Filed: 1990-02-09
Abstract: PURPOSE:To prevent hoarfrost formation in open culture by a simple device by arranging a burner in cultivated land of crops, forming a pilot flame and producing air convection action based on gas combustion in reduction temperature of the open air. CONSTITUTION:A temperature sensor 8 consists of a thermister, a resistance thermometer bulb, etc. When temperature of the open air is dropped <=a preset temperature (e.g. 4 deg.C), the temperature sensor detects the reduction in temperature, operates a temperature actuator and closes a feed circuit 10 of a solenoid valve 6. The solenoid valve 6 maintains wholly closed attitude when the temperature of the open air is higher than a set temperature and the solenoid valve is made into a wholly closed attitude when the temperature of the open air is dropped to <= the set temperature. A throttle valve 7 can make an amount of gas fed from a pilot gas passageway 5 maintain whole burners 1 in a stable pilot flame. Further, an amount of throttling of a gas for forming major flame is set in such a way that when the gas is supplied from a main gas feed passageway 4, the gas amount is made to transfer the pilot flame into the main flame without being blown out by jetting gas pressure.

Number and fineness of the elastic filament yarn to be inserted into the main knit S and power-raised knit P are controlled, so as to change power of the knit. Quantities of the filament yarns to be supplied for the main knit S and power-raised knit P are controlled, so as to solve problems associated with puckering and/or curved knit. This knit is suitable for inner wear.

A heating element 30 is stuck to the outer surfaces of the plate bodies over the width nearly equal to the width dimension of the photosensitive and pressure sensitive recording medium 1. The leading end of the medium 1 exposed and pressure-developed enters a gap on the edge sides of the plate bodies 25 and 26 while widening the gap, the wide surfaces of the plate bodies 25 and 26 slide on the front and the back surfaces of the passing medium 1 and a color image is thermally fixed by imparting the heat.  Since the heat is imparted to the both upper and lower surfaces of the medium 1 for a comparatively long time while moving the medium 1, the large quantity of the heat is imparted to the medium 1 at a comparatively low temperature.
