Title: Travel controller
Inventor: OCHI TATSUJI
IPC: F16H61/18
Filed: 1991-11-08
Abstract: PURPOSE:To obtain a travel controller, equipped with a frequency sensing means for sensing the practice of decelerating operation with an actuator prescribed times or more and capable of making the actuator perform accelerating operation interlocking with the sensing and preventing a hunting phenomenon from occurring. CONSTITUTION:An infinite variable speed device 2 interposingly installed in a machine body travel driving system is constructed so as to enable speed changing operation by driving with an actuator 10. The travel controller is equipped with a controlling means for performing control so as to make the set value of a speed setter (PM2) coincide with the speed provided with the actuator 10 and an automatic speed change controlling means (A) for making the actuator perform decelerating operation to the low speed side when the speed of the engine 1 is reduced to the first set value or below and making the actuator perform accelerating operation to the high speed side when the engine speed is returned to the second set value higher than that of the first set value. When a decelerating operation frequency sensing means (B) for sensing the practice of the decelerating operation with the actuator 10 prescribed times or more becomes in a sensing state, the actuator 10 is made to perform the accelerating operation to a lower changed speed than that of the set speed fixed with the speed setter (PM2).

Abstract: PURPOSE:To prevent short circuits between wirings due to the formation of metal chips by performing a circuit test after the formation of a first protecting film. CONSTITUTION:The entire surface of an integrated circuit is covered with a first protecting film 32. The first protecting film 32 which is located on a pad part 26 and a fuse for a redundant circuit is selectively removed. A circuit test is performed by using a pad part 21. A second protecting film 33 is formed on the upper part of the first protecting film 32. At least the upper parts of the fuse part 21 and the pad part 26 are covered, and the second protecting film 33 is selectively removed. Thus the surface of the pad part 26 is exposed.

Title: Oil-water separator
Inventor: TAKAKURA YOSHIAKI
IPC: B01D17/025
Filed: 1990-10-29
Abstract: PURPOSE:To constitute the title separator in a relatively small installation area by a prefabricated assembling system or unification by mounting a receiving tank which receives water to be treated from the upper opening thereof a plurality of settling tanks, an oil collecting tank taking in floated oil as an overflow stream, a circulating pump means refluxing oil and water to the receiving tank and a drain means. CONSTITUTION:The water to be treated of an oil-water mixture flowing in a receiving tank 10 from a culvert through the connection part 1a on the inlet side thereof flows in the surface oil layer of the receiving tank 10. The water to be treated flowing in the receiving tank 10 involves the oil in the oil layer to flow down and flows in the first settling tank 11 from the surface part thereof through two rising pipes 15 provided in the width direction of said tank 11 in the state mixed with a slight amount of oil particles while oil particles are floated by slight settling effect. Since the first settling tank receives the flow of the water to be treated from two rising pipes 15 in the vicinity of the surface thereof, turblent flow is reduced and, therefore, the settled oil particles in the water to be treated are effectively floated. The treated water reduced in the content of oil particles of the lower layer flows in the second settling tank 12 from below. Sufficient buoyancy effect is exerted on the oil particles in the water to be treated flowing in the second settling tank 12 to float the oil particles and the oil component remaining in the surface layer part is almost floated.
