Abstract: A method for producing a resin sintered body 1 by applying an ink 3 to thermoplastic resin powder 2 and sintering the powder, the method including the step of immersing an intermediate resin sintered body 1m, which has an unevenly colored region on the surface thereof and the whole of which has been already sintered, in a surface treatment liquid containing sulfuric acid and chromic anhydride, in which the concentration of chromic anhydride is 300 g/L or more, for 5 minutes or longer. When producing a resin sintered body by sintering thermoplastic resin powder, the surface of the resin sintered body can be evenly and sufficiently colored to an extent required without an unevenly colored region on the surface thereof, and also the surface of the resin sintered body can have a good appearance and smoothness.

Abstract: A printing device includes an image recording portion which records an image on a sheet, an image defect detection unit which detects the sheet on which image defects occur, a setting unit by which a sorting number of copies of the sheets is set, a first stamper unit which attaches ink to a leading end edge of the sheet on which the image defects occur, and a second stamper unit which is disposed so as to be arranged with the first stamper unit in a sheet width direction and attaches ink to the leading end edge of the sheet corresponding to the sorting number of copies.

Abstract: A reducing agent injection valve abnormality detection device for detecting clogging of a reducing agent injection valve in a reducing agent injection device has a pressure detection component that detects the pressure inside a supply path based on a sensor value of a pressure sensor, a pump control component that fixes the output of a pump in a state where the pressure inside the supply path has become a value in a predetermined range, a reducing agent injection valve control component that opens the valve for a predetermined amount of time in a state where the output of the pump has been fixed, and a clogging determination component that determines the extent of clogging of the reducing agent injection valve by comparing, with plural threshold values, the pressure, or a pressure drop quantity, inside the supply path when the valve has been opened for the predetermined amount of time.

Abstract: An image forming apparatus of an aspect of the present invention includes: a transport body that rotates while retaining a recording medium on an outer surface thereof; a liquid droplet ejection head that ejects liquid droplets onto the recording medium retained on the transport body; a collection unit, provided at a downstream side in a rotation direction of the transport body with respect to the liquid droplet ejection head and provided with a suction inlet through which a mist of the liquid droplets is sucked, that collects the mist sucked in from the suction inlet; and a guide member, provided between the suction inlet and the liquid droplet ejection head, that guides the mist toward the suction inlet.

Abstract: There are provided a reductant supply device and a control method for the reductant supply device, which can prevent heat damage of a reductant injection valve, and also prevent crystallization of urea solution due to excessive cooling of the solution reductant.

Abstract: A photosensitive material treating apparatus comprises a bulkhead provided between a plurality of treating tanks in which treating liquid is stored, and having an opening through which a photosensitive material is passed, an elastic blade which abuts against an opening wall of the opening to close the opening, arresting leakage of the treating liquid and, at the same time, which is elastically deformed to allow a photosensitive material to be passed, and a mounting member for mounting the elastic blade on a peripheral wall of the opening. The mounting member has a smaller linear expansion coefficient than that of the elastic blade, and is integrally formed with the elastic blade.

Abstract: A portable telephone apparatus 100 according to the present invention comprises a call waiting section and a telephone number acquisition section that can acquire telephone numbers of telephone apparatuses on the other end of lines. A telephone directory information registration section 109 registers telephone numbers associated with information on names. A caller confirmation section searches a telephone number of the telephone directory information registration section 109 based on the telephone number acquired by the telephone number acquisition section and confirms the caller. A character string speech conversion section converts the character information on the name of the confirmed caller to speech information. A caller information notification section notifies the user of the speech information from the character string speech conversion section when an incoming call arrives during a call with speech at a volume level which does not disturb the call.
