Abstract: PURPOSE:To achieve automation of ventilation by a method wherein when concentration of contamination in a tunnel is within a set range, a fan is driven and controlled by a program control method and when the concentration is out of the range, the fan is controlled by a feedback control method. CONSTITUTION:Pollutant concentration in a tunnel is measured by a VI meter or the like and if a measured values is within a set range, a plurality of jet fans are driven and controlled by a program control method, and if the value is out of the range, the fans are controlled by a feedback control method. Next, number of fans stored in a program memory 4 is read out at regular time intervals and the fans are driven using the number of fans and as far as the pollutant concentration is within the set range, the controlling state is maintained. If the concentration deviates from the set range, the number of fans 2 is increased or decreased based on the deviation between the pollutant concentration and a desired concentration to rapidly bring the concentration into the set range. After the lapse of a predetermined time, if there is difference between the number of times of deviation from upper limit and the number of times of deviation from lower limit, set number of fans in the memory 4 is corrected for a certain period of time.

Title: Electron beam exposer and method thereof
Inventor: EMA TAKAHIRO
IPC: H01J37/317
Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To make a current quantity to be probed on a wafer constant without any change in emission current and shot size by adjusting an absorptance of an electron beam absorbing film of a filter according to the opening area of a parts collectively transferring pattern of a mask. SOLUTION: The opening area of a parts collectively exposing pattern region on an EB mask 104 is calculated in reference to CAD data obtained during manufacture of the EB mask 104. When a desired mask pattern is selected in drawing, a block having a thickness suitable for the pattern opening area can be selected from a filter 103 for adjusting an electron beam current quantity based on correlative data between the opening area of the pattern and a previously examined membrane thickness, to be inserted onto the optical axis of the electron beam, whereby parts can be exposed collectively. The current quantity of the electron beam to be irradiated on a sample can be made constant without any change of an irradiation region and any change in irradiation beam current quantity. Consequently, it is possible to achieve a stable and, excellent beam profile without reducing a throughput.

Title: Scanner forming half-tone picture
Inventor: KAWAMURA NAOTO
IPC: H04N1/04
Filed: 1980-04-21
Abstract: PURPOSE:To obtain stable half-tone pictures without any influence of fluctuations of photosensitivity characteristics on a recording and display surface, by using a scan system which varies the number of dots of a scanning beam. CONSTITUTION:A beam emitted from semiconductor laser light source 2 is incident to the thin-film wave directing path of optical element 1. The light beam in the wave directing path is collimated by geodesic lens 3 and the parallel beam is deflected by the Bragg diffraction with a surface elastic wave generated by comb type electrode 5. This deflected light beam is focused via geodesic lens 4 to form a light spot on the projection end surface of the wave directing path. The formed image spot is scanned by rotary polygon mirror 7 at right angles to the main scan direction to draw the locus of the light beam on photosensitive drum 9. The optical output of laser 2 is turned ON/OFF synchronizing with the deflection of this optical element. The drive like this provides gradations of the density of the light dot.

Abstract: PURPOSE: To simplify the whole constitution of a hot-air generator by a method wherein the exhaust port to discharge the combustion gas through a change-over valve is allowed to changeably communicate with a hot-air duct and the heat medium duct of a heat exchanger.  
     CONSTITUTION: When the valve body (a) of the change-over valve 4 is opened, while the valve body (b) is closed, the combustion gas discharged from an exhaust port 14 of a combustion furnace 1 is directly sent into a hot-air duct D connecting to the air outlet of a fan F and diluted with the outside air taken in from an intake 70 to become a hot air of given temperature. On the other hand, when the valve body (a) of the selector valve 4 is closed, while the valve body (b) is opened, the combustion gas is allowed to flow through a heat medium duct (e) while exchanging heat with the outside air taken in from the intake 70. Thereby, said outside air becomes an indirectly-heated air of given temperature and is introduced into the hot-air duct D.

Abstract: PROBLEM TO BE SOLVED: To suppress the increase of flow resistance and to enhance the heat exchanging efficiency, by providing flow resistance attenuating means which attenuates the flow resistance of a cooling medium in a flow direction of the cooling medium in a flow passage. SOLUTION: In a flow passage R, partition wall members 13 are disposed in a vertical direction, and these partition wall members 13 are fixedly secured to an outer peripheral surface of an inside cylinder 11 and an inner peripheral surface of an outside cylinder 12, so as to divide the inside of the flow passage R into annular chambers r vertically. In the partition wall members 13, the length of outside cylindrical portions 13c is set such that it is made gradually longer corresponding to the position of the partition wall member 13 in an upward direction and accordingly, the volume of the annular chambers r is determined corresponding to the length of the outside cylindrical portions 13c such that it is made gradually increased corresponding to the position of the annular chamber r in an upward direction.  Although a cooling medium is in a liquid state condition at the time of entering the flow passage R from an inlet pipe, the cooling medium is vigorously evaporated at portions thereof which come into contact with the inner sleeve 11 during its flow, flows in the annular chamber r1-r7 at a high speed while gradually increasing the rate of gas phase C2/liquid phase C1, and performs the heat exchange with water for ice making in the inner sleeve 11, thus enhancing the heat exchange efficiency.

IPC: B21D24/00
Filed: 1997-02-21
Abstract: PROBLEM TO BE SOLVED: To project and form a projecting part which is over the upper limit of elongation percentage and to obtain a projecting part without brittleness. SOLUTION: In this pressing method, in a process where the projecting part 7 is formed from a base stock 6, the projecting part 7 is plastically deformed by pressing it in the thickness direction. In a press die, the clearance between a projecting part 4 and a recessed part 2a is set smaller than the thickness of the base stock 6 in a state where a male die 1 and female die 2 are in press- contact. The projecting part 7 of a pressed product has thinner thickness (t1 ) than the thickness (t0 ) of the base stock and the thinner thickness part is compressed in the thickness direction.  In this way, a large projecting part 7 can be projected and formed without generating cracks, the press die is manufactured at equal cost to that in conventional method and the projecting part is prevented from becoming brittle by being compressed in the thickness direction, so, even when the amount of projection of the projecting part is larger, the pressed product has high quality.

Title: Projection exposure apparatus
Inventor: SUWA KYOICHI
IPC: H01L21/027
Filed: 1989-03-07
Abstract: PURPOSE:To transfer fine patterns without extreme increase of the number of openings of a projection optic system and extreme reduction in wavelength of illuminating light by a method wherein the projection optic system for projection exposing a mask pattern on a wafer is provided with specific spherical aberration characteristics in advance. CONSTITUTION:When a light beam which passes through the most outward part in an iris EP is assumed to be l1 and a light beam which passes through the most inward part is to be l2, deflection deltaZh along an optical axis between a focus with the light beam l1 (on image surface IP) and that with the light beam l2 is spherical aberration. This spherical aberration is made to be generated to a certain degree. In other words, where widths of aberration deltaZ1, deltaZ2 with characteristics CV1, CV2 are spherical yields on the respective points on the image surface, focus depth can be increased by increasing the width deltaZ1 or deltaZ2. Although contrast characteristics slightly deteriorate by the above operation, wide focus depth can be secured, thereby enabling transfer of fine patterns without increase in the number of openings and reduction in wavelength of the light.
