Filed: 1989-01-20
Abstract: PURPOSE:To prevent the increase of a loss and the increase of a load impedance based on the increase of a load current by controlling a base voltage according to a voltage value between the base emitter of a control transistor (TR). CONSTITUTION:A protective circuit connects one edge of a detecting resistor R5 to the emitter of a control TR Q1, connects the emitter of a detecting TR Q5 to the other edge of the resistor R5, and connects the base of the TR Q5 to the base of the TR Q1.

Abstract: PURPOSE: To improve output performance and low-pollutant property of the engine by inserting switches operating correspondingly to the change in the operational condition of a vehicle into the electrification circuits of respective electromagnetic valves controlling a back-flow quantity controlling valve and a fuel-quantity increasing valve.  
     CONSTITUTION: When the engine E is operated by putting on an ignition switch 44, the electromagnetic valves 12 and 22 are electrified at the same time when the 1st vehicle operational condition detecting switch Ss1, an air pressure detecting switch Sa and the 1st engine temperature detecting switch St1 are turned ON or when the 2nd negative-pressure detecting switch Sv2, the air pressure detecting switch Sa and the switch St1 are turned ON. As the result, the electromagnetic valve 12 is operated and thereby the valve body 7 of the fuel-quantity increasing valve 6 is opened with its negative-pressure chamber being opened to the air, whereby the quantity of fuel is increased. When a by-pass channel 52 is communicated with an opened-to-air port 35 by electrification of the electromagnetic valve 22, air bypasses a suborifice 42 2 , the channel therefor is restricted only to the main orifice  42 1  and thus the back-flow ratio of exhaust is increased.

Abstract: PURPOSE:To enable a sensor to be compact by providing two current-detection circuits for detecting each load current of two current-measurement pulse-supply circuits which supply charging current to a capacity to be measured in the case of one level of a pulse for measurement and discharge in the other level. CONSTITUTION:Transistors Q11 and Q12 alternately repeat ON and OFF, current when the Q11 is ON is a transient current for charging a capacity C1 of a fixed electrode P1 of a sensor 4 and a total CS1, and an amount of electric charge is equal to an amount of electric charge which is discharged from the total CS1. A current of a power supply terminal VD1 is output from a current circuit 5 and at the same time a current from a power supply terminal VD2 is output to a comparison circuit 7 from a current circuit 6, thus enabling a differential current between drive circuits 1 and 2 to flow to a load resistor R. A voltage corresponding the differential current is generated between an output terminal 0 and a bias power supply B. The differential current can be known by measuring this voltage and a stable operation can be achieved even if the sensor is miniaturized.

Abstract: PROBLEM TO BE SOLVED: To decrease a deformation amount of a cabin with respect to a shock applied to the front of a box car by providing a forward slit in an insertion hole. SOLUTION: At an upper surface member of a bracket 4, a slit 42 and an opening are formed which are formed in the forward direction so as to be communicated with an outer circumferential end of the bracket 4 and in a shape so as to enable insertion of a shaft part 61 of a fastening bolt 6. With the constitution, when a shock is applied to the front of a vehicle body 1, the shaft part 61 of the bolt 6 connecting a sub frame 3 to a cabin 5 is slipped out of the opening along the slit 42 of the bracket 4. Then, the bracket 4 and a cabin side connection part are brought into a disengaged state and thereby the sub frame 3 is separated from the cabin 5 easily. Accordingly, even if front ends of a side frame 2 and the sub frame 3 are crushed and recessed, a base end part of a front piller 7 does not follow it, thereby reducing generation of a forward inclination deviation.
