Title: Snow melting device
Inventor: INOUE HITOSHI
IPC: E01C11/26
Filed: 1989-09-13
Abstract: PURPOSE:To improve the snow melting faculty by suppressing the exfoliation between one side of a heat pipe and a heat radiation panel due to vibration by forming an accommodating groove which accommodates a part on the other side of a heat pipe formed on the heat radiation panel, in thermal contact with the heat radiation panel and supports said part in vibrationproof manners. CONSTITUTION:One edge side 9a of a heat pipe 9 is heated by the heat in the soil 2, and the working fluid in the heat pipe 9 is vaporized, and transferred to the other side 9b of the heat pipe 9. Since the temperature of a heat radiation panel 10 arranged in a snow storage groove 7 is lower than that of the soil 2, the vapor of the working fluid is condensed and liquefied, and liberates the condensation latent heat into the hat radiation panel 10. Further, the heat radiation panel 10 is heated by the condensation latent heat, and the temperature is raised, and the liquefied working fluid is returned to one side 9a of the heat pipe 9. Through the natural repetition of the above-described operations, snow 8 is melting-processed, and the heat transmission area is increased by an accommodation groove 11 between the other side 9b of the heat pipe 9 and the heat radiation panel 10, and the snow melting faculty is improved drastically.

Title: Fluidized bed furnace
Inventor: KAWATE KENJI
IPC: C21D1/53
Filed: 1987-09-22
Abstract: PURPOSE: To save the amount of use of gas and rapidly and uniformly heat a material to be heated by increasing the amount of injection of fluidized gas at an initial stage of temperature rise of the material, and gradually reducing the amount in the course of the temperature rise. CONSTITUTION: In an early stage of temperature rise of a material to be heated having a large difference between a set temperature in an arithmetic device 51 and an actually measured temperature of the material, the amount of injection of fluidized gas is increased and a heat transfer speed between fluidized particles 31 in a retort 14 is speeded up, whereby the material is rapidly heated. In the course of the temperature rise of the material that a difference between set temperature of the device 51 and the actually measured temperature of the material is reduced, the amount of injection of the gas is gradually reduced in response to the temperature difference and hence the amount of use of the gas is saved, whereby the material is uniformly heated to the set temperature.  Further, the material is transferred to a furnace installed separately and kept at regulated temperature while a fluidized bed furnace is simultaneously used for heating of a new material to be heated. Hereby, the amount of the use of the gas is reduced and further the material is rapidly and uniformly heated.

Abstract: PURPOSE:To compensate for the strain in a frame and the change in characteristics of optical displacement gages in calibration and to make it possible to measure the thickness of a plate accurately by correcting the outputs of the optical displacement gages and a reference distance based on a linearity correcting table and a calibration table. CONSTITUTION:The outputs of optical displacement gages are made to correspond to the expected upper and lower positions of the optical displacement gages 18 in linearity calibration with a linearity correcting means based on a linearity correcting table. Such a table is prepared. A reference distance is obtained based on the outputs of the optical displacement gages 18 when a frame is calibrated and the plate thickness of a calibrating plate 28 with a frame correcting means. A calibrating table by which the reference distance is made to correspond to the right and left positions of the optical displacement gages 18 is prepared. Then, the distance between each optical displacement gage 18 and a body under measurement 10 is corrected in reference to the linearity correcting table with a plate-thickness operating means. The reference distance is corrected in reference to the calibrating table based on the right and left positions of the optical displacement gages 18. The plate thicknesses of the body under measurement 10 are operated and averaged at several points on the locus based on the upper and lower moving amounts of the optical displacement gages 18, the corrected distances and the reference distance. Thus, the plate thickness can be measured accurately.

Abstract: PROBLEM TO BE SOLVED: To make the light control time during scan measurement shorter or constant by measuring the optimum light quantity or gain of each detecting point before making the scan measurement and setting the previously found optimum light quantity or gain at each detecting point at the time of making the scan measurement. SOLUTION: Before making exposure treatment on a wafer 4, light control data are obtained by scanning the wafer 4 by making sample shots with the light from a light source 10 while the illuminance of the light is maintained constantly and receiving reflected light from each detecting point by means of a photoelectric conversion means 19 and a set current value which becomes the optimum peak value for focus exposure during scan exposure is calculated from the obtained data and stored. In the exposure treatment of each shot, the measuring positions are successively illuminated with the set current corresponding to the reflectivity of the measuring positions so as to make the shape (peak) of the waveform to be measured constant regardless of the reflectivity.  Therefore, the light control time during scan exposure can be shortened and surface position detection can be performed with higher accuracy.

Abstract: PURPOSE: To obtain a scanning probe microscope in which a high-speed scanning operation can be performed by a method wherein the diameter of at least one circumferential face between both end parts of a nearly cylindrical piezoelectric driving body whose diameters at both ends are different is constituted so as to be changed monotonously between both end parts. CONSTITUTION: A piezoelectric driving body 1 comprises two end parts 2, 3, their diameters are formed so as to be different, and a truncated cone shape is constituted. The truncated cone shape comprises an outer circumferential face 4 and an inner circumferential face 5, and cross sections which are perpendicular to the axial direction are circles. An electrode 7 is installed at the inner circumferential face 5, and divided electrodes 6 are installed at the outer circumferential face 4. The electrode 7 is grounded, and a voltage is applied selectively to one out of the divided electrodes 6. Then, when the voltage is applied to the electrode 6, the driving body 1 is crooked.  When the large-diameter end part of the driving body 1 is fixed to the fixation side of a scanning probe microscope, the small-diameter end part is crooked in a direction perpendicular to the driving body 1 due to a strain. Since the rigidity of the driving body 1 and that of a mounting part are high, the scanning probe microscope can scan a probe at high speed due to the strain of the driving body 1.
