Title: Method for separating acrylic acid
Inventor: KAWASAKI KYOSUKE
IPC: C07C57/07
Filed: 1994-08-23
Abstract: PURPOSE: To readily and efficiently separate acrylic acid from an aqueous solution of a crude acrylic acid obtained by cooling a gas produced by carrying out catalytic oxidation of propylene and/or acrolein with molecular oxygen and/or absorbing the gas into water. CONSTITUTION: This method for separating acrylic acid comprises substantially distiling water, acetic acid and a solvent away from a tower top in one azeotropic distillation tower and recovering acrylic acid substantially free from water, the solvent and acetic acid from the tower bottom by refluxing a solvent obtained by subjecting a distillate from the tower top to oil-water separation to tower top and circulating the distillate into the feed position of the crude acrylic acid water solution and/or in the lower part than the feed position in a method for separating acrylic acid by cooling a gas produced by subjecting propylene and/or acrolein to catalytic oxidation with molecular oxygen and/or absorbing the gas into water, feeding the resultant crude acrylic acid water solution to an azeotropic distillation tower,  distilling the acrylic acid using a solvent forming an azeotrope together with each of acetic acid and water as an azeotropic solvent.

Title: Magnetic drive circuit
Inventor: ISHINAGA HIROYUKI
IPC: H01F7/18
Filed: 1985-09-10
Abstract: PURPOSE:To raise the return speed of a wire, by a method wherein a magnetic field is generated by flowing current to a coil and just after driving the material to be driven, the reverse current is passed to the coil. CONSTITUTION:By bypassing the coil 5 connected onto the collector side of a transistor 13, a diode 15 and a capacitor 14 are in series connected and the midway between both is earthed via a capacitor 16. The current from a certain time to its stop flows in a loop state like the arrow mark of sign 17 and electric charges are stored in the capacitor 14. When this loop current stops to flow, the capacitor 14 starts to discharge electricity and passes current reversely to the coil 5 like an arrow mark 18. The eddy current of magnetic circuit and the magnetic flux due to residual magnetism are quickly reduced by this reverse current. Thereby, the time until the wire returns to the original position is shortened and the return speed of wire can be improved.

Title: Truncating apparatus for electronic musical instrument
Inventor: HAYAKAWA TOKUJI
IPC: G10H1/18
Filed: 1987-08-08
Abstract: PURPOSE: To generate a playing sound with fine harmony by preferentially erasing a discord having a small degree of harmony and leaving a consonance having a high degree of harmony at the time of assigning a channel to new tone level information. CONSTITUTION: An upper keyboard(UK) 12, a lower keyboard(LK) 14, a switch group 16, a central processing unit(CPU) 18, a program memory 20, a register group 22, a table memory 24, a tone generator(TG) 26, etc., are connected to a bus 10. When new tone level information is generated during the use of all musical sound generation channels, the degree of harmony of a melody sound with chords is checked in each channel to which the melody sound e.g. is assigned. A melody sound having a small degree of harmony is preferentially erased against a melody sound having a high degree of harmony to assign a channel to the new tone level information. Consequently a playing sound with fine harmony can be generated.

Title: Data converter
Inventor: ASAGI NAOMI
IPC: G06F12/00
Filed: 1998-07-14
Abstract: PROBLEM TO BE SOLVED: To improve the operation efficiency of data conversion in a data converter for converting data at receiving and delivering of data between different CADs(computer-aided design). SOLUTION: A parameter storing means 1 stores in advance a parameter for converting data between various kinds of CADs. When an operation means 5 gives a reading instruction, a parameter reading means 2 reads a parameter optimum for data conversion of CAD into receive/deliver from the means 1. This read optimum parameter is displayed on a monitor 4 by a parameter display means 3. An operator confirms the parameter on the monitor 4 and gives a data converting instruction, if the contents are satisfactory. Thus, according to the parameter displayed on the monitor 4, a data conversion means 6 converts the CAD data.

