Title: Oscillator
Inventor: WADAKA SHIYUUZOU
IPC: H03B5/30
Filed: 1987-04-08
Abstract: PURPOSE:To obtain an oscillator with a low phase noise level by constituting the oscillator by connecting plural delay lines of plural resonators in a feedback circuit in series. CONSTITUTION:This oscillator consists of delay lines or resonators 1 which use a surface acoustic wave, a phase shifter 3, a power distributor 4, and an output terminal 5. Then the feedback closed circuit is formed which amplifies the output of the delay lines or resonators 1 and feeds part of it back to the input of the delay lines or resonators 1 through the power distributor 4, and the phase shifter 3 is connected in this feedback closed circuit. Further, the plural delay lines or resonators are connected mutually in series in this feedback closed circuit. When the delay lines are used in this constitution, noises are reduced by obtaining a long delay time by combining the plural delay lines, and when the resonators are used, noises are reduced by increasing the load Q on the whole by combining the plural resonators.

Title: Sound absorbing device of combustion apparatus
Inventor: TAKESHITA SHIROU
IPC: F04D29/66
Filed: 1984-04-27
Abstract: PURPOSE:To contrive to damp the noise by a structure wherein sound-absorbing material is mounted along a wall surface having a M-shape in cross provided on a casing. CONSTITUTION:Combustion air is forced in a burner from a suction louver 6 through a blast passage 7 in an apparatus and the suction port 8 of a fan 4. In this case, because air flow is forcibly deflected near the suction port 8, a recess 14, in which sound-absorbing material 15 is mounted, is placed in a region excluded from the influence of the air flow due to such a structure that only a passage 7 side opposing to the suction port 8 is open and the remaining sides are closed and consequently the sound-absorbing material 15 does not directly contact with the air flow, resulting in enabling to prevent the sound-absorbing material 15 itself from being clogged by the draft and the fine flies of the sound-absorbing material 15 from being sucked in a hot water supplier. On the other hand, directly radiated noise, which is emitted through the suction port 18 as a fan noise, is partly absorbed and partly reflected by the sound-absorbing material 15 mounted along the wall surface of the recess having a M-shape in cross section. However, the reflected noise is damped by repeating the reflections within the space 16 of the recess 14, resulting in suppressing the diffusion in a casing 13 and consequently producing noise attenuation effect.

Title: Manufacture of semiconductor device
Inventor: ITO MASAHIRO
IPC: H01L21/28
Filed: 1991-04-18
Abstract: PURPOSE:To form a contact structure of high diffusion barrier performance by forming a film decomposed by reaction of a high melting point metal film and Si between a high melting point metal film and a silicon layer before nitriding treatment of a high melting point metal film. CONSTITUTION:An SiO2 9 is formed by thermal oxidation over the surface of a necessary region of a high-doped diffusion layer 5 exposed by contact hole formation, and a Ti film 5 is deposited over the whole surface by sputtering. R.T.A heat treatment is made in an N2 atmosphere for about 700 deg.C 30sec to nitrify most of the Ti layer 5 into a TiN film 7. At this time, a TiSi2 layer 6 is formed between the TiN film 7 and the high-doped diffusion layer 3. Thereafter, an Al film 8 is formed over the whole face, the part other than an unnecessary region is patterned together with the TiN film 7 by photoetching. Hereupon, the Ti layer 5 reduces the SiO2 layer 9 gradually, and some of the TiSi2 layer 6 is formed. This process enables suppression of restriction in nitride film thickness and deterioration in junction characteristics.

Filed: 1980-06-25
Abstract: PURPOSE:To stabilize the rotation of a rotary shaft, by connecting the 1st and 2nd flywheels to each other with a spring to obtain a large moment of inertia. CONSTITUTION:In the normal state, a press-bonded part 22 of each of fitments bars 5a and 5b touches the outer circumference face of the 1st flywheel by a spring 10. Both flywheels 1 and 2 are connected into a body by an auxiliary fitment 5. As a result, a large moment of inertia is produced to ensure a stable rotation. Then both levers 7 are turned round a support shaft 23 and in the direction of arrow (a), the upper end part 24 of each of fittings 5a and 5b is pressed downward with a tip 7a of each of both levers 7. As a result, the part 22 gets apart from the outer circumference face of the wheel 1. Thus a rotary shaft 3 is turned only by the wheel 1 to reduce the moment of inertia. As a result, rise can be secured up to a prescribed rotation in a short time.
