Title: Temperature detecting circuit
Inventor: KURIHARA SHINJI
IPC: G11B7/126
Filed: 1994-03-31
Abstract: PURPOSE:To obtain a temperature detecting circuit, which is not affected with the voltage of a power supply, by providing a resistor, which is connected to the anode of a diode whose cathode is grounded, a resistor, whose one end is grounded, and the like. CONSTITUTION:A first resistor 8 is connected to the anode of a diode 7, whose cathode is grounded. One end of a second resistor 9 is grounded. The voltages, which are obtained by subtracting the base-emitter voltages from the bias voltages, are generated at the emitters of first and second transistors 10 and 11. Therefore, specified voltages are applied on the diode 7 and the resistors 8 and 9. Thus, the specified voltages are generated at the emitters of third and fourth transistors 12 and 13 by currents flowing through the resistors 8 and 9 and applied on the bases of fifth and sixth transistors 14 and 15. The emitter voltages of the transistors 14 and 15 are applied on the bases of seventh and eighth transistors 16 and 17. Furthermore, voltages, which are lower than the base voltages by specified voltages, are generated at the emitters of the transistors 16 and 17. Therefore, the output in correspondence with the change in temperature, which does not comply with the change in voltage of a power supply, is generated.

Title: Distributing type fuel injection pump
Inventor: NAGANUMA TAKAO
IPC: F02M41/14
Filed: 1995-03-23
Abstract: PURPOSE: To provide a distributing type fuel injection pump which provides more constant and stable fuel injection amount. CONSTITUTION: A distribution passage 16 which communicates with each cylinder of an internal combustion engine is formed in a cylinder 6. A distribution port 26 is formed by a first groove 261 which is extended in the peripheral direction of a distribution rotor 13 in the distribution rotor 13 which rotates in the cylinder 6. The shape of a bottom face 261a of the first groove 261 is circular arc which has the center on an axis of the distribution rotor 13. When the distribution rotor 13 rotates, the distribution port 26 is communicated with the distribution passage 16, and fuel which is pressurized by a plunger is fed under pressure from the distribution port 26 to the distribution passage 16.  Although the peripheral direction position of the distribution port 26 which is communicated with the distribution passage 16 when fuel is fed under pressure differs depending on timer position, the fluctuation of discharge passage area during the communication of the distribution port 26 with the distribution passage 16 is small because the bottom face 261a of the first groove 261 is formed into the circular arc shape, and constant and stable fuel injection amount can be obtained.
