Title: Vapor phase reaction equipment
Inventor: KUBO TAKAYUKI
IPC: H01L21/302
Filed: 1988-04-05
Abstract: PURPOSE:To uniformize the reaction rate on a substrate surface, and enable forming a uniform film on the substrate, by arranging a retaining stand in the manner in which the mounting surface is inclined which respect to the flowing direction of reaction gas, in order to reduce the channel section of the downstream side of the stand. CONSTITUTION:A retaining stand 14 is constituted by joining four fan-shaped members, and has a conical form wherein the mounting surface of a substrate S is inclined at an angle of about 7 deg.. In order to prevent the sliding-down and horizontal sliding of the substrate S, a recessed part fitted to the size of the substrate S is formed at a position on the mounting surface where the substrate is arranged center-symmetrically. A penetrating hole 22 is bored at the center of the retaining stand 14 and its boss part 14a. In the penetrating hole 22, a nozzle part 16 to introduce reaction gas into the center of the reaction chamber 13, and a reaction gas supplying pipe 15 are inserted. When the reaction gas is supplied to the surfaces of the substrates S,..., the reaction gas increases the flow velocity in the downstream, and flows on the substrate surface. Thereby, uniform vapor phase reaction on the whole region of the substrate is enabled.

Title: Television receiver
Inventor: SAITO TATSUO
IPC: H04R1/02
Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To efficiently reproduce a low sound frequency component excellently. SOLUTION: Sub-woofers 104L, 104R that are Kelton type speakers are built in left and right spaces of a cabinet 102 of this television receiver. Ducts 104d of the sub-woofers 104L, 104R are formed to be projected externally from 2nd air chambers 104C respectively and ports 104e at the tip of them are provided to a front face of the cabinet 102. Low sound frequency components from the sub-woofers are emitted to the outside of the cabinet 102 from the ports 104e. Thus, sound quality is not deteriorated because of no production of a standing sound wave in the inside of the cabinet 102.  Furthermore, it is not required to increase the amplification factor for a sound signal to drive the sub-woofers in order to balance low frequency sounds with middle and high frequency sounds because squawkers and tweeters placed in front of the cabinet 102 are not on the same plane as the sub-woofer ports 104e.

Title: Exhaust manifold cooling control device for marine internal combustion engine
Inventor: TOKORO MASAMI
IPC: F01P7/14
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To prevent generation of a water drop in an exhaust manifold in a side of a cylinder reducing objective bank and prevent resulting in deterioration of emission by excessively cooling a cylinder itself, in the case of a cylinder reducing process of a marine internal combustion engine. SOLUTION: When driving of a second bank 4b is stopped by variable cylinder control, a flow of cooling water in an exhaust manifold cooling water passage 18 for cooling exhaust of an exhaust manifold 10 provided in the second bank 2b is decreased by squeezing a throttle valve 28. Thus by decreasing the flow of cooling water, a cooling speed by the cooling water is generated slower than usual. Consequently, a temperature of exhaust stagnated in the exhaust manifold 10 and a temperature of a cylinder of the second bank 4b are prevented from large lowering down. Accordingly, generation of a water drop is prevented with exhaust not leading to a dew point, and emission is prevented from deteriorating even when driving of the second bank 4b is restarted.
