Title: Balanced/unbalanced impedance conversion circuit
Inventor: KIYONO HIDEKI
IPC: H03H11/32
Filed: 1988-04-27
Abstract: PURPOSE:To obtain a conversion circuit whose frequency characteristic is excellent at a wide range with small size by constituting the circuit by a differential amplifier and resistors. CONSTITUTION:Resistors R1 to R3 of a matching distribution circuit are selected as required and the impedance when viewed from the input terminal of a balanced/unbalanced impedance conversion circuit 10 is made equal to the impedance of the connected cable. Each output via the resistors R2, R3 is processed by a differential amplifier 11 being a noninverting circuit of the same phase and a resistor R8, and a differential amplifier 12 of an inverting circuit of opposite phase and a resistor R9, and the impedance is halved to the output impedance depending on the resistance of the resistors R8, R9. Since no transformer is required, the unbalanced/balanced impedance conversion circuit whose frequency characteristic is excellent over a wide band is obtained with small size.

Title: Production of cyclopentanone
Inventor: OGURI MOTOHIRO
IPC: C07C45/00
Filed: 1991-04-11
Abstract: PURPOSE:To produce cyclopentadiene by reacting cyclopentene with water in an inert gas atmosphere using a catalyst consisting of a Pd compound and a copper compound or an iron compound, thereby preventing the deactivation of Pd and easily separating the catalyst. CONSTITUTION:Cyclopentanone is produced in one step by reacting cyclopentene with water in an inert gas atmosphere (e.g. nitrogen atmosphere) in the presence of a catalyst consisting of a Pd compound and a copper compound or an iron compound (e.g. a combination of palladium chloride and cupric chloride). The process is advantageous from industrial viewpoint since cyclopentanone can be produced in high selectivity without depositing palladium mirror in the reaction step. Cyclopentanone is a compound extremely useful in industrial field as an intermediate for polymeric compounds (e.g. nylon and polyester), plasticizer and synthetic lubricant and as a solvent. The process does not cause the deactivation of expensive Pd and produces the product in a state easily separable from the catalyst. The used aqueous-solution of the catalyst can be regenerated and reused.
