Abstract: A tire state determination system can acquire, from a vehicle, state data including various types of information that may exert influence on deterioration of a base body portion of a tire, can calculate, based on the acquired state data, an evaluation value S indicating a state of the base body portion of the tire, and can determine reusability of the tire based on the evaluation value S.

Abstract: A tire state determination system (100) acquires, from a vehicle (50), state data that includes various types of information that may exert influence on deterioration of a base body portion of a tire (1), and calculates an evaluation value S that indicates a state of the base body portion of the tire (1), based on the acquired state data. This allows an inspector who inspects an applicability to a base tire, to preliminarily grasp, as a material for determining whether it can be used as the base tire, the state of the base body portion of the tire.

Abstract: A tire air pressure management system (100) includes: an acquisition processing portion (61) that acquires an air pressure and an air temperature of a tire (11) attached to a vehicle (1); a correction processing portion (62) that corrects the air pressure that has been acquired by the acquisition processing portion (61) together with the air temperature, based on a difference between the air temperature and a predetermined reference temperature; and a first output processing portion (63) that outputs determination information that is generated based on the air pressure after correction by the correction processing portion (62) and is used to determine whether or not the tire (11) needs air pressure adjustment.

Abstract: A tire management system (100) includes: a first communication apparatus (2) that acquires state information regarding a state of a tire (11) that is transmitted from an air pressure detection device (12) provided in a vehicle (1) when the vehicle (1) is located in a communication range of a predetermined wireless communication standard; and a management server (4) including a storage processing portion (70) that stores, into a storage portion (43), the state information acquired by the first communication apparatus (2).

Abstract: A tire management system (100) includes: an acquisition processing portion (62) that acquires state information regarding a state of a pneumatic tire (11) attached to a vehicle (1); a detection processing portion (63) that detects an abnormality of the pneumatic tire (11) based on the state information acquired by the acquisition processing portion (62); and a first output processing portion (64) that, when the detection processing portion (63) has detected the abnormality, outputs first route information to a display portion of a vehicle-mounted communication apparatus (13) of the vehicle (1), wherein the first route information includes a first route that is a route to, among a plurality of predetermined stop spots, a specific stop spot that has a stop space corresponding to a size of the vehicle (1).

Abstract: A surface light-emitting device includes: a light guide plate including a notch; a reflection sheet including a notch; a point light source; a light-source substrate; a first chassis covering and extending along the light-source substrate and the lower surface of the light guide plate; a second chassis formed to fit with the first chassis; a liquid crystal panel put on the second chassis; and a third chassis covering the liquid crystal panel and a part of the first chassis on which the light-source substrate is put, and formed to fit with the first chassis on the part. The light-source substrate is fixed on the first chassis. The first chassis includes a protrusion to be engaged with the notches so as to be moved together with the light guide plate and the reflection sheet in response to a movement of the first chassis along the light guide plate.

Abstract: A planar light emitting device (PLED) includes: a light guide plate (LGP) having upper/lower surfaces; a light source substrate (LSS) mounted with a point light source parallel with a side end of the LGP; a first chassis covering a back of the LSS and a lower surface of the LGP in parallel; and a second chassis having an emission opening; a light source member in a side surface of the PLED; and a fixing member on the side of the PLED with an inclined portion. The inclined portion of the fixing member is formed so pressing the fixing member moves the LGP toward the LSS, which is fixed between the side end of the LGP and the first chassis. Removing the fixing member forms a gap between the LSS and the side end surface of the LGP or the first chassis, and the LSS can exit the LSS take-out portion.

Abstract: A surface emitting device includes a light guide plate having a light outgoing surface and a reflection surface and an LED light source that includes an LED element provided so that light from the LED element enters the light guide plate through a light incoming end surface of the light guide plate. The light guide plate includes a concave portion corresponding to the LED element on a side of the reflection surface just in front of the LED light source. The concave portion has dimensions in which a width of the light guide plate is equal to or larger than a width of a light outgoing surface of the LED element, and a depth from the reflection surface in a thickness direction of the light guide plate is set so that the concave portion does not overlap with a region opposed to the light outgoing surface of the LED element.
