Title: Combustion device of liquid fuel
Inventor: WATANABE EIICHI
IPC: F23Q25/00
Filed: 1978-03-30
Abstract: PURPOSE: To improve handling ease and simplify construction in the earthquake- proof fire extinguishing structure of a liquid fuel combustion device by providing a cut off part on a ratchet wheel connected to a wick shaft which moves up and down a wick and making the reset at the time of quakes automatic.  
     CONSTITUTION: When a wick is raised, a ratchet wheel 7 rotates in the direction of arrow mark K pushing a reset lever 16 against a spring 21 with teeth 7'. When the stopping projection 9 of the ratchet wheel 7 touches the lower end of the lever 16, rotation is stopped, the tooth 7' engages with the ratchet pawl 20 of the reset lever 16 and the reversing of the ratchet wheel is prevented. At this time, the other end of the reset lever 16 becomes almost horizontal and non-contacted with a working plate 17, therefore, if quakes occur, a sensor 13 falls down. If the sensor 13 falls down, the end of the reset lever 16 and the ratchet wheel 7 are disengaged, and since the wick is always energized downwards, the wick falls instantly and fire is extinguished.

Title: Separator for battery
Inventor: YAMAZAKI HIROAKI
IPC: H01M2/18
Filed: 1992-01-29
Abstract: PURPOSE:To maintain the shape of a separator while resisting the pressure at the time of charge and discharge, and hold the electrolyte with hollow holes and pores by using the porous hollow fiber as a separator for battery. CONSTITUTION:As the fiber to be used, the porous hollow fiber 5, which has two or more of hollow holes for dividing the inside of a fiber in the longitudinal direction and which has pores 4 for communicating the hollow holes 3 and the surface 1 of the fiber, is used. The electrolyte penetrates from the pores 4 to the hollow holes 3, and is held in the fiber 5. Since the inner wall exists between the hollow holes 3, the force for resisting the pressure is given to the fiber 5. Such a fiber 5 can be obtained by spinning with the ordinary compound spinning method, and thereafter, by extracting the resin component for elimination from the parts of the hollow holes 3 and the pores 4. The strength of the separator is thereby improved, and in the case of a secondary battery, even if the pressure is applied to the separator at the time of winding between the plates and at the time of charge and discharge, the separator can hold the electrolyte.
