An information processing device for managing a vehicle including a toilet unit, a tank unit connected to the toilet unit for storing waste that flows from the toilet unit, and a traveling unit capable of moving the toilet unit and the tank unit. The information processing device performs control for disconnecting the traveling unit from the toilet unit and the tank unit when installing a toilet. The information processing device includes a control unit configured to acquire a storage amount of waste in the tank unit and to generate commands to the traveling unit to cause the traveling unit to replace the tank unit when the storage amount of waste becomes equal to or larger than a predetermined amount.

Information processing device, information processing method, and system

An information processing device includes a control unit configured to: acquire information on a destination of a user who uses a resting unit including equipment on which the user is able to sleep, information on an arrival time at the destination, and information on a place in which the user uses the resting unit; transmit a command to a traveling unit configured to be coupled to the resting unit and carry the resting unit such that the traveling unit is coupled to the resting unit and arrives at the destination at the arrival time; and transmit a command to a stimulation device configured to stimulate the user who is using the resting unit such that the stimulation device is activated before the traveling unit is coupled to the resting unit or before the traveling unit departs for the destination after being coupled to the resting unit.

An information processing device includes a controller. The controller is configured to generate, when information related to a request to use a cabin unit is acquired from a terminal of a first user who intends an activity in the cabin unit rather than traveling by the cabin unit, a command for causing a traveling unit to pick up the first user. The traveling unit is connected to and carrying a predetermined cabin unit associated with the activity of the first user. The controller is configured to generate, to the traveling unit connected to the predetermined cabin unit where a predetermined number of the first users or more is riding, a command for placing the predetermined cabin unit at a predetermined location.

A first metal powder is supplied to a substrate to form a beginning part of a clad layer. After the beginning part is formed, the second metal powder is supplied to the substrate. A concentration of at least one of Si, Ni, Mo, and Al in the first metal powder is lower than a concentration thereof in the second metal powder.

Method of producing clad layer and device for producing the same

An information processing device configured to control a traveling unit which is coupled to a resting unit including equipment on which a user takes a rest and carries the resting unit, the traveling unit being movable even while not coupled to the resting unit, the information processing device includes a control unit configured to: select a first parking lot in which the resting unit is to be arranged from among vacant parking lots within a predetermined area including a current position of a terminal owned by the user who desires to take the rest; transmit, to the terminal, information on movement from the current position of the terminal to the first parking lot; and transmit, to a first traveling unit, a command to carry a first resting unit to the first parking lot and arrange the first resting unit in the first parking lot.

A piston includes: a piston head; and a piston skirt connected to the piston head, wherein the piston skirt includes wall portions protruding outward from a surface of the piston skirt, the wall portions adjacent to each other in a circumferential direction of the piston skirt are inclined in directions opposite to each other with respect to a direction of movement of the piston in a bore for the piston, and define a tapered portion, and the tapered portions are spaced away from each other in the circumferential direction of the piston skirt.

A hardfacing alloy satisfies the following condition when the hardfacing alloy as a whole is 100 mass % (also simply referred to as '%,' hereinafter), Ni: 10-25%, Si: 1-3%, Fe: 3-18%, the total of one or more elements of Mo, W, and Nb: 6.5-20%, and the balance: Cu and impurities. In particular, it preferably satisfies Fe+2Mo&#x2265;22.6(%), Mo equivalent/Fe&#x2265;1.17, and Mo equivalent=Mo+0.522W+1.033Nb. In a hardfacing part composed of the hardfacing alloy, coarse hard particles are formed to ensure the wear resistance, and a soft phase present in the hard particles ensures the machinability. This may be understood as a raw material powder for hardfacing treatment and may also be understood as a hardfacing member in which a hardfacing part is formed on a base material using the raw material powder.

Hardfacing alloy and hardfacing member

A stainless steel that includes chromium and other alloying element as a plurality of alloying elements including: a base material layer including chromium of a specified chromium content necessary for forming a passive film or more; and a superficial layer including chromium at a lower chromium content than the chromium content contained in the base material layer, and the superficial layer including the other alloying elements at a same content of the other alloying element as the content of the other alloying element contained in the base material layer.
