Abstract: An estimation system generates, from a value of a time series of an estimation object in a past period, a plurality of patterns of a transition of a value of the estimation object. Based on the plurality of generated patterns and a value of a time series of a factor in the past period, the estimation system specifies a dependency relationship between a transition pattern and a value of the factor and a transition pattern at a past (or future) time point and identifies a model in accordance with the specified dependency relationship. By inputting a value of a time series of the factor in a future period to the estimation model, the estimation system specifies a time series of a value in the future period of the estimation object using at least one transition pattern.

Abstract: A travelling control system includes a plurality of vehicles each including a controller, a server including a generator configured to generate a travelling control information for the plurality of vehicles, a predictor configured to predict a merging interference between a first vehicle travelling from a merging road toward a main road and a second vehicle travelling on the main road, a sender which is provided in the first vehicle to send an interference suppressing request, and a receiver which is provided in the second vehicle to receive the interference suppressing request. The controller of the second vehicle travelling on the main road is configured to execute interference suppressing control of suppressing an approach of the second vehicle to the first vehicle travelling from the merging road to the main road, in a case that the receiver receives the interference suppressing request from the first vehicle.

Abstract: Relating to a stepping motor to be used for paper feedings or type head movements in office automation apparatus such as printers or typewriters.A stator (1) is constituted by moulding stator yokes (2), (3), (4), and (5) monolithically by resin with using their inner radius as their reference, and one side of a rotary shaft (11a) of a rotor (11) is supported by a bearing (12a) of a bearing holder member (1a) which is provided on the one-side end plane of a cylinder member of sad stator (1), and at the same time, a bracket (14) holding a bearing (12b) supporting one side of the rotary shaft (11a) of the rotor (11) is inserted into an opening side inner part of said cylinder member.By the above constitution, centering of the rotary shaft can be carried out easily and the gap between the rotor and the inner radius of the stator can be maintained also easily, then as a result of it, low-cost and high-quality stepping motors can be offered.
