Abstract: PURPOSE:To increase the regeneration efficiency of an adsorbent regenerating device for dehumidifying equipment using adsorbents to perform energy saving in a regenerating process. CONSTITUTION:An adsorbent 1, a heating source 2 installed on the upstream side of the adsorbent 1, a heat exchanger 3 incorporated into the adsorbent 1, a fan 4 to deliver air to the adsorbent 1, and an air duct 5 enclosing them are provided. When an adsorbent regenerating device thus constituted enters the regeneration process, the heating source 2 is operated. The heating source 2 makes air delivered by the fan 3 hot air to transfer heat to the heat exchanger 3 which uniformly heats the whole adsorbent 1. On the other hand, the adsorbent 1 near the heating source 2 is heated by receiving radiation heat from the heating source 2. By heating of the adsorbent 1 by the hot air and the radiation heat, the adsorbent 1 is uniformly heated, causing the moisture in the adsorbent 1 to be uniformly removed from the adsorbent 1. Thus, regeneration efficiency is increased and energy saving in the regeneration process is performed.

Filed: 1994-07-06
Abstract: PURPOSE:To eliminate a flexible hose in a reduced pressure chamber and supply the fluid to a cassette elevator exactly by circulating cooled water in a channel of the cassette elevator through outdoor fluid supply pipes, a joint, and indoor fluid supply pipes. CONSTITUTION:Cooled water is circulated in a channel 11 of a cassette elevator through outdoor fluid supply pipes 17, 18, a joint 16, and indoor fluid supply pipes 12, 13. The indoor fluid supply pipes 12, 13 and the joint 16 go up and down along the up and down operation of the cassette elevator 4 with a bellows being extended and contracted, so they do not hinder the up and down operation of the cassette elevator 4. A hole 14 formed in a wall 2 is airtightly closed by the bellows 21 and therefore the degree of vacuum in a reduced pressure chamber 1 does not decrease. Furthermore, there is no source of dust such as a flexible hose in the reduced pressure chamber 1 including the inside of the bellows 21 and so the inside of the reduced pressure chamber 1 is kept clean and is not damaged and thereby the fluid can be supplied to the cassette elevator accurately.

Abstract: PURPOSE:To prevent the adhesion to a semiconductor wafer to dust generating when the semiconductor wafer to be heat-treated is inserted into or taken out from a reaction pipe by a method wherein the chamber, in which the semiconductor wafer to be heat-treated is inserted or taken out, is detachably provided in the reaction pipe, and an inlet hole and an outlet hole of gas are formed on the end face of the chamber. CONSTITUTION:When gas is fed from a pipe 23 while it is being heated up by a heater 22, the gas penetrates into a chamber from the inlet holes 16 and 17 perforated in a chamber 19, and the gas is exhausted from an outlet hole 18. When a heat treatment is finished, the chamber 19 is pulled out from a reaction pipe 21, the upper half part 12 of the chamber is disconnected from the lower half part 11, and a semiconductor wafer 13 is taken out. When the semiconductor wafer 13 is inserted into or taken out from the reaction pipe, as the semiconductor wafer is housed in the chamber 19, almost no dust is intruded into the chamber, and the adhesion of dust on the semiconductor wafer can be prevented. Besides, as the quartz with which the chamber 19 is constituted has low coefficient of thermal conductivity, the semiconductor wafer 13 can be heated up or cooled down slowly.

Title: Air blower having once-through fan and air conditioner
Inventor: TAKADA YOSHIHIRO
IPC: F24F1/00
Filed: 1990-06-15
Abstract: PURPOSE:To prevent an inverse flow near a side plate, cyclic irregular sound and occurrence of vane sound by a method wherein a stabilizer is projected and mounted within a specified range starting from both side plates of an once-through fan toward its central part in a suction flow passage of the once-through fan in such a relation as the stabilizer may be directed between an axis of a vane wheel and a center of turbulence generated by the once-through fan. CONSTITUTION:A stabilizer 9 is projected and mounted within a suction flow passage enclosed by a heat exchanger 4 and a suction casing 8a from a side plate 15 of an once-through fan 11 toward a central part thereof. It is assumed that an outer diameter of a vane wheel of the once-through fan 11 is defined as D and its length L satisfies a relation of L/D<=2.5. Under this condition, irregular sound can be positively prevented even if a flow resistance at the suction side is high. In addition, even if a turbulence position is stabilized and clogging occurs in a filter, no irregular sound is generated. In addition, its orientation is set in such a way as it occupies between an axis 11a of the once-through fan 11 and a center 12 of the turbulence, thereby a flow line of air along the stabilizer smoothly flows along a direction of the vane of the once- through fan.

Abstract: PURPOSE:To prevent the sticking of an evaporated material to a quartz tube near a  hole and monitor the interior of a growing furnace thoroughly, by passing an atmospheric gas through a larger clearance between a furnace for growing a single crystal  and a quartz tube provided around the furnace at the position of the hole of the furnace than that at other positions. CONSTITUTION:A transparent quartz tube 1 is provided around a furnace for growing  a single crystal having a noble metallic crucible 3, and a high-frequency heating coil  12 is provided around the quartz tube 1 to grow a single crystal of a highly volatile  substance, e.g. tellurium dioxide. In the process, a clearance 13 between the outer peripheral surface of the furnace and the inner peripheral surface of the quartz tube 1 at  the position of a hole 8 at the side of the furnace is set larger than at other positions.  An atmospheric gas fed from the upper inlet 10 in the growing is passed through the clearance 13 between the outer peripheral surface of the furnace and the inner peripheral surface of the quartz tube 1 while containing the evaporated substance and then  discharged from the bottom outlet 11 and partially introduced from the hole 8 into the  interior of the furnace. The large clearance 13 near the hole 8 permits the increase in  the flow rate of the atmospheric gas flowing into the hole 8, and the sticking of the  fine evaporated particles to the quartz tube 1 is prevented. Thus, the interior of the furnace for growing the single crystal can be observed in good conditions.
