Abstract: A batch CVD method repeats a cycle including adsorption and reaction steps along with a step of removing residual gas. The adsorption step is preformed while supplying the source gas into the process container by first setting the source gas valve open for a first period and then setting the source gas valve closed, without supplying the reactive gas into the process container by keeping the reactive gas valve closed, and without exhausting gas from inside the process container by keeping the exhaust valve closed. The reaction step is performed without supplying the source gas into the process container by keeping the source gas valve closed, while supplying the reactive gas into the process container by setting the reactive gas valve open, and exhausting gas from inside the process container by setting the exhaust valve to gradually decrease its valve opening degree from a predetermined open state.

Abstract: The present invention provides a pneumatic tire with reduced air columnar resonance noise level in comparison with the conventional pneumatic tires. The pneumatic tire comprises large-volume oblong holes 11 formed in a sidewall 10a on one side of a main groove 1 and small-volume oblong holes 12 formed in a sidewall 10b on the other side thereof, respectively, in which a width w1 and a depth d1 of the large-volume oblong hole 11 are at least not less than 0.4 mm and more than 0.05 times but less than 0.25 times a width W of the main groove 1, and a space p1 between the large-volume oblong holes 11 is at least not less than 0.8 mm and more than 0.2 times but less than 1.0 times the width W, a width w2 and a depth d2 of the small-volume oblong hole 12 are at least not less than 0.2 mm and more than 0.01 times but less than 0.05 times the width W, and a space p2 between the small-volume oblong holes 12 is at least not less than 0.4 mm and more than 0.04 times but less than 0.

Abstract: A film formation method of forming a silicon oxide film on a surface of an object to be processed in a process chamber includes absorbing a seed gas comprising a silane-based gas on the surface of the object to be processed by supplying the seed gas into the process chamber, forming a silicon film having an impurity by supplying a silicon-containing gas as a material gas, and an addition gas including the impurity into the process chamber, and oxidizing the silicon film to convert the silicon film into the silicon oxide film. Accordingly, the silicon oxide film having the high density and the high stress is formed on the surface of the object to be processed.

Abstract: In a variable valve apparatus, a second connector has a fifth side surface located below a fourth side surface and further away from a second side surface than is the fourth side surface, so that a width in a direction along a rocker shaft is narrower in a lower portion adjacent to an inlet valve than in an upper portion adjacent a slipper surface. A guide surface is provided in a lower portion of the fourth side surface and includes an arc that is shorter than a semicircle, and coaxial and equal in radius with an engaging hole. Thus, even when a connecting pin is advanced in a state of a through-hole and the engaging hole not being in precise alignment, the forward end of the connecting pin is guided through the guide surface into the engaging hole. An extended period can therefore be secured for advancing the connecting pin, to improve the certainty of connection.

Abstract: An engine includes a cylinder, an exhaust port, an exhaust valve, a secondary air supply pipe, and an electromagnetic valve. The electromagnetic valve is opened in a predetermined time period after a point in time when a lift amount of the exhaust valve reaches about half a maximum value during a time period in which an opening of the exhaust port is opened. This causes air to be supplied from a secondary air supply pipe to the exhaust port.
