  • Publication number: 20220298370
    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.

  • Patent number: 10355580
    Abstract: A DC-DC converter includes a protection function for handling a reverse connection state, and a protection function for handling a predetermined abnormality other than a reverse connection state, while reducing conduction loss. The DC-DC converter includes a first protection circuit unit, and a switching element on a first conductive path of a high-voltage side switches to an OFF state upon a predetermined abnormal state being detected to prevent a current from flowing into a voltage conversion unit. Furthermore, a reverse connection protection circuit unit and a switching element, on a third conductive path between the voltage conversion unit and a reference conductive path, is configured to switch to an off state if at least a low-voltage side power supply unit is in a reverse connection state, preventing a current from the reference conductive path. Thus, a current is prevented from flowing toward a power supply that is improperly connected.

  • Patent number: 10344455
    Abstract: Operating information (a pilot pressure, a pump pressure, a hydraulic oil temperature, an engine rotational speed, an hour meter and the like) of a hydraulic excavator and use environment information (operator information) of the hydraulic excavator are transmitted to a center server together with body information (for example, a model, a type, a type number, an identification number and the like) from the hydraulic excavator. For example, when a hydraulic hose as a replaceable component of the hydraulic excavator is replaced, the replaceable component information (a replaceable component name and a replacement date) is transmitted to the center server from a computer for maintenance. The center server predicts a replacement time of the replaceable component (hydraulic hose) using the use environment information of the hydraulic excavator in addition to the operating information and the replaceable component information of the hydraulic excavator.

  • Publication number: 20170040968
    Abstract: Provided is a communication apparatus according to which the degree of balance between two electric wires on which a signal is sent can be increased. A communication apparatus transmits and receives a superposed signal via a control line and a ground line. In the communication apparatus, a common-mode noise filter removes common-mode noise from the superposed signal. A LPF extracts the charge control signal from the superposed signal from which the common-mode noise is removed, and outputs the extracted charge control signal to a charge control apparatus. The BPF extracts a communication signal from the superposed signal from which the common-mode noise is removed, and outputs the extracted communication signal to a communication unit via a protective circuit and a conversion circuit.

  • Publication number: 20160005819
    Abstract: Contact resistance between a SiC substrate and an electrode is decreased. When a silicide layer is analyzed by Auger Electron Spectroscopy (AES) sputter in a direction from a titanium layer side to a SiC substrate side, sputtering time corresponding to a depth profile of the silicide layer is defined as ts. In this case, a depth profile of the silicide layer from the titanium layer side in a range of sputtering time from 0.4ts to ts contains a region where titanium atoms determined by the AES sputter accounts for 5 at % or more of all atoms determined by the AES sputter.
