Title: Constant speed running device for automobile
Inventor: TANIGAWA MITSUARI
IPC: F02D41/14
Filed: 1979-02-02
Abstract: PURPOSE: To raise reliability and to make automobile compact and light-weighing by a system wherein, in case an actuator responding to the engine negative pressure controls a throttle link system, the output duty is laid on the input speed formula through an integral circuit to perform, spark time advancing control compensation.  
     CONSTITUTION: The constant running device consists of a closed loop making a round of a controllor, actuator, accelerator link, engine, vehicle and speed sensor. Thereby the controllor has an F/V conversion circuit 20, which converts the frequency of the speed signal detected by the speed sensor into the voltage corresponding to the ripple containing speed, and a memory circuit 24, which memorizes the speed-corresponding voltage while running through the constant running setting operation. From these circuits 20, 24, the difference voltage is sought for in the comparative circuit 21 to be so constituted as to put this in the spark time advancing compensation circuit 25. The output of this timing compensation circuit 25 is fed into the actuator through the gate 29 to operate throttling system utilizing the negative pressure.

IPC: G05F1/56
Filed: 1989-01-20
Abstract: PURPOSE:To interrupt or automatically reactivate a current flowing through an auxiliary power source circuit, to reduce heat generation, and to miniaturize an auxiliary power source circuit by using two positive characteristic thermistors and thyristors. CONSTITUTION:Generally a lost power source quantity is expressed by an expression of 'a current X a voltage X a time.' An inputted current is applied through a resistance 2 and a positive characteristic thermistor 11, heat energy is generated on the both parts, and the both temperatures of the resistance 2 and the positive characteristic thermister 11 are increased. At such a time, the thermistor 11 increases its resistance value due to its positive characteristic. When the resistance value is increased to a certain extent, a voltage drop is increased, the voltage on the anode side of a diode 6 becomes smaller, and a control circuit 9 stops its operation at a point A. When the resistance value further increases, and the gate voltage of a thyristor 13 increases, the thyrister 13 is made into a conductive state at a point B, and the control circuit 9 can be operated again.

Abstract: PROBLEM TO BE SOLVED: To prevent the development of uneven thickness caused by disturbance of metal flow and obtain a hollow extrusion shape material having uniform quality by forming the billet pressing surface of a die for extruding as a recessed conical surface. SOLUTION: The die 3 for extruding the hollow extrusion product forms the recessed conical surface 20 to the pressing surface 30 for the billet. An angle forming the conical surface 20 with the plane 21 crossing at the right angle to the die 3 axial line, i.e., a die angle θ is desirable to set to 5-15 deg.. Further, the conical surface 20 is desirable to be formed so that a projected area to the plane 21 crossing at the right angle to the die 3 axial line becomes 50-100% of a projected area to the plane 21 of the whole pressing surface 3a for the billet in the die 3. Both metal flows 2a, 2b form laminated flows having the orientation and centripetal property toward a die hole 11 and do not collide by forming this conical surface 20.  Therefore, the disturbance in the metal flows 2a, 2b is not developed and the hollow extrusion shape material 10 having uniform thickness size can be extruded.
