IPC: C07C15/24
Filed: 1987-12-24
Abstract: PURPOSE:To obtain the aimed substance, by treating a raw material oil containing an isomeric mixture of dimethylnaphthalene with a zeolite adsorbent, treating the absorbed substance with a desorbing agent to provide a solution containing the 2,6-isomer in a specific concentration or above and the desorbing agent and subjecting the resultant solution to crystallization treatment in a specific concentration of the desorbing agent. CONSTITUTION:A raw material oil containing an isomeric mixture of dimethylnaphthalene is treated with an adsorbent (e.g., Y type zeolite containing Li on cationic sites) and then with a desorbing agent consisting essentially of p-xylene and/or o-xylene to provide a solution containing a mixture containing >=60wt.% 2,6-isomer and the desorbing agent. Crystallization treatment is then carried out at 40-90wt.% concentration of the desorbing agent in the solution to afford the aimed substance. The crystallization treatment is performed by cooling the solution or evaporating the desorbing agent. The high-purity 2,6-isomer is obtained in high yield by the aforementioned method.

Title: Controller for internal combustion engine
Inventor: NAKAZAWA SHINSUKE
IPC: F02D29/00
Filed: 1989-12-18
Abstract: PURPOSE:To prevent an engine stall from occurring by controlling a fuel cut and recovery timing so as to be delayed when clutch engagement has been detected, and when clutch disengagement has been detected the other way, controlling the fuel cut and the recovery timing so as to be hastened. CONSTITUTION:A fuel cut and recovery timing control means A hastens a fuel cut and recovery timing when disengagement of a clutch C is detected by a clutch operating state detecting means B and an engine brake is in a state of being unworked. Therefore engine speed will not go down earlier at all and, what is more, any delay for fuel supply will not occur, thus any engine stall is prevented from occurring. In addition, since the means A controls the fuel cut and recovery timing so as to be delayed at time of engagement of the clutch C, such a fear that fuel might be recovered earlier is brought to nothing, thus fuel consumption is improved.

Abstract: PURPOSE:To unnecessitate a waveform equalizer circuit and an envelope line detection circuit, to miniaturize a circuit and to reduce a cost by connecting a differentiation circuit to a comparator and forming a window gate circuit by using the output signal of the differentiation circuit. CONSTITUTION:An analog reproducing signal A is differentiated by the differention circuit 11 to output a signal C. The signal C is sliced with zero volt by a zero intersection detection circuit 12, and the signal D allowing a mark position to be a fall edge is outputted to a gate circuit 13. At this time, a noise in the vicinity of zero volt is outputted, as well. On the other hand, the signal C inputted to the comparator circuit 14 is compared with a slice level H with a voltage value V+, and a signal amplitude exceeding the value is made to be a mark and a high level is outputted for the period, and the amplitude not exceeding the value is made as a noise and the low level signal I is obtained. The signal I is delayed by a delay circuit 15 so that the signal D becomes the intermediate in the high level period of the signal I, and the signal J is obtained. The signal J is ANDed with the signal D by the circuit 13. In such a manner, a binarization signal G is obtained by eliminating the noise excepting the mark position.
