Title: Plain bearing
Inventor: TANAKA YASUHISA
IPC: F16C3/14
Filed: 1978-07-07
Abstract: PURPOSE: To provide an arrangement for plain bearing, in which effective width of the slide surface is changed with the magnitude of load acted to the bearing for connecting rod, and clearance between the bearing and the shaft at the central crown portions substantially in a semicirclar form is made different from that at opposite end portions, whereby it is enabled to reduce frictional loss of the bearing.  
     CONSTITUTION: Effective width L1 at areas A1, A2 where load acted to plain bearings 5a, 5b is high is made larger, whereas that L2 at other areas where the load is low is made smaller. Assuming here that sliding direction of the bearing is in the direction of arrow shown in the drawing, there is a tendency that shortage of lubricating oil is caused at points A. In order to overcome the above difficulty, clearance C 2  between shaft 4 and the split bearing in the direction of low load is made 16W80μm larger than that C 1  in the direction of high load. By thus increasing the clearance, oil film is formed and direct contact between metals can be avoided.

Title: Measuring instrument for dynamic viscoelasticity
Inventor: IIZUKA NOBUO
IPC: G01N19/00
Filed: 1989-03-31
Abstract: PURPOSE:To measure only an amplitude which contains no offset effectively with high accuracy by calculating the center value of an input signal by a CPU from an upper-side and a lower-side peak value that a peak measuring circuit outputs. CONSTITUTION:When a length signal is inputted to a peak measuring circuit 27, upper and lower peak values are inputted to the CPU 28. The CPU 28 calculates the center value of the input signal from the upper and lower peak values and compares the calculated center value of the input signal with the center value of the input span of the circuit 27 to output a value for canceling the difference to a stepping motor driving circuit 29 when there is the difference. The circuit 29 outputs the value from the CPU 28 to a driving part to cancel the difference between the center value of the input signal and the center value of the circuit 27, and then a signal which contains no offset is inputted to the circuit 27. Therefore, even if the input signal deviates owing to the expansion, creeping, etc., of a sample, the amplitude is measured with high accuracy.

Abstract: PURPOSE:To prevent the clogging of a chute of a reaper with reaping waste. CONSTITUTION:A transmission-type photo-sensor is attached to a chute and the density of reaping waste transferred through the chute is detected by the light intensity received by a receptor 17b of the photo-sensor. The high-level detection signals of a light-receiving level outputted from the detector 28 at prescribed intervals are counted by a counter 29 and a light-shielding ratio is calculated from the counted level by a processing part 30. A rotational number calculation part 31 calculates the target rotational number of the blower motor from the light-shielding ratio and a rotational number detection part 9 detects the present rotational number of the motor. The present rotational number is made to coincide with the target rotational number by a feed-back control with a controlling part 7. A clogging prevention command is outputted by a clogging state discrimination part 10 when the light-shielding ratio exceeds a threshold value. A high-level target rotational number may be outputted from the calculation part 31 according to the clogging prevention signal.

IPC: C01B11/06
Filed: 1992-03-05
Abstract: PURPOSE:To obtain the subject catalyst capable of efficiently decomposing sodium hypochlorite without eluting into a solution to be treated by using a decomposition catalyst consisting of a multiple metal of iron and Ni. CONSTITUTION:This catalyst is obtained from the multiple metal of iron and Ni. For example, an Ni material such as an invar material is etched in a ferric chloride solution, an iron scrap is charged into an etching waste solution to deposit Ni on the surface of iron, and the powder of the multiple metal of iron and Ni is obtained by separating the powder of the multiple metal of iron and Ni deposited from the waste solution. When the decomposition catalyst obtained in this way is charged into the solution of sodium hypochlorite, sodium hypochlorite in the solution is decomposed into sodium chloride for a short time. Then, sodium hypochlorite in the solution of sodium hypochlorite is easily and efficiently decomposed to be harmless without secondary treating.
