Filed: 2001-12-13
Granted: 2003-06-11
Abstract: In a conventional gas valve, an operating rod can be moved forward and rearward in an interior passage such that the flow adjustment of fuel gas can be effected by opening and closing of a gas-opening/closing valve and a flow-adjusting valve. The conventional gas valve cannot set a minimum flow rate according to the type of the fuel gas used so as to prevent the flame of a gas burner from going out. A flow-adjusting valve 6 is constructed so that, after opening of a gas valve 4, an operating rod 3 is moved forward by a predetermined distance such that the flow rate is adjusted based on the distance, by which the operating rod is moved after opening of the gas valve. The flow-adjusting valve supplies gas fuel to a fuel gas discharge portion 17 by means of a bypass passage 9 that is in fluid communication with both an interior passage 15 that is located between a lower stream side of the gas-opening/closing valve and an upper stream side of the flow-adjusting valve, and a gas discharge portion. The bypass passage is formed with an orifice 91 for setting a minimum gas flow rate.

Title: A new method for pre-STI-CMP planarization using poly-Si thermal oxidation
Inventor: HAU PANG CHONG
IPC: H01L21/762
Filed: 2002-02-26
Granted: 2003-07-21
Abstract: A method of forming shallow trench isolations is described. An etch stop layer is deposited on the surface of a semiconductor substrate. A plurality of isolation trenches are etched through the etch stop layer into the semiconductor substrate to separate active areas. An oxide layer is deposited over the etch stop layer and within the isolation trenches wherein the oxide fills the isolation trenches and overlies the etch stop layer on the active areas. A polysilicon layer is deposited overlying the oxide layer within the isolation trenches and the oxide layer overlying the etch stop layer. The polysilicon layer is polished away until the oxide layer overlying the etch stop layer is exposed and the polysilicon layer remains only overlying the oxide layer in the isolation trenches. The polysilicon layer is oxidized whereby the oxidized polysilicon layer has a height close to the height of the oxide layer overlying the etch stop layer. The oxidized polysilicon layer, the oxide layer overlying the etch stop layer, and the oxide layer in the isolation trenches is polished down until the etch stop layer is reached thereby planarizing the isolation trenches to complete planarized shallow trench isolation regions in the manufacture of an integrated circuit device.

Title: Semiconductor laser device
Inventor: TOJO TSUYOSHI
IPC: H01S5/22
Filed: 2002-04-10
Granted: 2003-07-11
Abstract: Disclosed is a nitride based III-V group compound semiconductor laser device of ridge waveguide type with an oscillation wavelength of about 410 nm which has a low driving voltage, a high half-width value Theta// of a FFP in a direction horizontal to a hetero interface, and a high kink level (i.e., good light output-injected current characteristics over the high-output range). This laser device is similar in structure to the related-art semiconductor laser device except for the current constricting layer formed in a ridge. It has a stacked film composed of an SiO2 film (600 Å thick) and an amorphous Si film (300 Å thick) which are formed on the SiO2 film by vapor deposition. The stacked film covers both sides of the ridge and a p-AlGaN cladding layer extending sideward from the base of the ridge. The SiO2 film and Si film have respective thicknesses which are established such that the absorption coefficient of fundamental horizontal lateral mode is larger than the absorption coefficient of primary horizontal lateral mode. This structure results in a higher kink level, while suppressing the high-order horizontal lateral mode, a larger effective refractive index difference Deltan, and a larger value of Theta// without the necessity for reducing the ridge width.

Granted: 2003-09-11
Abstract: A power transmission comprises a continuously variable transmission CVT, which transmits a rotational driving force from an engine to wheels, a starting clutch 5, which sets variably the transmission capacity of the continuously variable transmission, and a control valve CV, which controls the engagement actuation of the starting clutch 5. While a vehicle equipped with this power transmission is decelerating, the engagement of the starting clutch is controlled to transmit a rotational driving force from the wheels to the engine. Specifically, the engaging capacity of the starting clutch is controlled to bring the difference between the input and output rotational speeds of the starting clutch into a predetermined range, and the control pressure of the starting clutch that brings this difference in the predetermined range is learned, i.e., stored in memory and renewed, as a control value for the next deceleration of the vehicle.
