IPC: A01D61/00
Filed: 1999-08-26
Abstract: PROBLEM TO BE SOLVED: To reduce cost while simplifying the structure of a scraping rotor and the structure around of a rotary shaft thereof by improving the sprocket structure. SOLUTION: A ring-like sprocket 10 to be installed in a cylindrical rotary part of a packer is formed by overlapping thin sprockets 77 respectively formed of two 180-degree half ring-like split sprocket parts 78 made of a plate with each other in opposite directions. In order to prevent the overlap of joint parts (r) of two split sprocket parts 78 with each other in the vertical direction, upper and lower split sprocket parts 78 are arranged while being displaced at about 20 degree so that the split sprocket parts 78 overlapped with each other in the vertical direction reinforce the joint part (r) of each other, and fitted to a rotating part by six bolts. Four split sprocket parts 78 of one kind and six bolts can form a sprocket 10c having the sufficient strength at a low cost.

Abstract: PURPOSE:To obtain a low-resistance ohmic contact by forming a titanium film on an insulating film and in a connecting hole by using the ion plating method after removing a natural oxide film on the surface of a conductor area exposed on the bottom of the connecting hole and forming a titanium silicide on the bottom of the connecting hole by heat treatment. CONSTITUTION:After forming element separating areas 12 and conductor areas 13 on a semiconductor substrate 11, an insulating film 14 is formed and a connecting hole 15 is formed at a desired location. Then a natural oxide film on the surface of the conductor area 13 exposed on the bottom of the hole 15 is removed by treating the oxide film with a fluorine-containing cleaning solvent. After removing the oxide film, a titanium film 16 is formed on the insulating film 14 by using the ion plating method and a titanium nitride film 17 is formed on the film 16 by using the sputtering method. Then a titanium silicide 18 is formed on the bottom of the connecting hole 15 by performing annealing with a lamp in a nitrogen atmosphere. Therefore, a low-resistance ohmic contact can be realized, because the boundary between the conductor area 13 and titanium silicide 18 is free form any oxide film.

Title: Vacuum conversion of caramel
Inventor: DEGUCHI YOSHIMITSU
IPC: A23G3/32
Filed: 1988-09-26
Abstract: PURPOSE:To obtain a high-purity caramel at a low cost by discharging high- voltage current in a stock liquid produced by adding sulfuric acid to a liquid of a carbohydrate of e.g., sweet potato and contacting the super-heat of the generated park flame in vacuum, thereby converting the semilose and cellulose in the stock liquid into caramel. CONSTITUTION:An electric current of >200V is passed through a hydrated liquid containing semilose and cellulose in a carbohydrate of sweet potato, beet, etc., as a caramel raw material to effect the electric discharge in a liquid. The heat of the spark flame generated by a liquid-spark apparatus for the above treatment is directly contacted to the stock liquid by the vacuum contact action without leaving a space between the flame and the stock liquid. The polymer compounds comprising the semilose and cellulose in the stock liquid are quickly converted into caramel by the asymmetric carbonization action to obtain the objective caramel without generating solid carbonaceous material.

Title: Static pressure gas bearing device
Inventor: YAMAZAKI SHIZUKA
IPC: F16C32/06
Filed: 1994-10-05
Abstract: PURPOSE:To prevent the air hammer, and improve the rigidity of a bearing by mounting a magnetic member on either of a rotary member and a bearing member through a clearance from the other member, and keeping the magnetic fluid in the clearance in contact with the magnetic member and the other member with the magnetic flux between the magnetic member and the other member. CONSTITUTION:A plurality of rows of gas reservoirs 6 are provided on the outer diameter surface of a bearing sleeve 4 at an equal space in the circumferential direction, and when the compressed gas is fed from a gas feeding passage 9 to a gas feeding port 7, the compressed gas flows from the gas reservoirs 6 to a bearing clearance 5, supporting a rotary shaft 1 by a housing in a non-contact manner. A magnetic member 10 consists of a permanent magnet 11 and two yokes 12 made of ferromagnetic material, and the magnetic fluid 14 in the clearance between the yokes 12 and the housing 3 is kept by a magnetic circuit consisting of the permanent magnet 11, the yokes 12 and the housing 3. The vibration of the rotary shaft 1 can be damped by supporting the rotary shaft 1 by the housing 3 through the magnetic fluid 14 because the viscosity of the magnetic fluid 14 is large compared with that of the gas. Thus, no air hammer is generated even when the gas reservoir 6 are increased in size, and the quality and the working condition of the porous material can be easily controlled.

Title: Structure of exhaust gas turbine supercharger
Inventor: IMAKIRE KOICHIRO
IPC: F02B39/14
Filed: 1985-10-30
Abstract: PURPOSE:To operate a supercharger safely and smoothly by dividing a lubricating line from a contained lubricant head tank, into a main line for feeding oil in the high rotational speed range just after occurrence of the state of emergency stop, and an auxiliary line for cooling for feeding oil after the rotational speed has been reduced. CONSTITUTION:Air in a contained lubricant head tank 3 is exhausted through an air vent line 2 when lubricant is fed from an inlet pipe 1. And the lubricant is fully filled in the head tank 3 causing the inside pressure to the built up. Resultantly, the lubricant flows through a main lubricating line 4 in the head tank 3 so as to be fed to each of bearings 6 and 7 on the thrust and anti-thrust sides, and each of journals 8 and 9 on the blower and turbine sides. In this case, after the oil level in the head tank 3 has been reduced below the upper end of the main lubricating line 4, the lubricant is fed to the journal bearing 9 on the turbine side through an auxiliary lubricating line 5. This protects the journal bearing 9 on the turbine side even when a supercharger is suspended because of emergency.
