Title: Flocculant of inorganic component
Inventor: FUNAYAMA MITSUO
IPC: B01D21/01
Filed: 1996-06-10
Abstract: PROBLEM TO BE SOLVED: To clarify a suspension and recover useful materials from coagulating fine granular substance by collecting fine granular substance suspending in water. SOLUTION: Powders consisting of 50-60wt.% alumina, 5-10wt.% calcia, 5-10wt.% silica and 5-10wt.% sodium oxide (in terms of oxides respectively) are used as a coagulant. When the coagulant is fed into water and mixed, it reacts with water instantaneously to form hydroxides, resulting in no requirement for pH pre-adjustment because of capability for a wide pH range of waste water to be treated except extreme cases; when fed into waste water and intensely mixed, suspended granular substance in the waste water are instantaneously agglomerated to form flock which settles with separation from supernatant. Because the resultant flock is similar to fish egg, large granules and water trapped inside the flock moves to surfaces through granules, pressure dewatering is easily possible.  Even solar drying is possible, because remaining water moves to surfaces from dewatered sludge, being dried by saturation with ambient moisture. After drying useful materials are recovered from the flock.

Title: Logic circuit
Inventor: OBATA HIROYUKI
IPC: H03K19/0948
Filed: 1986-06-23
Abstract: PURPOSE:To eliminate the power voltage dependance of a threshold value by interposing one conduction type depletion MOS-FET of having a large ON- resistance whose gate is connected to an output terminal in series between the said output terminal and the other conduction type MOS-FET constituting a CMOS logic circuit. CONSTITUTION:Since the on-resistance of a P-channel enhancement MOSFETQ1 of a CMOS inverter is sufficiently smaller than the on-resistance of an N-channel depletion MOSFETQ3 to be inserted, the threshold voltage depends on the threshold voltage of the N-channel depletion MOSFETQ3 and the N-channel enhancement MOSFETQ2, but the threshold voltage of the depletion MOSFETQ3 is independent of the power voltage, then the logical threshold voltage is independent of the power voltage. Further, the power consumption is less.

Title: Treatment of nitrogen oxides and nitrogen oxides treating material
Inventor: SEKI KENJI
IPC: B01D53/81
Filed: 1997-06-05
Abstract: PROBLEM TO BE SOLVED: To remove NOx to a low concn. with a high efficiency by adsorbing NOx on an org. metallic complex having a one- or three-dimensional channel structure as an adsorbent. SOLUTION: An org. metallic complex having a one- or three-dimensional channel structure is used as an adsorbent. This complex is formed from a dicarboxylic acid having two carboxyl groups at positions which are symmetric with respect to a point in one molecule and a metallic ion, and it is, e.g. copper terephthalate, copper fumarate or copper 1,4-trans-cyclohexanedicarboxylate. A gas treating device 1 has a chamber 3 housing the adsorbent 2, a gas feeding path 4 capable of freely suspending the feed of gas to be treated and recovery paths 5, 6 capable of selectively recovering gas discharged from the chamber 3. Since the adsorbent adsorbs NOx with relatively high selectivity and has high adsorbing ability, the concn. of NOx can be reduced to a low level.

Abstract: PURPOSE:To easily release a locked state in an impeller lock phenomenon by fixing the base end of a stationary shaft in the center of a partition plate, and forming a wave-like circular rib around the fixed portion of the stationary shaft of the partition plate. CONSTITUTION:A nonmagnetic disk-like partition plate 15 is fixed under a casing 1 by a stationary screw 20. A wave-like circular rib 21 is formed around the center where the end of a stationary shaft 8 of the partition plate 15 is fixed. Accordingly, a diaphragm-type spring effect in an axial direction of the stationary shaft 8 is applied to the partition plate 15. When a pump is left in an inoperative state for a long time, a bearing 11 is brought into film contact with a thrust washer 14. In this case, a light impact by a hammer or the like is exerted on the upper end of the stationary shaft 8 in the axial direction so that the stationary shaft 8 is operated in such a manner as to set a clearance (g) at 0. And further, the thrust washer 14 and the bearing 11 are moved in a separating direction so that the movement is transmitted to the partition plate 15. The partition plate 15 exerts vibration on the stationary shaft 8 in the axial direction with reaction, thus securely separating a fixed portion.

Title: Control method of gas flow rate at vapor phase epitaxial growth apparatus
Inventor: MARUYAMA KENJI
IPC: H01L21/365
Filed: 1990-06-05
Abstract: PURPOSE:To easily and surely control a prescribed gas flow rate by a method wherein a gas flow rate is controlled by using a plurality of control valves other than a specific valve and this operation is repeated after that. CONSTITUTION:Values of flowmeters 5A to 5D are taken into a control device 21 ; the values are compared with a set value. When the values coincide with the set value, individual flow- rate control valves 6A to 6D are set as they are. When the value of the flowmeter 5A out of the flowmeters 5A to 5D deviates from the set value, the opening and shutting degree of the flow-rate control valves 6B, 6C, 6D connected to the flowmeters 5B, 5C, 5D is adjusted in such a way that the respective values of the flowmeters 5B, 5C, 5D other than the flowmeter 5A coincide with the set value. After the flow rate has been adjusted and when the value of the flowmeter 5B out of the flowmeters 5A to 5D deviates most from the set value, the opening and shutting degree of the valves 6A, 6C, 6D connected to the individual flowmeters is adjusted again in such a way that the respective values of the flowmeters 5A, 5C, 5D other than the flowmeter 5B coincide with the set value. When the control valves are controlled in this manner, the flow rate of all gas introduction tubes branched into a plurality of tubes can collectively be controlled. As a result, the range of the opening and shutting degree of the flow-rate control valves can widely be set and the flow rate can surely be set to a desired set value.
