Title: Stabilizing method for recovered oxidation catalyst
Inventor: IGARI MASAHIRO
IPC: C01G51/06
Filed: 1979-10-08
Abstract: PURPOSE: To stabilize catalyst used in the manufacture of terephthalic acid, by addition of inorg. acid and/or org. acid to the carbonate of Co and Mn catalyst, which has been recovered by addition of CO 3   2-  to a soln. obtained by dissolving calcined reaction residue formed in the manufacture of terephthalic acid in sulfuric acid after the soln. is neutralized and separated from precipitate.  
     CONSTITUTION: Reaction mixture formed in the oxidation of p-xylene in acetic acid in the presence of Co and Mn catalyst is separated from acetic acid and terephthalic acid. To the calcined material of the concentrate of residual reaction mother liquor is added sulfuric acid in order to dissolve 95% or more of Co and Mn. The sulfuric acid soln. is neutralized with alkali such as Na 2 CO 3  so as to remove impurities such as iron, chromium, copper etc. by precipitaion. To the soln. of Co and Mn hereby obtained is added CO 3   2-  such as alkali carbonate to precipitate the carbonate of Co and Mn, which is recovered by separation. Inorg. acid (e.g. HBr) and/or org. acid (e.g. oxalic acid) in quantity ≥0.001pt.wt. preferably ≥0.01pt.wt. is added to 1pt.wt. recovered Co and Mn carbonate thereby producing stable Co and Mn carbonate which causes no change in quality.

Title: Ribbon take-up apparatus
Inventor: SATO KAZUHIKO
IPC: B41J33/22
Filed: 1986-06-06
Abstract: PURPOSE:To facilitate the taking-up of a ribbon and to prevent the slackening thereof, by providing ratchet-like connection parts having phase difference due to the difference in the number of teeth. CONSTITUTION:The rotational difference between a take-up reel 1 and a transmission gear 2 is absorbed by the slip of the ratchet-like parts between the transmission gear 2 and a take-up reel shaft 3. Said parts are different in the number of teeth and generate phase difference. Therefore, by forming the transmission gear from a material excellent in elasticity, the tooth form part of the transmission gear 2 comes into continuous contact with the tooth form of the ratchet-like part provided to the take-up reel shaft 3 at a certain pitch and, therefore, the pulasation of the transmission torque thereof can be made min. as compared with such a case that the number of teeth of the transmission gear 2 are same to those of the take-up reel shaft 3. A take-up reel spring 4 presses the transmission gear 2 to the take-up reel shaft 3 and transmits the power of the take-up reel shaft 3 to the cap 5 of the take-up reel shaft 3. Said pulsation is prevented by a ratchet structure using positional difference and, further, power is transmitted through the spring and, therefore, no pulsation exerting effect on printing is generated.

CONSTITUTION:Plural conductive layers 2-2'' are formed on a base plate 1 and arranged insulatedly from each other. Current is supplied to the voltage application terminals (a)-(c) of the layer 2-2'' and electrodeposition is carried out from a soln. obtained by dispersing an electrodepositable polymer and a dye hardly soluble or not soluble in water, onto the layer 2-2'' to selectively form colored layers 3-3''. Then, these operations are repeated by using other dyes to form the colored layers 3'-3'', and the terminals (b) or (c) is connected with at least a part of (a) or (b) to feed current and form the colored layers 3-3''. Voltage is applied to the terminals (a)-(c) in the order of execution of each color deposition. Current is drawn from the terminals (a)-(c) by using a conductive rubber, and the terminals necessary to form the colored layers and those of the already deposited layers are coated with a conductive paste to feed current. At that time, electrodeposition is not repeated on the deposited layer. As a result, pattern slip is not caused and dyeing prevention treatment is not necessary.

Title: Structure of optical head
Inventor: NISHIKUMA HIROAKI
IPC: G02B7/28
Filed: 1989-05-25
Abstract: PURPOSE:To improve the sensitivity of detection and to improve the non-linearity of a detecting characteristic by providing first and second photodetectors being mutually adjacently provided, in a photoreceiving body, composing the first photodetector of a band-shaped area including the axial core of an optical axis in detecting light and specifying the width of the band-shaped area. CONSTITUTION:A first photodetector 13 is composed of the band-shaped area including the axial core of the optical axis in the detecting light and the width of the band- shaped area is gradually increased from an end part toward a central position corresponding to the axial core. In such a case, since both photoreceiving bodies 13 and 16 are arranged in mutually symmetric positions to the focal point of the detecting light, the spot size of the detecting light is reversely changed on each photoreceiving body in correspondence to the change of a focusing error. Then, since respective detecting values are mutually compensated, a result being obtained by subtracting one detecting value from the other detecting value, is comparatively widely changed to the change in the size of the spot in the detecting light and the sensitivity of the detection can be improved. Then, by making the shape of the first photodetector 13 suitable, the non-linearity of the detecting characteristic can be improved.
