Title: Device for purifying and recovering acetic ester
Inventor: HIRAO MASASHI
IPC: B01D53/04
Filed: 1985-06-05
Abstract: PURPOSE:To obtain a purified acetic ester, by treating the acetic ester containing acetic acid collected by active carbon adsorption process with potassium carbonate or sodium carbonate, and removing effectively and efficiently acetic acid. CONSTITUTION:A raw material gas is pretreated by the pretreating device 101, introduced to the adsorption tank 103, a solvent component is adsorbed on active carbon and collected, and the collected solvent component is desorbed with steam. The distillate solution is condensed and liquefied by the condenser 104, and separated into a solvent phase and an aqueous phase by the separator 105. The solvent phase is sent to the catalytic deacidifying column 111, brought into contact with potassium carbonate or sodium carbonate from the circulating line J in counter current, so acetic acid contained in the solvent phase is converted into K salt or Na salt. The deacidifying solvent stored in the middle tank 113 is dehydrated by the dehydrating distillation column 108, purified by the purifying column 114 so K salt and Na salt are removed to give a purified acetic ester. The aqueous phase separated by the separator 105 is sent to the dehydrating column 106, the solvent component contained in the aqueous phase is recovered and returned to the separator.

Filed: 1985-06-04
Abstract: PURPOSE:To sharply improve the long-term heat-resisting property of the titled permanent magnet by a method wherein a precipitation hardening R2TM17 type alloy which undergoes an oxidation-preventing surface treatment is used as magnetic powder, and thermoplastic resin polyphenylene sulphite is used as a resin binder. CONSTITUTION:After thermally stable and oxidation-preventing surface processed precipitation hardening R2TM17 type magnetic powder and thermoplastic resin polyphenylene sulphite are heat-molten and kneaded, they are molded in a magnetic field. The resin polyphenylene sulphite has a high melting point of 285 deg.C, and its kneading and molding temperature is 320-340 deg.C. As a result, the above-mentioned TM17 alloy, which has excellent thermal stability and is hardly oxidized, is used. A surface treatment is performed on the TM17 alloy for the purpose of preventing oxidation, and besides, it is desirable that the kneading and molding operation are performed in N2 or inert gas atmosphere in order to suppress the deterioration of efficiency by oxidation.

Abstract: PROBLEM TO BE SOLVED: To suppress the degradation of an image formation rotating member by providing a clutch mechanism stopping rotation of the image formation rotating member while a paper discharge roller is reversely rotated and recording paper is carried again to an image forming part by a sub-carrier path. SOLUTION: A clutch gear is a one-way clutch which rotates when a reversible motor is normally rotated and does not transmit driving force of the reversible motor when the reversible motor is reversely rotated. A second driving force transmitting part normally rotates an image formation roller group (a photosensitive drum 8, a fixing roller 12) and a main carrier path roller group (a resist roller 17) when the reversible motor is normally rotated and stops these rotations when the reversible motor is reversely rotated. A control part rotates a paper carrier switching lever 18 in an A direction, reversely rotates the reversible motor, reversely rotates a paper discharge roller 19 and normally rotates carrier rollers for sub-carrier path 20 to 22. Thereby, recording paper P is fed to a sub-carrier path and is carried toward the resist roller 17.

Abstract: PROBLEM TO BE SOLVED: To improve usability of a washing machine, which operates its lid closing means during the drain valve closing by measuring the open/close time of the drain valve, and informing a user that the lid is ready for opening based on the measuring time when the user attempts to open the lid. SOLUTION: When a drain valve 9 draining water in the outer drum of a washing machine is switched from 'open' to 'close', a control device 3 rotates a motor 94 as well as switches a switch 'close' 92 and a switch 'open' 93, and the switching status is detected by a drain valve status detector 31. At the same time, a time measuring device 32 start to operate, and when the switch 'close' 92 is switched from on to off, and the switch 'open' 93 is switched from off to on, the motor 94 stops and the open/close time of the drain valve is measured. When a user attempts to open the lid during dewatering by pushing an operation button, the motor 94 stops, a buzzer 4 informs a user that the lid is ready for opening based on the measured time, which eases the user.

Title: Optical fiber coupler and its manufacture
Inventor: SASAKI MASARU
IPC: G02B6/30
Filed: 1979-09-20
Abstract: PURPOSE:To make it possible to optically couple optical fibers with a thin-film light transmission line with efficiency by employing the constitution in which the core shape of the end part of optical fibers optically coupled with the rectangular flank of the thin-film light transmission line is gradually changed from a circle to an oval. CONSTITUTION:At both the sides of one end of optical fiber 3 to be optically coupled, reinforcing members of fixed length, i.e. glass guides 4 and 5 are bonded sandwiching. Glass guides 4 and 5 use a glass material that has softening temperature and a thermal expansion coefficient nearly equal to those of core glass 1 or clad glass 2 of optical fiber 3. Next, optical fiber 3 and bonded glass guides 4 and 5 are elongated being integrally heated in a heating method such as arc discharge so that the sgape of the part will nearly be circular. Then, fabricated fiber 6 is cut at its thinned part, whose cut section is flank-processed by polishing, chemical etching, etc. Thus the core shape of the end of optical fiber 6 is determined and core section 1' shown by fiber flank 7, i.e. the flank of optical fiber 6 in an oval shape can be obtained.

Title: Semiconductor device
Inventor: HORIGUCHI KATSUJI
IPC: H01L31/115
Filed: 1979-09-21
Abstract: PURPOSE:To obtain a semiconductor device which does not necessitate an external power supply by disposing a radioactive substance as an energy source and utilizing radioactive rays irradiated thereform. CONSTITUTION:A p type layer 10 and an n type layer 9 are formed on an n type substrate 11. When radioactive rays 15 are irradiated to the vicinity of a p-n junction, excessive electrons and holes are produced in the p type and n type layers by an ionization, are flowed into the n type and p type layers by the accelerating electric field of the junction, and a net current will flow from the n type layer to the p type layer. Since the junction area of the layers 11 and 10 is wider than that of the layers 9 and 10 and an electrode 12 is on the layer 9, the amount of the radioactive rays reaching the junction is less, and the recombination time of the layer 9 is longer than that of the layer 11. Accordingly a current will flow from the layer 11 to the layer 10. Since the junction between the layers 11 and 10 is formed normally in a depth of several mun, high energy alpha-particles or low energy beta-particles are adapted for use. According to this configuration power supply can be applied to the semiconductor device merely by coating radioactive substance on the surface of the semiconductor chip or containing case, but on wire is necessary at all.

Abstract: PURPOSE:To form an image on the full surface of an aperture in response to the size of a measuring point and improve S/N ratio by providing such a constitution as enlarging and contracting the effective area of a photoelectric surface for introducing the electrons released from the photoelectric surface to the aperture according to the magnitude of the exciting current to a focusing coil. CONSTITUTION:A mesh electrode 26 is disposed in a position adjacent to an aperture 16 side of a photoelectric surface 12 within a cylindrical sealed vessel 10, and a diode 28 forming a multiplying part is disposed between the aperture 16 and an anode electrode 14. When the exciting current of a focusing coil 22A on the side close to the photoelectric surface 12 is reduced and the exciting current of a focusing coil 22B is increased, the magnetic flux density becomes smaller on the photoelectric surface 12 side than on the aperture 16 side, the effective area of the photoelectric surface 12 for introducing the photoelectrons released from the photoelectric surface 12 to the aperture 15 is extended. When the quantities of the exciting currents are reversed, the effective area is reduced.
