Title: Production of carboxylic acid
Inventor: NAKANO TATSUYA
IPC: C07C53/124
Filed: 1992-10-30
Abstract: PURPOSE:To efficiently obtain a highly pure carboxylic acid from the product of Koch reaction using sulfuric acid catalyst. CONSTITUTION:An olefin such as propene or an alcohol such as 2-propanol is reacted with carbon monoxide in the presence of sulfuric acid catalyst, and a carboxylic acid such as isobutyric acid is extracted with a solvent such as decane having a solubility parameter of <=8.5(cal/cc)<0.5> from the mixture containing the sulfuric acid and the produced carboxylic acid. The carboxylic acid can also be obtained by extracting the mixed solution with a solvent having a higher boiling point than that of the carboxylic acid and subsequently distilling the extract solution. The carboxylic acid can further be recovered by extracting the mixture with an organic solvent and subsequently treating the extract solution with a weakly basic anion exchange resin.

Title: Paper feeding mechanism
Inventor: NAGANO KIYOSHI
IPC: B65H3/06
Filed: 1995-11-10
Abstract: PROBLEM TO BE SOLVED: To eliminate a feed roller heretofore used to stabilize the travel of paper and convey paper with accuracy only by a picking roller. SOLUTION: Paper feeding mechanism is composed of a sensor arm 3 for detecting the skew feed of paper 1, a picking roller 10 that can correct the conveyed direction of the paper 1, and a link arm 4 for transmitting the motion of the sensor arm 10 to the picking roller 10. When the paper 1 is fed skew in a direction B, the right end of the paper 1 pushes a rising part 3b of the sensor arm 3. The sensor arm 3 thereby moves in the direction of an arrow mark B. At the same time, a cam 6 also moves in the direction of the arrow mark B, and the cam face of the cam 6 pushes the link arm 4 in the direction of an arrow mark D, so that a bearing part 4a of the link arm 4 pushes a rotary shaft 2 of the picking roller 10 in the direction of the arrow mark D.  The rotary shaft 2 is therefore rotated in the direction of an arrow mark E around a fulcrum 8, and the direction of the picking roller 10 is changed in a reverse direction to the skew direction (B-direction) of the paper 1, so that the skew feed of the paper 1 is corrected.

Inventor: FUJIOKA KIYOSHI
IPC: G07F9/00
Filed: 1990-11-26
Abstract: PURPOSE:To make the repairing work of a commodity delivering device easier and improve the workability of the work by forcibly generating a bridge by means of a bridge generating pin when a commodity housing section is full of commodities. CONSTITUTION:When a commodity housing section 19 is full of commodities (cans), a bridge generating pin 95 is inserted into the section 19 from a pin inserting hole 93 and a bridge is forcibly generated among the cans. Since the cans forming the bridge support each other and a supporting force which is balanced to the weight of the cans is produced due to the bridge and a static balance is maintained among the cans forming the bridge even when the supporting force by the cans below the bridge disappears, a commodity delivering device 53 can be taken out of the section 19 after taking out the cans below the bridge. Therefore, the device 53 can be repaired quickly even when the device 52 becomes out of order.
