Abstract: PURPOSE: A thickness of a photoresist layer on a wafer can be checked at a desired position of the wafer by transferring a monitoring pattern on the wafer being performed real processes. CONSTITUTION: Separate patterns capable of monitoring the thickness of a photoresist layer are formed on a reticle to be used for a photolithography process. In the photolithography process, the monitoring patterns(12,14,...) are transferred to a predetermined region, preferably, a scribe line, of a real wafer. Preferably, the monitoring patterns(12,14,...) are formed as patterns such as, for example, a cross-type pattern(A) or a vertical-type pattern(B), which a measuring device can easily recognize. Also, the size(a,b) of the monitoring patterns(12,14,...) can be controlled optionally. In addition, the monitoring patterns(12,14,...) formed in the scribe line do not affect circuitry patterns of a main chip region, allowing an easy check on the thickness of the photoresist layer.

Abstract: PURPOSE: A bicycle saddle is provided to give comfortableness to a driver by supporting the load of the driver on a hipbone and a thighbone portion and by remarkably reducing the load on a genital organ. CONSTITUTION: A saddle forms a ventilating channel in the front portion and a ventilating hole in the entrance of the ventilating channel. The ventilating hole is closed by a ventilating hole stopper. The ventilating channel is formed between the frame of a variable saddle(3) and the frame of a peripheral saddle. Then, air flows to many small ventilating holes(210) in the side of a central groove and small pores(210') in the side of the variable saddle through a space between the frames. The central groove forms partitions easily passing air through a channel(212). When the ventilating hole stopper is opened and a bicycle is moved forward, air is discharged outside through the pores. The height of the variable saddle is adjusted by springs(232) between the frames of the variable saddle and the peripheral saddle.

Abstract: PURPOSE: An oil fire extinguishing method of a fire extinguisher is provided to reduce a cost by extinguishing a fire with water instead of an imported extinguishing agent and to prevent cookers and dishes from being corroded by the extinguishing agent. CONSTITUTION: To extinguish oil fire on a cooker with water, water is injected in a vortex shape by many vortex guiding grooves (112) on the outer circumference of a vortex injecting tip (111) inside a nozzle (102). Then, the water forms a water film to intercept oxygen. Further, the water hits on a slant face (104) and water from a linear guiding groove (113) of the vortex injecting tip at the same time to be water particles similar to oil particles. Thus, water particles and oil particles are mixed well and condensed oil is split and covered by the water particles. The water particles cool the oil to lower the temperature of the oil under the ignition point of the oil. Finally, oil fire is extinguished. Due to an adjusting cap (103) combined with the nozzle, the radius of the water film is adjusted.
