satisfies L=(2R<2>-r<2>)<1/2>. Thus, the outer diameter and the bending positions are determined, conductor portions 4 are formed as shown in the Figure, thereby the cylindrical coil is formed.

IPC: G11B5/53
Filed: 1991-03-14
Abstract: PURPOSE:To shorten the response time required to switch the track width in the magnetic recording and reproduction device used by switching the track width of one magnetic head core. CONSTITUTION:The magnetic head core 1 forming the track width by laminating magnetic materials being different at the Curie temp., is fixed at a rotary drum 9. In the case that it is operated by narrowing the track width, a laser drive circuit 7 is made ON and heat beams from a laser light source 6 being fixed on the outside of a rotary drum 9 are ejected, and irradiate the surface of the magnetic head core by converging those with an optical system 8. Hence the temp. of the magnetic head core raises in a moment and the lower part at the Curie temp. of the laminated structure becomes nonmagnetic and the effective track 1 width becomes narrow.

Title: Core material for artificial plant
Inventor: TOMINAGA KAZUO
IPC: A41G1/00
Filed: 1993-02-16
Abstract: PURPOSE:To provide the structure of the core material for ornamental artificial plants mimicking natural grass or trees. CONSTITUTION:An artificial plant is so constituted as to be of tapered shape from the origin 2 toward the tip 3 with its core material 1 consisting of a restorable elastic material. This artificial plant, after shaped, restores its shape even if subjected to unnecessary external force, instead of being left deformed due to such external force as the case for conventional artificial plants. Therefore, even if the artificial plants of the present invention are arbitrarily packed in their shipment or transportation, they restore the shape on being unpacked; thus being needless of correcting the shapes at receivers for delivered goods, becoming highly easy to handle. Besides, because of having the above-mentioned design, this artificial plant can naturally give rise to such elegant appearance as to sway in the wind.

Title: Convergence device
Inventor: OGATA MASAO
IPC: H01J29/54
Filed: 1985-03-13
Abstract: PURPOSE:To prevent a color deviation from being caused by a temperature rise, by providing four-pole, six-pole and two-pole metal-containing composite magnets for a convergence device for an inline color cathode-ray tube. CONSTITUTION:A convergence device 5 for an inline color cathode-ray tube is made of four-pole and six-pole static magnets 6a, 6b, 7a, 7b and two-pole purity magnets 8a, 8b which are mounted on the neck of the tube so that the magnets can be turned for adjustment. The magnets are metal-containing composite magnets such as Alnico, which are not made of barium ferrite and whose absolute value of temperature coefficient is 0.05%/ deg.C or less. The temperature coefficient of each of the magnets is thus reduced to greatly diminish a color deviation resulting from a temperature rise when electron beams emitted from three electron guns are caused to converge on a point on a faceplate.
