IPC: C07C27/02
Filed: 1983-02-25
Abstract: PURPOSE:To prepare the titled substance with little production of the condensation by product, by reacting xylylenediamine with a nitrous acid salt in the presence of a lower aliphatic carboxylic acid and water to obtain a mixture of the titled substance and its mono- and dicarboxylic acid ester, and hydrolyzing the ester. CONSTITUTION:Xylylenediamine is made to react with a nitrous acid salt (e.g. sodium nitrite) in the presence of a lower aliphatic carboxylic acid (preferably acetic acid) and water at 60-100 deg.C to obtain a mixture of the titled substance and its mono- and dicarboxylic acid esters. The carboxylic acid is neutralized by adding an alkaline aqueous solution to the mixture, and the mixture is made alkaline with an alkali, hydrolyzed at 60-80 deg.C under agitation, and treated with an organic solvent to extract the objective substance. The extraction residue composed mainly of sodium acetate is added with concentrated sulfuric acid to regenerate acetic acid at <=25 deg.C, and the acetic acid is recycled to the reaction system. EFFECT:The use of a large amount of acetic acid is not necessary, and the amount of waste water can be reduced. USE:A raw material of polyurethane, etc. or a modifier.

Title: Driving mechanism of tape recorder
Inventor: HIRAHISAI KATSUYA
IPC: G11B15/44
Filed: 1980-03-11
Abstract: PURPOSE:To ensure a constant-speed forwarding, fast forwarding, rewinding and others of a tape and then realize a small size for the driving mechanism of a tape recorder, by biasing the 4th rotor to the left or right according to the rotating direction of the 3rd rotor and thus securing a selective engagement for the 4th rotor with the 1st or 2nd rotor. CONSTITUTION:With a high-speed rotation of the motor 31 in the forward direction, the center pulley 16 and the gear 19 are also turned in the same direction. The gear 25 has a reverse rotation in the direction of the arrow B. As a result, a rotary bias force is applied to the switch driving plate 21 to secure an engagement between the gears 15 and 25 on the reel drive disk 13, and thus the disk 13 is turned toward the arrow C to give a fast forwarding to the tape. When the motor 31 has a high-speed rotation backward (toward the arrow D), both the pulley 16 and the gear 19 are also turned in the same direction. And the gear 25 turns toward the arrow E. As a result, the plate 21 is biased in turning to secure an engagement between the gear 25 and the gear 14 on the reel drive disk 12. Thus the disk 12 is driven toward the arrow F to perform a tape rewinding action.

Title: Image forming device
Inventor: KOSHIMIZU YOSHIYUKI
IPC: G03G15/20
Filed: 1990-02-09
Abstract: PURPOSE:To prevent an end part from being defective in fixation and broken and to preclude such a phenomenon that approach control is impossible when a film is an endless belt by inhibiting the film from moving at the time of jam processing at a fixation part. CONSTITUTION:Even if a user performs jam processing in case of a jam, a drive path to a driving roller 17 is not reset. A fixed film 16, on the other hand, is tensed sufficiently by a tension spring 29 and has a sufficient frictional force with the driving roller 17, so the film move together with the driving roller 17 in one body. Consequently, even if jamming paper and the fixed film 16 are in a sticking state, the jamming paper can be removed without rotating the fixed film 16. Therefore, the fixed film 16 never deviates from a normal position range during the jam processing. Consequently, the film end part is prevented from being defective in fixation and broken and the approach control is prevented from being disabled when the film is endless.

Title: Improvement with respect to noise reduction
Inventor: CHARLES A BAUDOUIN
IPC: G06T5/20
Filed: 1997-01-07
Abstract: PROBLEM TO BE SOLVED: To provide a noise reduction system in which image quality is not deteriorated. SOLUTION: The edge emphasis noise reduction(EENR) system is an instantaneous compander system of the frequency characteristics. The system is applied to both chrominance and luminance encoders, and this system is best placed after a horizontal and vertical down sampling filters of the pre-processing stage of the encoders. The amplitude of high frequency low level information (mainly noise) is much reduced. Especially in the case of the EENR, it is designed to store detailed parts of the edge. Then a vertical cyclic filter is used so that the low level vertical information is not eliminated by the system. This filter is partially useful for a luminance circuit. A high level high frequency components are not almost affected. The systems passes low frequency information as it is.  The EENR is so designed to be active in relation to the MPEG coding of a source where there is slight noise and a transmission bit rate is limited. Moreover, the system is designed to minimize the loss of the image quality by the noise reduction process itself. It is not required to provide a complementary process to the receiver.

Inventor: KUWABARA TSUNEO
IPC: G02B6/44
Filed: 1988-02-13
Abstract: PURPOSE:To shorten a water stop distance and make a water stop effect excellent for a long time by uniformly distributing the powder or the particles of water absorbing resin without microbial decomposition between the fibers of a long-fiber nonwoven fabric sheet so as to be filled and fixed. CONSTITUTION:Water stop tape 1 for a cable is formed by means of that the powder or the particles of water absorbing resin 3 without microbial decomposition are distributed uniformly between the fibers 2 of a long-fiber nonwoven fabric sheet so as to be filled and fixed. Also, some of the powder and the particles are exposed on the surface and the rear face of the sheet. With this arrangement, when water enters the cable, the powder or the particles of water absorbing resin absorb water so as to swell in a moment and the water is stopped at only the place in the vicinity of water entering so that the water does not run in the longitudinal direction and the inside direction of the cable. Further, it is not decomposed by microorganisms, and thereby it exhibits an extremely excellent water stop effect for a long time.
