Title: Combustion device
Inventor: ISHIBASHI NOBORU
IPC: F23D14/82
Filed: 1985-04-19
Abstract: PURPOSE:To prevent a flame being drawn through flame holes and a back-fire from being produced in case of an occurrence of increased pressure in a combustion chamber to cause an interior of a burner to show a low pressure due to a delay in ignition by a method wherein a mixture gas smoothly plate is arranged between a premixing air supplying hole and flame holes and the mixture gas distribution holes formed in the soothing plate are opposedly installed to the flame holes. CONSTITUTION:To a burner body 5, a gas supplying pipe 7 connected at its lower part, a plurality of air holes are formed at an outer circumference of the upper part thereof, a primary air hole 8 acting as the premixture air supplying port is arranged, and a gas unifying plate 10 having gas supplying holes 9 for dispersing and supplying gas uniformly is arranged between the primary air holes 8 and the gas supplying pipe 7. A burner cap 6 forms a mixture gas regulating plate 14 having a plurality of mixture gas distribution holes 13 and a mixture gas chamber 15, and a large number of slit-like flame holes 16 are formed at the upper part of the burner cap 6. The mixture gas distribution holes 13 are arranged opposed against the flame holes 16, approx. at the middle part, and arranged in such a way as the injected mixture gas from the mixture gas distribution holes 13 is struck at a right angle against the flame holes 16 so as to make a high pressure gradient at the inlet part of the flame holes. In this way, the flame hole inlets has always a high pressure and then a possibility of drawing-in of the mixture gas is eliminated.

Title: Induction light
Inventor: KATSUMATA IKUO
IPC: F21S9/02
Filed: 1989-04-03
Abstract: PURPOSE:To eliminate panel vibration even if the pressure level of sound produced by a speaker is high and avoid emitted voice from being inarticulate by providing a preset gap between a cylinder and a panel. CONSTITUTION:An instrument mainframe 1 is provided with panels 33, on which induction voice emitting holes 32 are formed at the center portions, in an opposite manner on one end of openings 30 formed in both faces thereof, and firmly mounted with a cylinder 36 on the side frame 25. The cylinder 36 is mounted with a present gap (S) to the inside face of the panel 33. Accordingly, speaker vibration is transmitted to the cylinder 36, which is also vibrated, not to bring about the vibration of the panel 33 because of the existence of the gap (S) between the cylinder 36 and the panel 33. It is thus possible to avoid inarticulate voice produced by the speaker.

Title: Manufacture of diffraction grating
Inventor: HIYOSHI YASUO
IPC: G02B5/18
Filed: 1987-04-08
Abstract: PURPOSE:To easily manufacture the diffraction grating of pattern size of submicron at low cost by a light exposure, by setting the size of an incident angle to a substrate for photomask of a luminous flux for exposure, as shown by a specific expression. CONSTITUTION:First of all, on a rotary stage 14, a substrate 2 for photomask, and a substrate 5 for diffraction grating formation in its vicinity are fixed in parallel to each other so that a diffraction grating pattern 3 and a photoresist 4 are opposed. Also, from wavelength lambda of a luminous flux 1 for exposure, and a grating interval LAMBDA of the pattern 3, an incident angle theta0 determined by an equation is set to a stage 14. In such a way, the stage 14 is positioned so that the luminous flux 1 is made incident on the substrate 2 at the incident angle theta0. In this state, when an exposing device is turned on, a light emitted from a light source 11 becomes a parallel luminous flux 1 by a collimator 13, made incident on the substrate 2 at the incident angle theta0 and the pattern 3 is transferred to the photoresist 4. Subsequently, the substrate 5 is removed from the stage 14, and by using an obtained minute pattern as a mask, a quartz glass plate is brought to etching. Next, by eliminating the remaining resist by O2 plasma, etc., a diffraction grating is obtained.

Abstract: PURPOSE:To prevent the vanishing of a wiring layer caused by stress migration between a passivation film and the wiring layer, by forming the wiring layer in a trench of an interlayer insulating film, and flattening the passivation film on the wiring layer. CONSTITUTION:On a semiconductor substrate 1 composed of silicon and the like, a source drain region 4 and an element isolation film 2 composed of SiO2 and the like are formed, and a gate electrode 3 composed of a polycrystalline silicon film is formed on the substrate 1 via a gate oxide film. In order to insulate the gate electrode 3, an interlayer insulating film 5 composed of a PSG film and the like are formed on the whole surface. In particular, in a trench 9 formed in the interlayer insulating film 6, a wiring layer 7 composed of Al and the like are formed, on which a passivation film 8 is arranged. Since the wiring layer 7 is buried in the trench 9 formed in the interlayer insulating film 5, the passivation film formed thereon becomes flat. Thereby the destruction of a passivation film caused by the stress of sealing resin can be avoided.
