Abstract: A contaminant detection system includes a light source configured to emit excitation light on an object to be inspected; a detector configured to detect fluorescence emitted from a contaminant adhering to the object to be inspected; and a processor. The fluorescence is caused by emission of the excitation light from the light source onto the object to be inspected. The processor is configured to perform a determination of a location of the contaminant and a type of the contaminant, based on the fluorescence emitted from the contaminant; and output a result of the determination.

Abstract: Provided is an assembling apparatus for a semiconductor manufacturing apparatus. The assembling apparatus includes: a body; lift attached to the body and configured to move a reaction tube having an opening at a lower end portion thereof vertically, thereby allowing a gas supply pipe to be installed inside the reaction tube through the opening while the reaction tube is held by the lift; gas supply source configured to supply a gas into the reaction tube through the gas supply pipe while the reaction tube is held by the lift; and an exhaust mechanism including a pump configured to exhaust an inside of the reaction tube through the opening, thereby performing a leakage test of the reaction tube while the reaction tube is held by the lift.

Abstract: A method for conveying a reaction tube unit including a vertical reaction tube and a gas supply pipe provided at a distance from an inner wall of the vertical reaction tube along a longitudinal direction thereof, the method includes: arranging a buffer inside the reaction tube between the inner wall and the gas supply pipe to alleviate a collision; placing the reaction tube unit attached with the buffer on a carriage via a vibration isolator; and conveying the reaction tube unit by moving the carriage.

Abstract: In an electromagnetic fuel injection valve for in-cylinder injection, a fuel injection hole is an elongated hole having a major axis and a minor axis, the major axis being curved into an arc shape having a radius that is smaller than a radius of a pitch circle of an inlet of the fuel injection hole. Accordingly, the electromagnetic fuel injection valve can ensure a required flow rate even when a penetrating power is decreased.
