Title: Plasma etching method
Inventor: KIMOTO TSUNENOBU
IPC: H01L21/3065
Filed: 1989-04-24
Abstract: PURPOSE:To make it possible to etch a sample of a large area uniformly and with excellent controllability by enabling execution of a glow discharge even under the atmospheric pressure by making the ratio of a material gas small while making the ratio of a rare gas large. CONSTITUTION:A mixed gas consisting of a material gas for etching and a rare gas is supplied to a discharge space between opposite electrodes so that the value obtained by dividing a whole gas flow rate Q by the volume S of the discharge space is 10<-1> to 10<-2>sec<-1>. When the mixed gas of the material gas and the rare gas is introduced from a gas introduction port 5 and a high-frequency voltage is impressed on the electrode 3, for instance, a glow discharge is generated and maintained stably even under the atmospheric pressure since the rate of the rare gas is large, and the mixed gas is excited to be a plasma by the glow discharge. The gas is supplied through numerous holes of the electrode 2 and reaches the center of the electrodes, so as to cause the discharge widely and uniformly, and thus execution of uniform etching is enabled even when a sample substrate 4 is broad. According to this method, an insulating film, a metal thin film or the like of a large area can be etched uniformly and with excellent controllability under a pressure approximating to the atmospheric pressure.

Title: High frequency oscillation type proximity switch
Inventor: HIRAO IICHI
IPC: H03K17/95
Filed: 1986-05-07
Abstract: PURPOSE:To improve the reply speed of object detection by connecting a voltage control resistive element in parallel with a resistor deciding a conductance of an oscillation circuit, amplifying inversely the detection output of the oscillation circuit to control the voltage control resistive element thereby keeping the oscillation with a prescribed small amplitude even when the object approaches. CONSTITUTION:When an object approaches the proximity switch nearer than a distance l2, the circuitry is controlled so that a conductance gx of an oscillation circuit follows a conductance ga of a resonance circuit due to the reduction in a detection voltage Vd and the oscillation is continued at nearly a constant amplitude. Then the approaching body is detected by using a prescribed value Vref being a value Vd2 or over as to the detection output Vd as a threshold level of a comparator 9. Even when the object approaches nearer than the distance l2, the amplitude of oscillation is expanded from a prescribed amplitude level. Thus, the leading of the amplitude of the oscillation circuit is quickened, the level reaches a level detecting the approach of the object in a very short time and the response speed of thc proximity switch is improved remarkably.

Abstract: PURPOSE:To provide power to the exterior in the utilization of siphonage by making liquid in an upper tank fall in a large diameter pipe through a small diameter pipe under siphonage and by returning the fallen liquid together with gas into a lower tank so that the liquid in the lower tank ascends along with the gas under differential pressure. CONSTITUTION:Holding the whole of a system under equal pressure, liquid in an upper tank 1 falls into a large diameter pipe 4 through a small diameter pipe 5 under siphonage so that a turbine 8 and a pump 9 are driven, and the fallen liquid together with gas existing therearound are introduced into a lower tank 1a. Therefore, pressure in the upper tank 1 is reduced at this time so that the liquid and the gas in the lower tank 1a have an increased pressure producing differential pressure which causes the liquid and the gas in the lower tank 1a to ascend to the upper tank 1, as an air bubble pump, under siphonage through a small diameter pipe 7. Since pressure in the system is constant as above-mentioned, difference between the potential energy of the liquid and the pressure energy of the pump 9 for delivering the fallen liquid into the lower tank 1a may be taken out to the exterior.
