摘要:
A flow meter for measuring a flow rate of a fluid passing through a fluid passage is provided with a throttle structure disposed at the inside, and it is connected to the fluid passage. The fluid passes through a groove via expanded grooves formed on a surface of a substrate which constitutes the throttle structure. The flow rate of the fluid passing through the fluid passage can be measured by detecting pressures and temperatures of said fluid on an inflow side and an outflow side concerning the throttle structure.

A surface processing method for processing the surface of an insulating article in which an ion-implanted surface-modified layer is effectively formed on the article 2. In surface processing the article 2 of an insulating material, an electrically conductive thin metal film 50 is first formed on the article surface. A pulsed voltage containing a positive pulsed voltage and a negative pulsed voltage is applied to the article in a plasma containing ions to be implanted to implant ions in the article surface. This implants ions at right angles to the article surface to generate a surface-modified layer 51. There is no possibility of the article 2 being charged up due to application of a pulsed voltage.

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.

A thermal transfer recording material for use in a recording apparatus in which said thermal transfer recording material is introduced into a transfer section having a porous structure by an effect of capillarity, subjected to a state transformation by heating, and then transferred to a recording medium disposed opposed to said transfer section, comprising:a dye having a melting point of 160.degree. C. or lower, selected from the group consisting of a dye represented by the general formula (I): ##STR1## wherein A.sup.1, R.sup.1 and R.sup.2 are as defined, and a dye represented by the general formula (II): ##STR2## wherein A.sup.2, R.sup.3 and R.sup.4 are as defined.

Plural LEDs 21 are mounted on a top surface 20a of a circuit board 20, and a circuit pattern 22 for supplying power to the LEDs 21 and metallic film islands 23 for heat radiation are provided on a back surface 20b. Further, lens 30 is provided on the top surface 20a of the circuit board 20, that is, a surface where the circuit pattern 22 and the metallic film islands 23 are not provided, so as to cover each of the LEDs 21. The lens 30 is cured after dripping a liquid resin including a silicone resin containing silica. Therefore, distortion of the cover members formed on the substrate by dripping the liquid resin is suppressed.

A thermal transfer recording material for use in a recording apparatus in which the thermal transfer recording material is introduced into a transfer section having a porous structure by an effect of capillarity, subjected to a state transformation by heating, and then transferred to a recording medium disposed in an opposed relation to the transfer section, comprising:a dye represented by the general formula (I): ##STR1## where R.sup.1 and R.sup.2 are individually a substituted or unsubstituted alkyl or alkenyl group, or a cycloalkyl group, and when both R.sup.1 and R.sup.2 are unsubstituted alkyl groups, at least one of R.sup.1 and R.sup.2 is a branched alkyl group.
摘要:
During the recording where a liquid dye 22 supplied through a dye passage 27 is supplied to a vaporizing means 17 due to the capillarity of many small columns 21 within a vessel formed by coupling of a glass base 14 and a Teflon protection plate 290, the liquid dye in the vaporizing means is vaporized by irradiation of the laser beam L and the vaporized dye is transmitted to a photographic paper 50 passing a vaporization hole (aperture) 23 for the purpose of recording. The protection plate 290 has a critical surface tension against the liquid dye which is smaller than a surface tension of the liquid dye. Since the critical surface tension of the protection plate 290 is set smaller than a surface tension of the liquid dye, wettability of the liquid dye against the internal wall surface of the vaporizing hole 23 is low and the liquid dye left unvaporized at the vaporizing hole 17 at the time of recording is never deposited on the internal wall surface of the vaporizing hole. Therefore, the vaporizing hole is always kept clear, transfer of the vaporized dye 32 to the photographic paper is never prevented due to deposition of dye to the vapotizing hole and thereby excellent recording quality can always be guaranteed.

摘要:
A recording unit structure comprising a recording material layer faced to a recording body with a space incorporated therebetween, so that said recording material is vaporized and transferred to said recording body through said space, provided that pores are provided to a vaporizing portion of the recording material in such a manner that the pores be present within the layer of the recording material. The recording unit structure of the present invention assures a recording of excellent quality, is made compact and light weight, yields a high thermal efficiency, and produces no used ink sheets and other wastes. The present invention also relates to a recording device comprising the same.
