Abstract: A secondary battery includes a battery case, an electrode group, and nonaqueous electrolyte. An outer diameter R ranges from 3.0 to 6.5 mm. A ratio r/R of an inner diameter r of a hollow in the electrode group to an outer-diameter R ranges from 0.1 to 0.3. The nonaqueous electrolyte includes at least one selected from LiSO3F and LiFSI. In the case that the nonaqueous electrolyte includes LiSO3F, the concentration of LiSO3F is 1.5% by mass or less in a case that the outer-diameter R ranges from 3.0 to 5 mm, and is 1.2% by mass or less I a case that the outer-diameter R is more than 5 mm and is 6.5 mm or less. In the case that the nonaqueous electrolyte includes LiFSI, the concentration of LiFSI is 1.1 mol/L or less in a case that the outer-diameter R ranges from 3.0 to 3.5 mm, and is 1.0 mol/L or less in a case that the outer-diameter R is more than 3.5 mm and is 6.5 mm or less.

Abstract: A dust core includes a metal magnetic powder and a binding agent that binds particles of the metal magnetic powder. The binding agent includes a silicone resin and an epoxy resin. In an elemental analysis of the dust core based on an image of a cross section of the dust core, when a silicon (Si) element and a carbon (C) element are detected on a weight basis at 15 measurement points between the particles of the metal magnetic powder in the image, a difference between a maximum value and a minimum value of x/(x+y) values at the 15 measurement points is at most 0.243, where x denotes an amount of the Si element detected and y denotes an amount of the C element detected.

Abstract: A passing determination device acquires a first captured image obtained by repeatedly capturing an image of a region including a passing determination position of a trailer from a front of the trailer in a traveling direction of the trailer, and detects the trailer from the first captured image. Further, the passing determination device includes a processor configured to determine that the trailer detected from the first captured image captured at a first time passes through the passing determination position when the trailer is detected from the first captured image captured at the first time and the trailer is not detected from the first captured image captured within a first time period from the first time.

Abstract: An inspection device (12) for a cold insulator (10) includes: an RF reader 50 that receives from an RF tag 30 a detected temperature of a cold insulator in a cold insulation box, the detected temperature being detected by a temperature sensor (20) attached to a surface of the cold insulator; and a controller 61. The controller outputs information indicating a result of comparison between: at least one of a lower limit temperature obtained by adding a predetermined first value to a lowest management temperature of an article that is kept cold in the cold insulation box and an upper limit temperature obtained by subtracting a predetermined second value from a solidification temperature of the cold insulator; and the detected temperature of the cold insulator which has been received by the RF reader.

Abstract: A rotary compressor 100 includes a drive shaft 101 having an eccentric shaft 101a, a piston 102 fitted onto the eccentric shaft 101a, a cylinder 103 that receives the eccentrically rotating piston 102, an upper end plate 104 and a lower end plate 105 that close the upper and lower opening surfaces of the cylinder 103, a vane 106 that divides a space formed by the cylinder 103, the piston 102, the upper end plate 104, and the lower end plate 105 into a suction chamber 113 and a compression chamber 114, a discharge space 117 that is formed by causing the cover 108 to close a recessed portion 107 obtained by recessing a surface of either the upper end plate 104 or the lower end plate 105 on the opposite side to the cylinder 103 and where discharge gas flows in from the compression chamber 114 and directly flows out to the outside of the compressor 100, and spatial volume of the discharge space 117 having 10 times enclosed volume of the cylinder 103, thereby reducing noise and vibration due to discharge pulsation as well as improving efficiency and reliability and reducing cost.

Abstract: An intraoral camera includes an imaging unit, an illuminator, and an illumination controller. The imaging unit generates image data by capturing an image of a tooth inside the mouth of a user. The illuminator illuminates the tooth. The illumination controller controls at least one of the illumination intensity or the color temperature of the illuminator to bring the color temperature of reflected light from the tooth that is based on the image data, closer to a target color temperature based on the second color temperature of the illuminator.

Abstract: A coil includes: a strand-wound body configured with stacked n turns of a wound strand that is made of a conductor and has a quadrangular cross-section, where n is a natural number; and an insulating resin covering a surface of the strand-wound body. An i-th turn, where i is an integer and 1≤i≤n, has a quadrangular ring shape having four side portions, and in the i-th turn, the insulating resin covers a surface of each of the four side portions. In the first to n-th turns, the insulating resin is continuously and integrally formed.

Abstract: A vehicle approach notification system includes a filter; a notification sound controller which generates a signal corresponding to a notification sound for notifying of approaching of a vehicle, based on a sound signal obtained from a notification-sound sound source; and a setter which obtains vehicle information of the vehicle, and sets, according to the vehicle information, at least one of the notification-sound sound source to be used in generation of the notification sound, a filter property to be applied to the filter, or a control parameter to be applied to the notification sound controller in generation of the notification sound. The notification sound controller outputs the signal generated, through the filter to an exterior loudspeaker provided to the vehicle.
