Title: Production of tar acid
Inventor: CHINEN EITATSU
IPC: C07C27/00
Filed: 1983-05-16
Abstract: PURPOSE:To prevent sulfur compounds, particularly thiols from distilling away and obtain tar acid without containing impurities, by dehydrating crude tar acid obtained from a tar based oil, adding an oxidizing agent to the resultant dehydrated tar acid before distillation, and distilling the resultant tar acid. CONSTITUTION:A tar based oil is extracted with an alkali to give a tar acid salt, which is then decomposed with an acidic substance to afford crude tar acid. An oxidizing agent is added to the crude tar acid before the distillation thereof. The resultant tar acid is then distilled within <200 deg.C bottom temperature range in a continuous or batchwise vacuum distillation apparatus to give a purified tar acid. The distillation of the crude tar acid is carried out in an initial distillation column or phenol column, etc., and the above-mentioned oxidizing agent may be added to the dehydrated tar acid to be charged into the initial distillation column or added to the overhead distillate of the initial distillation column. Hydrogen peroxide, etc. is preferred for the oxidizing agent, and the amout thereof to be added to the dehydrated tar acid is preferably 1,000-2,000ppm usually as a solution.

Title: Paper transfer control device of duplicating machine
Inventor: KUDO KUNIO
IPC: B26D7/18
Filed: 1986-04-14
Abstract: PURPOSE:To prevent displacement of a copied image and to prevent skew or wrinkle of a copying paper sheet from being produced by increasing transfer speed of the copying paper sheet in a paper feed part by means of a tail end signal of an original immediately before cutting. CONSTITUTION:A servomotor 11 with a frequency generator drives feed roller pairs 2, 3 and 5 while a servomotor 12 drives a resistance roller 6, a photosensitive drum 7 and a transfer part 10. Based on a tip detection signal S1 from an original, a signal generating device 15 outputs rotation command signals of a same speed to both drive control devices 13 and 14. Then, based on an original tail end detection signal S2, the signal generating device 15 is made to output a rotation command signal prior to a cut signal to increase the speed of a paper feed side roller only. This produces slack in a buffer area between roller pairs 5 and 6 to prevent a copied image from being displaced at the time of cutting action with a cutter device 3. Namely, since the slack of a copying paper is produced just before the cutter action, transfer of the copying paper is stabilized and wrinkles, etc. are unlikely to be produced.

     CONSTITUTION: When a circulating heat medium receives heat in a heat collector 1, a solvent is separated in a gas-liquid separator 2 as vapor and liquified in a liquifier 3 before being led into a heat accumulator 5 or heat generator 11. On the other hand, the dissolved substance solid body in the gas-liquid separator 2, whose liquid level has lowered and whose temperature has been raised becuase the solvent has been separated therefrom, gathers in a solid-liquid separator 4. Said conditions are sensed by means of a sensor, and a valve 7 is opened according to the instructions therefrom. Consequently, the dissolved substance solid is dropped into the heat accumulator 5. Then, by means of a pump P, the liquid in the heat medium chamber provided to the heat accumulator 5 is delivered to the gas-liquid separator 2 for replenishment. By said constitution, the circulative use of the heat medium is made possible, the quantity of accumulated heat is increased, and the heat transfer efficiency can be improved.

Title: Driving device
Inventor: TAKAO NOBUHIRO

Filed: 1997-04-03
Abstract: PROBLEM TO BE SOLVED: To improve the workability of winding, by controlling rotational control in response to the place of a moving piece after the start of a motor, and eliminating the need for a multicore signal conductor for a positional signal. SOLUTION: Since positional signals (b) detected by a position detecting means 26 on a motor 21 side are overlapped onto the driving power of a power line 23 for driving a motor through a coupling means 27, each overlapped positional signal (b) is reproduced by a positional-signal reproducing means 29 on the driver 22 side and a motor driving means 33 drives the motor 21 by motor-driving outputs (d) corresponding to the reproduced positional signals (e), a rotational-speed range capable of controlling rotational driving in response to the places of a moving piece 24 is not limited as the conventional case of the formation of the positional signals by back electromotive force. Since no conventional multicore signal conductor for the positional signals is required, the wiring works of the signal conductors are removed and the workability can be improved largely.
