Filed: 1983-11-17
Abstract: PURPOSE:To decrease the coefficient of fuel consumption and to reduce contamination of the air, by a method wherein an air suction passage is communicated with a scavenging passage through a check valve, and a mixture suction passage is communicated with a crank chmaber. CONSTITUTION:With a piston 20 raised, scavenging holes 15a and 16a are closed and the interior of a cylinder is compressed, a crank chamber 14, simultaneously, is reduced in a pressure, and with check valves 31 and 41 opened, fuel-air mixture flows in a crank chamber 14, and air flows in scavenging passage 15, 15, and 16. Thereafter, a pistong 20 is lowered through expansion, exhaust gas is exhausted through an exhaust hole 18. When, with the piston further lowered, the scavenging holes 15a, 15a, and 16a are opened, the previously compressed air is first blown in a combustion chamber 17, and residual air is pushed out thereby. Consecutively, fuel-air mixture is blown in a cylinder.

Title: Automatic frequency control circuit
Inventor: YAMAGUCHI SHOJI
IPC: H04N5/12
Filed: 1987-08-31
Abstract: PURPOSE:To obtain a pull-in frequency range corresponding to a horizontal synchronizing frequency, by changing a phase detecting output according to the horizontal synchronizing frequency. CONSTITUTION:In the timing of a horizontal synchronizing period, a differential amplifying circuit 3 executes a comparing action and sends a phase detecting output AFC according to a difference in degrees between a constant voltage signal V1 and a superimposing signal CON, and simultaneously, according to a constant current I. Consequently, the wave-height value of the phase detecting output AFC at such a time goes to a large one since the value of the constant current I is large in such a way, even if the difference between the constant voltage signal V1 and the superimposing signal CON is fixed. In such a way, since the value of the phase detecting output AFC is made changeable according to the horizontal synchronizing frequency, the pull-in frequency range corresponding to the horizontal synchronizing frequency can be obtained.

Abstract: PURPOSE:To reduce NOx and improve efficiency of combustion by detecting outflow temperature at a medium outlet to control air fuel ratio according to said temperature while regulating fuel supply downstream of the medium according to the air fuel ratio. CONSTITUTION:Outflow temperature at a medium outlet is detected by a thermometer 9. When said temperature is lower than fire point of thin fuel, an electromagnetic 10 for supplying fuel to a portion downstream of the medium is closed to reduce fuel supply from said portion and increase and air fuel raio in mixture supplied from a portion upstream of the medium. And when the temperature detected by the thermometer 19 exceeds the heat resisting temperature of the medium, said operation is reversely carried out.

Title: Smoke dividing device
Inventor: IKEGAMI YOSHIHIRO
IPC: B64D13/00
Filed: 1997-08-12
Abstract: PROBLEM TO BE SOLVED: To divide the circulation of the air between smoking seats and non- smoking seats using an air curtain as a boundary to prevent the air on a smoking seat side from flowing onto a non-smoking seat side by providing the air curtain between a smoking room and a non-smoking room to eliminate the circulation of the air between the smoking room and the non-smoking room. SOLUTION: In a guest room of an aircraft, for example, the air which passes an engine and flows in is blown out into a passage 9 between smoking seats 1 and non-smoking seats 2 by an air blowing out device to form an air curtain 8. In this case, an air blowing out port 3 keeps an angle of 5 deg. for a floor surface and vertical direction. A wall which shuts off the flow of the air is formed between the smoking seats 1 and the non-smoking seats 2 by this air curtain. Furthermore, the air which constitutes the air curtain 8 flows into a lower part of the seat which is a lower part of an aircraft body and goes upward along a wall of the body. The air which rises circulates on the smoking seats again and scarcely flows onto the non-smoking seats which are the other parts in the body.

Title: Switch-over valve for high temperature gas
Inventor: YASUDA TSUTOMU
IPC: F16K27/04
Filed: 1995-08-25
Abstract: PROBLEM TO BE SOLVED: To make the switch-over of the flow direction for high temperature gas by introducing high temperature gas from either one of spaces with a rotor rotated, and also exhausting it to an external flow path connected to a housing. SOLUTION: In a rotor 1, ports 6 and 7 which communicate with a space 9 within a housing respectively, are formed one by one in one space 4 and in the other space 5 while a partition 3 is held in between in a place close to the partition 3. The ports 6 and 7 are formed while a distance is spaced by 180 deg. in such a way as to be disposed at the opposite places. The interposition of a semi-cylindrical bush 10 between the housing 2 at the opposite side of an exhaust port 8 allows a space 9 to be formed only at the exhaust port 8 side while being interspaced from the rotor 1, and therefore, either one of the ports, that is, the port 6 or 7 communicates with the space 9 within the housing. A gear 11 as a rotation transmitting means is integrally formed over the rotor 1, and fluid flow is thereby switched over by rotating the rotor 1.

Abstract: PURPOSE:To improve power and fuel consumption regardless of type of fuel by controlling both an ignition timing responding to the knocking detected output and a supercharged pressure according to an ignition timing map prepared with relation to octane value and supercharged pressure data determined according to the map, respectively. CONSTITUTION:When control for high-octane gasoline is discriminated in an interruption routine, a supercharged pressure is set to a higher value so that a waist gate valve 22 will not be opened until the supercharged pressure reaches the high level. When ignition timing arithmetic operation is performed using a high-octane gasoline ignition timing map and occurrence of knocking is detected from the output of a knocking sensor 12, whether successive occurrence of the knockings has been made or not is discriminated and if precedent knocking is not found, ignition timing is delayed by a certain angle. If successive occurrence of knockings has been made, the octane number is found improper and thereafter ignition control as of regular gasoline is performed. When the control performed when regular gasoline is used is discriminated, the supercharged pressure is set to the lower pressure level and arithmetic operation of ignition timing is executed according to a regular gasoline ignition timing map to provide the optimum output.
