Abstract: A filtration device has a primary conveyer tank which is equipped with a first conveyer, a primary drum filter which rotates inside the primary conveyer tank, a secondary conveyer tank which is equipped with a second conveyer and a secondary drum filter which rotates inside the secondary conveyer tank. Liquid in the primary conveyer tank passes through a first opening to flow into the secondary conveyer tank. Clean liquid flowing into a first clean tank is supplied to a low-pressure-side supply system by a first pump. Super-clean liquid having been filtered by the secondary drum filter passes through a second opening to flow into a second clean tank, and then is supplied to a high-pressure-side supply system by a second pump.

Abstract: A drive shaft with direct-mounted sprockets is arranged in a chain drive unit. The drive shaft includes a shaft body, a pair of metal plate sprockets, and first padding portions and second padding portions formed of weld beads. The first padding portions are formed such that their positions are changed to alternate with each other in a circumferential direction of the shaft body. The second padding portions are formed such that their positions are changed to alternate with each other in the circumferential direction of the shaft body. A torque input to the shaft body is transmitted to the metal plate sprockets via the padding portions.

Abstract: A paint booth is provided with a booth body and a purifier. The purifier is provided with a water tank, water rope formation mechanism, sludge removal mechanism, exhaust mechanism, barrier member, inclined plate, and windshield plate. Water falling from nozzles of a water case forms water ropes. The inclined plate has a water receiving surface sloping forwardly down from the barrier member toward a water surface of the water tank. A lower end of the windshield plate is in contact with water in the water tank. An airflow reversal section is formed between a lower end of the inclined plate and the water surface. Air directed downward from an airflow inlet is turned upward at the airflow reversal section and directed to an exhaust chamber through air circulation sections.

Abstract: A temperature detection device is connected to a temperature sensor, and includes two resistors, a transistor and a microcomputer. The temperature sensor is connected to ground. The resistors are connected in series between the temperature sensor and a power supply line. The transistor is connected to the resistor, which is at the power supply line side. The microcomputer switches over a characteristic of a sensor voltage, which is developed at a junction between the resistor and the temperature sensor, to a first characteristic and a second characteristic by switching over the transistor to an on-state and an off-state. The microcomputer calculates a temperature based on the sensor voltage. When the transistor is in the on-state, the microcomputer detects a voltage developed at a low-potential side output terminal of the transistor and calculates the temperature based on the transistor output voltage and the sensor voltage.

Abstract: A contaminated fluid recovery apparatus includes a sludge removal mechanism having a dirty tank, a conveyor, and a magnetic drum which is arranged in the fluid circulating section. The contaminated fluid recovery apparatus is provided with an overflow tank. The overflow tank has a function to keep a fluid surface of the dirty tank in a position higher than the fluid circulating section and the magnetic drum. The magnetic drum is located horizontally between a lower portion and an upper portion of the conveyor. The conveyor scrapes out chips deposited on a bottom portion of the dirty tank toward an exit section. A scraping member, which is in contact with the magnetic drum, drops sludge attracted to the magnetic drum toward the lower portion of the conveyor.

Abstract: A cyclone-type separator comprises a hollow cylindrical main body in to which liquid containing foreign matter is introduced, a clean room provided in an upper end of the main body, a communication pipe which connects the clean room to an interior of the main body, and a porous separating pipe arranged in the clean room. As the liquid swirls in the main body, an eddy stream is generated. A columnar air layer and a clean liquid layer are formed, both aligned with the centerline of the eddy stream. The air layer and the liquid layer are guided via the communication pipe into the separating pipe. At the bottom of the clean room, there are provided a first reservoir for storing the liquid coming through the separating pipe, a second reservoir for storing the liquid flowing from the first reservoir, and a coolant outlet port for discharging the clean liquid.
