IPC: C25D3/50
Filed: 1990-05-21
Abstract: PURPOSE:To obtain ruthenium plating liquid which is high in stability of a bath and little in deterioration of current efficiency by adding sulfamic acid to a ruthenium sulfate aq. soln., boiling and aging the mixture. CONSTITUTION:Sulfamic acid is added to a ruthenium sulfate aq. soln. and the mixture is boiled and aged. In this case, it is preferable that the concn. of ruthenium is regulated to about 1-100g/l and the concn. of sulfamic acid is regulated to about 10-500g/l and pH is regulated to about 4 or below. Further it is suitable that a time for boiling and aging this aq. soln. is regulated to about 0.5-48 hours especially preferably about 2-24 hours. Thereby formation of hydroxide and oxide is prevented and ruthenium plating liquid is obtained which is enhanced in stability and free from remarkable deterioration of current efficiency. This plating liquid is diluted and pH regulation is performed at a time of utilization in accordance with necessity. It is suitable that the concn. of ruthenium is regulated to about 1-25g/l and the concn. of sulfamine acid is regulated to about 10-500g/l and pH is regulated to about 0.5-4.

Title: Electronic integrator
Inventor: MARUYAMA YOJI
IPC: G01C22/00
Filed: 1987-05-26
Abstract: PURPOSE:To surely integrate the variance amount of an event to be measured by an integrator by correcting the integrated amount due to malfunction of a driving device of the integrator by controlling the driving time of the driving device by means of a timer. CONSTITUTION:An output signal is outputted to a computing element 6 every time the prescribed number of pulse signals of a pulse generator 1 are counted by a counter 2. The element 6 performs prescribed arithmetic processing based on the detection value of a detector 7 which counts the reciprocating motions of a plunger 4 and outputs the signals to a timer 8 which sets the driving time of a plunger driving circuit 3. In other words, the iron core of the plunger 4 malfunctions and the detection value of the detector 7 is different from an ON time value. In such a case, the amount caused by the malfunction of the plunger 4 is corrected when the signal of the counter 2 is outputted next. Thus it is possible to integrate accurate traveled distance data on a vehicle with an integrator 5 by controlling the ON time of the circuit 3.

IPC: G01R29/26
Filed: 1989-05-22
Abstract: PURPOSE: To measure the energy of radio-frequency interference voltage (RFI) in a short time by providing a detection circuit for measuring the maximum and minimum peak voltages and using a spectral analyzer. CONSTITUTION: In order to measure the radio-frequency interference voltage of a machine to be tested, a high frequency receiver 1 sweeps a predetermined frequency range. First and second peak voltage measuring circuits 5, 6 measure the maximum and minimum peak voltages P5, P6 simultaneously. When a judgement is made that the measurement of circuit 5 exceeds a reference limit level, sweeping operation of receiver is interrupted immediately. Noise of the machine to be tested is narrow band noise if the levels P5 and P6 are equal to each other, otherwise it is a modulated signal or a pulse-like fluctuation noise. It is related to wide band noise. A quasi-peak value is then measured and when it exceeds a specified limit level, the machine to be tested is a noise source and thereby it is rejective.

IPC: G11B5/31
Filed: 1986-06-06
Abstract: PURPOSE:To decrease the coercive force in the difficult axis direction of a magnetic film applicable to a thin film magnetic head and to increase reading- out capacity by controlling the average crystal grain size of the film. CONSTITUTION:The film having the small coercive force has the large average crystal grain size. More specifically, the average crystal grain size of an NiFe film formed on a glass substrate is preferably specified to >=0.1mum and <=0.5mum in order to maintain <=10e coercive force in the difficult axis direction which is the essential requirement for the magnetic film for the magnetic pole of the thin film magnetic head in the relation between the average crystal grain size of the NiFe film and the coercive force in the difficult axis direction. Such grain size is attained by increasing the film forming speed to >=20Angstrom /S to obtain >=0.1mum average crystal grain size of the sputtered film and regulating the sputtering gaseous pressure to obtain <=0.5mum average crystal grain size.

Abstract: PURPOSE:To take a measurement of fine clearance with high accuracy by simple constitution by providing a dielectric film on the end surface of a semiconductor laser on the side of a body to be measured. CONSTITUTION:Projection light 5 from one output end surface 4 of the semiconductor laser 1 is emitted on a reflecting body 6, its reflected light 7 reflected by the reflecting body 6 is fed back to the laser 1, and the light output 8 of the other output end surface 4 is detected by a photodetector 3.
