Title: Gaseous hydrogen sensor
Inventor: YOSHIIKE NOBUYUKI
IPC: G01N27/12
Filed: 1984-04-06
Abstract: PURPOSE:To increase the sensitivity of a hydrogen sensor by making use of the decrease in the resistance value of tungsten oxide when gaseous hydrogen is absorbed to the tungsten oxide. CONSTITUTION:The 1st electrode 2 and the 2nd electrode 4 are provided on a substrate 1. The 1st electrode 2 is made of Pt, Pd, Ti, etc. and the 2nd electrode 4 of Pd, etc. A WO3 film 3 is formed on the electrode 2 and under the electrode 4 to 4.0-6.0g/cm<3> packing density and 100-10,000Angstrom  film thickness, thereby constituting a hydrogen sensor. When hydrogen is brought into contact with the sensor, the hydrogen is absorbed by the film 3 by the catalytic effect of Pt, etc. of the electrode 4, by which the resistance value thereof is decreased and the resistance 7 between the 1st electrode 2 and the 2nd electrode 4 is decreased. The hydrogen is consequently more absorbed by the WO3 film and the resistance is lower as the concn. of the hydrogen is higher. The hydrogen is thus detected with high sensitivity.

Filed: 1986-03-27
Abstract: PURPOSE:To improve the control accuracy of a compensating device for revolution variance by feeding the variance same as that of a revolution transmission system for reduction gear, etc., that causes vibrations back to a control system independently of other types of variance. CONSTITUTION:A motor 1 drives the load of a robot arm, etc., via a harmonic drive reduction gear 2 of a revolution transmission system. A position detector 3 of a rotary encoder, etc., is connected to the drive shaft of the motor 1. The position information (rotational angle information) obtained from the detector 3 is usually counted by a pulse counter 4 with a certain Z pulse defined as a start point. The phase of a signal generator 5 is controlled by a phase controller 6. Then the output signal of an adder 8 is sent to a robot arithmetic unit 9 of a computer which controls the drive of the motor 1. Thus the unit 9 feeds the received signal back to a drive circuit 10 of the motor 1 for automatic control to eliminate the revolving variance of the gear.
