Title: Production of long-chain alkyl halides
Inventor: SUGIYAMA MASAHIDE
IPC: B01J27/08
Filed: 1993-08-09
Abstract: PURPOSE:To obtain the subject compounds in high yield with hardly any occurrence of the transfer of an alkyl group in a long-chain alcohol by reacting the long-chain alcohol as a raw material with benzal chloride in the presence of a Lewis acid. CONSTITUTION:This method for producing long-chain alkyl halides is to react a benzal chloride expressed by formula I [X is a halogen or a lower alkyl; (n) is 0-2] with a long-chain alcohol expressed by formula II (R is a 5-10C straight-chain alkyl) in the presence of a Lewis acid which is a catalyst, substitute OH in the long-chain alcohol with the halogen while producing hydrogen chloride and afford the corresponding long-chain alkyl halide. For example, n-pentanol, n-hexanol or n-heptanol is cited as the long-chain straight-chain alcohol and, e.g. p-chlorobenzal chloride or p-methylbenzal chloride is cited as the benzal chloride. For example, a Lewis acid such as aluminum chloride, ferric chloride or zinc chloride is cited as the catalyst. The long-chain alkyl halides are useful as an intermediate for agrochemicals, medicines, dyes, etc.

Title: Automatic level adjusting circuit
Inventor: IZAWA KAORU
IPC: H03G3/30
Filed: 1982-12-14
Abstract: PURPOSE:To realize the direct coupling of a signal transmitting section by controlling the level of an input signal when a DC level of an input signal exceeds a reference level. CONSTITUTION:A voltage comparison circuit 66 compares the reference level with a value of an output signal of an amplifier 52 and generates a pulse having a width corresponding to the section of an input signal level higher than the reference voltage level. This pulse turns on a transistor (TR) 72. A capacitor 76 is charged by a current flowing to the TR72. A variable resistive element 58 is controlled by a terminal voltage of the capacitor 76. The input signal is attenuated corresponding to a value where the peak value of an inputted AC signal exceeds the reference voltage. Since no coupling capacitor is used for the controlling part, the circuit integration is attained easily.
