Polyalkyl(meth)acrylate based polymers which include straight chained Calkyl(meth)acrylates and have an average carbon number of 7.0 to 7.5 and a weight-average molecular weight of 300,000 g/mol or greater are a useful component for a lubricant composition. Furthermore, lubricant compositions containing such polymers show improved high temperature-high shear performance, especially in engine oil (EO) compositions.

Viscosity index improvers

The invention relates to a poly alkyl(meth)acrylate polymer comprising polybutadiene-based monomer units and a process for preparing the same. The invention also relates to the use of said polymer as a viscosity index improver in lubricant formulation and to lubricant compositions comprising said polymer.

Viscosity index improver and lubricant compositions thereof

An additive composition contains a viscosity index improver and a pour point depressant. A process can be used for preparing the additive composition. The additive composition can be used as a lubricant additive in a lubricating oil formulation, and lubricating oil formulations can contain the additive composition.

A service providing system includes one or more robots and an information processing apparatus communicably connected to the robots. The information processing apparatus acquires analysis information based on information in an area in which the robot provides a service, acquires robot state information from the robot, stores service information as information on the service, acquires one or more service triggers based on the analysis information, calculates a service effect based on at least any one of service information of a service corresponding to each of a plurality of service triggers, the robot state information, and the information acquired in the service providing area, the service effect being an effect of the service corresponding to each of a plurality of service triggers, selects a service trigger depending on the service effect, and causes the robot as a service execution subject to execute a service corresponding to the selected service trigger.

Service providing system, information processing apparatus, and method of controlling service providing system

An objective of the present invention is to promote efficiency improvement of a business by a mobile device. A business analysis server that analyzes a business in a mobile device system conducting the business by controlling a mobile device on the basis of a scenario includes a control unit, and a storage unit including a business index value database that manages a business index value indicating an effect of the business and a business index value history database that manages a change in the business index value as time-series data. The control unit receives scenario execution information when a business index value is designated, analyzes a correlation between the business index value and the scenario by referring to the business index value history database and the scenario execution information, extracts a target scenario whose correlation value with the business index value satisfies predetermined conditions, and generates a correction scenario.

Autonomous control of analyzing business-related data by a robot system

A distance between an autonomously mobile information processing device and an apparatus is calculated based on positional information of the information processing device and positional information of the apparatus installed in a service provision site and necessary for a service to be provided by the information processing device, and the apparatus that is available is determined based on the distance between the information processing device and the apparatus in a case where the information processing device coordinates with the apparatus to provide the service.

Server device, device control method, and recording medium

A robot control system controlling a robot executing a personal service includes: a storage unit configured to store therein in advance trigger action information for which a task to be executed by the robot is formed by a series of actions and the actions and trigger conditions for respectively starting the actions are specified; a trigger determination unit configured to determine whether a trigger condition of the action is satisfied; an action execution unit configured to execute the action; and a task execution unit configured to sequentially select an action specified in the trigger action information of the task to be executed by the robot, cause the trigger determination unit to determine whether a trigger condition of the selected action is satisfied, and cause the action execution unit to execute the action when the trigger condition is satisfied.

Robot control system and robot control method

Selected comb polymers contain specified amounts of macromonomer and nitrogen-containing (meth)acrylates. Lubricant compositions can contain such comb polymers. The selected comb polymers can be used as solubilizers in lubricant compositions, especially in engine oil (EO) compositions.

Lubricating oil composition comprising dispersant comb polymers

In a radio communications apparatus according to the present invention, an RSSI detects the strength of a received signal, and a fading pitch detection circuit detects a fading pitch of the signal from the detected strength thereof and determines whether the moving speed of the terminal apparatus exceeds a predetermined value. A high-speed moving time incoming call control means determines whether the apparatus is moving at high speed based on the determination results of the fading pitch detection circuit. If it is doing so, the control means automatically responds to the incoming call, transmits a response message from a response message storage area to a communication party, and stores a message input by the communication party in a message storage area.
