Abstract: A sulfonium salt of specific structure has a high decomposition efficiency and a high acid diffusion controlling ability upon exposure. A resist composition comprising the sulfonium salt offers a high sensitivity, reduced LWR and improved CDU independent of whether it is of positive or negative tone.

Abstract: A lever-type connector according to one aspect of the present disclosure is provided with a housing including an opening and a lever. The housing includes a pair of side walls and a pair of coupling walls. The lever includes a pair of arm portions and an operating portion. The lever attaches and detaches the housing to and from a mating connector as being rotated between a first position where the lever is upright with respect to an axis of the housing and a second position where the lever is inclined away from the opening. The housing and the lever include first restricting portions for restricting rotation of the lever from the first position toward the opening by interfering with each other. The first restricting portions include the coupling wall facing the operating portion with the lever located at the first position.

Abstract: An object of the present invention is to provide a control device and control method that make it possible to perform an inter-device authentication process more certainly and improve security. Provided is a control device including: a control section configured to control an authentication process of performing a process related to device authentication together with at least one communication device on a basis of information included in a signal received through wireless communication with the communication device. The control section performs control in such a manner that authentication information is changed for each process group in which the authentication process is repeated more than once, the authentication information being information to be used for the authentication process.

Abstract: A control device comprising, a control section configured to control an authentication process of performing a process related to device authentication together with at least one communication device on a basis of information included in a signal received through wireless communication with the communication device, wherein the control section performs control in such a manner that a signal including authentication information that is information to be used for the authentication process is transmitted to the communication device through the wireless communication, the authentication information varying depending on signal types, which are types of roles of signals to be transmitted to the communication device in the authentication process.

Abstract: A method and an apparatus for manufacturing a rotor of an electric motor are provided to obtain an electric motor with high efficiency. To this end, a rotor is magnetized by using a magnetizing device. The rotor includes a rotor magnet disposed in the circumferential direction of a rotor shaft, and a position detecting magnet disposed side-by-side with the rotor magnet with respect to the axial direction of the rotor shaft. The magnetizing device includes a rotor-magnet magnetizing yoke and a position-detecting-magnet magnetizing yoke that generate two magnetic fields. The two magnetic fields each have unlike poles arranged alternately in the circumferential direction and have a phase difference relative to each other in the circumferential direction. A phase difference is thus provided between the poles of the rotor magnet and the poles of the position detecting magnet.

Abstract: Measurement reference lengths of length and width are set with respect to a convex structure, and an average of vertical distances between tip points and bottom points inside a measurement reference area is calculated as an average height. An average of horizontal distances between the tip points and bottom points is calculated as an average distance. A value obtained by dividing the average height by the average distance provides a gradient ratio. An inverse tangent of the gradient ratio provides an average gradient angle. When the average gradient angle ranges from 5 degrees to 15 degrees and a standard deviation of average gradient angle ranges from 30% to 40% of the average gradient angle, a regular reflectance at a regular reflection angle with respect to incident light of an angle of 30 degrees from a normal direction of the film surface is 1% or less.
