Title: Leakage detecting device of blast furnace tuyere cooling water
Inventor: KATAGIRI HIDEAKI
IPC: C21B7/10
Filed: 1978-06-27
Abstract: PURPOSE:To improve the detection accuracy of leakage of cooling water by providing a feed  water flow rate detecting header and a discharge water detecting header as well as a pair of  flowmeters to the apparatus and measuring the differential flow rates between multiple tuyeres  and feed and discharge water pipelines  corresponding to these tuyeres. CONSTITUTION:At the measuring of a tuypere 8, the water supply side 3-way automatic ball  valve 4 and discharge water side 3-way automatic ball valve 5 are changed over to change the  cooling water channel to the B direction by a sequence unit 11. The cooling water flows from the  feed water side of a flowmeter 7 to a feed water flow rate detecting head 2, from where it flows in  the B direction of the ball valve 4 and enters the tuyere 8. This waste cooling water flows through  the ball valve 5 in the B direction, enters a waste water flow rate detecting header 3 and enters a tuyere discharge water trough 9 from the discharge water side of the flowmeter 7. This operation  is performed in the order of the tuyeres 8, 8', 8''. A calibration channel wherein the cooling water  flows from the flowmeter 7 into the feed water flow rate detecting header 2 and passes through  the flow rate calibrating valve 6 then through the discharge water flow rate detecting header 3,  flowmeter 7 is created for measurement of this feed and waste water flows. The differences of the  feed and waste water flows are obtained and are used as the instrument correcting values at the  measurement channel.

Title: Sawtooth wave generating circuit
Inventor: NISHITOBA SHIGEO
IPC: H03K4/08
Filed: 1981-05-25
Abstract: PURPOSE:To keep output characteristcs unchanged against an impedance change due to external environment, by comparing an output level from a control circuit with a reference voltage and controlling a time constant circuit through conduction and interruption of a transistor (TR) with the result of comparison. CONSTITUTION:A comparator 20 and an SWTR 22 are connected between a switching TR1 of a control circuit 36 for input signal application and a time constant circuit 23. When a reference voltage 21 of the comparator 20 is set so that the TR22 is conductive only with conduction of the TR1, the TRs 1 and 22 operate an in-phase. Thus, even if dust and oil are attached to a conductor 38 and an input impedance viewed from an input terminal 2 of a charge/discharge circuit 39 is changed, the charge/discharge of the circuit 23 is controlled with the TR22 and a sawtooth wave generating circuit with unchanged output characteristics can be obtained without being affected with impedance change.

Abstract: PURPOSE:To set a cap of a marine engine clamped by a cap bolt and vice versa from an access opening by installing this access opening in a lower part at the side of a cylinder block, and dividing a connecting rod into the rod and the cap horizontally in a clamp pin part. CONSTITUTION:A cap bolt 13 clamping a cap 12 of a connecting rod 10 tight enough is increased to four pieces in total. A crankshaft 3 is rotated, making the cap 12 approximate to an access opening 2 of a cylinder block 1, and a barrier wrench 20 is inserted thereinto from this access opening 2, whereby a socket 21 is set to the cap bolt 13. In succession, a ratchet wrench 23 is set to a driving hole 22 of the barrier wrench 20, thereby performing both clamping and loosening operations on the cap bolt 13, and setting of the cap 12 and vice versa is carried out from the access opening 2. Since the cap bolt 13 is four pieces in total, the extent of clamping torque is small in force so that its setting operation can lee done so easily. Accordingly, a thorough overhaul in a piston 4 is made achievable without lifting an engine down.

Filed: 1985-04-13
Abstract: PURPOSE:To produce the sure operation of a turbine and use its rotational sound as a siren by releasing a locklever checking the driving restoring force of a spring by means of the turbine rotation. CONSTITUTION:A rotatable case 8 fixed with the free end of a spring 7 is locked by a locklever 9.

IPC: B05B7/04
Filed: 1988-03-31
Abstract: PURPOSE:To improve the efficiency in depositing a paint on a material to be coated by providing an atomizing air discharge port and a pattern control air discharge port at the tip of a spray nozzle. CONSTITUTION:When a quick-drying two-pack mixed paint is sprayed, an atomizing air is discharged from a discharge port 2 at the tip of the spray nozzle 1 toward a paint spray from a tip 4 to atomize the paint. The pattern control air is discharged from the plural discharge ports 3 at the tip of the nozzle to surround the paint spray in the form of an air curtain. When the tip 4 is clogged, the tip 4 capable of being turned through an angle of 180 deg. is turned and reversed by remote control, and the clogging solid matter is removed by the discharge force of the paint. As a result, the efficiency in depositing the paint on the material is increased. The nozzle clogging due to the quick-drying two-pack mixed paint can be eliminated by remote control, and the worker is not exposed to the undesirable environment.