Title: Engine member of non-metallic inorganic material
Inventor: SUGANO NOBUYUKI
IPC: F02B75/02
Filed: 1981-12-10
Abstract: PURPOSE:To prevent the fuel leakage and the dropping of the inorganic material while lowering the engine noise, by constructing the engine member such as a block body with non-metallic inorganic material such as concrete or ceramic then forming a thin film layer of resin onto the surface.

Title: Manufacture of amorphous semiconductor solar cell
Inventor: HAMA TOSHIO
IPC: H01L31/20
Filed: 1985-09-09
Abstract: PURPOSE:To make a transparent conductive film of the pinhole part into a high resistance one by laser beam irradiation by detecting the pinhole part after forming an amorphous semiconductor thin film on an insulating transparent substrate through the transparent conductive film as an electrode on one side. CONSTITUTION:An SnO2 film 2 as a transparent electrode is vapor-deposited on a glass substrate 1 and an a-Si thin film 3 is formed on the SnO2 film 2. Over this a-Si film 3, monochromatic light is projected to detect a pinhole 5. Next, the substrate 1 on which the a-Si thin film has been formed is put in hydrogen atmosphere and is irradiated with the laser beams from a YAG laser 6. Then, the reduction of SnO2 due to hydrogen proceeds to produce SnO and a sheet resistance of the transparent conductive film in the part 7 increases. As the resistance in the part 7 where the metal put in the pinhole 5 (51: bottom of the pinhole) comes in contact with the transparent conductive film 2 is high even if an electrode film 4 is formed on the a-Si thin film 3 by, e.g., vapor deposition, the decline of the characteristics due to electric short can be prevented.

Abstract: PURPOSE:To ensure the low voltage alarm operation of a system section and the backup of reception information by detecting that a battery voltage is dropped to any of three stages of prescribed voltages so as to control the alarming operation, the operation of the system section and the stop of the operation of all the functions of the system section. CONSTITUTION:When a 1st detection circuit 14 detects that the voltage of a battery 13 is dropped up to the low voltage alarm starting voltage of a system section 11 receiving an individual selective signal from a base station and displaying the signal or the like, the low voltage alarm operation of the system section 11 is activated in response to a detection output 14a. Moreover, when a 2nd detection circuit 15 detects that the voltage is dropped up to the backup start voltage of reception information, the system section 11 is activated in the backup mode and when a 3rd detection circuit 16 detects that the battery voltage is dropped up to the reset starting voltage, all the functions of the system section 11 are stopped. Thus, the backup of the reception information is ensured during the low voltage alarming of the system section.

IPC: G06T9/00
Filed: 1983-10-25
Abstract: PURPOSE:To eliminate the need for a frame memory of large capacity and a high speed code converter by constituting an MH code of a code to be decoded in real time. CONSTITUTION:One page's share of MH coded data such as document or picture stored in a file storage device 1 is reproduced and stored in a read buffer 2 comprising an RAM. After a register 3 is reset in order to read one word of MH codes from a series of MH code strings in which the boundary is not clear, logical 1 is set to the left end bit only and MH code word data for one page's share stored in the buffer 2 are read one by one bit until a code word end signal is generated in a code word end detection circuit 12. One word of the read MH code is fed to an ROM4 as an address signal. Since a decoded data is stored in the ROM4, when the address signal is a complete MH code, the length of the white or black picture line to be decoded is obtained in a binary number.

Title: Method and device for joining ends of wire rods or bars
Inventor: SATO RYUTARO
IPC: B23K3/04
Filed: 1992-07-27
Abstract: PURPOSE:To prevent the generation of dust without increasing extra man-hours such as grinding work when the ends of mild steel welding wires are joined together. CONSTITUTION:The welding wire end joining device 1 is provided with a brazing filler metal reel 4 to supply beltlike brazing filter metal between a couple of energizing clamps 2 and 3.
