Abstract: PURPOSE:To prevent excess torque by providing a stopper to block displacement in the clutch contact direction at the time of high speed of an engine on a clutch arm to control a clutch between the engine and a power take-off. CONSTITUTION:An engine 10 is operated by a throttle lever 16 and it drives an output shaft 22 of a power take-off 20. The power take-off 20 contains a clutch and intermits with a clutch arm 48. The clutch arm 48 is installed on the upper edge part of a support shaft 44, and its contact part 52 is provided on the outside of a bracket 40. A stopper 62 interlocks with a control arm 64, and at the time of low speed rotation, it oscillates upward and it is released from the contact part 52 of the clutch arm 48, and at the time of high speed rotation, the head edge descends and intrudes into an oscillation passage of the contact part 52. Accordingly, change-over of the clutch is not carried out, and it is possible to prevent excess torque from affecting on a power transmission system and the side of a working machine.

Duty control is made on an opening time of the valve 9 by means of a control circuit 20. Namely, from an output from an O2 sensor 14, it is discriminated whether an air-fuel ratio is either lean or rich as against a desired air-fuel ratio. When discriminated that it is lean, a reference valve opening time determined based on an operating condition is decreased by a first correction value, meanwhile, when discriminated that it is rich, a reference valve opening time is increased by a second correction value. When an air-fuel ratio is changed from rich to lean, a first correction value is widely changed only during the change, and when changed from lean to rich, a secondary correction value is changed only during the change.

Abstract: PURPOSE:To efficiently refine iridium by carrying out electrolysis while circulating an iridium solution containing chloride ions on a cathode chamber side and also performing filtration. CONSTITUTION:At the time of refining an Ir solution containing chloride ions by means of diaphragm electrolysis, an electrolytic cell is partitioned into an anode chamber and a cathode chamber by means of a diaphragm 1, and a hydrochloric acid solution of about 0.1N is added as an anolyte 4 to the anode chamber and an Ir solution of about 0.5N HCl containing noble metal impurities is added as a catholyte 5 to the cathode chamber.

IPC: G01N30/14
Filed: 1991-08-29
Abstract: PURPOSE:To adjust an apparatus in a stably operating state by sampling a certain amount of carrier gas and process sample and automating operation of two switch valves having four connection ports and three separation columns. CONSTITUTION:When a sample sampling valve is turned ON, its internal flow path is changed over, so that process sample in a measuring tube is separated through connection ports 3a, 3b of a switch valve 3 into components to be measured and unnecessary components at a separation column 4a. The components to be measured come through connection ports 5a, 5b of a switch valve 5 to a separation column 4c to be separated into respective components. If the switch valves 3, 5 are simultaneously turned ON at this time, the internal flow path changes from solid lines to broken lines, so that the unnecessary components remaining in the column 4a are carried oppositely to carrier gas and discharged through a restrictor 3g. On the other hand, a signal of a detector 6 is processed in an integration circuit and a control circuit 8 to have concentration, etc., of the components to be measured calculated, which is output as a concentration signal S2. An instruction signal S3 drives a sample sampling valve 2 and the switch valves 3, 5 via a valve driving circuit 9.

Title: Heat exchanger for fast breeder
Inventor: IWASAKI HIDEO
IPC: F28F9/00
Filed: 1982-12-16
Abstract: PURPOSE:To facilitate drainage in a simple way at low cost in the titled heat exchanger, by providing rings to the upper and the lower parts of the outer surface of an inner shell and the inner surface of an outer shell, alternately, and by fitting a thin ring which is transformed mainly by fluid force and can shut off a bypass flow, to at least one of the above-mentioned rings. CONSTITUTION:When sodium is injected into an outer shell 2 from the primary sodium nozzle, a thin ring 22, connected to a ring 21 on the inner surface of an outer shell by the fluid force, is transformed and contacted to the ring 20 on the outer surface of an inner shell, so as to press itself against the ring 20, then a bypass flow can be stopped. The thin ring 22 can serve as a self-tightening seal, by properly determining the distance between both rings 20 and 21, and the elasticity of a thin ring 22. The thin ring 22 contacts to the ring 20 on the outer surface of an inner shell so as to depress it when the fluid force is acted on the ring 22, while it separates from the ring 20 when the fluid force does not act on it. When sodium is drained, it can be drained by only stopping the supply of sodium to the shell.
