Title: Element wire for use in insulated wire for outdoor wiring and electric wire
Inventor: KONO TSUKASA
IPC: H01B5/08
Filed: 1997-08-04
Abstract: PROBLEM TO BE SOLVED: To enhance corrosion resistance by forming unevenness on a surface of an element wire for use in an insulated wire for outdoor wiring and by causing a preservative to remain sufficiently in the uneven parts. SOLUTION: Longitudinally extending unevenness 1 is formed on a surface of an element wire, so as to form a sine curve in the circumferential direction. Such formation causes a preservative spread on the surface of the element wire to stay in the unevenness and to remain easily on the surface of the element wire, and therefore preservative effect is acquired adequately and corrosion resistance is enhanced. It is preferably from the viewpoint of the preservative holding effect to form the unevenness 1 over the whole circumference of the element wire. Shape of the unevenness 1 is need not be angular but has only to be smooth. Concentration of electric field on surface projections at protruding parts can be thereby suppressed.  The diameter of a circle formed by a center line of the uneven part are equal to the wire diameter of a conventional round wire and the sectional area of a cross-section normal to the longitudinal direction are set equal to that in the conventional case, an allowable current sufficient as an electric wire can be obtained.

Title: Thermal transfer ink
Inventor: TSUKAHARA MICHIYA
IPC: C09D11/037
Filed: 1985-09-24
Abstract: PURPOSE:To enhance the cohesive force of an ink in a molten state and enable clear images to be printed even in transfer to a paper having low smoothness, by incorporating a thermoplastic organic substance, a coloring agent and anhydrous silica in a thermal transfer ink, the organic substance being a wax or a mixture thereof with a thermoplastic resin. CONSTITUTION:A thermal transfer ink comprises a thermoplastic organic substance, a coloring agent and anhydrous silica. A wax or a mixture thereof with a thermoplastic resin is used as the organic substance. The wax shows a rapid lowering in viscosity on melting, and it has little cohesive force in the molten state. On the other hand, anhydrous silica in the wax in the molten state has a three-dimensional network structure of particles connected in the form of chains, thereby increasing viscosity and cohesive force. When an external force is applied, the viscosity is momentarily lowered, leading to higher transferrability, and when the external force is removed, the viscosity is again raised, thereby increasing the cohesive force after transfer. Since the transfer efficiency of the ink is enhanced by the series of effects, clear printing can be performed even on a paper having low smoothness.

Title: Ink jet printer
Inventor: MATSUMOTO HIROZO
IPC: B41J2/18
Filed: 1990-08-08
Abstract: PURPOSE:To prevent a nozzle from clogging to improve a printing quality by a method wherein a recording head is moved to a position opposed to a suction device by a controller based on an earlier time between a time elapsing a predetermined time from an initial time and a time upon completion of printing of a predetermined amount of data, and a nozzle clog is removed by the suction device. CONSTITUTION:A clog removing action is performed based on an earlier time between a time T2 elapsing a predetermined time (t) from an initial time and a time T1 at the end of a time (a) required for printing a predetermined amount of data. In this case, the action is based on the time T1. Namely, after a recording head 4 is moved to a position opposed to a suction device 11, a nozzle clog is removed by the suction device 11. A time required for this movement and clog removal is ignorably short in comparison with the times (t), (a). Therefore, the start and end times of the movement and clog removal action are assumed to be the same. The movement and clog removal action is repeated based on the end time T1 as a new initial time.

Title: Controlling method for servo track writer
Inventor: FUKUSHI MASANORI
IPC: G11B21/10
Filed: 1981-12-28
Abstract: PURPOSE:To obtain a controlling method capable of driving a motor in an  invariably constant speed rotation, by increasing the tensile strength of a belt  during the actuation of a motor and decreasing it during the constant speed  rotation of the motor. CONSTITUTION:When the motor is actuated, enough tensile force to prevent the belt from slipping at the contacting part between pulleys 2 and 6 is applied to the belt 3 in its inward direction by a tension arm 7 and a tension roll 8 and when the rotating spindle 5 of a magnetic disk 4 also enters into a constant- speed rotation state through the constant-speed rotation of the motor 1, the tensile force is reduced. Through the reduction of the tensile force, a slip of the belt 3 at the contacting part with the pulley 2 or 6 is permitted when the rotational fequency Tm of the motor per unit time varies owing to unevenness of the rotation of the motor and is small corresponding to the rotational frequency Td of the rotating spindle 5 of the magnetic disk 4 per unit time, and eliminated when the rotational frequency Tm corresponds to the rotational frequency Td.
