Title: Desulfurizing method using pressurized water
Inventor: MATSUOKA HIROO
IPC: B01D53/48
Filed: 1985-03-08
Abstract: PURPOSE:To remove H2S and SO2 in the simple treatment by sending both a gas contg. H2S and a gas contg. SO2 simultaneously and continuously into the pressurized water free form an additive and allowing both to perform the Claus reaction. CONSTITUTION:Both a gas contg. H2S and a gas contg. SO2 are sent into a reactor 1 charged with water free from an additive through the lines 2, 3 and the soln. in bubbled in the pressurization. The Claus reaction is made active together with passage of time and elemental sulfur is produced and made slurry. The slurry of sulfur is sent to a separator 5 through a line 4 to separate it into water and sulfur and sulfur is discharged through a line 6 and water after the separation is circulated to the reactor 1 through a line 7. After the desulfu rized gas removed with the large parts of H2S and SO2 is sent to a cooler 11 via a line 10 to condense and separate the accompanied steam, it is washed with water in a purification tower 13 to remove the nonreacted H2S and SO2 and discharged or recovered through a line 14.

Title: Partition
Inventor: OKUDAIRA YUZO
IPC: G10K11/178
Filed: 1989-02-23
Abstract: PURPOSE:To reduce noises by making the sound which is generated by a speaker and a noise which is propagated round from the top surface or flank of the partition interfere with each other in a specific area. CONSTITUTION:A microphone 2 fitted to a partition main body 1 detects a diffracted sound 8 arriving from a noise source 6. Signal information on the detected diffracted sound 8 is inputted to a control circuit 3 which calculates what wound wave needs to be generated by the speaker 5 so as to eliminate the diffracted sound 8 in the specific area 7 by interference effect. The signal calculated by the control circuit 3 is sent to an amplifier 4 and radiated by the speaker 5 as a sound wave 9. The radiated sound wave 9 interferes with the diffracted sound 8 in the specific area 7. Consequently, the noises in the specific area 7 are reduced.

IPC: D06F58/28
Filed: 1989-02-22
Abstract: PURPOSE:To precisely judge the sorts of cloth to be dried without troubling a user and decrease the sorts of switch input by providing a judgment means by which the sorts of cloth to be dried are judged according to a ratio of the detected weight result of a weight detection means to the contact frequency detected result of a contact frequency detector. CONSTITUTION:When an electrode 9 is equipped in a rotary drum 2 so that the object to be dried comes in contact with the electrode 9, the contact frequency to the electrode varies depending upon the sorts of cloth to be dried, cotton or synthetics, assuming that the cloth to be dried has the same weight (including moisture weight). The weight of the cloth to be dried is detected by a weight detection means 36, and the contact frequency of the cloth to be dried is detected by a contact frequency detection means 29. The sorts of cloth to be dried are judged by a judgment means of a microcomputer 26 according to the ratio of the two detected results. Therefore, the judged result conforming to the sorts of the cloth can be precisely obtained without troubling a user.

When "Kinjo" in Kana is input, since the conversion unit word including Kanji "Kinjo" is displayed, "Kinjo" in Chinese character is selected with the YES key 28. If the reading of "Kinjo" in Chinese character is not known, the key 32 is set to work, Kanji side and the key 33 is set to indirect position. Then, the reading of word, Chinese character "Kin" and "jo", i.e., "Chikai" and "Tokoro" in Kana is input, the Kanji "Kinjo" can be obtained. Thus, since the operator can save the labor to discover correct reading  of the Kanji dictionary, the operation ability of conversion processing can be increased.

Title: Formation of roots-type pump rotor
Inventor: NODA TAKASHI
IPC: F04C18/18
Filed: 1988-02-26
Abstract: PURPOSE:To make a rotor very larger in cohesion as well as to reduce its cost, by heating a rotor material up to melting temperature of liquid crystal polyester resin and then forming this resin by means of injection molding, then sticking it closely to the surface. CONSTITUTION:At the time of forming a Roots-type pump rotor by means of resination, a rotor material 1, whose circumference is of cocoon-form, consisting of an aluminum alloy is used as an insert member. Minute holes 10a, 10b are installed on an aluminum surface. If the aluminum material is heated up to 280 deg.C, minute holes 12a, 12b are expanded. Since the rotor material is being heated, resin is in no case solidified and gets into each innermost recess of these minute holes 12a, 12b. If temperature goes down, the resin in the hole is contracted because of aluminum contraction, and minute holes 14a, 14b are also contracted, so that the resin and the aluminum are strongly bound together. Thus, such a rotor as very large in cohesion is securable and, what is more, it is formable inexpensively in terms of manufacturing cost.
