Title: Purification of isopropenyl acetate
Inventor: KAMEI NOBORU
IPC: C07C67/54
Filed: 1986-12-24
Abstract: PURPOSE:To easily improve purity of the titled compound in the distillation purification of the reaction product of acetone and ketene, without causing discoloration with time, by completely evaporating and removing high-boiling components from the reaction liquid under atmospheric or reduced pressure before distillation. CONSTITUTION:Acetone is made to react with ketene at >=50 deg.C preferably using naphthalenedisulfonic acid as a catalyst. The resultant reaction liquid containing isopropenyl acetate is neutralized. After the neutralization process, the pressure is reduced to extract volatile components and the evaporated liquid is distilled to obtain the objective compound. The distillation is carried out by using a perforated tray tower with >=20 stages under atmospheric or reduced pressure at a reflux ratio of about 2-3 in the case of bath distillation. In the case of continuous distillation, unreacted acetone is removed in the 1st column and isopropenyl acetate is distilled out in the 2nd column. The number of stages of the 1st and the 2nd columns are >=20 stages and the reflux ratio of each column is selected within the range of 2-5.

Filed: 1993-12-10
Abstract: PURPOSE:To well operate a deodorization mechanism by installing a dust filter on the upstream side of the deodorization mechanism in the duct of a waste disposal tank for stirring and drying waste and forcedly exhausting gas in the tank, and installing an adjoining dust receiver. CONSTITUTION:A garbage disposal tank 1 is formed of a rectangular chamber 2 for incubating a raw waste decomposition microorganism and an adjoining duct 3, and is fitted with a stirring vane 6 on the bottom part. Gas, including an odor generated in the chamber 2 in a decomposition treating process, is forcedly exhausted outside through the duct 3 from an opening 7 by the operation of a fan 8. The odor is chemically decomposed by contacting ozone generated by an ozone generater 10 to be deodorized. When gas, flowed into the duct 3 from the chamber 2 and having mixed dust blown up by the stirring vane 6, reaches the vicinity of a dust filter 12, flow velocity is reduced by ventilation resistance, and most dust is fallen to be accumulated in a dust receiver 13. Unfallen dust is caught by the dust filter to prevent the infiltration of dust into the ozone generater 10 or an ozone disposer 11.

Abstract: PURPOSE:To enhance chemical resistance of a thin film, by annealing a base body on which the thin film of various compds. is formed by a plasma CVD method in vacuum or under the existence of gaseous constitutional elements of the thin film at specified temp. CONSTITUTION:A base body 3 wherein the thin film of a compd. such as SiN, BN, SiO2 and AlN is formed on the surface by a plasma CVD method is fixed on a holder 2. Then the inside of a tubular reactor 4 made of quartz is exhausted via an exhaust pipe 9 of a chamber 1 made of metal adjacent thereto and regulated to about 10<-7>-10<-6>Torr degree of vacuum. In this state, the base body 3 is heated with a heater 5 such as an infrared ray lamp to anneal the thin film and hydrogen contained therein is removed. Besides in case the thin film is formed by SiN, BN and AlN, gaseous N2 is introduced into the tubular reactor 4 from a gas cylinder 6 to regulate the inside of the tubular reactor 4 to the atmopspheric pressure in a range within 760-10<-4>Torr. In case it is formed by SiO2, gaseous O2 is similarly introduced thereinto. Chemical resistance such as acid resistance and alkali resistance of the thin film is enhanced by annealing it to remove H2 contained therein.

Title: Vibration regulating material
Inventor: ABE TOSHIRO
IPC: F16F15/02
Filed: 1987-12-08
Abstract: PURPOSE:To obtain a vibration regulating material which is free from deformations or slippage even in a high-temperature ambience, by sticking soft foaming resin onto the opposite surfaces of a rubber material of high specific gravity type, and providing an adhesive material to one of the foaming resin surfaces. CONSTITUTION:Soft foaming resins 3a, 3b are sticked onto the opposite surfaces of a rubber material 2 of a high specific gravity type. An adhesive material 4 is provided on the surface of the one soft foaming resin 3b. Thus, a vibration regulating material 7 is obtained. For example, if the vibration regulating material 7 is wound around a piping 5 by the adhesive material 4 and secured by a bandage 6, the heat transmitted by the piping 5 is shut off by the soft foaming resin 3b and therefore difficult to be transmitted to the rubber material 2. The rubber material 2 increases the weight of the piping, so that a large vibration due to resonance is restricted. Moreover, even when the surface of the rubber material 2 is more or less softened by heat, the surface of the vibration regulating material 7 is kept elastic because of the soft foaming resin 3a, whereby the vibration regulating material 7 is easily bundled by the bandage 6. As described above, the vibration regulating material can be prevented from slipping or separating even in the use in a high temperature ambience. Furthermore, the vibration regulating effect of the material is not lost even in the use in a high temperature ambience. Accordingly, a breakage or deterioration of an apparatus by vibrations can be prevented by the present vibration regulating material.

Abstract: PURPOSE:To execute accurate exposure without deviation of exposure focus to a surface to be exposed having a projection part, a tilt end surface and a cylindrical surface, etc., by providing an optical fiber cable between the surfaces to be exposed of photomasks and making the optical fiber cable scan. CONSTITUTION:Light beams 15 passing through the photomask 12 are inputted in an input end part 14-1 in the optical fiber cable 14. After passing through the optical fiber cable 14, they are outputted from an output end part 14-2 and made to expose a substrate 13. Since the input end part 14-1 and the output end part 14-2 scan at the same speed at such a time, the pattern 11 of the photomask 12 is exposed and transferred on the substrate 13 on a position corresponding to said pattern. In such a case, the output end part 14-2 which scans the projection part 16 of the substrate 13 keeps a certain interval along the surface of the projection part 16 to accurately expose the pattern 11 on the projection part 16, so that the deviation of exposure focus does not occur. Thus, the exposure is accurately executed to the substrate 13 having the projection part 16.
