Title: Air-fuel ratio feedback control method for internal combustion engine
Inventor: FUJIMURA AKIRA
IPC: F02D41/00
Filed: 1986-04-28
Abstract: PURPOSE:To prevent hunting of the number of revolutions due to an increase in the width of a change in an air-fuel ratio during load running, by a method wherein, only when an exhaust gas concentration detecting value exceeds a first reference value or is below a second reference value, proportional and integral control is effected. CONSTITUTION:Based on the detecting value of an O2 sensor 17 situated in an exhaust pipe 15, a control circuit 2 performs feedback control of the opening of a linear solenoid type electromagnetic valve 10 situated in a secondary air feed pipe 9 so that an air-fuel ratio is adjusted to a desired value according to an operating state. by means of the control circuit 2, a value responding to an air-fuel ratio slightly near the rich side than a theoretical air-fuel ratio is set as a first reference value and a value responding to an air-fuel ratio slightly near the lean side is set as a second reference value. Only when the detecting value of the O2 sensor 17 exceeds the first reference value or is below the second reference value, a value equivalent to a proportion or a integral amount serving as a correction factor for feedback control is computed to output it to an electromagnetic valve 10.

Title: Muting circuit
Inventor: IIDA TAKESHI
IPC: H03F1/00
Filed: 1985-05-13
Abstract: PURPOSE:To decrease click noise at muting release by turning off a constant current source during muting and turning on the 1st and 2nd switching means so as to decrease the current consumption during the muting. CONSTITUTION:In turning on a muting switch 24, a transistor (TR) 10 is turned on, TRs 12, 13 are turned off, no current is fed to an output amplifier 1, which is turned off. Since the TR 11 is turned off, a collector current flows to the TR14 by a current mirror comprising of the TR14 and a diode 16 and the electric charge in an output capacitor 2 is discharged by constant current through the current mirror comprising of a TR15 and a diode 18. On the other hand, the capacitor 3 is charged by the current mirror comprising of a TR9 and a diode 16. Thus, no current flows to the amplifier 1 during the muting period and the amplifier 1 rises from zero at the release of muting and no click noise is generated.

Abstract: PURPOSE:To prevent generation of a slip in a wheel smoothed in its action in the time of turning by disconnecting a clutch cutting off transmission of power to the front wheel when the rear wheel is steered by an angle not less than the predetermined steering angle. CONSTITUTION:A rear wheel 9 obtains a steering angle not less than the predetermined steering angle, when the turning center O comes in the vicinity of the outer in one side of a front wheel 6, a detecting cam 11 comes into contact with a cam roller 158, because one detecting arm 112 swivels in an arrow head direction about a supporting shaft 113, levers 151, 153 swivels in a direction of arrow head (b) about a supporting shaft 152 through a lever 114 and a rod 115.

Title: Method for examining leakage of tank
Inventor: SAWADA KOUJI
IPC: G01M3/26
Filed: 1984-05-22
Abstract: PURPOSE:To ensure the examination of presence or absence of leakage of a tank, by a process for closing a liquid tank in an airtight manner, a process for obtaining a constant pressure-reduced state in the tank, a process for examining the increase in pressure, and a process for returning a gas into the tank. CONSTITUTION:Blank caps are provided in a breathing pipe 2 and a liquid feeding pipe 4. The inside of a tank 1 is made to be an airtight state. The position of a liquid reservoir 14 is made lower than a compact airtight container 7. A closing valve 13 is opened. As a result, a negative pressure is yielded at the upper part of the container 7. Then a closing valve 8 is opened. Part of a gas on a stored liquid 6 is moved into the container 7 through a measuring pipe 3 by said negative pressure. Thus the pressure in the space in the tank 1 is reduced. Under this state, the closing valve 8 is closed, and the upper part of the measuring pipe 3 is sealed. At this time, a difference H, between the pressure in the tank and the pressure of a reference pressure source 10 corresponding to the pressure-reduced state in the tank 1, is yielded in a manometer 11. When the tank 1 and the like leak, air is intruded from the outside, and the pressure in the tank 1 is increased. Therefore, the pressure difference H in the manometer 11 becomes small. Therefore, the leakage can be found by the reduction in pressure difference H, and necessary action can be taken.
