Title: Method and device for automatic adjustment of sludge concentration in sewage treating chamber
Inventor: MIHASHI KAORU
IPC: C02F3/12
Filed: 1987-04-13
Abstract: PURPOSE:To maintain specified sludge microorganism by withdrawing sludge from a sewage treating chamber and storing the same in a sludge concn. adjusting chamber when the propagation rate of the sludge microorganisms in said chamber is high and replenishing the sludge into the sewage treating chamber from the sludge concn. adjusting chamber when the concn. is decreased by self digestion. CONSTITUTION:A sludge transferring mechanism 6 is operated when a transmission type optical sensor 14 mounted in the sewage treating chamber 1 or a circulation circuit 2 for the treating water decides that the sludge concn. in the chamber 1 is higher than the prescribed concn. The high-concn. sludge in the chamber 1 is then transferred into the sludge concn. adjusting chamber 5 by the operation of the mechanism 6 and the supernatant in the chamber 5 is made to flow over said chamber into the chamber 1 to dilute the sludge in the chamber 1 to the lower concn. A sludge returning mechanism 9 is operated when the above-mentioned sensor decides that the sludge concn. in the chamber 1 is lower than the prescribed concn. The settled sludge in the chamber 5 is returned into the chamber 1 by the operation of the mechanism 9 to increase the concn. of the sludge in the chamber 1. As a result, the always specified sludge microorganism are maintained in the treating water and the amt. of the excess sludge is decreased.

IPC: G04B37/22
Filed: 1986-04-21
Abstract: PURPOSE:To plate a plastic watchcase without causing cracking by fixing plastic glass different from the plastics of the case in chemical properties in the case and by plating only the case. CONSTITUTION:A plastic watchcase 1 is made of ABS resin, plastic glass 2 is made of polycarbonate resin and the case 1 is plated. At this time, the glass 2 is fixed in the case 1 by forming a joined face 6 by ultrasonic melt bonding to keep airtightness without causing a creep phenomenon in the case 1. Only the ABS resin is then activated by etching with a treating soln. and only the ABS resin case 1 is chemically plated. The polycarbonate resin glass 2 is not chemically etched at all. The chemically plated case 1 is subjected to final finish electroplating. Thus, plating is carried out without cracking the resulting plated layer 5.

IPC: B60P1/273
Filed: 1980-07-04
Abstract: PURPOSE: To assure the strength of the bed of a dump truck, by rigidly lock up its side flap and tail flap on struts.  
     CONSTITUTION: When a means 16 for opening and closing a tail flap 9 is closed and a mounting shaft 12 released from an upper fitting metal member 10 on the top of a strut 5, the flap 9 swings down backward centering a carrying metal member 13 pinched between an engaging claw 14 and a carrying member 15. As a result, the rear of a bed 1 is opened. In that case, the rear end of a side flap 3 remains engaged with the strut 5 by an engaging metal member 11 in a safe state not to open outward. To swing only the side flap 3 sidewards, the engaging metal member 11 for the flap 3 and the strut 5 is released to let the flap 3 swing sidewards centering hinges 4. In that case, the tail flap 9 never turns over backward because there is a distance between the point of the strut 5 pivotally coupled to a bracket 6 and the hinges 8 and the point of engagement of the flap 9 with the carrying metal member 13 by the opening and closing means 16.

Filed: 1989-04-12
Abstract: PURPOSE:To permit restart even after the sharp stop due to the ascent inertial traveling by changing the speed ratio of a continuously variable transmission to the deceleration speed side by a control means when the ascent inertial traveling of a vehicle is judged. CONSTITUTION:An electronic controller 460 receives the signals of output shaft revolution sensors 464 and 466, car speed sensor 462, throttle opening degree sensor 468, shift position sensor 470, brake switch 472, etc., and judges the ascent inertial traveling of a vehicle. Solenoid valves 330 and 346 are duty- controlled, and the speed ratio of a CVT 14 is changed to the deceleration speed side through a hydraulic control circuit and hydraulic actuators 54 and 56. Therefore, even if a brake is not operated, the speed ratio changes to the deceleration speed side in relation to the sharp stop of the vehicle. Thus, after the sharp stop due to the ascent inertial traveling, the restart on the ascent is enabled sufficiently.
