Abstract: A developing apparatus includes an electrostatic latent image bearer, a developing sleeve, a case, and an air filter. The case accommodates a two-component developer and the developing sleeve. The air filter is attached to the case. The air filter has a thickness of 2 to 20 mm and has a density gradient with a pressure loss of 2 to 40 Pa at a wind speed of 10 cm/s. The air filter forms an airflow sucked into the case from a gap between the developing sleeve and the case and forms an airflow discharged from the case through the air filter. The two-component developer accommodated in the case contains a magnetic particle a surface of which is coated with a resin layer. The resin layer contains at least one type of chargeable particle.

Abstract: An engine operating device of a working machine includes a control assembly installed in a body, an operating lever mounted on a handle, and an operating cable. The control assembly includes a base member, a stop switch secured to the base member, and a lever member supported by the base member. The operating cable includes a throttle wire, a stop wire, and a cable tube in which the throttle wire and the stop wire are fitted. As the operating lever is moved to an engine stop position, the lever member moves to a release position, causing an engine to stop.

Abstract: A method for purifying nanoparticles by which a large amount of nanoparticles can be obtained in a safe manner and in a short time as compared to a conventional method for purifying nanoparticles. A method for purifying nanoparticles by which nanoparticles are purified from a dispersion liquid in which nanoparticles are dispersed in a solvent A used in synthesis of the nanoparticles, the method including: a mixing step of mixing the dispersion liquid, a solvent B that is miscible with the solvent A, and a solvent C that forms two phases together with the solvent B; a concentrating step of concentrating the nanoparticles in a phase of the solvent C; a washing step of forming a third phase containing the nanoparticles in the phase of the solvent C; and a purifying step of extracting the third phase and removing the solvent C from the third phase.

Abstract: A drive assist system that includes a processor that is programmed to: acquire a scheduled travel route for guiding a vehicle to a destination location to provide guidance on the scheduled travel route; acquire an along-the-way route to be followed when the vehicle travels along the way; acquire an attention location that requires a determination as to whether or not to travel; specify, as a guide target intersection, an intersection which is positioned between the attention location that is present on the along-the-way route and the vehicle and to which a road that can be traveled on without reaching the attention location other than the attention location that is present on the along-the-way route is connected; and provide guidance on the guide target intersection when guidance on the scheduled travel route is not provided.

Abstract: Movement guidance systems, devices, methods, and programs set a guidance branch point on a guidance route. The systems, devices, methods, and programs acquire a position and a shape of the guidance branch point and a prior branch point, and determine whether the prior branch point is adjacent based on the acquired information. The prior branch point is adjacent when the prior branch point exists within a first predetermined distance from the guidance branch point and is connected with a road in a same direction as the guidance branch point. When it is determined that the prior branch point is adjacent, the systems, devices, methods, and programs complete verbal guidance for the guidance branch point at a timing at which the movable body is located at a guidance end point that is located a second predetermined distance before the prior branch point.

Abstract: Travel guidance systems, devices, methods, and programs set a route from a departure point toward destination and acquire a position of a movable body along the route. The guidance systems, devices, methods, and programs determine whether the movable body has arrived at the destination by acquiring a distance from an end of the set route to the destination. When the acquired distance is less than a predetermined distance, the determination is based on the end of the route. When the acquired distance is equal to or more than the predetermined distance and the destination is a specific point, the determination is based on the end of the route. When the acquired distance is equal to or more than the predetermined distance and the destination is a point that is not a specific point, the determination is based on a position of the destination.

Abstract: A tiller for cultivating soil has a power source and a tilling shaft mounted for undergoing rotation by a driving force supplied from the power source. The tilling shaft has a hollow outer shaft and an inner shaft extending through the outer shaft. The inner shaft has a variable rotating speed and/or direction of rotation relative to the outer shaft. A power transmission mechanism transmits a driving force from the power source to the tilling shaft. The power transmission mechanism has a first power transmission system for transmitting the driving force from the power source to the outer shaft and a second power transmission system transmitting the driving force from the power source to the inner shaft. The second power transmission system has a hydrostatic transmission comprised of a hydraulic pump and a hydraulic motor for effecting a stepless change of the rotating speed of the inner shaft as well as a selective change of its direction of rotation.
