摘要:
A method for continuously producing a liquid low molecular weight polymer of conjugated diolefin having a number average molecular weight of 300 to 10000. The method comprises the step of continuously polymerizing or copolymerizing conjugated diolefin in an inert hydrocarbon solvent at a temperature of 40.degree. to 70.degree. C. with maintaining the quantity of dissolved oxygen in the reaction system at 1 ppm or below and in the presence of a polymerization catalyst of an organic sodium compound and a chain transfer agent of an alkylaryl compound.

A display control system for a scan type display apparatus in which a display screen is divided into a plurality of split display regions on a video screen and each display region is scanned in parallel. A dual port memory having a random access port and a serial access port is used as a display memory and display data is inputted through the random access port and outputted through the serial access port. Display addresses for reading out sequentially display data corresponding to each raster of every split display region one by one from the dual port memory are generated and the display data of each of the split display regions read out from the dual port memory are stored into each of the buffer memories. The display data stored in the buffer memories is read out and transferred to the scan type display device.
摘要:
A vacuum source device of vacuum booster is disclosed. The device includes an air ejector having an air inlet communicated with the atmosphere, an air outlet connected to a vacuum pick-up port opening to the portion of the intake system of an internal combustion engine downstream of a throttle valve, and a pressure reduction chamber connected to a vacuum chamber of the vacuum booster. A by-pass passage connecting between the vacuum pick-up port and the vacuum chamber of the vacuum booster by detouring the diffuser of the air ejector imposes a smaller flow resistance than the diffuser. A first check valve is disposed in the by-pass passage, while a second check valve is disposed between the by-pass passage and the vacuum chamber.

A hair growth method includes repeatedly washing hair using a washing agent that includes a microbubble washing composition and microbubbles, the microbubble washing composition including a protease and a lipase. The hair growth method exhibits an excellent hair growth effect.
摘要:
A tandem-type vacuum booster having a partition plate providing front and rear chambers with a booster piston and diaphragm in each chamber. A piston boss is slidably supported on the partition plate and a connecting cylinder is formed on the front chamber booster piston. A press plate is provided on the piston boss and the rear booster piston and an end plate of the connecting cylinder are coupled to the piston boss by the press plate and a plurality of bolts disposed around the piston boss with the rear booster piston and diaphragm clamped between the press plate and piston boss. The front ends of the bolts are disposed to come closer to the piston boss axis than the rear ends. The bolt heads are also received in recesses provided in the press plate to prevent relative rotation between the bolts and press plate.
摘要:
In a method for purifying a crude epoxidation product of a liquid conjugated diolefin polymer or a vegetable oil which comprises the steps of adding an aqueous washing agent to a crude epoxidation product which is obtained by the reaction of a liquid conjugated diolefin polymer or a vegetable oil with an organic peracid or an epoxidizing agent capable of generating an organic peracid in situ, stirring the mixture, leaving the mixture to stand to induce phase separation and thereafter withdrawing the organic layer, the improvement wherein 50 to 300 parts by weight, per 100 parts by weight of the crude epoxidation product, of a 10-80% by weight aqueous solution of isopropanol is used as the washing agent.

摘要:
A method for producing B-type crystals of nateglinide substantially free of H-type crystals is provided, which comprises drying solvated wet crystals of nateglinide at a low temperature until no solvent remains and making a crystal conversion thereof. According to this method, B-type crystals of nateglinide can be produced at an industrial scale without allowing other forms of the crystalline polymorphism to coexist.
