Abstract: A quality improvement support apparatus that supports improvement in quality of a product produced by a production facility, including: a display unit that displays production condition information in which identification information, operation instruction state information, and a condition evaluation index are associated with each other for each operation instruction, the identification information identifying an improvement target that is a production member or a component included in the production facility and that is to be improved to improve quality of the product, the operation instruction state information indicating a state of an operation instruction to perform an operation in relation to the improvement target, the condition evaluation index being an index for evaluating conditions of the production facility relating to the quality of the product; and an additional operation instruction accepting unit accepting an additional operation instruction for additionally giving an instruction to perform an

Abstract: To be self-propelled in a simple configuration and to perform manual operation smoothly and briskly. A driving wheel includes: a base portion; a rotating shaft (first shaft) rotatably provided with respect to the base portion; a rotation member rotatably provided around the rotating shaft; a drive shaft (second shaft) provided on the rotation member orthogonally to the rotating shaft; a drive wheel provided on the rotation member and rotatable around the drive shaft; a drive unit provided on the rotation member and configured to rotationally drive the drive wheel; and a lock mechanism configured to permit rotation of the rotation member with respect to the base portion, and meanwhile, to deter the rotation of the rotation member with respect to the base portion.

Abstract: Provided are an autonomous running device, a running control method for the autonomous running device, and a running control program of the autonomous running device that allow the autonomous running device to reach a destination while continuing estimation of its self-position. An autonomous running device includes a first position estimation unit that estimates the position of the autonomous running device on the basis of information about surroundings of the autonomous running device, produces information about the estimated position of the autonomous running device as first positional information, and updates the first positional information, a second position estimation unit that estimates the position of the autonomous running device on the basis of rotation amounts of wheels, produces information about the estimated position of the autonomous running device as second positional information, and updates the second positional information, and a control unit.

Abstract: A self-propelled device, control method, and control program therefor are provided. The method and control program each include: position estimation; determining an intersection point of a virtual path connecting start and end points and a straight line passing through a position of the device, orthogonal to the virtual path; determining an offset reference point between the intersection point and the end point; determining at least each of two offset points offset on a corresponding goal point side or a start point side of the offset reference point on the virtual path; determining at least two target points reached by rotating the offset points by 90° about the offset reference point; and causing the device to travel toward the target points.

Abstract: A self-propelled device capable of autonomously traveling on the left side or right side of a virtual path, a method of controlling traveling of the self-propelled device, and a computer program of controlling traveling of the self-propelled device are provided.

Abstract: The present invention provides an email multicasting device which changes a distribution interval of emails dynamically in accordance with the number of emails to be multicast. The email multicasting device pre-stores on a client basis, mobile numbers of users which are destinations of an email. The email multicasting device, when receiving mail contents from a client, creates plural emails each of which contains the mail contents and one of mobile numbers associated with the client, and queues the emails in a buffer area. The queued emails are distributed sequentially at predetermined time intervals by the email multicasting device.

Abstract: The invention provides an information presentation system and information presentation method capable of presenting information suitable for user's preference. An information presentation system 1 comprises a user information DB 9 storing a telephone number of each user terminal and user attribute information in association with each other, a gateway 11 for acquiring an access address URL and a telephone number with reception of an access request for access to an external site from a user terminal, and an access characteristic collecting part 17 for selecting user attribute information, based on the telephone number, and for sequentially updating a marketing information storage part 15 while associating the user attribute information with the access address URL. When a user terminal accesses a portal site, introduction information based on the information stored in the marketing information storage part 15 is displayed on the user terminal, based on the user's attribute.
