Title: Combustion safety device for gas equipment
Inventor: TAMADA KAZUMI
IPC: F23N5/24
Filed: 1981-02-02
Abstract: PURPOSE:To improve an accuracy of sending of oxygen deficience when a weak combustion is performed by a method wherein a semiconductor sensor for a discharged gas of a combustion safety device in a double stepped combustion change-over gas combustion unit is arranged at a positon corresponding to a strong combustion flame and at the same time an intermittent strong combustion is performed when a weak combustion is performed. CONSTITUTION:Strong combustion flame is set at a condition F1 when a strong combustion is performed, and then returned back to a condition F2 when oxygen is reduced, resulting in that the hood 8 is convered to eliminate a bi-flow of air to cause the electrode 7a in the sensor 7 to show a low electromotive force and to operate the safety valve 3. When weak combustion is found, even if a lift-up phenomenum is occured, no covering of the hood 8 by the lift-up flame F2 is made and the sensor 7 is not operated thereby. Therefore, when the weak combustion is performed, a volume of inermittent supplying of gas is increased to enable the lift-up flame to cover the hood with the flame being set to a strong combustion condition. Thereby, a positive sensing of lack of oxygen may be performed whenever a strong or a weak cmbustion is made and a safety device may be operated.

Filed: 1981-01-31
Abstract: PURPOSE:To control a moving speed of an operating piston and to enable operating of a hydraulic lift at a set, speed, by a method wherein a total discharge of a pump is fed to a control valve for lifting, and oil is fed to a control valve for external oil pressure via a discharge control valve. CONSTITUTION:A discharge control valve 11 is connected between a feed side oil path 9 from a pump 1 to an external oil pressure control valve like a control valve of an elevating piston 3a of a lift arm and a return side oil path 10 from a control valve 4 for external oil pressure, for example, a control valve for damp piston 5a, turning a working machinery to a control valve 7 for lifting. If a discharge of pressure oil flowing the feed side oil path 9 exceeds a given amount, the connection causes feeding of surplus oil, passing through the control valve 11, to the control valve 7 for lifting from the return side oil path 10. As noted, the pressure oil controlled to a given amount is fed to the control valve 2 and 4 for external oil pressure, and this permits the control of a moving speed of an operating piston.

Title: Cleaning device of fine particle in exhaust gas for internal combustion engine
Inventor: TAKAGI SHIGERU
IPC: F01N3/025
Filed: 1981-02-03
Abstract: PURPOSE:To minimize leak of gas from a cleaning device for fine particle contained in exhaust gas, by providing an exhaust-gas-fine-particle-capturing unit member with an outside covering made of a material having a larger ventilation resistance, and also by providing an annular seal between the outside covering and a casing. CONSTITUTION:Exhaust gas containing fine particles goes from an intake 17 of a cleaning device into a fine-particle-capturing material 10 made of ceramic. While the gas in the fine-particle-capturing material 10 is trying to leak out from the outside circumference, since it is enclosed by the material having a larger ventilation resistance, it is not allowed to leak out from the outside circumferencial area in any case. And, although the gas at the intake 17 is trying to leak out through a gap between the fine-particle-capturing material 10 and a casing 12, as an annular elastic seal 28 is pressed into the gap, the gas is prevented from leaking out. Thus cleaned exhaust gas is then discharged from an exit 19 to outside.
