Title: Manufacture of arsenious acid
Inventor: OODO SHIYUUICHI
IPC: C01G28/00
Filed: 1983-01-11
Abstract: PURPOSE:To control the concn. of antimony in a soln. contg. arsenic to a very low level when the soln. contg. arsenic obtd. by reacting an aqueous soln. contg. copper sulfate with a precipitate contg. arsenic sulfide is reduced to recover arsenious acid, by specifying the concn. of copper in the soln. contg. arsenic. CONSTITUTION:An aqueous soln. contg. copper sulfate is reacted with a precipitate contg. arsenic sulfide at about 70-90 deg.C with stirring so that the resulting slurry has about 10-15% concn. and the slurry is subjected to solid-liq. separation to obtain copper sulfide and a soln. contg. arsenic. Copper in the soln. contg. arsenic is removed until the concn. of copper in the soln. is lowered to <=3g/l. A reducing agent such as a gas contg. SO2 is added to the purified soln. contg. arsenic to reduce quinquevalent arsenic present in the soln. to tervalent arsenic. The reduced soln. contg. arsenic is concentrated by heating or other method, it is cooled to crystallize arsenious acid, and solid-liq. separation is carried out to recover the arsenious acid of high purity. The concn. of antimony in the arsenious acid is very low.

Title: Data transfer equipment
Inventor: IMAI HIROYUKI
IPC: H04L12/28
Filed: 1989-01-06
Abstract: PURPOSE:To prevent a data from being transferred to a network other than a required transfer route by providing a storage circuit storing an address of a communication equipment belonging directly to a high-order network and a low-order network and a storage circuit storing an address of the communication equipment belonging indirectly to the low-order network. CONSTITUTION:A data received from the low-order network is transferred to a data transfer circuit 3, and a routine control circuit 4 retrieves whether or not an address exists in a 2nd storage circuit 6 storing the address of a communication equipment connecting directly to the low-order network and in a 3rd storage circuit 7 storing the address of the communication equipment connecting indirectly to the low-order network. When the address exists in the 2nd storage circuit 7 or the 3rd storage circuit 7, the received data is aborted. If the address does not exist in the 2nd storage circuit 7 or the 3rd storage circuit 7 conversely, the received data is transferred to the high-order network via a 1st medium control circuit 1.

Abstract: PURPOSE:To prevent a vessel from deforming or peeling on sterilizing treatment of a retort, by fixing air-tight at least all the outer periphery of the thin-walled inner vessel to the outer vessel under a pressurized condition after the thin- walled inner vessel is arranged in the outer vessel. CONSTITUTION:At first, an outer vessel 10 is made of extruded polypropylene. And to be different from the outer vessel, a complex film is molded by a press molding method or the like to produce a thin-walled inner vessel 20. Next, these outer vessel 10 and the thin-walled inner vessel 20 are combined together to superimpose with each other at the flanges 11, 21 and contained in a depressed device and then the depressing device is deaerated more than 100mm Hg to make the pressure within the device less than 600mm Hg.
