IPC: H04B7/15
Filed: 1985-10-17
Abstract: PURPOSE:To attain miniaturization and low power consumption by using a comparator circuit to generate a supervisory gate signal thereby applying initial setting of an optional value in one frame through the designation of a supervised value and an initial value. CONSTITUTION:A supervisory gate signal 18 is opened by a pulse 13 at the end of frame of a ground control address counter 1 and set by an output pulse 17 of a comparator circuit 3, and the pulse 17 is outputted when an output signal of the counter 1 and the supervised value 16 are coincident.

Filed: 1992-09-01
Abstract: PURPOSE:To obtain an N-vinylformamide composition, containing formic acid in the N-vinylformamide, excellent in preservation stability and useful as a raw material for polymerizable monomers. CONSTITUTION:The composition is obtained by including 1-250pm formic acid and further, as necessary, 10-10000ppm antioxidant (e.g. 2,6-di-t-butyl-p-cresol) in N-vinylformamide. This composition is preferably preserved in a hermetically sealed container at <=30 deg.C in an inert gas atmosphere so as to maintain the formic acid content of the N-vinylformamide at <=250ppm. The increase in the content of the formic acid causing cationic polymerization can be suppressed by specifying the content of the formic acid and further adding the specific antioxidant thereto. As a result, the deterioration in both the purity of the N-vinylformamide and the polymerization activity during the preservation for a long period can be suppressed.

Filed: 1996-09-04
Abstract: PROBLEM TO BE SOLVED: To dissolve torque step difference generated at the time of starting to drive supercharger by increasing the opening of a throttle valve at the time of connecting a clutch. SOLUTION: A control unit 14 controls the continuation of an electromagnetic clutch 29 and the opening of a by-pass flow regulating valve 7.

The temperature of intake air flowing into a cylinder is thereby heightened to accelerate warm-up of an engine 1. At the cut-off time of switching the electromagnetic clutch 29 from on to off, in case of making the opening of the throttle valve 9 constant, driving torque to a supercharger 4 is temporarily reduced, and engine torque is increased.  Coping with this, the opening of the throttle valve 9 is increased to suppress the collapse of engine torque.
