Filed: 1988-09-14
Abstract: PURPOSE:To obtain high measurement accuracy and reliability by eliminating the discharging of the variable capacity type capacitor consisting of floating electrostatic capacity formed with the ground which is affected by an external electric field. CONSTITUTION:The integration output V0 of an integrating circuit 12 has potential distributions to series-connected capacitors CA and CB through a buffer amplifier 13 as shown by equations I and II. When the terminal voltage VB across the capacitor CB does not reach the threshold voltage VR of a DC power source, the series-connected capacitors CA and CB are provided with the polarity for raising the output voltage V0, i.e. negative feedback, so that the V0 is stabilized on condition that VB = VR.

The ruled table is regarded as a series of a multiplicity of rectangles connected to each other, and the ruled table is formed by setting the multiplicity of frames (rectangles). The coordinate storing part 44 stores the coordinates of the frames expressed in Q numbers. In the case of a process requiring calculations of coordinates, such as a movement, elongation or contraction of the ruled table, the coordinates in Q numbers stored in the storing part 44 are converted into coordinates in inches, then a moving quantity or an elongating or contracting quantity is calculated in inches, the results of calculation are converted into values in Q numbers, and the values in Q numbers are stored. By this, it is possible to obviate the generation of cumulative errors which are generated in the case of performing the calculations in Q numbers.

Accompanied with the contraction, the needle 8 is moved and is inserted longer into the piping resistance variable part 7, so that the piping resistance is increased. While at the time when temperature is lower than the set value, the thermally responding element 9 exposed to the air passage 5 is lengthened. The needle 8 is moved being accompanied with the elongation, and the inserted part of the needle 8 into the piping resistance variable part 7 becomes shorter, so that the piping resistance is decreased. The rate of feed oil is increased by the decrease of piping resistance. The moving distance of a neelde 8 is designed so that the feed liquid fuel and the combustion air can get the optimum ratio.

Title: Signal branching coupler
Inventor: AOKI EIJI
IPC: H04Q3/42
Filed: 1988-09-19
Abstract: PURPOSE:To improve S/N by interrupting the transmission of a branching facing signal branched from a facing line at the time of a branching self-signal and interrupting the folded transmission of the branching self-signal at the time of a branching facing signal, by a transmission control circuit. CONSTITUTION:A first transmission control circuit 55, at the time of a branching self-signal, opens a contact rl11 and interrupts the transmission of a branching facing signal and at the time of a branching facing signal, opens a contact rl12 and interrupts the folded transmission of a branching self-signal.
