A sleeve soldering device has a displacement sensor and a heat flux sensor. The displacement sensor detects a physical quantity related to a pressure from a heated sleeve heated by a heater onto an electric board when the heated sleeve presses the electric board. The displacement sensor detects a physical quantity related to a deformation amount of the electric board due to thermal energy from the heater. The heat flux sensor detects a physical quantity related to a heat transfer amount from the heater to the electric board when the heated sleeve is pressed to the electric board. A control part compares each of detection values obtained from the displacement sensor and the heat flux sensor with a respective judgment reference so as to detect whether each detection value satisfies the respective reference.

Sleeve soldering device and method of producing electronic device

A display panel has a resin substrate and a printed layer formed on at least a part of the resin substrate through inkjet printing. The printed layer is formed from cured products of UV-curable inks each containing UV-curable monomers which are polymerized and cured by UV irradiation, and the printed layer has at least two such cured products having different pencil hardness values.

An indicator panel is shaped by thermoforming an indicator panel. The indicator panel includes a resin substrate and an inkjet design film on the substrate. The design film is formed by printing a UV hardening ink in an inkjet printing, and hardening. A crack and a removal of the design film can be decreased such that the formed indicator panel can have a high-quality design.

Indicator panel and method of manufacturing the same

An indicator panel for an instrument includes a translucent resin substrate having a first face and a second face opposite to the first face, and a design film on the first face of the substrate. The design film includes a translucent portion through which a light from the second surface of the substrate is transmitted, and an opaque portion which does not transmit the light from the second face of the substrate. The design film is produced by jetting droplets of a UV hardening type colored ink to the first face of the substrate in an inkjet printing, and radiating ultraviolet rays for a time within one second from the jetting so as to harden a mass of the droplets, in which a volume of the droplets is equal to or less than 30 pl.

A display panel includes a transparent image recording sheet having electrophotographically formed thereon at least a background portion, wherein space factor of pinholes per unit area of the background portion is no greater than 1&#xd7;10%. A method of manufacturing the display panel is also disclosed. The background portion has a transparent optical density of 3.0 or greater and an image portion has a transparent optical density of 1.0 or less, and preferably 0.1 to 1. A toner used for electrophotographically forming the background portion and the image portion has a number average molecular weight of 1,000 to 6,000 and a weight average molecular weight of 30,000 to 150,000 as measured by gel permeation chromatography with respect to a portion of the toner dissolved in tetrahydrofuran, and has respective molecular weight distribution peaks in molecular weight ranges of 1000 to 10,000 and 100,000 to 1,500,000.
