  • Patent number: 6326989
    Abstract: A thermal transfer printer head for discharging ink by heating ink to transfer ink to a transfer member. A sub-wall is provided in a supply passage adjacent to a transfer portion to raise the liquid level of ink in the supply passage so as to prevent a breakpoint of ink in the supply passage. Thus, ink consumed in the transfer portion is spontaneously replenished to the transfer portion through the supply passage by a capillary phenomenon so that continuous supply of ink to the transfer portion is smoothly performed. The structure is formed such that ink in an excessively large quantity is not introduced into a portion above a heater provided for the transfer portion. As a result, even if the wettability of an ink holding structure formed above the heater is raised owning to adhesion of thermally degraded substances or the like, introduction of ink into the portion above the heater in a large quantity and rapid change in the quantity of transferred ink can be prevented.

  • Patent number: 6221961
    Abstract: A composition prepared by adding as the sliding properties improving agent a small amount of ethylene-&agr;-olefin random copolymer having polar groups to engineering plastics including polyacetal, ABS, and polyamide is suitable for the manufacture of gears, rotary shafts and bearings by way of exploiting its molding processibility including excellent mold release properties, and at the same time is capable of enhancing its friction/wear resistance. As the sliding properties improving agent, an oxidation-modified material produced from ethylene-&agr;-olefin random copolymer or a graft-modified material prepared by graft-copolymerizing an ethylenic unsaturated monomer having carboxylic acid group, hydroxyl group or the like with ethylene-&agr;-olefin random copolymer is particularly preferable.

  • Patent number: 6214779
    Abstract: The present invention is directed towards a lubricating oil comprising a random copolymer of an &agr;-olefin/aromatic vinyl compound, wherein the copolymer has a viscosity falling within a specific range and comprises ethylene, an aromatic vinyl compound, and optionally an &agr;-olefin. The lubricating oil possesses excellent viscosity properties, thermal stability, oxidation stability, abrasion resistance, and compatibility with lubricating oil additives. The random copolymer having a different viscosity range is useful as a viscosity index improver and a compatibilizing agent for a lubricating oil. The invention also provides a lubricating oil composition comprising a base oil and the viscosity index improver or the compatibilizing agent. The invention further provides a fuel oil composition comprising a fuel oil fluidity improver based on the above random copolymer having a different viscosity range and a middle fraction fuel oil having a boiling point of 150 to 400° C.

  • Patent number: 6120130
    Abstract: Disclosed are a recording method and a recording apparatus which are superior in transfer performance such as transfer sensitivity and transfer speed. When causing ink held in a transfer section to fly upon heating by a heater to be transferred onto a transfer target member placed opposite to the transfer section, a surface tension gradient and/or an interface tension gradient is developed in the surface of the ink under the heating, and the ink is forced to fly in the form of a mist by utilizing the Marangoni flow of the ink caused by the surface tension gradient and/or the interface tension gradient.

  • Patent number: 6099626
    Abstract: In a recording substance (ink 22) supplied to transfer to a body to be recorded on (printing paper 50) and effect prescribed recording on this body to be recorded on, the content of residual impurities which after the recording do not transfer to the body to be recorded on and remain is made less than 2wt %. As a result, the occurrence of residual impurities (residual solids) produced on the head during recording is prevented, the influences of such residual impurities are avoided and high quality recording with excellent sensitivity and tonal reproducibility is always obtained.
