Title: Semiconductor device for igniting internal combustion engine
Inventor: FURUHATA SHOICHI
IPC: F02P3/04
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To suppress the oscillation of collector voltage and reduce the value of collector voltage becoming a constant value in a current limiting area in the case where an IGBT is used as a semiconductor device for ignition. Which is used for an igniter ignition circuit. SOLUTION: In the case where the collector voltage is higher than the gate voltage while current is being limited, an increase in the collector voltage directly after the start of current limiting increases the voltage of a gate terminal by using a constant current circuit 4 comprising a high voltage resistant constant current element 2 and a low voltage resistant constant current element 3 connected in series for a circuit wherein voltage is applied between a collector terminal and a gate terminal when micro current flows from the collector terminal to the gate terminal. Then, an increase in the gate voltage suppresses a sudden increase in collector voltage. In addition, when collector voltage is lowered by oscillation, an action to increase gate voltage from the collector terminal is eased, suppressing the lowering of collector voltage.  In addition, collector current is suppressed by the low pressure resistant constant current element 2, reducing the generation loss of an IGBT.

Abstract: PROBLEM TO BE SOLVED: To reduce driving loss and improve specific fuel consumption of a reciprocating engine suitable for airplanes that fly in high airspace for a long time by individually controlling a waste gate valve and a bleed valve of a supercharger at each stage. SOLUTION: A multistage supercharge system 100 has three stages of superchargers, i.e., a high pressure stage supercharger 30, a medium pressure stage supercharger 40, and a low pressure stage supercharger 50. A waste gate valve W (W1 to W3) and a bleed valve B (B1 to B3) are provided in respective superchargers. A pressure sensor P (P1 to P3) is provided in the outlet side of a compressor of the supercharger. Based on signals from the respective sensors, a control means controls each of the valves W and B individually. For instance, if a pressure value read in the pressure sensor P in one stage has reached the predetermined value for the stage, the control means controls so that the valves W and B in this stage are closed and a turbine and the compressor in the stage are operated.

Abstract: PURPOSE:To provide a device at a low cost by providing a transmitting and receiving part in a master device, applying a transmission right only to one slave device, allowing the other slave device to operate only reception, allowing one slave device having the transmission right to control the other slave device, and executing inter- slave device speech. CONSTITUTION:When a user operates a slave device A9, a transmission right abandonment signal is transmitted to a master device 2. Then, when the master device 2 receives the signal, and transmits a connecting instruction signal to the both slave devices again, the transmission claim is moved from the slave device A9 to a slave device B15. At that time, the transmission output of the slave devices A9 is stopped, the transmission output of the slave device B15 is started, and the transmission of a signal from the slave device B15 can be attained. Next, when the user operates the slave device B15, and abandons the transmission right the transmission right is moved from the slave device B15 to the slave device A9 in the above mentioned procedure. This operation is repeated so that the inter-slave device communication of a semi-duplex system can be attained. Afterwards, when the slave device having the transmission right transmits an on-hook signal to the master device 2, the master device 2 transmits a restoring instruction signal to the both slave devices, so that the waiting state of the both slave decices can be restored.

Since all sensors 81, 82, 91, 92, 93 are in an OFF state at the point of finish of the automatic positioning, an XY direction can be moved in the direction of sensor center in view from sensors in an ON state. Atheta direction is divided into the side of a clockwise direction and one of a counterclockwise direction against a line joining the center of a sensor part 5 to the center of a side in the side whereon two or more sensors exist and rotated to the side of rotation direction whereon many sensors are in an OFF state with the center of the center of the sensor part 5 as a rotation center. The IC is moved in the X, Y, theta directions determined as above. When an output and state of sensors vary, directions are determined again and moved.
