Abstract: PURPOSE:To prevent the occurrence of a flood due to an abnormal rise of the water level by raising the water level in an intake pipe upstream an impeller than the water level of a water intake well via the action of a water level raising means, and opening a pump discharge valve for the air operation. CONSTITUTION:A vacuum pump IWL setting the sealed space 12 to the negative pressure when a discharge valve 7 is fully opened and sucking and lifting the water level IWL in an intake pipe 4 than the water level of a water intake well 1 by H2 is arranged on a vacuum system 2, and the raised quantity H2 of the water level IWL is properly maintained by the operation control of the vacuum pump 20 based on the pressure detection signal of a pressure switch 23. When the water level of the water intake well 1 reaches the pumping start water level HWL, the water level in the intake pipe 4 is raised to the level higher than it by H2, i.e., the water level that the horizontal shaft pump can drain water via the self-suction capability. When the water level of the water intake well 1 reaches the pumping start water level HWL, the air operation is immediately switched to the pumping operation.

Title: Heating method of flat plate and heater
Inventor: SHOJI HAJIME
IPC: H05B3/00
Filed: 1992-09-03
Abstract: PURPOSE:To form a resin film on a substrate at a uniform thickness by dividing suction holes into at least two groups to execute vacuum evacuation by switching among the groups, and whereby adhering the substrate to a hot plate. CONSTITUTION:When a glass substrate on which a photoresist is applied, for example, is put on a hot plate 3, it is sucked in vacuum, and is heated. Suction holes are divided into three groups, for example, and vacuum evacuation is executed by electromagnetic valves 1A, 1B, 1C through vacuum piping 2A, 2B, 2C. The substrate is not continuously sucked by the same suction hole, but can be sucked by a plurality of suction holes belonging to different groups. Since the temperature of the substrate in the vicinity of the suction holes is not easily reduced, difference in the temperature distribution is reduced. A photoresist film of a uniform thickness can thus be formed.

Abstract: PURPOSE:To contrive the significant improvement of an alignment accuracy by a method wherein the amount of deformation of an alignment object is found, this amount of deformation is subtracted from measured data to correct the deformation of the alignment object and after this deformation correction, a correction on an error due to the deformation of the alignment object itself is again executed.

Then, an error arithmetic part 52 finds an error on each mark according to measured data from the detection systems and the amount of deformation from the arithmetic part 51. Moreover, an exclusion part 53 excludes data having an error of a value higher than a specified rated value among data from the arithmetic part 52. Then, a correction arithmetic part 54 corrects and operates the amount of deformation of the wafer by using a data group subsequent to the exclusion. Lastly, a controller 55 controls motors 37 and 38 respectively on the basis of the amount of deformation corrected and operated by the arithmetic part 54 and executes an alignment work. Thereby, it becomes possible to correct a correction on an error due to the deformation of an alignment object itself as well.

Abstract: PURPOSE:To prevent the deviation in the direction of a through hole and the rotational deviation in the circumferential direction and to surely support a honeycomb structure by projecting or recessing at least a part of the outer wall surface to form a step and making the surface of the protrusion or recess rougher than the other wall surface. CONSTITUTION:The periphery of a ceramic honeycomb structure 1 is sandblasted to cut the surface of the part, and a recess 2 is formed. When the honeycomb structure 1 thus obtained is incorporated as a converter along with a sealant and/or a cushion material 5, the sealant and/or the cushion material 5 are thrusted into the recess 2, hence the structure 1 is firmly supported, and the deviation in the direction of the through hole and the rotational deviation in the circumferential direction can be effectively prevented even if the structure is supported only in the radial direction. When the protrusion is formed by a ceramic material slurry or ceramic grains, the honeycomb structure has the same effect.

Abstract: PURPOSE:To flatten the surface of a semiconductor device by applying an insulator, having an etching speed equal to that of an oxide film, on the oxide film of bird's head part and etching the insulator. CONSTITUTION:To a swollen part of an oxide film 9, referred to as a bird's head 8, generated when an element forming part and a LOCOS part are flatten to have the same height, a resist 10 having an etching speed equal to that of an oxide film 9 is applied after a silicon nitride film used as a mask is removed, then dry etching is carried out, and when the etching is finished, the bird's head part 8 is also etched so that the oxide film 9 is flattened. Thus, when exposure is effected using a high viscosity resist, the occurrence of the step-cut of the resist or the occurrence of disconnection of a two layer wiring, passing over the bird's head part 8, caused by the exposure defect due to the step can be prevented.
