Title: Ceramic raw material, dephosphorizing agent and their production
Inventor: KAWAKATSU TAKESHI
IPC: C02F1/58
Filed: 1996-04-03
Abstract: PROBLEM TO BE SOLVED: To inexpensively dry water purification sludge which has been discarded and to effectively use it as ceramic raw materials and the like by dehydrating sludge generated in a water purifying process before heating and drying it with high temperature waste gas from a private electric generator running on natural gas. SOLUTION: Snice concentrated sludge obtained by concentrating sludge by a thickener contains about 90wt.% of water content, it is dehydrated to about 40-65wt.% of water content by a dehydrator. In a water purification plant, when an electric generator running on natural gas for supplying power on the premises is provided, high temperature waste gas is obtained with generation of electricity. Then, the high temperature gas is fed to above a multistage pneumatic dryer to heat sludge fed from below, allowing moisture to be removed and organic matter to be decomposed and burned, and a ceramic raw material of <=15% moisture content and <=3% organic matter content is obtained. The dehydrated, dried material thus obtained is formed of fine particles, but in the case it contains coarse particles, it is preferably screened prior to use.

Abstract: PURPOSE: To restrain a wondering phenomenon and improve linear stability. CONSTITUTION: A tread 5 is constituted of the first tread brought into contact with the ground in a flat road and the second tread which extends more outwards in the tire cross direction than the first tread and is brought into contact with the higher side of an inclined road surface 11 inclining to the tire axial direction. If a grounding width is taken as CW1 , a grounding length CL1 and rectangle ratio KR1 at the time of contact with the flat road under a specific inner pressure and a load of 70% of specific maximum load performance, the following relations are obtained: CL1 /CW1 <1.7, KR1 >0.7.  If the dimension in the tire axial direction between the longest part in the peripheral direction of the contact part and the contact end on the higher side of the inclined road surface is taken as MW when grounding is made at an angle 10 deg. of tire equatorial surface CL to the perpendicular line of the inclined road surface, the following relation is obtained: MW>0.15CW1 . It is thus possible to get over the inclined road surface smoothly by increasing camber thrust FC.

Title: Electronic component device
Inventor: SHIGA SHOJI
IPC: H01L23/50
Filed: 1997-04-01
Abstract: PROBLEM TO BE SOLVED: To suppress the production of solder bridges and realize the fine pitch of lead pins by a method, wherein outer leads of which a lead substrate is composed are covered with Pd at least on their surface parts soldered to a circuit board and the outer leads are covered with oxide films with thicknesses not less than a specified value at least on their side surfaces. SOLUTION: Outer leads 7 of which a lead substrate is composed are covered with Pd at least on their surface parts soldered to a circuit board. Further, oxide films with a thickness not less than 100Åare formed, at least on the side surfaces of the outer leads 7. As Pd which has good solder wettability is applied to the slodering surfaces of the lead substrate as described above, the lead substrate has superiod solderability. Further, as Pd hardly causes fusion reaction, excessive solder hardly adheres and, as the oxide films which have inferior solder wettability are formed on the side surfaces of outer leads 7, solder adhesion in the direction of lead pin arrangement is suppressed, so that the production of solder bridges can be suppressed.

Abstract: PURPOSE:To obtain such a state that has no microscopic disturbance in orientation and to improve the display quality for all visual angles including the display quality for the front view by forming a discotic nematic phase in a layer containing a discotic liquid crystal. CONSTITUTION:A thin film of a discotic liquid crystal is formed by applying it on a substrate. The thin film is rapidly heated to the discotic nematic phase temp. and then rapidly cooled to form the glass state of the discotic nematic phase. This discotic liquid crystal shows optically negative uniaxial property by itself, so that the optical anisotropic material containing the discotic liquid crystal with its optical axis tilted from the normal direction is effective to improve the visual angle characteristics of a TN liquid crystal cell. A specified discotic liquid crystal has such properties that when the discotic liquid crystal phase is solidified as in the oriented state, its structure can be stably maintained at temp. lower than the discotic liquid crystal phase-solid phase transition temp. Thus, the obtd. optical anisotropic material is thermally stable.

Title: Ac vehicle
Inventor: TAKAHARA HIDEAKI
IPC: B60L9/12
Filed: 1978-07-07
Abstract: PURPOSE: To reduce induction troubles during control, by diviiding the DC circuit of an electric vehicle into numerous groups and geometrically unbalancing the order of use of windings of a transformer of the vehicle.  
     CONSTITUTION: Two upper secondary windings u11-v11, u21-v21 of the main transformer of the AC vehicle are used first. Two intermediate secondary windings u12-v12, u22-v22 of the transformer are used second. Two lower secondary windings u13-v13, u23-v23 of the transformer are used third. Since these windings are not symmetrically located, there is a difference in the leakage impedance in the intermediate stage of thyristor turn-on control. When the control is finished and the full voltage is applied, the difference disappears. As a result, the gradient of current rising at the angle of thyristor commutation overlap decreases. The induction troubles are thus reduced.

Abstract: PURPOSE:To reduce parts and increase safety by transferring both constant- voltage and constant-current signals to a primary side by one photo-coupler. CONSTITUTION:A constant-voltage detection is performed by a shunt regulator 9 connected in series with a photo-coupler 10 and is transferred to a primary side by said photo-coupler 10. In this case, an output end of operational amplifier 11 is connected with a junction of the photo-coupler 10 and the shunt regulator 9 via diode 14. Thus, a constant-current detection by a current sensing resistor 12 connected within a load circuit is performed, when the operational amplifier 11 is operated by an increase of load current to lower its output voltage to turn ON the diode 14 and the photo-coupler 10 is made to perform an operation corresponding to the constant-current value. As a result, both constant-voltage and constant-current detections can be transferred to a primary side by one photo-coupler 10.
