Title: Production of wear-resistant member
Inventor: NISHIHARA HISAKATSU
IPC: B22F3/14
Filed: 1986-07-04
Abstract: PURPOSE:To produce a wear-resistant member having an intricate shape by thermally spraying an Fe-Ni alloy contg. Ni at a limited ratio onto the surface of a metallic base material, pressing a canning material packed with a wear-resistant material thereon and subjecting the materials to hot hydrostatic pressurizing and sintering. CONSTITUTION:An intermediate layer 20 is formed on the surface of the metallic base material by thermally spraying the Fe-Ni alloy contg. 25-36at% Ni onto said surface. The coefft. of thermal expansion of the intermediate layer 20 obtd. by adjusting the Ni content of the above-mentioned alloy is adjusted to the intermediate of the respective coeffts. of thermal expansion of the above-mentioned metallic base material 10 and the under-mentioned wear- resistant material layer. The canning material 4 is then pressed to the intermediate layer 20 to delineate the space part for forming the wear-resistant material layer on the surface of the intermediate layer 20. The wear-resistant material 30 consisting of a uniform powder mixture composed of self-fluxing alloy powder of an Ni-Cr alloy, etc., and ceramic powder of WC, etc., is packed into said space part. While the inside of the space part is deaerated, the space part is hermetically sealed and the base material is subjected to the hot hydrostatic pressurizing and sintering. The dense and securely bonded wear-resistant material layer is thereby formed even on the base material 10 having the intricate surface shape via the intermediate layer 20 having a uniform film thickness.

Title: Assembly method of vibro-isolating pulley
Inventor: ITOU NORIO
IPC: F16H55/14
Filed: 1979-12-06
Abstract: PURPOSE: To impart fall-off resistance and torque durability to a vibro-isolating pulley, by providing convex and concaved parts of suitable size on the contact surface of a boss with a rubber layer of a pulley part.  
     CONSTITUTION: The periphery of a boss 3 and inner circumference of a pulley part 2 are formed, for instance, to a round shape, and in 4 positions on the shaped part, for instance, protrusively shaped parts 2a, 3a are formed correspondingly to the boss 3 and the pulley part 2, while in the rubber layer 4 making contact with the boss 3 and the pulley part 2 a suitable shape of ruggedness is provided. The contact face, being formed in such a manner as in the above, can remarkably increase the contact area to improve the fall-off resistance of a vibro-isolating pulley 1 in use because of the increase of friction resistance in the contact part. While the rubber 4 placed in the concaved part, when it rides over the protrusively shaped parts 2a, 3a, produces a large amount of resistance to impart torque durability in addition to the fall-off resistance, then the vibro-isolating pulley, manufactured by the method of press-fit assembly inferior in adhesiveness, can obtain satisfactory fall-off resistance and torque durability.

A stripe- shaped mask of SiO2 24 2-3mum wide is applied thereafter in the direction <011>, and etching is made thereon down to the InP substrate by a mixed solution of Br2-CH3OH, whereby a V-shaped groove 26 is obtained. Next, after the SiO2 film 24 is removed by HF, only the InGaAsP layer 23 is removed by a mixed solution of HF-HNO3. Thereby a V-shaped groove 26' about 2mum wide, narrower than the width 25 of the mask, and about 1mum deep can be formed with excellent reproducibility on the InP substrate.

Title: Image decoding method and image decoder
Inventor: BRAMLEY RICHARD
IPC: H04N7/50
Filed: 1999-06-07
Abstract: PROBLEM TO BE SOLVED: To eliminate errors due to memory addressing by storing an address of a related packet with an identifier to specify an image, executing first decoding of the image, reading a packet instructed by the stored address again, detecting the identifier specifying the image and executing 2nd decoding of the image. SOLUTION: A microprocessor MP stores an address  1 of a packet, including an image start identifier PSC 2 with respect to an image IM2 and a temporal reference TR2 to registers RG1, RG2.

Title: High frequency output level varying circuit
Inventor: TAUCHI NOBUTAKA
IPC: H03G3/00
Filed: 1990-06-18
Abstract: PURPOSE:To reduce power consumption when an output level is set at a low level and to obtain stable output by preventing a noise factor deteriorating by varying the output level by controlling the operating point of a supply voltage to a transistor which comprises a high frequency amplifier. CONSTITUTION:A bias voltage is supplied to a base-grounded type bipolar transistor or FET via the transistor for DC voltage stabilization. The bias voltage is varied by a Zener diode 9 and a Zener voltage control circuit 10. The fluctuation 15, 15A, and 15B of the output level generate only micro output fluctuation in each output level even when a high frequency power inputted to an input terminal is varied as shown in input power range 14, and also, when the output level is decreased, the power consumption in the bipolar transistor is decreased. Also, an amplification operation is always performed in the neighborhood of a saturation point even when the operating point of the bipolar transistor is varied as input/output characteristics 11, 12A-12C, therefore, a highly stable output level can be obtained.

Abstract: PURPOSE:To increase impurity concentration in an emitter region and make the gradient of impurity concentration in an emitter-base junction steep, and to improve a current amplification factor by coating the emitter region with a silicon nitride film and thermally treating the whole. CONSTITUTION:A silicon oxide film layer 4 is formed on the surface of an n type epitaxial layer 2 shaped on a p type substrate 1, and the ions of a p type impurity are implanted into an emitter region and a collector region while using a photo-resist layer 11 as a mask. The resist layer 11 is removed, a silicon nitride film 12 is formed, and the film 12 is removed with the exception of the upper section of the emitter region. When the whole is thermally treated in an oxidizing atmosphere, impurity concentration in the emitter region is high because the intrusion of oxygen is prevented by the film 12 in the emitter region, and diffusion depth is also made smaller than the collector region. Accordingly, the gradient of impurity concentration in an emitter-base junction in made steep, and a current amplification factor is increased.
