Title: Method and device for supply of fuel in internal combustion engine
Inventor: TOMITA TAKAO
IPC: F02B25/20
Filed: 1981-06-22
Abstract: PURPOSE:To control the lowering of output of the titled engine to the minimum, to save the cost of fuel and to extend the life of the engine by reducing the combustion load by a method wherein in case the engine is of four stroke type, the supply of the fuel to the engine and the stopping of the supply are performed at the time of the air intake stroke of a piston. CONSTITUTION:When a rotary type changeover valve 17 is opened as shown by the solid line in the air intake stroke of the piston 5 moving upward, a gas mixture is sucked into a chamber (a) and when the piston shifts to its expansion and exhaust stroke, it moves down and an exhaust gas passage 12 and a scavenging passage 10 communicate with a cylinder 4 so that the gas mixture in the chamber (a) is compressed to flow into the cylinder 4 to thereby scavenge the burned gas and to fill the cylinder 4 with a fresh gas mixture. Thus, when the piston begins to take the next stroke, the changeover valve 17 which turned by 180 deg. during the previous stroke now interrupts the passage 14 as shown by the chain line and at the same time, makes a passage 16 communicate with the chamber (a) so that only fresh air enters the chamber (a) and the cylinder 4 is scavenged sufficiently and cooled effectively.

Abstract: PURPOSE:To make it possible to such a fixed amount of a liquid at any time by calculating a liquid level in every suction of a dispensing nozzle from an initial liquid level and by exercising control so that the dispensing nozzle will intrude into the liquid to a fixed extent of depth from the liquid level in accordance with the liquid level. CONSTITUTION:The distance from the bottom surface of each tank 1 to the upper dead point of dispensing nozzle 3 is denoted as H, and the extent to which the dispensing nozzle is intruded into each liquid 2 is also denoted as S; and initial liquid levels of respective liquids 2 are denoted as h1...hn, and liquid-level drops in single suction are denoted as K1...Kn in tank 1. Here, the lowering extent of dispensing nozzle 3 in initial suction is H-hn+S and that in N-th suction is H-hn+S+ (N-1)Kn, so that dispensing nozzle 3 will intrude into the liquid by constant extent S. Therefore, controller 20 solves those formulas and in accordance with the calculated value, dispensing-nozzle elevating motor 10 is driven, permitting nozzle 3 to intrude into the liquid by constant extent S at any time. Further, if the calculated value exceeds a certain value, warning unit 22 is driven with a signal from unit 20 to give warning of the remaining amount. Thus, a fixed amount of the liquid can be sucked at any time.

Title: Protection of controlled rectifier
Inventor: IKEDA HIROSHI
IPC: H02M7/12
Filed: 1978-08-09
Abstract: PURPOSE: To smoothly correct the failure in commutation and resume operation, by adding a failure-time turn-on angle setting circuit, an analogue switch and a simple electronic circuit such as a turn-on advancement priority circuit to a conventional system for protection against the failure in cimmutation.  
     CONSTITUTION: In a main circuit, the DC output voltage of a controlled rectifier unit 3-1 is zero and that of another controlled rectifier unit 3-2 is positive. Since a load current flows through the controlled rectifier unit 3-2 and load 4 and is going to flow from the rectifier unit 3-2 to the other 3-1, the current of the unit 3-1 decreases sharply. The failure in commutation takes place when a commutation margin angle γ=180°-α-u falls below a predetermined value. Since the current flowing through controlled rectifier elements decreases in the commutation overlap angle u, the failure in commutation can be smoothly corrected by reducing the current of the controlled rectifier unit 3-1.
