Title: Method for obtaining acetic acid and methanol from methyl acetate
Inventor: TSURUMARU NAOMICHI
IPC: C07C27/00
Filed: 1982-08-25
Abstract: PURPOSE:To hydrolyze methyl ester of a carboxylic acid into a carboxylic acid and methanol, and recirculate and use the carboxylic acid for the acid exchange reaction, by subjecting methyl acetate and a carboxylic acid having a specific number of carbon atoms to the acid exchange to obtain the methyl ester of the carboxylic acid and acetic acid. CONSTITUTION:Methyl acetate is subjected to the acid exchange with a >=4C carboxylic acid in the presence of an acidic catalyst, preferably a strongly acidic type ion exchange resin. In the process, butyric acid is used as the above-mentioned carboxylic acid, and the acid exchange reaction is first carried out in the first reactor 6 to introduce the resultant effluent into the first distillation column 7. An azeotropic mixture of the methyl acetate with water, etc. is circulated from the top of the first distillation column 7 through the first reactor 6, and methyl butyrate, etc. is introduced from the bottom of the column 7 into the second distrillation column 8. An azeotropic mixture of the methyl butyrate with water is introduced from the top of the second distillation column 8 into the second reactor 10 and passed through the bottom to the third distillation column 9 to give the acetic acid from the top of the third distillation column 9. The hydrolysis reaction is carried out in the second reactor 10 to give methanol from the top of the fourth distillation column 11, and an organic layer from a decanter 12 is distilled in the fifth distillation column 13 to circulate the resultant butyric acid from the bottom of the fifth distillation column 13.

IPC: H02K29/10
Filed: 1977-12-09
Abstract: PURPOSE:To simplify the structure and facilitate the maintenance, by applying or cutting off the current of a stator winding depending on the periodical variation in the inductance of the stator winding due to the rotation of the magnetic poles of a stator. CONSTITUTION:A magnetic circuit is composed of the stator magnetic pole 1 having the stator winding 3 centering a power shaft 5, and a rotor magnetic pole 2, which rotates together with the power shaft 5. For example, the rotor magnetic pole 2 is rotated by human power on a pedal 4 etc. At such an angle that the inducance of the stator winding 3 starts rising from the minimum (when the projection of the rotor magnetic pole 2 faces the intermediate place between the projections of the stator magnetic poles 1), a phototransistor 3 provided on the winding 3 is turned on by light received through a slit 9 opened in the rotor magnetic pole plate 2. Thereby, electrical current is supplied to the stator winding 3 to attract the rotor magnetic pole 2 in the direction of the rotation. The electrical current is cut off at an angle just before the inductance becomes maximum.

Title: Synchronizing separating circuit
Inventor: HOSOYA NOBUKAZU
IPC: H04N5/08
Filed: 1981-09-18
Abstract: PURPOSE:To sufficiently separate vertical synchronizing signals, by setting the separating sensitivity of the amplification separating stage to a low level, and by changing over the separating sensitivity in such a way that it becomes higher  when the composite video signal becomes a vertical synchronizing signal. CONSTITUTION:Composite video signals passed through a filter installed at the outside are introduced to a amplitude separating stage 1 through a pin (1). A frequency separating stage 2 integrates horizontal and vertical synchronizing signals obtained at the collector of a transistor T172 with a circuit composed of transistors T173-T175, etc. Vertical synchronizing signals are separated by comparing the output signal from the circuit with a fixed voltage at a circuit composed of transistors T179-T181. Pulses corresponding to the period of the vertical synchronizing signal are impressed upon a transistor T177, and a collector current I2 of a transistor T178 is increased by the pulse. Accordingly, gains of the integrating circuit ocmposed of the transistors T173-T175 are enlarged, and thus, the vertical synchronizing signal can be separated sufficiently.

Filed: 1989-06-12
Abstract: PURPOSE:To reduce the program capacity of a controller and simultaneously to improve the maintenance properties of a printer by providing a host interface (switching means), a printing switch (print-out means), etc. CONSTITUTION:A CPU of an engine driver 40 is driven when a printing switch 90 on the driver 40 is turned on and a print-out request is received for the maintenance information stored in the driver 40. A CPU 4 converts each maintenance information stored in a nonvolatile memory 70 into a data format similar to that defined when a host computer 20 sends the picture information to a controller 30. Then the converted maintenance information is sent to the controller 30 via a communication cable 200 and a host interface 60. The controller 30 converts the received information into the picture signals that can be printed by a printer and sends these picture signals to the driver 40. The driver 40 actuates the printer to print out the respective pieces of maintenance information. Consequently, the program capacity of the controller 30 can be reduced and simultaneously the maintenance properties of the printer can be improved.

Filed: 1981-09-22
Abstract: PURPOSE:To obtain a thin beltlike brazing filler metal for diffusion bonding that can bond a base metal easily with high accuracy, by melting two kinds of brazing filler metals of different melting point separately and projecting onto the surface of a rotating body from a group of nozzles arranged in parallel alternately, and cooling them. CONSTITUTION:Materials 13, 13' of brazing filler metals of different melting point are put in containers 11, 11' separately and melted. Gas pressure is applied to the molten brazing filler metals 13, 13' and the metals ae projected onto the rotating face of a rotating body 16 from nozzles 14a, 14'a-14c, 14'c arranged in parallel alternately. Thin flakes of projected brazing filler metals come into contact at their sides and are quenched, and a body of brazing filler metal in which thin belts are connected alternately in the direction of width is obtained continuously. When the brazing filler metal 17 is used for diffusion bonding of base metals, the base metals do not move freely as the two brazing filler metals do not melt simultaneously. Accordingly, the base metals can be bonded at high accuracy without using a plunger punch.
