Title: Method for easily measuring viscosity of run-off oil, bucket for collecting run-off oil, and method for collecting run-off oil
Inventor: TAKAHASHI SHINJIRO
IPC: E02F3/47
Filed: 1999-05-11
Abstract: PROBLEM TO BE SOLVED: To measure the viscosity of run-off oil by throwing spheres with different specific gravity into the sample of the run-off oil being accommodated in a container for settling and then measuring settlement time until the spheres disappear. SOLUTION: For measuring the viscosity of run-off oil, a simple table for judging kinetic viscosity using a glass sphere 3 and an iron sphere that are made of two materials is created. As a result, by quietly placing the spheres on the oil surface of the sample of the run-off oil that is scooped in the field, settlement time is measured until the spheres completely disappear when viewed from an upper part, thus measuring viscosity from the simple table. For gathering the run-off oil, the width of the slit being provided at the shell of a bucket 5 such as a glove bucket, a latch arm bucket, and an orange peel and/or the diameter of a hole are reduced at low viscosity and a bucket with a large diameter is used in high viscosity depending on the viscosity of oil that runs out and is floated to separate and gather oil and seawater.  A bucket that is fitted to a derrick ship 7 according to the viscosity of the run-off oil is fitted in a gathering operation for carrying up a pier by a carrier ship 8 after being scooped by the bucket 5.

Abstract: PURPOSE:To enable simple and convenient measurement of the flow rate of an exhaust gas without having an adverse effect on the performance of a combustion apparatus, by supplying an inactive gas as a tracing gas and by measuring the concentration of the tray gas in the exhaust gas. CONSTITUTION:A tracing gas (g) being an inactive gas is made to flow into an air supply passage 2 connected to an engine 1, by a tracing gas supply passage 5, via a regulator 6, a pressure gage 7, a thermometer 8 and a critical flow venturi(CFV) 9. A part of an exhaust gas EG discharged into an exhaust gas flow passage 4 from the engine 1 is collected by a branch flow passage 10, and a tracing gas analyzer 13 provided in the flow passage 10 measures the concentration of the tracing gas (g) in the EG and outputs a concentration signal Cg. An arithmetic unit 14 receives a flow coefficient of the CFV 9, the concentration signal Cg, a pressure signal P of the pressure gage 7 and a temperature signal of the thermometer 8 as inputs and determines a flow rate QEX of the exhaust gas by computation. On the occasion, the tracing gas for which the inactive gas such as helium is supplied is mixed sufficiently with the exhaust gas and the flow rate of the exhaust gas can be measured simply and conveniently without having an adverse effect on the performance of the engine.

Title: Gas/liquid separating device for blowby gas
Inventor: SHIBATA TAKUJI
IPC: F01M13/04
Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To eliminate adverse effects on the performance of an engine through reliable separation of oil and suppression of wear of its cylinders with a gas/ liquid separating device, and lessen the load on the engine through simplified structure and reduced weight of the separating device effected at smaller cost. SOLUTION: A blowby gas passage 13 is provided so as to be communicated from a crankcase with a breather chamber 401 defined by a head cover 3, and a blowby gas inflow port 14 is formed between the blowby gas passage 13 and the breather chamber 401 so as to regulate the inflow direction of the blowby gas that is led by the blowby gas passage 13 into the breather chamber 401. That constitution accelerates the blowby gas flowing into the breather chamber 401, optimizes the flowing direction of the gas, and ensures oil separation through oil separation and oil drop collection due to differences in specific gravity. That constitution also simplifies the structure of the cover 3 for its smaller manufacturing cost and reduced weight to lessen the engine load.

Title: Torque detector
Inventor: IMAMURA NOBUAKI
IPC: B25J15/08
Filed: 1991-06-03
Abstract: PURPOSE:To accurately detect the torque acting around the periphery of an oscillating axis by making the distances between the oscillating axis of an oscillating member and the working positions of two wire bodies different from each other and measuring the moment generated by a tension difference. CONSTITUTION:The distance R1 from the oscillating axis O1 of an arm 4 to the working position A1 of a wire 1 is made different from the distance R2 from the axis O1 to the working position A2 of another wire 2 and the wires 1 and 2 are wound from the opposite directions. It is contrived that a moment M proportional to the torque taua acting around the oscillating axis of the arm 4 is generated in a sensor beam 7 based on the difference between forces F1 and F2 produced by the tensions T1 and T2 of the wires l and 2. In other words the ratio of the distance L2 from the axis O1 to the position A20 where wire 2 comes into contact, with a pulley 9b to the distance L1 from the supporting fulcrum O2 of pulleys 9a and 9b to the position A10 where the wire 1 comes into contact with the pulley 9a is made equal to the ratio of the distance R2 to the distance R1. Therefore the moment M proportional to the torque taua is generated in the beam 7 supporting the pulleys 9a and 9b respectively supporting the wires 1 and 2 due to the difference between tension T1 and T2 of the wires 1 and 2 and the torque taua can be detected when the moment M is measured.

Title: Cold storage
Inventor: YAMADA TETSURO
IPC: F25D11/00
Filed: 1988-05-27
Abstract: PURPOSE:To quickly cool a cold storage while improving handiness by automatically beginning rapidly cooling operations when the temperature of the cold storage is equal to or higher than the fixed temperature at which the cold storage temperature is set in normal cooling operation, or when a continuous operation time of a compressor has become equal to or more than the fixed time. CONSTITUTION:When the temperature of a freezing chamber is heightened up to compressor-on temperature (for example, -18 deg.C), a compressor 4 and a fan motor 5 are switched on to drive at the time t1. When the temperature of the freezing chamber is lowered down to compressor-off temperature (for example, -21 deg.C), the compressor 4 and the fan motor 5 are driven at the time t2 intermittently. When the freezing chamber is overloaded, the temperature is rapidly heightened at the time t3 and a relay switch 6 is turned on at the time t4 and the compressor 4 and the fan motor 5 are switched on to drive. When the temperature is heightened up to rapidly cooling operation beginning temperature (for example, -10 deg.C) of the fixed temperature set higher than the compressor-on temperature, at the time t5 the rapidly cooling operation of the fan motor 5 is started at rotating speed which is more than normal cooling rotating speed.
