Title: Flocculated floc storing and recovering device and flocculating filter and method of catching and recovering flocculated floc
Inventor: MURATE TAKAHIRO
IPC: C02F1/52
Filed: 1998-12-25
Abstract: PROBLEM TO BE SOLVED: To improve catching efficiency of flocculated flocs in the device in which treated water is passed through a tank filter provided with a filter bed packed with filter medium in a upflow by installing a partition net for catching and storing flocculated flocs in the lower position of the tank filter and installing a floc storage chamber on the upper part side thereof. SOLUTION: When in mid-way of an inflow pipe 5 of raw water, secondary treated water to which a flocculant from a flocculant tank 8 has been added is caused to flow in a flocculating tank A, by aeration from a diffuser 10, it is subjected to bubbling to uniformly agitate and mix it. This liquid mixture is subjected to flocculation by gradually taking in SS in the secondary treated water and phosphorus components in the treated water in a process in which it is caused to flow down in the flocculating tank A. The liquid mixture containing flocculated flocs X is caused to flow in a bottom chamber B1 of the tank filter B and is turned in an upflow and is raised, and when it is passed through the partition net 13, flocs are caught. When a part thereof is floated in a floc chamber B2, it is flocculated and turned into floc lumps, which are precipitated and stored on the partition net 13.

Title: Reinforcing member, reinforcing structure for ic chip mounting part and assembly method for ic card and reinforcing member
Inventor: KAMIYA KENJI
IPC: G06K19/077
Filed: 1998-12-25
Abstract: PROBLEM TO BE SOLVED: To provide a reinforcing structure for expelling residual air to be the cause of weakening a reinforcing effect in the reinforcing structure of an IC chip mounting part to the utmost. SOLUTION: A groove part 11 provided in this reinforcing member 10 is oppositely arranged on the side of reinforcing resin 7. When the reinforcing member has no groove part 11 and has a smooth surface, in the case that a gap 20 is generated between the reinforcing member 10 and the reinforcing resin 7, when the gap 20 is not communicated with the outside at all, even though pressurizing is performed and the residual air is forced to be expelled to the outside, the reinforcing resin 7 of high viscosity hardly flows and the residual air is present. To the contrary, when the reinforcing member 10 is provided with the groove part 11, even when the reinforcing member 10 and the reinforcing resin 7 are tightly adhered at the part other than the groove part 11, the gap 20 is communicated with the outside at the groove part 11.  Thus, even the reinforcing resin 7 of the high viscosity relatively easily flows, the residual air inside the gap 20 expelled through the groove part 11 to the outside and the possibility of eliminating the residual air becomes high as a result.

Title: Friction coefficient peak estimating device and antiskid control device with the estimating device
Inventor: KATO HIRAHISA
IPC: B60T8/172
Filed: 1998-12-25
Abstract: PROBLEM TO BE SOLVED: To reliably estimate a peak and properly control braking force by estimating that the friction coefficient in a road surface friction coefficient-slip ratio characteristic reaches the peak when the wheel acceleration detected by a wheel acceleration detecting means becomes lower than the body acceleration detected by a body acceleration detecting means by the prescribed difference or above. SOLUTION: If the wheel speed Vw1 shown by a solid line becomes the reference speed Vtb or below at time t0 and the wheel acceleration DVw1 becomes the prescribed reference value DVs0-α a or below at time t1, the friction coefficient is considered to reach a peak. If the wheel speed Vw2 shown by a broken line becomes the reference speed Vtb or below at time t0 and the wheel acceleration DVw2 becomes the prescribed reference value DVs0-α or below at time t2, the friction coefficient is considered to reach the peak.  The timing when a brake action is taken to a vehicle fitted with studless tires and the wheel acceleration DVw2 becomes the reference value DVs0-α or below is delayed than the timing when the wheel acceleration DVw1 becomes the reference value DVs0-α or below, this is due to the nature of the studless tires and is inevitable, however the peak can be reliably specified.

IPC: H01L21/768
Filed: 1990-12-14
Abstract: PURPOSE:To provide a wide air bridge wiring with low resistance by completely etching resist away from under a bridge plate. CONSTITUTION:A bridge plate 3 is provided with holes 4 through which etchant passes at the time of etching. When a photoresist film 18 is wet-etched after the formation of an air bridge wiring 1, therefore, the etchant flows under the bridge plate 3 from the sides of the air bridge wiring as well as from the upper surface of the bridge plate through the holes 4.
