Title: Evaporator for vapor phase growth
Inventor: EBE KOJI
IPC: H01L21/205
Filed: 1990-06-05
Abstract: PURPOSE:To obtain an evaporator, for vapor growth use, by which a raw- material gas for epitaxial growth use can easily be obtained by a method wherein a gas inflow tube is bent to be L-shaped, its tip part is sealed and many small holes are formed in its tube wall. CONSTITUTION:A gas inflow tube 22 which has been inserted into a raw- material liquid such as mercury which is housed in an evaporator 21 is bent to be L-shaped; its tip part is sealed. Many small holes 23 are formed in a part which has been bent to be L-shaped. Thereby, a carrier gas which has flowed out from the many small holes 23 comes into contact with mercury as the raw-material liquid in larger quantities than in conventional evaporators and sufficiently. As a result, it is not required to heat the evaporator to a high temperature like the conventional evaporators. Thereby, the heating temperature of the mercury evaporator is at about 100 deg.C or lower. At this temperature, a precision pressure regulator and a gas flow-rate control valve using a fluorine rubber can be used.

Title: Annealing of substrate
Inventor: SHINPO MASAFUMI
IPC: H01L21/324
Filed: 1987-06-15
Abstract: PURPOSE:To dispense with the mask film on the side of the rear of a substrate by a method wherein, with the rear side of the substrate exposed in a second chamber, the substrate is heated in a state that the interior of the second cham ber is purged with a second gas atmosphere. CONSTITUTION:A chamber 3, wherein a substrate 1 is installed, is separated into first and second chambers 31 and 32. The surface side of the substrate 1 is exposed in the first chamber 31 in such a way that the surface side is brought into contact to a prescribed first gas atmosphere 50 and with the rear side of the substrate 1 exposed in the second chamber 32, the substrate 1 is heated in a state that the interior of the chamber 32 is purged with a second gas atmosphere 51. Rapid annealing, which is executed by heaters, lamps, a laser and so on with ultraviolet rays, light or the like, is desirable for the heating in order to increase productivity. Accordingly, the mutual inclusion of impurities in the same substrate 1 can be easily prevented. Thereby, simplifica tion of a process, such as a fact that it becomes unnecessary to coat a mask film on the rear of the epitaxial wafer, becomes possible in an Si process.

Title: Removal of low boiling point noxious substance
Inventor: OKADA MITSUHIRO
IPC: B01D53/64
Filed: 1984-07-19
Abstract: PURPOSE:To remove the low b.p. substance such as mercury contained in the exhaust gas from an incinerator, by the abrupt change in the temp. of gas and the contact (or collision) of the gas with water. CONSTITUTION:In a method for removing the low b.p. substance in the exhaust gas from an incinerator according to an absorbing tower system, a process generating the abrupt change in temp. over 130-250 deg.C and simultaneously contacting water with the gas is performed in two stages. For example, the exhaust gas from the incinerator is guided to a first absorbing tower 1 by a blower while the dust therein is removed by a dust collector. The inlet gas temp. of the first absorbing tower is 200-300 deg.C but cooled to 65-85 deg.C through the contact with a recirculation liquid. The gas after cooling is again heated to 180-250 deg.C by a gas heater 2 and, thereafter, introduced into a second absorbing tower 3 to be cooled so as to bring the outlet gas temp. of said tower to about 40-70 deg.C. The exhaust gas issued from the second absorbing tower is discharged to the atmosphere through a white smoke preventing apparatus 4.

Title: Finishing device for testing die
Inventor: ENDO YASUHIRO
IPC: B29C45/64
Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To avoid the problems of greatly increased manufacturing costs and the necessity of a large area and broad space for installation because a type of the top and bottom clamping of the dies in the conventional finishing device for testing dies causes the necessity of a long, thick frame in the longitudinal direction such as a large-sized press machine as well as the use of a large-scale die plate reverse system, a large-sized hydraulic cylinder or the like. SOLUTION: A non-slidable die plate fitting base 43 fitted with one die plate d1 is supported by a fixed base 23 while a slidable die plate fitting base 45 fitted with the other die plate d2 is supported by a horizontally movable slide base 35, each of which can be freely switched between the working postures in vertically closing the die and that in turning the die face up. The die clamping can be achieved by pulling the two die plate fitting bases close to one another from the state where each of the die plates is adjacent to one another by a die clamping cylinder 91. This results in a small-sized device and lower costs.

Filed: 1993-06-21
Abstract: PURPOSE:To reduce cost and to accurately detect the shortage of toner. CONSTITUTION:A current I flowing through a developing roller shaft 30 is detected by a current detection circuit 38 when development is not performed. When the toner is sufficient, the current I flows by friction between the toner 22 and a toner supply roller 24, a developing roller 26 and a doctor blade 28, and when the toner is insufficient, it becomes larger by the friction between the blade 28 and the developing roller 26. Reference values Is1 and Is2 based on which the shortage of the toner and insufficient electrostatic charged amount are judged are previously set, and compared with the current I by a comparison circuit 40. When I>Is1 is obtained and a toner detection circuit 42 detects the shortage of the toner, an agitator 20 is driven by an agitator control circuit 44 so as to supply the toner 22 to a developing tank 16. When I<Is2 is obtained and the electrification amount of the toner is insufficient, a relay 46 is turned on, so that voltage is impressed on the blade 28 and charge is forcibly injected in the toner 22.
