Title: Brake hydraulic pressure controlling device for vehicle
Inventor: NAKANO TOSHIHIRO
IPC: B60T8/44
Filed: 1996-08-29
Abstract: PROBLEM TO BE SOLVED: To provide a brake hydraulic pressure controlling device for vehicle which is advantageous in securing pressurizing stroke of a piston of a master cylinder. SOLUTION: When a brake hydraulic pressure of wheel cylinders 31 and 32 is excessive, pressure of the wheel cylinders 31 and 32 for braking wheels is reduced. The brake fluid whose pressure was reduced flows into a first reservoir chamber 23 via a first opening/closing valve 81 in the open state, presses a flange part and makes a piston 11 retreat in the direction opposite to the pressurizing direction, that is, X2 direction. At this time, a second opening/ closing valve 85 is closed.

Title: Drive
Inventor: BURATSUDOREI ORIBAA RIIDO
IPC: F16H1/36
Filed: 1988-09-16
Abstract: PURPOSE: To improve power efficiency against different load conditions to forward propulsion and steering by providing a pair of independently controllable power sources or motors as a main motor power in a drive system of track-laying vehicles. CONSTITUTION: Separately independently controllable motors M1, M2 are output through shafts 10, 22, pinion gears 14, 24, and planetary gears 20, 30 to right and left output shafts 32, 34 to drive respective endless tracks by a sprocket. When a first range brake B1 is released and a second range clutch CII is put off, the motors are in an idling condition. When the brake B1 is engaged, the motors are developed to a first constant speed range, and when the brake B1 is released and the clutch CII is put, the motors are developed to a second speed range. When the motors M1, M2 reversely rotate, the motors are developed to reverse propulsion. Steering operation increases output speed of one motor, and decreases the same output speed of the other motor.  Thereby the drive system can effectively use driving power or the motors against load conditions of the forward propulsion and the steering.

Title: Method and apparatus for treating organochlorine compound-containing sewage
Inventor: TORII HISAMICHI
IPC: C02F9/00
Filed: 1999-08-17
Abstract: PROBLEM TO BE SOLVED: To efficiently and certainly treat an organochlorine compd. in sewage to detoxify the same. SOLUTION: Sewage containing an organochlorine compd. is allowed to flow in an oxidizing treatment tank 1 from an inflow pipe 3 while hydrogen peroxide is appropriately added to the sewage and aerated by ozone while irradiated with ultraviolet rays. Hydroxyl radicals are formed by the addition of hydrogen peroxide, the irradiation with ultraviolet rays and a photocatalyst to oxidize and decompose the origanochlorine compd. to a hydrophilic intermediate byproduct. The intermediate byproduct is immediately hydrolized to a haloacetic acid by the water of sewage. The sewage thus treated is allowed to flow in a biological activated carbon tank 11 through an outflow pipe 10 while phosphorus or nitrogen is appropriately added to the sewage to be brought into contact with activated carbon to adsorb the haloacetic acid.  Adsorbed haloacetic acid is decomposed by microorganisms supported on activated carbon. Since even haloacetic acid requiring time in decomposition is once adsorbed to be microbially decomposed, it does not flow out in an undecomposed state and can be certainly treated microbially even in low concn. without lowering adsorbing capacity.
