The control section causes the provision section to provide the information regardless of whether or not the user has issued a request in a case where a situation that should be understood by the user is detected.

Abstract: Information presentation that enables a subject to recognize information more easily is performed. A control system includes a control unit that controls presentation of information in a presentation unit that presents the information, in which the control unit controls a mode of the presentation in the presentation unit according to the information to be reported to a subject.

Abstract: A user is allowed to intuitively visually recognize information that is beneficial to the user. There is provided a control device including a control unit configured to control presentation of information using a presentation unit, in which the control unit causes the presentation unit to present beneficial information that is beneficial to a user as the information. In addition, there is provided a presentation system including: a presentation unit configured to perform presentation of information to a user; and a control unit configured to control of the presentation of information using the presentation unit, in which the control unit causes the presentation unit to present beneficial information that is beneficial to the user as the information.

Abstract: To allow a user to more intuitively grasp processing executed in accordance with an operation. There is provided a control device including: a reception unit that receives an operation on at least one operation unit, and a control unit that sets, as a specific function, a function of executing at least one processing in accordance with contents of the operation received by the reception unit, and controls a notification unit to perform a notification in accordance with each of processing executed by the specific function.

Abstract: Operability is further improved. There is provided a control device that includes: an acceptance section configured to accept an operation on at least one operation section; and a control section configured to control a notification section to perform notification matching a situation of a series of continuous operations accepted by the acceptance section.

Abstract: [Object] To further improve operability. [Solution] Provided is a control device including: a reception section configured to receive an operation performed on at least one operation section; and a control section configured to execute a notification process of controlling a notification section in such a manner that the notification section treats at least one of images displayed on a display section as a target image and makes a notification in tandem with the at least one target image that moves depending on a content of the operation received by the reception section. The operation section and the display section are arranged at respective positions where it is difficult for a user to intuitively understand a correspondence between operation coordinates and display coordinates, the operation coordinates defining a position of the operation performed on the operation section, the display coordinates defining a position of the image displayed on the display section.

Abstract: A positioning mechanism is provided for a moving member that moves linearly by the turning of a screw member driven by a stepping motor. A drive shaft driven to turn by the stepping motor is fitted, so that turning transmission is possible, into the screw member that screws into the moving member that is capable of moving linearly. A configuration prevents the moving member from turning together with the screw member when the screw member is turning. Origin positioning is performed, by using a stopper, by stopping the linear movement of moving member caused by driving the motor to turn in one direction. The moving member is positioned according to the turning steps of the motor in the other direction after the origin positioning. The drive shaft is fitted into the screw member via an elastic member interposed therebetween so that turning can be transmitted.

Abstract: It is an object of the invention to provide a structure of an internal thread portion for preventing looseness which structure allows a reduction in the torque required for the threaded engagement with an external-thread member and prevents a seizure. An exit end portion of a self-locking nut is taperingly contracted over the entire circumference thereof so as to form a contracted internal thread portion having a conical section. In addition, ridges of the contracted internal thread portion are provided with corrugation continuing circumferentially. The diameter of an inscribed circle which links the extremities of projections in the corrugation is smaller than the minor diameter of the external-thread member which is to be engaged threadedly with the internal thread portion.

Abstract: The nut has a tool engaging region or a hexagonal region and a flange region provided on a thread end of the hexagonal region. A sloped step sloping at an angle to the center line of the nut is provided on the thread end. The sloped step (surface) is thus shaped of the annular form on the inner wall of the nut adjacent to the nut opening which faces outwardly of the nut and substantially extends along the loop.

Abstract: A hydraulic power steering device responsive to the speed of a vehicle and comprising a housing, an output shaft disposed in the housing, an input shaft disposed in the housing and coaxial with the output shaft, a torsion bar provided between the output shaft and the input shaft, a control valve provided around the input shaft for controlling the amount of pressure oil to be supplied from a hydraulic pump to a power cylinder in accordance with the torsion of the torsion bar, and plungers each slidably fitted in a hole formed in the output shaft, each of the plungers being adapted to be pressed at its forward end against the input shaft by oil pressure in accordance with the vehicle speed to obtain a reaction. At least one of the portion of the plunger slidable in contact with the inner peripheral surface of the output shaft defining the hole and the portion of the plunger to be pressed into contact with the input shaft is made of a synthetic resin.

Abstract: A system and method for controlling multiplex communication between a master station and a plurality of slave stations, in which a predetermined signal (dummy signal) is transmitted to the plurality of slave stations via a communication circuit (serial bus) from the master station when the master station does not communicate with any one of the slave stations. The predetermined signal indicates that the master station is operating normally, and each slave station receives the predetermined signal derived from the master station via the communication circuit so that each slave station may determine that the master station and communication circuit are operating normally.
