Title: Synthesis of beta-alkyl-substituted naphthalenes in liquid phase
Inventor: IIZUKA TOKIO
IPC: C07B61/00
Filed: 1988-06-27
Abstract: PURPOSE:To industrially advantageously produce the subject compound by alkylating a naphthalene compound with an olefin in the presence of a solid ultrastrong acid catalyst in a liquid state, further adding the naphthalene compound to the reaction product and subsequently subjecting the mixture to a transalkylation reaction on the same catalyst. CONSTITUTION:A naphthalene compound is subjected to a liquid phase alkylation reaction using an olefin in the presence of a solid ultrastrong acid which has a high catalytic activity, has no corrosive property against reaction apparatus and is readily separated. The product is again mixed with the naphthalene and then subjected to a transalkylation reaction on the same catalyst to provide a beta-alkyl-substituted naphthalene. The method permits the selective synthesis of the objective compound under a mild condition and in a short time. The method further permits the easy separation of the catalyst and the ready taking-out of the reaction product and does not require any specific installation. The objective compound is useful as an intermediate raw material for drugs, dyes, agricultural chemicals, synthetic resins, etc.

Title: Method of rapid stopping of reversible pump-turbine
Inventor: KUWABARA HISAO
IPC: F03B15/18
Filed: 1979-12-10
Abstract: PURPOSE: To close a guide vane safely when abnormal reverse rotation of a driving motor is caused during pump operation of a reversible pump-turbine, by detecting reversing of water flow, and switching the speed pattern for rapid closing of the guide vane to a slower speed pattern when the reverse water flow is detected.  
     CONSTITUTION: Abnormal reverse rotation of a driving motor, caused during pump operation of a reversible pump-turbine, is detected through detection of reverse water flow. Here, arrangement is such that a speed pattern PP for rapid closing of the guide vane, to be applied for the pump operation mode of the pump-turbine, is switched automatically to a slower speed pattern PT for rapid closing of the guide vane, to be applied for the turbine operatiom mode. By employing such an arrangement, it is enabled to prevent occurrence of abnormal rise of pressure in a pressure pipe at the time of closing the guide vane and therefore to close the guide vane safely when abnormal reverse rotation of the driving motor is caused during pump operation of the reversible pump-turbine.

Title: Copying machine
Inventor: TAKAYA KAZUYASU
IPC: G03G21/00
Filed: 1978-12-26
Abstract: PURPOSE: To enable the discharging of transfer paper in the state when no images are formed thereon by erasing the electrostatic latent images on photosensitive drum with an interimage erasing lamp when original clogging occurs in the automatic original feed mechanism.  
     CONSTITUTION: If original clogging occurs, the original 20 stagnates in the position of an original detecting sensor 30 even when a fixed time elapses after energizing of a solenoid 29 and therefore an original clogging detection circuit 33 outputs the original clogging signal R 2 . The signal R 2  is sent to an interimage erasing lamp control circuit 35, which in turn outputs the control signal R 3  to an interimage erasing lamp 5 to keep lighting the erasing lamp 5, thereby radiating the entire surface of the photosensitive drum 2 and erasing its electrostatic latnet images. Becuase of this, transfer paper 11 is discharged in a white state into a paper discharge tray 16. Here, in the case of mis-copying, an AND circuit 37 does not output the count signal R 5  and a counter 38 does not make count operation and therefore it is not counted as copying sheet number.
