Title: Production of fine iron oxide
Inventor: NAKAJIMA SUSUMU
IPC: C01G49/06
Filed: 1985-11-15
Abstract: PURPOSE:To obtain ferric oxide grain wherein the grain size is uniform and fine by heating the aq. soln. of ferrous sulfate heptahydrate at transition temp. or above changed into ferrous sulfate monohydrate to form crystal of ferrous sulfate monohydrate and drying the separated crystal and roasting directly it. CONSTITUTION:Water is added as a medium to ferrous sulfate heptahydrate and the formed aq. soln. is heated at the temp. within the range of 64 deg.C-100 deg.C transition temp. changed into ferrous sulfate monohydrate and dehydrated. Thereby after forming ferrous sulfate crystal having water of crystallization close to monohydrate, this crystal and the above-mentioned aq. soln. are separated at 64-100 deg.C temp. The aimed ferric oxide grain is obtained by drying the separated crystal by air blasting at <=200 deg.C temp. and roasting directly this dried crystal at 650-900 deg.C temp. By this invention, the solidification and the clogging of a device are not caused in case of heating ferrous sulfate heptahydrate and dehydrating it.

IPC: B65D81/26
Filed: 1989-09-29
Abstract: PURPOSE:To obviate the need to undergo a vacuum process, make can material thinner than the one employed in the current high vacuum can, shorten the expelling time of oxygen due to the evolution of carbon dioxide and make the use of deoxidizing agent unnecessary by providing a metal can with a one- way operating valve for escaping carbon dioxide. CONSTITUTION:A small through hole 5 is formed in the bottom lid 4 of a metal can at one place thereof and closed with a one-way operation valve 6 for escaping gas fixed to the inner plate surface of the bottom lid 4. Roughly ground coffee beans are filled in the can through a lower opening of a can body 1 with a can lid 3 fixed thereto and the bottom lid 4 is joined with the lower opening of the can body 1 in a double seam manner, while a gas in the can is being replaced with an innert gas, whereby the ground coffee beans are sealed in the can. When the carbon dioxide evolving from the coffee beans sealed in the can rises in pressure, it passes from a hole 6c of a perforated plate 6a into an air hole 6g to press a diaphragm plate 6e covering the air hole 6g so as to produce between the diaphragm 6e and its valve seat surface a gap, through which the carbon dioxide is allowed to flow and discharged from the can through the hole 5.

IPC: H04N1/00
Filed: 1990-09-27
Abstract: PURPOSE:To enable demand/command communication with a computer even during a head search processing by executing the head search processing of a read paper sheet according to a dividing system. CONSTITUTION:When the read paper sheet is inserted, a paper detection sensor detects the read paper sheet and the operation moves to the head search processing. The head search processing of the read paper sheet is divided into the prescribed number of processes and successively executed in arithmetic cycle. Namely, since the head search processing of the read paper sheet is executed by the dividing system, after one divided process is executed, the operation returns to the execution of a main process, and the next divided process is executed in the next arithmetic cycle. Thus, the data/command communication with the computer is enabled even during the head search processing of the read paper sheet.

Filed: 1989-09-29
Abstract: PURPOSE:To detect in real time the end of a road by inputting the traveling direction of a mobile vehicle as the substantial main scanning direction of a raster scan system and the front image of the vehicle as the serial picture signals respectively. CONSTITUTION:A camera 1 scans data by a raster scan system and takes out a data train. Thus the main scanning direction is coincident with the traveling direction of a mobile vehicle. A bright and stable density signal is obtained within a road area from the multi-level picture signal undergone the main scan in the traveling direction of the vehicle. At the same time, a density signal having high density and a large fluctuation is obtained in an area out of the road. A comparator 3 compares the density value d0 of the head picture element latched by an initial value memory 2 with the density value dx of the subsequent picture signal. Then din showing an area within the road is outputted to a frame memory 6 when ¦d0-dx¦<epsilon is satisfied and a counter energizing signal (= 1) is outputted to a counter 4. Meanwhile dout showing an area out of the road is outputted together with a counter energizing signal (= 0) when ¦d0-dx¦>=epsilon is satisfied respectively. The output of the counter 4 shows the road end address of each line of a picture element.
