Abstract: An information processing apparatus (1) included in a welding training system includes a transmittance adjuster (14) capable of adjusting a transmittance of a window of a welding helmet in virtual space in multiple grades, and a display controller (17) configured to cause a display of an HMD (2) to display a situation of a welding operation in the virtual space at an illuminance corresponding to the adjusted transmittance. The transmittance adjuster (14) adjusts the transmittance based on a skill level of a trainee determined by a skill level determination unit (13).

Abstract: A dropping nozzle includes: a flow passage part that includes a flow passage that molten glass passes through; and an opening part that includes an opening that communicates with the flow passage, the opening part dropping the molten glass as a glass drop, wherein the opening includes a plurality of inclined parts in which adjacent inner inclination angles are different from each other in a section parallel to a center axis of the flow passage part, and from among the plurality of inclined parts, a first inclined part that is closest to the flow passage part has an inner inclination angle that is smaller than an inner inclination angle of a second inclined part that is farthest from the flow passage part.

Abstract: Provided is an electric conduction system and a male terminal that prevent arc discharge by cutting off power supply prior to the occurrence of arc discharge. The male terminal is connected to the female terminal of the electric conduction apparatus, and power is supplied from the electric conduction apparatus. The male terminal includes a first resistance portion having a resistance value R1 on its rear-end side and a second resistance portion having a resistance value R2 on its front-end side. Accordingly, the resistance value of the power supply path varies depending on the amount the male terminal is inserted into the female terminal. By determining whether the electric current amount varies in accordance with a change in the resistance value of the power supply path, the electric conduction apparatus can cut off power supply prior to the male terminal coming off the female terminal, thus preventing an arc discharge.

Abstract: A grounding terminal unit (A) is sandwiched between a seating surface (S) of a bolt (B) and a grounding part (E) with first connecting plates (13) of a first grounding terminal fitting (10) and second connecting plates (43) of a second grounding terminal fitting (40) placed one over the other in a plate thickness direction. The first grounding terminal fitting (10) is configured by uniting two divided fittings (20, 30) including tabs (19) connectable to first conductive paths (Wa) and the two divided fittings (20, 30) are formed with uniting locking portions (25, 33) for holding the two divided fittings (20, 30) in a united state by being locked to each other at a position different from the first connecting plates (13). The first connecting plates (13) are in the form of single plates with the two divided fittings (20, 30) united.

Abstract: A conduction path (20) is formed by connecting a coated wire (26), in which a conductor (27) is surrounded by an insulation coating (28), to a rear end part of a terminal fitting (21) and the entire terminal fitting (21) and a front end part of the coated wire (26) are to be accommodated into a housing (10). The conduction path (20) includes a coating layer (29) made of a photocurable resin, provided in an area of the coated wire (26) to be accommodated into the housing (10), thinner than the insulation coating (28) and surrounding an area of the conductor (27) where the insulation coating (28) is removed.
