Title: Neon discharge tube
Inventor: AIZAWA MASANORI
IPC: H01J61/78
Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To lengthen the sevice life, and improve reliability by arranging a powder paint film having the proper grain size in a range to cover an electrode part in a condition where a tubular bulb is observed/viewed from the perpendicular direction to the axis, on an inside surface of the tubular bulb. SOLUTION: A powder paint film 5 is formed on an inside surface of a tubular bulb 2 by joining powder having the proper grain size by a binder. The powder paint film 5 is applied to the inside surface of the bulb 2, and is made porously rich in a condition of being fixed by baking or the like. A range L where the powder paint film 5 is formed does not extend over the whole surface of an inside surface of the bulb 2, and is set to a range to cover it so that an electrode part 3a become invisible in a condition of where the bulb 2 is observed/viewed from the perpendicular direction to the axis Z. This range is set to a range hardly influencing an effective light emitting range of a neon discharge tube 1.  Therefore, a phenomenon that neon gas 4 is held inside by the cathode splashing action is prevented by a porous property possessed by the powder paint film 5, and shortening of the service life by the cathode splashing action of the neon discharge tube is prevented.

Filed: 1992-03-30
Abstract: PURPOSE:To protect a glass film against damage when a chip type thermistor is mounted on the surface by a method wherein a thermistor base chip having rounded corners is used. CONSTITUTION:A wet barrel grinding is performed onto a thermistor base chip 11 to obtain a thermistor element chip 12 in which square parts of its square corner and ridgeline parts and the like are rounded.

IPC: G21F9/08
Filed: 1993-05-21
Abstract: PURPOSE:To enhance the removing efficiency of ruthenium by reducing volatile ruthenium using a process and/or a unit (condenser) for condensing steam. CONSTITUTION:Radioactive waste liquid containing ruthenium and nitric acid is fed continuously from a waste liquid storage tank 1 to a first evaporator 2. The first evaporator 2 thermally evaporates the waste liquid to produce the vapor thereof which is fed to a first condenser 3 where the vapor is cooled and liquefied. Furthermore, NO and/or NO2 is fed from a reducing gas supply unit 4 to the condenser 3 where volatile ruthenium is reduced and dissolved into the condensed liquid. The condensed liquid is fed to a second evaporator 6 and the vapor thereof is liquefied by a second condenser 7 and fed to a purified waste liquid storage tank 8. In this regard, the volatile ruthenium and the reducing gas are caused to react in the condenser 3 and the ruthenium is reduced to a nonvolatile form having the oxidation number of 2 or 4 and dissolved into the condensed liquid. This method restrain the evaporation of ruthenium in the second evaporator 6.

Title: Robot control method
Inventor: KIMURA SHOICHI
IPC: G05B19/42
Filed: 1985-06-04
Abstract: PURPOSE:To attain a CP action at playing back in the combination with actual fine PTP actions by sampling periodically and action locus available from a manually operated robot so as to store it as NC data in a memory when the CP action is taught. CONSTITUTION:When contents in a teaching action mode buffer 1 is '1', a CPU 9 receives an interruption in an interval set to a sampling period buffer 3 by a timer interrupter 13. When the CP action (the locus of the tip of the wrist of a robot draws a straight line or an arc) is recognized, the CPU 9 reads the current value of the robot from a POS11 and sets it in a current value buffer 15. continuously contents in a current value buffer 15 are compared with those of a previous current value buffer 17. when there is a difference between them, NC data is generated by assuming that a pivot action is executed, and set in an NC data buffer 5. Upon the completion of the generation of the NC data at one sampling point, the operation is shifted to the next sampling point. When the data generation at all sampling points is terminated, the CP action is executed according to said data.

Title: Braking device
Inventor: ONUMA YUTAKA
IPC: B60T8/00
Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To execute a pressure intensifying control by which working of a brake can be stably controlled even without detecting related quantity of braking operation state quantity by utilizing speed reduction gradient of a car body before the starting of the pressure intensifying control. SOLUTION: A speed reduction gradient SP before a control is acquired as inclination of a straight line when a plurality of car body speed reduction G which are successively detected from just after the starting of a braking operation up to just before the formation of the starting condition of a pressure intensifying control are approximated by the straight line. The speed reduction gradient SP before the control is determined as it is for target speed reduction gradient SD to be realized in the pressure intensifying control. Pressure intensifying quantity ΔP for master cylinder hydraulic pressure PM of brake cylinder hydraulic pressure PB is determined so as to increase car body speed reduction G by the gradient.  Thus, the car body speed reduction G increases by the same gradient, regardless of before and after the assisting limit of a booster, and the working of a brake is stabilized. Because the pressure intensifying control can be performed even if an abnormality is generated in a master cylinder hydraulic pressure sensor, reliability for a failure of a braking device is improved.

Abstract: PURPOSE: To prevent rupture of a transformer or the like from being cused by temperature with no-off operation of a transistor by detecting the reduction of the saturated flux density due to temperature rise in the transformer and stopping the output of a pulse width nodulator according to the detection output.  
     CONSTITUTION: The primary winding 3a of a transformer 3 is connected to the collector of a transistor 4 constituting a switching element.
