摘要:
An LED light source vehicular lamp can include a plurality of LED modules each having respective appropriate light distributions. The modules can be attached to a housing to form a light distribution characteristic through combination of the light emitted from the LED modules. At least part of the LED modules can include an illumination axis that is substantially at a right angle to the optical axis of the lamp such that light reflected at a reflector provided in the housing travels in the illumination direction of the LED light source vehicular lamp. The LED modules can also include a rear end that protrudes from an outer surface of the housing to improve the heat radiation efficiency, which enables the use of LED chips that can use higher permissible current values.

The present invention provides a plasma etching method that can etch a metal film as a material to be etched selectively against anorganic film underlying the material. The etching method comprising the steps of introducing an etching gas in an etching chamber wherein a material to be etched is placed, and exciting the etching gas to a plasma state to etch that material to be etched, wherein the material to be etched is a metal film 3 consisting of Au, Pt, Ag, Ti, TiN, TiO, Al, an aluminum alloy, or a laminated film of these films laminated on an organic film 5; and the etching gas is a mixed gas containing at least a gas selected from a group consisting of Cl2, BCl3, and HBr; and at least a gas selected from a group consisting of CH2Cl2, CH2Br2, CH3Cl, CH3Br, CH3F, and CH4.

A high-dielectric-constant gate insulating film 32 such as HfO2 is etched with gas plasma using gas selected from Ar gas, He gas, Ar+He mixed gas, and mixed gases formed by mixing CH4 with the preceding gases while maintaining a temperature of 40° C. or higher, thus ensuring high etching selective ratio between a HfO2 film 32 and a Poly-Si layer 33, a substrate Si layer 31 and a SiO2 mask 34, reducing the amount of loss of the substrate Si layer 31 and side etching of sidewalls of the Poly-Si gate portion 33 during plasma etching of HfO2.
摘要:
An air mattress includes a first through a fourth sheets (6, 7, 8, and 9), respectively, which are bonded together along the peripheries thereof and at a multiplicity of bonding spots, creating a triple-layer air cell structure consisting of a first, a second, and a third air cells (13, 15, and 17), respectively. A multiplicity of first bonding spots (10) bonding the first and second sheets together are spaced apart at regular intervals along longitudinal and transverse lines such that four neighboring spots occupy four corners of a tetragon. On the other hand, a multiplicity of second bonding spots (14) bonding the second and the third sheets together are arranged at positions which correspond to the centers of the tetragons. The third air cell has the same structure as the first air cell. These air cells are inflated such that the third air cell maintains high a pressure, while the first and second air cells maintain a low pressure. The low pressure air mattress may effectively prevent bedsores.

A method for producing X(BaZ.Sr1-Z)(Zn⅓.(TaM.Nb1-M)⅔)O3—Y(BaZ′.Sr1-Z′)(Ga½.Ta½)O3 solid solution system, characterized in that sintering is carried out at a temperature of 1400° C. to 1550° C. in an atmosphere of N2 containing oxygen in a concentration of 6% to 40% or sintering is carried out at a temperature of 1400° C. to 1550° C. after presintering at a temperature of 900° C. to 1300° C. This method is suitably used in order to constantly produce a dielectric porcelain composition for an electronic device which has a reduced temperature coefficient of resonance frequency and an excellent specific dielectric constant, and is uniform with respect to the quality distribution in one composition, by suppressing the evaporation of the Zn contained in a conventional porcelain composition of a perovskite type compound and adjusting the oxygen concentration in an atmosphere for sintering to a specific value without controlling a composition.
